Effect of hand dominance on late responses in young adults


Author(s): Jimshad TU, Subin Solomen, Pravin Aaron, Anil T John

Abstract: Background: Late responses are the potentials appearing after motor response (M-wave) following mixed nerve stimulation. There are 2 important late responses H-reflex and F-response. In past decades, several researchers reported differences in electro physiological properties between dominant and non-dominant upper extremities. Objective of the study was to find out the effect of hand dominance on the H reflex latency and amplitude and to find out the effect of hand dominance on the F wave latency and FM ratio.rnMethods and Material: Healthy subjects of either gender between the age group of 17-25 years and with BMI of 18-23 were included. Subjects divided in to two groups, 15 right handed and 15 left handed and late responses study were conducted to find out the effect of hand dominance on H-reflex and F-wave parameter.rnResults: H-reflex latency of dominant group, dominant was 23.40 and non-dominant hand was 24.31 which was statistically significant (p<.0001). Also H-reflex amplitude dominant hand was 0.89 and non-dominant hand was 0.67 which was statistically significant (p<.0001) F-wave latency of dominant group, dominant hand was 23.24 and non-dominant hand was 24.50 which was statistically significant (p<.0001).Also F-M ratio of dominant hand was 21.22 and non-dominant hand was 22 .68 which was statistically significant (p<.0001).rnConclusions: Results suggest that Hand dominance has an significant effect on the H-reflex latency and amplitude and also significant effect on F-wave latency and F-M ratio.
