Methods: In this randomised, double blind, placebo-controlled study, we treated 34 patients with four sessions of RSWT (once weekly) and treated 34 patients with placebo. Participants were assessed at baseline, 1 week after the first session, and 1 week and 4 weeks after the last session. We measured pain using the visual analogue scale for pain, while we assessed muscle tone using the modified Ashworth scale and evaluated spinal excitability using the H-reflex.

Results: After RSWT, muscle tone decreased 1 week after the last session and pain decreased at all the follow-up evaluations, while spinal excitability was unaffected. No significant changes were found after the placebo treatment.

Conclusions: RSWT can reduce pain and muscle tone in MS patients without adverse effects. The lack of RSWT effects on spinal excitability supports the idea that RSWT is likely to act on non-reflex hypertonia, for example reducing muscle fibrosis.

Participants:
Thirty-two field and track runners (weekly mileage: 20–40 km) with chronic ITBS (15 females, 17 males; aged 18–35) were randomly assigned using block randomization to either an active RSWT group or a sham control group

Results:
Significant time × group interactions were found for pain (VAS), knee function (KOOS), and ITB tendon thickness. The SWT group showed greater improvements than the sham-group across all outcomes. Pain scores decreased substantially (F(2,60) = 126.83, p < .001, partial η² = 0.81), indicating a very large effect size. KOOS scores improved significantly (F(2,60) = 75.59, p < .001, partial η² = 0.76), also reflecting a very large effect. ITB thickness was reduced (F(2,60) = 54.39, p < .001, partial η² = 0.65), demonstrating a large effect size.

“Plantar heel pain, a chronic and disabling foot alignment, occurs in the adult population. Extracorporal shock wave therapy (ESWT) offers a nonsurgical option in addition to stretching exercises, heel cups, NSAI, and corticosteroid injections. This study aimed to investigate the effects of ESWT on calcaneal bone spurs and the correlation between clinical outcomes and radiologic changes. The study involved 108 patients with heel pain and radiologically diagnosed heel spurs. All patients underwent ESWT once a week for 5 weeks at the clinic. Each patient received 2,000 impulses of shock waves, starting with 0.05 mJ/mm2 (1.8 bar) and increasing to 0.4 mJ/mm2 (4.0 bar). Standard radiographies of the affected heels were obtained before and after the therapy. Clinical results demonstrated excellent (no pain) in 66.7% of the cases, good (50% of pain reduced) in 15.7% of the cases, and unsatisfactory (no reduction in pain) in 17.6%. After five ESWT treatments, no patients who received shock wave applications had significant spur reductions, but 19 patients (17.6%) had a decrease in the angle of the spur, 23 patients (21.3%) had a decrease in the dimensions of the spur, and one patient had a broken spur. Therefore, results showed no correlation between clinical outcome and radiologic changes. The present study supports the finding that even with no radiologic change after ESWT therapy, the therapy produces significant effects in reducing patients’ complaints about heel spurs.”

Material and methods: Twenty-one patients were included in the study (mean age 51.29 +/- 2.02 yrs, mean duration of symptoms 10.14 +/- 1.11 mos). Radial shock wave therapy was administered in five sessions. Total number of shocks per session was 2500 at a pressure of 2.5 bars. Visual analog scale (VAS) and a modification of the clinical rating system of the American Orthopedic Foot and Ankle Society (AOFAS) were used for outcome measurement. The patients were assessed before treatment and followed up 3, 6, and 12 months after end of treatment.

Results: Statistically significant improvement in pain and functional capacity was found after completion of treatment in comparison with baseline; the improvement was preserved throughout a one-year follow-up.

Materials and Methods: In the experimental group (n = 30), the intensity of the shock wave was increased every two subsequent treatment sessions. In the control group (n = 32), the treatment parameters were not changed. In both groups, six treatments were performed, with two treatment sessions a week. In order to assess the biomechanical parameters of the plantar fascia, myotonometric measurements were performed. The pain intensity was assessed using the Visual Analog Scale (VAS).

Conclusions: The use of rESWT performed with an increasing intensity of impact during subsequent treatment procedures demonstrated greater effectiveness in improving the biomechanical parameters of the plantar fascia and was also more effective in reducing the pain ailments. Our results are encouraging. The dose escalation in the treatment cycle is worth considering.

“Results: Fifty-five patients were followed up, 5 patients were lost to follow-up, two in the PRP group and three in the PRP+ESW group, the follow-up time varied from 6 to 18 months, with an average of 12.7$5.2 months. At 8, 12, 16, 20, and 24 weeks following intervention, the callus score in the monotherapy group was significantly lower than in the combined treatment group (p

“Results: The main types of morbidity included rotator cuff tendonitis, lateral epicondylitis, finger tendonitis, and long bicipital tendonitis. The results of the meta-analysis showed that ESWT was effective in relieving pain in all four types of tendonitis. In addition, ESWT was more effective in relieving pain in patients with upper limb tendonitis than placebo at the 3- and 6-month follow-ups, especially with radial ESWT (RESWT). Data analysis of the forest plot showed that the experimental group with ESWT as an intervention had a significant improvement in function in patients with rotator cuff tendonitis at the 3-month follow-up. However, subgroup analysis showed that low-energy ESWT was effective in improving function in patients with calcified and non-calcified rotator cuff tendonitis, whereas it was not effective in relieving pain.

Conclusion: ESWT can effectively improve the functional activity in patients with rotator cuff tendonitis and may produce positive analgesic effects in patients with upper limb tendonitis. The incidence of adverse effects is low.“

Background: Tendinopathies affecting the hip and pelvis include proximal hamstring tendinopathy (PHT), gluteal tendinopathy (greater trochanteric pain syndrome [GTPS]), and calcific tendinopathy (CT). Extracorporeal shockwave therapy (ESWT) is a noninvasive treatment described for the management of lower-extremity tendinopathies. Purpose: We sought to synthesize the evidence on ESWT used in the treatment of hip/pelvis tendinopathies, including protocols, outcomes, and safety. Methods: A comprehensive search of PubMed/Medline, EMBASE, and Cochrane Library databases was performed on November 1, 2024, for studies reporting ESWT data for hip/pelvis tendinopathies. Study design, population, and ESWT-related data (protocols, outcomes, and safety) were extracted. Results: Eighteen studies were included; 9 reported on GTPS, 7 on CT, and 5 on PHT. Most ESWT protocols (72% [n = 13]) implemented 3 to 4 weekly sessions and delivered 2000 to 3000 pulses/session (83% [n = 15]). Eleven studies used radial ESWT and 7 used focused ESWT. ESWT significantly improved pain and functional outcomes for GTPS, CT, and PHT in 17 level-I to level-V studies; only 1 level-V study showed no improvement. Six studies showed superior outcomes post-ESWT vs conservative treatment (PHT/GTPS), sham ESWT (GTPS), ultrasound therapy (GTPS/CT), or corticosteroid injection (GTPS). One study showed comparable outcomes between ESWT and eccentric exercise (GTPS). Two studies reported no outcome differences between radial ESWT and “minimal-dose” ESWT (GTPS) or combined ESWT (PHT). All studies assessing pain showed improvement from 0.5 to 27 months post-ESWT. Six of 18 studies reported adverse events, including increased pain and skin irritation (overall rate: 12% [n = 65/557]). Conclusions: The results of this systematic review suggest that ESWT may be safe and effective for hip/pelvis tendinopathies. Future research using validated outcome measures and ESWT parameters will aid in treatment optimization.

“The use of ESWT in patients with a known history of osteoporosis may be indicated, as suggested by the increased BMD levels and interpretation of decreased degenerative changes in the 12-month intervention following treatment. ESWT for the treatment of pain secondary to heterotopic ossification due to spinal cord injury was found to be effective through continued use of ESWT, as indicated by decreased VAS scores reported by patients and decreased NHO measurements. Similarly, the treatment of pain secondary to cervical spondylosis also suggested the effectiveness of ESWT, as indicated by decreased patient-reported pain levels. Furthermore, the use of ESWT as an adjunct treatment in patients with cervical spondylosis and calcification of the nuchal ligament was associated with improved ROM and lower NDI scores, suggesting the benefits of ESWT are not limited to pain reduction.”

Methods: This was a 2-parallel-group, active-control, assessor-blinded, randomized trial. We randomized 103 diabetic patients with shoulder AC to receive either 4 sessions of rESWT, 1 week apart (rESWT group, n = 52), or a single ultrasound-guided low-dose intra-articular steroid injection of 20 mg of triamcinolone acetonide (steroid group, n = 51). The primary outcome measure was functional improvement evaluated by the Quick Disabilities of the Arm, Shoulder and Hand (qDASH) score. Secondary outcome measures were pain evaluated by the visual analog scale score and shoulder range of motion (ROM). An assessor who was blinded to treatment assignment assessed both groups at baseline and at 4, 8, and 12 weeks thereafter.

Results: By 12 weeks, both groups demonstrated a significant reduction in the qDASH score and pain severity, as well as improvement in ROM. However, significantly improved function (qDASH score, 40.4 ± 12.9 vs. 50.5 ± 13.3; P < .001) and shoulder pain reduction (visual analog scale score, 1.6 ± 1.2 vs. 2.8 ± 1.7; P < .001) were found in the rESWT group vs. the steroid group. Similar improvement in shoulder ROM was observed in both groups.

“Therapies were administered once a week for 5 sessions by the same practitioner. The energy dose was controlled by the operator to a “maximal comfortably tolerated” level, which was different for each patient and varied between sessions.
During each session, the number of impacts was 2000, the energy density was 0.06 to 0.1 mJ/mm?, the pressure was 1.5 to 2.5 Pa, and the frequency was 6 to 8 Hz. Patients were given standardized postprocedural advice after ESWT and were advised to avoid nonsteroidal anti-inflammatory drugs (NSAIDs) the day of, and a few days after, each ESWT session.”
