Clinical assessment versus biomechanical assessment in participants whith mild cervical disability according to the Vernon index in secretariats
Main Article Content
Abstract
The purpose of the research was to evaluate the correlations between the clinical and biomechanical evaluations of the cervical spine in secretaries without cervical disability versus secretaries with mild cervical disability according to the cervical disability index (Vernon). It presented a quasi-experimental, longitudinal design, the sample was made up of secretaries of the University of Talca, they were chosen according to the inclusion criteria: women, age 20-65 years, secretaries of the University of Talca and exclusion criteria: congenital abnormalities, history of severe trauma and/or fracture in the cervical spine, spinal surgeries and cardiovascular pathologies. The 20 secretaries were divided into two groups according to the Vernon cervical disability index: mild cervical disability and no disability. Biomechanical evaluations (surface electromyography and kinematic analysis of the cervical spine) and clinical evaluations (VAS pain and cervical disability index) were performed. The clinical evaluations (VAS pain and Vernon cervical disability index) achieved statistically significant differences (p < 0.05) between groups, therefore, they are discriminative variables in the clinical evaluation of the cervical spine, and they manage to be a tool effective for the evaluation of patients suffering from mild neck pain. There is a statistically significant strong correlation between the intergroup and intragroup biomechanical variables, but they were not sensitive to differentiate the relatively similar groups (without cervical disability vs. mild cervical disability). The clinical evaluations were more sensitive to show statistically significant differences of the relatively similar groups.
