Hartmann Tunning Fork C 128

Clinical Application

This 128 Hz tuning fork is used for bedside and perioperative sensory assessment. It is optimized for testing vibratory perception in neurology and peripheral neuropathy screening (diabetic, alcoholic, and compressive neuropathies), and for basic otologic assessments such as Rinne and Weber tests to evaluate bone conduction. In perioperative settings it can aid rapid neurosensory checks and confirm return of vibratory sensation following regional anesthesia or nerve repair procedures.

Design & Configuration

The two-pronged U-shaped geometry produces a clear, sustained vibration at 128 Hz when struck, a frequency well-suited to clinical testing of peripheral vibration sense. The rigid stem provides a secure point for striking and precise placement against bony landmarks (e.g., medial malleolus, distal phalanx, mastoid), enabling reproducible contact and reliable bedside comparisons. The simple, single-piece form factor minimizes damping and facilitates fast, repeatable examinations.
