  1. MAS: Modified Ashworth Scale; MOCA: Montreal cognitive assessment; NHPT: Nine Hole Peg Test; EmNSA: Erasmus MC modifications to the Nottingham Sensory Assessment; BBT: Box and Block Test; ARAT: Action Research Arm Test; FMA-UE: Fugl-Meyer Assessment Upper Extremity; GF: grip force. SPARC: spectral arc length. num: number. vel: velocity. TP: transport. RT: return. PA: peg approach. HA: hole approach. The Bonferroni-corrected significance level was 0.05/13=0.0038 for the correlations with the BBT, ARAT, and NHPT, and 0.05/10=0.005 for all other conventional scales
  2. Spearman correlation analysis was applied to analyze the relationship of conventional scales and VPIT metrics. Only data collected during the first testing session with the most affected body side was considered for this analysis. *indicates a p-value below 0.05 and **indicates a p-value below the Bonferroni-corrected significance level. Bonferonni correction was applied within each table row
