Mechanical vibration. Vibrotactile perception thresholds for the assessment of nerve dysfunction. Methods of measurement at the fingertips | Status: Current

1 Scope This part of ISO 13091 specifies

• — methods for measuring vibrotactile perception thresholds (VPTs) at the fingertips,
• — procedures for conducting the measurements, and
• — the reporting of results.

Measurement methods are defined in this part of ISO 13091 for obtaining perception thresholds at the fingertips mediated, separately, by SAI, FAI and FAII mechanoreceptor populations. The methods are designed to be applicable to healthy and diseased persons, and to be suitable for clinical assessment and for screening purposes. The measurement of temporary shifts in vibrotactile perception threshold, or of thresholds at body sites other than the fingertip, is outside the scope of this part of ISO 13091.
