Since it is well documented that both pain and inactivity reduce muscle force and normal activation patterns, we believe that treatment approaches should initially focus on optimizing the latter. The problem is that pain often makes it difficult or impossible to exercise patients to improve strength, power and endurance. However, we often see significant pain reduction after a single Neurac treatment session, especially when applying vibration using the Redcord Stimula. In many cases this enables patients to perform regular exercise immediately after such a treatment, and thereby have the opportunity to improve strength, power and endurance. But how do we explain this?
