5. Study Description

Brief Summary
The investigators aim to evaluate the user friendliness of a newly designed leg compression stocking kit, the SOCKNLEG, compared to a standard leg compression stocking of the same compression strength, the SIGVARIS Cotton. The SOCKNLEG is not yet commercially available, whereas the SIGVARIS Cotton has been successfully commercialized for many years. After an initial screening visit, a computer generated list will allocate the participants in either the SOCKNLEG or the SIGVARIS Cotton group. All participants will try on both study stockings, in the order of their allocated group, and will rate their donning and doffing success with a questionnaire. The patients will then wear only the assigned study stocking of their allocated group, for a day and rate its comfort again at the end of the day. The donning and doffing success will also be rated by the study investigator. Leg volume measurements of the study leg will be taken at each visit to determine edema prevention.
