Daily functioning of the lower extremity amputee: an overview of the literature.

The aim of this paper is to review the existing literature on the incidence, morbidity and mortality of lower limb amputation. The functional level of the lower limb amputee and the predictive factors for functioning with a prosthesis are reviewed, both for unilateral and for bilateral amputees. The reported incidence of lower extremity amputation (LEA) varies considerably between different Western countries. The mean survival of LEA patients ranges between two and five years. Assessment of functional outcome is carried out differently. Studies are not comparable and most concern selected groups of amputees. Increasing age, concurrent disease and poor compliance are prognostic factors for a low functional level. For optimal planning of rehabilitation it is necessary to study a complete cohort of amputees with respect to these prognostic factors.
