INSTRUMENTATION & TECHNIQUES Reinventing the algometer: Synopsis of the literature and presentation of a reliable, inexpensive model

摘要: This article summarizes the historical development ofthe algometerirtscirntiflcinvestigations and notes hallmarks in evolution of device. The algometer has served as a safe nociceptive stimulus for more than century. Although earliest renditions were inexpensive, they often unreliable difficult to operate. More modern versions have brought reliability, but at increased expense complexity. Newer failed make device easy enough use be practical. “reinvented” is reliable, less expensive commercial devices, build use. These improvements should allow greater application empirical research assessment pain. problems creating easy, technique producing pain experimental purposes are evidenced by 80 methodologies presented literature since 1943 (see Goetzl, Burrill, & Ivy, 1943). Myriad attempts produce workable typically involved stimulation chemical, electrical, thermal, or mechanical nature. An instrument that applies pressure assess commonly referred algometer, although it sometimes called “Catteli’s Algometer” (Head Holmes, 1911). According Keele (1954), “this well established [was] used far back Victorian days” (p. 636) best meets need simple appears nonnoxious subject possible. synopsis looks ways been utilized exploration psychophysical mechanisms perception. discussion algometry will limited devices involving cutaneous deep somatic pressure.
