Abstract: | Chronic refractory gastrointestinal (GI) motility disorders are a significant burden on the healthcare system, acting as a large public health issue with significant impact on the quality of life in both the pediatric and adult population. Control systems of gastrointestinal motility are complex and involve coordination of smooth muscle contraction and relaxation, which the autonomic nervous system is largely responsible for. Gaps in the diagnosis process, such as overlooking autonomic function, has left patients with diminished quality of life and limited treatment options. Many patients in the clinic have experienced injury within the spinal cord and we hypothesized that GI symptoms might be related to spinal injury causing disruption of sensory and/or motor nerves of the autonomic nervous system. Our objective became to better understand the specific location and nature of spinal injuries and GI symptoms, as completed through the development of a self-report questionnaire. Main findings suggest symptoms indicative of T3-T9 and T10-L2 spinal pathology. COVID-19 did not allow for in-clinic neuromodulation with autonomic assessments, resulting in experiments remotely assessing at-home neuromodulation treatment for GI symptoms with suspected spinal autonomic dysfunction. At-home neuromodulation was not suitable for many patients, but those who were able to manage it showed highly promising results. After years of suffering, transcutaneous electrical nerve stimulation alleviated symptoms, particularly postprandial abdominal pain, constipation, vomiting and nausea. I discuss what we learned to set us up for successful at-home treatment, and we will use all information to design randomized controlled trials to prove the benefit of TENS. The present work offers significant information on the relationship of thoracolumbar spinal pathology and complex GI symptoms, which is now used in the clinic in the diagnosis process of GI dysmotility. In addition, we have learned how to conduct at-home treatment using TENS, which allows us to execute future studies. |
