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.

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.
