이 연구는 중학교 야구선수를 대상으로 8주간의 케틀벨 훈련이 기능적 움직임 및 균형성에 미치는 영향을 분석하고자 하였다. 중학교 야구선수 14명을 케틀벨 집단(n=8), 통제 집단(n=6)으로 무작위 배정한 후 케틀벨 훈련을 주 2회, 60분간 실시하였다. 그리고, 훈련 전과 8주 훈련 후 FMS, Y-밸런스 테스트 및 스마트 슈즈를 이용하여 정적, 동적 균형성을 검사하였다. 케틀벨 훈련 효과를 검증하기 위해 반복이원변량분석을 실시하였고, 시기와 집단 간 상호작용이 있을 경우 집단 별로 대응표본 t-검정을 실시하였다. 연구 결과, FMS 점수는 IL(Inline Lunge)과 FMS 총점(TS)에서 유의한 차이가 나타났으며, FMS의 다른 변인에서는 유의한 차이가 없었다. YBT 점수는 왼쪽 AT를 제외한 모든 YBT변인에서 유의한 차이가 나타났다. 또한 Smart shoes를 이용한 균형성 검사에서는 모든 변인에서 집단과 시기 간 유의한 상호작용 효과는 나타나지 않았다. 결론적으로 중학교 야구선수의 케틀벨 훈련 적용은 기능적 움직임과 기능적 균형성과 관련된 FMS 및 YBT 점수에는 효과가 있었지만, 족압분포로 평가하는 Smart Shoes를 사용한 정적/동적 균형성에는 영향을 미치지 않는 것으로 나타났다. 이 연구의 결과들은 중학교 야구선수의 훈련 프로그램 작성에 필요한 기초자료로 제공될 수 있을 것으로 판단된다.

PURPOSE: This study aimed to determine the effect of active trunk training in the sitting position on balance and energy consumption in early stroke patients. METHODS: The subjects of this study were twenty four early stroke patients were recruited and randomly divided into two groups; experimental group (n=12) and control group (n=12). The subjects in the experimental group participated in active trunk training (20 min) and conventional physical therapy (20 min) five times a week for four weeks. The control group conducted general balance exercise (20 min) and conventional physical therapy (20 min) five times a week for four weeks. The outcomes were assessed using the Berg balance scale, Timed up and go test and energy cost and physiological cost index. RESULTS: Both groups showed a significant increase in their Berg balance scale and significant decrease in their Timed up and go test score, and energy cost and physiological cost index (p<.05). Compared to the control group, the experimental group experienced a greater increase in the Berg balance scale (p<.05) and a larger decrease in the timed up and go test score, and energy cost and physiological cost index (p<.05). CONCLUSION: We suggest that active trunk training in the sitting position may be effective in improving balance and energy consumption in early stroke patients. Thus, active trunk training is important for such patients. Further studies are needed to better understand the effectiveness of trunk training in early stroke patients.

Objective: The aim of this study was to investigate the effect of balance training with plantar flexor stretching on ankle dorsi flexion range of motion (ROM), balance, and gait ability in stroke patients. Design: A randomized controlled pilot trial. Methods: Thirty stroke patients volunteered to participate in this study. The subjects were randomly allocated to two groups: the experimental group (n=15) received the neurodevelopment therapy plus balance training with plantar flexor stretching for 20 minutes in one session. The control group (n=15) received the same neurodevelopment therapy plus plantar flexor static stretching for 20 minutes in one session. Both groups underwent sessions four times a week, for a total of 4 weeks. Measurements included passive range of motion (PROM), active range of motion (AROM) of ankle dorsiflexion using a goniometer, timed up and go (TUG), the functional reaching test (FRT), and the 10 m walk test (10 MWT). Results: There were significant improvements in AROM and PROM of ankle dorsiflexion, TUG, and FRT scores after the intervention in the experimental group (p<0.05). However, the control group showed no statistically significant differences except for PROM of ankle dorsiflexion. The experimental group showed a significant improvement in PROM, TUG, and FRT scores compared to the control group (p<0.05). Conclusions: Balance training with plantar flexor stretching improves ankle dorsiflexion ROM and balance ability in patients with stroke. Therefore, this therapeutic intervention will be effective for rehabilitation of stroke patients in the clinical setting.

Objective: To study the effects of gait training with additional weight and gait training with non-additional weight on balance ability and gait ability in patients with chronic stroke through comparative analysis. Design: Randomized controlled trials. Methods: The subjects were divided randomly into two groups: additional weight group (AWG, n=12), and non-additional weight group (NAWG, n=10). Both groups received general physical therapy for 30 min in 1 session, 5 sessions per week during 6 months. The AWG practiced gait training with additional weight of 0.1 and 0.5 kg for 20 min a day, 3 days per week for 6 months and the NAWG practiced gait training with non-additional weight for 20 min a day, 3 days per week for 6 months. Patients in both groups were instructed to walk as fast as they could along a 35 m long track (straight for 20 m and curved for 15 m). Patients walked with their hemiplegic side on the inside of the track while a physical therapist followed along to instruct patients to maintain a straight posture. Balance ability was tested with the Functional Reach Test, the Timed Up and Go test, and the Berg Balance Scale, and gait ability was tested with GAITRite. The results of balance and gait ability were analyzed before and after interventions. Results: A significant increase in FRT, TUG, BBS was seen in both groups after intervention (p<0.05). A significant increase in gait ability was seen in the AWG after intervention (p<0.05). For balance and gait ability, the results from the AWG was significantly improved compared with the NAWG (p<0.05). Conclusions: Gait training with additional weight improves balance ability and gait ability in stroke patients, this gait training method is effective and suitable for stroke patients to increase the ability of functional performance.

PURPOSE: This study was conducted to determine the effects of whole-body tilt exercise with visual feedback on trunk control, strength, and balance in patients with acute stroke. METHODS: The study included 18 patients with acute stroke who were randomly allocated to a Whole Body Tilt Exercise Group (WBTEG, N=9) and a General Trunk Exercise Group (GTEG, N=9). The WBTEG conducted whole-body tilt exercises with visual feedback, and the GTEG performed general trunk exercises. Both groups performed the exercises five times a week for 4 weeks. Outcomes were assessed using the trunk impairment scale (TIS), the trunk flexor and extensor strength test, the static balance test, and the Brunel Balance Assessment. RESULTS: After 4 weeks of intervention, both groups showed significantly improved TIS scores, muscle strength, and balance components (p<.05 in both groups). However, the improvement in TIS, muscle strength, and static balance in the WBTEG was significantly better than that in the GTEG (p<.05). CONCLUSION: Although both groups in this study showed post-intervention improvement, patients from the WBTEG who received visual feedback demonstrated more improvement. These findings indicate that whole-body tilt exercise with visual feedback may be effective at improving trunk control, trunk muscle strength, and balance in patients with acute stroke. Further studies are needed to gain a better understanding of the effectiveness of whole-body tilt exercise in patients with acute stroke.

Objective: The aim of this study is to investigate the effects of whole body vibratory stimulation on muscle strength, balance, and fall efficacy among super-aged women. Design: Randomized controlled trial. Methods: Twenty-eight super-aged women over 80 years of age were assigned to either the experimental group (n=14) and control group (n=14). The experimental group received an exercise program that used the whole body vibratory stimulation with a frequency of 30 Hz and amplitude of 3 mm, and the control group received an exercise program without vibratory stimulation. Intervention was provided for 4 weeks, 3 sessions per week, and 30 minutes per session. In order to measure lower extremity muscle strength the 30-second chair stand test (CST) was used. The Berg Balance Scale (BBS) was used to measure dynamic balance. Static balance was measured by tracking the path length, velocity, and area of the center of pressure (CoP). The Falls Efficacy Scale (FES) was used to measure the subjects' fear of falling. Results: Both the experimental and control group demonstrated statistically significant increase in muscle strength, dynamic balance, and fall efficacy (p<0.05). Only the experimental group showed significant improvements in static balance before and after the intervention (p<0.05). The experimental group showed significantly greater improvements in CST, BBS, and CoP (path length, velocity) than control group (p<0.05). Conclusions: Whole body vibratory stimulation exercise is shown to be a safe and appropriate physical therapy intervention method to enhance muscle strength, balance, and fall efficacy of super-aged women.
