Vagus Nerve Stimulation Effect in Frozen Shoulder Treatment

This is a randomized, double-blind (participants and outcome assessors), sham-controlled study. Participants will be recruited from a university hospital. Volunteers diagnosed with frozen shoulder who meet the inclusion criteria and are referred by an orthopedics and traumatology specialist will be included. The study will be conducted in accordance with the ethical principles of the Declaration of Helsinki. Participants who provide written informed consent and meet the inclusion criteria will be randomized in a 1:1 ratio to either exercise therapy combined with active transcutaneous Vagus Nerve Stimulation (tVNS) or exercise therapy combined with sham-controlled tVNS.
