Effects of walking speed on knee joint loading estimated via musculoskeletal modeling
MetadataShow full item record
Walking is the most common form of physical activity and is assumed to incur a relatively small risk of musculoskeletal injury. However, walking related- musculoskeletal injuries, particularly at the knee joint, are not uncommon in individuals who walk for exercise. Surprisingly, there is scant data regarding how walking conditions (e.g. speed, grade, surface) affect loads (i.e. contact forces) across lower extremity joints. Studies to date have used proxy measures of joint loading, primarily net muscle moments (NMM); however the validity of these proxy measures to estimate joint contact forces ...
