There were insignificant differences between the three groups before intervention and significant statically differences of pain and function and electrophysiological parameters at 6 months post intervention by comparing both first and second groups with the third group while the first and second groups were comparable
LSD least significant difference = mean, SD standard deviation, 0=at baseline, 6= at 6 months post-intervention. VAS Visual Analogue Scale
