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.

Feasibility of Ultrasound Guided Atlanto-occipital Joint Injection

OBJECTIVE: To evaluate the feasibility of ultrasound guided atlanto-occipital joint injection. METHOD: Six atlanto-occipital joints of three cadavers were examined. Cadavers were placed in prone position with their head slightly rotated towards the contra-lateral side. The atlanto-occipital joint was initially identified with a longitudinal ultrasound scan at the midline between occipital protuberance and mastoid process. Contrast media 0.5cc was injected into the atlanto-occipital joint using an in-plane needle approach under ultrasound guide. The location of the needle tip and spreading pattern of the contrast was confirmed by fluoroscopic evaluation. RESULTS: After ultrasound guided atlanto-occipital joint injection, spreading of the contrast media into the joint was seen in all the injected joints in the anterior-posterior fluoroscopic view. CONCLUSION: The ultrasound guided atlanto-occipital injection is feasible. The ultrasound guided injection by Doppler examination can provide a safer approach to the atlanto-occipital joint.
