Purpose : We investigated the effect of anti-flexion taping at the proximal interphalangeal joints on the gait in stroke patients with clawing toe. Methods : Nineteen patients (mean age $63.26{\pm}9.16$ years) with clawing toe were studied. Gait performance was measured under two different conditions : (1) non-tape (2) application of tape. Gait velocity, step time and stride length were examined with the GAITRite system Results : Compared to the non-tape control condition, step time of the hemiparetic side increased significantly after the application of tape(p=0.03). There was no significant mean differences between the taped and control conditions for stride length of the hemiparetic side and velocity. Conclusion : Whilst the anti-flexion tape at the proximal interphalangeal joints changed the walking by providing significant step time effect, positive changes were noted in stride length of the hemiparetic side after tape application. These findings indicate that anti-flexion tape procedures do not significantly alter stride length of the hemiparetic side and velocity.

Background: The gastrocnemius (GCM) is one of the lower extremity muscles that tend to tighten easily. GCM tightness results in limited ankle dorsi-flexion (DF), especially when the knee joint is fully extended. Joint flexibility is determined by the morphological and physiological characteristics of joints, muscles, tendons, and ligaments. Impaired joint flexibility can be attributed to increased susceptibility to muscle injury. High-frequency diathermy is clinically used to reduce pain and muscle tightness and to improve limited range of motion. Objects: This study aimed to investigate the immediate effects of high-frequency therapy in subjects with GCM tightness. Methods: The study was designed as a one-group before-after trial. The subjects included 28 volunteers with GCM tightness (an active ankle DF angle of less than 12°) without any known neurological and musculoskeletal pathologies in the ankle and calf areas. WINBACK Transfer Electrode Capacitive and Resistive Therapy equipment was used to apply high-frequency therapy to the subjects' GCMs for 10-15 minutes. The pennation angle and the fascicle length of the GCM were measured using ultrasonography. The flexibility of the ankle joint, peak torque to the passive ankle DF (Biodex), and soft tissue stiffness (MyotonPRO) were also measured. Results: The pennation angle was significantly decreased following the treatment; however, no significant difference in the fascicle length was found (p < 0.05). The flexibility was significantly increased and both the passive peak torque to passive ankle DF and the soft tissue stiffness significantly decreased (p < 0.05). Conclusion: High-frequency therapy is immediately effective for improving the muscle's architectural properties and functional factors in subjects with GCM tightness. Further longitudinal clinical studies are required to investigate the long-term effects of high-frequency therapy on subjects with GCM tightness from various causes.

Purpose: The purpose of this study is to investigate the effect of visual and auditory stimulation randomly applied to healthy adults on walking. Design: Randomized Controlled Trial. Methods: Twenty-six healthy students in S college were randomly divided into visual feedback group (n=13) and auditory feedback group (n=13). The visual feedback group walked using four conditions. 1) In the red screen was shown, clap twice to the right, 2) In yellow screen, clap twice to the left, 3) In green screen, clap twice over head. 4) Do not clap in purple screen. The auditory feedback group walked using four conditions. 1)in red, clap twice to the right, 2) In yellow, clap twice left, 3) In green, clap twice over your head. 4) Do not clap in purple. All subjects measured gait variables before and after the test using G-walker. Result: The visual feedback group showed a significant decrease (p<.05) in the number of steps per minute, walking speed, and step length compared with that of normal walking. The auditory feedback group showed a significant decrease (p<.05) in the number of steps per minute, walking speed, and step length than that of normal walking. Conclusion: The results of this study suggest that visual and auditory stimulation applied to healthy adults may have significant effects on walking.

Background: The purpose of present study was to examine the effect of ultrasound therapy and static stretching on hamstring length and balance. Design: Randomized Controlled Trial. Methods: A total of 30 adults in S college, Seongnam city, Gyeonggi-do, between the ages of 20-30 were randomly assigned to two groups. Group 1 (n=15) had ultrasound therapy, called US group. Group 2 (n=15) had static stretching, called SS group. Measurements were taken prior to starting the program and after completing the experiment using Finger to floor test and Active knee extension test to get the results of hamstring flexibility and the ability of static balance. Paired t-test was used to compare each group pre-test values to post-test values and to compare US post-test values to SS post-test values on PASW 18.0. Results: 1) Both hamstring SS group and US group had significant increase (p<.05) in Finger to floor test and Active knee extension test. 2) Dominant leg standing had significant change (p<.05) only in US group. 3) There was no significant difference between US group and SS group. Conclusion: Results showed that US group and SS group had an effect on changes in hamstring length (p<.05). However, they did not show a significant increase in static balance. Further effective studies on hamstring SS group and US group were needed based on this examination.

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.

This study is aimed at investigating the influence of different quantitative knowledge of results on the measurement error during lumbar proprioceptive sensation training. Twenty-eight healthy adult men participated and subjects were randomly assigned into four different feedback groups(100% relative frequency with an angle feedback, 50% relative frequency with an angle feedback, 100% relative frequency with a length feedback, 50% relative frequency with a length feedback). An electrogoniometer was used to determine performance error in an angle, and the Schober test with measurement tape was used to determine performance error in a length. Each subject was asked to maintain an upright position with both eyes closed and both upper limbs stabilized on their pelvis. Lumbar vertebrae flexion was maintained at $30^{\circ}$ for three seconds. Different verbal knowledge of results was provided in four groups. After lumbar flexion was performed, knowledge of results was offered immediately. The resting period between the sessions per block was five seconds. Training consisted of 6 blocks, 10 sessions per one block, with a resting period of one minute. A resting period of five minutes was provided between 3 blocks and 4 blocks. A retention test was performed between 10 minutes and 24 hours later following the training block without providing knowledge of results. To determine the training effects, a two-way analysis of variance and a one-way analysis of variance were used with SPSS Ver. 10.0. A level of significance was set at .05. A significant block effect was shown for the acquisition phase (p<.05), and a significant feedback effect was shown in the immediate retention phase (p>.05). There was a significant feedback effect in the delayed retention phase (p<.05), and a significant block effect in the first acquisition phase and the last retention phase (p<.05). In conclusion, it is determined that a 50% relative frequency with a length feedback is the most efficient feedback among different feedback types.

Purpose: This study was conducted to evaluate the effects of neck and trunk stabilization exercise on static and dynamic balance in older adults. Methods: A total of 30 older adults participated in this study. Participants were randomly assigned to the neck and trunk stabilization exercise group (NTSG) (n=15) or the trunk stabilization exercise group (TSG) (n=15). The NTSG performed a trunk stabilization exercise added to a neck stabilization exercise that included biofeedback. Both groups received training for 30 minutes per day three times per week for eight weeks. The anterior, posterior limit of stability and sway length was used to measure static balance ability, while the timed up and go (TUG) test was used to measure dynamic balance ability. Results: Participants showed significant differences in sway length, anterior limit of stability, posterior limit of stability, and the results of the TUG test between their pre- and post mediation evaluations (p<0.05). The NTSG showed a more significant increase than the TSG (p<0.05). Conclusion: According to the results of this study, both exercises effectively improved static and dynamic balance ability. However, the neck and trunk stabilization exercise is more efficient for increasing the balance ability of older adults.
