PURPOSE: The effectiveness of the stretching to increase the range of motion of the joint, reduce the risk of injury, enhance athletic performance or decrease post exercise muscle soreness. This study was to compare the effect of the stretching method applied on the shortened hamstring muscle for flexibility, strength, pressure pain threshold value and muscle tone. METHODS: This study is a two-group pretest- posttest design. Fifty-four healthy young adults were randomly assigned to a vibration-assisted stretching group (VASG, n=27) or a static stretching group (SSG, n=27). Participants performed each stretch in 4 sets of 30 seconds each. A 30-second break time was provided between the sets. The range of motion, strength, pressure pain threshold values and muscle tone of the hamstring muscle were measured to compare the effects of the stretching methods. RESULTS: Both the VASG and the SSG participants showed significant improvement in the range of motion and strength (p<.05); however, the increase in the VASG was significantly higher than that in the SSG (p<.05). The pressure pain threshold values and muscle tone were significantly decreased only in the VASG (p<.05). CONCLUSION: These findings indicate that vibration-supported stretching is an effective intervention for people with hamstring shortening, with high pain level and muscle tone decrease.

Purpose : The purpose of this study was to compare the effect of three types of therapeutic exercises by applying them to lower back pain patients. Methods : This program was conducted for 30 patients 30 to 55 years old, who visited a rehabilitation center due to lower back pain. We separated participants into three groups with different therapeutic exercises: one with lumbar stabilization exercises, another with stretching exercises, and the other with both exercises. Each exercise was held once a day, 3 days a week, for 6 weeks. We analyzed the effect of these exercises by checking the change of lumbar muscle strength and pain relief. Lumbar muscle strength was measured by AS-Med and pain strength was estimated by VAS. Results : The result of the programs was established according to the following list: 1) Lumbar stabilization exercises and stretching exercises lead to higher lumbar muscle strength and pain relief (p<0.05). 2) Lumbar muscle strength in the lumbar stabilization exercise group was significantly higher than the stretching exercise group (p<0.05). 3) Pain relief in the stretching exercise group was significantly higher than the lumbar stabilization exercise group (p<0.05). Conclusion : This study shows all of the groups experienced higher lumbar muscle strength and pain relief. Specifically, there was higher lumbar muscle strength in the lumbar stabilization exercise group and higher pain relief in the stretching exercise group. Therefore the ideal intervention to improve lumbar muscle strength and pain relief for patients is to implement both lumbar stabilization exercises and stretching exercises.

The purpose of this study was to compare the effects of one proprioceptive neuromuscular facilitation technique and static stretching on calf muscle tightness. The subjects consist of 9 hemiplegics, and 9 quadriplegics. The eighteen subjects were randomly divided into 3 groups: prorioceptive neuromuscular facilitation(6 persons), static stretching(6 persons) and control(6 persons). Contract relax antagonist contract and static stretching techniques were applied continuously for twenty minutes each. Of the many proprioceptive neuromuscular facilitation techniques, only the contract relax antagonist contract technique was applied. The static stretching technique was applied with the subject placed in standing on a seventy degree inclined tilt table for twenty minutes. A wedge was placed under the feet to obtain maximum dorsiflexion. Wedge thickness varied with each subject. Results revealed: (1) a significant difference between the experimental and the control groups(p<0.05). (2) a significant difference between contract relax antagonist contract and static stretching groups(p<0.05). (3) At day five, the final increments were: contract relax antagonist contract $11.9{\pm}1.90^{\circ}$, static stretching $7.7{\pm}2.3^{\circ}$(mean${\pm}$standard deviation).

The purpose of this study is to investigate effects of Maitland orthopedic manipulative physiotherapy and stretching on pain, cervical range of motion, and muscle tone of adults with forward neck posture. A total 40 subjects were divided into a Maitland OMPT group(n=20) and a stretching group(n=20), performing joint mobilization exercise and stretching three times per week for six weeks. As for changes in pain, statistically significant decrease were found before and after the exercise within group comparison(p<.01), while no statistically significant difference was observed between-group comparison. In changes in cervical range of motion before and after the exercise, the Maitland OMPT group showed statistically significant increase(p<.01) in flexion, (left lateral flexion(p<.05), extension, left rotation, right rotation, and right lateral flexion, while the stretching group showed statistically significant increase(p<.05) in extension(p<.01), left rotation, left lateral flexion, right rotation, and right lateral flexion. However, no significant differences in between group comparison in flexion, extension, right rotation, left rotation, right lateral flexion and left lateral flexion. The results of measuring muscle tone changes showed that the Maitland OMPT group and the stretching group did not show significance in within and between group comparison(p<.05). In conclusion, the Maitland OMPT and stretching were effective on improving pain and range of motion.

본 연구에서는 폴리프로필렌을 소재로 열유도 상분리 공정과 연신공정을 적용한 복합공정을 통하여 중공사막을 제조하였다. 희석제로는 soybean oil을 사용하였고 구정의 조절을 위하여 benzoic acid를 기핵제로 사용하여 연신용 전구체를 제조하였고 이를 연신하여 다공성 중공사막을 제조하였다. 연신공정에서 연신율과 변형속도의 영향을 조사하였는데 연신율이 높을 때는 미세공의 크기가 커지면서 불균일한 미세공이 생성되었고 변형속도가 높을 때는 균일한 크기의 미세공 분포도를 보이며 미세공의 크기가 커졌다. 연신율이 증가할수록 고분자 사슬의 배향도가 높아지면서 인장강도가 향상되었고 변형속도가 높아지면서 결정성 영역의 고분자 사슬의 배향도는 변하지 않았으나, 무정형 영역의 고분자 사슬 배향도가 낮아지면서 전체적인 중공사막의 인장강도는 저하되었으며 상대적으로 약한 spherulite를 연결하는 micro-fibril이 끊어지면서 미세공의 병합이 이루어져 원형의 기공이 형성되었다.

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.
