Brief summary

The aim of the study is to validate the Korean version of Walking Impairment Questionnaire in patients with peripheral arterial occlusive disease.

Detailed description

First, the original version of WIQ will be translated into Korean, then it will be translated into English, again. The translated version will be sent to the original author to compare with the original version. After correcting, the Korean version will be completed. The patients with peripheral arterial disease will fill in the Korean version of WIQ before starting treatments. Baseline results of arterial function test, toe-brachial index and treadmill test will be recorded. Three months later, the patients will complete the questionnaire again. Arterial function test, toe-brachial index and treadmill test also will be taken again after treatment and the correlation of WIQ and other exams will be evaluated.

Design outcomes

Primary

Measure	Time frame	Description
Reproducibility of Korean version Walking Impairment Questionnaire	One month	To test reliatbility of WIQ Korean ver., reproducibility of the test was assessed by test-retest procedure of the baseline and 1month afterwards (intraclass correlation coefficient)
Correlation of WIQ score improvement and change in ABI and treadmill test results	3 months	Correlation between changes in WIQ score and changes in ABI or treadmill test results (before and after surgical / radiological or pharmacological intervention) were assessed by Pearson's correlation test
