Myogenic hypothesis
WebJun 8, 2015 · The metabolic hypothesis focuses on the balance between oxygen supply and demand rather than blood flow. Accumulation of metabolites such as H +, K +, adenosine or CO 2, during periods of poor supply and tissue hypoxia serve to produce vasodilation, thereby restoring blood flow. WebNov 28, 2024 · Vestibular evoked myogenic potential (VEMP) testing averages short latency myogenic responses evoked by sound that stimulates activation of the saccule or utricle, or both. 1,2 The US Food and Drug Administration approved VEMP in October 2015. Caloric testing assesses only horizontal semicircular canal vestibulo-ocular reflex function, and …

WebWe tested the hypothesis that older males (OMs, 70±4 yr, n=9) would have a blunted myogenic response to a physiological stimulus compared to younger controls (21±3 yr, n=9). Subjects completed an acute bout of intense unilateral muscle loading. Young healthy males matched for body mass and activity level served as the control group.
