This is a feasibility study about implementing and using the KinetiGait gait analysis system in clinical practice to enhance the rehabilitation of service members with lower limb disfunction. There will be questionnaires completed by participants and surveys completed by both participant and provider.

We propose a feasibility study about implementing and using the KinetiGait gait analysis system in clinical practice to enhance the rehabilitation of service members with lower limb dysfunction. Up to 100 subjects will be consented, with the expectation that 80% (e.g., n=80) will complete the study with a complete dataset. Baseline sessions will consist of 7 minutes of walking at a self-selected speed between 0.7 and 1.3 m/s, after which participants will take the PLUS-M 12 Item Short Form and PROMIS-29 questionnaires, as well as a short survey. Participants will complete the questionnaires again at 1 month and 3 month. Providers who observed/operated the KinetiGait system will also take a short survey on ease of use and satisfaction.
