Effet de l'attelle nocturne et à temps plein pour le syndrome du canal carpien (FINCROSS)

29 septembre 2026 mis à jour par: Tampere University Hospital

Effet de l'attelle nocturne et à temps plein pour le syndrome du canal carpien : un essai de supériorité croisé multicentrique, à trois périodes et randomisé (FINCROSS - Essai croisé finlandais pour le syndrome du canal carpien)

Carpal tunnel syndrome is a common compression neuropathy of upper extremities. Its usual symptoms are pain, numbness and tingling of fingers, which tend to be worse at night. Splinting the wrist with an external orthosis is usually a first-line treatment provided to most people with mild to moderate disease.

The FINCROSS trial (randomized cross-over trial) aims to assess the effect of night-time and full-time splinting in comparison with no-treatment. It also aims to identify possible subgroups of people who would benefit from splinting, as well as assess if positive response to splinting is associated with subsequent lower need of surgery.

The trial will recruit 110 people with carpal tunnel syndrome in Finland. Each participant will undergo all three treatment periods in a randomised order: 1) splinting at night-time for six weeks, 2) splinting both day and night for six weeks; and 3) be assessed under a six weeks long control period of no-treatment.

Each treatment period will be separated with a three-week washout period. Therefore, the whole treatment sequence for each participant lasts 24 weeks after randomization. The participant will be followed-up to 1 year after the randomisation.

Additionally, the participants will get instructions for self-administered stretching exercises to perform throughout the study. All participants will be asked to avoid any intervention administered or supervised by medical personnel (such as structured supervised exercises, manual therapy, steroid injections, surgery, etc.).
