Pulley Guard: Wearable Load Monitoring + Injury Risk Alerts
A thin, adhesive finger sensor (worn on the proximal interphalangeal joint) that measures real-time tendon load, grip intensity, and micro-movements during climbing. It syncs to a mobile app that tracks cumulative weekly load, compares against individual baseline capacity, and sends alerts when climbers approach their personal injury threshold—typically 3–5 days before pulley rupture occurs. The device uses strain gauges and IMU data to detect the specific loading patterns that precede pulley failure.

Value Proposition
First product to provide *predictive* warning (not reactive pain feedback) based on individualized load capacity. Climbers get 3–5 days to deload before injury, not a surprise rupture mid-session. Coaches gain objective load data to program training safely. Beats generic 'rest more' advice because it's specific to each climber's actual tissue tolerance.
Target Audience
Competitive sport climbers (ages 18–45), climbing gym members training 4+ days/week, and climbing coaches managing athlete injury risk.
Key Features
- Adhesive finger sensor (replaceable every 2–3 weeks, ~$8 cost)
- Real-time load measurement in Newtons and cumulative weekly load tracking
- Personalized injury-risk threshold calibrated via 4-week baseline period
- And more, with full implementation detail...

Rock climbers cannot reliably predict or prevent finger pulley injuries before they occurClimbers face debilitating finger pulley injuries that can sideline them for months, but lack practical methods to anticipate when an injury is imminent based on their training load and climbing intensity. Current solutions rely on generic rest advice or post-injury rehabilitation, failing to provide predictive warning signs or personalized injury prevention protocols. Athletes are forced to either push through pain and risk catastrophic injury or stop climbing entirely without knowing if they're actually at risk.
