There are an estimated 65 million people that live with limb amputations globally, with 1.5 million people undergoing amputations—mostly of the lower limb—each year. Most people with amputations need access to prosthetic services, and this need is expected to double by 2050. [1] With a limited number of physicians with sufficient expertise in prosthetic prescription and amputee rehabilitation, there is a growing need for well-coordinated teams to guide optimal prescription and rehabilitation.

Although walking poses little challenge to individuals who are healthy, those with gait pathologies or lower-limb amputations can find it tiring and difficult [4]. Gait analysis is a well-established tool for the quantitative assessment of gait disturbances providing functional diagnosis, assessment for treatment planning, and monitoring of disease progress [1].
