The Impact of Cervical Sagittal Slope on Postural Oscillation and Balance
Abstract
Aim: Static balance and postural oscillation can be affected by different diseases. The aim of this study was to investigate balance disorders with clinical tests and stabilometric measurements in individuals with cervical lordosis loss or cervical kyphosis and to compare the balance state with cervical lordosis individuals.
Material and method: In our study, 102 patients, with cervical lateral radiographs and met criteria for inclusion into the study, who applied to the physical medicine and rehabilitation polyclinic within the last 6 months were evaluated. Patients were divided into 4 groups according to the cervical sagittal slope angles calculated based on the Cobb method. Stabilometric measurements of the patients were performed in 8 different positions (Table 1). In addition, the berg balance scale (BBS) and the activity-specific balance confidence scale (ABC) scores were calculated and the timed up and go test (TUG), the four square step test (FSST) and the functional reach test (FRT) were performed. Statistical significance was accepted as p <0,05 in all statistical evaluations.
Findings: Statistically significant differences were found in the head neutral position (NC) mediolateral oscillation rate, NC mediolateral total oscillation amount, NC anteroposterior oscillation rate, NC anteroposterior total oscillation amount, NC vectorial maximum oscillation amount, NC vectorial total oscillation amount, head in right rotation (HR) anteroposterior maximum oscillation amount, HR anteroposterior oscillation rate, HR anteroposterior total oscillation amount and eyes closed on sponge, head in neutral position (PC) anteroposterior maximum oscillation amount from the stabilometric measurements of the patients participating in the study. There was no significant difference between the groups in terms of BBS score, ABC score, TUG and FSST score and FRT.
Conclusion: According to the results of this study, while there were significant differences in terms of some posturographic parameters among the patients grouped according to the cervical sagittal slope angles, there was no difference between the groups in terms of some parameters. This result suggests that cervical sagittal slope gradually affects some components of postural performance from lordosis to kyphosis, however, not all components were affected by that.
