TheraCount
A computer-vision exercise tracker built for physical therapy patients doing prescribed home exercises, counting reps, cueing form, and sending a clean progress report to their physical therapist between visits.
Adults in physical therapy doing at-home rehab after surgery, injury, or chronic pain
- Library of common PT exercises (squats, bridges, shoulder rotations, heel slides) with target rep counts from the prescription
- Real-time form feedback ('lean further forward', 'don't lock the knee', 'slower on the way down')
- Weekly progress summary the patient can text or email directly to their PT
- Quick pain and stiffness check-in before and after each session, trended over time
At-home PT has become the norm post-pandemic, and physical therapists currently have no reliable way to know whether patients are actually doing their exercises correctly between visits.

Hinge Health ($588M revenue, $3B IPO) and Sword Health ($285M Kaia acquisition, Jan 2026) already use computer vision for home exercise tracking, form feedback, and PT reporting — incumbents are consolidating this exact space.The Digital MSK Consolidation: Sword Buys Kaia, Hinge IPOs ↗Top 12 Hinge Health Competitors & Alternatives [2026] ↗Best AI Physical Therapy Software ↗
CMS RTM codes (98975, 98977) explicitly reimburse PTs for monitoring home exercise adherence, creating a real revenue path — but this B2B channel is already captured by Hinge/Sword; direct-to-patient willingness to pay for rep counting is unproven.2024 Remote Therapeutic Monitoring CPT Codes: Cheat Sheet ↗RTM Codes: How to Use Remote Therapeutic Monitoring for PT and OT ↗
Rehab needs only grow as populations age and joint replacements rise
Real-time pose estimation is feasible with MediaPipe/OpenPose, but clinical-grade form cueing, HIPAA compliance, potential FDA classification as a medical device, and EMR integration with PTs make this materially harder than consumer fitness apps.AI tools for rehabilitation exercises - BUHAVE ↗
