The patient's vibration sensation can be objectively measured by means of the scaling on the back of the dampers. Due to its removable dampers, it can produce two frequencies - c128 and c64 Hz. There is no difference in diagnostic accuracy between the Rydel-Seiffer tuning fork and conventional tuning fork for detecting sensory axonal neuropathies however, the Rydel-Seiffer is easier to use and may be superior for longitudinal assessments. The Rydel-Seiffer tuning fork for neurologists from KaWe can be used to detect early damage to the nervous system or even hearing damage. The extended McNemar test showed no significant difference in sensitivity or specificity between the 2 tuning forks (χ = 1.695 P = 0.43). To obtain the fork’s frequency, hold the foot and strike the prongs on a hard surface. For the best results, each fork has two prongs, a shoulder, a stem and a foot. For example, it tests hearing loss and neurological functions. The sensitivity and specificity of the Rydel-Seiffer tuning fork to detect axonal neuropathy was 26% and 89%, respectively, and the sensitivity and specificity of the conventional 128-Hz tuning fork to detect axonal neuropathy was 20% and 88%, respectively. SURTEX Rydel-Seiffert Tuning Fork is a multipurpose tool that assists otologists to examine the ear. Published normative data were used to determine abnormal scores for the Rydel-Seiffer tuning fork and the qualitative tuning fork axonal neuropathy was determined based on sensory nerve action potential amplitudes as per our electromyography laboratory standards.Ī total of 186 sensory nerves from 100 patients were tested with tuning forks and nerve conduction studies. Study personnel who were blinded to results of nerve conduction studies collected data on vibratory perception with both tuning forks at bilateral (1) great toe and (2) distal interphalangeal joint on the second digit. Rydel-Seiffer AB-125 tuning fork for use in neurology. One hundred consecutive patients seen at the Neurology Outpatient Electromyography clinic at a major academic center were recruited and consented for this study. Rydel Seiffer tuning fork, C 64 Hz / C 128 Hz, removable dampers, with base, Nickel-plated steel, material thickness 6 mm. 25. To assess the diagnostic accuracy of the Rydel-Seiffer tuning fork versus the qualitative 128-Hz tuning fork for detecting sensory axonal neuropathy.
