Background

Motor impairment in Parkinson¡¯s disease (PD) can be evaluated with the Short Parkinson¡¯s Evaluation Scale/Scales for Outcomes in Parkinson¡¯s disease (SPES/SCOPA) and the Movement Disorder Society-Unified Parkinson¡¯s Disease Rating Scale (MDS-UPDRS). The aim of this study was to determine equation models for the conversion of scores from one scale to the other.

Methods

148 PD patients were evaluated with the SPES/SCOPA-motor and the MDS-UPDRS motor examination. Linear regression was used to develop equation models.

Results

Scores on both scales were highly correlated (r?=?0.88). Linear regression revealed the following equation models (explained variance: 78 % ):

• 1.	MDS-UPDRS motor examination score?=?11.8?+?2.4???SPES/SCOPA-motor score

• 2.	SPES/SCOPA-motor score?=??.5?+?0.3???MDS-UPDRS motor examination score.

Conclusion

With the equation models identified in this study, scores from SPES/SCOPA-motor can be converted to scores from MDS-UPDRS motor examination and vice versa.
