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.

This research was conducted to see the correlation between changes of ankle Joint Position Sense and Sway Area through Unstable Surface training. For the study, 48 healthy males and females were randomly divided into an unstable surface group(n=24) and a stable surface group(n=24). Then, they were asked to carry out the same exercise program three times a week for six weeks. The unstable surface group and stable surface group performed the exercise program on the balance exercise pad and on the hard ground, respectively. As a result, the unstable surface group displayed significantly reduced error of ankle joint position sense and sway area(p<.05). Moreover, a significant correlation between variances of ankle joint position sense and sway area was only found in the unstable surface group. In conclusion, this study demonstrated that there was a significant correlation between changes of ankle joint position sense and sway area through proprioceptive sense training on the unstable surface.

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 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.

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.

This study examined the effects of 8-weeks hip muscle training on the hip joint abductor muscle isokinetic strength and foot pressure distribution in elite players with chronic ankle instability (N=19). A total of 19 subjects had chronic ankle instability from at least 2 ankle sprains, and were given 8-weeks hip muscle training exercise. The hip muscle strength of the elite players with chronic ankle instability increased significantly, but the foot pressure distribution and ratio of the foot pressure distribution of the elite players with chronic ankle instability did not reach statistical significance and the ratio of the foot pressure distribution showed a similar trend. These results suggest that the strength and foot pressure distribution of the affected-side might increase to that of the unaffected-side. The 8-weeks hip muscle training helped improve the chronic ankle instability of the elite players. Therefore, the hip muscle strength and foot pressure distribution are the primary factors of a rehabilitation program on ankle sprains.

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.
