Standing Ulnar Nerve Mobilization
- Beginner
- Isolation
- Timed hold
- Back
- Shoulders
- Upper arms
This mobilization technique improves the sliding health of the ulnar nerve to alleviate tension and tingling in the forearm and outer fingers. It is highly effective for improving mobility through the cubital tunnel and Guyon's canal by gently 'flossing' the nerve through its pathway.

Setup
- Stand with a tall posture, feet hip-width apart, and shoulders relaxed.
- Extend your target arm out to the side at shoulder height with your palm facing the ceiling.
- Form an 'OK' sign by touching your thumb and index finger together, keeping the other three fingers extended.
How to do it
- Bend your elbow and rotate your wrist to bring the 'OK' sign toward your eye, as if creating a 'monocle' or 'mask' shape.
- Inhale as you bring the hand toward the face, and exhale as you return to the starting position or slightly tilt your head away to create gentle tension.
- Perform 10-15 repetitions in a slow, rhythmic 'flossing' motion, ensuring you never hold a position of high tension.
- Repeat the sequence on the opposite arm to maintain bilateral nerve health.
Form checklist
- Keep your shoulder blade depressed and avoid shrugging toward your ear.
- Move slowly and stop if you feel sharp pain, intense tingling, or lasting numbness.
- Maintain a neutral spine and avoid leaning your torso to compensate for lack of mobility.
- Focus on gentle, rhythmic tension rather than a deep, static stretch.
Pro tips
- Think of the nerve like a string; to 'glide' it, you should create tension at one end (the wrist) while releasing it at the other (the neck).
- Keep your breathing relaxed and deep to prevent the nervous system from 'guarding' or tightening up during the movement.
Make it harder
- Depress the shoulder girdle further throughout the movement to increase the baseline tension on the nerve path.
- Incorporate a simultaneous head tilt away from the active arm as the hand reaches the 'monocle' position to maximize the glide.
