This is a retrospective reporting of 7 adult patients (4 males and 3 females, 28\u201342 years) treated for cervical hypolordosis. These subjects received Chiropractic BioPhysics\u00ae (CBP\u00ae) rehabilitation and then were involved in a rear-end MVC. All cases had radiographic assessment that quantified the buckling of the cervical spine, presumably resulting directly from the CAD trauma. After an average of 3 years and 9 months (range: 1\u20137.6 years) following their initial program of care, the 7 patients sought care for a second time after the MVC. At this time, compared with their previously recorded post-treatment spine radiographs, there was an average 18.7\u00b0 (range: 7.6\u201335.4\u00b0) reduction in cervical lordosis, a 9.2 mm (range: 3.6\u201319.8 mm) increase in anterior head translation (AHT), an 11.3\u00b0 (range: 0.2\u201319.9\u00b0) decrease in the atlas plane line (APL), as well as a 35.7% (range: 22\u201352%) average neck disability index score (NDI) measured after the MVC. After the crash, a second round of CBP rehabilitation was administered, resulting in an average 15.1\u00b0 improvement in cervical lordosis, 10.9 mm reduction in AHT, 10.4\u00b0 increase in APL, and a 23.7% drop in NDI after an average of 35 treatments over 9 weeks. Treatment was universally successful, as an average 80% re-establishment of the lordosis toward its pre-injury state was found. There were no adverse events reported. This case series demonstrates that motor vehicle collisions may alter the alignment of the cervical spine. Rehabilitation of the cervical curve using extension traction improved the patients\u2019 initial pre-crash alignments toward their pre-injury alignments and was likely responsible for improvement in the patients\u2019 conditions. Clinical trials are needed to confirm these findings.<\/jats:p>","DOI":"10.3390\/jcm12196414","type":"journal-article","created":{"date-parts":[[2023,10,9]],"date-time":"2023-10-09T07:37:50Z","timestamp":1696837070000},"page":"6414","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Positive Outcomes Following Cervical Acceleration-Deceleration (CAD) Injury Using Chiropractic BioPhysics\u00ae Methods: A Pre-Auto Injury and Post-Auto Injury Case Series"],"prefix":"10.3390","volume":"12","author":[{"given":"Tim C.","family":"Norton","sequence":"first","affiliation":[{"name":"Private Practice, Shoreline, WA 98133, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3117-7330","authenticated-orcid":false,"given":"Paul A.","family":"Oakley","sequence":"additional","affiliation":[{"name":"CBP Nonprofit, Eagle, ID 83616, USA"},{"name":"Kinesiology and Health Science, York University, Toronto, ON M3J 1P3, Canada"},{"name":"Private Practice, Newmarket, ON L3Y 8Y8, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jason W.","family":"Haas","sequence":"additional","affiliation":[{"name":"CBP Nonprofit, Eagle, ID 83616, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6671-7106","authenticated-orcid":false,"given":"Deed E.","family":"Harrison","sequence":"additional","affiliation":[{"name":"CBP Nonprofit, Eagle, ID 83616, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,10,9]]},"reference":[{"key":"ref_1","first-page":"1S","article-title":"Scientific monograph of the Quebec Task Force on Whiplash-Associated Disorders: Redefining \u201cwhiplash\u201d and its management","volume":"20","author":"Spitzer","year":"1995","journal-title":"Spine"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"2489","DOI":"10.1097\/00007632-199711010-00005","article-title":"Whiplash produces an S-shaped curvature of the neck with hyperextension at lower levels","volume":"22","author":"Grauer","year":"1997","journal-title":"Spine"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1016\/j.clinbiomech.2003.09.006","article-title":"Cervical spine curvature during simulated whiplash","volume":"19","author":"Panjabi","year":"2004","journal-title":"Clin.
