Hand dominance and motor unit firing behavior.
Daily preferential use was shown to alter physiological and mechanical properties of skeletal muscle. This study was aimed at revealing differences in the control strategy of muscle pairs in humans who show a clear preference for one hand. We compared the motor unit (MU) recruitment and firing behavior in the first dorsal interosseous (FDI) muscle of both hands in eight male volunteers whose ha...
متن کاملREVIEW Motor Unit Firing Behavior in Man
Studies on motor unit firing behavior in man by the decomposition technique are described. The decomposition technique identifies motor unit firing with 100% accuracy at force levels of greater than 80% maximal voluntary contraction (MVC). In all muscles examined, the higher the recruitment threshold of the motor unit, the lower the rate at which it fired at the target level. Smaller muscles, s...
متن کاملLateral dominance and motor unit firing behavior.
Twelve subjects were classified as left-handed (LH) or right-handed (RH) using Annett's hand dominance classification. Motor unit recordings were obtained from the first dorsal interosseous (FDI) muscle of each hand using a quadrifilar needle electrode. Firing occurrences of individual motor units were then identified and the firing rates of all motor units recorded during the contraction were ...
متن کاملSynchronization of motor unit firings: an epiphenomenon of firing rate characteristics not common inputs.
Synchronous motor unit firing instances have been attributed to anatomical inputs shared by motoneurons. Yet, there is a lack of empirical evidence confirming the notion that common inputs elicit synchronization under voluntary conditions. We tested this notion by measuring synchronization between motor unit action potential trains (MUAPTs) as their firing rates progressed within a contraction ...
متن کاملSynchronization of Motor Unit Firings : 1 An Epiphenomenon of Firing Rate Characteristics not Common Inputs
25 Synchronous motor unit firing instances have been attributed to anatomical inputs shared 26 by motoneurons. Yet, there is a lack of empirical evidence confirming the notion that common 27 inputs elicit synchronization under voluntary conditions. We tested this notion by measuring 28 synchronization between motor unit action potential trains (MUAPTs) as their firing rates 29 progressed from a...
