Study undertaken to determine the accuracy of self-reported activity by community-dwelling, lower-limb amputees. Seventy-seven unilateral lower-limb amputees at least 6 months after prosthetic rehabilitation were recruited for the study from a regional prosthetics outpatient service. Participants kept an activity diary, which consisted of a table for each day of the week, with rows corresponding to time in 15-minute increments and the columns corresponding to 4 defined levels of activity, from resting to high. The StepWatch3 Activity Monitor (SAM) was fitted to the participant’s prosthesis. Measured activity counts (in steps/min) and self-reported activity (rest, low, medium, high) in 15-minute intervals over 1 week were recorded for each participant. Strong agreement between self-reported and measured activity, except for the resting level, was found for only 34% of participants. The measured and self-reported proportion of time spent in various states of activity also showed poor agreement. Implications for prescribing prosthetics and providing patients with advice on promoting health are discussed.
