The Effect of BMI on Hand Grip Force in Healthy Adults

Study Overview
=================
Brief Summary
-----------------
This study will be conducted to investigate the effect of BMI on hand grip force in healthy subjects. The participants in this study will be 90 healthy subjects with right dominant lower limb (49 females and 49 males) they will be recruited from College of Applied Medical Sciences, Jazan University.

Detailed Description
-----------------
Subjects will be categorized according to BMI into three groups: Group I (normal subjects): 30 individuals (15 male, and 15 female students) with (BMI<25 kg/m2) Group II (overweight subjects): 30 individuals (15 male, and 15 female students) with (BMI, 25-30 kg/m2). Group III (obese subjects): 30 individuals (15 male, and 15 female students) (BMI>30 kg/m2). Baseline hydraulic hand dynamometer: (Fabrication Enterprises Incorporated, White Plains,New York, USA) will be used to measure the hand grip strength and pinch strength

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Group I (normal subjects)<br>30 individuals (15 male, and 15 female students) with (BMI<25 kg/m2). Hand grip force will measured using Baseline Hydraulic Hand Dynamometer. | Diagnostic Test: Hand Grip Force<br>* For measuring the grip strength, the subjects will be asked to sit on a chair with their hip joint flexed at 90 degree, and shoulder joint in a neutral position. The elbow is fixed at 90 degree flexion, forearm in a neutral position, and wrist at 0 to 15 degree radial deviation. The test will be performed twice, and the higher value between the two measurements will be selected. The subjects will be allowed a rest time of more than 5 minutes after the first measurement to avoid examiner bias and to decrease physical stress<br>|
| Group II (overweight subjects)<br>30 individuals (15 male, and 15 female students) with (BMI, 25-30 kg/m2). Hand grip force will measured using Baseline Hydraulic Hand Dynamometer. | Diagnostic Test: Hand Grip Force<br>* For measuring the grip strength, the subjects will be asked to sit on a chair with their hip joint flexed at 90 degree, and shoulder joint in a neutral position.
