To do this, the investigators will evaluate the performance of commercially available inertial measurement unit sensors incorporated into an existing ankle brace (\"sXAB\") by TayCo Brace, Inc. We will compare the gait metrics calculated from the sensors incorporated into the brace with gold-standard equipment that is used in research and clinical settings to determine whether the sXAB performs adequately in terms of measurement or technical feasibility prior to further clinical evaluation. The sensors in the ankle brace will be validated in the lab, first on healthy subjects walking in standard tennis shoes\u002Fsneakers (protocol 1), and secondarily in the lab on healthy subjects wearing combat boots performing walking, running, jumping, and stair climbing (protocol 2). These movements were selected because they simulate key movements performed during operational activities. Protocol 1 will take place first, then aspects of the sXAB will be evaluated and implemented, then protocol 2 will take place. Participants completing protocol 1 are eligible to complete protocol 2. The study includes two cohorts of participants completing different functional tasks. All participants experience both conditions: with an ankle brace and without an ankle brace. Comparisons are made within-subject between brace and no-brace conditions. It is hypothesized that the sensor-enabled ankle brace will measure gait metrics with a high degree of accuracy (within 5%) when compared against the gold-standard lab equipment (i.e., motion capture and research-grade inertial measurement units).",[82,83,84,85,86],"Gait","Balance","Biomechanical Data","Postural Control","Locomotion",[88,89,90,91,92,93,94,95,96,97,98,99,100,101,102,103,104],"adult","gait","gait analysis","humans","ankle brace","motion capture","sensor validation","wearable electronic devices","wearable sensors","inertial measurement unit","IMU","locomotion","running","walking","landing","stair ascent","stair descent","2025-10-21",{"date":107,"type":108},"2025-10-23","ACTUAL",{"date":110,"type":108},"2025-10-16",{"date":112,"type":76},"2026-06-18",{"name":5,"class":6},1]
