Sponsored by Seoul National University Hospital · Observational
The aim of the study is to validate the Korean version of Walking Impairment Questionnaire in patients with peripheral arterial occlusive disease.
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.
1,542 studies on the registry are indexed under Peripheral Arterial Disease; 282 are open to participants now.
This study's enrollment of 47 is below the median of 190 across 410 observational studies indexed under Peripheral Arterial Disease.

Patients with peripheral arterial disease
Exclusion Criteria:
only medical treatment (regardless of the kinds of medicine)
patients underwent surgery or endovascular therapy
Reproducibility of Korean version Walking Impairment Questionnaire
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)
Time frame: One month
Correlation of WIQ score improvement and change in ABI and treadmill test results
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
Time frame: 3 months
