Abstract

After performing total knee or hip arthroplasty, an orthopedic surgeon would be significantly aided in monitoring oth a patient's daily limb activity could be quantitatively assessed. A device used in such assessment should not only provide accurate measurements of the afflicted joint's aggregate angular motion, but should also have a practical design that permits the patient to wear it for long periods in settings associated with daily living. Additionally, for the sake of practicality in long-term use, a device that is small, self-contained, and easily attached and detached at or near the joint would be desired. The IUPUI Activity Monitor was develobed to 1) provide accurate quantification of limb activity during long-term use, 2) adhere to the necessary criteria mentioned above, and 3) overcome deficiencies of previously developed monitors.
