Physical Therapy on Phrenic Nerve Function

Recruiting

• Conditions: Cervical Disc Lesion; Phrenic Nerve Irritation; Pulmonary Function Test
• Interventions: Device: Ultrasound (Phyaction 190 I); with a frequency of 3 MHz was used

• Registration Number: NCT05817565
• Lead Sponsor: Cairo University

Brief Summary

This study was conducted to investigate the effects of a designed physical therapy program on respiratory function and phrenic nerve activity in cervical disc compression.

Detailed Description

Twenty patients from the Spinal Unite represented the sample of the study. Their mean ages were 43 years and they suffering from acute cervical disc compression at the level of cervical 3, 4, 5. Methods: Evaluation was carried out before and after three months of treatment. It included measuring of pulmonary functions (VC, FVC, FEV1, PEF and MVV) by using spirometer, diaphragmatic excursion and thoracic volume via x-ray and conduction velocity and amplitude of phrenic nerve using electromyography. Treatment program included heat application, ultrasound, cervical traction and diaphragmatic breathing exercises.

Arm && Interventions

Group	Intervention	Description
intervention group	Ultrasound (Phyaction 190 I); with a frequency of 3 MHz was used	Patients underwent physical therapy program 3days/week for three months in the form of * Heat therapy by using infrared on the cervical region for relaxation of spasmed neck muscles, while the patient in sitting position. * While the patient is sitting, the ultrasound was applied on the para spinal muscles of cervical region for controlling pain. * Intermittent cervical traction (traction force equal 8% of body weight) was applied with the patient lying supine and the head in neutral position.

Primary Outcome Measures

Name	Time	Method
pulmonary function test	4 months	to measure vital capacity
