Abstract: © 2018 The Author(s). Background: Upper limb hemiplegia following cerebrovascular diseases can result in significant functional limitation. To assess such functional disturbance requires a comprehensive, valid and reliable tool. The Arm Activity Measure (ArmA) is a comprehensive, valid and reliable self-report questionnaire to assess real-life function for upper limb hemiplegia. However, it has never been translated for use in different languages. The purpose of this study is to translate and cross-culturally adapt the Arm Activity Measure (ArmA) questionnaire into a Thai version and to evaluate content validity, internal consistency and feasibility. Methods: The ArmA was translated and culturally adapted according to published cross-cultural adaptation guidelines resulting in the Thai version of ArmA (ArmA-TH). Forty Thai patients with upper limb hemiplegia resulting from cerebrovascular disorders participated in field-testing of the ArmA-TH. Its feasibility was evaluated. Content validity index for item (I-CVI) and score (S-CVI) were examined. Inter-rater reliability was evaluated by Gwet's AC2. Internal consistency was measured using Cronbach's alpha coefficient. Results: Forty patients (29 males, 11 females) with upper limb spasticity due to stroke or TBI were included. The average age of patients was 54.5 years (SD 15.0). Twenty-seven patients (67.5%) completed the questionnaire within 5 min or less, average time taken was 4.45 (1.73) min. For both subscales, patients reported the ArmA-TH to be relevant (85%) and easy to use (67.5%). More than 80% of patients found the passive subscale useful, almost 80% found the active subscale useful. Overall S-CVI was 0.83, S-CVI for passive and active function subscale was 0.79 and 0.86 respectively. The inter-rater reliability coefficients for ArmA-TH was 0.81. Cronbach's alpha was 0.90 for the overall ArmA, 0.89 and 0.88 for the passive and active function subscales. Conclusions: The ArmA-TH was a feasible self-report questionnaire to assess hemiplegic upper limb function with good content validity, inter-rater reliability and internal consistency.
