Writers Cramp in Office Workers—an Epidemiologic and Psychosomatic Study
The study is aimed at investigating the occurrence of writers cramp in office workers, drawn from ten major offices of Kanpur to determine the nature and relationship of various emotional factors in the development of this disability. The observations on writers cramp cases were compared with a group of normal and diseased controls. Out of a surveyed population of 3,325 office workers, there we...
متن کاملKinematic Assessment Force of Writer’s Cramp Before And During Cramp
In this paper, kinematic characteristics of writing are compared in 5 patient with writer’s cramp who performed a set of standardized writing task. The kinematic characteristics thumb and forefinger force before and during cramp. The effect of writing on different inclined supporting surfaces is also investigated. Our results indicate that inclined surfaces aspects of writing discomfort in writ...
متن کاملAberrant Sensorimotor Integration in Musicians’ Cramp Patients
Simple tapping and complex movements (Luria finger apposition task) were performed unimanually and bimanually by two groups of professional guitarists while EEG was recorded from electrodes over the sensorimotor cortex. One group had a task-specific movement disorder (focal dystonia or musicians’ cramp), while the other group did not (controls). There were no significant group interactions in t...
متن کاملTask requirements influence sensory integration during grasping in humans.
The sensorimotor transformations necessary for generating appropriate motor commands depend on both current and previously acquired sensory information. To investigate the relative impact (or weighting) of visual and haptic information about object size during grasping movements, we let normal subjects perform a task in which, unbeknownst to the subjects, the object seen (visual object) and the...
متن کاملHallucis Muscle During Cramp Contractions
33 We analyzed individual motor units during electrically-elicited cramp contractions with 34 the aim of characterizing the variability and degree of common oscillations in their discharges. 35 Intramuscular and surface EMG signals were detected from the abductor hallucis muscle of 11 36 healthy subjects (age 27.0 ± 3.7 yrs) during electrically-elicited cramps. In total, 48 motor units 37 were ...
