This paper reports on a pre-post study on outcomes of rollator interventions in terms of mobility-related participation frequency and ease, and of users perceptions of the importance of the device. Data were collected in two municipalities with 37 and 38 respondents, in average 77 and 82 years of age. Taking walks became more frequent and easier, and in one of the municipalities it also became easier to go to the pharmacy, the post office and the library, to do shopping and to visit families and friends. Most users considered their device to be important, but there was an increased risk that the oldest users would not rate the device as important. Reasons for modest outcomes and for municipality differences are discussed.
