'''Electromyography''' ('''EMG''') is a technique for evaluating and recording the electrical activity produced by [[skeletal muscles]].<ref name="Robertson">{{Cite book|last1=Robertson|first1=D. G.

An electromyograph detects the [[electric potential]] generated by muscle [[cell (biology)|cell]]s<ref>{{MeshName|Electromyography}}.</ref> when these cells are electrically or neurologically activated. The signals can be analyzed to detect abnormalities, activation level, or recruitment order, or to analyze the [[biomechanics]] of human or animal movement. Needle EMG is an [[electrodiagnostic medicine]] technique commonly used by neurologists. Surface EMG is a non-medical procedure used to assess muscle activation by several professionals, including physiotherapists, kinesiologists and biomedical engineers. In computer science, EMG is also used as middleware in [[gesture recognition]] towards allowing the input of physical action to a computer as a form of [[human-computer interaction]].<ref>{{cite journal | last1=Kobylarz | first1=Jhonatan | last2=Bird | first2=Jordan J. | last3=Faria | first3=Diego R. | last4=Ribeiro | first4=Eduardo Parente | last5=Ekárt | first5=Anikó | title=Thumbs up, thumbs down: non-verbal human-robot interaction through real-time EMG classification via inductive and supervised transductive transfer learning | journal=Journal of Ambient Intelligence and Humanized Computing | publisher=Springer Science and Business Media LLC | date=2020-03-07 | volume=11 | issue=12 | pages=6021–6031 | issn=1868-5137 | doi=10.1007/s12652-020-01852-z | doi-access=free }}</ref>
