Study of Human Movement Using Assistive Devices for Limb Conditions Evaluating Prosthetic and Orthotic Device Effects on Mobility

What this Trial Is About

Researchers are investigating how individuals with limb weakness, limb paralysis, limb loss, or movement disorders move in various settings using different assistive devices and technologies. The study aims to understand how these devices impact human movement to improve technology and prepare for commercialization. Participants include both nondisabled individuals and those with disabilities who use assistive devices such as prostheses and orthoses. The study compares participants using their usual assistive devices or no device with those using investigational or commercially available devices, including prosthetic knees, ankles, feet, and ankle-foot orthoses. Activities are categorized into movement analysis in the laboratory and outside it, usability testing, and focus groups. Participants may complete different combinations of these activities, possibly more than once. During the study, participants will undergo various movement tests including walking speed, sit-to-stand timing, and the Timed Up and Go test, both with and without assistive devices. Assessments are collected at baseline and immediately after acclimating to the intervention. Participants perceptions are recorded, and safety during treadmill use is ensured. The studys involvement varies per individual and includes multiple assessments to evaluate assistive technology impact on mobility.
