Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Cervical traction has long been defined as a distracting force that separate the cervical segments and relieve nerve roots compression. Yet, there is lack of knowledge that reports the effects of different traction decompression angles and determines the proper angle of pull among different angles of decompression system

Participants Outcome Assessors

patients with cervical radiculopathy, caused by cervical paramedian disc protrusion at C5-C6 or C6-C7 levels will participate in the study. They will be assigned randomly into three equal groups; A, B and C.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

traction therapy from neutral position

Patients in this group will receive traction decompression from neutral neck position with rope angle (0°)

Group Type ACTIVE_COMPARATOR

Cervical Traction from different angles

Intervention Type OTHER

Intermittent traction will be applied, maximum force will be 16 kg, minimum force will be 12 kg, traction cycle of each minute consists of 20 seconds static traction at the maximum force then released down to the minimum force for 20 seconds then repeated for 20 seconds static traction. Traction session time will be 15 minutes, and the traction force will be increased progressively with speed (50%) of increment of force

traction therapy from lateral bending

patients will undergo traction decompression from (30°) lateral bending of the neck toward the non-affected side

Group Type ACTIVE_COMPARATOR

Cervical Traction from different angles

Intervention Type OTHER

Intermittent traction will be applied, maximum force will be 16 kg, minimum force will be 12 kg, traction cycle of each minute consists of 20 seconds static traction at the maximum force then released down to the minimum force for 20 seconds then repeated for 20 seconds static traction. Traction session time will be 15 minutes, and the traction force will be increased progressively with speed (50%) of increment of force

traction from flexion with lateral bending and rotation

patients will be treated with traction decompression from (15°) neck flexion, (30°) lateral bending toward non- affected side and (15°) rotation to the affected side.
