Sir, in recent times, there has been an increase in percussion therapy massage devices on the market. This involves rapid vibrations and pulsing movements penetrating overworked muscles after workouts; however, there is currently very little scientific evidence on their effectiveness.1
The COVID-19 pandemic has been incredibly tough for everyone; adults have had less social interaction, more people are working from home, children have uncertain and confusing futures. This period has led to diminished dental health leading to TMD, bruxism and myofascial pain.2 Current treatment involves painkillers, soft occlusal bite guards and relaxation techniques. We question whether percussion therapy could be used to soothe the muscular pain in the head and neck. Evidence from 20 years ago suggested excellent results in the management of facial pain.3
For obvious reasons, one would not normally suggest applying repetitive forces anywhere near the cranial region; however, many of these devices allow softer attachments, reduced vibrations and lighter force which could be altered for treatment of the muscle of mastication. As with any medical device, appropriate instructions would need to be provided to patients to ensure they are using the device correctly, and are aware of the potential side effects of failing to follow guidance. Although rare, serious complications have been associated with these devices.4
