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.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Group A | Experimental | Group A receives the intervention Nomad KAFO first; fitting & training will occur with the intervention and will then be used for a 3 month home trial, followed by outcomes testing. Group A then will cross over and train with their own Traditional Assistive Device and will then use their own device for a 3 month home trial, followed by outcomes testing. |
|
| Group B | Active Comparator | Group B receives training in their own Traditional Assistive Device first; training will occur with their own Traditional Assistive Device and will then use their own device for a 3 month home trial, followed by outcomes testing. Group B then will cross over and receive the intervention Nomad KAFO; fitting & training will occur with the intervention and will then be used for a 3 month home trial, followed by outcomes testing. |

| Indego Nomad® Powered Knee-Ankle-Foot Orthosis (P-KAFO) (Parker Hannifin Corp., Cleveland, OH) | Device | The Nomad is a microprocessor-controlled knee-ankle-foot orthosis P-KAFO that incorporates a motor for powered movement assistance and an electronic brake for stance support. The system provides active assistance for knee flexion and extension during the swing phase of gait, reliable stance phase locking at any knee angle, and reliable unlocking without requiring user-generated knee or hip extension torque. |
