Stabilityversus Range of Motion

Articulation,which is also known as a joint, is a connection of two bones (simplejoint) or a connection of three or more bones (referred to as acompound joint). The soft tissue connects the two or more bones anddetermines the structural categorization of the joint (Rizzo, 2016).By consideration and definition of the physiology of the bones,joints are mobile. The main purpose of the joints is to enablemovement. The skeletal muscles create movement at the joints wherethey cross while the joint capsules and the ligaments limit thesemovements (Rizzo, 2016). Each and every joint in themuscular-skeletal system maintains a complementary relationshipbetween stability and mobility.

TheInterconnection between the Stability of the Joint and the Range ofMotion

Therange of motion and the stability of the joint are antagonisticabstractions that co-occur around one another (Rizzo, 2016). Theydescribe the mutual relationship between each concept based on thespecific characteristics and principles of the articulation. “Thegreater the mobility, the less stable the joint and the greater thestability, reduced is the mobility of that joint” (Rizzo, 2016)Increased stability minimizes the risk of injury while reducedstability enhances the risk of injury.

Determinantsof the Joint Stability and the Range of Motion

Thereare three primary determinants of joint stability and mobility. Theyinclude the ligaments, the shape of the bones involved in thatparticular joint, and the musculature (Rizzo, 2016). Examination ofthe joint of interest can be based on the above three factors. Jointsoffer varying degrees of stability and mobility based on the abovefactors (Rizzo, 2016). Based on the above three determinants, acorrelation of the risk and frequency of injury and mobility can bemade (Rizzo, 2016). Joints that have excellent stability tend to havedecreased risk and incidence of injuries related to mobility.


Jointsare vital in enabling movement. There exists a reciprocalrelationship between joint stability and mobility. Three main factorsinfluence the relationship between joint stability and mobility. Forefficient movements to occur, the joints need much control throughoutall movements to prevent injury through the minimization of therisks.
