The Effect of F-response Parameters in ALS and Polio Patients

Abstract

In this study, 300 signal records were acquired in each session using surface electrode under submaximal stimulation. Data set were formed from 10 ALS and Polio patients with 10 normal individuals. The muscle group under study was abductor pollisis brevis and abductor digiti minimi muscles which were interconnected to median and ulnar nerves. Parameters were calculated by doing F-response analysis to the acquired recordings. The most prominent parameters among the calculated ones are mean sMUP amplitude and MUNE value. Mean sMUP amplitude value can differentiate patients from normal individuals in both muscles. Moreover, the MUNE value that are calculated from abductor pollisis brevis muscle can differentiate all groups from each other significantly (p<0.05).
