People with Chronic Musculoskeletal Pain shows Altered Left/Right Judgement Task

The patients with chronic musculoskeletal pain experienced altered motor imagery performance, findings from a recent investigation conducted by John D.Breckenridge and colleagues.

Poor accuracy is believed to reflect disrupted cortical proprioceptive representations or body schema and abnormally long response times are believed to reveal delayed processing of body/spatial representations. Various clinical studies have reported slower and less accurate responses on the left/right judgement task (LRJT) in a variety of chronic musculoskeletal pain conditions. However, no systematic analysis has been carried out to estimate if the altered motor imagery performance determined via LRJT is the characteristic of all chronic musculoskeletal pain conditions or not.

A total of 25 studies involving 2266 patients who went through LRJT were involved. Eight electronic databases from beginning to March 2017 were searched for these studies. As per analysis, the limb and face related chronic musculoskeletal pain states were found to be significantly related with altered motor imagery performance as determined via LRJT.

Although, these pieces of evidence exclusively govern altered motor imagery performance in peripheral pain states and for axial pain conditions, very less evidence was present.
