Microvibrational techniques
The brain can only process a limited amount of sensory information at once. By introducing a competing sensation, vibration can reduce the perception of discomfort.
Micro-vibrational technology is based on a simple but powerful principle: the brain can only process a limited amount of sensory information at once. By introducing a competing sensation, such as gentle vibration, it can reduce the perception of discomfort. These devices are typically placed near the site of an injection or treatment and produce a mild, continuous vibration.
This effect is supported by what is known as the “gate control theory” of pain, where non-painful stimuli can interfere with the transmission of pain signals. For patients who are particularly sensitive to injections or certain sensations, this can be a valuable tool.
Example:
During an injection, instead of focusing on the needle, the brain becomes more aware of the vibration. As a result, the sensation of the injection is reduced or even barely noticed.
The vibration itself is not uncomfortable, most people describe it as a gentle buzzing or massaging feeling. It can also create a sense of distraction, similar to other techniques, but with a more direct physiological effect.
Micro-vibrational techniques are often used in combination with:
Topical anaesthetic
Slow anaesthetic delivery
Clear communication
Together, these approaches create a layered strategy that significantly reduces discomfort.
While not every patient will notice a dramatic difference, many find that it takes the “edge” off the experience, making it feel less intense and more manageable.
