Korean version of the ABILOCO questionnaire in the assessment of locomotion in hemiplegic stroke patients

Objective: To investigate the intra- and inter-rater reliability of the Korean version of the ABILOCO questionnaire (K-ABILOCO). Methods The original ABILOCO questionnaire was translated into Korean and back-translated into English. Stroke patients (n=30) with hemiplegia were evaluated using the K-ABILOCO at one week interval. At each visit, the physiatrist also evaluated patient performance of the activities described in the K-ABILOCO, and the total logit scores were recorded. The total scores were used to evaluate intraclass correlation (ICC). Test-retest scores and each test scores were compared to obtain the intra- and inter-rater reliability. Results The K-ABILOCO showed good intra-rater correlation at one week interval in both patient and physiatrist evaluations (ICC=0.81, 0.91), respectively. It also showed a high inter-rater correlation between the patient and physiatrist at both the first and second visits (ICC=0.76, 0.84), respectively. Conclusion The K-ABILOCO is a useful tool that may reliably evaluate the locomotion ability in hemiplegic stroke patients.
