To find out the influence of disc herniation at L5-S1 level on, H-reflex latency and H/M ratio.
Electrodiagnosis machine, Plinth, Measuring tape, ECGgel.
It is experimental study of same subject design. The study was conducted with 18 patients with disc herniation presented with unilateral radiating pain having positive SLR between age group of 20–50 yrs.
H-reflex recording was performed on subjects after positioning of the patient and electrodes, recording was done after a submaximal stimulus was given for H-reflex to posterior tibial nerve of affected and unaffected leg respectively.
Paired t-test was used for data analysis, which showed significant changes in H -latency (p<.05) and H/M ratio(p<.05) on affected side.
This study concluded that there are significant changes in H latency and H/M ratio on affected side. Hence H–reflex latency and H/M ratio can be used as diagnostic tool in L5-S1 level disc herniation.
