Background: Poor adherence to home exercise programs is a persistent challenge in physical rehabilitation and beyond. Data suggest that follow-up telehealth visits featuring behavior change techniques can improve adherence. However, the optimal frequency of behavioral support for effective self-management of technology-enabled home exercise programs remains unclear. This paper investigates how adherence to home exercise varies with the number of follow-up visits holding the type of exercise constant and measuring adherence objectively. Methods: A secondary analysis of adherence was conducted on participants from the VIGOROUS five-site, single-blind, and randomized controlled trial. Chronic (>6 months) community-resident stroke survivors with mild-to-moderate upper extremity hemiparesis (n = 111) were assigned 15 h of asynchronous video game-based home exercise over 3 weeks. Participants received behavioral support during (a) one single in-person session, (b) four in-person sessions, or (c) four in-person sessions plus six remote teleconsultations. Each consultation incorporated standardized behavior change techniques—contracting, feedback, self-monitoring, action planning, and guided problem solving—to promote increased paretic arm use during daily activities. The primary outcome was adherence (minutes exercising), objectively captured by the gaming system for 87 participants. Results: Six telehealth visits with remote therapeutic monitoring (RTM) increased home exercise completion by 3.3 h 95% CI: 0.008, 6.60; each remote or in-person consultation was associated with an estimated 34 min of additional asynchronous home exercise. Conclusions: RTM, which does not require travel to a healthcare facility, is a time-efficient modality to enhance therapeutic engagement. Behaviorally focused telehealth visits boost stroke survivors’ adherence to a structured home exercise program.
