Abstract: A disposable neurological tester comprising a many-pointed pinwheel having a hub and an annular radially projecting array of synthetic organic plastic tines for neurological testing stimulation of the skin and flexible against skin penetration, and an elongated synthetic organic plastic handle having a first terminus. The pin wheel is carried at the handle first terminus on an axle supported from a single side with the tines projecting for skin stimulation, whereby precise locus of skin stimulation by said wheel is viewable by the tester operator from the side of the pin wheel which is free of handle support.
