This study examined how existing theoretical models can be used to assist in collecting fall history in people with lower limb amputation. And how these frameworks can be used to exhibit how variables related to amputation interact to affect prosthetic mobility and functioning.

This presentation will evaluate the amount of clinical service and time required to provide a lower limb prosthesis to a patient, before and after delivery. Differences in appointment frequency between sex, age, and amputation level will also be examined.

Early mobility, functional independence, and ambulation are associated with reduced healthcare utilization and economic burden, while an increased risk of clinical complications is associated with no prosthesis. Adults age 18-64 with commercial insurance, continuously enrolled with lower limb amputation were included in final analysis. The adjusted association between prosthesis receipt and the independent variables was quantified through multivariate analysis using Cox proportional hazards model regression. The results were reported using median time to prosthesis receipt and hazard ratios. It was found that those with diabetes or vascular disease were 22% more likely to receive a prosthesis earlier potentially suggesting that there are underlying differences beyond diabetes or vascular disease. The median time to receipt of prosthesis was 137 days. Among this sample of working age adults with commercial insurance, it appears that within 5 months or less at least half of the population receives a prosthesis while controlling for covariates, however disparities in timing and access to a prosthesis based on amputation level and sex should be addressed.

This paper will present the findings of an online survey of 57 patients with transtibial amputation on the effects a powered ankle-foot component on sound knee, amputated side knee, and low-back pain as well as pain-related restrictions in ADLs and disability compared to passive prosthetic feet. This is the first study to have investigated the direct impact of a prosthetic component on musculoskeletal pain that confirms earlier biomechanical findings on sound limb and spinal unloading by increased prosthetic push-off.
