Abstract:
1. A compact diagnostic neurological tool comprising: (a) a variable two-point discriminator; (b) a brush; and (c) a sharp-dull instrument having a fine with a pointed end and a fine with a blunt end, wherein the tines are at a constant distance from one another; wherein the variable two-point discriminator, the brush, and the sharp-dull instrument are all housed within a single case; wherein the variable two-point discriminator, the brush, and the sharp-dull instrument may be retracted so that they are fully enclosed by the case or extended so that they extend outside of the case; wherein the variable two-point discriminator comprises two tines with distal ends, and wherein the distance between the distal ends of the fines can be increased by the user by pushing a thumb grip upward to extend the two-point discriminator outward from the case and decreased by the user by moving the thumb grip downward to retract the two-point discriminator into the case, and wherein a scale situated adjacent to the thumb grip corresponds to the distance between the distal ends of the tines; and wherein neither the variable two-point discriminator, the brush, nor the sharp-dull instrument is removable from the case, the two-point discriminator, the brush, the sharp-dull instrument, and a Whartenberg wheel are all fully enclosed within the case when not in use, and the variable two-point discriminator, the brush, and the sharp-dull instrument are used without being removed from the case.
