  • Patent number: 5904639
    Abstract: A protocol-configurable isometric hand grip recording dynamometer with user guidance. The apparatus employs a grip within which is mounted a load cell. The load cell, in turn, is coupled to a rigid printed circuit board which is compressively squeezed during an exercise regimen. A readout is integrally formed with the battery operated system to provide aural and visual cuing at an angle facilitating the user's reading of a display. Visual cues are provided at the display throughout an exercise regimen prompting the user as to which hand to use and the amount of compressive squeezing force to be applied. The system and method includes a technique for scoring the efforts of the user. The microprocessor-driven device includes archival memory and a data communications port such that may be employed interactively with a trainer or physician.
