Objective: To examine the effects of various feedback system training programs on the walking ability of stroke patients. Method: Forty-four inpatients who were undergoing physical therapy in B hospital were divided into two groups of 20. Each group underwent two different feedback system training for 30 minutes each day, three times per week, for eight weeks from June to August of, 2015. The cadence, stride time, step time, step width, stride length, step length, st ance phase, and 10 m Walk Test were used to examine the patient's walking abilities. A repeated analysis of variance (ANOVA) was conducted to compare the differences bet ween these factors, before and after the training, within each group. In addition, an; independent t-test was conducted to compare the differences in the amounts of changes before, at 4, and 8 weeks after the training, between the two groups. Results: In the comparison within and between each group, both groups showed significant differences(p<.05) in the cadence, step time, stride length, step length, and 10 m WT before and after 8 weeks. Overall, the MFG group showed greater improvement when compared to the FG group(p<.05). Conclusion: In terms of efficient training, the mirror and feedback system training on the treadmill was more effective to improve a stroke patient's gait.

Objective: The purpose of this study was to investigate the maximum voluntary isometric(MVIC) of gluteus medius muscle determine if there are differences in these MVIC with respect to different position. Method: 30 healthy subjects with no known musculoskeletal disorders were recruited as the participants. The MVIC hip abduction at nine different position. Differences in MVIC in according with various condition were assessed by use of repeated one-way ANOVA. Differences surface and muscle contraction type were assessed by use of paired t-test. Results: Glureus medius muscle MVIC were significantly greater for hip abduction at angles of 0° and 25°than 45°, were significantly greater for ankle than knee area, and were significantly greater for eccentric contraction than concentric contraction. Conclusion: Hip abduction at angle of 0°and 25°, ankle, and eccentric contraction position may be effective in activating the gluteus medius muscle.

Objective: To study the effects of mirror therapy on upper extremity function, grip power, and activities of daily livings of patients with stroke. Method: Participants were 30 chronic stroke patients who were receiving occupational therapy in W Hospital located in Gangwon-do. Participants were divided into two groups, 15 patients each and mirror therapy and blocked mirror therapy training were applied respectively 8 weeks, for 20 minutes a session, 5 session per week. Before and after the intervention, upper extremity function, grip power, and ADLwere examined. ANCOVAs were conducted to examine of the amounts of changes between the groups. Paired t-test were conducted to compare upper extremity function, grip power, and ADL before and after the intervention within each group. Results: In the comparison between the two groups, upper extremity function and ADL of before and after the intervention showed significant increase in the study group than control group(p<.05). In both groups, difference of before and after intervention significantly increased(p<.05). Only grasp & lateral pinch among grip power result showed significant increase in the study group(p<.05). Conclusion: As a result of mirror therapy for stroke patients, results of upper extremity function, grip power, and ADL of the study group statistically increased compared to the control. We expect mirror therapy to be another possible intervention approach in body function improvement for people with stroke. However, further studies and proofs are needed to apply mirror therapy in occupational therapy clinical setting.

Objective: This study examined the effects of mirror therapy on stroke patients' recover y of lower extremity function, balance ability, mobility, and center of pressure (COP) mo vement. Method: Forty stroke patients were allocated randomly and equally to a mirror therapy group and a control group. They received physical, occupational, and speech therapies. T he mirror therapy group received training with a mirror reflecting the non-affected side and the control group without a mirror reflecting the non-affected side. Training was ap plied thirty minutes each time, five times per week, for 8 weeks. Fugl Meyer assessmen t of low extremity (FMLE), Korean version of Berg balance scale (K-BBS), functional g ait assessment (FGA), and gaitview to measure COP movement were used as measurem ent tools. Result: There was no significant difference in FMLE between the mirror therapy group and the control group, but the mirror therapy group saw significant improvements in KBBS, FGA, and COP relative to the control group (p<.05). Regarding comparis on within each group, the mirror therapy group's FMLE and COP(p<.05) and the group's K-BBS and FGA(p<.05) significantly improved. The control group's FMLE and K-BBS improve d during the eight weeks(p<.05) and FGA and COP saw no statistically significant impr ovements. Conclusion: Mirror therapy is considered an efficient training method to enhance stroke patients' mobility.

Objective: The purpose of this study was to restore the balance of the whole body and resolve cervical spine problems, such as cervical curve deformity, by applying cervico-lumbar exercises in cervical spine patients. Method: Twenty-seven patients with 5° or larger cervical curve deviations were selected from patients at T Hospital and were randomly divided into a cervical exercise group and a cervico-lumbar exercise group. The cervical curves, including the cervical lordotic angle, thoracic kypotic angle, lumbar lordotic angle, and Ferguson angle, of both groups were measured using X-rays. The values of body alignment, including the ear, acromion, great trochanter, lateral epicondyle of the knee joint, and malleous, were measured using dynamic posturography. Eight weeks after the measurements, both groups were re-measured to compare the results before and after the experiment. Paired t-tests and an ANCOVA were employed to analyze differences in the averages of the two groups and to perform a comparative analysis with the experimental phase. Results: The within-group comparison showed that both groups had statistically significant changes in the cervical lordotic angle before and after the experiment(p<.05). Regarding the values of body alignment, the control group showed no statistically significant changes in the ear, acromion, and great trochanter(p<.05), whereas the test group exhibited statistically significant changes in the same variables. Conclusion: In this study of cervical spine patients, the application of cervico-lumbar exercises was more effective than cervical exercises.

흉추 관절가동술이 만성요통환자의 통증, 장애지수 및 척추 운동성에 미치는 효과

본 연구는 만성통증환자를 대상으로 흉추 가동술과 윌리암 운동을 적용하여 통증, 장애지수 및 척추운동성에 대한 효과를 알아보고자 수행되었다. 대상자는 K병원에서 만성요통으로 치료를 받는 22명으로 선정하였으며, 흉추 가동술군 11명과 윌리암 운동군 11명으로 나누어 6주간 실시하였다. 대상자는 시각적 통증척도, 오스웨스트리 장애지수, 척추운동성 평가를 실시하였으며 자료 분석은 반복측정분산분석과 짝비교-t 검정을 실시하여 다음과 같은 결과를 얻었다. 윌리암 운동군에 비해 흉추 가동술군에서통증의 유의한 감소, 오스웨스트리 장애지수의 유의한 감소, 척추의 운동성의 유의한 증가를 확인하였다(p<05). 따라서 만성요통환자의 관리를 위해 흉추 가동술을 적용하는 것이 통증과 장애지수, 척추의 운동성에 효과가 있으며, 요통환자의 관리에 있어 흉추의 가동성을 확보하는 것이 필요하다고 생각한다.
