Sensory Testings

Tactile Sensation

Common neuropathy (diabetes to lacerations)

Monofilament esthesiometry is used to determine tactile sensation.  The Semmes-Weinstein Monofilaments was the typical instrument employed.  An enhancement to these monofilaments was also created by Weinstein -- Weinstein Enhanced Sensory Test (WEST).  Affordable subsets may be purchased from medical distributors in the USA.  Two popular sets of forces are presented in the WEST-hand and the WEST-foot.  The WEST uses "Softip" monofilaments, which provide a more consistent "touch" stimulus.
