Reverse DIP blocking
Isolated DIP extension with PIP stabilized in flexion
Selective terminal extensor recruitment with PIP flexed — useful when DIP extension is lagging but central slip concerns are ruled out by the treating clinician.
Best for
- DIP extension lag
- Distal joint stiffness after immobilization (cleared)
Default dose
8 reps • 2×/day
Setup
- Stabilize the middle phalanx with the other hand so the PIP stays gently bent.
Steps
- 1Keeping the middle joint bent, straighten only the tip joint.
- 2Lower the tip slowly.
Cues
- Small range; quality over force.
- The middle joint should not straighten during the move.
Common mistakes
- Straightening the whole finger together.
- Pushing into sharp pain at the tip.
Stop rules
- Sharp pain (≥ 4/10)
- Increasing swelling during or after
- New or worsening numbness or tingling
- Color change in fingers (pale, blue, red)
- Wound opens, drains, or feels hot
- Next morning is worse than the day before
- Joint clicks or new instability
Progressions
- Add a brief 2–3 sec hold at end range when comfortable.
Regressions
- Smaller range; fewer reps; longer rests between reps.
What to do next — not a dead end
Suggestions use body region, goal, motion type, and allowed phases — not your medical record. After surgery or a flare, follow your clinician first.

Phases 2, 3
Higher load or coordination — scale range and speed.
Avoid if this sounds like you
Mallet finger / acute extensor tendon injury at the DIP without clearance
Boutonniere pattern or central slip concern
