Generalized joint hypermobility (GJH) has been defined as a form of joint laxity that affects an individual systemically, with 5-43% of individuals in the population affected. These individuals experience injuries at a higher frequency and severity than the normal population. The purpose of this investigation was to determine if female collegiate division I lacrosse players with GJH demonstrated different muscle forces than matched controls during a demanding athletic-like task. EMG, kinematic, and kinetic data were collected as participants performed a single leg land and cut task. The GJH group demonstrated overall similar muscle forces in the lower extremity to controls. This is unexpected given the need for joint stability in the lower extremity of those individuals with greater generalized joint laxity.
