Effectiveness of Extracorporeal Shockwave Therapy Based on Fascial Manipulation Theory for Lateral Epicondylitis

ESWT was performed using the Swiss DolorClast Master ESWT device in accordance with the guidelines of the International Society of Medical Shockwave Therapy. The treatment was carried out by a physical therapist with at least 5 years of ESWT experience. The patient sat with the shoulder abducted at 45°, the elbow flexed at 90°, and the forearm supinated. The shock waves were delivered in a circular motion, targeting the 2-3 most painful tender points within a 3 cm radius centered on the lateral epicondyle. A total of 2,500 pulses were administered per session (0.2 to 2 bar, 8 Hz, 2,500 pulses, with intensity adjusted according to the patient's tolerance). All patients received a total of 4 ESWT sessions, once every 5 days, over a period of 3 weeks.

The assessment was conducted by a 5-year or more experienced FM therapist, following the standard procedure of the FM organization. The process included conducting interviews, filling out assessment forms, performing movement checks, and conducting palpation. Four CC points covering the entire upper limb, including the shoulder area, were selected. The points were ranked based on the severity of the dense touch. The blackboard pen was used to mark the points on the patient's body. The same ESWT therapist as in Group A used the same shock wave treatment instrument to treat the four CC points. The most severe point received 800 shocks, the second most received 700 shocks, and the remaining two points each received 500 shocks. A total of 2,500 pulses (with an intensity of 0.2 to 2 bar, a frequency of 8 Hz, and the intensity adjusted according to the depth of the point and the patient's tolerance) were administered. This treatment was performed once every 5 days for 3 weeks.

Carry out the same process as Group B, but only select the three most severe CC points for shock therapy. Also, rank them according to the severity of the touch examination-induced densification. The most severe point receives 600 pulses, the second most severe receives 500 pulses, and the third most severe receives 400 pulses. At the same time, treat the lateral epicondylitis pain area in the same way as Group A. Apply 1000 pulses to the pain area. The total number of shocks for all treatments is 2500 (with an intensity of 0.2 to 2 bar, a frequency of 8 Hz, and the intensity is adjusted according to the depth of the point and the patient's tolerance). The therapist performing the treatment is the same as those in Group A and Group B. The treatment is carried out once every 5 days for 3 weeks.
