The effect of rTMS over the cerebellum in normal human volunteers on peg-board movement performance.
نویسندگان
چکیده
Low frequency rTMS over the paramedian part of the right cerebellum was used to test the effects of TMS-induced disruption of the cerebellum on performance of the 10-hole pegboard task. A test group (n = 14) showed significantly increased movement times lasting about 3 min after the 5-min 1 Hz rTMS train, compared to a control group who received no rTMS (n = 14), tested in a parallel group design. The increase was greatest for the hand ipsilateral to the stimulation, but the difference between the two hands was not statistically significant. These results suggest that the rTMS affects cerebellar excitability and cause a short-lasting bilateral change in sensory-motor performance.

Comparison of effects of transcranial magnetic stimulation on primary motor cortex and supplementary motor area in motor skill learning (randomized, cross over study)
Motor skills require quick visuomotor reaction time, fast movement time, and accurate performance. Primary motor cortex (M1) and supplementary motor area (SMA) are closely related in learning motor skills. Also, it is well known that high frequency repeated transcranial magnetic stimulation (rTMS) on these sites has a facilitating effect. The aim of this study was to compare the effects of high...
متن کاملRole of the cerebellum in externally paced rhythmic finger movements.
Several studies have suggested that the cerebellum has an important role in timing of subsecond intervals. Previous studies using transcranial magnetic stimulation (TMS) to test this hypothesis directly have produced inconsistent results. Here we used 1-Hz repetitive TMS (rTMS) for 10 min over the right or left cerebellar hemisphere to interfere transiently with cerebellar processing to assess ...
متن کاملHigh-frequency repetitive transcranial magnetic stimulation to the cerebellum and implicit processing of happy facial expressions.
BACKGROUND Previous research has demonstrated that the cerebellum is involved in emotive and cognitive processes. Furthermore, recent findings suggest high-frequency repetitive transcranial magnetic stimulation (rTMS) to the cerebellum has mood-improving properties. We sought to further explore the effects of cerebellar high-frequency rTMS on implicit processing of emotional stimuli and mood. ...

Objectives: Stroke is the leading cause of long-term disability. Hand motor impairment resulting from chronic stroke may have extensive physical, psychological, financial, and social implications despite available rehabilitative treatments. The best time to start treatment for stroke, is in sub-acute period. Repetitive transcranial magnetic stimulation (rTMS) is a method of stimulating and ...
