To determine if there is muscle mass reduction in patients with ankylosing spondylitis (AS) compared to the general population and to examine the relationship between skeletal muscle mass, quality of life (QOL), strength, and mobility in patients with AS.
A total of 30 AS patients were enrolled in this study. Skeletal muscle mass was measured by bioelectrical impedance analysis, and it was expressed as the skeletal muscle mass index (SMI). QOL was assessed using the EuroQOL (EQ-5D). To measure mobility, the modified Schöber test and chest expansion test were used. To measure grip strength as a measure of muscle strength, we used the hydraulic hand dynamometer. Additionally, we divided the patients into two groups according to the degree of X-ray finding and compared the differences between the two groups.
There was no significant reduction in skeletal muscle mass in patients with AS compared to the general population. Also, there was no significant correlation between SMI and QOL. On the other hand, there was a significant positive correlation between SMI and mobility, and grip strength. A significant positive correlation was found between mobility and QOL. Additionally, there was a statistically significant difference in mobility between the two groups according to the degree of X-ray finding.
Maintaining muscle mass in AS patients may not be helpful for improving QOL, but it may contribute to achieving adequate mobility and strength.

To identify the effects of overactive bladder (OAB) symptoms on the health-related quality of life (HRQOL) in stroke patients since OAB symptoms are common in such patients, but their effects on stroke rehabilitation over time are unclear.
This study included 30 post-acute stroke patients who had been admitted for rehabilitation treatments. All participants completed a questionnaire evaluating urinary symptoms, including the Overactive Bladder Symptom Score (OABSS) and general HRQOL with a Short-Form 36 (SF-36) health survey. We assessed their performance in terms of the Function Ambulation Category, Modified Rankin Scale (MRS), Modified Barthel Index, and Mini-Mental State Examination (MMSE). All assessments were carried out twice at baseline and at 3 months. We divided patients into an OAB and non-OAB group with OABSS. A correlation analysis and multivariate regression were then performed.
All performance scales showed an improvement over 3 months in the non-OAB group (n=18; p<0.02), but, MRS and MMSE scores did not improve significantly in the OAB group (n=12) (p=0.15 and p=0.20, respectively). In the OAB group, the vitality and mental health scores significantly decreased over 3 months (p=0.011 and p=0,041, respectively), and the mental component summary (MCS) score showed a marginal decrease over 3 months (p=0.05). A multivariate regression analysis revealed that OAB symptoms were negatively correlated with the 3 months MCS score (B=−8.15, p=0.034).
These results indicated that OAB symptoms could have negative effects on HRQOL and performance in patients suffering from a stroke.

To evaluate the reliability of the practical life space in post-stroke patients using the Korean version of the Life-Space Assessment (K-LSA) questionnaire and to assess the relationships between the K-LSA and physical function, daily activity, quality of life, and post-stroke depression.
The LSA questionnaire was translated into Korean, and the translated version was authorized by the author of the LSA questionnaire. In a cross-sectional study, the performance of the K-LSA was evaluated in 34 stroke patients (20 males and 14 females; mean age 65.11±2.39 years) who were receiving physical and occupational therapy at the outpatient clinic in the rehabilitation medicine department of a university medical center at the time of evaluation. Performances were assessed twice by one examiner at a 2-week interval to test the reliability. The patients were evaluated using the Functional Ambulation Category (FAC) scale, Functional Independence Measure (FIM) scale, and mobility subscale of the FIM to assess their relationships with the K-LSA. They were also evaluated using the EuroQol 5 Dimensions questionnaire (EQ-5D) and Geriatric Depression Scale (GDS) to determine the relationship with quality of life and post-stroke depression.
Test-retest reliability at the first (62.20±32.14) and second (63.15±32.22) assessment was 0.993 (p<0.01). The K-LSA showed significant correlations with the FAC (r=0.848, p<0.01), FIM (r=0.765, p<0.01), mobility category of the FIM (r=0.764, p<0.01), GDS (r=-0.657, p<0.01), and EQ-5D (r=0.506, p<0.01).
This study suggests that the practical life space of post-stroke patients, assessed by the K-LSA, has a significant correlation with patients' functional mobility, independence in daily activity, quality of life, and depression.

To evaluate the association between clinical and socio-demographic status and health-related quality of life (HR-QoL) in stroke survivors age 40 and older in the Korean population.
The relationship between stroke and HR-QoL was investigated using data from the Korea National Health and Nutrition Examination Survey (KNHANES), conducted from 2007–2012. The total number of respondents was 24,050 and 757 stroke survivors were included. Specifically, we investigated factors associated with the lowering of HR-QoL in a group of Korean adult stroke patients age 40 and older after adjusting for socio-demographic factors, anthropometric measurements, and clinical comorbidities. Adjusted effects of covariates on EuroQol-visual analog scales (EQ-VAS) scores were estimated with a complex-samples general linear model and multivariate-adjusted odds ratios of the lowest quintile versus highest quintile of the EQ-VAS scores in the stroke group were estimated with a complex-samples logistic regression model.
Socio-demographic, anthropometric factors, and clinical comorbidities significantly differed between the stroke and non-stroke groups, except regarding gender and residential area. The EQ-VAS was significantly lower in the stroke than non-stroke group. Anxiety/depression problems significantly lowered EQ-VAS, as did low education level, smoking, mobility and usual activities problems. Also, aging in 1-year increments and cardiovascular disease had a significant effect on lower EQ-VAS in stroke survivors.
People with a stroke have significantly lower HR-QoL than healthy subjects. Therefore, managing depression, smoking, or cardiovascular disease and maintenance of physical function may be priority goals in improving HR-QoL after a stroke.

To explore and determine the reorganizational changes in the cortical neural circuits associated with pruritis, this study was undertaken to compare the electroencephalography (EEG) changes in burn patients having primary symptoms of chronic itching (pruritis) and their paired healthy subjects.
Eight subjects were recruited for this exploratory pilot study: 4 patients with pruritus after burn injury matched by gender and age with 4 healthy subjects. EEG recordings were analyzed for absolute alpha, low beta, high beta, and theta power for both groups.
The mean age of the burn patients was 41.75 years; while the mean age for the matched healthy subjects was 41.5 years. All subjects were male. A decreased alpha activity was observed in the occipital channels (0.82 vs. 1.4; p=0.01) and a decreased low beta activity in the frontal area (0.22 vs. 0.4; p=0.049) in eyes closed conditions. An overall decreased theta trend was observed in both the eyes open and eyes closed conditions in burn patients, compared to healthy individuals.
This preliminary study presents initial evidence that chronic pruritus in burn subjects may be associated with brain reorganizational changes at the cortical level characterized by an EEG pattern.

To compare the disability level of colorectal cancer survivors with and without stoma by using the Korean version of the 12-item, interview-administered World Health Organization Disability Assessment Schedule 2.0 (Korean version of WHODAS 2.0).
This is a multicenter (five tertiary university hospitals and the Korea Ostomy Association) and cross-sectional survey. Colorectal cancer survivors with and without stoma were interviewed. Survey measured disability level using the Korean version of WHODAS 2.0 and health-related quality of life using the SF-36.
A significant difference was observed between patients with and without a stoma in two subdomains: getting around (31.1 vs. 20.3; p=0.013) and participation in society (32.3 vs. 22.2; p=0.028). After adjusting for age, gender, and time since surgery, having a stoma was associated with severe to extreme disabilities in participation (OR=2.72, p=0.045). The Korean version of WHODAS 2.0 showed satisfactory internal consistency (r=0.96) and convergent validity.
Patients with stoma participated less in society than those without stoma. The Korean version of WHODAS 2.0 is a reliable and valid instrument for measuring disability in Korean colorectal cancer patients.

To establish the reliability and validity the Korean version of the Stroke Impact Scale (K-SIS) 3.0.
A total of 70 post-stroke patients were enrolled. All subjects were evaluated for general characteristics, Mini-Mental State Examination (MMSE), the National Institutes of Health Stroke Scale (NIHSS), Modified Barthel Index, Hospital Anxiety and Depression Scale (HADS). The SF-36 and K-SIS 3.0 assessed their health-related quality of life. Statistical analysis after evaluation, determined the reliability and validity of the K-SIS 3.0.
A total of 70 patients (mean age, 54.97 years) participated in this study. Internal consistency of the SIS 3.0 (Cronbach's alpha) was obtained, and all domains had good co-efficiency, with threshold above 0.70. Test-retest reliability of SIS 3.0 required correlation (Spearman's rho) of the same domain scores obtained on the first and second assessments. Results were above 0.5, with the exception of social participation and mobility. Concurrent validity of K-SIS 3.0 was assessed using the SF-36, and other scales with the same or similar domains. Each domain of K-SIS 3.0 had a positive correlation with corresponding similar domain of SF-36 and other scales (HADS, MMSE, and NIHSS).
The newly developed K-SIS 3.0 showed high inter-intra reliability and test-retest reliabilities, together with high concurrent validity with the original and various other scales, for patients with stroke. K-SIS 3.0 can therefore be used for stroke patients, to assess their health-related quality of life and treatment efficacy.

To evaluate the level of health-related quality of life (HRQoL), life satisfaction, and their present awareness of cardiac rehabilitation (CR) program in people with cardiovascular diseases.
A questionnaire survey was completed by 53 patients (mean age, 65.7±11.6 years; 33 men and 20 women) with unstable angina, myocardial infarction, or heart failure. The questionnaire included the Medical Outcome Study 36-item Short-Form Health Survey (MOS SF-36), life domain satisfaction measure (LDSM), and the awareness and degree of using CR program.
The average scores of physical component summary (PCS) and mental component summary (MCS) were 47.7±18.5 and 56.5±19.5, respectively. There were significant differences in physical role (F=4.2, p=0.02), vitality (F=10.7, p<0.001), mental health (F=15.9, p<0.001), PCS (F=3.6, p=0.034), and MCS (F=11.9, p<0.001) between disease types. The average LDSM score was 4.7±1.5. Age and disease duration were negatively correlated with multiple HRQoL areas (p<0.05). Monthly income, ejection fraction, and LDSM were positively correlated with several MOS SF-36 factors (p<0.05). However, the number of modifiable risk factors had no significant correlation with medication. Thirty-seven subjects (69.8%) answered that they had not previously heard about CR program. Seventeen patients (32.1%) reported that they were actively participating in CR program. Most people said that a reasonable cost of CR was less than 100,000 Korean won per month.
CR should focus on improving the physical components of quality of life. In addition, physicians should actively promote CR to cardiovascular disease patients to expand the reach of CR program.

To evaluate the effect of hospital-based cardiac rehabilitation (CR) on quality of life (QOL) and physical ability in patients with myocardial infarction (MI).
Patients with MI who were referred to the Cardiac Health and Rehabilitation Center 2 weeks after percutaneous coronary intervention were divided into CR and non-CR groups. The CR group performed supervised exercises 3 times a week for 2 months. QOL assessment, using the 36-item Short-Form Health Survey (SF-36) and physical ability evaluation were performed at the beginning and end of CR.
The CR group demonstrated statistically significant improvements in physical functioning (PF), physical role functioning (RP), bodily pain (BP), general health perceptions (GH), vitality (VT), social role functioning (SF), emotional role functioning (RE), mental health (MH), physical component summary (PCS), and mental component summary (MCS). The non-CR group showed improvement in RP. Secondary outcomes, including resting heart rate (RHR), maximal oxygen consumption (VO2max), metabolic equivalent of task (MET), maximal exercise time (ETmax), stage 3 Borg rating of perceived exertion (3RPE), maximal Borg rating of perceived exertion (RPEmax), and stage 3 rate pressure product (3RPP), improved in the CR group. The non-CR group showed improvements in VO2max, MET, ETmax, and 3RPE. There were significant differences in improvements in PF, RP, BP, VT, SF, MH, MCS, RHR, VO2max, MET, ETmax, 3RPE, and 3RPP between the two groups.
Male patients with MI demonstrated improvements in QOL and physical ability following hospital-based CR; the impact on the mental component was greater than that on the physical component.

To investigate the efficacy of systemic pulmonary rehabilitation (PR) after lung resection in patients with lung cancer.
Forty-one patients undergoing lung resection were enrolled and classified into the experimental (n=31) and control groups (n=10). The experimental group underwent post-operative systemic PR which was conducted 30 min/day on every hospitalization day by an expert physical therapist. The control group received the same education about the PR exercises and were encouraged to self-exercise without supervision of the physical therapist. The PR group was taught a self-PR program and feedback was provided regularly until 6 months after surgery. We conducted pulmonary function testing (PFT) and used a visual analog scale (VAS) to evaluate pain, and the modified Borg Dyspnea Scale (mBS) to measure perceived respiratory exertion shortly before and 2 weeks, 1, 3, and 6 months after surgery.
A significant improvement on the VAS was observed in patients who received systemic PR >3 months. Significant improvements in forced vital capacity (FVC) and mBS score were observed in patients who received systemic PR >6 months (p<0.05). Other PFT results were not different compared with those in the control group.
Patients who received lung resection suffered a significant decline in functional reserve and increases in pain and subjective dyspnea deteriorating quality of life (QoL). Systemic PR supervised by a therapist helped improve reduced pulmonary FVC and QoL and minimized discomfort during the postoperative periods in patients who underwent lung resection.

To investigate the changing patterns of edema, quality of life (QOL), and patient-satisfaction after complex decongestive therapy (CDT) in three trajectories: arm lymphedema (AL), secondary leg lymphedema (LL) and primary leg lymphedema (PL).
Candidates for AL (n=35), LL (n=35) and PL (n=14) were identified from prospective databases. The patients were treated with CDT for 2 weeks, and lymphedema volume was measured before and immediately following the therapy. Patients then self-administered home therapy for 3 months and presented for a follow-up visit. The Korean version of Short Form-36 (SF-36) was used to assess QOL, and we administered a study-specific satisfaction survey.
There was no significant difference in the volume reductions between the 3 groups. There were no significant differences in all of the measures between PL and LL. Overall initial QOL was significantly lower in patients with LL than in patients with AL. SF-36 scores post-CDT did not differ significantly between AL and LL. Clinically significant differences were noted between AL and LL in the mean values of the satisfaction survey.
AL, LL, and PL may have different longitudinal courses. We suggest that lower extremity lymphedema patients present more favorable outcomes after CDT with respect to QOL and satisfaction than upper extremity lymphedema patients. Clinicians should approach patients with different therapeutic considerations specific to each type or region of lymphedema before using CDT in clinical practice.

To investigate the effects of glenohumeral internal rotation deficit (GIRD) on the isokinetic strength, body pain, and the quality of life in male high school baseball players of Korea.
Fifty-six male high school baseball players were divided into either group A (GIRD≥20°, n=12) or group B (GIRD<20°, n=44). The range of motion in the shoulder and the isokinetic strength were measured. Questionnaires were administered regarding the body pain location by using the visual analogue scale, and the quality of life was measured by using the SF-36 Form.
All subjects had increased external rotation range of motion and decreased internal rotation in the throwing shoulder. The incidence of GIRD (≥20°) was 21.43% in the present study. In the isokinetic strength test, a significantly weaker muscular state at an angular velocity of 180°/s was observed in group A, compared to group B. For the comparison of the pain, the frequency of shoulder pain was higher (33.93%) than other body pain, among the study subjects.
GIRD is one of the main risk factors of glenohumeral joint damage, and it is correlated with reduced isokinetic strength and quality of life. High school baseball players will need appropriate shoulder rehabilitation programs for the improvement in their quality of life and performance.

To evaluate the degree to which the paralysis of a dominant hand affects quality of life (QOL) in patients with subacute stroke.
We recruited 75 patients with subacute hemiplegic stroke. Patients were divided into two groups according to the location of the lesion and the side of the dominant hand. Group 1 consisted of patients whose strokes affected the dominant hand (i.e., right hemiplegia and right dominant hand or left hemiplegia and left dominant hand). Group 2 consisted of patients whose strokes affected the non-dominant hand (i.e., left hemiplegia and right dominant hand or right hemiplegia and left dominant hand). The primary outcome measure was the Short-Form 36-Item Health Survey (SF-36), which was used to evaluate health-related QOL. Secondary outcomes were scores on the Modified Barthel Index (MBI) and Beck Depression Inventory (BDI).
We did not find any statistically significant differences between the groups in any SF-36 domain including the summaries of physical and mental component. Similarly, the MBI and BDI scores were not significantly different between the groups.
The effect of paralysis on the dominant hand and QOL in patients with subacute stroke was not significantly different from the effect of paralysis on the non-dominant hand.

To investigate the relationships between spinal mobility, pulmonary function, structural change of the spine, pain, fatigue, and quality of life (QOL) in patients with ankylosing spondylitis (AS).
Thirty-six patients with AS were recruited. Their spinal mobility was examined through seven physical tests: modified Schober test, lateral bending, chest expansion, occiput to wall, finger to ground, bimalleolar distance, and range of motion (ROM) of the spine. Pulmonary Function Test (PFT) was performed using a spirometer, and vertebral squaring was evaluated through the modified Stoke Ankylosing Spondylitis Spinal Score (mSASSS). QOL, disease activity, functional capacity, and fatigue were evaluated by SF-36 Health Survey (SF-36), the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), the Bath Ankylosing Spondylitis Functional Index (BASFI), and the Multidimensional Assessment of Fatigue (MAF) scale, respectively. Perceived physical condition and degree of pain were assessed using 10 cm visual analogue scale.
Participants showed reduced spinal mobility, which was negatively correlated with mSASSS. PFT results showed reduced forced expiratory volume in one second (FEV1) and forced vital capacity (FVC) and increased FEV1/FVC. Reduced FEV1 and FVC showed positive correlations with reduced spinal mobility and a negative relationship with mSASSS. Perceived physical condition and degree of pain were both significantly related to the SF-36, BASDAI, BASFI, and MAF scores.
This study shows that both reduced spinal mobility and radiographic changes in the vertebral body may have a predictive value for pulmonary impairment in patients with AS. Likewise, pain and perceived physical condition may play an important role in the QOL, functional capacity, and fatigue level of these patients.

To translate the MD Anderson Dysphagia Inventory (MDADI) which is a self-administered questionnaire that assesses effect of dysphagia on the quality of life for patients with head and neck cancer, into Korean and to verify the validity and reliability of the Korean version of MDADI.
We performed 6 steps for the cross-cultural adaptation which consisted of translation, synthesis, back translation, review by an expert committee, cognitive debriefing, and final proof reading. A total of 34 dysphagia patients with head and neck cancers from Seoul National University Hospital answered the translated version of the questionnaire for the pre-testing. The patients answered the same questionnaire 2 weeks later to verify the test-retest reliability.
One patient was excluded at second survey because he changed his feeding strategy. Overall, 33 patients completed the study. Linguistic validations were achieved by each step of cross-cultural adaptation. We gathered statistically strong construct validity (Spearman rho for subdomain scores to total score correlation range from 0.852 to 0.927), internal consistency for subdomains (Cronbach's alpha coefficients range from 0.785 to 0.889) and test-retest reliability (intra-class correlation coefficient range from 0.820 to 0.955)
The Korean version of the MDADI achieved linguistic validations and demonstrated good construct validity and reliability. It can be a useful tool for screening and treatment planning for the dysphagia of patients with head and neck cancers.

To evaluate the effect of complex decongestive physiotherapy (CDPT) on malignant lymphedema patients.
Patients (n=22) with malignant lymphedema of the upper or the lower limb were assigned to this study. CDPT without manual lymphatic drainage (MLD) was used five times per week for two weeks. The main outcome measurements included measurement of the circumference of the limb (proximal, distal, and total) to assess volume changes. We also employed the visual analog scale (VAS) to evaluate pain, and the short form-36 version 2 questionnaire (SF-36) to assess quality of life (QOL). All items were assessed pre and post-treatment for each patient.
There was a statistically significant difference in the volume change of the upper limbs (3.7%, p=0.001) and the lower limbs (10.9%, p=0.001). A 1.5 point reduction on the ten-point VAS was noted after CDPT. The scores on the physical and the mental components of the SF-36 showed statistical improvement after treatment (p=0.006, p=0.001, respectively).
These results suggest that all components of the CDPT program except MLD are helpful in treating malignant lymphedema in terms of pain reduction and reduction of the volume of the affected upper or lower limb. This treatment regimen also has positive effects on QOL.

To determine the associating factors of fear of falling (FOF) and the correlations between FOF and quality of life (QOL) on subacute stroke patients in Korea.
Fifty hemiplegic subacute stroke patients in our clinic were recruited. We directly asked patients with their fear of falling and interviewed them with the Korean version of falls efficacy scale-international (KFES-I). We divided the participants into two groups; with FOF and without FOF. We compared these groups with the strength of hemiplegic hip abductor, knee extensor, ankle plantar flexor, functional ambulation category (FAC) scale, stroke specific quality of life (SSQOL), and hospital anxiety depression scale (HADS).
Thirty-four participants were enrolled, and more than half of the patients with subacute stroke had FOF. We compared the patients with and without FOF. According to the results, FOF was associated with the strength of hemiplegic hip abductor, knee extensor and ankle plantar flexor, FAC, total SSQOL, and domains (energy, mobility, self care, upper extremity function) of SSQOL (p<0.05). FOF was also associated with the anxiety score of HADS (p<0.05). KFES-I had a significant negative correlation with the strength of hemiplegic hip abductor, knee extensor and ankle plantar flexor, FAC, total SSQOL, and domains (energy, mobility, self care, upper extremity function) of SSQOL (p<0.01).
The FOF was associated with not only QOL but also with the physical and psychological factors, and in particular, anxiety. Therefore, further concerns about FOF in subacute stroke patients might be required.

To investigate the relationship between severity of peripheral polyneuropathy (PPN) and degree of depression and quality of life in chronic renal failure (CRF) patients on hemodialysis (HD).
Forty seven chronic renal failure patients on hemodialysis were recruited (22 male, 25 female, mean age of 63.17±12.52) and etiology, disease duration, hemodialysis duration, creatinine and hemoglobin were recorded. Motor and sensory nerve conduction studies were carried out on bilateral median, ulnar, tibial and peroneal nerves for diagnosis of polyneuropathy according to our laboratory criteria. The Korean version of Beck depression inventory (BDI) questionnaire translated into Korean for diagnosis of depression, and Korean version of Short Form 36 health survey (SF-36) questionnaire for measurement of general health level were measured in those diagnosed with uremic PPN.
Out of 52 patients, 47 were diagnosed with polyneuropathy and mean score for BDI was 18.49±9.18. Mean scores for each of Mental Component Summary (MCS) and Physical Component Summary (PCS) of SF-36 were 50.84±15.42 and 47.41±18.68. The correlation between the scores and polyneuropathy were analyzed by Pearson coefficient. The MCS score was the significant (p<0.05) correlation parameter with depression (R=-0.635) and the PCS score was the only parameter with a significant (p<0.05) correlation with polyneuropathy (R=-0.340).
Uremic polyneuropathy is commonly observed in chronic renal failure patients on hemodialysis. Depression in CRF with uremic PPN is affected by psychological factors other than the PPN itself.

To evaluate quality of life (QOL), upper extremity function and the effect of lymphedema treatment in patients with breast cancer related lymphedema.
The basic data comprised medical records (detailing age, sex, dominant side, location of tumor, cancer stage, operation record, cancer treatment and limb circumferences) and questionnaires (lymphedema duration, satisfaction, self-massage). Further to this, we measured upper extremity function and QOL, administered the DASH (Disabilities of Arm Shoulder and Hand outcome measure) and used the EORTC (European Organization for Research and Treatment of Cancer)-QLQ-C30 and the EORTC-QLQ-Br23. Results of these were calculated as main outcome variables.
The questionnaire responses and arm circumferences of 59 patients with breast cancer related lymphedema were analyzed. In the DASH questionnaire, it was found that the older the lymphedema patient was, the lower their upper extremity function. On the EORTC-QLQ, patients with metastasis had significantly lower scores in physical functioning and role functioning. In terms of upper extremity circumference, there was a significant upper extremity size reduction after lymphedema treatment.
There were several dissociations between some subscales of quality of life questionnaires and those of upper extremity functions. Upper extremity function was correlated with the age of breast cancer patients and QOL was influenced by M-stage. Lymphedema treatment was found to be effective in reducing edema in patients with breast cancer related lymphedema.
