Temporomandibular disorders and cervicogenic dizziness: Relations between cervical range of motion and clinical parameters

ABSTRACT

Objective

To analyze the cervical range of motion (CROM) and clinical parameters in patients affected by myogenous temporomandibular disorders (TMD), cervicogenic dizziness (CGD), both TMD and CGD (TMD/CGD), and a group of healthy subjects (HS).

Methods

CROM degrees, Dizziness Handicap Inventory (DHI), Tampa Scale for Kinesiophobia (TSK-17), Hospital Anxiety and Depression Scale (HADS), and Jaw Functional Limitation Scale 20 (JFLS-20) scores were compared between 46 TMD patients, 49 CGD subjects, 43 TMD/CGD patients, and 98 HS.

Results

TMD/CGD and CGD patients demonstrated significantly lower CROM degrees and higher DHI, TSK-17, and HADS values when compared to TMD patients. TMD/CGD and TMD patients demonstrated higher JFLS-20 values when compared to CGD and HS. Significant negative correlations were found in TMD/CGD and TMD patients between JFLS-20 and CROM in flexion and extension.

Discussion

Present findings demonstrated a relation between spine movement impairment and TMD.
