The Unchanging Latency of Transcranial Motor Evoked Potentials amongst
various Age Groups
Abstract
Human growth and development entail dynamic changes in bodily
dimensions, yet motor proficiency seems to remain consistent over time.
This study examines the latency of Transcranial Motor Evoked Potentials
(TcMEPs) across various age groups to assess whether motor velocity
adjustments are necessary with age. Data were collected from 100
patients undergoing surgery with intraoperative neuromonitoring at the
All India Institute of Medical Sciences, New Delhi, between January 1,
2019, and January 1, 2020. TcMEP recordings were analysed for seven
commonly monitored muscles across seven age groups: <10 years,
10-19 years, 20-29 years, 30-39 years, 40-49 years, 50-59 years, and
>60 years. The study found no significant differences in MEP
latency with age, suggesting that motor response latency remains stable
despite variations in bodily dimensions across different age groups.
These results contribute to understanding motor proficiency and its
stability over the human lifespan.
