VibraTip Vibration Sense Testing Device
VibraTip is a wipe-clean, disposable, key fob-sized device that provides a constant and reproducible source of vibration, designed specifically to test vibration sense in diabetes patients.
VibraTip can be applied to the skin more gently, more discretely, more consistently, more hygienically and more rapidly than a tuning fork. Vibration stimulus from VibraTip extends further than point pressure and is less affected by local skin characteristics such as the presence of callus. The spherical head facilitates application from any angle and its pocket size means that it is easy to carry and therefore likely to be available at the point of use.
By gently touching the patient’s intact skin twice with the rounded tip of VibraTip, each time for about half a second, explaining that 'this is touch one' and 'this is touch two' whilst randomly activating VibraTip on either the first or second touch, a sensitive and specific assessment of vibration perception is obtained.
A prospective trial of 100 consecutive patients showed that VibraTip was as effective at detecting neuropathy as a tuning fork or monofilament.
The VibraClip is a re-usable lanyard that will ensure that the VibraTip is kept within easy reach. It features a secure magnetic attachment mechanism that allows the VibraTip to be removed quickly for use.

Application
- Hold VibraTip gently between thumb and index finger
- Gently touch the patient’s intact skin twice, each time for about 1 second, with the rounded tip of VibraTip, explaining that 'this is touch one' and 'this is touch two'
- Randomly activate VibraTip on either the first or second touch
- Ask the patient which of the two touches was associated with vibration
- Clean VibraTip between uses with an alcohol swab
Precautions
- VibraTip should only be applied to intact skin
- VibraTip should not be applied to mucosal surfaces
- VibraTip should not be inserted into the urethra, ear or other body cavities
- VibraTip should be kept away from the eye
- Do not allow alcohol from cleaning swabs or other liquids to seep into the battery compartment of VibraTip
- Do not immerse VibraTip into liquid at any time as permanent damage is likely to result
