Abstract
A common clinical obstacle encountered after knee joint injury is an inability to achieve full voluntary activation of the quadriceps muscle group. This phenomenon has been termed arthrogenic muscle inhibition and is defined as an ongoing reflex inhibition of musculature surrounding a joint after distension or damage to the structures of that joint. Arthrogenic muscle inhibition is a limiting factor in joint rehabilitation, as it restricts full muscle activation and therefore prevents restoration of strength. Thus, athletes often return to competition deficient in strength and neuromuscular control, leading to an increased propensity for further injury.
