Is this trial a fit for you?

Likely a good fit

Adults aged 18–65 with obesity scheduled for laparoscopic sleeve gastrectomy and with a preexisting lateral cervical radiograph available.

Probably not a fit

Patients without significant changes in neck posture or function after surgery may not experience noticeable neck-related benefits.

What this trial studies

This is a prospective, single-center observational study enrolling about 25 adults with obesity who are scheduled for laparoscopic sleeve gastrectomy. Participants will be assessed before surgery and at 3, 6, and 12 months after surgery to measure neck-related disability, neck pain intensity, quality of life, cervical range of motion, and neck muscle strength and endurance. The study uses standard clinical tools such as the Neck Disability Index, pain scales, SF-12, inclinometry, and a handheld dynamometer to characterize changes over time. The surgical procedure will be conducted as part of routine care and will not be altered by the research. Data will help clarify whether weight loss and postural changes after sleeve gastrectomy influence cervical spine health and function.

Why it matters

Potential benefit: If successful, the study could clarify potential neck-related benefits or limitations associated with sleeve gastrectomy and guide post-operative care for neck health.

How similar studies have gone: Prior bariatric surgery studies report improvements in some musculoskeletal symptoms, but prospective data on cervical posture and neck function are limited and this study addresses that gap.
