Mixed Reality Based System to Manage Phantom Pain Phantom Pain for Patients With Lower Limb Amputation

The primary goals of this pilot research project are a) to design and develop the a mixed reality based system for managing phantom pain and b) to evaluate the feasibility and preliminary functional outcomes of this system in a sample of patients with lower limb amputation. Findings from this pilot study will serve as preliminary data to inform regarding a fully powered clinical trial to determine the effectiveness and practical implementation of these findings in real-world settings. Aim1: Design and develop a feasible mixed reality based system to manage phantom pain in patients with lower limb amputation qualifying for on-going mirror therapy. Hypothesis 1: The investigators hypothesize that the mixed reality based system to manage phantom pain will be feasible and well-received by a sample of patients with lower limb amputation needing mirror therapy. Aim2: Evaluate functional outcomes in a sample of lower limb amputees (n=10), using this mixed reality based system to manage phantom pain. Hypothesis 2: Using this system, the investigators hypothesize that patients who participate in the mixed reality based system will show improvements in functional mobility based on performance evaluations and patient reported outcome measures (PROs). The investigators also hypothesize that this mixed reality based system will help to alleviate the phantom pain based on McGill Pain questionnaire and visual analog scale (VAS).
