Evaluating the Addition of Low-Level Laser Therapy to Splint Treatment for Adults with Trigger Finger in a Randomized, Double-Blind Clinical Trial

What this Trial Is About

Trigger finger, also called stenosing tenosynovitis, is a common hand disorder causing painful finger locking or catching during movement. This condition may present with pain and stiffness in mild cases, or locked fingers in severe cases. The study aims to evaluate the effects of adding low-level laser therapy LLLT, a treatment that uses light to promote healing and reduce inflammation, to splint treatment for adults with trigger finger, comparing clinical and ultrasound outcomes between active and sham LLLT groups. Participants will be randomly assigned to receive either active LLLT or sham LLLT three times a week for 4 weeks, totaling 12 sessions. Both groups will use a metacarpophalangeal joint blocking splint on the affected finger continuously for 4 weeks. During treatment, participants will wear headphones and an eye mask to maintain blinding. The LLLT uses a device with specific wavelength and power settings, while the sham group receives identical treatment with the device turned off. Participants may continue normal activities while avoiding aggravating movements and may use paracetamol as needed. Before and after treatment, researchers will collect clinical information and assess outcomes including pain intensity, triggering severity and frequency, hand function questionnaires, grip strength, patient satisfaction, and ultrasound measurements of finger structures. These assessments will occur at baseline, immediately after treatment, and at 1 and 3 months post-treatment. Compliance with splint use will be tracked with a daily diary. The study monitors participants closely to evaluate the combined treatment effects over several months.
