The Effect of Prosthetic Leg Length on Low Back Muscle Activity and Pain during Walking and Sit-to-Stand
People with lower limb amputation have a greater incidence of low back pain than the general population, with some estimates as high as 65%. One potential cause of pain in this population is leg length asymmetry as it can lead to altered trunk-pelvis movement, and subsequently altered low-back loading. The purpose of this study was to determine the effect of changes in prosthetic leg length on low back muscle activity and self-reported low-back pain.
