A hand held point stimulator device is a very useful tool which may be used when needling in the treatment of musculoskeletal pain syndromes - mainly for the deactivation of trigger points (TrP). It may be tolerated better with less treatment soreness as opposed to a more conventional dry needling technique, this is certainly the case from my own clinical experience with the device. The lack of evidence for efficacy is due to the fact that to my knowledge no trials have been performed to date, however we may be guided by the current evidence we have supporting the use of needling for myofascial pain syndrome for example. Clinically we have very good evidence to suggest a handheld point stimulator is an extremely effective way of comfortably augmenting the needle effect.
Is a versatile hand held electro-stimulatory device and can also be used to locate areas of decreased skin resistance thought to correspond with traditional acupuncture points.
