Measuring hand-arm steadiness for post-stroke and Parkinson's Disease patients using SIERRA framework

In this paper, we highlight the problem of measuring hand steadiness for the patients with Parkinson's Disease or those who need a rehabilitation program such as brain post-stroke patients. Using the accelerometer, we measure the accelerations against both the body motion and gravity, which is very useful for measuring postural orientations and body movement. In this paper, we present another method for hand steadiness measurement using three-axis accelerometer. A framework named SIERRRA is developed for this purpose to obtain and evaluate the hand reach movements.
