Outcome Measures
Primary Outcomes (1)
Motor Performance of Unified Parkinson's Disease Rating Scale
To assess Unified Parkinson's Disease Rating Scale part III (motor function) scores from baseline Medication-off status to Medication-off status after G-CSF injection one year. Scores of UPDRS Part III ranges from 0 to 108 and higher values indicate worse outcome.
