Abstract
This paper describes a hand test consisting of three steps to test the subject's ability to grasp firmly another person's hand to hold a pencil firmly with fingers II-V with straight knuckles and maximally flexed finger joints, while the investigator pulls the pencil to hold on to a piece of paper with a rounded pinch grip between thumb and index finger while the investigator pulls the paper with a rounded pinch grip with submaximal strength. All three steps must be performed with each hand without causing pain. The test was an adequate parameter for the grip function, and at the same time could register work-load elicited pain, strength, and mobility. The test can be carried out by healthy subjects, but not by patients with rheumatoid arthritis. The test is logically constructed and has a high validity and reliability.
