Determination of Forces and Moments of Hand Joints for Designing a Rehabilitation Device

Rehabilitation devices are used for hand rehabilitation in patients with finger paralysis, which happens as a consequence of stroke. The most commonly used rehabilitation procedure usually involves movements of flexion and extension of fingers. When designing rehabilitation devices, it is possible to analyse, at an early stage, using a computer model, the device characteristics, and efficiency of interaction of the device and the body part that is in need for rehabilitation. The aim of the research was to develop a mathematical model of a human hand describing flexural and extensional motion and behaviour of the hand while interacting with a rehabilitation device. Kinematic data was determined by measurement in a biomechanical laboratory. Moments in the hand joints were calculated and used as indicators of activity of individual muscles. The proposed mathematical model provided an analysis of the characteristics of the future rehabilitation device.
