“…However, other authors stated that ESWT is effective in patients with non-calcified insertional Achilles tendinopathy while other cases with insertional tendinopathy who are not improving on conservative therapy will need removal of the degenerated part of the calcified tendon [25]. The protocols for ESWT are variably in different studies, ranging from either single session [9], 3-4 sessions [26], weekly or twice weekly [27,28], with either focused [7,23,26,27,[29][30][31] or radial applications [9,10,28,32,33]. The number of pulses usually ranges from 1500 to 3000 [28,31,32]; our study protocol for ESWT consisted of four weekly sessions of high energy both focused and radial technique, which was similar to other authors [10].…”
