Cervical atlanto-occipital joint x-ray in open-mouth position or CT scan reveals an atlanto-occipital distance (AOD) of 2\u2005mm\u2009&amp;lt;\u2009AOD\u2009&amp;lt;\u20095\u2005mm, or a bilateral atlanto-occipital lateral distance (B-LAD)\u2009\u2265\u20092\u2005mm. Although traditional manipulative and bone-setting techniques in Traditional Chinese Medicine have demonstrated clinical benefits, robust empirical evidence remains limited. Musculoskeletal ultrasound (MUSU), as a modern diagnostic modality, has gained popularity for assessing musculoskeletal disorders.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This study utilized a randomized controlled trial design, where eligible patients diagnosed with AARS were, randomly assigned (1:1) to either a treatment group (gentle manipulative technique combined with continuous traction) or a control group (traction plus cervical collar immobilization). The treatment group received treatment twice daily, five days per week, for two weeks. The control group received the same traction protocol but wore a neck brace immediately after each traction treatment. The primary outcome measure was musculoskeletal ultrasound (MUSU) findings, while secondary outcomes include Visual Analogue Scale (VAS) pain scores and Neck Disability Index (NDI) scores. Both groups were assessed at baseline, post-treatment, two weeks, and six months after treatment.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
