Effectiveness of Noninvasive Phrenic Nerve Neuromodulation in Shoulder Pain and Hepatobiliary Visceral Comorbidity.
Pain, particularly shoulder pain, is a social and economic problem worldwide. Although visceral pathology is not yet taken into account in the diagnosis of these pains, it is likely that on numerous occasions the hepatobiliary visceral condition causes referred pain in the metameric area belonging to the shoulder due to the involvement of the phrenic nerve. Therefore, the aim of this project is to study the response of treatment by neuromodulation of the phrenic nerve for shoulder pain in patients with associated hepatobiliary pathologies, assessing the possible visceral involvement in the symptomatology.
- EligibilityCriteria: Inclusion Criteria:  Over 18 years of age and under 64 years of age. Subjects presenting right shoulder pain at the time of enrollment in the study. Presentation of a hepatobiliary visceral disorder that may justify the visceral etiology of the pain. That they agree to participate in the project by signing the informed consent form.  Exclusion Criteria:  Patients with chronic pain due to other diseases such as malignant disease. Patients with rheumatic diseases. Cutaneous infection in the area of pain. Disease of neurological, traumatic, oncologic, or infectious origin that rules out the visceral origin of the pain. Uncooperative subject. Severe psychiatric disease. Loss of cognitive capacity. Contraindication to electrotherapy. - HealthyVolunteers: No - Gender: All - MinimumAge: 18 Years - MaximumAge: 64 Years - StdAgeList: Adult
