In Brief:
Biomechanics can be used to assess the quality of joint range of motion, proprioception, postural balance control, and muscular function, which are all critical components that contribute to improved mobility. This article aims to provide an overview of the fundamental biomechanical approaches to collecting and analyzing data, as well as offering examples of how to conduct biomechanical evaluations and analyses to improve mobility in health and fitness settings using minimal equipment and simple administration.
