OBJECTIVE: To investigate the distribution of segmental flexion mobility in the cervico-thoracic spine of men and women with whiplash-associated disorders. The study also assesses the relationship between cervical mobility and segmental flexion mobility, and whether hypomobility in C7-T1 is associated with neck pain and weakness in the hands. Finally, the study investigates the impact of fear of movement/(re)injury and pain intensity on cervical mobility. METHOD: The data in this longitudinal study was obtained from a previous trial on 47 patients. Assessments were performed at baseline and 3 and 9 months following randomization using a cervical range of motion instrument, the cervico-thoracic ratio, a Grippit, a visual analogue scale, a Painmatcher, and the Tampa Scale for Kinesiophobia. RESULTS: Women exhibited hypomobility in C7-T1. There was no significant association between the 2 cervical measurement techniques. The correlation between flexion mobility in C7-T1 and grip strength was weak but significant (r=-0.3) (p<0.05). There was also a weak but significant negative correlation between total cervical mobility and neck pain intensity. No significant correlation was found between fear of movement/(re)injury and cervical mobility. CONCLUSION: Women with whiplash-associated disorders seem to exhibit flexion hypomobility in C7-T1. The flexion mobility in C7-T1 was weakly, but significantly, correlated with grip strength, but was not shown to predict neck pain. Neck pain may give rise to restricted range of motion.Downloads
