Sensory evaluators
These portable sensory evaluators are manufactured within a 5% standard deviation of each target force.
Use to test sensory levels and obtain objective data for accurate reporting on the status of diminishing or returning sensibility.

These portable sensory evaluators are manufactured within a 5% standard deviation of each target force.
- Use to test sensory levels and obtain objective data for accurate reporting on the status of diminishing or returning sensibility.
- The filament bends when peak force threshold is reached.
- The unique handle easily opens to a 90° angle for testing. When closed, the Sensory Evaluator can be carried safely in a pocket or carrying case, protecting the filament when not in use.
- Finger indentations on the handle provide a firm, comfortable hold.
- The Sensory Evaluator handles are marked with the corresponding color-coded pressure level.
- Individual replacement Sensory Evaluators are sold separately, including the 5.07, which indicates loss of protective sensation for foot.
- Available in a 5 Piece Hand Kit, a 6 Piece Foot Kit and a 20 Piece Full Kit.
- Each kit comes in a protective case. Instructions are included.
- Free journal articles are available.
Evaluation results can be recorded on the Hand Screening Forms or Foot Screening Forms.
A History of Monofilaments
In 1960 Josephine Semmes and Sidney Weinstein developed the modern monofilament. Later, the levels of force applied by different monofilaments were correlated to levels of decreased sensory function. In 1987, The Journal of Hand Surgery published “The Repeatability of Testing with Semmes-Weinstein Monofilaments” by Judith Bell-Krotoski and Elizabeth Tomancik of the Gillis W. Long Hansen’s Disease Center. This study validates the use of Semmes-Weinstein monofilaments as a repeatable and reliable test of sensibility. The study concludes that “the filaments are a controlled, objective, reproducible force stimulus available for use in clinical testing of peripheral nerve function,” (161).
