Primary Outcome Measures
NameTimeMethod
Inflammatory Neuropathy Cause and Treatment (INCAT) disability score2 weeks

Standard clinical score for inflammatory neuropathies.

Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) Score2 weeks

Combined score consisting of Inflammatory Neuropathy Cause and Treatment (INCAT) disability score, Oxford muscle strength score, and vibration score, equally weighted

Oxford Muscle Strength Score (Medical Research Council, MRC)2 weeks

Standard clinical score for evaluating muscle strength / paresis. Muscle strength will be measured on a scale between 0 (no movement) and 5 (full strength) on 8 pre-defined muscles (one proximal and one distal muscle at each extremity).

Vibration Score2 weeks

Standard clinical score for evaluation of vibration sensitivity on a scale between 0 and 8, using a 256 tuning fork at 4 predefined spots (processus styloideus radii and malleolus lateralis on both sides).

Secondary Outcome Measures
NameTimeMethod
