Median Nerve Glides: The Four Exercises, in Full

These are built to coax gentle movement, or glide, out of the nerve. They should stay free of pain, though a sense of stretch or tension is expected, and mild nerve symptoms may come and go while you work through them. Pain, or symptoms that worsen, means stopping and speaking to your clinician.

Run through them two or three times a day and watch whether your symptoms shift. A symptom diary is a genuinely useful way to track that: a few lines on what you did, how the day or the night went, and a pain score out of 10 is enough.

Three of those instructions are doing more work than they look like they are.

"They should not be painful." Nerve tissue responds badly to being provoked. A glide that leaves your hand buzzing for an hour afterwards has been taken too far, and repeating it daily tends to make the nerve more sensitive rather than less. Tension you can feel and that disappears the moment you release is the target.

"Only try the slider once your symptoms are settling." The slider is the most demanding of the four because it loads the nerve at both ends at once. Starting there is the most common way people make themselves worse.

The symptom diary. Carpal tunnel symptoms fluctuate week to week on their own, which makes it genuinely hard to tell whether an exercise is helping. A few lines a day plus a pain score out of ten turns a vague impression into something you can actually judge after a fortnight.

Worth being straight about this. The Cochrane review of exercise and mobilisation interventions for carpal tunnel syndrome concluded that the effectiveness and duration of benefit of exercises and mobilisation for this condition remain unknown, on the basis of small trials of limited quality. That is an honest "we do not know", rather than evidence that they fail.

A 2016 systematic review in the Journal of Manipulative and Physiological Therapeutics looked specifically at nerve gliding and reached a more useful practical conclusion: standard conservative care, meaning a night splint plus tendon or carpal mobilisation, remains the better bet for pain and function, and nerve gliding is worth adding on top of it rather than using instead of it. Where trials combined gliding with conventional treatment, symptom severity and function improved more than with conventional treatment alone.

So the reasonable expectation is: a low-cost addition that may shorten how long symptoms take to settle, sitting alongside a night splint and, where the cause is obvious, a change to what is aggravating it. If these exercises are the only thing being done, they are being asked to carry more than the evidence supports.

The median nerve can be irritated anywhere along its route, and the hand symptoms can be near-identical wherever the trouble starts. Several patterns point away from the carpal tunnel:

• Symptoms in the little finger. The median nerve does not supply it. Little and ring finger symptoms point to the ulnar nerve, usually at the elbow.
• Numbness over the palm itself. The branch supplying the palm leaves the nerve before the carpal tunnel, so palm numbness suggests the problem is higher up.
• Neck movement changes the hand symptoms. That points to a cervical nerve root, and neck-based treatment rather than wrist splinting.
• Weakness and wasting at the base of the thumb. Visible muscle loss in that pad is a reason for prompt medical assessment rather than a longer trial of exercises.

Our article on trapped muscle pain covers how nerve symptoms are separated from muscular ones, and carpal tunnel surgery recovery covers what happens when conservative treatment has run its course.

The question that comes up in the room, almost word for word, is: "will these actually stop me needing the operation?"

The honest answer depends on which group you are in, and that is what testing sorts. Symptoms that are intermittent, mostly nocturnal, and provoked by wrist position tend to respond well to a night splint plus gliding, and a good share of those people never need surgery. Constant numbness, a thumb pad that has visibly lost bulk, or strength that is measurably down are a different situation, and delaying assessment there risks changes that do not fully reverse. At PhysioHub in Uckfield, the useful part of the appointment is usually establishing which of those two you are, and whether the symptoms are coming from the wrist at all rather than the neck.

If you are unsure whether your hand symptoms are carpal tunnel, the neck, or something else, a free discovery call is a sensible way to work out what you need before booking anything.

How often should I do median nerve glides?
Two or three times a day. More is not better with nerve tissue.

Should nerve glides tingle?
Mild symptoms coming and going during the exercise is expected. Symptoms that persist afterwards mean you have gone too far.

How long before they help?
Give it two to four weeks with a symptom diary. Nerve symptoms fluctuate on their own, so a diary is what makes the answer readable.

Can nerve glides make carpal tunnel worse?
They can if pushed into pain, or if the slider is started too early. Both are avoidable by following the order on the sheet.

Do I still need a splint?
For most people with night symptoms, yes. The evidence for a night splint is stronger than the evidence for gliding, and they work well together.
