Evaluation and Treatment of Adhesive Capsulitis Using Non-invasive Neurostimulation Devices Prise En Charge Des Atteintes Proprioceptives Chez Une Population Avec Capsulite Rétractile

What this Trial Is About

Researchers are studying individuals with adhesive capsulitis, also known as frozen shoulder, to understand how this condition affects the brain and muscle connections involved in shoulder movement. The study aims to compare brain and nerve responses between people with this condition and healthy volunteers, and to evaluate whether a special vibration treatment combined with exercises can help improve shoulder function and sensory processing. Participants will be randomly assigned to receive one of two tendon vibration treatments twice a week for three weeks, with six sessions in total. One group will receive vibrations at 80 Hz designed to create kinesthetic illusions, while the other group will receive a placebo vibration at 40 Hz that does not create these illusions. Both groups will also follow a daily standardized exercise program. The study includes two baseline assessments before treatment and two follow-up evaluations after treatment. During the study, participants will complete questionnaires about shoulder pain and disability, undergo ultrasound scans, and have their active and passive shoulder movements measured. Neurophysiological tests, including transcranial magnetic stimulation and a standardized kinesthetic illusion procedure, will assess brain and nerve function. Researchers will track changes in motor thresholds, muscle response times, and the clarity and direction of illusions. The total participation time spans about two months from baseline to follow-up.
