Massage guns are marketed a wonder tool you can use to do self massage and help recover after a workout, but when we investigated we found that the marketing claims were dubious and deceptive, and many machines were massively overpriced for what they are.

Professionals have been using therapeutic vibration for decades. The vibration massagers they use have a vibrating pad that sits on the surface and sends in vibrations. Massage gun marketers have modified these machines so they drive their heads in, claiming that that this increases penetration and adds the benefits of conventional massage. However, as we will discuss doing this reduces the amount of effective vibration while increasing the risk of doing harm and adding very little. The easiest way to understand this is by looking at the picture below.
If we look at this diagram the machine on the left is a vibration massager. As you can see it has a vibration pad designed to send large amounts of vibration deep into your muscles. The tool on the right is a t-bar, which massage therapists use these to save their thumbs and to apply deep (painful) pressure.
As you can see the massage gun in the middle is basically a t-bar with a jack-hammer mechanism. Compared with the vibration massager the head of the massage gun goes up and down a lot more, and is designed to drive into the muscle rather than send in vibrations.
Massage gun marketers claim that their machines give you the benefits of a vibration massager, but by driving their head in it increases penetration and adds the benefits of conventional massage. Let us look at each of these claims.
As discussed in our article The scientifically proven effects of vibration massage- with clinical applications, therapeutic vibrations do have excellent benefits. However, massage guns:
As you can see from the diagram above massage guns are designed to drive their heads in like jackhammers rather than send vibrations deep into your muscles. Because of this massage guns do not deliver anywhere near the amount of vibrations a proper machine does.
As discussed in our article The scientifically proven effects of vibration massage- with clinical applications, to have the therapeutic effects the vibration frequency should be between 30-60 hz (cycles per second), with about 50 being optimum. Most massage guns come with hard plastic heads while powerful machines drive their heads in 14-16mm. Driving something 16 mm into your muscles 50 times a second would cause tremendous damage so Theraguns are limited to 40 hz, but even that is way too fast because a survey of professionals found that most used their massage guns on “”slow” or “medium” (4). At these speed any vibrations are way outside the therapeutic range.
Massage gun marketers will tell tell you that driving the head in increases penetration. While they do drive their heads in it is the vibrations rather than the head penetration that has the therapeutic effects, and vibrations penetrate much further. That is why with their head just sitting on the surface ultrasound units (vibrations at a different frequency) can penetrate deeply for therapy and imaging. If you've ever used a genuine vibration massager you’ll know that the vibrations can go right through you.
While massage gun marketers claim their machines add the benefit of conventional massage we know of no study or trial that actually shows this. The only scientifically proven benefits massage gun marketers discuss are those of therapeutic vibration, which as we have discussed massage guns give very little.
Realistically the only thing driving the head in does is potentially hurt you. What will happen if you drive one of the hard plastic jackhammer heads into a nerve or blood vessel? Even using a percussion massager on muscles is not safe. There’s a journal report of someone nearly dying from internal bleeding after using one to help recover after a bike ride (2). Another report discusses a massage gun user who suffered hemothorax (bleeding in the lung cavity). This condition is usually associated with blunt force trauma (5).
The most damning opinion of massage guns actually comes from those scientists massage gun advocates get to conduct clinical trials. Marketers tell you that it it a wonderful idea to have hard plastic heads and machines that drive into your muscles up to 16 mm. However, to get some benefits and not hurt the patients when scientists conduct trials they do the opposite (1,3). As an example, as the excerpt from the journal report below shows the scientists used a damper attachment. These spread the contact out and reduce the amount the contact goes up and down.
Of course this gets buried in the fine print and you are mislead that the massage guns were used as the marketers advocate.
Some massagers have a powerful jackhammer mechanism that drive their heads in 16mm. Because of this a colleague told me that that she could only use hers on slow speed, otherwise it would hurt her patients. As discussed above, to get he the proper therapeutic effects vibrations need from 30-60 Hz with the optimum being approximately 50 Hz. My colleague could not use her Theragun at anywhere near that speed because it would hurt her patients.
Massage guns are designed to be pointed into your muscles. As we can see from this diagram unless you have unusually long and bendy arms you will not be able to reach a lot of your body.
The word "gun" and the distinctive shape are a great marketing gimmick, but you need to ask yourself "would the manufacturer of a serious therapeutic device make one that you could not use effectively on a large portion of your body?"
Massage guns have a similar mechanism to that found in a jigsaw or reciprocating saw. The later are used in rough conditions and need to be strong enough to cut things like metal, therefore trades person versions of these tool are likely to be more robust and durable. Why then to “top massage guns” cost much more than a high quality trades person’s power tool?
The simple reason massage guns are so expensive is that the marketers spend a fortune to convince you that they are a good idea, and if you are mislead you end up paying for it.
A colleague who works for the ATP (Association of Tennis Professionals) wanted to use a genuine vibration massager rather than a massage gun. He was not allowed because Theragun had paid the ATP huge amounts of money for their endorsement.
So, hopefully you now understand that while massage guns claim to combine the benefits of conventional and vibration massage the reality is that they do neither well and are more likely to hurt you. You are best to stick to either genuine vibration or conventional massage. If you want the hand held device you can use yourself that will need to be a genuine vibration massager. Please see our article How to choose a massager
That said, as discussed in our article Why most massagers are a waste of money serious personal therapeutic vibration massagers are not that common. Most genuine vibration massagers are made for professionals to use on their patients, not personal use. Because of this, to get something decent for our patients we built our own.
This is our General Purpose Massager. The business end delivers copious amounts of therapeutic vibrations. Over the years we’ve sold over 100,000 of these without any advertising, mainly though professionals like chiropractors, osteopaths and physical therapists using them and recommending them to their patients.
More recently we’ve developed our quad head machine that has all the good things the General Purpose Massager has, but can do a much greater area at once and because the front part is larger and flatter you can easily use it like a cushion or chair massager.
