This study was performed in military subjects with chronic non-specific low back pain (CNSLBP,
Groups displayed a similar ability to discriminate between different levels of movement scaling. Still, subjects with CNSLBP showed an abnormal performance and tended to overestimate their own movements (shifted psychophysical curve).
These results extend previous work in patients with CNSLBP, and denote an important relationship between body perception, movement and pain. As such, the method developed in this study can offer new avenues for understanding and managing body perception disturbances and abnormal movement patterns in patients with pain. A similar method is currently being implemented for the assessment of perception of upper limb movements in individuals with complex regional pain syndrome. It could also potentially be extended to therapeutic applications, to help patients with kinesiophobia to overcome their fear of moving.
