Discharges of single motor units at voluntary contraction of abductor digiti minimi muscle in man.
Isometric tension in a muscle can be graded by varying the firing rate of each motor unit as well as by varying the number of units which are recruited. Several important reports have been published dealing with the relation between the tension produced in a muscle and firing rate of single motor units in voluntary contraction in human muscles 2-4. However, the question of how the firing rate c...
متن کاملMorphologic Aspects of Abductor digiti minimi Muscle in the Hand
It is cited at the anatomical literature that the Abductor digiti minimi muscle can be composed by one or more muscular beams (Williams et al., 1995; Murata et al., 2004), being more found presenting only one beam, as described by Testut (1911) and schematized in pictures by other authors (Grant, 1948; Testut & Latarjet, 1959; Gray, 1977; Lockhart et al., 1983; Woodburne, 1984). However, some a...
متن کاملAccessory Abductor Digiti Minimi - A Case Report
The accessory ADM is the most common anomaly among all the accessory hypothenar muscles , with a prevalence of 24%, and present bilaterally in 50% of the cases . During routine dissection of undergraduates we have come across the presence of this accessory muscle in the wrist when the carpal tunnel is opened. This presents with Abductor Digiti Minimi (ADM) muscle bilaterally , involving ulnar a...
متن کاملContractile properties of the abductor digiti minimi muscle in paramyotonia congenita.
In two subjects with paramyotonia congenita the isometric torque generated by the abductor digiti minimi and the surface EMG recorded over ADM decreased during prolonged or repetitive contractions, whether these were voluntarily or electrically induced. Isometric twitch times did not alter significantly during this muscle fatigue. Cooling greatly accelerated the fatiguing process. It is suggest...
متن کاملAbductor digiti minimi muscle flap transfer to prevent wound healing complications after ORIF of calcaneal fractures.
OBJECTIVES To examine the transfer of abductor digiti minimi (ADM) muscle flaps as a method for preventing wound healing complications in cases of closed calcaneal fractures treated with open reduction and internal fixation (ORIF). METHOD DESIGN Retrospective review. PATIENTS Twenty-six cases of acute closed calcaneal fracture in patients at risk for serious wound complications or with s...
