Jamar Discriminator Two-Point Sensation Test Tool - Clinical Sensory

In this review of the Jamar Discriminator the verdict is straightforward: this pair of discrimination octagon tools is best for clinicians who need a simple, reliable way to measure stationary and moving two-point discrimination during rehabilitation. Physical therapists, occupational therapists and certified hand therapists will appreciate the clear range of measurements and the tactile options for single-point and double-point testing. The review focuses on usability in post operation and nerve injury cases, where accurate assessment of sensory recovery and innervation density matters most.

Key Features

• Dual tools included: The set includes two discrimination octagon tools so clinicians can test both sides or compare serial measurements without delay.
• Wide measurement range: Measures innervation density from 1 - 25mm which covers the clinical span needed for most two-point discrimination assessments.
• Stationary and moving tests: Supports both stationary and moving two-point discrimination testing to capture different sensory modalities during rehabilitation.
• Single and double point options: Allows precise switching between single point and double point stimuli for controlled nerve sensitivity evaluation.
• Clinical-grade material: Made from non-latex material appropriate for professional settings and patients with latex allergies.

Who It's For

The Jamar Discriminator is aimed at clinicians conducting sensory exams after nerve injury, tendon repair or hand surgery, as well as therapists tracking recovery over time. It is especially useful in outpatient clinics, hand therapy practices and rehabilitation units where quick, repeatable discrimination testing is required.

Therapists looking for digital recording or automated scoring should look elsewhere; this is a manual, low-technology tool meant for hands-on testing rather than electronic data capture or integration with apps.

Pros & Cons

Pros

• Simple, reliable design that clinicians can use immediately without calibration or batteries.
• Includes two tools so bilateral comparisons and frequent testing are convenient.
• Covers a practical 1 - 25mm range suitable for most clinical two-point discrimination protocols.

Cons

• Manual measurement requires the clinician to record and track results; no digital readout or automated logging is provided.

Specifications

Our Verdict

The Jamar Discriminator is a practical, low-tech tool that gives clinicians a dependable way to assess two-point discrimination and track sensory recovery after nerve injury or surgery. For therapists who value straightforward, repeatable measurements without the cost or complexity of digital systems, it represents good clinical value and fits readily into standard assessment routines.
