Carpal Tunnel Syndrome

Numb fingers aren't automatically carpal tunnel, and the most useful clue is which fingers. The median nerve supplies the thumb, forefinger, middle finger and half the ring finger, which means "the little finger and half of the ring finger are unaffected" ². If your little finger is tingling too, that distribution doesn't fit. Worth saying so at your assessment.

A diagnosis isn't made on symptoms alone either: tests are used to rule out other conditions that can drive the same picture, rheumatoid arthritis and an underactive thyroid among them ¹.

If what you have is an ache that worsens with use rather than numbness, our Repetitive Strain Injury (Wrist) page covers a different problem in the same area. The Hand section of our Injury Finder lists the rest.

Carpal tunnel syndrome can often be diagnosed from your history and a hands-on examination, with no further tests ⁹. We tap or press over the median nerve at your wrist to see if it sets off tingling in your fingers, and hold your wrists bent to see whether the numbness comes on ⁹. We also test the feeling in your fingertips with light touch, and check the muscles at the base of your thumb for weakness or wasting ⁹.

Nerve conduction studies measure how well the nerve carries its signal through the tunnel. They're used in some cases to show how severe the compression is and to help guide treatment ^{1 9}. X-rays are mainly for a wrist that's been injured or has bone changes ¹.

The first job is working out what's driving the compression: which fingers are involved, how the night pattern behaves, and what else is contributing. Injury, overuse, arthritis, diabetes, thyroid problems and pregnancy are all recognised contributors ^1,2. Some of those belong with your GP rather than with us, and we'll say so when that's the case.

• Manual therapy: where the strongest evidence sits. A 2025 network meta-analysis of 49 randomised trials ranked it highest of eleven conservative treatments for both short- and medium-term pain relief ⁵. A review of 26 trials found it "faster and equally effective in reducing pain and improving function in the long term compared to surgery", with change in mild-to-moderate cases after as little as two weeks ⁷, though that review graded its own studies' risk of bias only moderate to low ⁷.
• Night splinting: a splint worn overnight keeps the wrist out of the positions that spike the pressure while you're asleep and can't control it. Splinting is effective in the conservative-treatment literature ⁶ and is listed among the standard non-surgical options by both Australian government sources ^1,2. Wearing one for a night or two before a hand-heavy day is also worth trying ¹.
• Changing the load, not just stopping it: identifying which activities, grips and tool positions are feeding the cycle, and adjusting those ^1,2. This is usually where "settled" and "back again in six weeks" part ways.
• Hand rehabilitation: rebuilding grip and thumb control. Because the median nerve serves the thumb muscles, advanced cases lose thumb use and grip strength ².

Two caveats. The evidence supports conservative treatment in mild-to-moderate cases; severe cases are usually treated surgically ⁶. And the 2025 review's authors state plainly that "further research is needed to assess the long-term efficacy and cost-effectiveness of these interventions" ⁵. The evidence is good, but it isn't settled.

Shockwave therapy. Showed a significant benefit versus control in the 2025 network meta-analysis (SMD −1.03; 95% CI −1.86 to −0.20) ⁵. That's one synthesis without a long track record behind it. Worth discussing, not a first move.

Soft-tissue work and mobilisation. Mobilisation, massage and yoga have shown positive effects on symptoms ⁷, though the evidence for soft-tissue techniques is "limited" ⁶.

Taping. A 2023 meta-analysis of 13 studies found only "a weak effect on functionality and pain", with no significant superiority over other physiotherapy techniques or an untreated control for symptom severity, strength or nerve conduction ⁸. If we use it, it's a complementary tool, not the treatment.

Electrotherapy on its own. Assessments of electrotherapy used alone "have shown no conclusive results about their effectiveness" ⁶. We'd rather say so plainly.

Things that exist in the evidence but aren't ours to give. Corticosteroid, dextrose 5% and platelet-rich plasma injections all appear in the research base and ranked competitively for pain relief ^5,6. They're outside a physiotherapist's scope of practice, so we don't prescribe or administer them. If they're worth considering, that's a conversation with your GP or a specialist.

The overall position, stated by the reviewers themselves: no single best technique or combination has been established ⁶.

Carpal tunnel syndrome is a squeezed nerve, not a torn tissue, so The Well Motion Recovery Path™ starts by easing the pressure on it. You move up a phase on what your hand can do, not on a date.

• Reset: settling the nights first. A night splint and changes to the grips and wrist positions that set it off ^1,2, with manual therapy alongside. Expect the nights to ease before the daytime numbness does. We move you on once you sleep through more nights than not.
• Rebuild: hand rehabilitation for grip and thumb control. Expect some tingling after heavier days. We move you on when your hand does what your daily tasks ask of it.
• Return: back to the work, driving and sleep the hand was interrupting. We recheck grip, thumb strength and fingertip feeling, and you leave with a plan for hand-heavy days. Severe cases are usually treated surgically ⁶, so we refer those on.

How long it usually takes. There is no single figure. One review found change after as little as two weeks of manual therapy in mild to moderate cases ⁷. A Cochrane review of 29 splinting trials found low-certainty evidence that 6 months of wear may beat 6 weeks ¹². After surgery, grip strength usually returns by about 2 to 3 months, and complete recovery may take up to a year ⁹.

Some of the risk is built in: the size of your carpal tunnel is partly inherited ⁹. The rest has been studied more than most people expect:

• Forceful, repetitive hand work is the big one. Studies following more than a million workers found carpal tunnel syndrome developed nearly twice as often in jobs with highly repetitive or forceful hand use ¹⁰. Heavy computer use wasn't linked to a higher rate ¹⁰. Changing those tasks so you're not overusing your hands and wrists is the main prevention advice ¹.
• Workstation gadgets are less certain. A review of 11 workplace studies covering new keyboards, mice, wrist rests, ergonomics training and exercise found mixed evidence that any of them prevents it ¹¹.
• Watch how long your wrist stays bent. Symptoms often come on when the wrist is held bent forward or back for too long: holding a phone, driving, reading a book ⁹.
• Look after the conditions linked to it. Diabetes, rheumatoid arthritis and thyroid problems are all associated with carpal tunnel syndrome ^{1 9}, and treating a condition that may be behind your symptoms is part of managing it ¹.
