An interventional study of Structured Postoperative Rehabilitation Program and Standard Postoperative Follow-up in Cervical Disc Disease, Cervical Radiculopathy and Postoperative Dysphagia, sponsored by Istanbul Medipol University Hospital. Not yet recruiting. Open to participants aged 18 Years to 70 Years. Per ClinicalTrials.gov, last updated 2026-09-11.
Sponsored by Istanbul Medipol University Hospital · Not applicable, Interventional, and Treatment
Anterior cervical discectomy and fusion (ACDF) is a commonly performed surgical procedure for cervical disc herniation, cervical radiculopathy, and degenerative cervical spine disorders. Although surgery may reduce pain and neurological symptoms, some patients experience swallowing difficulties, neck pain, restricted neck movement, reduced respiratory muscle strength, and impaired quality of life after surgery.
The purpose of this randomized controlled study is to determine whether a structured postoperative rehabilitation program improves swallowing function, respiratory muscle strength, pulmonary function, neck-related disability, pain, cervical range of motion, and health-related quality of life in adults who have undergone single- or two-level ACDF.
A total of 60 eligible participants will be randomly assigned in a 1:1 ratio to either a structured rehabilitation group or a standard postoperative follow-up group. The structured program will include breathing exercises, inspiratory muscle training, swallowing and safe feeding education, cervical and scapular exercises, postural training, upper-extremity exercises, walking, and gradual physical activity. Participants in the control group will receive the standard postoperative recommendations provided by the surgical team.
Assessments will be conducted before the rehabilitation program and during postoperative follow-up. The primary outcome will be swallowing difficulty measured using the Eating Assessment Tool-10. Additional outcomes will include dysphagia severity, oral intake level, respiratory muscle strength, spirometric pulmonary function, neck pain, neck-related disability, cervical range of motion, health-related quality of life, treatment adherence, and adverse events.
This study is planned as a prospective, single-center, assessor-blinded, parallel-group randomized controlled clinical trial. The study will include 60 adults aged 18 to 70 years who have undergone elective single- or two-level anterior cervical discectomy and fusion (ACDF) for degenerative cervical disc disease, cervical disc herniation, and/or cervical radiculopathy.
After postoperative clinical stabilization and approval for rehabilitation by the responsible surgeon, eligible participants who provide written informed consent will be randomly assigned in a 1:1 ratio to one of two groups: a structured rehabilitation group or a standard postoperative follow-up group. A computer-generated randomization sequence will be prepared by an independent researcher who is not involved in outcome assessment. Allocation concealment will be maintained using sequentially numbered, opaque, sealed envelopes. Because of the nature of the intervention, participants and the treating physiotherapist cannot be blinded. However, outcome assessments will be conducted by a physiotherapist who is blinded to group allocation.
The structured rehabilitation program will be delivered under physiotherapist supervision and supported by a daily home exercise program. The program will include diaphragmatic breathing, thoracic expansion and breathing control exercises, inspiratory muscle training, controlled expiration and coughing techniques, safe swallowing and feeding-position education, individualized oropharyngeal exercises, cervical neutral-position and posture training, scapular stabilization, low-intensity deep cervical flexor activation, pain-free cervical range-of-motion exercises within surgeon-approved limits, upper-extremity mobility and stretching exercises, walking, and gradually increased physical activity.
Inspiratory muscle training will begin at approximately 30% of the participant's baseline maximal inspiratory pressure. Training intensity may be increased according to participant tolerance, perceived exertion, and clinical findings. Swallowing rehabilitation will be individualized according to dysphagia severity. Participants with marked dysphagia, suspected aspiration, or coughing during swallowing will be referred for appropriate specialist assessment. All cervical exercises will comply with the postoperative restrictions established by the surgeon.
Participants assigned to the control group will receive the surgical team's standard postoperative recommendations, including wound care, cervical collar use when indicated, advice regarding daily activities, short-distance walking, and basic permitted movements. They will not receive the structured inspiratory muscle training, swallowing rehabilitation, or supervised cervical-scapular exercise program during the study period. Any additional treatment received outside the study will be documented.
The primary outcome will be swallowing-related symptoms measured using the Eating Assessment Tool-10 (EAT-10). Secondary outcomes will include the Bazaz Dysphagia Grading System, Functional Oral Intake Scale, maximal inspiratory and expiratory pressures, forced vital capacity, forced expiratory volume in one second, FEV1/FVC ratio, peak expiratory flow, Numerical Rating Scale for pain, Neck Disability Index, cervical range of motion, and the 36-Item Short Form Health Survey. Treatment adherence, additional treatments, postoperative complications, and adverse events will also be recorded.
Outcomes will be assessed before the rehabilitation program and during postoperative follow-up. The principal analysis will compare changes over time between the structured rehabilitation and standard follow-up groups. The study will also examine the relationships between changes in dysphagia, respiratory muscle strength, neck function, pain, and health-related quality of life.

Change in Eating Assessment Tool-10 Total Score
Swallowing-related symptoms will be assessed using the Eating Assessment Tool-10 (EAT-10), a 10-item patient-reported questionnaire. Each item is scored from 0 (no problem) to 4 (severe problem), providing a total score ranging from 0 to 40. Higher scores indicate more severe swallowing-related symptoms. A total score of 3 or higher indicates abnormal swallowing-related symptoms. The primary comparison will be the change in the EAT-10 total score from postoperative week 1 to postoperative week 8 between the two groups.
Time frame: Postoperative week 1 (baseline), postoperative week 4, and postoperative week 8
Change in Bazaz Dysphagia Grade
Dysphagia severity will be classified using the Bazaz Dysphagia Grading System. Swallowing difficulty for solid and liquid foods is classified into four categories: none (0), mild (1), moderate (2), or severe (3). Higher grades indicate more severe dysphagia.
Time frame: Postoperative week 1, postoperative week 4, and postoperative week 8
Change in Functional Oral Intake Scale Score
Functional oral intake will be assessed using the Functional Oral Intake Scale (FOIS). The scale ranges from level 1 (no oral intake) to level 7 (total oral intake without restrictions). Higher scores indicate greater functional oral intake and independence.
Time frame: Postoperative week 1, postoperative week 4, and postoperative week 8
Change in Maximal Inspiratory Pressure
Inspiratory muscle strength will be assessed by maximal inspiratory pressure using a portable respiratory pressure measurement device. At least three acceptable measurements will be performed, and the highest acceptable value will be recorded in centimeters of water (cmH2O). Higher values indicate greater inspiratory muscle strength.
Time frame: Postoperative week 1, postoperative week 4, and postoperative week 8
Change in Maximal Expiratory Pressure
Expiratory muscle strength will be assessed by maximal expiratory pressure using a portable respiratory pressure measurement device. At least three acceptable measurements will be performed, and the highest acceptable value will be recorded in centimeters of water (cmH2O). Higher values indicate greater expiratory muscle strength.
Time frame: Postoperative week 1, postoperative week 4, and postoperative week 8
Change in Neck Pain Intensity
Neck pain intensity at rest and during activity will be assessed using an 11-point Numerical Rating Scale ranging from 0 (no pain) to 10 (worst imaginable pain). Higher scores indicate greater pain intensity.
Time frame: Postoperative week 1, postoperative week 4, and postoperative week 8
Change in Neck Disability Index Score
Neck-related disability will be assessed using the Neck Disability Index. The questionnaire contains 10 sections, each scored from 0 to 5, providing a total score ranging from 0 to 50. Higher scores indicate greater neck-related disability.
Time frame: Postoperative week 1, postoperative week 4, and postoperative week 8
Change in 36-Item Short Form Health Survey Scores
Health-related quality of life will be assessed using the 36-Item Short Form Health Survey (SF-36). The instrument evaluates eight domains: physical functioning, role limitations due to physical health, role limitations due to emotional problems, energy/fatigue, emotional well-being, social functioning, pain, and general health. Each domain is transformed to a score ranging from 0 to 100, with higher scores indicating better health-related quality of life.
Time frame: Postoperative week 1, postoperative week 4, and postoperative week 8
