Immediate neck manual therapy effects on atlas position and neck muscles

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This randomized, repeated-measures study examines the immediate effects of thrust long-axis manipulation of the C1-C2 junction on craniovertebral alignment and the obliquus capitis inferior muscle. Participants undergo two upper cervical manual therapy interventions with measurements captured right away to assess changes in CVA, atlas position, and OCI morphology using ultrasound. The design allows within-subject comparison of the interventions to determine short-term biomechanical responses. The study is conducted at Florida Gulf Coast University and does not report a multi-site or powered comparative framework.
