Evaluating effects of method of administration on Walking Impairment Questionnaire. J Vasc Surg.
Perception of functional ability and quality of life was measured with the Medical Outcomes Scale Short Form-36 (SF-36) and the Walking Impairment Questionnaire. In addition, physicians and patients were asked for their subjective assessment of benefit at the end of treatment.
Scores on the SF-36 and the Walking Impairment Questionnaire revealed no significant differences in general health perception or patient-reported walking distance.
The Walking Impairment Questionnaire
provided evidence that walking distance improved 389%, speed improved 213%, and stair-climbing improved 23%.
At follow-up, the exercise group had better improvement in walking distance, walking speed, and stair-climbing ability than did the sedentary group; the two groups did not differ in claudication severity on the Walking Impairment Questionnaires
