This pilot study will evaluate the feasibility and preliminary effectiveness of incorporating Extended Reality (XR) into the treatment of patients undergoing Lower Limb Rehabilitation (LLR) using the Vector Gait and Safety System. LLR requires repetitive motions over the span of weeks or months with the aim of restoring mobility. This duration of time poses challenges with motivation and increases the burden on the physical therapists. The use of XR in conjunction with conventional physical therapy could significantly increase motivation, along with providing therapists with new ways of tracking the patient's recovery. Pilot study results will be used to propose new and innovative approaches to physical recovery during inpatient rehabilitation, potentially increasing motivation, enhancing therapy participation, and reducing the overall time taken for recovery.
