Supported elbow extension with wrist flexion (waterfall)
Goal
Uses body weight for graded flexor–pronator stretch with easy dosing via lean.
Motion taxonomy (reference)
Also called: dynamic finger extension stretch
Muscles — finger extensors, forearm stabilizers
Tendons — finger extensor tendons
Bones / joints — DIP joints, MCP joints, phalanges, PIP joints
Indexed benefits: helps reduce hand stiffness · improves finger opening · promotes blood flow
Common contexts: dynamic mobility · hand awakening · stiff fingers
Best for
- Forearm flexor tightness
- Post-cast gentle elongation
Default dose
6 reps • 12s hold • 2×/day
Equipment
Counter or sturdy table
Avoid when
- Acute nerve irritability with sustained elbow extension
Measurement targets
- Hold time
- Symptom threshold distance
Setup
- Stand facing a counter; place palms on the edge, fingers pointing down.
Steps
- 1Straighten the elbows gently.
- 2Let body weight bring wrists toward extension over the edge.
- 3Hold the stretch in the forearms.

- Sharp pain (≥ 4/10)
- Increasing swelling during or after
- New or worsening numbness or tingling
- Color change in fingers (pale, blue, red)
