There have been significant technical improvements in recent decades that are under\u2010used in both routine practice and research. In current practice, disciplined techniques in acquisition and analysis of signals are required to appropriately define them. As an example, we describe such an exercise in acquisition and analysis. During a routine study, atypical spontaneous activity was encountered. High\u2010quality digital recordings were stored for off\u2010line analysis. These revealed waveforms that could be isolated and quantitatively defined using basic instrumentation available on most modern EMG systems: \u201cslow\u201d firing fibrillation potentials and a repeating fasciculation potential. Subjective analysis alone could not have identified them. To improve accuracy in identification and understanding of these waveforms, we propose criteria for data collection and signal analysis. This is critical for quality in routine practice, education, and proper reporting of electrophysiological signals.<\/jats:p>","DOI":"10.1002\/mus.27199","type":"journal-article","created":{"date-parts":[[2021,2,10]],"date-time":"2021-02-10T07:58:50Z","timestamp":1612943930000},"page":"657-660","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Atypical fibrillation and fasciculation potentials: An exercise in waveform identification and analysis"],"prefix":"10.1002","volume":"63","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8268-8643","authenticated-orcid":false,"given":"Paul E.","family":"Barkhaus","sequence":"first","affiliation":[{"name":"Medical College of Wisconsin  Milwaukee Wisconsin USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sanjeev D.","family":"Nandedkar","sequence":"additional","affiliation":[{"name":"Medical College of Wisconsin  Milwaukee Wisconsin USA"},{"name":"Natus Medical Inc  Hopewell Junction New York USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2021,2,26]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1037\/a0015701"},{"issue":"8","key":"e_1_2_7_3_1","first-page":"G12","article-title":"AAEE glossary of terms in neuromuscular and electrodiagnostic medicine","volume":"10","author":"AAEE Nomenclature Committee","year":"1987","journal-title":"Muscle Nerve"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/mus.26868"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/0013-4694(69)90217-X"},{"key":"e_1_2_7_6_1","first-page":"143","volume-title":"Recommendations for the Practice of Clinical Neurophysiology","author":"International Federation of Societies for Electroencephalography and Clinical Neurophysiology","year":"1983"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.clinph.2019.05.008"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1002\/mus.20638"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1002\/mus.24182"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1097-4598(200006)23:6<888::AID-MUS7>3.0.CO;2-B"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1002\/mus.23636"},{"key":"e_1_2_7_12_1","unstructured":"BarkhausPE NandedkarSD.
