A protocol for obtaining upper and lower extremity joints' range of motion in children using three-dimensional motion analysis system.

Three-dimensional (3D) motion analysis (MA) techniques are progressively being used in biomechanics research and for clinical applications to assess the risk of injuries. A marker-based 3D MA protocol has been developed to measure the upper and lower extremity (UE and LE) joints' active and passive ranges of motion (AROM and PROM) in children. The joints that were included in this protocol are shoulder, elbow, wrist, hip, knee and ankle.
