Pain Neuroscience Education and Vagus Nerve Stimulation on Recovery in Individuals With Rheumatoid Arthritis

Summary

In the context of this randomized controlled study, patients who are diagnosed with Rheumatoid arthritis in Cerrahpaşa Faculty of Medicine Hospital, will be taken into a rehabilitation program by a qualified physiotherapist to improve their pain, pain perception, inflammatory markers and quality of life, with one of the pain neuroscience education, vagal nerve stimulation and traditional exercise interventions. The results of each intervention method will be analyzed and compared at the end of the 8 weeks study protocol.

Pain Neuroscience Education

Many sources in the literature draw attention to patient education as the first stage of treatment and the most common educational technique that focuses on the perception, mechanism and modulation of pain is known as Pain Neuroscience Education (PNE). Patients in this group will take educational sessions about the pain, facilitators of pain, the factors affecting the pain perception and how to deal with chronic pain in rheumatoid arthritis with the help of power point presentations, animation videos, pictures and drawings. Intervention will last for 8 weeks, 2 times per week, in total 16 sessions will be completed. Each session will last 30 minutes in average and at the same time, patients will be advised to perform the given home exercises for 2 times per week. Assessments will be performed before and after the intervention.

OTHER

Vagal Nerve Stimulation

Vagus nerve (cranial nerve X) is the longest and most widely distributed cranial nerve containing sensory, motor, and parasympathetic fibers. It plays an important role in the regulation of cardiovascular, respiratory, immune, endocrine, and autonomic systems, as well as homeostasis. Participants with rheumatoid arthritis will be taken into stimulation sessions for 2 times per week for continuous 8 weeks. Assessments will be performed before study and after the 16 sessions are completed. Since the literature has missing knowledge about the effects of Vagal nerve stimulation in rheumatoid arthritis, the results will highlight the effects on pain and inflammatory markers in this population. Current will be given from the left ear/transauricular area to prevent the side effects in the sessions.

OTHER

Structured Exercises

Structured exercise planned in this study is based on the principles and suggestions of EULAR, by consisting warm-up, basic exercise and warm up sessions by combining different exercise types like aerobic, strengthening flexibility, breathing and definitely by including hand specific exercises. Participants in all three groups will be educated in the first session about the exercises to prevent wrong application and injuries. Afterwards, all groups will continue to their exercises at the home setting. An exercise diary will be asked from patients to control if they continue to their exercises regularly for 2 times for 8 weeks.
