The Correlation Between Ankle Proprioception And Lower Extremity Muscle Reactions In Response To Simulated Lateral Ankle Sprains, Erin M. Carroll

Theses and Dissertations

Context: Lateral ankle sprains are one of the most commonly occurring sport-related injuries. The somatosensory system is primarily responsible for monitoring the position of the joints in space during movement. This system functions by way of neurological structures that provide proprioceptive and neuromuscular input to the brain. Motor control of the lower extremity relies on proprioceptive input to the central nervous system (CNS) and local neuromuscular control of each joint to produce coordinated, global muscular responses to external events. Previous research has investigated links between proprioception and neuromuscular control in relationship to ankle inversion separately, but none have searched for …
