Rasch analysis of The Melbourne Assessment of Unilateral Upper Limb Function

Abstract

ABBREVIATIONS DIFMETHOD Rasch analysis was used to assess of Melbourne Assessment raw scores for 163 children (94 males, 69 females; mean age 8y, SD 3y 5mo). Analysis was undertaken on the full scale comprising 37 scores and on groups of scores separated into four distinct movement subscales: range of movement, accuracy, dexterity, and fluency. Tests were conducted to evaluate overall model fit, item fit, suitability of the response options, unidimensionality, and differential item functioning (DIF) for sex, child age, and different raters. RESULTSThe results did not support the unidimensionality of the 37-score scale. The four subscales showed adequate model fit after removal of some score items, and rescaling of others. The resulting subscales showed good internal consistency and no DIF for sex or child age.

Effect of parent‐delivered action observation therapy on upper limb function in unilateral cerebral palsy: a randomized controlled trial

“…Outcome measures were selected based on published recommendations, 18 to give a comprehensive overview of performance, 19 capacity, 17 and function. 13 All three have excellent psychometric properties.…”

“…The MA2 is a reformulation of the MUUL with improved psychometric properties; however, standard error of measurement and smallest detectable difference have not yet been defined. 17 Nonetheless, small but significant improvements were observed in the combined group data in all three outcome measures used. Our approach is accessible and the findings generalizable within the age group studied.…”

“…Baseline assessments, specifically AHA, 12 Melbourne Assessment-2 (MA2), 17 and ABILHAND-Kids, 13 were used to establish areas of difficulty in manual activities for each child, such as reaching, grasp, and manipulating small items. These, along with the child's interests and abilities, informed the choice of intervention activities.…”

“…Його перша версія була опублікована в 1999 році групою працівників Мельбурнської коро-лівської дитячої клініки під керівництвом Мелінди Рендел (Melinda Randall) [44]. Протягом наступних років команда продовжувала працювати над покра-щанням тесту, внаслідок чого було розроблено другу, удосконалену версію.…”

Upper limb function in everyday life of children with cerebral palsy: description and review of parent report measures

“…Many upper limb interventions for children with cerebral palsy aim to improve upper limb function with a view to enhance children's capacity to complete daily activities. Clinical measures such as the Quality of Upper Extremity Skills Test [1] and Melbourne Assessment 2 [2] capture upper limb capacity in clinical environments, or children's best ability to use their upper limb. Children with cerebral palsy, however, are less likely to spontaneously involve their affected upper limb during play or self-care tasks in everyday environments than during clinic-based assessment or therapy sessions [3].…”
