Normative values of orthotic and prosthetic users' survey in lower limb prosthetic users across multiple follow-ups: A secondary analysis.

BACKGROUND

The Orthotics and Prosthetics Users' Survey is a validated tool designed to assess patient satisfaction, functional ability, and overall experience with orthotic and prosthetic devices. By providing normative values, it enables healthcare providers to compare individual scores against population averages.

Objective

This study establishes normative values and explores longitudinal changes in lower extremity functional status (LEFS) and health-related quality of life (HRQoL) among lower limb prosthetic users.Study

Design

A secondary analysis was conducted on data collected over four years from 186 participants who completed at least three out of five surveys during a 12-month follow up period.

METHODS

Data were gathered from 13 prosthetic clinics across the United States. To evaluate longitudinal changes in LEFS and HRQoL, separate generalized linear mixed models were applied, adjusting for age, gender, diabetes, presence of comorbidities, etiology, use of assistive devices, level of amputation, patient type, and employment.

RESULTS

LEFS scores remained stable over time. HRQoL had time interactions with patient type and level of amputation. Employment had a positive influence on both outcomes.

CONCLUSIONS

Rehabilitation strategies for lower limb prosthetic users should emphasize targeted, individualized approaches that address health-related barriers, aim to promote independence from assistive devices, and enhance social and occupational engagement.
