Changes in Cervical Posture, Cervical Function, and Neck Pain After Sleeve Gastrectomy
Evaluation of Cervical Posture, Cervical Function, and Neck Pain After Laparoscopic Sleeve Gastrectomy: A Prospective Study
Source: ClinicalTrials.gov · Last updated 28 Sept 2026
Brief summary (registry, in English)
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.
