How neck mobility changes after seated cervical extension glide vs downslip glide
Official title: Cervical Rotation Range of Motion Improvements Following Cervical Extension vs Downslip Mobilizations
Run by Missouri State University · NCT07656285 · Data updated 2026-11-12
This study tests whether seated cervical extension glides or supine downslip glides improve neck rotation more and feel more comfortable in healthy adults.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are healthy adults aged 18–45 without neck pain or cervical spine history.
✕Probably not a fit
Individuals with prior neck pain, cervical instability, surgery, neurological issues, or contraindications to mobilization may not benefit.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
Healthy adults aged 18-45 are randomized to receive either seated cervical extension glide or supine downslip glide. Cervical rotation is measured before and after each mobilization using a validated cervical range of motion device, with the same researcher conducting measurements to reduce error. Each participant receives five repetitions per side with short rests, then returns to seated position for post-mobilization rotation testing and rates comfort on a 0–10 scale.
Why it matters
Potential benefit: If successful, the findings could guide clinicians on which mobilization technique offers greater rotation gains and patient comfort.
How similar studies have gone: Previous work has used similar ROM measurements and comfort scales to compare manual techniques, indicating potential for detectable effects.
