Despite the availability of numerous stroke rehabilitative therapies, such as mirror therapy, bilateral arm training, and robot-assisted therapy, the recovery of motor function after stroke remains incomplete. Bilateral arm function is a key component in stroke patients to perform activities of daily living and to reflect their functional autonomy.<\/jats:p><\/jats:sec><jats:sec><jats:title>Objective<\/jats:title><jats:p>This clinimetric study investigated and compared the construct validity and responsiveness of 2 bimanual activity outcome measures, the Chedoke Arm and Hand Activity Inventory (CAHAI) and the ABILHAND Questionnaire, in individuals receiving stroke rehabilitation.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>The present study is a secondary analysis following the framework of the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN). Individuals with chronic stroke (<jats:italic>N<\/jats:italic> =\u2009113) were recruited from outpatient rehabilitation settings. Participants received 18 to 20 sessions of robot-assisted therapy, mirror therapy, combined therapy, or conventional rehabilitation for 4 to 6\u2009weeks. The CAHAI, ABILHAND Questionnaire, and a comparison instrument, the Motor Activity Log (MAL), were administered twice at a 4- to 6-week interval to all participants. ABILHAND scores, in logits, were converted from raw ordinal scores into a linear measure.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>There was medium to large correlation of the CAHAI and the MAL (<jats:italic>\u03c1<\/jats:italic> =\u20090.60\u20130.62, <jats:italic>p<\/jats:italic> &amp;lt;\u20090.01) as well as the ABILHAND Questionnaire and the MAL (<jats:italic>\u03c1<\/jats:italic> =\u20090.44\u20130.51, <jats:italic>p<\/jats:italic> &amp;lt;\u20090.01). Change scores from the initial measurement to the post-intervention measurement demonstrated small to medium correlation of the CAHAI and the MAL (<jats:italic>\u03c1<\/jats:italic> =\u20090.27\u20130.31, <jats:italic>p<\/jats:italic> &amp;lt;\u20090.01) and medium to large correlation of the ABILHAND Questionnaire and the MAL (<jats:italic>\u03c1<\/jats:italic> =\u20090.37\u20130.41, <jats:italic>p<\/jats:italic> &amp;lt;\u20090.01). Overall, 7 of 8 hypotheses were supported. The hypothesis testing regarding the construct validity and responsiveness of the CAHAI and ABILHAND Questionnaire was confirmed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The CAHAI and ABILHAND Questionnaire are both responsive and suitable to detect changes in bilateral arm functional daily activities in individuals with chronic stroke. Patient-reported outcome measures are recommended to use along with therapist-rated outcome measures for upper limb capacity evaluation in stroke rehabilitation. Further study with a prospective study design to capture specific clinical features of participants and the use of body-worn sensors, such as the arm accelerometer, is suggested.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fneur.2024.1352365","type":"journal-article","created":{"date-parts":[[2024,5,23]],"date-time":"2024-05-23T04:44:07Z","timestamp":1716439447000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":4,"title":["Responsiveness
