Purpose: The purpose of this study was to compare the effects of stretching exercise and aquatic exercise program on flexibility, pain and quality of life (QoL) in patients with osteoarthritis. Methods: Fifty elderly women were assigned either to the stretching exercise (SEG, n=25) or to the aquatic exercise groups (AEG, n=25) after 6-week self-help education program. SEG carried out supervised stretching exercise and water exercise training program was conducted by AEG (60 min/day, 2 days/wk) for 8 weeks. Flexibility, pain, and quality of life were measured by Senior Fitness Test Manual (Rikli & Jones, 2gr5), pain rating scale (0-10) and the questionnaire by World Health Organization Quality of Life BREF (Min et al., 2gr0), respectively. Results: Both SEG (all, p&H;.05) and AEG (all, p&H;.05) increased left upper and lower-body flexibility, measured by a measuring tape. Pain significantly decreased both in SEG (p=.000) and AEG (p=.004). Quality of life was significantly improved only for the SEG. Conclusion: The 8-week stretching exercise program would significantly improve flexibility, pain control and QoL in patients with osteoarthritis.
To investigate the effects of stretching and temperature of pre-rigor muscle on sarcomere length and tenderness of beef, hot boned M. Iongissimus dorsi thoracis were stretched or non-stretched, and stored at $0^{\circ}C$ for 48 hrs ($0^{\circ}C$ stretched and $0^{\circ}C$ non-stretched) or at $10^{\circ}C$ for 7 hrs followed by $0^{\circ}C$ for 41 hrs ($10^{\circ}C$ stretched and $10^{\circ}C$ non-stretched). There was no significant difference in muscle pH and drip loss between $10^{\circ}C$ stretched and $10^{\circ}C$ non-stretched samples, but they were significantly (p<0.05) lower in pH and drip loss than $0^{\circ}C$ stretched and $0^{\circ}C$ non-stretched samples. Stretched muscles at $0^{\circ}C$ showed significantly (p<0.05) higher cook loss than control muscles. Sarcomere length of $10^{\circ}C$ stretched muscle was significantly (p<0.05) longer than that of control. However, control muscle showed significantly (p<0.05) higher value of shear force at 2 and 14 days postmortem compared to that of $10^{\circ}C$ stretched muscle. Panels rated $10^{\circ}C$ stretched muscle as having a significantly (p<0.05) better tenderness, flavor and overall acceptability compared to those of control muscle. Results suggest that longer sarcomere length and tender beef could be obtained by stretching of pre-rigor muscle and storing it at $10^{\circ}C$ for 7 hrs followed by $0^{\circ}C$ for 41 hrs.
The purpose of this study was to prove the effect of passive stretching after delayed muscular pain induction in university students and to propose a rehabilitation exercise program for effective pain relief and prevention in case of injury. Subjects were divided into passive stretching group and control group. Passive stretching group was performed passive stretching after delayed muscular pain induction and control group did not perform any treatment after delayed muscular pain induction. The delayed muscular pain induction method was induced by bench step motion. The height of the step box was 50cm. The data were analyzed by two-way RGRM ANOVA for comparison of passive stretching group and control group. In conclusion, passive stretching after delayed myalgia has a positive effect on blood fatigue (CRP, LDH) and subjective pain scale(VAS).
The purpose of this study was to investigate the fusion effects and difference them of the deep transverse stroking, manual stretching exercise and active muscle release technique on psoas major muscle thickness and muscle tone, and pelvic angle in non-specific low back pain patients. Psoas major muscle thickness was significantly decreased after the application of the deep transverse stroking $0.19{\pm}0.16cm$ (p <0.05), manual stretching exercise $0.18{\pm}0.14cm$ (p <0.05), and active muscle release technique $0.43{\pm}0.35cm$ (p <0.05). The pelvic angle was significantly decreased after the application of the deep transverse stroking $4.48{\pm}1.63^{\circ}$ (p <0.05), manual stretching exercise $5.36{\pm}2.04^{\circ}$ (p <0.05), and active muscle release technique $7.24{\pm}2.23^{\circ}$ (p <0.05). The Psoas major muscle tone was significantly decreased after application of the deep transverse stroking $0.96{\pm}0.93Hz$ (p <0.05), but manual stretching exercise $0.87{\pm}1.20Hz$ (p> 0.05) and active muscle release technique $0.82{\pm}0.98Hz$ (p> 0.05) there was no significant difference after application. There were no significant differences between the three intervention methods in the pelvic angle and psoas major muscle thickness and tone changes. In order to change psoas major muscle thickness and pelvic angle, three intervention methods should be applied appropriately according to the condition and environment of the patient, and deep transverse stroking is more effective for changing psoas major muscle tone.

PURPOSE: This study compared the effect of the muscle energy technique (MET) and stretching technique on ankle dorsiflexion passive range of motion, balance, and gait ability of stroke patients with limited ankle dorsiflexion. METHODS: Forty-four post-stroke patients participated. The participants were randomized into the MET group (METG; n = 22) and the stretching group (STG; n = 22). The METG was subjected to the MET to relax the dorsiflexion, while the STG was subjected to the dorsiflexion stretching technique. Both groups completed standard neurological physical therapy for 30 min per session. The intervention was conducted five times a week over 3 weeks for a total of 15 times. All participants underwent ankle dorsiflexion passive range of motion measurement and Berg Balance Scale score determination and completed a 10-m walking test and the timed up and go test before and after the intervention. RESULTS: After the 3-week intervention, both groups showed significant improvement after the intervention (p < .05). METG participants showed greater improvements in ankle dorsiflexion passive range of motion and 10-m walking test results compared to STG participants (p < .05). CONCLUSION: Both interventions improved ankle dorsiflexion passive range of motion, balance, and gait ability in stroke patients with limited ankle dorsiflexion. Moreover, the MET was superior to ankle dorsiflexion passive range of motion on the 10-m walking test.

Background: Repetitive damage to the ankle joint causes chronic ankle instability, and studies comparing the effects of exercise in open and closed chains as a treatment method are very rare. Objectives: To investigate the effects of open and closed kinetic exercises on muscle activity and dynamic balance of ankle joint in adults with chronic ankle instability. Design: Single-blind randomized controlled trial. Methods: The selected 30 subjects are randomly divided into open kinetic chain exercise experimental group (EGI, n=10), closed kinetic chain exercise experimental group (EGII, n=10), and stretching control group (CG, n=10). Open and closed kinetic exercises lasted 30 minutes three times a week for six weeks and stretching exercises performed four actions for 20 seconds and five sets. The measurement tools using surface electromyography to measure muscle activity in the ankle joint. The dynamic balance of the ankle was evaluated using the Y-Balance test. Results: Following the intervention, closed and open kinetic chain exercise group showed significant difference in tibialis anterior and gastrocnemius muscle activity and dynamic balance (P<.05). However, no significant difference in tibialis anterior and gastrocnemius muscle activity and dynamic balance between closed and open kinetic chain exercise group (P<.05). Conclusion: This study provides evidence that closed and open kinetic chain exercise can be presented as an effective exercise for the muscle activity of ankle muscle and dynamic balance of the subject with chronic ankle instability.
Background: The purpose of this study was to investigate the effect of stretching and strengthening exercise on the static flexibility and pain intensity for the iliopsoas muscle, which is one of the main reasons for the chronic low back pain. Methods: The subjects of this study were 15 male adult patients with showed 6 score or higher in the visual analogue scale(VAS) and complained of low back pain over three months who visited department of the physical therapy, KIA motors Industrial Health Center, from October, 2008 through December, 2008. Fifteen subjects were trained stretching, mat exercises and sling exercises for iliopsoas muscle at 4-5 times a week for 4 weeks. I measured the changes on the extensibility of iliopsoas muscle, static flexibility of low back and VAS between pre- and post exercise treatment. Date were analyzed using the Wilcoxon's signed rank test considering the size of the samples. Results: 1. The angle of the hip joint that showed the extensibility of iliopsoas muscle was relieved, which was significant statistically (p<.05). 2. The static flexibility was statistically significantly improved in the trunk flexion test, trunk extension test and Schober-Test (p<.05). 3. The VAS showed decrease, which is significant statistically (p<.05). Conclusion: It is believed that the exercise treatment of iliopsoas muscle has the significant effects on the improvement of static flexibility and decrease of pain intensity for the chronic low back pain patients.
The aims of this study were to determined whether excitability of the $\alpha$-motor neuron is modulated by stretching and this changes were associated with flexibility of the muscle. In this study, $\alpha$-motor neuron excitability was measured by using the Hmax/Mmax ratio of the gastrocnemius H-reflex, and muscle flexibility was measured with the range of motion of the ankle dorsiflexion. The gastrocnemii of 10 healthy volunteers were stretched for 4 minutes(2 minutes stretching, 1 minute rest, and 2 minutes stretching) in each session by manual force. The Hmax/Mmax ratio of the H-reflex, as well as the range of motion of the ankle dosiflexion was measured through four different conditions: before stretching, as soon as after $1^{st}$ stretching, as soon as after $2^{nd}$ stretching and at 48 hours after $2^{nd}$ stretching. Excitability of the $\alpha$-motor neuron was decreased significantly after $1^{st}$ and $2^{nd}$ stretching(p<0.05). Furthermore, the range of the dorsiflexion was increased significantly after $1^{st}$ and $2^{nd}$ stretching(p<0.05). However, the excitability of the $\alpha$-motor neuron and range of the dorsiflexion at 48 hours after $2^{nd}$ stretching were not different from those of before stretching. These results suggest that reduced $\alpha$-motor neuron excitability of the gastrocnemius and increased flexibility of the ankle dorsiflexion would be followed by activation of the type III mechanoreceptor which around the ankle joint and the Golgi tendon organ in the gastrocnemius.
Purpose : The aim of this study is to examine the effect of the phenol compound-cold therapy plus exercise therapy on the carrageenan(CAR)-induced muscle pain. Method : Mice were injected 0.1ml of 2% CAR into the gastrocmemius(GAS) muscle for the induction of muscle pain. After 4 hours from the injection of CAR, the cold therapy with 1% syringic acid was done to GAS muscle. After 2 hours from cold therapy, the exercise therapy such as muscle stretching, climing- and declining-movements was performed three times interval of 10 minutes in each experimental group. After 4, 10 and 24 hours from CAR-induced muscle pain, the measurements of muscle diameter, paw withdrawal latency(PWL) and, tail flick latency(TFL) were carried out. Results : In this study, the thickness of GAS muscle in CAR-induced muscle pain significantly increased compared with control. While, the thickness of GAS muscle adopted cold syringic acid-therapy with exercise-therapy group was significantly decreased than that of CAR-induced muscle pain. In the measurements of PWL and TFL, cold syringic acid-therapy with exercise-therapy group was remarkably increased than CAR-induced muscle pain group in PWL and TFL. All measurements were showed significantly different between the treated-group and the treated-time. Conclusions : From these results, it is suggested that the cold syringic acid-therapy with exercise-therapy such as muscle stretching, climing- and declining-movement was effective in the prevention of CAR-induced muscle pain by the decrease of muscle thickness and the increase of PWL and TFL.
Background: To prevent or reduce the risk of strain injury, various approaches, including stretching techniques are currently being used. The effect of proprioceptive neuromuscular facilitation (PNF) and static stretching on flexibility has been demonstrated; however, it is not clear which one is superior. Objects: This study aimed to evaluate the differences between the effects of PNF and static stretching performed at various intensities on muscle flexibility. Methods: The maximum voluntary isometric contraction (MVIC) of the hamstrings using the PNF stretching technique was performed in the P100 group, while 70% of the MVIC was performed in the P70 group. The MVIC value obtained during the PNF stretching in both groups was used as a reference for setting the intensity of static stretching. Static stretching was performed at 130% (S130), 100% (S100), and 70% of the MVIC (S70). The active knee extension (AKE) values, defined as the knee flexion angle were measured before stretching (baseline), immediately after stretching (post), and at 3 minutes, 6 minutes, and 15 minutes. Results: PNF stretching produce a greater improvement in flexibility compared with static stretching. Specifically, the ΔAKE was significantly higher in the S100 and S70 groups than in the P100 group at Post. In the comparison of ΔAKE over time in each group, the ΔAKE at Post showed a significant decrease compared to the value at Baseline in the S130 group; however, no significant difference was observed at 6 minutes while a significant increase was noted at 15 minutes. Conclusion: This study found that PNF stretching is more effective than static stretching with respect to increasing and maintaining the flexibility of muscles. In addition, the increase in flexibility at maximal intensity was similar to that observed at submaximal intensity during both PNF and static stretching.
