 During any period of rehabilitation it is important to select meaningful tests that; measure what you want, are responsive to changes in the patients condition and, easy to use in the clinical settings. With an amputee such tests may help make sure that rehabilitation programmes and the prosthesis artificial leg provided are tailored for the individual. New prosthetic technology is continually being developed and the active amputee now demands more from their artificial limbs. Making sure that they get the right rehabilitation programmes and the most appropriate prosthesis will help them perform to their best.
