Brief Summary

Summary Muscle fatigue is a serious problem commonly occur in older ages. Muscle fatigue disturbs both daily life activities and rehabilitation tolerance in elderlies. Muscle fatigue happens due to the motor or sensory dysfunctions. The previous interventions focused mainly on the motor causes of muscle fatigue, however the important role of the sensory system in driving the motor system. It has been demonstrated that proprioceptors are mainly responsible for sensing the muscle fatigue. Objectives: This study will be conducted to investigate 1. The effect of proprioception training on reducing the occurrence of muscle fatigue in elderlies. 2. The effect of proprioceptive training on delaying the deterioration in electromyographical data from muscles of lower limbs.

Control group

PLACEBO COMPARATOR

The control group will receive an isokinetic strengthening program for the quadriceps muscles. Twenty-four strengthening session will be performed using an isokinetic device. The exercise program begins with 60% of the mean peak torque, and the patient reaches this intensity by auditory biofeedback. An increasing dose program will be used in the first 5 sessions (1 set to 5 sets), and a dose of 6 sets will be applied from the sixth to twenty-fourth sessions, with the density rising from 60% to 80% of the mean peak torque according to the patient tolerance. Each set consisted of 5 repetitions of concentric (Con/Ecc) contraction in angular velocities of 30°/second and 120°/second for extensors. This program accomplished significant results in increasing quadriceps power and strength.

Device: Isokinetic dynamometer

Study group

EXPERIMENTAL

* Participants in the study group will perform the same exercise parameters used in the control group but in a different manner. * The isokinetic exercise will be done with a closed eye to improve the proprioception function. This exercise will be performed for 6 sets. * Additional training will be performed by the application of three vibrators above and on both sides of the knee joint to improve the function of the Pacinian and Meissner corpuscles which is one of the included receptors in the sensation of the fatigue.
