Description
Summary:This study investigated the effect of cervical flexor muscles fatigue on neck proprioception and postural stability. Forty-five male and female subjects were evaluated pre, immediate after induction of fatigue, and after recovery. Isometric neck flexor muscle endurance test (NET) was used for the induction of cervical flexor muscle fatigue. Cervical proprioception was assessed by cervical joint position error test (JPET) via overhead laser pointer while postural stability was assessed by using (a) biodex balance system measuring "Overall stability index (OSI), Anterior/ posterior (A/P) index and medial/ lateral (M/L) index", (b) multidirectional reach test. There was a significant decrease in cervical proprioception (cervical joint position error test) and postural stability (biodex balance system & multidirectional reach test) immediate post-induction of fatigue compared with both before induction of fatigue & after recovery from fatigue (p
