Investigating the effect of real-time spinal postural biofeedback on seated discomfort in people with non-specific chronic low back pain
Chronic Low Back Pain (CLBP) is a large problem within the society. Prolonged sitting frequently aggravates CLBP. It appears that CLBP patients adopt a more dynamic sitting behavior resulting in using a large range of motion compared to the pain-free population. The aim of this study is to investigate how sitting behavior is related with seated LBP and whether the use of postural biofeedback can reduce LBP.
A total of 24 CLBP patients were analyzed during a 2-hour sit in which 16 patients developed LBP with an increase of at least two points on the NRS of pain. Those patients repeated the sitting task several days later while receiving postural biofeedback. During the second sitting task this group developed less increase of pain and sitting posture was less end-range and less variable. This study provides preliminary evidence that the use of biofeedback could be useful as one of the tools within the management of CLBP patients. > From: O’Sullivan et al., Ergonomics 56(8) (2013) 1315-25.
