목적 : 본 연구는 동작관찰 훈련이 만성 뇌졸중 환자의 목적 있는 활동 과제와 관련된 상지 운동기능에 미치는 영향 을 알아보고자 하였다. 연구방법 : 13명의 만성 뇌졸중 환자를 실험군과 대조군으로 무작위 선정하였다. 실험군은 동영상을 통해 목적 있는 활동 과제의 수행 동작을 관찰한 후 동작을 반복적으로 모방 연습하였고, 대조군은 전통적인 작업치료를 시행 하였다. 훈련은 주 3회, 회당 30분, 3주간 실시하였다. 상지 운동기능 평가는 울프운동기능과 장악력 및 파악력을 시행하였고, 각 군의 전후 차이는 윌콕슨 부호순위 검정(Wilcoxon signed-ranks test)과 두 군 간의 비교는 맨 휘트니 검정(Mann-whitney u test)으로 분석하였다. 결과 : 훈련 후, 대상자의 상지 운동기능은 두 군 간의 유의한 차이를 보였고, 특히 실험군은 훈련 후에 유의한 증진을 보였다. 실험군의 장악력과 외측집기는 훈련 후에 유의한 증진을 보였다. 결론 : 동영상을 통한 동작관찰은 같은 동작을 집중적이고 반복적으로 연습하는 전통적인 작업치료 접근보다 상지 운동기능 회복의 긍정적인 효과를 이끌어 주었다. 따라서 동작관찰 훈련을 작업치료 중재 유형의 한 전략으로 제안하고자 한다.

Abdominal muscle plays a crucial role in postural control and respiration control. However, thickness of abdominal muscle in the paretic side of a hemiplegic patient has not been reported in previous studies. The purpose of this research was to compare lateral abdominal muscle thickness between the nonparetic and paretic side in patients with chronic stroke using rehabilitative ultrasound imaging. Twenty two patients with chronic stroke participated in this study. Absolute thickness of transversus abdominis (TrA), internal oblique (IO) and external oblique (EO) was measured at the end of inspiration and expiration during quiet breathing, and relative thickness was calculated (thickness of each muscle as a percentage of total muscle thickness). Ultrasound imaging was recorded three times and the average value was determined for statistical analysis. Differences in absolute and relative lateral abdominal muscle thickness between the nonparetic and paretic side were assessed with paired t-tests. Absolute muscle thickness of the paretic side TrA was thinner than that of the nonparetic side at the end of inspiration and expiration during quiet breathing. Relative muscle thickness of the paretic side TrA was thinner than the paretic side only at the end of expiration during quiet breathing (p>.05). Therefore, it is necessary to strength TrA in patients with chronic stroke during physical therapy intervention. Further study is needed whether physical therapy intervension will induce TrA thickness in patients with chronic stroke in prospective study design.

The purpose of this study was to investigate the effects of virtual reality (VR) therapy with compensation inhibition and feedback (CIF) on upper extremity function in chronic stroke patients. Seven chronic stroke patients participated in this study, which was a randomized controlled trial with a crossover design. Self upper extremity exercise, conservative VR therapy, and VR therapy with CIF were performed for one hour per session, 5 times per week, over a 3 week period. The main outcome measures involved range of motion (ROM) including shoulder, elbow, and wrist joints, a Manual Function Test (MFT), and a Motor Activity Log (MAL). Data were calculated as posttest and pretest changes in every session and were analyzed using Friedman and Wilcoxon signed-rank tests at p<.05. The results were as follows: 1) Statistically significant increase in ROM measurements of shoulder and elbow joints were seen with VR therapy with CIF compared to VR therapy and self upper extremity exercise (p<.05), whereas no significant increasing was noted for the wrist joint (p>.05). 2) Statistically significant increase in the MFT was seen with VR therapy with CIF compared with VR therapy and self upper extremity exercise (p<.05). 3) VR therapy with CIF also resulted in statistically significant increase in both activity of use (AOU) (p<.05) and quality of movement (QOM) (p<.05) on the MAL test when compared with VR therapy and self upper extremity exercise, respectively. In conclusion, VR therapy with CIF was more effective than conservative VR therapy and self upper extremity exercise in improving the upper extremity function in hemiplegic patients with chronic stroke.

The purpose of this study was to investigate the effects of a task-oriented approach on weight-bearing distribution and muscular activities of the paretic leg during sit-to-stand movement in 18 chronic stroke patients. Both groups were received neurodevelopmental treatment for 30 min/day and then the experimental group (=9) followed additional a task-oriented approach (sit-to stand training with controlled environment) and the control group (=9) followed a passive range of motion exercise for 15 min/day, five days/week, for four weeks. Weight-bearing distribution and muscular activities of the paretic leg during sit-to-stand movement were measured before and after four weeks of training. There was significantly improved weight-bearing distribution of the paretic leg during sit-to-stand movement in the experimental group compared with that of the control group after four weeks of training (p<.05). But electromyographic activities of the quadriceps and the tibialis anterior of the paretic leg were not significantly different (p>.05). Thus, it is necessary to apply a task-oriented approach to improve the weight-bearing distribution of the paretic leg during sit-to-stand movement in chronic stroke patients.

In this case report, we investigated the effects of robot-assisted gait therapy in a chronic stroke patient using motor assessment and gait analysis. A patient who suffered from the right hemiparesis following the left corona radiata and basal ganglia infarction received 30 minutes of robot-assisted gait therapy, 3 times a week for 4 weeks. Outcome was measured using Motoricity index(MI), Fugl-Meyer assessment(FMA), modified motor assessment scale(MMAS), isometric torque, body tissue composition, 10-meter gait speed and gait analysis. After robot-assisted gait therapy, the patient showed improvement in motor functions measured by MI, FMA, MMAS, isometric torque, skeletal muscle mass, 10-meter gait speed. In gait analysis, cadence, single support time, double support time, step length, walking speed improvement in after robot-assisted gait therapy. The results of this study showed that robot-assisted gait therapy is considered to facilitate locomotor recovery of the chronic hemiparetic stroke patient.

This study examined whether any changes by mental task types on postural control in chronic stroke persons. Sixteen chronic stroke persons (mean age=53.75 yr) and sixteen age-and gender-matched healthy controls (mean age=54.44 yr) took part in this study. Participants randomly performed three different tasks on the stable and unstable surfaces. The no mental task was to stand while holding a 100 g weight in each hand, the arithmetic task (mental task) was to perform a silent 1-backwards counting while standing and holding a 100 g weight in each hand, and the simple task (mental task) was to stand and hold with both hands a tray (200 g) on which a glass filled with water has been placed. Sway path and sway velocity of the center of pressure (COP) were measured to assess standing postural control by task performance using the force platform. According to the results, in stroke group, total sway path and total sway velocity of COP was significantly decreased during arithmetic and simple task compared to no mental task on the stable surface (p<.05), and sway path (anteroposterior AP, mediolateral ML) of COP, total and sway velocity (AP, ML, total) of COP was significantly decreased during arithmetic and simple task compared to no mental task on the unstable surface (p<.05). Especially, sway path (AP, total) of COP and sway velocity (AP, ML, total) of COP was significantly decreased under the simple task when compared to the arithmetic task on the unstable surface (p<.05). In healthy control group, sway path (AP, ML, total) of COP and sway velocity (AP, ML, total) of COP was significantly decreased during arithmetic and simple task compared to no mental task on the stable and unstable surface (p<.05), and sway path (AP, total) of COP and sway velocity (AP, ML, total) of COP was significantly decreased under the simple task when compared to the arithmetic task on the unstable surface (p<.05). In conclusion, the findings of this study showed that arithmetic and simple task improved standing postural control for chronic stroke patients and the type of arithmetic and simple tasks were critical factor that reduced standing postural sway in dual-task conditions. Future research should determine whether dual-task conditions, including simple task, would be effective as a training program for standing postural control of stroke patients.

This study aimed to evaluate the effect of a weekly circuit-group exercise program on functional performance, flexibility of the trunk and lower extremities, and balance in individuals with chronic stroke who are living in a community. Thirteen community-living individuals (eleven males and two females) with chronic stroke participated in this study. The group exercise program was set up as a weekly circuit application with four stations aiming to strengthen the muscles, increase endurance, improve flexibility, and enhance functional capacity. The average duration of a session was an hour, and the sessions were conducted once a week for six months for a total of 24 sessions. Assessments for functional performance, flexibility of the trunk and lower extremities and balance were conducted four times: before treatment, after one month of treatment, after four months of treatment, and after six months of treatment. There were significant improvements in functional performance and flexibility of the trunk and lower extremities in the given time frame. No significant improvement was observed in balance ability. The findings suggest that a weekly circuit-group exercise program has some benefits in terms of managing the physical symptoms of individuals with mobility problems after stroke. Therefore, this program can be adapted and employed as a community-based rehabilitation program for such patients. Further studies with various community-based treatments will be conducted to validate these findings.

The purpose of this study was to find any correlations among Postural Assessment Scale for Stroke (PASS), Modified Barthel Index (MBI), Tone Assessment Scale (TAS), Motor Assessment Scale-Gait (MAS-G), Fugl Meyer-Balance (FM-B), and to predict MBI from subscales of the PASS. The subjects were 41 stroke patients of the Korea National Rehabilitation Center in Seoul. The main outcome measures were postural control (PASS), gait (MAS-G), Balance (FM-B), Tone (TAS), ADL (MBI). The data was analyzed using the Pearson product correlation. PASS scale was used between other clinical and instrumental indexes, multiple stepwise regression analyses were performed to identify prognostic factors for ADL incline, and Cronbach's alpha coefficient was used to identify internal consistency on PASS scale. The results of this study areas follows: 1. The highest level was sitting without support, the lowest level was standing on paretic leg on PASS scale. The highest level was chair/bed transfer, the lowest level was bathing on MBI. 2. All items of the PASS, except postural tone were significantly correlated with Gait, Balance, MBI (p<.01), 3. The Internal Consistency (Cronbach's alpha coefficient=.85) was very high, indicating that the PASS is homogeneous and is likely to produce consistent response. Furthermore, the sums of maintaining position items and of changing-position items were strongly correlated (r=.64, p<.05) and there were significant correlations between sums of PASS, sums of maintaining position items (r=.87, p<.01), and changing-position items (r=.93, p<.01). 4. The standing without support of the PASS items was the strongest variance (R²=.85) of the predicting ADL function. These findings provide strong evidence of the predictive value of the postural control on gait, Balance, ADL function in stroke patients and to can provide a reference for the successful therapeutic program and more improved functional recovery.

The purpose of this study was to determine the consequence of resistance strengthening exercise on the hip flexor and extensor performed to improve functional mobility in stroke patients more than six months post stroke. Seventeen patients were randomized into two groups. Both groups received conventional physical therapy for six weeks. In addition, the experimental group performed eccentric resistance strengthening exercise in the hip flexor and extensor using an isokinetic dynamometer. The hip flexor and extensor strength, stair up and down mobility, timed get up and go (TUG), 10 m gait velocity, and functional reach were repeatedly measured at baseline, three weeks, and six weeks after treatment. The results were as follows: 1. The experimental group improved more remarkably in the hip flexor and extensor strength, stair up and down mobility, and the 10 m gait velocity after three weeks and six weeks of treatment (p<.05), 2. The control group improved significantly in the hip flexor and extensor strength, and 10 m gait velocity after three weeks of treatment (p<.05), 3. At each three and six week point, the experimental group made greater gains in hip flexor and extensor strength, stair up and down mobility, and 10 m gait velocity than the control group (p<.05). In conclusion, it is desirable to perform resistance strengthening exercises combined with conventional physical therapy to improve functional mobility in chronic stroke patients.

The purpose of this study was to investigate the effects of clinical characteristics of chronic stroke patients on physiological cost index (PCI) during walking. Fourteen stroke patients participated in this study. To investigate the clinical characteristics, Fugl-Meyer score (FMS), gait velocity (GV), muscle strength of the knee extensor, modified Ashworth scale (MAS) of ankle plantar flexor, devices, and gait patterns during walking were measured and analyzed. The results were as follows: Firstly, use of devices and high MAS of the ankle plantar flexor significantly increased PCI. Secondly, PCI was significantly correlated with the FMS and MAS of the ankle plantar flexor. In conclusion, inhibition of spasticity of the ankle plantar flexor is considered to reduce PCI during walking for chronic stroke patients.

Community-based group exercise programs for people with chronic stroke are relatively uncommon in Korea. In addition, it is currently not known whether a community-based group exercise program is effective or not. The purpose of this study was to evaluate an 8 week community-based functional exercise program for its effects on balance performance and occupational performance in persons with chronic stroke. Twenty-five community-dwelling individuals with stroke participated in this program. Outcome of the program was assessed by the Berg Balance Scale and the Canadian Occupational Performance Measure (COPM). The functional exercise program lasted for eight weeks, with a 1-hour program twice per week and it consisted of mobility, stability, balance, functional strength, and gait training. The subjects were trained by one physical therapist but were under one-to-one supervision from students. The data of sixteen individuals who scored more than 24 on the Mini-Mental State Examination (MMSE) were analyzed. There was a significant effect both in terms of the COPM Performance Score & the Satisfaction Score (p=.002) and with the Berg Balance Score (p=.001). It was found that a short-term community-based exercise program could improve both performance of activities and balance. Further, all subjects reported that they were satisfied with this program.

목적: 이 연구에서는 장애물 높이에 따른 만성 뇌졸중 환자의 장애물 보행 특성과 보상전략을 파악하였다. 방법: 이를 위해 두 가지 장애물 높이 조건(5cm와 15cm)에 따라 장애물 보행의 운동학적 특성을 정상인과 비교하였다. 구체적으로 장애물 보행 전 이륙 거리, 장애물 통과 시 장애물 통과 높이와 장애물 통과 후 착지 거리를 측정하 였다. 결과: 분석결과, 만성 뇌졸중 환자들은 정상인보다 보행 전 이륙 거리와 장애물 통과 후 착지 거리가 상대 적으로 짧은 것으로 나타났다. 또한, 뇌졸중 환자들은 정상인보다 장애물을 통과할 때 통과 높이가 높은 것으로 밝혀졌다. 이러한 보행 움직임 패턴은 두 가지 장애물 조건에서 모두 유사하게 나타났다. 결론: 이러한 결과는 뇌 졸중 환자들이 편측 마비로 인한 움직임 제약에 기인하는 것으로 판단된다. 또한, 신체적 장애로 인해 뇌졸중 환 자들은 장애물 보행 시 낙상을 예방하고, 안정적으로 장애물 보행을 위한 운동보상전략에서 정상인과 차이를 보 인 것으로 생각된다. 결론적으로 이 연구는 만성 뇌졸중 환자들의 운동보상 전략을 장애물 보행을 통해서 규명했 다는 점에서 현장에 유용한 시사점을 제공할 것으로 기대된다.

Purpose: Functional recovery of the paretic upper extremity post stroke continues to be one the greatest challenges faced by rehabilitation professionals. Although many tasks require the coordinated participation of both hands, rehabilitation strategies for the most part have focused on the paretic limb. This study investigated whether coupled bilateral coordinated movements and repetitive high frequency TMS enhanced upper limb corticomotor excitability and motor function poststroke. Methods: For this study, we compared the neurophysiological and behavioral changes associated with two such rehabilitation protocols: coupled bilateral training and coupled unilateral training. Twenty chronic stroke patients were randomly assigned to the two training group over 8-week period. For this experiment, transcranial magnetic stumulation, EMG, Ag/AgCI suface electrode, rehabilitation training equipment, jebsen-talyer hand function kit, box & block, and pinch & power grip test kit were used. Results: First, in the box & block and JTT task, coupled bimanual group showed a reduction in movement time in comparision to receiving coupled unilateral group. Second, in the cortical excitability within affected hemisphere, using TMS, an increased in map volume, and map number following coupled bilateral group. Overall, these finding suggest that a coupled bilateral movement and high frequency repetitive TMS protocol effective in recovering upper limb motor function and cortical excitability in chronic stroke patients.

본 연구는 만성 뇌졸중 환자 30명을 대상으로 무작위로 실험군 17명과 대조군 13명으로 나누워서 주 5회 30분씩 12주 동안 실시 하였다. 실험군은 주 4회는 일반적인 작업치료(상지기능증진치료 및 일상생활훈련)를 실시하고, 주 1회 치료정원을 이용한 원예치료 를 실시하였다. 반면에 대조군은 주 5회 일반적인 작업치료만 실시 하여, 치료정원을 이용한 원예작업치료가 삶의 질에 미치는 영향을 알아보고자 하였다. 실험결과 실험군과 대조군 모두 통계적으로 유 의하게 삶의 질 향상이 나타났지만, 실험군이 대조군보다 통계적으 로 높게 나타났다. 본 연구에서의 치료정원을 활용한 원예작업치료 프로그램은 환자가 활동을 이해하고 적절한 수준의 활동을 제시받 기 위해 작업분석 후 동기부여, 적응, 수행기술, 사회적응기술이란 4단계로 등급화(garding)하여 각 단계에 적합한 프로그램으로 구 성하였다. 치료정원에서의 원예활동프로그램을 통해 병원생활에 서 자기만족감이 향상되고, 우울감이 감소되어 삶의 질 향상으로 이어졌다고 사료된다. 이러한 결과를 통해서 만성 뇌졸중 환자에게 치료정원을 이용한 원예작업치료가 삶의 질에 미치는 영향을 주는 것으로 생각하지만, 원예작업치료 프로그램이 구체적으로 뇌졸중 환자의 삶의 질에 어떤 영향 미치고, 구체적 개선부분을 찾기엔 제 한이 있으므로 앞으로 지속적인 연구가 필요하다고 사료된다. 만성 뇌졸중 환자의 치료기간이 늘어나고 지역사회 중심의 재활치료공 간이 확대됨에 따라 장기치료계획의 수립이 필요하며 만성뇌졸중 환자가 지역사회에 생활 할 수 있는 활동 프로그램이 필요한 시기 라고 생각한다. 앞으로도 원예를 활용한 다양한 프로그램이 만성뇌 졸중 재활과정 및 삶의 질에 영향을 미칠 수 있는 연구가 필요하다 고 사료된다.
