Purpose: The purpose of this study is to compare the effects of board training and complex training on ankle stability in taekwondo college students with a history of ankle sprain. Methods: Twenty-seven taekwondo college students were randomly assigned into a board training (BTG, n=9), complex training (CTG, n=9), or control groups (CG, n=9). BTG carried out disk and trampoline training 3 times a week for 8 weeks. CTG carried out resistive and plyometric training 3 times a week for 8 weeks. All subjects completed ankle stability test for static and dynamic balance in anterior/posterior and medial/lateral stability with New Balance System (BIODEX Medical System, USA). Results: There were no significant differences between three groups in ankle stability. Those who participated in BTG significantly improved static balance of left foot in anterior/posterior stability, and dynamic balance of both feet in mediolateral stability, but there were no change in CTG. Conclusion: Board training is more improved ankle stability in taekwondo college students with a history of ankle sprain than complex training.

Objective : The purpose of this study is to evaluate the effects of hip joint exercises and orthotics on RCSP, ankle's range of motion, and core muscle strength of middle school students with pes planus. Method : Out of the original pool of 200 students, 60 students with pes planus (RCSP < -2) were selected for the study. The selected 60 students were then divided into four groups. The first group was a combined orthotics and exercise group (12 students), the second was the orthotics-only group (9 students), the third was the exercise-only group (8 students), and the last was the control group (10 students). Exercise groups worked out twice a week for 60 minutes per session over 8 weeks. The independent variables were corrective hip joint exercises and orthotics. The dependant variables consisted of kinematic and kinetic variables. The kinematic variables were RCSP, and ankle's range of motion (dorsiflexion and plantarflexion). The kinetic variables were muscles forces that consist in core muscle strength, which are hip joint adduction, abduction, and flexion muscles forces. Statistical analysis was performed via SPSS 18.0 with multivariate analysis of covariance (MANCOVA) and a paired t-test was used. Results : The left foot was more responsive to the treatments, both exercise and orthotics, than the right foot. RCSP improved significantly in the left foot for the first and third groups. Only the first group significantly improved hip joint adduction, abduction, and flexion muscles' strengths. As for the ankle's range of motion of the left foot, plantarflexion showed improvement when treated with exercise, orthotics, or both. Conclusion : This study found that exercise is more effective in correcting RCSP and foot orthotics is more effective in reinforcing core muscle strength. Future studies should expand on these results to examine the relationship between the ankle, hip, and pelvis.

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.

Purpose: The purpose of this study was to investigate the effects of a four week unilateral isokinetic exercise program applied to ankle on the one-leg stance balance performance of ipsilateral and contralateral lower-limbs. Methods: Subjects were randomly assigned to either a right ankle training program (n=12) or a control group (n=12). The training group received unilateral ankle isokinetic exercise of the dominant side for 4 weeks, whereas control group did not. Ipsilateral and contralateral one-leg balance were measured before and after intervention using the Biodex Balance System. Results: Improvements of stability scores, such as APSI, MLSI, and OSI, from pre-test to post-test were significantly different greater for the training group when the control. Conclusion: The results of this study suggest unilateral ankle strengthening exercise transfers benefit to the untrained limb by a cross-education effect, and that this type of exercise should be considered to improve one-leg standing balance of trained and untrained lower-limbs.

For professional drivers, there is a possibility to have musculoskeletal disorders on ankle joint due to repetitive pedaling operation. Therefore, this study have focused to examine ankle active range of motion (AROM), dorsiflexor strength, and pressure pain threshold (PPT) of tibialis anterior muscle (TA) in taxi drivers compared to a age-matched control group. Thirty male taxi drivers with at least 10 years of driving experience and thirty male sedentary workers were evaluated for ankle AROM, dorsiflexor strength, and PPT of TA. Multiple independent t-tests were used to identify significant differences between two groups. For the results, taxi drivers had significantly less AROM in dorsiflexion and greater AROM in external tibial rotation compared to the control group. Also, dorsiflexor strength and PPT of TA in taxi drivers was significantly lower than in the control group. This study indicates that the repetitive ankle movements associated with driving have an effect on ankle AROM, dorsiflexor strength, and PPT of TA and may lead to work-related musculoskeletal disorders on ankle. Professional drivers may need to be educated to prevent a potential musculoskeletal disorders associated with repetitive movement.

Background & Purpose : The purpose of this study is to evaluate the impairment of SVMC(selective voluntary motor control) of the lower extremity by assessing each joints of lower limb and to analyze the motional relationship between each joints of lower limb using SCALE(Selective Control Assessment of the Lower Extremity) during the swing phase of gait cycle in children with spastic diplegia. Method : 11 children with spastic diplegia CP who could walk independently and 10 normal developing children were participated. SCALE(Selective Control Assessment of the Lower Extremity) assessments were conducted for 11 children with CP. Gait analysis were accomplished in all participants. Qualisys motion analysis was used as a statistical tool to assess the motional relationship between hip joint, knee joint and ankle joint in each limb. We used descriptive statistics, cross-tabulation, independent t-test, linear regression to analysis motional relationship between each joints of lower limb using by SPSS ver.17.0. Result : Firstly, there were significant differences in SCALE scores between the cerebal palsy group and the control group in knee joint(p<0.05), but no significant difference in hip and ankle joints during the swing phase of gait cycle. Secondly, the difference of SCALE scores showed no statistical motional difference in knee and ankle joints during the swing phase, and showed significant motional difference in hip joints during the swing phase(p<0.05). Thirdly, there was a liner relationship between the motion of hip and ankle joints during the swing phase. Conclusion : The nature of SVMC(selective voluntary motor control) in each joints of the lower limb may reflect the ability of gait, thus SCALE may be used for assessing and for treating the cerebal palsy patients who are able to walk independently. Also we knew that the impairment of SVMC(selective voluntary motor control) increases from the proximal to the distal joints.

Background: During postural control, older adults are more dependent on proprioception than are young adults. Ankle proprioception, which plays an important role in maintaining postural balance, decreases with age. Published studies are insufficient to establish a significant age difference in postural sway resulting from the known age-related decrease in ankle proprioception and do not examine various detailed test conditions. Objects: The present study aimed to compare ankle proprioception between older and younger groups along dimensions of position vs. force proprioception and dorsiflexion vs. plantarflexion. The present study also aimed to compare postural sway between young and older women during quiet standing under two sensory conditions. Methods: We recruited seven young women aged 21-24 and seven older women aged 60-63. Ankle proprioception was assessed as the accuracy of the joint position sense (JPS) and the force sense (FS). Postural sway was assessed using center-of-pressure measurements recorded during quiet standing under two sensory positions: eyes open and eyes closed with head tilted back. Results: Older women had lower JPS in dorsiflexion and lower FS in plantarflexion than did younger women. We found no significant age differences in JPS in plantarflexion or in FS in dorsiflexion. We observed a main effect of group on postural sway in two sway parameters out of three. We observed significant differences in JPS with dorsiflexion, and in FS with plantarflexion. Conclusion: Proprioception for ankle plantar flexor decreased more significantly with aging than did that for ankle dorsiflexor, accounting for the impaired postural balance observed in older women.
