Effect of dominancy on H-reflex and F-wave and formulating dominancy corrective formula

Effect of Dominancy on MNCV and SNCV is well known but its effect on late responses i.e. H-reflex and F-wave has not been studied yet. In this study correlation between H-reflex of tibial nerve and F-wave of median nerve in dominant and non-dominant lower limb and upper limb was studied in 30 female subjects in age group between 19–25 years. Their dominancy was assessed by Edinburgh Handedness for upper limb and by Waterloo footedness questionnaire for lower limb. From the t-paired test t value is 0.870 for F-latency,

0.070 for F-velocity, 2.241 for H-latency and 0.438 for H/M and the correlation describes the correlation between right and left F-latency, right and left H-latency. It was concluded that there are no significant changes between F-wave and Hreflex in dominant and non-dominant upper limbs and lower limbs and there are no significant relationship between Fwave and H-reflex in dominant and non-dominant upper limbs and lower limbs. The formula for Dominancy corrective factor for F-latency is created by using the mean values of right and left F-latencies.
