BALANCE PERFORMANCE IN DUAL TASK IN PATIENTS WITH CERVICAL DISC HERNIATION RELATED CHRONIC NECK PAIN: A COMPARATIVE STUDY

Purpose: The aim of the study was to compare balance performance in dual task between patients with cervical disc herniation (CDH) related chronic neck pain and asymptomatic controls. Methods: Thirty-two patients with CDH related chronic neck pain and twenty-three age and sex-matched asymptomatic controls participated in this cross-sectional controlled study. The modified clinical test of sensory integration of balance (mCTSIB), athletic single leg test (ASLT), limits of stability (LOS), and fall risk assessment were performed with and without a cognitive task. Dual task interference (DTI) was assessed. Results: According to our findings, the change in the mCTSIB values (except standing with eyes closed on a firm surface) and fall risk scores was greater in the CDH group compared to the control group (p<0.05). Additionally, the DTI of the mCTSIB values (except standing with eyes closed on a firm surface) and fall risk scores were higher in the CDH group than in the control group (p < 0.05). Conclusions: The results of study suggest that patients with CDH related chronic neck pain have poorer postural control and increased fall risk under dual task conditions. Patients with CDH related chronic neck pain should participate in rehabilitation program to increase balance and postural control.
