Amputation Pain

The goal of this clinical trial is to see if electrical stimulation applied through the application of a wearable suit improves pain and function among adults with lower-limb amputation who report pain in two or more body regions. The main questions this study seeks to answer are: * Does the suit provide a viable treatment option for pain management? * Does the intensity of electrical stimulation matter? Researchers will compare two different intensities of electrical stimulation applied through application of a wearable suit to see the immediate, sustained and cumulative effects on pain and function among adults with lower-limb amputation. Participants will: * Fill out questionnaires online. * Undergo two onsite clinical examinations. * Complete 10 treatment sessions over 2-3 weeks.
