Applications for home-based care are rapidly increasing in importance due to spiraling health care and elderly care costs. An important aspect of home-based care is exercises for rehabilitation and improving general health. However, without caregivers supervising these exercises it is difficult to monitor them, i.e., to determine whether the exercises have been performed correctly and for the p...

The CourseMarker system has been used to assess free-response computer based assessment (CBA) exercises since 1998. The aim of the studies reported here was to evaluate the feasibility and usefulness of developing and deploying diagram-based exercises using DATsys, an authoring environment for diagram-based CBA, together with CourseMarker. Postgraduate students constructed diagram-based exercis...

Weakness of the hip abductors after total hip arthroplasty may result in pain and/or functional limitation. Non-weight-bearing (NWB) exercises are often performed to target the hip abductors; however, muscle activation of NWB exercises has not been compared to weight-bearing (WB) exercises. Our purpose was to evaluate gluteus medius activation during 2 WB and 2 NWB hip abductor strengthening ex...
