The goal of this clinical trial is to evaluate the impact of using the Nomad powered KAFO in people who have had a musculoskeletal or neurological injury that has affected their ability to walk. The main questions it aims to answer are to quantify the effectiveness of the Nomad in improving mobility, balance, frequency of falls, and quality of life in individuals with lower-extremity impairments compared to their own brace, over three months of daily home and community use.
Participants will:
* Wear a sensor that records everyday activities and mobility. * Perform measures of mobility and different activities of participation using their own brace. * Perform measures of mobility and different activities of participation using the Nomad powered KAFO
