简要总结
Purpose of the study:
- To investigate the effect of rotator cuff training on hand grip strength in adults with different body mass index.
- To investigate the effect of rotator cuff training on hand grip static endurance in adults with different body mass index.
- To investigate the effect of rotator cuff training on hand grip dynamic endurance in adults with different body mass index.
- To investigate the effect of rotator cuff training on upper limb function in adults with different body mass index.
详细描述
Rotator cuff muscles are considered to be the key dynamic muscles in shoulder stabilization since they contribute significantly to shoulder stability in a number of different ways. They work not only as a dynamic stabilizer but also as static stabilizers because of their orientation and location around the shoulder joint. Several studies revealed the strong relationship between the rotator cuff muscles and hand grip strength. Studies proved the strong correlation between grip strength and rotator cuff strength ,which suggests that assessment of grip strength could be used to monitor the function of the rotator cuff, once baseline readings have been attained during training and rehabilitation .
Previous publications revealed significant positive associations between handgrip strength, body mass index (BMI) and physical activity in adult men and women. Worldwide, 31.1% of adults are reported to be physically inactive. Some studies and reports indicate that 20% of the global populace within the age range of 18-64 years comply with the minimum physical activity guidelines for improved health. Overweight and obesity are identified as a constant negative influence on physical activity, regardless of age.
Studies proved that weight, height, and BMI have a significant correlation on hand grip strength. As the weight increase hand muscle strength and endurance time also decrease.
Subjects in this study will be recruited from the students , employees and faculty members of the faculty of physical therapy, Cairo University.

结局指标
主要结局
Hand grip strength
时间窗: up to six weeks
The JAMAR Hydraulic hand dynamometer is used to measure hand grip strength in (Kg) , It will be evaluated before and after training for each subject in both groups. Each subjects will be asked to grasp the handle with the dominant hand and perform hand grip with maximum effort only during exhalation and after a verbal cue given by the examiner " one, two, three, go". The subjects will be instructed to maintain maximum contraction for 5 seconds. Three measurements will be taken with a rest interval of 60 seconds between trials in order to avoid muscle fatigue during the assessment and the average of the three measurements will be calculated to measure hand grip strength.
次要结局
- Upper limb function(up to six weeks)
- Hand grip static endurance(up to six weeks)
- Hand grip dynamic endurance(up to six weeks)
