Abstract

Maintaining physical activity for lower limb prosthesis wearers is important in order to reduce comorbidities and decrease physical function. Activity monitors can provide motivation for the wearer and outcome measurements for the health care professional. Two cohorts of lower extremity amputees participated in two separate studies examining the accuracy of activity monitors. Each participant completed a 200m walking trial while activity monitors were fitted to them and step counts were compared with actual counts. For participants walking on even ground in a developing setting no significant differences between pedometer and actual counts were found, nor were there significant differences with pedometers placed at various locations on the body. In both developed and developing settings on even and uneven terrain, percentage errors were greatest with the pedometer on the neck strap and least at the hip. For individuals walking on uneven ground, no significant differences between actual counts and activity monitor counts were found. The Omron HJ-329 pedometer is a reliable activity monitor for persons living in developed and developing countries.
