Clinical Trial Summary

Diagnostic and prognostic value of pain hypersensitivity in low back pain (LBP) is not fully understood.Increased pain sensitivity in the primary area of pain (local pain) is considered a sign of predominantly peripheral pain sensitization,value of pain hypersensitivity in low back pain (LBP)is not fully understood whereas pain sensitivity in distal and remote areas is considered to present a more central phenomenon. It is suggested that pat ents with enhanced pain sensitivity report high level of disability. Despite fact that pain and disability are associated in chronic LBP the exact mechanisms of sensitivity contribution in LBP disability is unknown. It has also been suggested that muscle function changes may be driven by pain. The possible role and contribution of trunk muscles function to pain and disability phenomena remain unknown.

This study was aimed to estimate prevalence and possible correlation among pain hypersensitivity and functional and electromyography parameters of trunk muscles in patients reporting early phase of chronic LBP.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Pain hypersensitivity parameters: pain threshold and pressure pain tolerance threshold will be measured by pressure algometer pressure was applied using a probe with an area of 1 cm2 and intensity to a maximum of 1,000 kPa at a rate of 30 kPa/s.	pain detection threshold and pressure pain tolerance threshold (PPTT) )will be measured at the site of maximal pain and of more distant nonpainful point at the back, and the ipsilateral great toe 3 times and average value will be taken for statistics analyses	up to 3 months
