Objective: Nonspecific low back pain (NS-LBP) causes pain and disability, affecting the neuromuscular system and altering gait patterns. The purpose of this study is to investigate the effect of improvement of low back pain symptoms through physical therapy on foot pressure and spatiotemporal gait parameters. Design: A pilot study. Methods: Participants received manual therapy and supervised therapeutic exercise, which consisted of 12 sessions for 6 weeks. Participants were assessed for pain intensity (a numeric pain rating scale), disability index (oswestry disability index), and spatiotemporal gait parameters before and after intervention. Wilcoxon signed rank test was used to analyze the before-and-after differences in a single group. Results: All seven NS-LBP patients completed the study without dropout. After six weeks of physical therapy, the numeric pain rating scale and oswestry disability index showed significant improvement (Z= -2.388, P=0.017). There was no significant improvement in both static and dynamic conditions in foot pressure (P>0.05). However, in the spatiotemporal gait parameters, there were significant differences in all variables except the right stance phase and left mid stance (P<0.05). Conclusions: In our pilot study, 12 sessions of physical therapy in NS-LBP patients improved gait quilty in spatiotemporal gait parameters. Similarly, it has resulted in clinically positive improvements in pain and disability.

This study proposed a multiple regression equation for predicting VO2max of elderly men and women using functional performance variables required to conduct daily activities. The subjects of this study were 58 elderly men (72.4±5.9 yrs) and 117 elderly women (73.4±4.5 yrs) aged 65-90 who belong to the senior welfare center. The maximal graded exercise test using a cycle ergometer and functional performance representing muscle strength, endurance, static and dynamic flexibility, mobility, and agility were measured. For statistical processing, multiple regression analysis was performed, and the statistical significance level was α = .05. As a result, the VO2max estimation formula for the elderly was 0.419 (standing up and sitting down a chair) + 0.199 (leg endurance against wall) + 5.383, and R2=0.406. In addition, the VO2max estimation formula for elderly women is - 0.737 (standing up from a supine position) - 0.144 (waking around two cones in a figure 8) - 0.135 (%body fat) + 0.042 (one leg balance with eyes open) + 29.395, R2=0.367 was calculated. The conclusion is that if the maximal graded exercise test is not available, it is considered that VO2max of the elderly can be predicted properly by using the estimation formula calculated based on the functional performance variable.

The purpose of this study was to identify the effects of a visiting exercise program for physical activity promotion on physical (grip strength, static balance) and psychological (depression, perceived health status) function of frail elderly patients receiving home visiting service care. Subjects included a total of 49 patients; 24 in the control group and 25 in the experimental group. The visiting exercise program was carried out 16 times for 8 weeks. The collected data were analyzed by ${\chi}^2-test$ and t-test using SPSS/WIN 21.0 program. There was a significant improvement in the left grip strength (t=2.19, p<.000), right grip strength (t=5.07, p=.032), static balance (t=3.98, p=.050), and depression (t=-8.83, p=.009) in the experimental group compared with the control group. The visiting exercise program for physical activity promotion was effective on physical and psychological functions for frail elderly patients receiving home visiting service care. Further research is needed in a longitudinal study incorporating various centers to examine the maintenance of such effects.

This study was conducted to investigate the effect of ankle muscle strengthening exercise using BOSU ball and taping on static and dynamic plantar pressure in patients with hallux valgus. Subjects were 26 men and women in their twenties with hallux valgus, and they were randomly assigned to a taping group (TG; n=13) and an ankle strengthening group (ASG; n=13). Each group received the appropriate intervention over a total of 4 weeks, and static and dynamic plantar pressure were measured before and after the intervention. Independent T-test was performed to examine the difference in the amount of change between groups, and paired-sample T-test was performed to determine whether the difference between the pre-post values within the group was significant. The statistical significance level was set as α=.05. As for the ratio of the total body weight of the foot (Foot), the amount of change in the ASG of the left foot was significantly decreased compared to the TG within the group (p<.05). Significantly increased (p<.05). As for the degree of pronation of the foot (MP/change ratio), the amount of change in the TG of the right foot was significantly decreased compared to the ASG (p<.05), and in the force of the foot, the TG of the left foot was the amount of change within the group compared to the ASG. was significantly increased (p<.05), and in the group-to-group change, the amount of change in TG was significantly different than that of ASG (p<.05). Therefore, it can be considered that ankle strengthening exercise using bosu ball and taping are insufficient to give effective change to patients with hallux valgus.

PURPOSE: This study evaluated an intrinsic foot strengthening exercise method for flat feet by comparing the effects of intrinsic exercises on a stable surface and intrinsic exercises on an unstable surface. METHODS: Twenty-four people with flat feet were divided into two groups. The control group performed short foot exercises and toe towel curl exercises on the stable support surface. The experimental group performed short foot exercises and toe towel curl exercises on an unstable support surface using Aerostep. The navicular drop test, and the static and dynamic balance were measured before and after the intervention. RESULTS: In the experimental and control groups, there was a significant difference in the navicular drop test and static balance before and after the intervention (p < .05). On the other hand, there was no significant difference between the two groups (p > .05). In the dynamic balance, the experimental group showed significant differences in all directions after the intervention (p < .05). The control group showed significant differences in the postero-lateral direction and posteromedial direction (p < .05). In particular, in the forward direction, the experimental group had a more significant change than the control group (p < .05). CONCLUSION: Intrinsic foot muscle strengthening exercises performed on unstable surfaces can be an effective clinical exercise method to improve the dynamic balance ability of people with flat feet.

The purpose of this study was to determine the efficient way of stretching technique from three methods, and of stretching duration and frequency. Sretching is known to improve musculotendinous flexibility and joint suppleness, and employed in many warm-up routines during physical activities and athletic performances. The benefits and the rationale of stretching have been reviewed. Many authors agree that, for the best results, static stretching has to be held for approximately 30 sec. in a trial, three trials in a session, at least three times a week for four weeks. Further clinical studies are required for elucidating more informations on this subject.

Purpose: Stretching exercises are commonly used in conjunction with sports and rehabilitation. Weassessed the immediate effects of stretching on passive stiffness of the hamstring muscles and knee range of motion (ROM) using three stretching techniques. Methods: A total of 45 participants were recruited. Isokinetic equipment was used to measure the passive stiffness of hamstring muscles and an inclinometer was used to measure active and passive ROM of the knee joint pre and post stretching. Stiffness was then calculated based on the incline of the torque-angle relationship. The test conditions for Group I were $3{\times}30$ seconds of static stretches using the hamstring muscle, Group II were $3{\times}30$ seconds of static stretches using the hamstring muscle with ankle dorsiflexion, and Group IIII had $3{\times}30$ seconds of active stretching. Results: Group II had significantly higher excursion of active ROM and Group IIIhad significantly higher excursion of passive muscle stiffness. All of the groups had significantly higher active and passive ROM and significantly lower muscle stiffness after stretching. The participants showed no change in hamstring muscle stiffness on the following day. Conclusion: Stretching has significant acute effects on ROM and muscle stiffness and canbe used in warm-up protocols for reducing muscle stiffness before a variety of exercise programs.

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.

The purpose of this study was to evaluate the effect of joint mobilization and manual stretching exercises in patients with hallux valgus. Twenty-three participants were divided into two groups; joint mobilization (n=11) and manual stretching exercises (n=12). The subjects participated in the experiment for 15minutes, three times a week, four weeks. The joint mobilization (Grade III, Maitland) was performed to experimental group for a minute and then rested for 10 seconds for each set. The manual stretching was performed to control group with three exercise session (preparatory and finishing exercises, agonist contraction exercises, agonist contraction and hold-relax exercises). In the results of the study, intragroup comparison of the deformity angles (DA) was shown to decrease from $15.18^{\circ}$ to $13.09^{\circ}$ in the joint mobilization group (p<.05) and from $19.00^{\circ}$ to $16.83^{\circ}$ in the stretching exercises group (p<.05). However, left static foot pressure (LSFP), right static foot pressure (RSFP), left dynamic foot pressure (LDFP) and right dynamic foot pressure (RDFP) did not significantly increase or decrease after the experiment. Intergroup differences also were not statistically significant in all variables (p>.05). The current study suggests that JM and MSE are effective in decreasing the DA in patients with hallux valgus.
