Biothesiometry Vibrotest is a useful non-invasive tool for the detection of subclinical neuropathy in children and adolescents The Biothesiometer Vibrotest is used as a research device in many neurological diseases. It is essentially an "electronic tuning fork" whose vibration strength may be gradually increased until the threshold of vibratory sensation is felt by the subject. Alternatively, the vibration strength may be lowered until the vibration is no longer discernible. In all cases, the vibration strength amplitude may be determined with a high degree of accuracy.
The Vibrotest is not only far superior to a tuning fork in accuracy but will detect neurological changes that are not disclosed with a tuning fork. It is also quantitative.
