The Lie Femurett(Tm)1 adjustable training prosthesis was evaluated on 51 above-knee amputees attending the Oxford Disablement Services Centre. In the elderly it proved superior to the Pneumatic Post-Amputation Mobility Aid (P.P.A.M.-Aid) (Tm)2 in the assessment of their ability to use a prosthesis, and is useful for walking training once the stump is fully healed; it does not replace the P.P.A.M-Aid at the early post-operative stage.
