Abstract: Objective To verify the convergent validity,discriminant validity and concurrent validity of the Action Research Arm Test(ARAT)in patients with chronic stroke.Methods 30 cases with chronic stroke were assessed with ARAT,upper limb section at Fugl-Meyer Assessment and Motor Activity Log(MAL)on the same day.The validity was investigated using Spearman ρ and t test.Results The scores of the ARAT closely correlated with upper limb section at Fugl-Meyer Assessment(ρ=0.906,P<0.001).The upper limb section at Fugl-Meyer scores≥33 group achieved a significantly higher scores of the ARAT than the scores<33 group(t =6.614,P<0.001).The scores of the ARAT closely correlated with the amount of use(AOU)and quality of movement(QOM)of MAL(ρ=0.894 and 0.761,respectively,P<0.001).Conclusion The ARAT has been shown good convergent validity,discriminant validity and concurrent validity in people with stroke.
