The functional capacity among individuals with a lower limb amputation varies greatly. The same is true for the evolution of an individual's capacity over time. Such capacity is influenced by many factors such as age, cause of amputation and related diseases. Currently, evaluations used to assess and monitor individuals with an amputation usually focus on their general ability to perform a task and not on how movement is specifically coordinated or on the potential impact of secondary physical complications. A detailed analysis of key activities of daily living will better quantify the evolution of the functional capacity of individuals with a lower limb amputation.

The long-term goal of this research program is to improve the understanding of clinical and movement factors that influence the evolution of functional capacity and the occurrence of secondary physical complications in individuals with a lower limb amputation.

A study will be first conducted on a group of individuals with an amputation compared to a healthy group. This study will identify movement elements and strategies distinguishing an individual with an amputation from a non-amputee during key tasks, and also identify the most relevant clinical factors to consider. The interaction between these factors will also be analyzed. Subsequently, a long term study will be conducted with 60 individuals having a lower limb amputation. Individuals will be evaluated at short, mid and long term following the beginning of wearing prosthesis. The same analyses of movement and clinical tests will be conducted at specific points and across the long term.  

This program will help to better identify the movement and clinical factors relevant for clinical follow-up of an individual with a lower limb amputation. These factors will be used to better detect secondary physical complications and to improve the monitoring of this population.
