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.

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. Physical Fitness test is valuable test in health evaluation, health management and health promotion, so available for hospital, sports center, community health center, industrial field, school etc.

This study was conducted to develop an individualized upper extremity exercise program for patients after mastectomy and evaluate its effectiveness. A nonequivalent control-group pretest-posttest design was used for this investigation. Research participants were patients with breast cancer who underwent mastectomy at two university hospitals (experimental group, n=17; control group, n=16). The experimental group received an individualized upper extremity exercise program three times a week for 7 weeks. Data were analyzed by the ${\chi}^2-test$, Fisher's exact test, Mann-Whitney U-test and Wilcoxon Signed Rank test using SPSS WIN 21.0. Inter-group comparison revealed significant differences between pre-test and post-test in hands behind the back, flexion, abduction, external rotation, internal rotation, and grip strength. Moreover, the experimental group showed significant improvements in hands behind the back, flexion, abduction, external rotation, internal rotation, and grip strength relative to the control. In conclusion, the individualized upper extremity exercise program was shown to be an effective intervention to improve physical functions in upper limbs and shoulders. Therefore, this program should be applied to patients after mastectomy in clinics since many patients have suffered from decreased physical functions in upper extremities.

The purpose of this study was to investigate the effects of active vibration exercise of upper limb on physical capacity index (endurance, grip strength, balance, and flexibility) and vasomotor index (capillary length and body surface temperature) in middle aged women. 20 participants randomly divided into two groups: vibro-swing exercise (VSE) and non vibro-swing exercise (NVSE). Subjects in each group measured the 30 second arm curl test, hand dynamometer, one leg standing test, back scratch test, nail fold capillary microscope (NFM), and digital infrared thermal imaging (DITI) before and after exercise. The results showed that active vibration exercise of upper limb with vibro-swing equipment increased the endurance, balance ability, and the capillary length. In addition, changes in body temperature immediately after exercise were predicted to affect vasomotor. Active vibration exercise of upper limb has the advantage of being able to exercise anywhere regardless of the location by inducing different frequency changes in movement of various ranges and velocity. For this reason, the combination of vibration and active movement can be expected the physiological effects when producing exercise programs for middle aged women.

This study investigates the relationship between muscular strengths and gait characteristics of the elderly. Totally, 107 subjects, aged 65 to 85 years, participated in this study. Researchers measured muscle strengths (grip force, toe grip force, gluteus medius, and gluteus maximus forces) and walking characteristics (walking speed, cadence, step length, single leg support, and double legs support). Dynamometers and inertial measurement unit-based shoe systems were used for measuring muscular strength and gait characteristics, respectively. No significant difference was observed in strengths and walking characteristics between the young elders (YE, 65-74 years) and the old elders (OE, 75-85 years). For each age, muscular strength significantly correlated with some gait parameters. Forces of gluteus medius and gluteus maximus muscles showed better significant correlations between some gait parameters for all age groups, as compared to grip force and toe grip force. Regression coefficients between walking speed and grip force did not vary with age. We conclude that muscular strengths in OE better explained the gait characteristics than in YE subjects. Even though grip strength is an easily measured variable for senior fitness test, forces of gluteus medius and gluteus maximus muscles are more meaningful for understanding the walking characteristics of elderly people.

Traumatic reticuloperitonitis (TRP) often referred to as hardware disease is a common disease of cattle, which is considered the most frequent cause of anterior abdominal pain in cattle. The incidence of TRP has decreased significantly, but the diagnosis and treatment of TRP are still clinically significant because of its economic impact. An eight-year-old female Mongolian cow weighing 400 kg, was presented to the Korean (College of Veterinary Medicine, Jeju National University)-Mongolian (School of Veterinary Medicine, Mongolian University of Life Science) volunteer team (KMVT) with the primary complaints of depression and anorexia during their outreach activity for veterinary volunteer service in the field of the suburban farm of Mongolia. TRP was diagnosed based on the clinical symptoms, auscultation, and back grip test results. An emergency rumenotomy was performed with the consent of the owner. The patient was anesthetized using distal paravertebral anesthesia and the inverted L block method while a makeshift restraint frame was constructed on-site. The rumenotomy was performed to explore the rumen and reticulum. Foreign bodies were identified and removed. The surgery was performed successfully. The patient's recovery after the surgery was normal, and the appetite was restored. This paper describes a case of TRP in a Mongolian cow, including the diagnosis, surgical preparation, and surgery successfully performed in the field of suburban farm of Mongolia in detail.

Purpose: The purpose of this study was to investigate the differences in body composition, upper and lower limb muscle strength, and functional physical ability in urban-dwelling elderly women with or without obesity. Methods: All study participants were assigned to the normal weight group (n=8, BMI<25) and the obesity group (n=7, BMI>25) based on their obesity rate. Anthropometric measurement was conducted and body composition was measured. For the upper and lower limb strength, grip strength and maximal isometric knee extension and flexion were evaluated by a dynamometer. The senior fitness test was performed to measure functional ability. Data analysis was conducted by the independent t-test and the alpha level was set at 0.05. Results: The waist, hips, and thighs of obese elderly women were thicker than those of normal-weight elderly women. This physical difference resulted from body fat mass, not muscle mass. Despite a similar level of limb muscle mass between the two groups, the upper limb grip strength was higher (24.00% for left, 19.95% for right) in the normal-weight women than the obese women (p<0.05), but otherwise there was no difference in maximal knee flexion or extension isometric strength. Functional physical ability showed no difference in a 30-second chair sit and stand test and a six-minute walk test, but a 30-second arm-curl (11.00% for left, 14.81% for right), back stretch (8.54cm for left, 8.99cm for right), chair sit and reach (9.22cm for left, 6.24cm for right), and 2.44 meter round trip walk (0.62 sec, 9.39%) were faster in performance for normal-weight elderly women than obese elderly women (p<0.05). Conclusion: Taken together, despite similar levels of upper and lower extremity muscle mass, normal-weight elderly women showed higher performance in upper limb strength, flexibility, and agility than obese elderly women, but there was no difference in lower extremity functional muscle strength and cardiopulmonary endurance.

Purpose: We evaluated the physical stress and pain to the musculoskeletal system of a dental practitioner when engaging in a dental scaling training exercise to prevent the development of musculoskeletal injuries. Methods: The 18 female (average age: 21$\pm$1 years) subjects were voluntarily picked from a group of juniors who have completed a one-and-a-half year training course that includes training exercises on the dentiform and on live subjects (other trainees). The test is done by measuring pain, activity, grip strength, and finger dexterity for each subject's hand and wrist. Before the test all subjects were confirmed to be right-handed and were informed of the study and its objective. Measuring was done before and after each subject performed dental scaling for one hour using the scaler and the curet. Results: Pain levels increased for both hand and shoulders, but hand pain was often greater than shoulder pain. Grip strength significantly declined in the right hand but not the left. For joint mobility, the flexion and the extension for the shoulder joint did not change; but the range of motion for both wrist joints significantly increased. For the dexterity test, both hands showed increased dexterity after the exercise. Conclusion: Dental scaling can affect the shoulders and wrists/hands. Therefore, a musculoskeletal injury prevention program for dental practitioners, which may include encouraging them to assume correct body posture when at work, must be sought. This study evaluated only the shoulders, wrists, and hands; but future studies should include areas such as the cervical area, the back, and the lower limbs.
