Biomechanics

Definition

Biomechanics is the study of the mechanical laws relating to the movement or structure of living organisms. It combines principles from mechanics, biology, and physiology to analyze the forces and motions involved in human movement. Understanding biomechanics is essential for designing effective prosthetics that mimic natural limb functions and improve mobility for individuals with limb loss.
