Phenotype details |
Voluntary EMG - abnormal bilateral EMG activity during unilateral contraction of APB muscle. Focal TMS - abnormal bilateral motor evoked potentials in the thenar muscle following unilateral stimulation of the motor cortex. Shorter cortical silent period following unilateral M1 stimulation; lengthening of cortical silent period following bilateral M1 stimulation. During intended unilateral contraction, dissocciation of task-related short-interval intracortical inhibition modulation between task and mirror APB. F waves - normal ipsilateral F waves evoked from unilateral median nerve stimulation. SEP - normal, lateralized latencies of the N20 and P25 parietal components of the median nerve somatosensory evoked potentials. LLR - normal ipsilateral V1 but abnormal bilateral V2 long-latency EMG responses recorded in both thenar muscles.
Frequency of ipsilateral MEPs = 100%. Relative amplitude (MEPipsi/MEPcontra) = 47%. Latency of contralateral MEPs (ms) = 21,9. Latency of ipsilateral MEPs (ms) = 22,5. |
