Abstract
Background: Low back pain (LBP) is common in nurses, but it is unclear if the pain is associated with measurements of postural control. Objective measurements of function might be useful in the evaluation of patients with LBP in order to evaluate and predict disability, and in the study of the pathophysiology of chronic LBP. Methods: In a cross-sectional study, we measured the number of postural adjustments, and degree of posterior-lateral sway in 81 nurses, using a computerized postural sway four-platter measurement system. Results: There were 41 (56.6%) nurses who complained of LBP at the time of testing, and another 12 (14.8%) with a past history of LBP. Nurses with LBP consistently used more postural adjustments to keep their balance (p < 0.003), and in some positions postural adjustments were positively associated with the degree of past and present pain. LBP was not significantly associated with the degree of lateral sway. Conclusions: Nurses either with present or a past history of LBP use an increased number of postural adjustments to maintain balance. Studies are warranted to determine if postural testing can predict the development of LBP or aid in determining appropriate preventive measures.
