The Effects of Mental Practice Combined With Proprioceptive Neuromuscular Facilitation on Muscle Strength of Upper Limb and Hand Grip

Study Overview
=================
Brief Summary
-----------------
Influence of mental practice and proprioceptive neuromuscular facilitation on muscle strength of upper limb and hand grip will be measured in 30 to 50 healthy students with right dominant hand, Their age will be ranged from 18 to 26 years old. Subjects will randomly assigned to either proprioceptive neuromuscular facilitation (PNF) group or proprioceptive neuromuscular facilitation with mental practice (PNFMP) group.

Detailed Description
-----------------
PNF group: 15 - 25 individuals, these subjects will receive only PNF training. PNFMP: 15 individuals, these subjects will receive PNF training with MP. Training program will be conducted for every group for 5 weeks with 3 sessions x 30 min per week. Electromyography (EMG) device will be used to measure the electrical activity of muscles using surface electrodes. Hydraulic hand dynamometer will be used to measure hand grip strength.
