Accurate devices to measure activity levels in patients with a lower-limb amputation can benefit patient care and research. In this study, we found that both the Yamax Digi-Walker SW-700 and the Össur patient activity monitor accurately measure step count during continuous walking in patients with a below-knee amputation. However, these devices were not accurate for measuring step count during short distance walking in a small indoor environment such as an apartment. Therefore, these devices can presently only be recommended for use during relatively continuous walking.
