Detailed Description:

The ability to accurately measure daily activity levels in lower extremity amputee patients is important for a better understanding of their use of prosthetic limbs. Most studies have shown that patients often report their activity level inaccurately. More objective data on activity levels will not only provide information helpful for determining the appropriate prosthetic components for an individual, it will also be helpful when assessing the effects that medical illness have on activity levels and in objectively determining the benefits of rehabilitation. In addition, being able to measure activity accurately will allow further verification of currently developed clinical surveys designed to determine amputee activity in a practical form.

Until more recently a practical, accurate and affordable means of monitoring lower extremity amputee activity has not been available for use. Currently a monitoring device designed specifically for this task is available for research use. It is called the Patient Activity Monitor (PAM). Many different models of more generic activity monitoring devices, called pedometers, also exist and need to be further tested in the amputee population.

The objective of our study was to measure and compare the step count and ambulation distance accuracies of a Yamax Digi-Walker pedometer and the PAM in transtibial amputees at the K3 Level within a simulated apartment setting and during relatively continuous gymnasium walking.
