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.

Study Population

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.

Description

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.

intervention group

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.
Device: Ultrasound (Phyaction 190 I); with a frequency of 3 MHz was used
Intermittent cervical traction (traction force equal 8% of body weight) was applied with the patient lying supine and the head in neutral position.
Other Names:
  • Cervical traction (Eltrac 471); for widening of cervical disc space.
