Kinematic Analysis

Definition

Kinematic analysis is the study of motion without considering the forces that cause it, focusing instead on parameters such as velocity, acceleration, and displacement. In the realm of biomedical measurements, kinematic analysis plays a vital role in understanding human movement and biomechanics, helping to inform device design and rehabilitation strategies. This approach can provide insights into how body segments move relative to one another, which is crucial for improving health outcomes and enhancing performance in various medical applications.
