Summary
This trial aims to test the effect of tVNS on knee OA pain and autonomic function, measuring pain severity, central pain sensitivity, and heart rate variability.
Who is the study for?
This trial is for adults over 45 with chronic knee pain from osteoarthritis, experiencing an average pain intensity of 4 or higher on a scale of 0 to 10. Participants should have had this pain for at least three months and be able to communicate in English.
What is being tested?
The study tests if ear-based vagus nerve stimulation (tVNS) can reduce knee pain and affect the body's autonomic functions like heart rate variability in people with knee osteoarthritis. It checks tVNS's feasibility, its impact on central nervous system pain mechanisms, and overall satisfaction with the treatment.
What are the potential side effects?
While not explicitly mentioned, potential side effects may include discomfort at the stimulation site, headache, dizziness or changes in heart rate due to the influence of tVNS on autonomic function.

Experimental Treatment
Group I: tVNS groupExperimental Treatment1 Intervention
This will be a single-arm study where all study participants will receive transcutaneous vagus nerve stimulation (tVNS) at the cymba concha of the left ear for 60 minutes. The tVNS parameters will be a below-discomfort-threshold intensity with 25 Hz and a pulse width of 250 uS.
