Abstract
Purpose : To investigate the relationship between breathing pattern disorder and joint position error (JPE) in patients with chronic low back pain (CLBP).

Methods : Thirty nine patients with CLBP participated. End-tidal CO2 and respiration rate (RR) were measured using a capnography. Breathing hold time (BHT) and Nijmegen Questionnaire (NQ) were investigated. Thoracic excursion was measured with a cloth tape measurement technique. Joint position error were measured using a small laser point mounted on a lightweight headband. they were asked to relocate the head, after the neck movement on the horizontal plane. Pearson 's test was used for correlation analysis between respiratory variables and JPE in patients with CLBP. Independent t-test was used to verify the difference between thoracic and diaphragm breathing pattern in patients with CLBP. The significance level was set at 0.05.

Results : There was a significant correlation between JPE (LR) and JPE (RR, EX) (r = .639, r = .813) (p <.001) and a low negative correlation with end-tidal CO2 (r = -.357) (p <.05). There was a significant correlation between RR and JPE (EX) (r = .750) (p <.001). There was a low correlation between JPE (EX) and NQ (r = .333) (p <.05). There was a somewhat higher negative correlation between NQ and thoracic excursion (r = -.528) (p <.001). There was a somewhat higher negative correlation between thoracic excursion and JPE (LR ,RR, EX) (r = -.470, r = -.484, r = -.602) (p <.001). There were no significant differences in the RR, BHT, NQ, and thoracic excursion between the thoracic and diaphragmatic breathing (p >.05). There was a significant difference in the JPE (EX), end - tidal CO2, and VAS values between the thoracic and diaphragm breathing (p <.05).

Conclusion : There was a correlation between JPE (EX) and NQ in patients with CLBP, and correlation between thoracic excursion and JPE (LR, RR, EX) and NQ. There was a significant difference in the JPE (EX), end-tidal CO2 level, and VAS value in the comparison of thoracic breathing and diaphragm breathing. The results showed that breathing patterns and JPE were related to each other.
