Abstract We studied the relationship between muscle activity (electromyography, EMG), force, and brain during isometric contractions of index finger, on a group individual level. Ten subjects contracted their right or left finger at 5, 15, 30, 50, 70% maximal force. Subjects received visual feedback produced focused our analysis activation that correlated with EMG. Brain specific anatomical areas (region‐of‐interest analysis, ROI) was quantified EMG activity. Furthermore, we tried to...
In humans, hand performance has evolved from a crude multidigit grasp to skilled individuated finger movements. However, control of the fingers is not completely independent. Although musculotendinous factors can limit independent movements, constraints in supraspinal are more important. Most previous studies examined either flexion or extension digits. We studied differences voluntary force production by five digits, both and tasks. Eleven healthy subjects were instructed maximally flex...
<i>Background:</i> Plasma prolactin levels are sensitive to dopamine and serotonin function, fatigue. Low cortisol, and/or may be involved in burnout detachment. <i>Methods:</i> In this double-blind within-subject study, we treated 9 female subjects controls with 35 mg cortisol placebo orally. We measured state affect plasma prolactin, oxytocin, adrenocorticotropic hormone levels, administered an attachment questionnaire. <i>Results:</i> The displayed...
While the human hand has an extraordinary capacity to manipulate objects, movement of its digits is usually not completely independent. These limits have been documented for extrinsic flexor muscles, although skills also require selectivity extension movements. Hence, we measured degree independent control major extensor (extensor digitorum, ED). Subjects grasped a cylinder, with thumb perpendicular fingers. Load cells were connected proximal phalanges fingers and thumb's distal phalanx....
