February 27, 2025 updated by: Başar Öztürk, Fenerbahce University

The Effect of Neck Mobilization vs. Combined Neck and Lumbar Mobilization on Pain and Range of Motion in People With Cervical Disc Herniation: A Randomized Controlled Study

Background To assess the effectiveness of Kaltenborn-Evjenth Orthopedic Manual Therapy (KEOMT) applied to cervical-only mobilization versus both lumbar and cervical regions on pain intensity and range of motion (ROM) in individuals with cervical disc herniation, Methods: Thirty three participants were enrolled in the study. The patients were randomly assigned to two groups. Group A received cervical-only KEOMT while Group B received combined lumbar and cervical KEOMT, Interventions were administered three times a week for four weeks. Pain was measured using the Visual Analog Scale (VAS), ROM was assessed for flexion and lateral flexion, and Neck Pain and Disability Index (NPDI) and Short-Form 36 Health Survey (SF-36) were used for evaluation.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Group A (Cervical mobilization group)
Cervical mobilizations were performed with patients in a supine position. This setup facilitated accurate application of manual therapy techniques. Techniques included Grade 1 mobilizations (pain relief) and Grade 2 mobilizations (soft tissue relaxation). The concave-convex rule guided gliding and translatory movements for optimizing joint mechanics. Manual traction and segmental mobilization were performed with patients in a supine position. The KEOMT included cervical segmental traction and cervical segmental mobilization-flexion and gliding therapy in grade 3. The Convex/Concave Rule was consistently applied in all cases.
Kaltenborn's biomechanical approach to diagnosis and treatment emphasizes ergonomic principles and trial-based techniques. His mobilization methods, classified into Grades I-III, target pain relief (Grades I-II) and joint hypomobility (Grade III) by enhancing glide and tissue elasticity. The Kaltenborn-Evjenth Orthopedic Manual Therapy (KEOMT) further refines this approach using arthrokinematic principles to restore physiological joint motion based on the concave-convex rule.
Experimental: Group B (Combined cervical and lumbar mobilization group)
For segmental flexion mobilization, the patient is positioned on their side with their hips and knees flexed. The therapist places one hand on the vertebrae, positioning the fingers on either the transverse or spinous processes, and the other hand on the sacrum in a similar manner. To facilitate movement, the therapist's chest makes contact with the patient's knees, allowing the pelvis to be guided in a caudal or ventral direction. This technique can be effectively adapted for both cervical and lumbar regions, maintaining consistent application across various spinal segments. For segmental traction, the patient also lies on their side, with their knees flexed toward the abdomen. The therapist hooks their fingers over the proximal transverse processes or the soft tissues in the paravertebral region and applies traction by pulling in opposite directions.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Visuel Analog Scale
Time Frame: Through study completion, an average of 1 year
Pain intensity was evaluated with a visual analog scale (VAS). A 10 cm visual scale was divided into equal segments and numbered from 0 to 10. Patients were instructed that 0 represents no pain, while 10 indicates unbearable pain. Based on this explanation, they were asked to rate their pain intensity accordingly
Through study completion, an average of 1 year
Range of motion
Time Frame: Through study completion, an average of 1 year
A universal goniometer was used to measure joint position and range of motion, following the guidelines of Kendall and the American Association of Orthopedic Surgeons. The assessment was conducted with the patient in a sitting position. Patients were instructed to actively perform movements of cervical flexion, extension, right and left rotation, and right and left lateral flexion, with the corresponding degrees of motion recorded.
Through study completion, an average of 1 year
Neck Pain and Disability Assessment
Time Frame: Through study completion, an average of 1 year
Neck pain and disability were evaluated using the Neck Pain Disability Index (NPDI), a validated tool developed by Vernon and Mior (1991). The index comprises 20 items scored on a Visual Analog Scale (VAS), assessing the impact of neck pain on daily activities, occupational performance, and emotional well-being. Scores range from 0 (no disability) to 100 (complete disability), with higher scores indicating greater functional limitations. This study employed the Turkish version of the NPDI, which has demonstrated reliability
Through study completion, an average of 1 year
Quality of life scale
Time Frame: Through study completion, an average of 1 year
The participants' quality of life was assessed using the Short Form 36 (SF-36), a self-reported scale developed by the Rand Corporation in 1992. The SF-36 evaluates general health status through 36 questions, divided into 8 subscales: physical function, physical role limitations, bodily pain, general health, vitality, social function, emotional well-being, and mental health. Scores on the SF-36 range from 0 to 100, with 0 representing the worst health status and 100 representing the best. The Turkish version of the scale was used in this study
Through study completion, an average of 1 year
