Assessing Ambulatory and Non-ambulatory Community Mobility in People With Lower Limb Amputation

Summary

Mobility is a fundamental aspect of daily life, enabling individuals to participate in social, occupational, and recreational activities. Community mobility, defined as movement in environments outside the home, is particularly important for quality-of-life. Following lower limb amputation (LLA), mobility limitations are common and persistent. With rehabilitation and prosthetic training, many regain the ability to ambulate but results vary as only 25 - 58% of patients regain ambulatory ability and less than half of those who become ambulatory achieve sufficient ability to walk in community settings. As a result, \~40% of people with LLA are ambulatory but also use wheeled mobility (e.g., wheelchair, scooter) for some or all of their community mobility tasks. To date, the complementary role of wheeled and ambulatory mobility in maximizing community mobility has been overlooked, with clinical research overwhelmingly focused on assessing and improving ambulatory ability despite its impracticality for many community settings.

Detailed Description

Poor understanding of the multiple mobility modes used by people with lower limb amputation (LLA) is a likely contributor high rates of self-reported disability, poor social engagement, and lower quality of life. Understanding mobility patterns in this population is essential for developing targeted interventions, optimizing assistive technologies, and improving overall community mobility. This study addresses three limitations in rigor of prior research on community mobility in people with LLA: 1) minimal use of objectively-monitored community mobility, 2) unknown contexts of ambulatory and wheeled mobility behaviors, 3) unclear relationship between patient and clinical factors influencing mode of community mobility.
