Median Nerve Glide

Also called: Nerve flossing

Nerves are not fixed cables. They slide and lengthen a few millimetres every time you move, and when a nerve cannot glide freely through a narrow space, such as the median nerve at the wrist, movement starts tugging on it instead of moving it. A nerve glide restores that sliding gently: you take up slack at one end while releasing it at the other, so the nerve travels without ever being stretched. These are worth doing, and they are a supporting act. For carpal tunnel symptoms the first line treatment is a night splint holding the wrist neutral while you sleep, since that is where most of the night waking comes from, and glides work alongside it rather than instead of it.

Median Nerve Glide

Demonstration photo coming soon

At a glance

A sequence of hand and arm positions that helps the median nerve slide freely rather than becoming tethered. A useful adjunct alongside a night splint, not a replacement for one.

What it works

Primary muscles

  • None: this is nerve mobilisation rather than muscle work

Also involved

  • Forearm flexors, lengthened gently as the wrist extends
  • Wrist and finger extensors, working lightly to hold each position

Equipment: None

How to do it

  1. 1

    Sit or stand tall with the affected arm at your side, elbow bent to ninety degrees, palm facing up, fingers and thumb loosely curled into a fist.

  2. 2

    Open the hand: straighten the fingers and thumb with the wrist neutral and the palm still facing up.

  3. 3

    Bend the wrist back so the palm turns away from you and the fingers point down towards the floor, keeping the elbow bent.

  4. 4

    Straighten the elbow and take the arm out to the side at about shoulder height, palm still facing away and wrist still bent back. Go only as far as stays comfortable.

  5. 5

    Take the thumb gently away from the hand. This is the last small increment and usually the point where a mild pull appears, so stop before any tingling does.

  6. 6

    Hold each position for three to five seconds at most, then flow back through the sequence in reverse. Moving in and out matters far more than any single hold.

How much to do

5 to 10 slow repetitions through the whole sequence

3 to 5 times a day

Short and frequent, never long and hard. Keep the night splint going alongside for the full four to six weeks, since that is the part doing most of the work while these keep the nerve moving.

Stop and get assessed if

Stop immediately and get assessed if any repetition increases your numbness or tingling, because a glide should never be pushed into your symptoms. Get assessed promptly too if numbness has become constant rather than intermittent, if the fleshy bulk at the base of your thumb looks wasted, or if your grip has visibly weakened.

Common mistakes

Treating it as a stretch and parking at end range
A nerve held under sustained tension becomes more irritable, not less, and reacts by producing exactly the symptoms you are trying to settle. The aim is sliding, so you move in and out of each position rather than holding it.
Pushing until you feel the tingling
Reproducing your symptoms is the one thing this exercise must never do. Any increase in numbness or tingling means you have gone past the point where the nerve is gliding freely, so ease back until the sensation is a mild pull and nothing more.
Doing the glides and skipping the splint
Most of the pressure spike inside the tunnel comes from hours of sustained wrist bending while you sleep, which is what the splint prevents and what glides cannot touch. Doing these instead of splinting leaves the main driver untouched.
Doing hundreds of them because they feel easy
Volume is the usual way people flare a nerve with this exercise. Five to ten repetitions a few times a day is the useful dose, and more does not speed anything up.
Ignoring the wrist position you spend the rest of the day in
A few minutes of glides cannot offset seven hours of typing with the wrists cocked upward. Lower the keyboard rather than raising it, leave the fold-out legs folded, and take a micro-break every twenty to thirty minutes.

Making it harder

  • Once the basic sequence is comfortable and symptom free, add a gentle side bend of the head away from the arm at the end position, which adds a little tension along the length of the nerve. Remove it the moment any tingling appears.
  • Let the shoulder settle down away from your ear at the end position rather than shrugging into it, which is a small increase in tension and a useful next step.
  • Add tendon glides for the fingers, moving the hand through a straight hand, hook fist, full fist and tabletop position, which helps the tendons in the tunnel move independently of the nerve.

Making it easier

  • Keep the elbow bent throughout and work only the wrist and fingers. This is a much lower tension version and suits an irritable hand.
  • Cut back to three or four repetitions and stop well before any pull is felt at all, then rebuild the range as the hand tolerates it.
