A Systematic Review of Case Reports on the Neck-Tongue Syndrome

<i>Background and Objectives</i>: Neck-tongue syndrome (NTS) is rare, and characterized by unilateral upper neck or occipital pain and paresthesia in the ipsilateral hemisphere of the tongue due to neck movement. Treatment for NTS is mainly conservative, but the symptoms, causes, and rationale for treatment remain controversial. This study aimed to provide a framework for NTS treatment in clinical practice based on recent treatment directions. <i>Materials and Methods</i>: Case reports published from the past 20 years to August 2021 were searched through MEDLINE, EMBASE, and PEDro databases. Since there is no established management for NTS, the search terms were neck-tongue syndrome and case reports. The Critical Appraisal Checklist for Case Reports was used for the quality assessment of case reports. Through descriptive analysis, NTS symptoms, interventions, and results were reviewed. <i>Results</i>: Among the 16 studies searched, six case reports were selected and analyzed based on eight criteria. Symptoms included neck pain and ipsilateral tongue paralysis when the head was turned. As an intervention, six and four studies showed immediate symptom relief through manual therapy and exercise, respectively. <i>Conclusions</i>: Based on the reviewed evidence, management through physical therapy and chiropractic therapy with conservative methods such as manual therapy and exercise for patients with neck-tongue syndrome is recommended.
