Goralign PSA is a self-adaptive prosthetic ankle component. It is integrated with and in between a prosthetic foot and a pylon or socket.Goralign PSA 2, where “PSA” stands for “Plus Shock Absorber”, is the next generation of Impulse Technology's prosthetic ankle that self-adapts to uneven terrain and enhances patient comfort and motion through its nonlinear stiffness featuring self-adaptation throughout all phases of gait. The self-adaptive feature helps mitigate gait changes due to terrain and misalignment over time by self-aligning.
A mechanical device which is a component of an external lower limb prosthesis designed to functionally replace, in part or total, an absent foot and/or ankle, wherein the principle of operation for dorsiflexion/plantar flexion control is based on media-free mechanical resistance (i.e., mechanical friction/elastic deflection with no fluid or gas operating media). The device may have various designs and functional features (e.g., SACH, SAFE, partial-foot, energy-storing carbon fibre spring blade type, adjustable heel height, split/sandal toe) for support during a variety of activities.
