Abstract
An average coefficient of static friction between skin and paper is determined based on pinch-strength measurements and a corresponding maximum weight of bucket and water before slippage occurs. With the coefficient of static friction determined, a pinch-strength threshold for impairment uniquely determines the threshold for a weight of a pinch test apparatus using one or more common or household material(s), such as bucket and water. A patient using such apparatus at home can therefore put sufficient water in the bucket to reach this weight and see if they can lift the bucket or not, thereby determining whether or not impairment exists.
