 MS patients report difficulty implementing and continuing with home exercise, mobility, and walking programs. This feasibility study will test integration of a successful behavioral caregiving intervention into clinical practice to improve functioning of Veterans with multiple sclerosis MS and their Caregivers. Caregivers of Veterans with MS will receive a behavioral caregiver intervention designed to address caregiver coping and management of patient concerns, with special focus on patient mobility and walking. A pre-post intervention design will compare outcomes for Veterans and Caregivers.
