Official title
Effectiveness of Noninvasive Phrenic Nerve Neuromodulation in Subjects With Right Shoulder Pain and Hepatobiliary Visceral Comorbidity.
Overview
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.
Detailed description
Approximately 80% of patients with liver disease suffer chronic pain and fatigue, which can lead to sensitization of the central and peripheral nervous system. Central sensitization is an increase in the responsiveness of neurons within the central nervous system, which can lead to generalized pain hypersensitivity. It has been shown that some lesions or inflammatory processes can trigger changes in the nervous system, generating persistent pain.
According to the theory of visceral referred pain, there are visceral and musculoskeletal stimuli that converge in higher centers capable of producing referred pain in regions where metameric innervation is shared. This raises the possibility that altered visceral mechanisms may provoke and chronify musculoskeletal pain.
According to this theory, people with structural or functional hepatobiliary pathologies may have referred pain in the right metameric territory of C2-C3-C4-C5, which may generate pain in the shoulder on the same side. This is due to the fact that the phrenic nerve sensitively innervates Glisson's capsule, so any affectation of this structure can generate afferent stimuli to the previously mentioned metameric levels.
The phrenic hypothesis plays a very important role today, having as its main "endorsement" the analgesic techniques of phrenic blockade used for shoulder pain after hepatectomy. In order to eliminate this post-operative shoulder pain, electrical or medical nerve blocks are used.
Interventions
- Device Phrenic nerve neuromodulation
The intervention group will receive the usual physiotherapy treatment at the health center and will also receive neuromodulation on the phrenic nerve at its exit through the anterior cervical region. The neuromodulation technique will be applied for 10 minutes. - Procedure common Physical therapy
the usual treatment of the center consisting of manual therapy, exercise and thermotherapy will be performed.
Primary outcome measures
- Numeric Pain Rating Scale [Time frame: pre-treatment, 1 week, 4 week, 12 week.]
Secondary outcome measures (4)
- Algometry [Time frame: pre-treatment, 1 week, 4 week, 12 week.]
- Goniometry passive [Time frame: pre-treatment, 1 week, 4 week, 12 week.]
- Quick Dash questionnaire [Time frame: pre-treatment, 1 week, 4 week, 12 week.]
- Goniometriy active [Time frame: pre-treatment, 1 week, 4 week, 12 week.]
