Biomechanics is a science that focuses on the movement of the body. It represents the broad interplay between biology and mechanics and includes the study of how the various bones and joints of the musculoskeletal system such as the spine, hips, knees, and feet work together to help you move. A biomechanical evaluation will help detect and prevent abnormalities in joint alignment or deformities of the musculoskeletal system and guide the selection of the right biomechanical device or treatment to meet the individual needs of each patient.
