The goal of this clinical trial is to learn whether a 6-week mobile-delivered intervention combining mindfulness meditation (Headspace) and personalized, wearable-derived physical activity goals (Oura Ring) can be feasibly delivered to young people who are 1-5 years post-anterior cruciate ligament reconstruction (ACLR) and who have elevated fear of reinjury. The main questions it aims to answer are: * Can the Mind in Motion intervention be implemented with acceptable rates of recruitment, retention, engagement (mindfulness session completion, Oura Ring wear), and participant-rated acceptability? * On days following a completed mindfulness session, do participants report lower anticipated fear of movement and show higher objectively measured moderate-to-vigorous physical activity (MVPA), compared with other days? Participants will: * Complete two brief in-person visits (approximately 1 week apart) that frame a 6-week home-based intervention period, followed by a remote assessment 4 weeks after the intervention ends. * Wear a research-grade activPAL accelerometer on the thigh for 7 days before and 7 days after the intervention to measure objective physical activity. * During the 6-week intervention, complete five 10-minute Headspace mindfulness sessions per week, wear an Oura Ring daily to receive personalized daily activity goals, and complete brief twice-daily check-ins (ecological momentary assessments) about fear, mood, and activity. * Complete standard questionnaires about injury-related fear, psychological readiness for activity, and knee function/symptoms at baseline, mid-intervention, immediately after the intervention, and at a 4-week follow-up. * Complete a brief audio-recorded exit interview describing their experience with the intervention. This is a single-arm, single-site feasibility study; there is no control group and no randomization. Findings will inform the design of a future multisite randomized controlled trial.
Rationale. Anterior cruciate ligament reconstruction (ACLR) is among the most common orthopaedic procedures performed in the United States, occurring most frequently in adolescents and young adults. Although surgery restores mechanical knee stability, more than 60% of patients fail to meet physical activity guidelines by 9-12 months after surgery, and patients with ACLR are markedly less likely to meet aerobic activity recommendations than uninjured peers. This shortfall is not explained by physical impairment alone: injury-related fear (fear of reinjury or of pain with movement) is one of the…
Inclusion Criteria: * 15-30 years old * Undergone primary, unilateral anterior cruciate ligament reconstruction (ACLR) * 1-5 years post-ACLR at enrollment * Elevated injury-related fear at baseline, defined as a score of 17 or greater on the Tampa Scale of Kinesiophobia-11 (TSK-11) * Self-reported reduction in physical activity since ACLR, as confirmed through the ACL-RETURN survey administered during prescreening * Medically cleared for physical activity participation * Willing and able to wear an Oura Ring daily for 6 weeks * Willing and able to complete mindfulness sessions delivered throu…
Over a 6-week home-based period, participants complete five 10-minute Headspace mindfulness sessions per week (drawn sequentially from the Basics, Sports Rehabilitation, and Sport Recovery courses) and wear an Oura Ring daily to receive a personalized daily moderate-to-vigorous physical activity (MVPA) goal, generated each day from the 60th percentile of the participant's own preceding 9 valid days of Oura-measured MVPA.
