Shock Wave Therapy Versus Progressive Pressure Release on Myofascial Trigger Points

Abstract

Background

Efficacy of Extracorporeal Shockwave therapy on pain and function in Myofascial Pain Syndrome: A systematic review and meta-analysis of randomized clinical trials

“…In terms of the treated area, 22 studies were carried out on patients with cervical and shoulder complaints, three studies were conducted on the leg/foot region, 25,27,28 and two trials were conducted on the lumbar spine region. 22,30 On the duration of pain, eight studies reported no data on this variable, 19,20,23,28,32,33,38 five studies reported between zero days and 3 mos of pain duration, 18,24,29,33,34 and 14 studies reported that their sample had a duration of pain longer than 3 mos.…”

“…The characteristics of the included studies are shown in Supplementary Appendix 2 (Supplemental Digital Content 3, http://links.lww.com/PHM/C68). Of the 27 RCTs included, 12 compared ESWT against a control ESWT, [17][18][19][20][21][22][23][24][25][26][27][28] and 18 compared ESWT, [17][18][19][20][21][22]26,[29][30][31][32][33][34][35][36][37][38][39] with other interventions. Most of the trials included two arms, except for six trials, which were three-armed studies.…”

“…The protocols and parameters for the application of ESWT were heterogeneous. Eighteen studies used radial ESWT, [17][18][19][20][21]26,[28][29][30][31][33][34][35][36][37][38][39] with a dose range of 1.2 to 4 bar or 0.056 to 0.2 mJ/mm 2 ; the number of pulses applied to the TPs ranged between 300 and 1500, and the frequency ranged from 1 to 20 Hz. On the other hand, nine trials used focused ESWT, 19,[22][23][24][25]27,[32][33][34] with a dose range of 0.056 to 0.26 mJ/mm 2 ; the number of pulses applied to the TPs ranged between 400 and 700, and the frequency ranged from 1 to 10 Hz.…”

“…Eighteen studies used radial ESWT, [17][18][19][20][21]26,[28][29][30][31][33][34][35][36][37][38][39] with a dose range of 1.2 to 4 bar or 0.056 to 0.2 mJ/mm 2 ; the number of pulses applied to the TPs ranged between 300 and 1500, and the frequency ranged from 1 to 20 Hz. On the other hand, nine trials used focused ESWT, 19,[22][23][24][25]27,[32][33][34] with a dose range of 0.056 to 0.26 mJ/mm 2 ; the number of pulses applied to the TPs ranged between 400 and 700, and the frequency ranged from 1 to 10 Hz. The participants received one to three weekly ESWT sessions, and the total number of ESWT sessions in most studies was between three and four, except for the following trials: the trial of Toghtamesh et al 34 received one session, that of Eftekharsadat et al 20 received five sessions, that of Gezgİnaslan et al 21 received seven sessions, that of Cho et al 31 received 12 sessions, and that of Huang et al 39 received 24 sessions.…”

“…In terms of the participants' gender, 802 (69.49%) were women; of note, six trials did not report this information. [19][20][21][32][33][34] Their ages ranged between 18 and 70 yrs; see Supplementary Appendix 2 (Supplemental Digital Content 3, http://links.lww.com/ PHM/C68). In terms of the treated area, 22 studies were carried out on patients with cervical and shoulder complaints, three studies were conducted on the leg/foot region, 25,27,28 and two trials were conducted on the lumbar spine region.…”
