Transauricular Vagus Nerve Stimulation for Chronic Whiplash Associated Disorders

Approximately 50% of people with chronic whiplash-associated disorders (WAD) continue to report the presence of symptoms 12 months post-injury. These symptoms include high levels of pain and disability as well as psychological symptoms such as post-traumatic stress. The nervous system may also be affected, specifically the autonomic nervous system which is responsible for regulating heart rate and blood pressure. An important part of the autonomic system is the vagus nerve, which helps regulate pain and stress responses. Treatment of this nerve via transauricular vagal nerve stimulation (taVNS) has been shown to improve health outcomes in many pain conditions such as chronic low back pain and postural tachycardia syndrome. TaVNS works by sending mild electrical pulses through the ear. This project aims to explore whether or not taVNS can help people with chronic whiplash-associated disorders (WAD) feel better. The first goal is to evaluate the safety and feasibility of taVNS. The investigators are interested in learning how many people with chronic WAD participate in the study and how many complete the full treatment, as well as ensuring that the treatment does not cause any serious side effects. An additional goal is to evaluate the effects of taVNS on neck pain intensity and associated disability, pain sensitivity, heart rate variability, blood pressure, quality of life, post-traumatic stress, stress, anxiety, and depression as measured by questionnaires and physical asse…
