Association of quality of life with body mass index in patients using trans femoral prosthesis after amputation

Abstract

Background: Trans-femoral amputation (TFA) is an undesirable transaction of lower limb at the femoral level necessitating the use of a prosthetic device essentially requiring prolonged rehabilitation to ensure ambulation of the patient and integration into daily routine

Objectives: The objective of the study was to find the association of quality of life with body mass index in patients using trans femoral prosthesis after amputation

Methodology: Current Cross-Sectional study using convenience sampling recruited N=400 trans-femoral prosthesis users from PIPOS. Sample included both genders with age range of 12-60 years, using prosthesis > 1 year while orthosis users were excluded. SF-36 Health Survey tool & Lower Extremity Functional Scale (LEFS) were utilized for collection of data & analyzed utilizing SPSS Version 21.

Results: LEFS items revealed association (p<0.05) with BMI including get in & out of bath, walk from rooms to room, squatting, heavy activities, sit for 1 hour & hopping. There was association (p<0.05) between BMI and SF-36 items of emotional wellbeing, social function and pain.  General Health of the participants revealed association (p=0.000) with highest total LEFS score for those with good and very good health. While as regards individual items most items revealed (p<0.05) association with LEFS. General Health also revealed association (p<0.05) with all subsclaes of SF-36 with higher scores for those having very good health except domain of limitation because of emotional & social health. Etiology of amputation also revealed association (p<.001) with total mean LEFS score with highest score when etiology was fracture. Etiology also had association (p<0.05) with most items of LEFS & SF-36.

Conclusion: BMI, General Health and Etiology have significant association with status of ambulation and social performance of Trans-femoral amputees using prosthetic devices.
