Bestemmelse af stimuleringsniveauer til transkraniel magnetisk stimulering

Induced movement in a patient (40) is detected and correlated with a TMS stimulating pulse so as to determine the patient's motor threshold stimulation level. Direct visual or audible feedback is provided to the operator (10) indicating that a valid stimulation has occurred so that the operator (10) may adjust the stimulation accordingly. A search algorithm (50) may be used to direct a convergence to the motor threshold stimulation level with or without operator intervention. A motion detector (60) is used or, alternatively, the motion detector (60) is replaced with a direct motor evoked potential (MEP) measurement device that measures induced neurological voltage and correlates the measured neurological change to the TMS stimulus.
