OBJECTIVE: This study was carried out to help the comprehensive rehabilitation of cervical cord injuries by measuring propulsion force and endurance on their wheelchair hand- rims, predicting the differences between neurological levels and analysing the factors which contributed to maintain the wheelchair propulsion force. METHOD: The BTE work simulator was used on 17 cervical cord injuries to test the force and endurance during wheel chair propulsion. The 141 large wheel of BTE work simulator and standard wheelchair which was removed handrims was used for simulating wheelchair propulsion. Wilcoxon rank sum test was used to compare force and endurance among the groups. RESULTS: The wheelchair propulsion force and endurance showed significant differences between neurological levels and types of the life style. The lower the level, the higher the strength and endurance (p<0.001). The wheelchair propulsion force of cervical cord injuries showed statistically significant differences between those with and without jobs (p<0.05). The outdoor wheelchair users and wheelchair propulsion exercise group showed significantly high maximum isometric strengths compared to the indoor users and the only ROM exercise group, respectively (p<0.05). CONCLUSION: During the rehabilitation period cervical cord injured persons need the wheelchair propulsion exercise using BTE work simulator to improve the quality of life.

OBJECTIVE: To evaluate the force, endurance and influencing factors for wheelchair propulsion in paraplegics using BTE work simulator, and to find out a better method improving fitness levels for the paraplegics. METHOD: Seventeen paraplegic men were enrolled for the study. Isometirc and isotonic strength and dynamic endurance levels for wheelchair propulsion were measured using BTE work simulator. Neurological and demographical characteristics of patients were collected by personal interviews and direct examinations. RESULT: The spinal cord injured level showed a significant correlation with dynamic endurance (r=0.503, p<0.05) but not with the isometric and isotonic strength. The total duration of wheelchair use showed a significant correlation with the isotonic strength (r=0.497, p<0.05), but not with the isometric strength and dynamic endurance. The age and outdoor activities or exercise time during one week showed no significant correlation. CONCLUSION: Spinal cord injured level positively correlated with dynamic endurance. Both cardiorespiratory effect and trunk balance may influence this correlation. The total duration of wheelchair use wasn't correlate with dynamic endurnace. It seems to be more advisable trunk balance training goes with dynamic endurance training in rehabilitation program.

OBJECTIVE: To assess the effects of backrest inclination of a wheelchair on buttock pressures in spinal cord injured (SCI) patients and normal subjects. METHOD: The participants were 22 healthy subjects and 22 SCI patients. Buttock pressures of the participants were measured by a Tekscan(R) pressure sensing mat and software while they were sitting in a reclining wheelchair. Buttock pressures were recorded for 90degrees, 100degrees, 110degrees, 120degrees and 130degrees seat-to-back angles at the ischial tuberosity (IT) and sacrococcygeal (SC) areas. Recordings were made at each angle over four seconds at a sampling rate of 10 Hz. RESULTS: The side-to-side buttock pressure differences in the IT area for the SCI patients was significantly greater than for the normal subjects. There was no significant difference between the SCI patients and the normal subjects in the buttock pressure change pattern of the IT area. Significant increases in pressure on the SC area were found as backrest inclination angle was changed to 90degrees, 100degrees and 110degrees in the normal subjects, but no significant differences were found in the SCI patients. CONCLUSION: Most of the SCI patients have freeform posture in wheelchairs, and this leads to an uneven distribution of buttock pressure. In the SCI patients, the peak pressure in the IT area reduced as the backrest angle was increased, but peak pressure at the SC area remained relatively unchanged. To reduce buttock pressure and prevent pressure ulcers and enhance ulcer healing, it can be helpful for tetraplegic patients, to have wheelchair seat-to-back angles above 120degrees.

OBJECTIVE: To examine changes in seat-interface pressure in wheelchair seated spinal cord injured patients. METHOD: Twenty-six spinal cord injured patients, who were motor complete tetraplegic and paraplegic patients, were included in this study. After 5 cm air-filled cushion (ROHO(R)) was placed on their own wheelchair seat, patients were seated on wheelchair with neutral position for sixty minutes. The interface pressure and contact area of buttock was measured every 5 minutes. RESULTS: Significant increases of interface pressure were found in maximal and mean interface pressure during 0 to 25 minutes of sitting (p<0.05). An increased tendency of contact area of buttock was observed during sitting time but it was not significant. CONCLUSION: There were no significant changes of interface pressure after 25 minutes of sitting in spinal cord injured patients. Therefore, twenty-five minutes may be a reasonable sitting time before interface pressure is recorded.

OBJECTIVE: To investigate the shoulder disease patterns for the table-tennis (TT) and archery (AR) wheelchair athletes via ultrasonographic evaluations. METHODS: A total of 35 wheelchair athletes were enrolled, made up of groups of TT (n=19) and AR (n=16) athletes. They were all paraplegic patients and were investigated for their wheelchair usage duration, careers as sports players, weekly training times, the Wheelchair User's Shoulder Pain Index (WUSPI) scores and ultrasonographic evaluation. Shoulders were divided into playing arm of TT, non-playing arm of TT, bow-arm of AR, and draw arm of AR athletes. Shoulder diseases were classified into five entities of subscapularis tendinopathy, supraspinatus tendinopathy, infraspinatus tendinopathy, biceps long head tendinopathy, and subacromial-subdeltoid bursitis. The pattern of shoulder diseases were compared between the two groups using the Mann-Whitney and the chi-square tests RESULTS: WSUPI did not significantly correlate with age, wheelchair usage duration, career as players or weekly training times for all the wheelchair athletes. For the non-playing arm of TT athletes, there was a high percentage of subscapularis (45.5%) and supraspinatus (40.9%) tendinopathy. The percentage of subacromial-subdeltoid bursitis showed a tendency to be present in the playing arm of TT athletes (20.0%) compared with their non-playing arm (4.5%), even though this was not statistically significant. Biceps long head tendinopathy was the most common disease of the shoulder in the draw arm of AR athletes, and the difference was significant when compared to the non-playing arm of TT athletes (p<0.05). CONCLUSION: There was a high percentage of subscapularis and supraspinatus tendinopathy cases for the non-playing arm of TT wheelchair athletes, and a high percentage of biceps long head tendinopathy for the draw arm for the AR wheelchair athletes. Consideration of the biomechanical properties of each sport may be needed to tailor specific training for wheelchair athletes.

This paper reports a rare case of a lumbosacral dislocation associated with symphysis pubis separation and cauda equina syndrome. A 39-year-old male who diagnosed traumatic lumbosacral dislocation underwent an open reduction without fusion. After an open reduction and internal fixation of a symphysis pubis separation, a missed lumbosacral dislocation was diagnosed and an open reduction was performed without fusion. Due to the symphysis pubis separation, the patient was not allowed weight bearing for 3 months, which then began from wheel chair ambulation. At the 6-month follow up evaluation, there was no back pain but the patient reported mild S1 nerve root sensory symptoms. Lumbosacral dislocation is common in high energy polytrauma patients and can be misdiagnosed. However, prompt reduction without fusion is a good alternative treatment.

OBJECTIVES: The purpose of this study is to examine relationship between an amount of key tasks and job satisfaction among caregivers and nurses in elderly care facilities. METHODS: Questionnaires were mailed to the caring staff of elderly care facilities. After data collection (return rate 70%), information about work situations and health conditions were analyzed among 325 female workers, who were classified to 4 groups as follows; (1) caregivers under 40 years of age (2) caregivers of 40 years or over (3) nurses under 40 years of age (4) nurses of 40 years or over. RESULTS: Mean ages and length of career in caring sector were 37.2 +/- 12.2 yr and 4.5 +/- 3.0 yr for caregivers and 41.6 +/- 9.2 yr and 16.8 +/- 8.9 yr for nurses, respectively. A larger amount of care services were done on average by workers being dissatisfied with their job than by the satisfied workers in each of the 4 groups. The dissatisfied caregivers under 40 years showed significantly higher frequencies (as ratios of 1.4 - 2 to 1) in several care services such as "helping with showers or baths", "helping with eating", "changing diapers", "moving caretakers from bed or chair to wheelchair or vice versa", as compared with the satisfied caregivers under 40 years. Similarly, the 40 plus dissatisfied caregivers helped caretakers sit up in bed significantly more frequently. For nurses, on the other hand, "changing diapers" was found as the only service with a significant difference in frequency between the dissatisfied and the satisfied, but that was limited in the 40 plus age group. A frequency of "changing diapers" was associated with an increase in the risk of job dissatisfaction. CONCLUSIONS: These results suggested that an appropriate amount of each key task in elderly care facilities should be set to prevent staff\'s dissatisfaction with their job from growing excessively.

The purpose of this study was to investigate the effect of wheelchair ergometer training on spinal cord-injured paraplegics. Eleven male paraplegics with a mean age of 30.9 years (range, 20 to 49 years) participated in the wheelchair ergometer training for the period of 5 weeks. The mean peak heart rate, the mean peak systolic blood pressure and the mean time required for 100m wheelchair propelling at resistance level 1 were significantly decreased at the end of 5 weeks of training as compared with those at pre-training. There was no statistically significant difference in pulmonary function test at pre- and post-training. The peak torque of shoulder flexor and the total work of shoulder flexor and extensor at 180 degrees/sec after training were increased more significantly than those prior to the training. In accordance with the findings as revealed above, it is deemed that the endurance and strength of the upper body and the cardiac fitness for spinal cord-injured paraplegics may be improved by the wheelchair ergometer exercise

OBJECTIVE: To evaluate changes in activity of daily living before and after provision of electric-powered indoor/outdoor chair (EPIOC), discuss problems of current activities of daily living (ADL) evaluating tools for EPIOC users, and provide preliminary data to develop ADL evaluation tool for EPIOC user. METHODS: A total of 70 users who were prescribed EPIOC and had been using for more than 1 year were recruited in this study. Before and after provision of EPIOC, MBI and FIM scores were measured and a questionnaire consisting of six categories (general socioeconomic states, currently using state, whether EPIOC was helpful for social participation and occupational chances, psychiatric influences, self-reported degrees of independency, and barriers of using EPIOC) was used. RESULTS: No difference in MBI scores before and after provision of EPIOC was observed. However, the wheelchair ambulation category showed a significant difference. While motor FIM was not significantly different from MBI, FIM score were significantly (p<0.05) higher than MBI. For questions regarding social participation frequency, helpfulness of EPIOC on confidence, refreshing patients' emotions and self-reported degrees of independence, all of them showed positive responses. Especially, EPIOC users' self-reported degree of independency showed favorable results. There was discrepancy in MBI or FIM measured by physicians. CONCLUSION: Our study showed that there was a gap between the existing ADL evaluation tool and the ADL level that EPIOC users were actually feeling. Thus, it is necessary to develop an evaluation tool specifically for EPIOC.
