Background: Static hamstring stretching exercises have been widely used to improve flexibility of the hamstring muscles. However, few studies have examined the influence of standing static hamstring stretching (e.g., jack-knife stretching) on movements of the lumbopelvic-hip complex. Objectives: To examine the short-term effects of jack-knife stretching on movements of the lumbopelvic-hip complex. Design: Case series. Methods: Fourteen participants with hamstring tightness (8 male, 6 female) were recruited. Participants performed jack-knife stretching for 150 s. Before and after stretching, participants performed the finger-to-floor distance (FFD), sit and reach (SRT), active knee extension (AKE), passive straight leg raising (PSLA), and active straight leg raising (ASLR) tests as well as pelvic tilt while standing to identify the effects of stretching. Results: There were significant improvements in the FFD, SRT, AKE, PSLA, and ASLR tests after stretching. However, pelvic tilt angle while standing did not significantly change. Conclusion: Jack-knife stretching can be a useful exercise to improve flexibility of the hamstring muscles, but not pelvic alignment while standing.

PURPOSE: The purpose of this study were to determine an intervention that involves proprioceptive exercises combined with cognitive task completion for adults with chronic ankle instability and to investigate the effects of the exercises on the static balance, dynamic balance, and ankle function of such individuals. METHODS: A total of 30 adults suffering from the aforementioned condition were randomly divided into experimental (n=15) and control (n=15) groups. The experimental group performed proprioceptive exercises in combination with cognitive tasks for 15 minutes in each session that was held three times a week for four 4 weeks, whereas the control group carried out only proprioceptive exercises. A Wii Balance Board, which enables examining the fluctuation area distance, and speed, was used to determine static balance; a Y-balance test kit was employed to measure dynamic balance; and the side hop, figure-of-8 hop, and square hop tests were conducted to ascertain ankle function. RESULTS: The results showed that the static balance, dynamic balance, and ankle function of both the experimental and control groups significantly improved. The participants were instructed to perform one-leg postural exercises with and without vision blocking for the affected leg. The experimental group showed more significant improvement than did the controls in terms of the fluctuation distance, speed, and area of static balance. CONCLUSION: In conclusion, although combined proprioceptive exercises and cognitive tasks were insufficient to enhance all types of balance among the subjects, it effectively reinforced their static balance.

Background: To evaluate the influences of Eye movement program applied to elderly people on static balance. Methods: The subjects consisted of fourteen elderly people. The subjects were divided into two group. The control group (n=7) received no exercise and/or stimulation. The Eye movement program training (E/P) group (n=7) performed balance training using word card and batom. E/P group were accomplished during 4weeks (5 day/week, 60 min/day). All tests were completed before and after experiment. The static balance ability was measured by normal standing when eye open and close on good balance system, respectively. For each case, the experimental data were obtained in 3 item; mean X speed, mean Y speed and velocity moment. Results: The result of this study were as follows: 1. In E/P group, the statistically significants were shown on only mean Y speed in the case of normal standing when eye open (p<.05), but the statistically significants were not shown on mean X, Y speed and velocity moment in the case of normal standing when eye close (p>.05). 2. In control group, the statistically significants were not shown on all posture (p>.05). 3. There was a statistically significant difference on the mean Y speed and velocity moment in the case of normal standing when eye open between control group and E/P group (p<.05). Conclusions: The above results revealed that balance training using Eye movement program were partly effective for improving the static balance ability.

Purpose: This study aimed to compare the lasting effects of the flossing band technique, dynamic and static stretching on hamstring on range of motion (ROM), muscle activity, and proprioception to identify the most effective pre-exercise method for preventing injuries. Methods: Thirty participants were randomly assigned to the flossing band (FB), dynamic stretching (DS), and static stretching (SS) groups, with 10 subjects in each. Measurements included muscle activity of the biceps femoris vis surface electromyography, knee ROM and proprioception during active knee extension and flexion using a smart joint goniometer. Assessments were conducted before, immediately after, 15, and 30 minutes after each intervention. Results: Proprioception showed no significant differences among groups at any time point. Significant differences in knee ROM were observed in the FB group (except between 15 and 30 minutes after), DS group (except between immediately after and 15 minutes after, and between 15 and 30 minutes after), and SS group (except between before and 15 minutes after, and between before and 30 minutes after). Muscle activity in the FB (except between before and 30 minutes after, and between 15 and 30 minutes after) and SS (between before and immediately after, between immediately after and 30 minutes after, and between 15 and 30 minutes after) groups showed significant differences, while the DS group exhibited no significant changes. Conclusion: Although direct comparisons did not establish superiority, within-group analyses indicated that the flossing band technique exhibited longer-lasting effects than dynamic and static stretching, providing valuable insights for injury prevention program design.

Objective: This study aimed, first, to develop core strength training equipment with elderly-friendly, easy-to-use features and, second, to investigate the effect of core strength training using the equipment on the performance and stability of the elderly in activities of daily living. Method: In this study, we developed training equipment with a stability ball that can be used for performing core strength exercises in the elderly. Twenty-three elderly subjects (age: $77.87{\pm}6.95years$, height: $149.78{\pm}6.95cm$, and weight: $60.57{\pm}7.21kg$) participated in this study. The subjects performed the core strength training exercise with 16 repetitions for 8 weeks (2 repetitions per week). Performance in activities of daily living was assessed by using the Short Physical Performance Battery (SPPB), a test of going up and down 4 stairs, and one-leg static balance test. Stability was quantified as changes in the center of pressure (COP) and C90 area. Results: With the core strength equipment, trunk core strength exercise could be performed by pulling or pushing a rope with 2 hands on the stability ball. During the task, the tension in the rope was manipulated by a motor connected to the rope and the COP of the subject was measured by 4 load cells mounted in the equipment. Our results showed that the SPPB score was significantly higher (p < .05), the time to complete the "going up and down 4 stairs" test was significantly shorter (p < .05), and one-leg static balance statistically improved under an eyes-open condition (p < .05) after as compared with before the core strength training. The changes in the COP in the anteroposterior and mediolateral directions, and C90 area were significantly lower in the posttest (p <. 05) than in the pretest. Conclusion: The core strength training exercise using the equipment developed in the present study improved the performance and stability of the elderly in activities of daily living.

Purpose : The purpose of this study was to find out The effect of Low back pain on the total pattens of Proprioceptive neuromuscular facilitation(PNF). Methods : The subjects of the study were 62 low back pain patients. They were divided into two groups: 31 in the experimental group and 31 in the control group. the experimental group performed modalities and PNF total patterns three times for a week. the control group performed only modalities and ROM exercise three times for a week. Back muscle strength was measured by a back muscle strength measuring machine, the intensity of pain was measured by the Visual Analogue Scale (VAS), and the level of disability was measured by Oswestry low back pain disability index. Study measurements were compared before and after 6 weeks exercise program. The two groups of subjects were assessed by utilizing two different balance measurement: Static standing balance was measured by balance performance monitor (BPM) and Dynamic standing balance was measured by one leg standing(OLS). The scale for static standing balance was measured by using, sway area, sway path, max velocity. Results : The results of this study were as follow: 1) The score on visual analogue scale shows statistically significant increase on PNF group of post test(p<.05). 2) The score on Oswestry low back pain disability index. shows statistically significant decrease on PNF group of post test(p<.05). 3) The change sway area was statistically significant on pre-test and post-test(p<.05). 4) The change sway path was statistically significant on pre-test and post-test(p<.05). 5) The change max velocity was statistically significant on pre-test and post-test(p<.05). 6) The score on one leg standing shows statistically significant increase on PNF group of post test(p<.05). Conclusion : These results of this study indicated that Proprioceptive Neuromuscular Facilitation Total patterns which performed for six weeks had a statistically significant influence on low back pain. If the exercise for muscle strength is performed along with therapeutic stabilizing exercise, a better effect can be expected on low back pain. We hope that this study will provide a basic data for further research with a bigger group and on a long-term effect.

Objective: Pilates is a low/mid-intensity exercise that can be easily performed by elderly individuals as it is an individual body-oriented exercise. It is also a cardio workout that can be performed anywhere to develop strength and flexibility. Therefore, we investigated the effects of 8 week Pilates program on the balancing ability of elderly individuals. Method: The research participants were selected from elderly residents in B city. Ten individuals voluntarily signed an agreement to undergo free measurements as well as to participate in the workout program. (Height: $157.1{\pm}11.9cm$, Weight: $61.7{\pm}8.0kg$). The Pilates exercise was performed 60 minutes a day, three times a week for a total of eight weeks. The measurement variables used to test balance were the vestibular test, 5 m habitual and maximum walk test and 3 m tandem walk test. A series of paired t-test were conducted using IBM SPSS Statistics 23.0 to analyze all the research data collected in order to determine the balance ability of the participants before and after the Pilates program. Additionally, the statistically significant level for all analysis was set to ${\alpha}=.05$. Results: In the vestibular test, some meaningful changes were observed in the length envelope area (ENV) while standing on one foot, but there were no significant differences in the ENV, rectangle(REC), root mean square, and total length. Results also revealed that statistically significant differences existed in the 5 m habitual and maximum walk test, as well as the 3 m tandem walk test. Conclusion: To summarize the findings, the 8 week Pilates program employed in this study significantly improved the dynamic balance of the elderly participants. Thus, elderly individuals that frequent perform Pilates are expected to enjoy positive benefits such as increased balance and fewer falling accidents.
