The most common posture is flexion and ulnar deviation of the wrist, and a tight grip of the pen with the thumb and index finger. The first line of treatment is botulinum toxin injection into target muscles which are thought to be overactive.Botulinum ToxinBotulinum ToxinSpringer Berlin ...
The direct effect of a modified pen grip between the proximal phalanges of index and middle finger was studied in 23 patients with writer's cramp by Baur et al. [41] They reported that the change of pen grip did not influence kinematic writing aspects but caused an immediate reduction of ...
10 patients with writer's cramp and 10 healthy controls, we applied focal TMS over each primary motor area and recorded motor evoked potentials (MEPs) from contralateral hand and arm muscles while participants imagined a tonic abduction of the index finger contralateral to the stimulated hemisphere....

The objective of this study was to examine phase- and task-dependent modulation of stretch reflexes during repetitive finger movements in writer's cramp, and compare them with normal controls from our previous study. A subject with writer's cramp conducted two rhythmic tasks, index finger ...
processing of simultaneous sensory information in adult humans with writer's cramp, we used functional magnetic resonance imaging to compare the response in primary sensory cortex with simultaneous tactile stimulation of the index and middle finger, with the response to stimulation of each finger alone...
Using fMRI, this study compared 31 right-handed writer's cramp patients to 35 controls in reward-based learning of a probabilistic reversal-learning task. All subjects chose between two stimuli and indicated their response with their left or right index finger. One stimulus response was rewarded ...
There were seven conditions, each repeated twice: rest, writing, tapping with index finger for 2, 3, 4, and 5 min. For each scan, we obtained EMG recordings from the flexor digitorum superficialis (FDS), extensor indicis proprius (EIP) muscles, and a subjective score of severity of ...
