PURPOSE: The purpose of this study was to investigate the effects of stretching and elastic band exercise on the knee space distance and plantar pressure distribution in people with genu varum. METHODS: The subjects of this study were students of a college who had genu varum of 14 subjects. The subjects were randomly divided into two groups as a stretching group (n=7, 4 males and 3 females, age: $20.14{\pm}2.54years$, height: $167.1{\pm}9.78cm$, weight: $58.6{\pm}10.13kg$) and a Thera-band group (n=7, 5 males and 2 females, age: $19.85{\pm}2.04years$, height: $166.5{\pm}5.82cm$, weight: $54.2{\pm}5.59kg$). The stretching and the There-band exercises were performed three times per a week, for four weeks. We measured changes in plantar pressure during walking, using a Gait Analyzer and distance of both knees at pre and post-intervention. RESULTS: These results suggest that the space distance of both knees showed differences before and after the intervention. The plantar pressure distribution was no changes in both groups before and after the intervention except for the left foot in a stretching group. CONCLUSION: As a result, the space distance of knees in both groups was significantly reduced. These result suggested that the Thera-band and stretching exercises were effective ways in alleviating genu varum.

This study was carried out to identify how a self-stretching exercise program affects pain for each body area, pain relief and job satisfaction for care workers. 20 of 40 care workers with musculoskeletal symptom were randomly selected and participated a self-stretching exercise program consisting of 15 motions. The intervention was done five times or more per weeks for 8 weeks and 1 session lasted within 15 minutes. 'Musculoskeletal symptom survey table' of the Korea Occupational Safety and Health Agency(KOSHA) and JDI(Job Descriptive Index) was used for pain on the musculoskeletal symptom and job satisfaction. Survey were done twice before and after the program. The result of this study showed that self-stretching exercise program group(SSPG) relieved from pain significantly in the shoulders(p<.01) and lumbar(p<.05), comparing to the non self-stretching exercise program group(NSPG). Although no significant difference on variations in the JDI appeared in SSPG, the significant reduction appeared from the colleague relationship and organization in NSPG(p<.05). SSPG showed the significant increase on variations in JDI from the job and organization comparing to NSPG. Especially, the improvement on satisfaction for the organization was shown(p<.05). Accordingly, the self-stretching exercise program for care workers can be said to positively affect the overall pain relief and increase on the JDI.

The purpose of this study was to identify the effects of two types of stretching extensor carpi radialis on the visual analog scale (VAS), pressure-pain thresholds (PPTs), grip strength (GS), and strength of wrist extensor (SWE) in patients with lateral epicondylalgia. Sixteen patients with lateral epicondylalgia were recruited for this study and randomly assigned to two groups; the conventional stretching group (CS) and the stretching of proximal functional massage group (PFM); the VAS, PPTs, GS, and SWE were measured before and after the intervention. Over a period of stretching exercises were performed for five minutes per day, five days per week. The paired t-test and Wilcoxon signed-rank test were used to determine the statistical differences in the VAS, PPTs, GS, and SWE (pre- and post-test). The Independent t-test and Mann-Whitney U test were used to compare the effects of stretching exercises between the CS and PFM groups. The results of this study demonstrated that in the PFM group, the PPTs, GS, and SWE significantly increased, and the VAS decreased (p<.05). In the CS group, the VAS and GS increased significantly after the three-week intervention (p<.05). Pain was decreased and strength (GS and SWE) was increased in the PFM group, compared to the CS group (p<.05). The findings of this study indicate that PFM technique can be applied for decreasing pain and increasing the GS and SWE in patients with lateral epicondylalgia.

Purpose: Flexibility has been considered one of the most important goals in rehabilitation. This study aimed to investigate the effect of transcutaneous electrical nerve stimulation (TENS) with the static stretching technique on the flexibility of hamstrings. Methods: Twenty-four subjects (15 men, 9 women) with limited hamstrings flexibility received three different intervention sessions in random order. The treatment sessions included static stretching (SS), static stretching with motor-level TENS (SS with motor TENS) and sensory-level TENS (SS with sensory TENS). All sessions of SS were performed in the straight-leg raise position for 30 seconds followed by rest for 15 seconds, in repetitions for 10 minutes using a belt. The TENS groups underwent TENS stimulation ($40{\mu}s$, 100 Hz) during the stretching for 10 minutes. Outcome measures were evaluated according to active knee extension (AKE) and recorded before the session and at 0, 3, 6, 9, and 15 minutes after the session. Results: There was significant improvement in hamstrings flexibility within all groups (p<0.05). SS with TENS (both sensory and motor) maintained significant increases in knee extension range of motion until 15 minutes post-treatment. In contrast, the SS-only group maintained significantly increased hamstrings flexibility only until 6 minutes post-treatment (p<0.05). Conclusion: Improvement in hamstrings flexibility with SS with TENS was maintained longer than with SS-only intervention. Electrical stimulation with stretching may be more effective than SS alone for increased duration of maintained hamstrings flexibility.

Purpose : The purpose of this study was to investigate the effects of flexibility and foot pressure on stretching exercise of hamstring muscle with and without pelvis neutral position. Methods : This study was performed on 30 subjects. Thirty subjects were divided into two group; hamstring passive stretching exercise with pelvis neutral position(n=15), hamstring passive stretching exercise without pelvis neutral position(n=15). Both of the group performed the exercise 4 times a week for 6 weeks. The data was analyzed by the paired t-test for comparing before and after changes of factors in each group and the independent t-test for comparing the between groups. Results : The results were as follows. There was statistically significant difference of before and after hamstring flexibility, foot pressure in pelvis neutral position(p<0.05). There was statistically significant difference of before and after hamstring flexibility, foot pressure without pelvis neutral position group(p<0.05). There was no statistically significant difference of between the two group in hamstring flexibility, foot pressure(p>0.05). Conclusion : As a result of this study, though no statistically significant difference of the between groups, we suggest that stretching exercise of hamstring muscle with pelvic neutral may be effective more than stretching exercise of hamstring muscle without pelvic neutral in flexibility, foot pressure.

Background : Patients with frozen shoulder have pain and limited range of motion (ROM) at the affected shoulder. Shoulder pain of these patients usually decreases with recovery of range of motion. The aim of this study is to identify effects of static stretching and hold-relax on recovering ROM and reducing pain of patients with frozen shoulder. Methods : In this study, 15 patients with frozen shoulder who were only treated with physical therapy were recruited. Patients who received any surgical procedure or hydrotherapy were excluded. The subjects were divided randomly into 3 groups; control(n=5), static stretching(n=5) and hold-relax(n=5) groups. Patients were treated with stretching and the total number of treatments was 12 times. The ROM was measured at baseline, after fourth, eighth and final treatments. Shoulder pain and disability index(SPADI) scores were assessed before and after doing all treatments. Repeated measures ANOVA was used to analyze ROM change within each group. Changes of ROM between groups was analyzed by one way ANOVA followed by post hot analysis(Tukey's HSD). SPADI score within each group analyzed using Wilcoxon signed ranks test. A p-value<0.05 was considered statistically significant. Study Design : Repeated measures design. Result : There were significant differences of ROM in both treatment groups except internal rotation of static stretching group. ROM was significantly increased in treatment groups compared with control group, but the difference of ROM change between two treatment groups did not differ significantly. SPADI scores for treatment groups significantly decreased compared with pre-SPADI score. Conclusion : The result suggests that hold-relax can be more effective than static stretching to recover range of motion and alleviate shoulder pain on patients with frozen shoulder.

Background: A tight iliotibial band (ITB) may lead to lateral patellar maltracking, compression, and tilt, and dominant vatus lateralis (VL) muscle activation relative to vastus medialis oblique (VMO) can laterally displace the patella, which leads to anterior knee pain. Therefore, an effective management technique is needed to stabilize the patella in individuals with tight ITB. Increased stability during the modified Thomas test has the potential to decrease compensatory motion and thus to selectively stretch the ITB. Objects: The purpose of this study was to determine the effects of ITB stretching in the modified Thomas test position on ITB flexibility, patellar translation, and muscle activities of the VMO and VL during quadreceps-setting (QS) exercise in individuals with tight ITB. Methods: Twenty-one subjects with tight ITB were recruited. Digital inclinometer was used to measure the hip adduction angle during the modified Ober test. Universal goniometer was used to measure the hip abduction angle during the modified Thomas test. Ultrasonography was used to measure the patella-condylar distance. Electromyography was performed to collect data of muscle activities. Paired t-test was used to determine the statistical significance between pretest and posttest. Results: The range of hip adduction in modified Ober test increased (p=.04) and the range of hip abduction in the modified Thomas test decreased after ITB stretching (p<.01). There was no difference between lateral patellar translation (p=.18). VMO muscle activity significantly increased after ITB stretching during QS (p<.01). VL muscle activity had no difference after stretching. Conclusion: The ITB stretching in the modified Thomas test position can be suggested as a management method for improving ITB flexibility and VMO muscle activity in individuals with tight ITB.

Purpose: This study is an investigation of the effects of long-term smart phone usage and of stretching on muscle stiffness, concentration, and visual acuity. Methods: Forty healthy young adults voluntarily participated in the study and were measured for muscle stiffness, concentration, and visual acuity before smartphone usage and after 30 minutes, 60 minutes, and 90 minutes of smartphone usage. The participants were randomly allocated to the intervention group (n=20) and the control group (n=20). Five minutes after the stretching exercise and eye exercise intervention, the participants were remeasured. Results: After long-term smartphone usage, increases in muscle stiffness and concentration were statistically significant (p<0.05), whereas decreases in visual acuity were statistically significant (p<0.05). After the stretching exercise and eye exercise intervention, muscle stiffness significantly decreased (p<0.05) and visual acuity significantly increased (p<0.05). Concentration, according to the stretching exercise and eye exercise intervention, showed no significant pre- or post-test difference. Conclusion: The results from this study indicate that long-term smartphone usage effectively improved concentration but increased muscle stiffness and decreased visual acuity. Appropriate stretching and eye movement during long-term smartphones usage should mitigate the effects on muscle stiffness and visual acuity. Furthermore, smartphones should be considered an effective tool for concentration training when coupled with the development of appropriate applications.
