PURPOSE: This study examined the effects of bilateral ankle dorsiflexors-strengthening exercise on the paralytic tibialis anterior activity, balance ability, and gait function of patients with chronic stroke. METHODS: Nineteen patients with chronic stroke were assigned randomly to the experimental and control groups. All participants received general physical therapy for 60-minutes per session, five times a week, for 6 weeks. In addition, the experimental group (n = 9) performed bilateral ankle dorsiflexion muscle-strengthening training three times a week, 30 minutes per session, for six weeks. The control group (n=10) performed the paraplegic ankle dorsiflexion muscle- strengthening training in the same manner. Before and after the intervention, the paralytic tibialis anterior muscle activity, timed up and go test (TUG), and 10m walking test (10 MWT) were performed. RESULTS: Both groups showed significant improvement in the post-intervention muscle activity of the paralytic tibialis anterior, TUG, and 10MWT compared to that before the intervention (p<.05), but the differences between the two groups were not significant (p >.05). CONCLUSION: Bilateral ankle dorsiflexors strengthening exercise is an effective cross-training method to improve the muscle activity of the paraplegic tibialis anterior, balance ability, and walking function in chronic stroke patients.

Background: Ankle sprain is one of the most common musculoskeletal injuries in the sports population or during usual daily life activities. The sprain can cause functional ankle instability (FAI), and it is very important to treat FAI. However, the optimum intervention method for FAI has yet to be determined. Objects: This study investigated the impact that virtual reality (VR) training program on balance with ankle kinesio taping for FAI. Methods: Twenty-two people were selected for the study and randomly divided into the experimental (n = 11) and the control group (n = 11). The experimental group had attached kinesio taping on the ankle and then implemented a virtual reality exercise program for 30 minutes a day. Nintendo Wii Fit Plus was used for the VR intervention three times a week for four weeks. The control group performed only two measurements without intervention. Results: There were no statistically significant differences in overall, anterior-posterior (AP), medial-lateral (ML) index of the static balance, and significant differences in overall, AP, ML index of the dynamic balance when taping and VR exercise were applied at the same time (p < 0.05). There were no significant differences in overall and ML index of static and dynamic balance compared with before and after assessment between the experimental and the control group, and found differences in AP index of static and dynamic balance (p < 0.05). Conclusion: Kinesio taping may not influence the balance of FAI as great as people expected. VR approach does not affect the static balance of FAI, but it influences dynamic balance in overall, AP, ML index. The authors suggest that VR-based exercises can be used as an additional concept in clinicians for FAI or as part of a home program because the exercises still have limitations.

Background: The purpose of this study was conducted to investigate the effects of the ankle mobilization with movement (MWM) technique on ankle dorsiflexion range of motion (ROM), balance, and gait in patients who underwent total knee replacement (TKR). Methods: Thirty patients with knee osteoarthritis were recruited and randomly divided into two groups: the experimental group (EG; n=15) and the control group (CG; n=15). For five days a week for 3 weeks, participants in the EG were treated with the ankle MWM technique and traditional total knee replacement (TKR) exercise, and those in the CG only performed traditional TKR exercises. The dorsiflexion ROM, balance, and gait of the patients were before and after exercise. Results: Balance system SD was used compare changes in dynamic balance. Patients in the EG group showed statistically significant differences after the intervention (p<.05). In addition, there was a statistically significant difference in dynamic balance between the EG and CG groups after the intervention (p<.05). STT-IBS was used to compare changes in velocity, step length, stride length, and ankle dorsiflexion ROM. Patients in the EG group showed statistically significant differences after the intervention (p<.05). In addition, there was a statistically significant difference in the velocity, step length, stride length, and ankle dorsiflexion ROM between the EC and CG groups after the intervention (p<.05). Conclusion: Our results showed that applying the ankle MWM technique with traditional TKR exercises improved ankle dorsiflexion ROM, dynamic balance, and gait in patients.

Purpose: The aim of this study was to examine the effects of sling exercise on fall risk score, ankle dorsiflexion and balance in community-dwelling elderly women. Method: A 6-week prospective study was conducted to examine the effects of sling exercise. Participants were required to attend their assigned exercise classes three times a week for 6 weeks. Result: After the 6 week study period, PPA fall-risk scores were reduced by 0.90 for the exercise group, which was a significant change (p<.001). Dorsiflexion strength increased significantly (p<.01) by 1.56 kg after the sling exercise. There was a 2.0 cm-increase (p<.05) in FRT and 0.38 second-improvement (p<.01) in TUGT. A 7.88 second-increase in One-leg standing with Eyes Open and a 3.12 second-increase in One-leg standing with Eyes Closed were reported during the 6-week intervention period. Conclusion: The 6-week sling exercise reduced falls risk score significantly (p<=.001) in community-dwelling elderly women by improving fall risk related factors such as reaction time, balance and strength.

Purpose: The isolated exercise therapy and its effect for the treatment of posterior tibial tendon dysfunction (PTTD) is not well known. The purpose of this study was to identify the clinical effect of stretching and strengthening exercise program on the patients' muscle function and range of motion, pain and gait in the management of the early stage PTTD. Materials and Methods: From October 2006 to March 2007, 14 patients with early stage PTTD (stage I or IIa) without surgical intervention were randomly assigned into two groups and we analyzed their clinical results. All patients were female and one who have sprained the same ankle during the program and one who withdrew from the program due to her private reason were excluded. At the last, the exercise group (EG) was seven and the control group (CG) was five. Mann-Whitney U test was used for the comparison of pain, ROM, muscle power, AOFAS score and 5 minute walking test of both groups. Wilcoxon-signed rank test was used for the comparison between the pre and post exercise program in EG. Results: The pain was significantly reduced in EG compare to CG and only the dorsiflexion was significantly increased in EG in the analysis of ROM. The dorsi flexion and plantar flexion power were significantly increased in EG. Conclusion: Our 6 weeks stretching and strengthening exercise program showed noticeably improved clinical result, and therefore it is recommended as one of the useful treatment option in the management of early stage PTTD.

발목 염좌가 발생 시 초기에 응급처지와 고정치료를 하는 것이 매우 중요하며, 재활 및 회복 과정에서 발목을 지지해주는 역할과 냉찜질과 온찜질을 제어해주는 보호대를 사용하는 것이 효과적이다. 이에 인체공학적으로 환자 발목에 맞는 보호대를 제작하여 발목을 제대로 압박해주어 재부상을 방지해줄 것이며, 보호대 자체에서 운동제어를 해줄 수 있게 설계하여 환자의 발목 온도에 따라 자동으로 온도 조절을 통하여 회복을 도모하며, AT분야와 접목시켜 압박센서와 온도센서를 이용하여 환자들이 손상 이전 상태로 회복할 수 있는 인체공학적 발목보호 시스템을 설계하려 한다.

Purpose: The purpose of this study was to investigate the short term effects of ASEJ (ankle strengthening with emphasis on jumping) for 3weeks on strength, mechanical properties, and balance and to compare the balance with and without HH(high-heel) condition. Methods: ASEJ (a combined exercise of squat, heel raise up, and jumping) were performed for the subjects in 11 female ankle instability young females ($21.7{\pm}2.0yrs$ Cumberland ankle instability score $19{\pm}6.5$). To investigate the effect of ASEJ, investigator used dynamometer for measuring strength, MyotonPRO for measuring mechanical properties(tone, stiffness, and elasticity of the muscles), I-Balance test for static balance, and Y-balance test for dynamic balance between the condition with and without HH condition. All data were normally distributed and analyzed using the SPSS 22.0 statistical program. Comparing pre- and post-intervention and the condition with and without HH conditions data were examined using the paired t-test. The level of significance was chosen as 0.05 for all the analyses. Results: 3wks of ASEJ would strengthen leg muscles and increasing muscle tone and stiffness in most muscles however there was decreasing muscle elasticity of gastrocnemious. In addition, the ASEJ improves the static balance for ankle instability young females and increases the dynamic balance when wearing the heels especially. Conclusions: the ASEJ could recommend to improve the strength and balance for ankle instability young females. Also, measuring the balance with HH conditions well represents the risk of ankle damage in female.

본 연구는 만성 발목 불안정성을 가진 엘리트 선수들을 대상으로 8주간의 엉덩이 강화 운동이 엉덩이의 근력 및 족압 분포도의 변화에 어떠한 영향을 미치는 지를 분석하기 위해 실시되었다. 발목에 최소 2회 이상의 발목 염좌를 진단받은 만성 발목 불안정성의 대상자 19명을 대상으로 8주간의 엉덩이 강화 운동을 실시하였으며, 결과에서 엉덩이 강화 운동으로 엉덩이의 외전근력은 유의한 증가를 보였지만 족압의 분포도와 증가비율은 유의한 변화를 보이지 않았다. 이 결과는 운동 후, 환측과 건측의 근력과 족압분포의 차이가 나타나지 않아 환측의 근력과 족압분포가 건측의 수준만큼 증가된 것으로 생각되며 이는 8주간의 엉덩이 강화 운동이 발목의 불안정의 개선에 일정정도 효과가 있는 것으로 사료된다. 이러한 결과를 토대로 만성 발목 불안정성을 가진 대상자들의 회복과 재발방지를 위한 재활운동 프로그램의 구성요인으로서 엉덩이 외전근력 강화와 족압 분포도에 대한 부분을 중요하게 반영하는 것이 효과적일 것으로 사료된다.

PURPOSE: This study examined the changes in the cross-sectional area (CSA) of the abductor hallucis muscle during various ankle positions while performing toespread-out (TSO) exercise. METHODS: Thirty subjects with an average age of 22.1 years were recruited for this study. All subjects were firstly measured for the angle of their first metatarsophalangeal joint using a goniometer. Those with angles greater than 15° were allocated to the HV group. The remaining subjects were placed in the normal group. The CSA of the abductor hallucis was measured by ultrasound in the resting position with no movement and three ankle positions: neutral (0°), plantarflexion (30°), and dorsiflexion (30°). All data were analyzed using a two-way mixed analysis of variance between the groups (normal and HV group) and within the groups (resting, neutral, plantarflexion, and dorsiflexion) to determine the group x position interaction effects. RESULTS: During TSO exercise in the normal group, the CSA of the abductor hallucis was significantly greater in both the plantarflexion and neutral positions compared to the resting position (p_adj < .01), and plantarflexion was significantly greater than the dorsiflexion position (p_adj < .01). During the TSO exercise in the HV group, the CSA of the abductor hallucis for plantarflexion was significantly greater than it was for the resting, neutral, and dorsiflexion positions (p_adj < .01). CONCLUSION: Based on the above results, the TSO exercise in plantarflexion is an effective rehabilitation exercise for subjects with HV.
