Long Latency Reflex of Median Nerve among Healthy Adult Female Volunteers

Abstract

The present study was undertaken to record normal value of median nerve Long Latency Reflexes (LLR) from Abductor pollicis Brevis (APB) of dominant hand among females. LLR is a transcortical reflex loop obtained on submaximal stimulation of a mixed nerve. LLR can be used to diagnose individuals with proximal nerve lesions and S1 radiculopathy in the clinic. Normal values of late responses like the H-reflex and F-wave in the upper limb have been recorded in studies. The current observational study included 30 female participants aged 20 to 30 years old. The females who took part in the study were recruited in the early stages of their follicular development. By stimulating the median nerve while abducting the thumb, LLR was observed. The findings of this study revealed that Mean \(\pm\) SD for APB LLR latency was 46.29 \(\pm\) 2.58 milliseconds (ms). Mean \(\pm\) SD for APB LLR amplitude was 208.21 \(\pm\) 58.45 microvolt (\(\mu\)V). As a result, the normal values of LLR latency and Abductor Pollicis amplitude Brevis of the dominant hand in healthy adult female volunteers aids in the diagnosis of neurological diseases.
