Mechanisms of Arthrogenic Muscle Inhibition

Adam S. Lepley and Lindsey K. Lepley

directly interferes with muscle strength recovery as patients are often unable to neurologically engage (eg, fully contact) their muscle during exercise. 6 This diminished ability to fully contract the musculature surrounding an injured joint, termed arthrogenic muscle inhibition (AMI), is a common

Associations of Device-Measured Physical Activity, Sedentary Behavior, and Executive Function in Preadolescents: A Latent Profile Approach

intervention on EF ( 36 ). A meta-review showed no effect of classroom PA intervention on EF in school-aged children ( 46 ). Inconsistency also exists across multiple measures for the specific domain of EF. For example, several reviews reported a small to moderate effect of PA intervention on inhibition ( 1

Effects of Acute Physical Exercise With Low and High Cognitive Demands on Executive Functions in Children: A Systematic Review

monitoring of complex, goal-directed processes involved in perception, memory, and action ( 10 , 13 ). The 3 interrelated and interacting core domains of EF are inhibition, working memory, and cognitive flexibility ( 9 , 10 ). In this context, inhibition describes a deliberate suppression of distracting

The Relationship Between Physical Activity and Inhibition in Children With and Without Motor Impairments

Attentional and Motor Response Priming in a Bimanual Task

Steve Hansen, James L. Lyons, and Katherine M. Keetch

This study examined the performance of the upper limbs during responses to previously cued and un-cued locations. Participants made unimanual and bimanual responses under homologous and non-homologous muscular control, within a cuetarget (Experiment 1; n = 10), and a target-target (Experiment 2; n = 10) aiming protocol. The inhibition of return (IOR) to a target location was expected to increase with (a) an increase in the organization of the movement response required, and (b) the decrease in the muscular coupling under which the bimanual movement was performed. IOR was observed in both experiments when participants completed their movements in either the unimanual or homologous conditions, but not in the non-homologous condition. In addition, reaction times were significantly shorter when a movement preceded the response than when no manual response was made to the initial visual cue. The results indicate that common processing delays in response to exogenously cued targets are dependent on the muscular control of those responses. Thus, this study provides evidence that IOR is moderated by the muscular control under which the bimanual movement was performed indicating an influential involvement of the motor system in both the movement planning and movement response to multiple target stimuli.

Arthrogenic Muscle Inhibition: Best Evidence, Mechanisms, and Theory for Treating the Unseen in Clinical Rehabilitation

Grant Norte, Justin Rush, and David Sherman

, there appears to be a “disconnect” between what they want to do and what they can do. This common clinical scenario reflects an underlying neurophysiological phenomenon known as arthrogenic muscle inhibition (AMI) in which otherwise healthy muscle becomes reflexively inhibited following an injury to
