Validation of the telephone-based assessment of locomotion ability after stroke.

The aim of the study was to validate the telephone-based application of the ABILOCO questionnaire for the assessment of locomotion ability after stroke. Individuals after stroke answered the ABILOCO-Brazil questionnaire on two randomized occasions, face-to-face and by telephone, 5-7 days apart. The mean difference between the interviews was reported. Intraclass correlation coefficient (ICC) was calculated to investigate the agreement between the total scores, and weighted-Kappa statistics to investigate the agreement between the individual items. A total of 92 individuals were included. There was no significant difference in the mean scores between face-to-face and telephone-based applications of the ABILOCO [mean difference 0.17 logits; 95% confidence interval (CI), -0.88 to 0.54]. A high level of agreement was found between the ABILOCO total scores obtained between both applications (ICC = 0.90; 95% CI, 0.84-0.93), and most of the individual items had, on average, moderate agreement. The ABILOCO showed to be a reliable questionnaire for telephone assessment of locomotion ability after stroke.

Validation of the Telephone-Based Application of the ABILHAND for Assessment of Manual Ability After Stroke.

BACKGROUND AND PURPOSE: Telephone-based assessment may be a valuable and cost-effective approach to improve monitoring and follow-up assessments in patients and research participants. Telephone-based assessment may be of particular value during times when it is important to reduce in-person contract, such as during the Covid-19 pandemic. The purpose of this study was to investigate concurrent validity of the telephone-based administration of the ABILHAND for the assessment of manual ability in individuals with stroke. METHODS: Using a cross-sectional study design, participants with stroke were invited to answer the ABILHAND questionnaire on 2 randomized occasions, face to face and by telephone, 5 to 7 days apart. The mean difference (MD) between the interviews was calculated (95% confidence interval [95% CI]) to investigate the concurrent validity. Intraclass correlation (ICC) and weighted κ coefficients were used to investigate the agreement between face-to-face and telephone-based administration. RESULTS: One hundred two participants (50 men; mean age = 65 years, SD = 13 years) were included. No significant differences were observed between the mean scores obtained with face-to-face and telephone-based administration of the ABILHAND (MD = -0.06; 95% CI, -0.72 to 0.60). Very high agreement was found between face-to-face and telephone-based administration (ICC = 0.90; 95% CI, 0.85 to 0.93) on the ABILHAND total scores. Most of the individual items had moderate or substantial κ agreement. DISCUSSION AND CONCLUSIONS: Telephone-based administration of the ABILHAND is valid for the assessment of manual ability after stroke. Clinicians and researchers may use the ABILHAND for monitoring manual ability in persons with stroke and/or screening potential research participants.Video Abstract available for more insights from the authors (see the Video, Supplemental Digital Content 1, http://links.lww.com/JNPT/A318).
