What is a sportneer massage gun

Technically called a 'sportneer massage gun', the massage gun, which can look a bit like an electric drill with different foam heads that are placed where the drill would go.
The head oscillates back and forth, imparting a vibratory force to the skin, muscle tissue, tendons, ligaments, and fascia, causing the muscles to ripple like waves, which is not only fun but also feels like very well, as anyone who has tried it can attest.
The promised benefits include increased blood circulation, injury prevention, and pain relief.
The power of sports stars like Irving and Russel Westbrook and the growing interest in recovery from workouts have made percussion therapy devices the fitness tool of the moment.
What does science say about it?
Various reviews on vibration therapy indicate that:
muscle massage gun provide anabolic mechanical signals to the bones and the muscle-tendon system. They mimic the movement and have a positive influence on muscle function and coordination. Although there is no universal consensus on the ideal protocol to adopt, the transmission of low amplitude and high-intensity mechanical signals mimics the physiological stimuli faced by the human body in everyday life. This would ensure safety effects comparable to those of light exercise programs. »

Another subsequent analysis with 42 scientific references on vibration therapy concluded in 2014 that “the mechanical oscillatory movement provided by vibration therapy could be an effective intervention to improve the neuromuscular performance of athletes and potential hormonal responses, resulting in pain reduction and potentially lymphatic drainage '.

Finally, it is proven that there is a very interesting neurological effect on flexibility just after applying a massage with the gun.

Opinion on sportneer massage gun 
As physical therapists, what we like least about massage guns is that they are sold with all sorts of purported benefits - eg, 'stimulates muscle recovery', 'improves performance' - which are over the top at best, and delusional at worst. It is a market governed by marketing and not by science.

On the other hand, the biggest claim of muscle massage gun is their ability to relieve sore or tight muscles from training or being on your feet all day. This does have a neurophysiological basis, since muscle relaxation, according to the theory, can be facilitated by a process called autogenous inhibition.

When the body's receptors sense a vibratory force, the muscle spindle contracts (but not for long). Other sensory receptors in the muscle, called the Golgi tendon organs, immediately sense tension and cause the muscle spindle to relax into the contracted muscle.

Many experts speak of a natural transition from tension to relaxation occurs after about 30 seconds.

If we had to buy a muscle massage gun ...
We see them in gyms, Crossfit workouts or physical therapy clinics. We have already talked about its positive effects, now comes the second part and that is that you do not know which one to choose among so many advertising and models on the market.

To make your task easier, we have selected 3 massage guns that are succeeding in 2021. Click on the images for more information.
Injuries in which the use of vibration could be interesting
We have seen many cases with loss of mobility in the shoulder (for example frozen shoulder ) where a clear modification of symptoms is seen. But why does this happen?

Our brain detects overstretching and actively prevents us from going further than it thinks we should. The vibration probably interferes with that information circuit, "confusing" the brain about what is the acceptable level of stretch. And if he can interfere there, he might be able to free a very inhibited shoulder.

Even if it's only a temporary and minor effect, it would still be an extremely useful way to facilitate range-of-motion exercises. Our advice is to integrate vibration into your rehabilitation plan, using it as a way to improve mobility.

Other conditions in which movement dysfunction could be an important factor, and therefore could improve thanks to the vibration would be:

Low back pain and neck pain
Muscle tension
Tennis elbow
Contraindications
In 2020, the journal Physical Therapy published a case study of a woman hospitalized with severe rhabdomyolysis from overuse of a massage gun on her legs.

He developed severe bruises, and had so much myoglobin in his blood that he could barely urinate. It was a life-threatening emergency. It is likely that he had a certain biological vulnerability and that his muscles were more "fragile" than those of others, but that does not mean that we should pay attention to the intense use of a therapy gun
