Lower-Limb Amputee Rehabilitation
Transfemoral suspension
A belt is worn around the individual’s waist, above the contralateral iliac crest and attaches to the lateral and anterior surfaces of the prosthesis (Murphy, 2013; Spires, Kelly & Davis, 2013)
A liner is rolled onto the individual’s residual limb with a protruding pin secured distally, which aligns with a lock in the distal end of the prosthetic socket (Murphy, 2013; Spires, Kelly & Davis, 2013). This suspension can also use a lanyard or strap instead of the pink lock (Spires, Kelly & Davis, 2013).
​
Requires the individual’s bare skin to maintain contact with the inner socket of the prosthesis, with a one-way valve to allow the release of excess air to maintain suspension (Murphy, 2013; Spires, Kelly & Davis, 2013).
A liner made of silicone is donned with a hypobaric sealing membrane (HSM) encircling the outside of the liner at the distal one-third (Murphy, 2013). A one-way expulsion valve is on the socket below the level of the HSM, and is used to expel pocketed air to secure the suction from the membrane (Murphy, 2013).
