Background: The Intermittent Claudication Questionnaire (ICQ) is a short questionnaire for the assessment of health-related quality of life (HRQOL) in patients with intermittent claudication (IC). The objective of this study was to translate the ICQ into German and to investigate the psychometric properties of the German ICQ version in patients with IC. Patients and methods: The original English version was translated using a forward-backward method. The resulting German version was reviewed by the author of the original version and an experienced clinician. Finally, it was tested for clarity with 5 German patients with IC. A sample of 81 patients were administered the German ICQ. The sample consisted of 58.0 % male patients with a median age of 71 years and a median IC duration of 36 months. Test of feasibility included completeness of questionnaires, completion time, and ratings of clarity, length and relevance. Reliability was assessed through a retest in 13 patients at 14 days, and analysis of Cronbach’s alpha for internal consistency. Construct validity was investigated using principal component analysis. Concurrent validity was assessed by correlating the ICQ scores with the Short Form 36 Health Survey (SF-36) as well as clinical measures. Results: The ICQ was completely filled in by 73 subjects (90.1 %) with an average completion time of 6.3 minutes. Cronbach’s alpha coefficient reached 0.75. Intra-class correlation for test-retest reliability was r = 0.88. Principal component analysis resulted in a 3 factor solution. The first factor explained 51.5 of the total variation and all items had loadings of at least 0.65 on it. The ICQ was significantly associated with the SF-36 and treadmill-walking distances whereas no association was found for resting ABPI. Conclusions: The German version of the ICQ demonstrated good feasibility, satisfactory reliability and good validity. Responsiveness should be investigated in further validation studies.

The purpose of this study is to describe layout and elements of the movement labor, determine cake making job completion time before and after repair, complaints of pain workers and recomendation improved layout and elements work in ergonomic aspects. Layout and elements of the cake making job is less visible than ergonomic working conditions with temperatures as high as 290C and 300C, total distance moving much material for the production namely 2407 cm, manufacture molen 180 cm, 2926 cm baking and packaging 626 cm. Percentage of use right and left hand at creation pia cake is 50.11% and 54.4%. Making molen is 100% and 76.69%. Pia cake making is 12.76% and 12.21%. Packaging is 100% and 84.8%. Cycle time, normal time and standard time of content creation, namely 17004.15, 18.534.52 and 25.577.64 seconds (2 basins). Making molen is 560.23, 616.25 and 751.82 seconds (1 basin). Pia cake making is 1.165,45, 1314.63 and 1.603,85 seconds (2 trays), and packaging is 15,40, 16,79 and 23.17 seconds (2 pack). The application of ergonomics : 8 types of grievances felt a bit sick and 1 type of grievances felt sick. Station molen manufacture, workers felt no pain. Baking station pia (sub-stations) only complaint molen rolling on his back felt a little sore. Sub-station charging only 3 workers who feel a little pain complaints and pain. In the sub-station : 6 types pengovenan grievances felt a little sick. The packing station after repairs only felt a little pain in the waist
