Feasibility and Preliminary Efficacy of Virtual Rehabilitation for Middle and Older Aged Veterans With Mobility Limitations: A Pilot Study

Abstract

ObjectiveTo evaluate the feasibility and preliminary efficacy of the transition of an outpatient center-based rehabilitation program for middle and older aged Veterans with mobility limitations to a tele-health platform. DesignNon-randomized non-controlled pilot study including 10 treatment sessions over 8 weeks and assessments at baseline, 8, 16, and 24 weeks. SettingVA Boston Healthcare System ambulatory care between August 2020 and March 2021. ParticipantsVeterans aged 50 years and older (n=178) were contacted via letter to participate, and 21 enrolled in the study. InterventionParticipants had virtual intervention sessions with a physical therapist who addressed impairments linked to mobility decline and a coaching program promoting exercise adherence. Main Outcome MeasuresAmbulatory Measure for Post-Acute Care (AM-PAC), Phone-FITT, and Self-Efficacy for Exercise (SEE) scale. ResultsCompleters (n=14, mean age 74.9 years, 86% men) averaged 9.8 out of 10 visits. Changes in the Ambulatory Measure for Post-Acute Care (AM-PAC) exceeded clinically meaningful change after 8 and 24 weeks of treatment, at 4.1 units and 4.3 units respectively. Statistically significant improvements from baseline in AM-PAC and Phone-FITT were observed after 8 weeks of treatment and at 24 weeks. No significant changes were observed in exercise self-efficacy. ConclusionsIn this group of veterans, telerehab was feasible and demonstrated preliminary efficacy in both mobility and physical activity, thus justifying further investigation in a larger scale clinical trial.
