Yes. Apollo Neuro programs deliver gentle vibration. Studies of numerous forms of vibration demonstrate no significant negative reactions from routine use. Vibration at Apollo Neuro's decibel levels have not been found to pose risk of harm.
We recommend not applying Apollo to a site of injury. If you have a limb (arm or leg) or irritated area of skin that is recovering from an injury, we recommend applying Apollo to a different place on your body.
