To investigate whether proprioceptive accuracy measured with the Joint Position Sense (JPS) in patients with chronic neck and low back pain is impaired exclusively in affected areas or also in distant areas, not affected by pain.
Cross-sectional study.
Interdisciplinary outpatient rehabilitation clinic for back and neck pain.
Patients with chronic neck pain (n=30), patients with chronic low back pain (n=30) and age- and sex-matched asymptomatic control subjects (n=30).
Not applicable.
Patients and asymptomatic control subjects completed a test procedure for the JPS of the cervical spine, lumbar spine and ankle in a randomized order. Between group differences were analyzed with the univariate analysis of variance and associations of the JPS with clinical features using the Pearson’s correlation coefficient.
Both patients with chronic neck pain (p < 0.001) and patients with chronic low back pain (p 0.05). An association of the JPS with clinical characteristics, however, could not be shown.
These results suggest widespread impairment of proprioceptive accuracy in patients with chronic and low back pain and a role for central sensorimotor processes in musculoskeletal pain conditions.
