Correlation of the Hand 20 with the International Classification of Functioning, Disability, and Health and comparison of the results with those of the Disability of the Arm, Shoulder and Hand

抄録

The present study aimed to determine the correlation of the Hand 20, a patient-based outcome evaluation widely used in Japan, with the International Classification of Functioning, Disability, and Health (ICF) and compare the results with those of previous studies on the Disability of the Arm, Shoulder and Hand (DASH) score. As a result of the study, it was found that the Hand 20 includes 5 items in the chapters of Body Functions, 23 items in the chapters of Activity/Participation, and 2 items in the chapters on Personal Factors in the ICF. The results show that the Hand 20 has a larger number of assessment items categorized into the muscle function (b740) and hand dexterity (d440) than that of DASH. The present study concludes that the Hand 20 is a measurement method suitable for assessing hand functions and performance. These findings provide insights to select appropriate outcome assessment methods and interpret outcomes between the two different methods.
