• Description:
  By 2050, an estimated 1.5 million people in the United States will be living with a major lower-limb amputation, a condition that causes severe disability, particularly for persons with transfemoral (above-knee) amputations. These individuals expend up to twice the metabolic effort to walk at half the speed of able-bodied persons, and they experience a higher risk of falls and secondary pathological conditions, such as osteoarthritis, back pain, and depression. Passive prostheses cannot fully replace the biomechanical function of intact legs during walking, as they are unable to provide biologically accurate torque at the joint level. Persons with amputations must compensate for this deficiency by increasing their muscular effort on both the residual limb and contralateral leg. However, these compensatory strategies result in kinetic and kinematic gait asymmetries that reduce gait efficiency and cause higher stress on the musculoskeletal system.
