Objective: The purpose of the study was to investigate the effect of shoe sole deformation on the muscle activity and balance of the lower extremities when standing on one foot. Design: Crossed-control group study Methods: A total of 18 healthy adults participated in this study. 9 participants with normal shoe and 9 participants with deformed in shoe out-soles (wear shoes) were included. Muscle activity of the tibialis anterior, fibularis longus and gluteus medius during one leg standing was measured using a electromyography. A balance board was used to evaluate balance ability when standing on one leg. The balance ability when standing on one leg was measured by the sway speed and distance of the center of gravity. Results: Muscle activity of the tibialis anterior, fibularis longus and gluteus medius was no significant difference between groups (P > 0.05). Balance ability when standing on one leg was significantly different from the group wearing normal shoes in all variables related to the sway distance and sway speed of the center of gravity. Conclusions: Through this study, the wear of the outer sole of the shoe indirectly confirmed the effect on the wearer's lower extremity muscle activity and balance ability when standing on one foot. These results of this study are expected to be used as basic data for future studies on shoe wear, lower extremity muscle activity and balance ability.

Background: Task-oriented training on an unstable support surface is an effective intervention for improving the ankle joint stability and muscle strength in patients with ankle instability. This study examined the effects of balance training on an unstable support surface in patients with ankle sprains with ankle instability. Methods: Forty-four patients with ankle sprains participated in this study. Screening tests were performed and assigned to an experimental group, who performed task-oriented training on an unstable support surface (n=22), and a control group, who performed task-oriented training on a support surface (n=22) using a randomization program. All interventions were applied 3 times per week for 4 weeks. The numeric rating scale (NRS), cumberland ankle instability tool (CAIT), balance ability, muscle activity, and muscle thickness were compared to evaluate the effects of the intervention. Results: Both groups showed significant differences in the NRS, CAIT, balance ability, and muscle activity between before and after the intervention (p<.05). In addition, there were significant differences in balance ability, muscle activity, and muscle thickness between the experimental and control groups (p<.05). Conclusion: Task-oriented training on an unstable support surface is an effective intervention for improving the balance ability, muscle activity, and muscle thickness during contraction.

PURPOSE: This study examined whether ankle joint stabilizing taping and muscle control taping influenced the ankle range of motion (ROM), muscle tone, and balance ability in chronic stroke patients. METHODS: Ten stroke patients were assigned randomly to experimental group 1 (joint stabilization taping n = 5) and experimental group 2 (Muscle control taping n = 5). After general physical therapy in both groups, ankle stabilization taping was applied to experimental group 1, and muscle control taping was applied to experimental group 2 three times a week for a total of six weeks (18 times). RESULTS: The muscle tone and stiffness of the gastrocnemius (GCM) showed significant differences between the experimental 1 and experimental 2 groups (p < .05). The Berg Balance Scale (BBS) and ROM also showed significant differences within the experimental 1 and experimental 2 groups (p < .05). The BBS and ROM also showed no significant differences between the experimental 1 and experimental 2 groups (p > .05). CONCLUSION: This study examined the muscle tone, balance, and ROM on the paraplegic side of stroke patients using kinesio taping, and the effect of the taping application method was confirmed from the preceding study. Therefore, it can decrease the paralysis side muscle tone and improve the ROM and balance ability.

Objective: The purpose of this study was to investigate the effects of combining Mulligan taping and flossing bands on lower limb muscle activity and static and dynamic balance. Design: A randomized controlled trial. Methods: Sixty-eight patients with chronic ankle instability were randomized into three groups that were treated with Mulligan taping (MT, n=22), flossing band (FB, n=23) and Mulligan taping combined with flossing band (MT+FB, n=23), and various parameters were compared before and after the intervention. The muscle activity of the lower extremities, including the tibialis anterior, peroneus longus and medial of gastrocnemius muscles was measured using BTS FREE EMG 1000, while the static and dynamic balance were measured using the Biorscuue balance measuring equipment. Results: There was a significant difference in muscle activity of the tibialis anterior muscle, before and after the intervention, in the MT group (p<0.01), FB (p<0.001) and MT+FB (p<0.001). There was also a significant difference in the muscle activity of the tibialis anterior muscle in the MT+FB group when compared with that in MT and FB groups (p<0.05). We also observed a significant difference in the dynamic balance all the groups (p<0.001). Conclusions: Therefore, combining Mulligan taping and flossing bands for patients with chronic ankle instability may improve dynamic balance and tibialis anterior muscle activity.

The purpose of this study was to investigate the effects of core muscle training on balance ability. Forty subjects in their 20s participated in a 6 week core muscle training program. Balance ability before and after the intervention were assessed and analyzed using the Romberg test, which was conducted on the floor, pedalo, and balancefit. The differences between the measurement methods of balance ability using varied platforms was also compared and analyzed. After the 6-week core exercise training program, the training group represented statistically significant increases in all 3 methods for static balance ability. In the control group, all 3 methods represented no statistically significant increases. Upon comparing the different methods of the Romberg test, there were no notable differences between conducting the test on varying platforms for both groups. This study suggests that the core muscle exercise training program increased the balance ability.

Falling is one of the major public problems to the elderly, resulting in limitations of daily living activities. It can be induced by the functional loss of the balance ability and muscle strength in the elderly. It has been, however, not well investigated to suggest an effective methodology improving the balance ability and muscle strength for the prevention of the falling due to lack of information about the characteristics of the balance and muscle activations responded to the dynamic motions. The aim of the current study is, therefore, to identify the characteristics of the balance and muscle activations responded to the dynamic motions in Anterior-Posterior(AP) and Medial Lateral(ML) directions. For that, a motion capture system with eight infrared cameras, surface electromyogram system and Wii Fit system with a customized variable unstable base were used and kinematic and kinetic data obtained from the systems were analyzed for five healthy male($24.8{\pm}3.3years$, $177.4{\pm}2.0cm$, $73.9{\pm}12.9kg$, $23.5{\pm}4.0kg/m$). The results showed that the characteristics of the balance and muscle activations were differently responded to between the dynamic motions in Anterior-Posterior(AP) and Medial Lateral(ML) directions. These findings may indicate that customized dynamic motions should be applied to the training of the balance ability and muscle strength for the effective prevention of the falling. This study may be meaningful to providing basic information to establish a guideline improving effectively the balance ability and muscle strength.

Purpose : The purpose of this study was to compare the effects of ankle balance training on unstable and stable surfaces to discover on which surface the proprioception, balance and muscle strength of obese middle aged women improves more. Method : Thirty obese middle-aged women were randomly recruited and divided into two groups (training on an unstable surface, training on a stable surface). The subjects in each group participated in the training for six weeks, three times per week for 30 minutes each session. Proprioception was measured using Dualer IQ digital inclinometer; sway length (SL) and sway area (SA) of center of pressure, and limit of stability (LOS) were measured for balance; muscle strength before and after the training was measured using manual muscle testing. Results : There were significant improvements in the subscales of the proprioception, balance and muscle strength in those who participated in ankle balance training on the unstable surface, and in those who participated on the stable surface. However, before and after the intervention, there were no differences between those who had the balance traning on the unstable surface and those who had the balance traning on the stable surface. Conclusion : Unstable and stable surface ankle balance training are both effective in improving the proprioception, balance and muscle strength of obese middle-aged woman.

PURPOSE: This study examined the comparative effects of an ankle sensorimotor training program combined with hip strengthening exercise (ASTPCHSE) and ankle sensorimotor training program (ASTP) alone on muscle strength, static balance, and dynamic balance in individuals with functional ankle instability. METHODS: Sixteen research participants with functional ankle instability were enrolled in this study. The participants were divided randomly into the ankle sensory motor training program group and the ankle sensory motor training program combined with the hip strengthening exercise group. Each group performed a series of exercise programs two times per week for four weeks. The Cumberland ankle instability tool (CAIT) was used to measure the participants' functional ankle instability. A Balance trainer 4 was applied to assess the static and dynamic balance, and a Primus RS multimodal dynamometer was used to evaluate the muscle strength. RESULTS: No significant differences in static balance, dynamic balance, and muscle strength were found between the ASTP and ASTPCHSE groups (p > .05). On the other hand, the dynamic balance and muscle strength improved in the ASTP and ASTPCHSE groups after the intervention (p < .05). The static balance was not enhanced in both groups after the intervention (p > .05). CONCLUSION: Ankle exercise and an ankle sensorimotor training program combined with hip strengthening exercise are effective in improving muscle strength and dynamic balance in individuals with ankle instability. On the other hand, there are no meaningful differences between ankle exercise and ankle and hip combined exercise.

Purpose: This study aimed to investigate the effect of active vibration exercise on trunk muscle activity, balance, and activities of daily living in patients with chronic stroke. Methods: Twenty-four patients with chronic stroke were randomly assigned to an experimental (n=12) or a control (n=12) group. The experimental group performed an active vibration exercise workout for 20 minutes a day five times a week for 4 weeks using a flexi-bar. Trunk muscle activity was measured using surface electromyography. Balance was measured using the Berg balance scale. Activities of daily living were measured using the functional independence measure. Results: The intragroup comparison showed significant differences in the rectus abdominis, internal oblique, and external oblique muscle activity values, Berg balance scale score, and functional independence measurement values in the experimental group. The intergroup comparison showed that differences in the rectus abdominis and internal oblique external oblique muscle values, Berg balance scale score, and functional independence measurement value for the experimental group were significantly related to those in the control group. Conclusion: Based on these results, this study proved that the active vibration exercise effectively improved trunk muscle activity, balance, and activities of daily living in patients with chronic stroke.
