AI summary: who the study is looking for
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for adults with obesity who are already scheduled for laparoscopic sleeve gastrectomy. It will follow their neck posture, neck pain and neck function for 12 months after surgery.
- Age
- 18 to 65 years
- Sex
- Men and women can join.
- Disease stage
- Obesity with a clinical reason for bariatric surgery, scheduled for laparoscopic sleeve gastrectomy at Haydarpasa Numune Training and Research Hospital.
- Earlier treatment
- No treatment is required beforehand. A lateral cervical radiograph taken earlier must be available in the hospital system or national electronic health record.
Main reasons for not taking part
- Previous neck (cervical spine) surgery
- Recent neck injury, neck fracture or severe neck deformity
- Inflammatory rheumatic disease such as rheumatoid arthritis or ankylosing spondylitis
- Neurological disorder such as multiple sclerosis, myopathy or peripheral neuropathy
- Pregnancy or breastfeeding

- Original description
Obesity may contribute to neck pain, altered cervical posture, and impaired cervical function through increased mechanical loading, changes in body alignment, and reduced muscle performance. Although laparoscopic sleeve gastrectomy can produce substantial weight loss, its effects on cervical posture and neck-related function have not been studied comprehensively.Read full original descriptionShow less
Evaluation of Cervical Posture, Cervical Function, and Neck Pain After Laparoscopic Sleeve Gastrectomy: A Prospective Study
Obesity may contribute to neck pain, altered cervical posture, and impaired cervical function through increased mechanical loading, changes in body alignment, and reduced muscle performance. Although laparoscopic sleeve gastrectomy can produce substantial weight loss, its effects on cervical posture and neck-related function have not been studied comprehensively.
This prospective, single-center study will include approximately 25 adults who are already scheduled to undergo laparoscopic sleeve gastrectomy as part of their routine clinical care. The decision to perform surgery and the surgical procedure itself will not be assigned or modified by the study. Participants will be evaluated before surgery and at 3, 6, and 12 months after surgery.
Study assessments will include neck-related disability, neck pain intensity, quality of life, cervical range of motion, cervical muscle strength and endurance, and cervical joint position sense. Existing preoperative lateral cervical radiographs will be reviewed, and a lateral cervical radiograph will be obtained at the 12-month follow-up to assess cervical spinal alignment.
The primary outcome will be the change in Neck Disability Index scores across the scheduled study assessments. The study aims to determine whether weight loss following laparoscopic sleeve gastrectomy is associated with changes in cervical posture, neck pain, and cervical function.
Inclusion: Adults aged 18 to 65 years; Obesity with a clinical indication for bariatric surgery; Scheduled to undergo laparoscopic sleeve gastrectomy at Haydarpasa Numune Training and Research Hospital; Availability of a previously obtained lateral cervical radiograph in the hospital information system or national electronic health record; Willingness and ability to attend the preoperative and 3-, 6-, and 12-month follow-up assessments; Provision of written informed consent.
Exclusion: Previous cervical spine surgery; Diagnosed inflammatory rheumatic disease, such as rheumatoid arthritis or ankylosing spondylitis; History of a neurological disorder, such as multiple sclerosis, myopathy, or peripheral neuropathy; Malignancy or advanced systemic disease, such as advanced heart failure or renal failure; Acute cervical trauma, cervical fracture, or severe cervical deformity; Pregnancy or breastfeeding; Inability to attend the scheduled follow-up visits.
