Mental Practice Versus Proprioceptive Neuromuscular Facilitation on Strength of Upper Limb

Study Overview
=================
Brief Summary
-----------------
The effects of mental practice combined with proprioceptive neuromuscular facilitation on muscle strength of upper limb were measured in 60 healthy students Subjects were randomly assigned to either proprioceptive neuromuscular facilitation (PNF) group or mental practice (MP) group. PNF group: 30 individuals, these subjects received only PNF training. MP: 30 individuals, these subjects received mental practice.

Detailed Description
-----------------
The effects of mental practice on muscle strength of upper limb were measured in 60 healthy female students with right dominant hand,. Their age ranged from17 to 23 years old. Subjects were randomly assigned to either proprioceptive neuromuscular facilitation (PNF) group or mental practice (MP) group. PNF group: 30 individuals, these subjects received only PNF training. MP: 30 individuals, these subjects received MP. training program has been administered for every group for 12 sessions over 4 weeks with 3 x 45 min training sessions per week. Pre-post test design was used. EMG device was used to measure the electrical activity of muscles. Measurements conducted at pre-intervention, during intervention and post-intervention testing with 20 days.
