Carpal Tunnel Syndrome
Also known as: carpal tunnel syndrome, median neuropathy at the wrist, median nerve compression at the carpal tunnel, entrapment neuropathy of the median nerve
Carpal tunnel syndrome is a compressive neuropathy of the median nerve at the wrist. Typical symptoms are paraesthesia, numbness, burning or aching in the thumb, index, middle and radial half of the ring finger, often worse at night, and may progress to impaired dexterity, reduced grip and thenar wasting. Neutral-position nocturnal wrist splinting and corticosteroid injection are established conservative options; persistent sensory loss, thenar weakness, wasting or denervation warrants timely medical or surgical assessment. Acupuncture is adjunctive only — current evidence is low to very low certainty.

Lifestyle & Diet
- •Wear a neutral-position wrist splint at night for a time-limited trial (commonly around six weeks) for mild-to-moderate symptoms; avoid splints holding the wrist in marked flexion or extension, and check fit, skin integrity and circulation.
- •Reduce sustained wrist flexion or extension, forceful gripping, high-repetition tasks and prolonged vibration where practical; alternate tasks and take brief recovery breaks.
- •Adjust keyboard, mouse, handlebars, steering position or hand tools to support a relaxed, neutral wrist; avoid sleeping with the wrist curled beneath the body or head.
- •Trial gentle tendon-gliding or median-nerve-gliding exercises when taught correctly; stop any exercise that produces sustained tingling, increased night waking, weakness or lingering pain.
- •Progress grip or thenar strengthening only when irritability has settled and significant denervation has been excluded; a hand therapist or physiotherapist can individualise splinting and rehabilitation.
- •Optimise diabetes management and seek review of possible thyroid disease, inflammatory arthritis or other systemic contributors; do not smoke.
- •Pregnancy-related symptoms often improve after birth, but severe or progressive neurological loss still requires assessment; sudden generalised swelling with headache, visual change or high blood pressure needs urgent maternity review.
- •Do not apply very hot packs, moxa or ice directly to skin with reduced sensation; do not rely on analgesia or complementary therapy to mask progressive weakness.
Cautions & Contraindications
- •Do not delay urgent medical or surgical referral where progressive median-nerve compression, thenar wasting, persistent sensory loss or acute neurological deterioration is present.[]
- •Do not needle through cellulitis, abscess, open wounds or infected skin.[]
- •Do not needle over acute fractures, unstable trauma or uncontrolled bleeding.
- •Do not perform acupuncture in patients unable to provide informed consent.
- •Use caution with anticoagulants or bleeding disorders; modify local technique.
- •In pregnancy, avoid traditionally contraindicated points (e.g. strong stimulation of LI4, SP6) unless clinically justified and within scope.
- •Avoid aggressive local needling where sensation is impaired; avoid electroacupuncture in patients with implanted pacemakers or contraindicated electrical devices.
- •Chinese herbal medicine requires individual consultation by a qualified practitioner; review pregnancy, breastfeeding, hepatic and renal function, and medication interactions.
- •Exclude prohibited or restricted substances including Má Huáng (Ephedra), Fù Zǐ (Aconitum), Cǎo Wū and Chuān Wū, and any ingredient not permitted under Australian regulations.
When to reassess or seek care again
- •Review after 4–6 treatments or approximately 4–6 weeks.
- •Track pain severity, night waking, paraesthesia frequency, grip strength, thumb opposition and thenar muscle bulk.
- •Refer if symptoms worsen, progressive weakness or thenar wasting develops, sensory loss becomes persistent, symptoms extend beyond the median distribution, or the diagnosis becomes uncertain.
