Disturbances of grip force behaviour in focal hand dystonia: evidence for a generalised impairment of sensory-motor integration?
BACKGROUND Focal task specific dystonia occurs preferentially during performance of a specific task. There may be an inefficiently high grip force when doing manipulative tasks other than the trigger task, possibly reflecting a generalised impairment of sensory-motor integration. OBJECTIVE To examine how well subjects with writer's cramp (n = 4) or musician's cramp (n = 5) adapted their grip ...
متن کاملMotor and Sensory Dysfunction in Musician’s Dystonia
Musicians' dystonia is a task-specific and painless loss of motor control in a previously well-executed task. It is increasingly recognized in the medical and musical community. Recent advances in neuroimaging, transcranial magnetic stimulation and novel techniques in electroencephalography have shed light on its underlying pathophysiology. To date, a deranged cortical plasticity leading to abn...
متن کاملAlteration in forward model prediction of sensory outcome of motor action in focal hand dystonia
Focal hand dystonia in musicians is a movement disorder affecting highly trained movements. Rather than being a pure motor disorder related to movement execution only, movement planning, error prediction, and sensorimotor integration are also impaired. Internal models (IMs), of which two types, forward and inverse models have been described and most likely processed in the cerebellum, are known...
متن کاملFocal dystonia and the Sensory-Motor Integrative Loop for Enacting (SMILE)
Performing accurate movements requires preparation, execution, and monitoring mechanisms. The first two are coded by the motor system, the latter by the sensory system. To provide an adaptive neural basis to overt behaviors, motor and sensory information has to be properly integrated in a reciprocal feedback loop. Abnormalities in this sensory-motor loop are involved in movement disorders such ...
متن کاملSensory motor retuning: a behavioral treatment for focal hand dystonia of pianists and guitarists.
OBJECTIVE To evaluate the long-term effectiveness of sensory motor retuning (SMR), a new treatment for focal hand dystonia in musicians. DESIGN Prospective case series with an (adventitious) comparison group with 3- to 25-month follow-up in piano and guitar and 0- to 4-month follow-up in flute and oboe players. SETTING General community in Germany. PARTICIPANTS Eleven professional musicia...
