Purpose : This meta-analysis was aimed at guiding future research in stroke treatment and to provide real-world data relating to the effects of aquatic exercise therapy on balance in patients with chronic stroke. Methods : We performed a meta-analysis comprising 22 studies involving aquatic exercise therapy performed between 2006 and 2017. A meta-analysis software program was used to calculate the mean effect size, effect size by intervention, and effect size by outcome. We also performed a meta-regression analysis and an analysis of publishing bias. Results : The mean effect size was 0.563. The effect size by outcome was observed to be the largest for the functional reach test, followed by the Berg balance scale, balance equipment, the Timed Up and Go test and one leg standing. Meta-regression analysis showed that effect size increased with an increase in the duration, number, length of exercise session. Conclusion : Aquatic exercise therapy appears to show a moderate effect on balance in patients with chronic stroke. A meta-analysis is warranted for further research to determine the effects of aquatic exercise on walking, muscle strength, and range of motion.

Background: As technology has progressed, various robot-assisted devices have been developed to reduce therapists' labor and assist in therapy. However, due to their many limitations, it is more practical to use traditional mechanical devices. The grahamizer is one such traditional mechanical device used clinically to rehabilitate the upper extremities. No study has yet established the efficacy of the grahamizer in individuals with stroke. Objects: This study investigated the immediate change in arm reaching after the use of a grahamizer. Methods: Twenty-two stroke survivors participated in this study (11 males and 11 females). The reaching of the more-affected arm was measured three times using the three-dimentional electromagnetic motion tracking system "trakSTAR". After the first measurement, the subjects performed 500 rotatory arm exercises using the grahamizer. To assess the grahamizer's effect, the subjects were remeasured in the same way. Results: There were significant increases in the reaching distance (p < 0.05) and movement smoothness (p < 0.05) of the more-affected arm after using the grahamizer. Conclusion: Our study confirms that using the grahamizer is beneficial in the rehabilitation for improving movement of the more-affected arm in stroke survivors.

Purpose: The aim of this study was to evaluate the effect of Bridge exercise with abdominal drawing-in on static and dynamic balance in patients with stroke. Methods: Forty patients with stroke participated in this study. Participation was randomly assigned to the Bridge exercise group (n=20) and the Bridge exercise with abdominal drawing-in group (n=20). A bio-feedback device was used when patients performed the Bridge exercise with abdominal drawing-in. This training was performed without any motion on the patient's spine and upper belly part, and the pressure was held with the biofeedback device as 40-70 mmHg. Both groups received training 30 minutes per day, three times per week, for four weeks. Weight bearing, anterior limit of stability, and posterior limit of stability for static balance ability were measured, and Berg balance scale (BBS), Timed up and go test (TUG) for dynamic balance ability were also measured. Results: Participants showed significant differences between pre- and post-mediation in terms of weight bearing, anterior limit of stability, posterior limit of stability, Berg balance scale, and Timed up and go test (p<0.05). The Bridge exercise with abdominal drawing-in group showed a more significant increase (p<0.05). Conclusion: According to the results of this study, both exercises were effective for improving the static and dynamic balance ability. However we suggest that the Bridge exercise with abdominal drawing-in is more efficient for increasing balance ability in patients with stroke.

본 연구는 패턴화된 감각 증진(Patterned Sensory Enhancement, PSE) 기법이 뇌졸중 환자의 상지 기능에 미치는 즉각적인 효과를 알아보기 위해 PSE와 단순 리듬 자극 간의 차이를 비교분석 하였다. 연구 대상은 서울시와 수원시 소재의 재활병원에서 입원 치료 중인 뇌졸중 편마비 환자 16명이며 실험군과 대조군으로 각각 8명씩 배치하였다. 본 연구의 종속변인은 뇌졸중 환자의 환측 상지 기능으로 6가지 동작의 관절가동범위(ROM, range of motion)와 장악력이며 실험군에게는 PSE를, 대조군에게는 메트로놈으로 제공되는 단순 리듬 자극을 제공하였다. 실험은 음악 자극이 없을 때와 있을 때의 같은 상지 기능을 측정하는 순서로 진행되었으며 측정한 값의 경향을 정확하게 파악하기 위해 동일한 실험을 총 2회 실시하여 평균값을 도출하였다. 연구 진행 결과, PSE를 제공받은 실험군은 음악을 들으며 동작을 수행할 때 상지 관절가동범위가 유의미하게 향상되는 즉각적인 효과를 보였으나(p < .05), 대조군은 즉각적인 효과를 보이지 않았다. 이는 단순 리듬 자극보다 PSE가 상지 운동 향상에 더 적절하게 적용될 수 있다는 것과 음악의 청각적 패턴이 운동 범위의 확장 즉, 운동 향상에 영향을 줄 수 있다는 것을 보여주었다. 본 연구는 PSE가 상지 운동 기능에 미치는 즉각적인 영향을 단순 리듬 자극과 비교분석하였다는 점에서 의의가 있으며 음악 요소의 특징이 유도하고자 하는 신체 운동의 목표와 밀접한 연관성을 가질 때 효과적으로 영향을 미칠 수 있음을 시사한다.

Modem concepts of gait rehabilitation after stroke favor a task-specific repetitive approach. In practice, the required physical effort of the therapists limits the realization of this approach. Therefore, a mechanized gait trainer enabling nonambulatory patients to have the repetitive practice of a gait-like movement without overstraining therapists was constructed. In this study, we developed an active gait training system for patients with gait disorder. This system provides joint movements to patients who cannot carry out an independent gait. It provides a normal stance-swing ratio of 60:40 using an eccentric configuration of two gears. Joint motions of the knee and the ankle were evaluated with using the 3D motion analysis system and compared with the results from the multi-body dynamics simulation. In addition, clinical investigations were also performed for low stroke patients during the 6-week gait training. Results from the dynamics simulation showed that joint movements of the knee and the ankle were affected by the gear size, the step length and the length of the foot plate, except the radius of curvature of the foot guide plate. Also, the 6-week gait training revealed relevant improvements of the gait ability in all low subjects. Functional ambulation category levels of subjects after training were 2 in three patients and 1 in a patient. The developed active gait trainer seems feasible as an adjunctive tool in gait rehabilitation after stroke.
