Estimation of Motor Impairment and Usage of Upper Extremities during Daily Living Activities in Poststroke Hemiparesis Patients by Observation of Time Required to Accomplish Hand Dexterity Tasks

Table 3

Relationships between SHAP Heavy Power item score and FMA or JASMID score.

	α	β	R^2
FMA
Upper extremity, motor score	64.55	−1.66	0.344	<0.0001
JASMID
Frequency	86.26	−2.21	0.076	0.010
Quality	83.28	−2.77	0.126	0.001

SHAP: Southampton Hand Assessment Procedure, FMA: Fugl-Meyer Assessment, JASMID: Jikei Assessment Scale for Motor Impairment in Daily Living. The coefficient of determination (R²) was used in the linear regression analysis: f (x) = α + β (x). f (x): the SHAP Heavy Power item score; x: BR, FMA, or JASMID score; α: function constant; β: unstandardized regression coefficient.
