What is finger pulley injuries?
The finger pulleys are small ligament bands that hold your flexor tendons close to the bone — without them, your tendons would 'bowstring' away from the finger when you crimp. The A2 pulley (at the base of the finger) and A4 pulley (in the middle) take the most load from crimping and pocket holds in climbing. A pulley injury is a strain or tear of one of these ligaments, ranging from a mild sprain (Grade I) to a full rupture (Grade III–IV). Climbers most often injure the A2 pulley on the ring or middle finger, usually during a sudden load — a tweaky crimp, a small pocket, or a foot slip on a dynamic move.
Common symptoms
- A 'pop' or sudden tweak felt in the finger during a hard move
- Pain at the base of the finger when crimping
- Swelling along the front of the finger
- Bowstringing — a visible tendon lifting off the bone in severe cases
- Difficulty fully closing the finger or making a fist
- Tenderness when pressing on the base of the affected finger
- Pain that's worse on full-crimp than on open-hand grips
What causes finger pulley injuries?
Pulley injuries happen when the load on the flexor tendon exceeds what the pulley can handle. In climbing, that almost always means a crimp grip — especially full crimp — under sudden or maximal load. Foot slips, surprise dynamic moves, and over-crimping small holds are the most common triggers. Most climbers don't injure a healthy pulley out of nowhere; usually there's underlying tendinopathy or fatigue from heavy crimping volume that weakens the structure first. Training too hard with insufficient rest, ramping volume too fast, and skipping antagonist and forearm conditioning all increase your risk.
How online PT helps with finger pulley injuries
Evaluation. Your first visit is a video evaluation. Your PT asks how the injury happened, has you flex and extend the finger through different grip positions, and checks for tenderness, swelling, and bowstringing. They'll grade the injury severity and flag anything that would warrant imaging or an in-person consult.
Treatment. Pulley rehab is built on progressive loading. Early on you may need to back off crimping and lay back on open-hand grips, fingertip-only board work, or sub-max hangboard hangs in a half-crimp. As pain settles, your PT progresses you through ramped finger loading — often with isometrics, eccentrics, and grip-specific drills — until the pulley tolerates full-crimp load again. You'll also work antagonist and forearm health to prevent re-injury.
Ongoing support. Pulley injuries are easy to re-aggravate if you ramp back too fast. Between visits you can message your PT to check whether a specific hold or session is safe to try. They'll adjust your plan as you progress and give you the green light for crimping, projecting, and outdoor seasons in a measured way.
What to expect
First visit is about 60 minutes over video. By the end you'll know your injury grade (Grade I, II, or III), what to back off, and what you can safely climb on. Follow-ups are 30–45 minutes. Most Grade I and II pulley injuries recover meaningfully within 4–8 weeks of structured rehab; Grade III ruptures can take 3–6 months. Your PT builds a return-to-climbing protocol that ramps load progressively — typically open-hand to half-crimp to full-crimp under controlled grades — rather than resting six weeks and hoping it's better.
