Alternative design of the equipment for the finger strength evaluation

摘要

Diseases, injuries, fractures, or conditions after operations on fingers and hands often cause loss of muscle strength and limit the mobility of a particular limb. Muscle strength restoration or increasing the range of motion may be achieved by the rehabilitation of the damaged area. The rehabilitation course ensures that a given area returns, in the maximum possible extent, back to the condition existing prior to the injury. To enable correct finger strength assessment or the rehabilitation success evaluation by an examining person, it was req uired to construct a device capable of measuring the strength of individual fingers. The submitted article deals with the alternative design of such device for the finger strength measurement, it describes the final design of the device and the measurement methodology that must be adhered to when assessing the muscular strength of fingers of a hand.
