Current Concepts in Upper-Extremity Motion Analysis: Room To Grow?

Kinematic motion analysis (KMA) is well established in the assessment of gait and lower-extremity kinematics; however, its application to upper-extremity (UE) pathology has been limited. This review provides a concise overview of information related to the KMA technology that is pertinent to the clinician. Advantages of KMA for UE assessment are discussed, along with barriers to implementation. An example of KMA used for perioperative assessment of a patient undergoing a distal humerus osteotomy for the correction of arthrogrypotic internal rotation deformity is provided to illustrate its clinical feasibility. Kinematic motion analysis has exciting potential to advance the evaluation and management of UE disorders; however, broad application will require validation and standardization of UE-specific KMA protocols in addition to decreased logistical and cost burdens.
