Clinical and Ultrasonographic Results of Intratissue Percutaneous Electrolysis in Lateral Epicondylitis

"* The EPI technique was performed under ultrasound-guidance on the clinically relevant area (or areas of maximum tenderness to palpation and with ultrasonographic degenerative tendon changes) using an intensity of 4-6 mA during 3 seconds, approximately 3 times. We used the EPI machine (Cesmar Electromedicina S.L., Barcelona, Spain) and a GE Logiq E Portable Ultrasound Machine with GE Linear probe 12L-RS (5-13 mhz) (GE Healthcare, Wisconsin, EEUU).~* The eccentric exercise program consisted of three series of up to 10 repetitions of eccentric work, repeated twice daily (morning and afternoon), under maximum load (initially with one kilogram) in an optimal and functional pain-free range.~* The stretching program consisted of a stretching exercise for the epicondylar muscles consisting in three series of 7 repetitions twice a day (morning and afternoon."
