Disclosed embodiments describe techniques for body part motion analysis using kinematics. Two or more sensors, which include stretch sensors or inertial sensors, are attached to a body part of an individual. The two or more sensors enable collection of motion data of the body part. Data is collected from the two or more sensors, where the two or more sensors provide electrical information based on a micro-expression of movement of the body part. One or more processors are used for analyzing the electrical information from the two or more sensors. A movement biomarker is generated for the individual, using the electrical information that was analyzed. Subsequent data is collected from a subsequent attaching of the sensors to a body part. The subsequent data is analyzed to generate a longitudinal movement biomarker for the individual. The longitudinal movement biomarker can be used for clinical evaluation or treatment planning.
