To test vibration sense, the examiner places a finger under the patient’s distal interphalangeal joint and presses a lightly tapped 128-cycle tuning fork on top of the joint. The patient should note the end of vibration about the same time as the examiner, who feels it through the patient’s joint.

2024年12月12日 · vibration sense is particularly important in patients with sensory symptoms, such as numbness or tingling, or in any patient being assessed for the possibility of a peripheral nerve or spinal cord

It is instructive to test vibration sensation of the toe of a person with an artificial limb. Vibratory stimuli, transmitted through the artificial limb, are felt in the thigh stump. The tuning fork is the device most commonly used to assess vibration sensation.

2018年2月17日 · The 64 Hz Rydel-Seiffer tuning fork (RSTF) provides a more quantitative assessment of vibratory sensation. There is a black and white display of two arrows and two sets of numbers from 2 to 8 (Figure).

There are five primary sensory modalities typically tested in a routine neurological examination. 1 Three of these, vibration, joint position sense and pinprick, are the focus of this discussion. Light touch and temperature are discussed, but not described in detail.

Vibration is tested by sensation of a tuning fork held on a bony prominence. Testing should be done initially distally, as shown on the great toe. If there is decreased sensation distally, testing should also be done proximally, to determine the extent of the deficit.

Quantitative sensory testing (QST) is a systematic psychophysical test method used to measure sensory thresholds for pain, touch, vibration, and temperature sensations. It quantifies individual sensory perceptions using direct patient feedback.

The sensory exam involves evaluation of pain (or temperature), light touch, position sense, vibration, and discriminative sensations. This portion of the exam is very subjective, and may become unreliable if repeated in quick succession.

An essential part of the screening, diagnosis and follow‐up evaluation of polyneuropathy is the assessment of sensory function, including vibratory sensation. Vibration and pinprick sensation along with ankle reflexes were found to be the most sensitive measures of polyneuropathy in clinical testing (Abraham et al., 2017), whereas both ankle ...

Vibration is a very useful perception to test as it addresses the smallest of the peripheral nerve fibres (type C) which have long been regarded as the hallmark for early sensory loss. A 128 Hz tuning fork provides the required frequency. A Rydel Seiffer tuning fork enables the frequency at which vibration perception is lost to be quantified.
