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.

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.

Inclusion Criteria:

• suffered from cervical disc compression for 6-8 months.
• patients examined and referred by physician.

Exclusion Criteria:

• Any cardio pulmonary disorders which may alter pulmonary function.
• They did not receive any physical therapy program prior to their participation in the study.

study was conducted on 20 patients with compression of the cervical disc at the level of 3, 4, and 5. Their mean age was 43 years; mean weight was 75 kg and mean height was 170cm.They suffered from cervical disc compression for 6-8 months.
