Functional outcome of lower-limb amputees: a prospective descriptive study in a general hospital.

Abstract

This paper describes functional outcome of a population of lower limb amputees five months after amputation compared with their preoperative functional abilities and studies the relationship between potential determinants and functional outcome. Twenty out of 26 patients who underwent a lower limb amputation between December 1993 and August 1994 in a general hospital in Amsterdam were included in the study. Their functional abilities before amputation were retrospectively assessed using an ICIDH (International Classification of Impairments, Disabilities and Handicaps)-based questionnaire. Functional outcome was assessed after amputation of the lower limb using ICIDH-based and SIP (Sickness Impact Profile)-questionnaires. The mean SIP scores were high (referring to a low functional outcome). Disabilities were spread over the five disability fields of the ICIDH. The functional outcome of the diabetic versus the non-diabetic group was lower on the physical, activities of daily living (ADL), psychological and communicative categories of the ICIDH. In most patients, functional outcome decreased. The diabetic patients compared to the non-diabetics showed more diversity in functional outcome, compared with their preoperative functional abilities. Increasing age is significantly associated with a low functional outcome on the SIP scores. Diabetes is age-related for this sample. Co-morbidity and motivation are strongly age-related for this sample. It was concluded that lower-limb amputees appear quite disabled in all disability categories of the ICIDH and as assessed by the SIP scores. In most patients, functional abilities decrease after lower limb amputation. Age seems to be a significant factor related to functional outcome.
