To evaluate the cardiopulmonary endurance of subjects with spinal cord injury by measuring the maximal oxygen consumption with varying degrees of spinal cord injury level, age, and regular exercise.
We instructed the subjects to perform exercises using arm ergometer on healthy adults at 20 years of age or older with spinal cord injury, and their maximal oxygen consumption (VO2max) was measured with a metabolic measurement system. The exercise proceeded stepwise according to the exercise protocol and was stopped when the subject was exhausted or when VO2 reached an equilibriu
Among the 40 subjects, there were 10 subjects with cervical cord injury, 27 with thoracic cord injury, and 3 with lumbar cord injury. Twenty-five subjects who were exercised regularly showed statistically higher results of VO2max than those who did not exercise regularly. Subjects with cervical injury showed statistically lower VO2max than the subjects with thoracic or lumbar injury out of the 40 subjects with neurologic injury. In addition, higher age showed a statistically lower VO2max. Lastly, the regularly exercising paraplegic group showed higher VO2max than the non-exercising paraplegic group.
There are differences in VO2max of subjects with spinal cord injury according to the degree of neurologic injury, age, and whether the subject participates in regular exercise. We found that regular exercise increased the VO2max in individuals with spinal cord injury.

Supernumerary phantom limb (SPL) resulting from spinal cord lesions are very rare, with only sporadic and brief descriptions in the literature. Furthermore, the reported cases of SPL typically occurred in neurologically incomplete spinal cord patients. Here, we report a rare case of SPL with phantom limb pain that occurred after traumatic spinal cord injury in a neurologically complete patient. After a traffic accident, a 43-year-old man suffered a complete spinal cord injury with a C6 neurologic level of injury. SPL and associated phantom limb pain occurred 6 days after trauma onset. The patient felt the presence of an additional pair of legs that originated at the hip joints and extended medially, at equal lengths to the paralyzed legs. The intensity of SPL and associated phantom limb pain subsequently decreased after visual-tactile stimulation treatment, in which the patient visually identified the paralyzed limbs and then gently tapped them with a wooden stick. This improvement continued over the 2 months of inpatient treatment at our hospital and the presence of the SPLs was reduced to 20% of the real paralyzed legs. This is the first comprehensive report on SPLs of the lower extremities after neurologically complete spinal cord injury.

We report on operational and rehabilitation management, as well as the outcome, of a patient who with sustained spinal cord injury from a high velocity gunshot wound to the lumbar spine. More specifically, a patient with a gunshot wound to the spine is more likely to sustain a complete injury and have a poor prognosis. As such, there should be concerns regarding associated and extended injuries related to bullet fragmentation as well as the possibility of long-term sequelae.

Spinal cord injury (SCI) without radiographic abnormality (SCIWORA) is estimated to account for 1-9% of the occurrence of SCI. Of these, cervical SCIWORA in children is common, but thoracic SCIWORA delayed onset in adult is much less common. We experienced a case of 38-years old male patient with lower extremity weakness; he had fallen down a week earlier before the investigation. At the time of admission, motor grade was 4 with voiding incontinence and ambulated with cane. He presented progressive weakness from G4 to G3 and hypoesthesia was below T8 dermatome and ambulated with wheelchair. Whole spine and lumbar MRI findings showed no abnormality and electrodiagnostic findings showed normal NCS, however, abnormal SEP on both the tibial nerves. After steroid therapy and proper rehabilitation program for 2 weeks, lower extremity strength was improved from G4 to G3, voiding was continent, and ambulation reached cane gait.

To evaluate the feasibility of the ICF for initial comprehensive evaluation of early post-acute spinal cord injury.
A comprehensive evaluation of 62 early post-acute spinal cord injury (SCI) patients was conducted by rehabilitation team members, such as physicians, physical therapists, occupational therapists, nutritionists, medical social-workers, and nurses. They recorded each of their evaluation according to the ICF first level classification. The contents of the comprehensive evaluation were linked to the ICF second level categories, retrospectively. The linked codes were analyzed descriptively and were also compared with the brief ICF core set for early post-acute SCI.
In the evaluation of early post-acute SCI patients based on the ICF first level categories, 19 items from the body functions domain, such as muscle power functions (b730) and urination functions (b620), 15 items from the body structures domain, including spinal cord and related structures (s120), 11 items from the activities and participation domain, such as transferring oneself (d420) and walking (d450), and 9 items from the environmental factors domain, e.g., health professionals (e355), were linked to the ICF second level categories. In total, 82.4% of all contents were linked to the brief ICF core set. Prognosis insight, a personal factor not linkable to an ICF code, was mentioned in 29.0% of all patients.
First level ICF categories can provide a structural base for a comprehensive evaluation in early post-acute spinal cord injury. However, frequently linked items, including the brief core set, as well as personal factors should be considered via a checklist in order to prevent the omission of significant contents.

Massage is generally accepted as a safe and a widely used modality for various conditions, such as pain, lymphedema, and facial palsy. However, several complications, some with devastating results, have been reported. We introduce a case of a 43-year-old man who suffered from tetraplegia after a neck massage. Imaging studies revealed compressive myelopathy at the C6 level, ossification of the posterior longitudinal ligament (OPLL), and a herniated nucleus pulposus (HNP) at the C5-6 level. After 3 years of rehabilitation, his motor power improved, and he is able to walk and drive with adaptation. OPLL is a well-known predisposing factor for myelopathy in minor trauma, and it increases the risk of HNP, when it is associated with the degenerative disc. Our case emphasizes the need for additional caution in applying manipulation, including massage, in patients with OPLL; patients who are relatively young (i.e., in the fifth decade of life) are not immune to minor trauma.

To investigate the factors influencing the quiet standing balance of patients with incomplete cervical spinal cord injuries. Also to find the correlations between posturographic parameters and clinical balance tests as well as to find the correlation between posturographic parameters and functional independence.
We conducted a tetra-ataxiometric posturography, lower extremity motor score (LEMS), Korean version of the Berg Balance Scale (K-BBS), Timed Up and Go test (TUG), and Korean Version of the Modified Barthel Index (K-MBI) of 10 patients. 10 healthy adults carried out the posturography. We checked stability, weight distribution, Fourier and synchronization indices of eight positions, and the fall index of the posturography.
The patient group showed significantly higher stability and weight distribution indices in all eight positions. Stability indices significantly increased with eyes closed or standing on pillows. Weight distribution indices were significantly higher with eyes closed or the head bent backwards. The patient group showed significantly higher Fourier indices of low, low-medium, and high frequency in eight positions. The Fourier indices at high-medium frequency were significantly higher with eyes closed on pillows or in variable head positions. There were no significant differences of synchronization indices between the patient and the control group. The falling index of the patient group significantly correlated with K-BBS, TUG, and K-MBI. LEMS had significant correlation with some synchronization indices, but not with the falling index.
The quiet standing balance of the patients was influenced by somatosensory limitations or insufficient visual compensation. We should try to improve the postural balance and functional independence of patients through proper proprioceptive and lower extremity strength training for better postural and pedal control, and to make efforts to minimize environmental hazards.

To examine the cardiorespiratory responses of patients with spinal cord injury (SCI) paraplegia using a motor driven rowing machine.
Ten SCI patients with paraplegia [A (n=6), B (n=1), and C (n=3) by the American Spinal Injury Association impairment scale] were selected. Two rowing techniques were used. The first used a fixed seat with rowing achieved using only upper extremity movement (fixed rowing). The second used an automatically moving seat, facilitating active upper extremity movement and passive lower extremity movement via the motorized seat (motor rowing). Each patient performed two randomly assigned rowing exercise stress tests 1-3 days apart. The work rate (WR), time, respiratory exchange ratio (R), oxygen consumption (VO2), heart rate (HR), metabolic equivalents (METs), and rating of perceived exertion (RPE) were recorded.
WR, time, VO2, and METs were significantly higher after the motor rowing test than after fixed motor rowing test (p<0.05). HR after motor rowing was significantly lower than fixed rowing (p<0.05).
Cardiorespiratory responses as VO2, HR and METs can be elicited by the motor rowing for people with paraplegic SCI.

To investigate the effect of radiofrequency (RF) sacral rhizotomy of the intolerable neurogenic bladder in spinal cord injured patients.
Percutaneous RF sacral rhizotomy was performed on 12 spinal cord injured patients who had neurogenic bladder manifested with urinary incontinence resisted to an oral and intravesical anticholinergic instillation treatment. Various combinations of S2, S3, and S4 RF rhizotomies were performed. The urodynamic study (UDS) was performed 1 week before RF rhizotomy. The voiding cystourethrogram (VCUG) and voiding diaries were compared 1 week before and 4 weeks after therapy. Total volume of daily urinary incontinence (ml/day) and clean intermittent catheterization (ml/time) volume of each time were also monitored.
After RF sacral rhizotomy, bladder capacity increased in 9 patients and the amount of daily urinary incontinence decreased in 11 patients. The mean maximal bladder capacity increased from 292.5 to 383.3 ml (p<0.05) and mean daily incontinent volume decreased from 255 to 65 ml (p<0.05). Bladder trabeculation and vesicoureteral reflux findings did not change 4 weeks after therapy.
This study revealed that RF sacral rhizotomy was an effective method for neurogenic bladder with uncontrolled incontinence using conventional therapy among spinal cord injured patients.

To evaluate the severity of depression, degree of life satisfaction, level of stress, and resilience among patients in the first 6 months after a spinal cord injury (SCI).
36 patients with SCI were asked to fill out questionnaires concerning Beck Depression Inventory (BDI), World Health Organization Quality of Life Questionnaire-BREF, Stress Response Inventory, and Connor-Davidson resilience scale. All patients had experienced an SCI within the last 6 months before the commencement of this study.
In our study, the patients who experienced the SCI within the last six months had a higher rate of depression (63.9%) and a higher overall level of depression (13.8 points). The unmarried group had a significantly higher quality of life (QOL; p<0.05) when compared with the married group. In the motor complete group, severity of depression and level of stress were higher, whereas QOL was lower than the motor incomplete group (p<0.05). The mean American Spinal Injury Association (ASIA) Motor Score (AMS) was much higher in the non-depressive group (p<0.05) when compared with the depressive group.
We found the patients within six months after SCI injury had higher rate of depression and higher overall level of depression. Also, patients with motor complete injury had affected significantly on depression, QOL and stress. We found the married patients had poorer QOL and depressive group had lower AMS score of lower extremity. Therefore, there should be emphasis of psychological care who have motor complete injury and are married during the early stage.

To provide the latest statistics about the length of hospital stay (LOS) and the number of hospitals where the patient was admitted (NHA) for patients with spinal cord injury (SCI) and to investigate the correlated demographic characteristics.
In total, 277 patients with SCI who were members of the Korea Spinal Cord Injury Association were included in the analysis. The survey was conducted by self-completed questionnaires to collect data on LOS, NHA, and demographic variables.
Mean LOS was 13.5±9.7 months and the mean NHA was 2.7±1.4. Patients who suffered from SCI by traffic accidents showed a longer LOS and larger NHA than those with other causes. The mean LOS for patients with traumatic SCI was longer than that whose cause of injury was disease. Patients discharged in the 2000s had a longer LOS and a larger NHA than those discharged earlier. Other factors such as gender, age at the time of injury, neurological category, and ambulation capability did not result in a significant difference in either LOS or NHA.
The mean LOS of domestic patients with SCI was longer than the values reported in foreign studies. Interestingly, neither neurological category nor functional status were related to LOS. These findings suggest that other factors such as socio-psychological factors, other than the medical state of the patient, have an effect on the LOS of patients with SCI in Korea.

To estimate hours of leisure time physical activity (LTPA) performed by people with chronic spinal cord injury (SCI) and to identify the demographic and injury-related characteristics associated with LTPA of people with chronic SCI.
Seventy nine persons with SCI living in Busan and Gyongsangnam-do were recruited. They completed a self-administered questionnaire, which consisted of items about personal characteristics, type of LTPA, hours of LTPA, LTPA intensity, and LTPA satisfaction.
Most participants (92.4%) did not work. The respondents reported a daily mean of 3.13 hours (±1.47) of LTPA; however, 3.8% reported no LTPA whatsoever. Years post-injury, income sources, and type of medical payment emerged as a predictors of LTPA. Years post-injury were positively correlated with amount of leisure activity. In the case of self income, LTPA was longer than for groups with different income sources (e.g.partner, parents). For patients receiving workers' compensation insurance, LTPA was longer than for patients receiving non-WC insurance. Most LTPA was done at a moderate intensity. The three most frequently reported types of LTPA were wheeling (26%), sports (19%), and stretching exercise (15%). There was overall dissatisfaction with LTPA.
Daily LTPA hours were longer than previously reported, but wheeling accounted for a large part of the activity. Intensity of activity was generally moderate. The employment rate was very low. Clearly, participating in regular LTPA for health purposes is very important to people with chronic SCI, but it is also important for them to have jobs.

To investigate changes in (1) the colonic response to acetylcholine (Ach), (2) the muscarinic (M) receptors in the colon, and (3) the levels of colonic contraction-related proteins after a spinal cord injury (SCI).
We divided 16 Sprague-Dawley rats into 2 groups: the control group and the SCI group. A spinal cord transection was performed surgically at the T10 vertebral level. After 1 week, the entire colon was divided into 2 segments, the proximal and distal colon. Each segment was mounted in a longitudinal or circular muscle direction in a 10-ml organ bath. We determined the intergroup differences as percentage changes in contractility after Ach treatment alone, Ach treatment with M2 receptor antagonist (AQ-RA741) pretreatment, and Ach treatment with M3 receptor antagonist (4-DAMP) pretreatment. Western blot analyses were performed to determine the expression level of RhoA, and heat shock protein 27 (HSP27).
Compared to the control rats, the SCI rats showed an increased response to Ach along both the directions in the proximal colon (p<0.05). Compared to the control group, in the SCI group, the Ach response was significantly different in the proximal segment under AQ-RA741 pretreatment (p<0.05) and in the distal segment under 4-DAMP pretreatment (p<0.05). Findings of the western blot analyses showed a significant decrease in the level of protein gene product 9.5 in the proximal and distal colon and a significant increase in the level of RhoA and HSP27 in the proximal colon of the SCI rats.
Our results suggest that changes in colonic contractility after SCI are partly attributable to changes in the M receptor subtypes.

A 49-year-old man received prolotherapy in the upper cervical region at a local medical clinic. Immediately after the procedure, he felt a sensation resembling an electric shock in his right upper and lower extremities, and continuously complained of numbness and discomfort in the right hemibody. He visited our clinic a week later. Upon physical examination, there were no significant abnormal findings. The visual analog scale was 60 points. T2-weight magnetic resonance images of the cervical spine showed a 0.7 cm sized bright oval spot on the right side of the spinal cord at the level of C4-C5 disc, suggesting spinal cord injury. There were no definite electrodiagnostic abnormalities. Digital infrared thermal images showed moderately decreased surface temperature on lateral aspect of the right forearm and dorsum of the right hand compared with the other side. Considering that very rare complications like spinal cord injury may develop after prolotherapy, we suggest that special interventions such as prolotherapy be performed by professional experts.

Significant technical advance during the past decade have influenced the manner in which electrical stimulation may be administered to assist the functional recovery of paralyzed organ. Functional electrical stimulation (FES) is defined as the use of electrical stimulation to activate paralyzed or paretic muscles in precise sequence and intensity to assist in the performance of activities of daily living. An FES system generally consists of a control unit, stimulator unit, and electrode. The control unit determines the intensity of electrical stimulus applied to the patient through the electrodes. The stimulator unit generates the electrical stimulus. Depending on the application, FES components may be worn externally or surgically implanted. Hand neuroprosthesis system can enhance significantly the upper extremity functions of quadriplegics. Several lower extremity systems with and without bracing are being investigated for the purpose of ambulation, transfer, and standing for persons with paraplegia. Diaphragmatic pacing can be used as more physiologic artificial ventilator for high quadriplegic patient with respiratory failure. System for bladder contraction can provide catheter-free micturition for persons with supra-sacral cord injury. While there appears to be great potential for its use in a number of medical conditions, further research and clinical study is needed to truly demonstrate its clinical benefit before it gains more widespread acceptance and use.
Conclusion:
Objective: The purposes were to determine the baseline colon transit time (CTT) and to assess the effect of dietary fiber (psyllium husk) on neurogenic bowel function in chronic spinal cord injured (SCI) persons.
Method: Eleven chronic spinal cord injured persons with upper motor neuron type neurogenic bowel were participated. Personal interview were carried out for all studied subjects at pre and post treatment period. The baseline colon transit time (CTT) were measured for the right (rCTT), left (lCTT), rectosigmoid (rsCTT) colons as well as for the entire colon using radio-opaque markers. After 4 weeks treatment of psyllium husk, the subjects were reevaluated for their CTTs and the results were compared to the pretreatment values.
Results: The mean age of the subjects was 33.9⁑11.0 years and the level of injury ranged from C3 to T10. The mean duration after SCI was 22.6 months (6∼47 months). The rCTT, lCTT, rsCTT and tCTT were not affected after the treatment of psyllium husk. Also their bowel care patterns and satisfaction were unaffected by the treatment.
Conclusion: The results of this study suggest that the use of psyllium husk in chronic spinal cord injured persons do not show the same effect on bowel function as has been previously reported in general population with idiopathic constipation. (J Korean Acad Rehab Med 2002; 26: 533- 538)
Method Twenty seven rats with a model of complete spinal cord injury were assigned to one of the following groups: control (n=9), electrical stimulation (n=10), and exercise (n=8) groups. After a 2-week intervention period, they were sacrificed, and the pattern of apoptosis was analyzed by in situ DNA nick-end labeling (TUNEL), by DNA fragmentation assay, and by Western blot for Bax and Bcl-2 using specimens from the right hamstring muscles for all groups.
Results The electrical stimulation group had increased apoptosis compared to the control group possibly due to overwork weakness, but there was no statistical significance between the groups. Apoptosis decreased in the exercise group compared with in the electrical stimulation and control group. The expression of Bcl-2 was most prominent in the exercise group, and it was significantly reduced in the electrical stimulation and control group.
Conclusion These findings suggest that exercise could play an important role in decreasing apoptosis by the up-regulation of Bcl-2 protein expression and that electrical stimulation might cause overwork weakness in rat models of spinal cord injury.
Objective: The patients with spinal cord injury (SCI) suffered by a lot of complications that influence the quality of life both physically and mentally. The purpose of this study was to evaluate the epidemiology of patients with spinal cord injury in incidence of the complication according to the injury level and period.
Method: Retrospective study was done in 554 patients with SCI who discharged from Yonsei University Medical Center from January, 1987 to December, 1996. We investigated the incidence of each complication such as respiratory, cardiovascular, genitourinary, musculoskeletal, and dermatologic complications according to the neurologic level and each period (1987∼1991, 1992∼1996).
Results: Among the 554 cases, urologic complication (40.3%) was the most common complication followed by dermatologic (39.0%), musculoskeletal (33.6%), cardiovascular (27.1%) and so on. The most common complications of each system were autonomic dysreflexia (13.2%) in cardiovascular, pneumonia (9.6%) in respiratory, contracture (27.8%) in musculoskeletal, urinary tract infection (34.3%) in urologic, hemorrhoid in gastrointestinal, and central pain (24.0%) in neurogenic complications. The most common site of pressure sore was sacral area (58.9%). There was no significant difference in each complication according to the injury period.
Conclusion: Urologic complication was the most prevalent in patients with SCI followed by dermatologic, musculoskeletal and so on. These basic results would be helpful for prevention and management of the complication of SCI.
Dysesthetic pain syndrome is a common disabling painful sequelae of spinal cord injury patients.
The purposes of this study were to gather the general informations of pain in spinal cord injury patients and to investigate the correlation between the various factors affecting pain severity.
Twenty-seven spinal cord injury patients with dysesthetic pain were evaluated by medical histories, physical and neurological examinations. The pain intensity was measured by a visual analogue scale.
Twenty-one subjects were males and six were females. The mean age of patients was 35.1 years.
The patients were classified into five pain categories : diffuse pain, segmental pain, root pain, visceral pain, and non-neurogenic pain. Nineteen patients (70.4%) were categorized into diffuse pain group, six patients (22.2%) into both diffuse and segmental pain group, two patients (7.4%) into root pain group and five patients (18.5%) into perianal pain group.
According to this study, the only significant factor affecting the severity of dysesthetic pain in spinal cord injury patients was the severity of spinal cord injury. Pain appeared earlier and more intensely in the complete spinal cord injury patients. There was no correlation between the severity of pain and the level of lesion, age, or the posterior tibial nerve SEP response.
The current available treatment methods of spasticity are consisted of physical therapies, medications, surgeries, injections of phenol or botulinum, and electrical stimulations. The purposes of this study were to evaluate the effectiveness of surface electrical stimulation in reducing spasticity in the spinal cord injured patients, to find out carry-over effects of electrical stimulation and to find out the factors influencing the effects of the treatment.
The subjects were 10 quadriplegics with the cervical cord injuries. The electrical stimulation was applied to the antagonists of major spastic muscles of the knee joints for 2 weeks. The evaluation of spasticity were done by using the modified Ashworth scale, beats of ankle clonus, patellar tendon reflex(latency and amplitude), and relaxation index of patellar knee by pendulum test before and after treatment sessions.
The results of the study revealed no statistically significant changes in relaxation index, modified Ashworth scale, ankle clonus and the latency and amplitude of patellar tendon reflex(P＜0.05), however there were tendencies of improvement in relaxation index and modified Ashworth scale after the stimulations. We could not find out statistically significant factors influencing the effects of the surface electrical stimulation.
Further investigations to assess the mechanism of electrical stimulation and the adquate parameters of electrical stimulation in a larger population of subjects will be needed.
Objective: To investigate the immediate effect of dorsal penile nerve (DPN) stimulation on detrusor pressure (Pdet) and blood pressure (BP) during hyper-reflexic contractions of the bladder in patients with cervical spinal cord injury (SCI).
Method: The subjects were eight male patients with cervical SCI who had symptoms of autonomic dysreflexia. During water-cystometry, BP was monitored using an intra-arterial catheter into the radial artery, and was recorded simultaneously with the Pdet. Electrical stimulation was applied to the DPN, using surface electrodes each time a bladder contraction was detected. Baseline BP and BP at the first and the last hyper-reflexic contractions of bladder were measured with Pdet, respectively.
Results: As Pdet increased, the BP increased in all cases. The reflex contractions of the bladder were effectively suppressed by DPN stimulation, and as the Pdet decreased during stimulation, radial arterial pressure also decreased immediately and significantly.
Conclusion: DPN stimulation can lower both Pdet and the elevated BP. (J Korean Acad Rehab Med 2002; 26: 409- 413)
Objective: The purpose of this study was to investigate the risk factors of adhesive capsulitis and the effect of intra-articular steroid injection in spinal cord injured patients.
Method: Fifty spinal cord injured patients participated in this study. The risk factors of adhesive capsulitis were compared between fourteen patients with adhesive capsulitis and thirty-six patients without one. Methylprednisolone acetate 40 mg mixed with 0.5% lidocaine 2 ml was given into glenohumeral joint space in adhesive capsulitis group and their pain and range of motion (ROM) were analyzed.
Results: 1) The incidence of adhesive capsulitis was higher in patients with higher injury level, older age and delayed start of rehabilitation therapy.
2) 10 cm visual analogue scale scores were significantly decreased after intra-articular steroid injection (p＜0.01).
3) The shoulder ROM was increased after intra-articular steroid injection.
The shoulder ROM at pre-injection was 126o in flexion, 113o in abduction, 64o in external rotation and 51o in internal rotation. The shoulder ROM at 4 weeks after injection was 138o in flexion, 131o in abduction, 74o in external rotation and 77o in internal rotation.
Conclusion: There was a trend that the incidence of adhesive capsulitis was higher in patients with higher injury level, older age and delayed start of rehabilitation therapy. Further, it was suggested that intra-articular steroid injection was effective for reducing pain and improving ROM.
Objective: To investigate the difference of outcome variables and demographic features between traumatic and non-traumatic spinal cord injury (SCI) patients.
Method: Medical records of 87 spinal cord injured patients were retrospectively reviewed. The patients were divided into traumatic and non-traumatic groups. The etiology, level and completeness of SCI were investigated. The functional evaluation was performed by Frankel's classification, American spinal cord injury association (ASIA) motor and sensory scores, and modified Barthel scores at the time of admission and discharge. Bladder function and emptying method were also investigated.
Results: Spinal cord injury of non-traumatic etiology was more likely to result in a incomplete injury and more prevalent in females. At admission, the ASIA motor and sensory scores and modified Barthel index of non-traumatic spinal cord injury patient were higher than those of traumatic patients. At discharge, same results were observed for ASIA motor and sensory scores, but the modified Barthel scores showed no difference between the two groups. The changes of the scores between time of admission and discharge showed no significant difference in the two groups. There was no significant difference of bladder type and bladder emptying method.
Conclusion: This study suggest that favorable outcome in non-traumatic spinal cord injury patients might be due to better functional status at the time of admission and not due to the degree of recovery.
Objective: The purpose of this study was to determine the clinical usefulness of KCl provocative urodynamic study in spinal cord injured patients with neurogenic bladder.
Method: Urodynamic studies using normal saline and 0.2 M KCl solution were performed on 46 spinal cord injured patients. The reflex volume was measured on urodynamic study using normal saline and 0.2 M KCl solution. If the reflex volume using KCl solution was smaller than 85% of reflex volume using normal saline, it was considered as positive response. Urine culture and urinalysis were also performed before urodynamic study.
Results: KCl provocative tests showed positive response in patients showing current infection on urine culture and urinalysis (p＜0.05). Comparing with the positive response group and negative response group, mean maximal bladder capacity was smaller and mean bladder compliance was lower in the positive response group (p＜0.05). No significant differences were found between positive and negative response groups according to age, duration since injury, completeness of injury, voiding methods, and anticholinergic medication. The mean reflex volume provoked by KCl solution was smaller and mean bladder compliance provoked by KCl solution was lower than those provoked by normal saline in the positive response group (p＜0.01).
Conclusion: The response of KCl provocative test suggested increased bladder-blood-urine barrier permeability by current urinary tract infection. We conclude that the KCl provocative urodynamic study is a useful method for detection of impaired bladder-blood-urine barrier in spinal cord injuries with neurogenic bladder.
Objective: The objectives of this study were to evaluate the reliability of the Korean version of Spinal Cord Independence Measure (SCIM) and to compare the sensitivity of the SCIM to functional changes of spinal cord injury (SCI) patients with that of the Functional Independence Measure (FIM).
Method: Seventeen subjects with SCI were studied. The SCIM was translated and modified to convert as SCIM Korean-version. All patients were evaluated with the SCIM and the FIM by two raters every other week. To determine inter-rater reliability, the relationship between the SCIM scores obtained by two raters was evaluated by Kappa coefficient and linear regression. To determine relative sensitivity of the test to functional changes, changes in the scores on the SCIM and FIM were compared by McNemar test.
Results: The Kappa coefficient of the various individual tasks in SCIM ranged between 0.63 and 1.00. High correlations were also found between the total SCIM scores for the paired raters (r=0.99, p＜0.01). The SCIM detected all the functional changes detected by FIM total scoring, but in 3 (14%) of 22 sequential test batteries, the FIM missed changes detected by SCIM total scoring.
Conclusion: These results demonstrated that the SCIM is reliable and more sensitive than the FIM in reflecting the functional changes of SCI patients.
Objective: To evaluate safely the driving ability of the handicapped with developed driving simulator in the virtual environment and to investigate clinical usefulness.
Method: A real car was remodeled for realism and equipped it with hand control device for driving of the handicapped. The subjects were 10 normal people with driving license and 15 patients with thoracic or lumbar spinal cord injury who had driving experience. 5 driving skills were measured (average speed, steering stability, centerline violation, traffic signal violation, and time taken in driving) in various road conditions. The normal participants manipulated the gas pedal and the brake by their foot while the patients did with their hands. After they finished to drive the whole course, they answered the questions ("How realistic the driving simulator seems to you" and "How much your fear reduced")
Results: 1) Four driving skills measured between two groups (normal vs. handicapped) were not significantly different (p＞0.05). 2) In 4 kinds (start road, speed limit road, sharp curve road and left turn) of the road conditions, the average speed of the patients group was significantly different from the normal group (p＜0.05). 3) Eleven patients (73%) reported that their driving fear was reduced and the score of "how realistic" question was 51.5% in average.
Conclusion: This developed driving simulator will be able to be used for one of the programs for evaluating and training the driving skill of the handicapped and need to enhance the reality of driving simulator. (J Korean Acad Rehab Med 2002; 26: 311-315)
