Vibrameter
(Type 1V Somedic)
Vibration is thought to be one of the first sensations to be lost following neuropathy. Vibration is propagated along the large diameter afferent nerves (the A beta nerves). These large diameter nerves are most vulnerable to the effects of ischaemia than other sensory nerves. It has been shown that vibration thresholds may be altered when other nerve conduction tests have been found to be negative, making this equipment an ideal tool to use in early signs of nerve damage. It has been repeatedly used in patients with work related upper limb disorder (previously termed RSI), but could be used when any neuropathy is suspected.
