Purpose : The fascia is the body's largest sensory organ affected by mechanical stimuli such as pressure. Fascial distortion model (FDM) is one of the fascia treatment techniques, and it is based that most musculoskeletal problems are caused by three-dimensional distortion of the fascia. Until now, some studies have been conducted to investigate the effect of FDM, but it is still not enough. In this study, among the six techniques of FDM, trigger band (TB) and cylinder distortion (CyD) were applied to the forearm to investigate the immediate effect on the maximal grip strength, force sense and range of motion. Methods : 22 healthy adults in their 20s and 30s participated. Before and after the application of FDM, maximal grip strength, force sense and range of motion were measured. For analysis, a paired t-test was performed, and the significance level was set to p<.05. Results : After FDM, there were a significant differences that increased the force sense and the range of motion (p<.05). But the maximal grip strength did not show a significant difference (p>.05). Conclusion : The results of this study, the FDM did not affect maximal grip strength, but it was shown to increase the sense of force and range of motion. We assumed that it is the result of the changes in the states of the fascia and changes in the activity of mechanical receptors induced by pressure and stretch from FDM application.

Objective: Training-related injuries and attrition put an additional burden on police and military institutions. Preventing and minimizing musculoskeletal injuries is the primary concern of the Abu Dhabi Police. Therefore, this study aimed to evaluate the correlation between functional movement screen, lower-limb strength, Y-balance test, grip strength and vertical jump and the incidence of musculoskeletal injuries among Abu Dhabi police recruits. Design: Observational analytical study. Methods: An observational study was conducted on 400 male police recruits of Abu Dhabi Police Academy. Physical performance was assessed before the 16-weeks basic police training. Spearman's correlation evaluated the correlation between the performance parameters and the outcome measures and logistic regression predicted the risk factors associated with musculoskeletal injuries. Results: 149 (34.4%) participants reported at least one injury during the basic police training. Comparison between injured and non-injured participants showed significant difference in mean right Y-balance, back-leg-chest dynamometer, and vertical jump (p=0.02, p=0.02, and p=0.04, respectively). Spearman's correlation showed a significant negative correlation between risk of injury and back-leg-chest dynamometer and right Y balance (ρ= -0.11, p=0.03). Logistic regression showed that back-leg-chest dynamometer and right Y balance were significant predictors of injury (p =.036 and p=0.037; Odds ratio=0.96; 95% CI (0.92, 0.99) and Odds ratio=0.99; 95% CI (0.98,0.99). Conclusions: Our findings suggest functional movement screen and grip strength may not independently predict injury rates, balance and lower-limb strength needs to be considered in injury prevention strategies to reduce musculoskeletal injuries.

Purpose: The purpose was to determine whether the application of the abdominal drawing-in maneuver (ADIM) and abdominal expansion maneuver (AEM) to stroke patients would affects their trunk stability, balance, pulmonary function, and grip strength. Methods: The subjects were 36 stroke patients who were randomly and equally assigned to an ADIM group (n=12), an AEM group (n=12), and a control group (n=12). The intervention was applied to each group three times per week, 30 minutes each time, for four weeks. Outcome measures were grip strength, modified functional reach test (mFRT) and pulmonary function. Pulmonary function were measured force expiratory volume at one second (FEV1), forced vital capacity (FVC), FEV1/FVC and peak expiratory flow (PEF) values. Results: The results of the three groups showed statistically significant improvements in grip strength. The AEM group showed significantly greater differences in grip strength than either the ADIM group or the control group. In the anterior mFRT, the ADIM group showed significantly improvements than the control group. The ADIM and AEM groups were showed statistically significant greater improvements in PEF between the baseline and post-intervention and the post-analysis revealed that the AEM group showed significantly greater improvements than the control group. Conclusion: The results of this study indicate that the ADIM and AEM were effective in improving the PEF of pulmonary function. The ADIM was more effective than AEM in trunk stabilization.

Modern technology has lessened the physical demand of every activities. Thus, physical inactivity has led to a rise in ‘Hypokinetic diseases’. The prefix, hypo, means lack of and kinetic refers to movement. Individuals who do not exercise regularly are at greater risk of developing hypokinetic diseases such as coronary heart disease, hypertension, hyperlipidemia, obesity, musculoskeletal disease. Systematic exercise program defenses development of hypokinetic diseases. Exercise program bases on basic physical fitness test. The physical fitness evaluation is used to degree of Wellness of the individuals. It includes the evaluation of Health-Related Physical Fitness -musclular strength, muscular endurance, flexibility, cardiorespiratory endurance, body composition - and skill or sports related fitness -agility, balance, coordination, reaction time, speed. In present study, the authors investigated health-related physical fitness test result and questionnaire for 133 male and 71 female from Jannuary 16 to March 15, 1997. The purpose of this study is to observe relationship health related physical fitness and self-perceived health status. The results are as follows. 1. There were statistically significant differences in BMI, grip strength, back strength, muscular endurance, cardiorespiratory endurance, and flexibility between male and female subjects. Flexibility is higher in female than male subject, but Others are higher in male than female subjects. 2. There were statistically significant differences in grip strength, muscular endurance between 30s, 40s, and 50s group In both gender subjects, and In cardiorespiratoryendurance between the groups especially in Female subjects. 3. For male subjects, flexibilitywas measured lower in group who classified low level in self-perceived health status than group of others. Also, for female, subjects, Muscular endurance ＆ flexibility were measured. 4. It was shown that grip strength, back strength, and muscular endurance were significantly lower in group who have chronic diseases than normal group for Male subjects. But, For female subjects, all the component were statistically insignificant results between normal and disease group. 5. Both male and female subjects, there were Positive correlation among grip strength, back strength, muscular endurance, cardiorespiratory endurance, and flexibility but, negative correlation for age. Therefore, health-related physical fitness is very important component for Heath Promotion ＆ Wellness.
