What is ISO 13091‑2 about?
ISO 13091‑2 is second in the series of documents on mechanical vibrations. ISO 13091‑2 specifies methods and procedures for analysing and interpreting vibrotactile perception thresholds and threshold shifts. Procedures for describing statistically significant changes in vibrotactile perception thresholds are recommended.
ISO 13091‑2 is applicable to vibrotactile perception thresholds determined at the fingertips according to the provisions of ISO 13091-1.
Who is ISO 13091‑2 for?
ISO 13091‑2 on mechanical vibrations is useful for:
- Neurologists
- Diagnostic testing centres
- Neurosurgeons
- Physical therapists
Why should you use ISO 13091‑2?
Early detection of peripheral neuropathies in the upper extremities, which are often manifest as changes in tactile function and hence changes in mechanoreceptor acuity, is of considerable interest. Such neuropathies can occur because of disease, or of exposure to chemical or physical, neurotoxic agents.
ISO 13091‑2 helps users by specifying analysis, interpretations, and procedures for describing statistically significant changes in vibrotactile perception thresholds are provided for the situation in which the threshold is determined on a single occasion, as well as when the threshold is determined repeatedly.
Overall, ISO 130912 offers procedures, test methods that help identify neuropathy or other nerve disorders at an early stage so that they can be treated in time, saving human life, in the event of a critical condition.
What is changed since the last update?
BS ISO 13091‑2:2021 supersedes ISO 13091-2:2003. BS ISO 13091‑2:2021 includes some technical changes with respect to ISO 13091-2:2003. These include:
- The contents of Annex A have been updated to include studies of the vibrotactile perception thresholds of healthy persons published since the first edition of the standard
- The Bibliography has been updated to include the studies listed in Annex A
