Evaluating asymmetry in prosthetic gait with step-length asymmetry alone is flawed

Highlights ► Prosthetic gait asymmetry is often evaluated in terms of step-length asymmetry. ► Step-length asymmetry depends on the relative contribution of forward foot placement and trunk progression asymmetries. ► Hence, step-length asymmetry alone is not a valid marker of prosthetic gait asymmet...

Summary:Highlights ► Prosthetic gait asymmetry is often evaluated in terms of step-length asymmetry. ► Step-length asymmetry depends on the relative contribution of forward foot placement and trunk progression asymmetries. ► Hence, step-length asymmetry alone is not a valid marker of prosthetic gait asymmetry. ► Adding an assessment of foot positioning relative to the trunk is recommended.
