Achilles tendinopathies are challenging to treat due to the presence of chronic inflammation and poor vascularization. Cases of acute and chronic Achilles tendinopathies experience some form of a chronic inflammatory profile. As a result, therapies that target and reduce inflammation are beneficial in both cases. The cellular basis for inflammation lies in the improper function of ion channels within cell membranes, resulting in altered cation flow and cell function. To reduce ion channelopathy, an Electron Modulation Device (EMD) has been developed that delivers multi-channelled vectored and triangulated electron energy to affected areas. EMD therapy can reduce the free radical formation and correct molecular isometric structure, thus improving cell membrane and ion channel function. This reversal in ion channelopathy can lead to a decrease in chronic inflammation and pain. The benefits of modulated electron energy were tested in the case of a 21-year old college football player presenting with bilateral Achilles tendonitis who underwent twelve treatments over eight weeks while continually practicing with little rest. The subject’s pain level was assessed via a visual analogue scale (VAS) 0-10 Numeric Rating Scale before and after treatment. After every treatment session, the patient recorded a pain score of 0, indicating no pain, for his left Achilles tendon while also noting improved mobility and reduced inflammation. The therapeutic benefits of EMD are attractive as the ability to rapidly reduce pain and inflammation can promote healing, thus effectively managing sports-related injuries or musculoskeletal dysfunctions without the use of opioids or opiates and the risk of addiction.
