Motor Evoked Potentials With Modified Facilitation Technique (EP-F)

Motor Evoked Potentials With Modified Facilitation Technique: Normative Data and Reliability in Healthy Individuals and Comparison of Sensitivity and Specificity With Standard Technique in Patients With Multiple Sclerosis

Investigating the change in Test- Retest- reliability in healthy individuals when applying a modified easy to use facilitation technique compared to standard facilitation technique and analyzing sensitivity and specificity in patients with multiple sclerosis regarding detection of pathologic results

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
OTHER: healthy individuals and patients with multiple sclerosis
MEP in healthy individuals and patients with multiple sclerosis are measured using standard facilitation technique
measuring of MEP using standard facilitation technique according to the Guidelines of International Federation of Clinical Neurophysiology
OTHER: patients with multiple sclerosis
MEP in patients with multiple sclerosis are measured using modified facilitation technique
measuring of MEP using standard facilitation technique according to the Guidelines of International Federation of Clinical Neurophysiology
measuring of MEP using modified facilitation technique (application of additional 8-12x magnetic stimuli for arms and legs)

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Test- Re-Test reliability when using modified facilitation technique (compared to standard facilitation technique) in healthy individuals
Time Frame: measuring time 2 (75 minutes) maximal 1 month later than measuring time 1 (75 minutes)
Determination of mean intra-individual difference between measuring time 1 and measuring time 2 and calculation of standard deviation
measuring time 2 (75 minutes) maximal 1 month later than measuring time 1 (75 minutes)
comparison of sensitivity and specificity of modified facilitation technique and standard facilitation technique in patients with multiple sclerosis
Time Frame: 1 measuring time (90 minutes)
Determination on the basis of the standard values (established in healthy individuals) in how many patients a pathological result with the modified facilitation technique and the standard facilitation technique is present. Using a a cross-tabulation, the sensitivity and specificity of the modified facilitating technique compared to the standard facilitation technique is measured
1 measuring time (90 minutes)
