Purpose : Most of the moderns have been spent sedentary life style in front of desk or on the chairs, so that their hamstring muscles are shorted commonly and the shortness of hamstring muscles are caused to some problems in functional activities. The purpose of this study was to compare the effectiveness of thermotherapy with hot-pack and ultrasound on the tightness of hamstring muscles in individuals with hamstring tightness. Method : Twenty-eight persons with hamstring tightness participated in this study. They were randomly assigned to three exercise groups: stretching group(n=10), hot-pack group(n=9), and ultrasound group(n=9). Before experiment, this study measured the angle of hip flexion using a inclinometer in all participants. Stretching group conducted actively stretching on their shorted leg for 30 seconds, 3 times, and rest for 10 seconds between each exercises. Hot-pack group have applied hot-pack($70{\sim}75^{\circ}C$) on shorted hamstring muscles for 20 minutes before stretching exercise. Ultrasound group have applied therapeutic ultrasound(1 MHz and 1.5W/cm2) on shorted hamstring muscles for 10 minutes before stretching exercise. All data was analysed using one-way repeated ANOVA. Result : The results revealed that ultrasound therapy before stretching is more effective to the flexibility on hamstring muscles than hot-pack before stretching and stretching only. Conclusion : The results of this study show that thermotherapy with therapeutic ultrasound will be effective on the shortness of hamstring muscles before stretching exercise.

Purpose: This study examined the effects of local vibration using a massage gun on the triceps surae flexibility by measuring the ankle dorsiflexion range of motion (ROM) compared to static stretching in healthy adults. Methods: Twenty healthy subjects were instructed in this study. They were allocated randomly to two groups: local vibration (LV) and static stretching (SS). The ankle dorsiflexion ROM was measured before and after the intervention in supine (open kinetic chain, OKC) and standing (closed kinetic chain, CKC). The LV group received local vibration using a massage gun for five minutes on their triceps surae, and the SS group stood on the Q board with a dorsiflexed ankle for five minutes. The ROM between pre- and post-intervention and the change in ROM between two groups were analyzed. A paired t-test was used to compare the ROM between pre- and post-intervention, while an independent t-test was used to compare the change in ROM between the two groups. Results: Both groups showed a significant difference between pre- and post-intervention in the position of both the OKC and CKC. The change in ROM, however, was not significantly different between the two groups. Conclusion: The application of local vibration using a massage gun for five minutes on the triceps surae could improve its flexibility as much as the application of static stretching. A massage gun for the application of a local vibration stimulus may be effective, simple, portable, and comfortable.

Background: The purpose of this study was to compare the effects of IASTM and static stretching techniques on ankle joint range of motion (ROM), static foot pressure. Methods: Twenty four subjects with gastrocnemius shortness participated in this study. The subjects were assigned randomly to one of two groups: The soft tissue mobilization technique (IASTM) group received intervention using a IASTM instrument for two minutes, and the stactic stretching group performed self stretching for 30 seconds, four times. The ROM of the ankle joint was measured by active ankle dorsi-flexion test, and a TPScan was utilized to collect the plantar foot pressure. This experiment was performed by two physical therapists. The significant level was set at ${\alpha}=.05$. Results: The results were as follows: 1) The ROM of the ankle joint and was significantly increased in both groups. 2) Plantar foot pressure was no significant in both groups. 3) There were no significant differences between the IASTM group and static stretching group for any variable. Conclusions: The results of this study suggest that static stretching is an effective and easy technique for restoring proper muscle length in subjects with gastrocnemius shortness. We recommend that static stretching technique be used for treat gastrocnemius shortness in clinical setting and home program.

The purpose of this study was to investigate the effects of strengthening and stretching exercises on forward head angle and static dynamic balance ability. 21 adults with the forward head posture were participated in this study. Subjects were randomly assigned to strengthening exercise group I(n=11) and stretching exercise group II (n=10) respectively. Each group were underwent six intervention over the period of 2 weeks, each session lasting 30 minutes. During a preliminary examination, forward head angle and static dynamic balance were measured, and a post examination was conducted that involved same procedure as preliminary examination. There were significant differences in forward head angle after exercise in both groups. In the strengthening group, center of gravity total sway distances was significantly changed under all conditions. In the stretching group, center of gravity total sway distances was significantly changed when subjects had their eyes open while standing on an foam surface. There were significant changes in center of gravity sway velocities in the strengthening group under all conditions, and the same was true in the stretching group only when the subjects had their eyes open while standing on an foam surface. In the comparison between groups, eyes closed while standing on a firm surface was significantly different. There was a significant difference in dynamic balance of the stretching group when the subjects tilted their bodies forward, and there was a statistically significant difference between groups under the same condition. The results of this study suggest that forward head posture can be corrected through therapeutic exercise, and muscle strengthening exercise more effective in improving static balance of forward head posture more than stretching exercise.

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.

Shoulder joint pain is a very common musculoskeletal disorder, in which about 20 percent of adults experience it more than once in their lives. In this study, an objective assessment was made that subacromial space was increased by pectoralis minor stretching exercise, which has a positive effect on impingement syndrome and shoulder pain. Also, This study examined the effects on pectoralis minor length(PML) and acromio-humeral distance(AHD) following pectoralis minor self-stretching exercise in normal adults. In this study, a total of 30 subjects were recruited and randomly divided into a self-stretching exercise group(n=15) and manual stretching exercise group(n=15) to compare the immediate effects of treatment. Studies have shown that both groups have significantly increased both PML and AHD within the group(p<.05). There was no statistically significant difference in the comparison between the groups(p>.05). The results suggest that self-stretching exercise can be recommended as a treatment method for impingement syndrome and prevention of shoulder disease.

Purpose: The purpose of this study was to investigate the effect of chest mobilization and stretching exercises on maximal inspiratory pressure and maximal expiratory pressure in healthy adults who use computers for extended periods of time each day due to coronavirus disease 2019. Methods: Twenty-five healthy adults in their 20s and without respiratory disease (15 female, 10 male) took part in this study. Two types of thoracic mobilizing exercises using a Theraband and three types of stretching exercises using a foam roller were performed. Maximum inspiratory pressure and maximum expiratory pressure were measured three times each before and after the interventions. In terms of statistical methods, the maximum inspiratory pressure due to chest mobility and stretching was compared with the maximum expiratory pressure using parametric paired t-test and non-parametric Wilcoxon signed-rank test. Results: Maximum inspiratory pressure (p = .012) and maximum expiratory pressure (p = .006) showed significant differences before and after chest mobilization exercise and stretching among the participants. Conclusion: The results of this study suggest that chest mobilization and stretching exercises are effective exercise methods for improving maximal inspiratory and expiratory pressure. They suggest that these exercises can prevent respiratory muscle weakness and improve aerobic fitness in healthy people as well as those in need of cardiorespiratory physiotherapy.

BACKGROUND: This study aimed to determine the changes in muscle strength and walking ability in patients who complained of knee instability due to excessive pronation of the foot. METHODS: Twenty patients (ten men and ten women) who complained of instability of the knee joint due to excessive pronation of the foot participated in the experiment. In the experimental group, the internal rotation of the tibia caused by excessive adduction of the foot was maintained as external rotation, and the joint state was to recognize the movement of the joint position changed through maintenance of the muscle. This exercise was performed five times for each patient, and the muscle strength maintenance was performed for 20 seconds. In the control group, stretching and range of motion (ROM) exercises were performed. For the stretching exercise, one specific motion was performed for 20 second, and the ROM exercise was performed to confirm the change in muscle strength in the knee joint area and walking ability. RESULTS: The knee flexion and extension strength in the patients with excessive pronation of the foot differed significantly from those in the subjects from the control group (p<.05). Further, the before-after comparison of the step time and length in the evaluation of walking ability, which affects overall postural movement due to knee joint instability, revealed a significant difference between the experimental and control groups (p<.05). CONCLUSION: The patients that were subjected to manual therapy and ROM exercise for the knee joint showed improved knee joint muscle strength and walking ability compared to the subjects from the control group.
