FIELD: measurement technology.
SUBSTANCE: invention relates to medical equipment. Device for measurement of kinetic and force parameters of hand includes support element (8) in the form of two semicylindrical cross-beams and force sensor. Cross-beam diameter can be changed by installation and removal of replaceable trims in the form of hollow wooden semi-cylinders. Force sensor (14) is made in the form of elastic element with resistance strain gauges combined in two bridge schemes linked to measurement system. Device includes base (1) with attached elbow fixation unit and measurement unit. Measurement unit includes vertical frame (5) mounted on joints and rotating around vertical axis, with joint connection to horizontal frame (6) rotating around longitudinal axis, with counterweights (13) and axle (9) bearing work frame (7) of hand grip with support element, rotating around horizontal axis. Each frame is equipped with rotation angle sensor (10-12). Measurement system includes control unit.
EFFECT: extended functional capabilities and enhanced accuracy of dynamometric measurement.
