Carpal tunnel syndrome: acupuncture seeks its place in the fight against pain

At first, it's "just" a troublesome wrist. Then come the tingling, the numbness, that nighttime pain that wakes you up and eventually spreads throughout the day, especially when the movements are repetitive at work or at home. Carpal tunnel syndrome, compression of the median nerve, often follows this well-established pattern.

In France, the standard treatment remains clear: adaptation of movements and ergonomics, night rest splint, analgesics or anti-inflammatories as appropriate, corticosteroid injections when it is necessary to calm the fire (often transiently) and decompression surgery for severe or resistant forms.

Between relief and medical caution, the right timing makes all the difference.

In this well-established treatment pathway, acupuncture regularly reappears, more as a complementary treatment than a miracle cure. A recent meta-analysis concludes that it can improve symptoms, pain, and certain measured parameters, while also noting that the evidence remains limited. In practice, acupuncturists emphasize a very practical point: act early, when symptoms are still mild, and combine the sessions with wearing a night splint. "Ideally before injections, which are recommended and effective, but have side effects," summarizes Dr. Olivier Goret. Protocols often call for 8 to 15 sessions, with several appointments per week, sometimes including electroacupuncture, a low-frequency current intended to enhance the stimulation.

The golden rule remains, the one that separates comfort from risk: don't let a complementary approach delay validated treatment when the warning signs turn red. Atrophy of the thumb muscles, difficulty moving the first three fingers, motor deficits, pain that sets in and erodes function… at these points, surgery becomes the obvious choice. Acupuncture, for its part, aims to be a pain-relieving crutch for some patients, in a period where non-pharmacological strategies are as appealing as they are demanding proof of their effectiveness. The debate now hinges on a word everyone understands: for whom, and when.
