Effect of Combined Lumbar Traction and Repetitive Back Extension Exercise on H-reflex in Lumbosacral Radiculopathy

Repeated back extension exercises as described by McKenzie from prone position has been widely suggested for patients with lumbosacral radiculopathy (LSR). It has been reported to decrease radicular symptoms which could be due to the decompression effect of this exercise on the compromised nerve root. Moreover, mechanical traction have a debatable effect on lumbosacral patients with little evidence that supports its effectiveness. Thus, the investigators hypothesize that performing a combination of lumbar traction and repeated back extension exercise will improve the soleus H-reflex, pain, and function of lumbosacral radiculopathy patients.
