Prosthetic sockets are secured to the residual limb by a variety of suspension techniques, including mechanical (straps, pin locking liners) and suction (sealing sleeves, one-way valves, vacuum pumps) systems. Evidence strongly suggests the benefit of vacuum-assisted suspension (VAS) over other suspension techniques, including: reducing residual limb volume fluctuations that compromise socket fit, improving gait symmetry, reducing relative motion between the residual limb and socket, facilitatin...
