Improvement by Medication Less than Expected in Parkinson’s Disease: Blinded Evaluation of Levodopa Response

Figure 2

Motor improvement ON compared to OFF in UPDRS-III for all patients with PD. The oblique line shows cutoff 30%. 12 PD had self-rated a good medicine response, but we measured an L-dopa response ≤30%. On the other hand, 4 PD had self-rated a poor medicine response, but we measured a good L-dopa response.
