Subacute to Chronic Stroke: (Johansson & Hager, 2011; n= 42; mean age = 56 (12) years; mean time post stroke = 7 months (range 3 - 15.3 months)

• SEM for Arm test (/40) = 2.2 points
• SEM for Hand test (/18) = 0.94 points
• SEM for Total score (/ 58) = 2.68 points

Subacute to Chronic Stroke: (Johansson & Hager, 2011; n= 42; mean age = 56 (12) years; mean time post stroke = 7 months (range 3 - 15.3 months)

• MDC for Arm test (/40) = 6.10 = 7 points
• MDC for Hand test (/18) = 2.61 = 3 points
• MDC for Total score (/58) = 7.43 = 8 points

Subacute to Chronic Stroke: (Johansson & Hager, 2011; n = 42; mean age = 56 (12) years; mean time post stroke = 7 months (range 3 - 15.3 months) and Van de Winckel et al., 2006, n = 56)

• Excellent inter-rater reliability for Arm test (ICC = .95)
• Excellent inter-rater reliability for Hand test (ICC = .97)
• Excellent inter-rater reliability for Total score (ICC = .98)
• Good to very good inter-rater reliability with weighted kappa coefficient = 0.62-0.79 (Van de Winckel et al., 2006); weighted kappa coefficient = 0.63-0.96 (Johansson & Hager, 2012)
• Good to very good inter-rater reliability with weighted percentage agreement = 85.71-98.21; Scores were not derived for hand function items as 42% of the sample scored 0 (Van de Winckel et al., 2006).

Subacute to Chronic Stroke: (Van de Winckel et al., 2006, n = 56)

• Excellent internal consistency for Arm test (person separation index in Rasch analysis, measurement for internal consistency comparable to Chronbach¡¯s alpha = 0.99)
• Excellent internal consistency for Hand test (person separation index = 0.97)

Concurrent validity: Subacute to Chronic Stroke: (Johansson & Hager, 2012, n = 42)

• Excellent concurrent validity between MESUPES Arm test and Modified Motor Assessment Scale (MMAS) (Spearman¡¯s rho = 0.84) 
• Excellent concurrent validity between MESUPES Hand test and MMAS (r= 0.80)
• Excellent concurrent validity between MESUPES Total score and MMAS (r= 0.87)

Convergent Validity

Portuguese Stroke Patients: (Branco JP, et al., 2017; n=122 Portuguese stroke patients)

• Excellent convergent validity between MESUPES Hand test and Stroke Upper Limb Capacity Scale (SULCS) (r= 0.873)
• Excellent convergent validity between MESUPES Arm test and SULCS (r=0.874)
• Excellent convergent validity between MESUPES Total score and SULCS (r=0.914)

Subacute to Chronic Stroke: (Van de Winckel et al., 2006, n = 396) 

• Excellent content validity (unidimensionality of Arm test and Hand test): Rasch analysis was performed on the original scale of 22 items (Perfetti & Dal Pezzo, 1995). Five items were removed and the arm scale and hand scale were assessed separately. Rasch analysis of the remaining 8 arm items and 9 hand items and their fit statistics (i.e. ¦Ö2 comparing observed scores with a predicted model) confirmed unidimensionality of both arm (¦Ö2 = 31.22, DF = 40, p = 0.84) and hand scales (¦Ö2 = 46.21, DF = 45, p = 0.42).
• Excellent internal consistency across subgroups of patients with stroke: Van de Winckel et al. (2006) demonstrated that the hierarchy of the items (from easy to difficult) is maintained across subgroups of adults with stroke: gender; age.

Subacute to Chronic Stroke: (Van de Winckel et al., 2006, n = 396) 

• Excellent: No floor- or ceiling effect observed for the Total test (min score of 0 on Total score = 8/396 or 0.02%) (max score of 58 on Total score = 12/396 or 0.03%)
• Of note: The data on 396 patients with subacute to chronic stroke demonstrated that 163/396 (42%) do not recover hand function after stroke and therefore had a score of 0 on the hand items, whereas only 76/396 (19%) achieved a maximum score on the arm items.
