“…Average scores obtained on the WIQ subscales in patients with OA are slightly higher than those reported by patients with PAD and lower than those without PAD [13][14]21,[32][33][34][35][36][37][38][39]. In patients with PAD, scores on the walking distance subscale ranged from 25 to 56 [13][14][32][33][34][35]37,39], with most scores clustering at 40 or lower. In patients whose lifestyle was limited by decreased circulation to their legs or who were awaiting surgery, scores were lower, ranging from 3.1 to 12.6 [36,38].…”

“…The scores are in the upper range of PAD patients and well below those reported by patients without disease. Likewise, patients with decreased circulation to the legs scored between 30 and 39 [13][14][32][33][34][35]37,39] on the walking speed subscale, with severely limited PAD patients scoring between 4.6 and 22.0 [36,38]. Subjects without disease reported scores ranging from 60 to 64 [32,35].…”

Abstract-This study tested the psychometric properties of the Walking Impairment Questionnaire (WIQ) in overweight patients with osteoarthritis (OA) of the knee. Internal consistency, test-retest reliability, and concurrent validity of the WIQ were measured. Used in a randomized clinical trial, the WIQ was one of the instruments completed by overweight adults with OA of the knee. A total of 105 patients completed the WIQ. Internal consistency of the WIQ was supported in this population with a Cronbach alpha total score of 0.97. Testretest reliability scores were not different when subjects completed the WIQ 14 days apart (p > 0.05). The relationships were moderate between the WIQ subscales and other established measures, such as the 6-minute walk distance, stair climb and descend, and the Western Ontario and McMaster Universities (OA Index) questionnaire. After evaluating the psychometric properties of the WIQ, we found that it is a valid and reliable instrument to use in overweight patients with symptomatic OA of the knee.

Summary:Background: Auricular nerve stimulation has been proven effective in different diseases. We investigated if a conservative therapeutic alternative for claudication in peripheral arterial occlusive disease (PAD) via electroacupuncture of the outer ear can be established. Patients and methods: In this prospective, double-blinded trial an ear acupuncture using an electroacupuncture device was carried out in 40 PAD patients in Fontaine stage IIb. Twenty patients were randomized to the verum group using a fully functional electroacupuncture device, the other 20 patients received a sham device (control group). Per patient, eight cycles (1 cycle = 1 week) of electroacupuncture were performed. The primary endpoint was defi ned as a signifi cantly more frequent doubling of the absolute walking distance after eight cycles in the verum group compared to controls in a standardized treadmill testing. Secondary endpoints were a signifi cant improvement of the total score of the Walking Impairment Questionnaire (WIQ) as well as improvements in health related quality of life using the Short Form 36 Health Survey (SF-36). Results: There were no differences in baseline characteristics between the two groups. The initial walking distance signifi cantly increased in both groups (verum group . SF-36 showed signifi cantly improvements in six out of eight categories in the verum group and only in one of eight in controls. Conclusions: Electroacupuncture of the outer ear seems to be an easy-to-use therapeutic option in an age of increasingly invasive and mechanically complex treatments for PAD patients.

CONTEXT AND OBJECTIVE: Many clinical investigations use generic and/or specific questionnaires to obtain information about participants and patients. There is disagreement about whether the administration method can affect the results. The aim here was to determine whether, among patients with intermittent claudication (IC), there are differences in the Walking Impairment Questionnaire (WIQ) and European Quality of Life-5 Dimension (EQ-5D) scores with regard to: 1) the questionnaire administration method (self-administration versus face-to-face interview); and 2) the type of interviewer (vascular surgeon, VS, versus general practitioner, GP). DESIGN AND SETTING: Cross-sectional observational multicenter epidemiological study carried out within the Spanish National Health Service. METHODS: 1,641 evaluable patients with IC firstly completed the WIQ and EQ-5D questionnaires and then were interviewed by their doctor on the same day. Pearson correlations and Chi-square tests were used. RESULTS: There was a strong correlation (r > 0.800; P < 0.001) between the two methods of administering the WIQ and EQ-5D questionnaires, and between the VS and GP groups. Likewise, there was a high level of concordance (P > 0.05) between the different dimensions of the WIQ-distance and EQ-5D (selfadministration versus face-to-face) in the VS and GP groups. CONCLUSION: There was no difference between the different methods of administering the WIQ and EQ-5D questionnaires, among the patients with IC. Similarly, the two types of interviewers (VS or GP) were equally valid. Therefore, it seems unnecessary to expend effort to administer these questionnaires by interview, in studies on IC. RESULTADOS: Houve forte correlação (r > 0,800; P < 0,001) entre os dois métodos de administração do WIQ e EQ-5D; e entre os grupos CV e MG. Também houve alto nível de concordância (P > 0,05) entre as diferentes dimensões do WIQ-distância e EQ-5D (autoadministrado versus entrevista presencial), nos grupos CV e MG. CONCLUSÃO: Em pacientes com CI, não há diferenças entre as diferentes formas de administrar os questionários WIQ e EQ-5D. Da mesma forma, os dois tipos de entrevistador (CV ou MG) foram igualmente válidos. Portanto, não parece necessário despender esforço para administrar esses questionários através de entrevista, em estudos de CI. RESUMO

Evaluating effects of method of administration on Walking Impairment Questionnaire

Abstract: The modified WIQ demonstrated good reliability and validity with both methods of administration. These results suggest that the self-administered and telephone-administered versions of the WIQ can be used reliably and efficiently in clinical trials.
