The Effect Of Cervical Muscle Fatigue in Neck Proprioception and Postural Stability

PURPOSE: To investigate the effect of cervical muscle Fatigue on neck proprioception and postural stability during cervical flexion. BACKGROUND: Postural stability is the ability to maintain the body in equilibrium either at rest or in a steady state of motion . Muscle fatigue is the diminished response of muscle to repeated stimulus. Cervical proprioceptive inputs provide important somatosensory information influencing postural stability. Hence, the investigators performed this study to evaluate the effect of experimentally induced fatigue on general cervical musculature on postural stability . HYPOTHESES: This study will hypnotize that: 1. Cervical flexor muscle fatigue will have a significant effect on neck proprioception 2. Cervical muscle fatigue will have a significant effect on posture stability RESEARCH QUESTION: Will fatigue of cervical flexors have an effect on neck proprioception and postural stability?
