Effects Of Extracorporeal Shock Wave Therapy Research Articles

Comparative effectiveness of extracorporeal shock wave therapy, local corticosteroid injection, and conventional physiotherapy in treatment of chronic lateral epicondylitis

BackgroundLateral epicondylitis (LE) is a popular overuse syndrome involving the forearm’s extensor tendons. Corticosteroid (CS) injection is the popular injection used for management of LE. Extracorporeal shockwave therapy (ESWT) is a noninvasive alternative inducing the neovascularization, tendon repairing, and decreasing pain. Our study aimed to compare the effectiveness of ESWT versus local CS injection versus conventional physiotherapy (PT) in management of chronic LE.ResultsOur results revealed that the three groups displayed a significant decrease of VAS score, decrease of PRTEE score, and increase of grip strength compared to baseline (P < 0.05) at 4 weeks and 12 weeks of follow-up. However, there was a significant decrease of VAS score in ESWT and CS groups more than PT group at 4 weeks follow-up (P < 0.05) while ESWT group displayed a considerable improvement in functional disability score (decrease in PRTEE score) more than CS and PT groups at 4 and 12 weeks of follow-up (P < 0.05), with no considerable change in HGS between the three groups.ConclusionESWT, local CS injection, and conventional PT were efficient in management of chronic LE at 12 weeks of follow-up but ESWT had a higher effect decreasing pain and improving functional disability in daily life activity at short and long term follow-up.

Effects of Extracorporeal Shockwave Therapy on Improvements in Lymphedema, Quality of Life, and Fibrous Tissue in Breast Cancer-Related Lymphedema.

ObjectiveTo evaluate the effects of extracorporeal shockwave therapy (ESWT) on improving lymphedema, quality of life, and fibrous tissue in patients with stage 2 lymphedema.MethodsBreast cancer-related lymphedema patients referred to the rehabilitation center were recruited. We enrolled stage 2 lymphedema patients who had firmness of the skin at their forearm, a circumference difference of more than 2 cm between each arm, or a volume difference between upper extremities greater than 200 mL, confirmed by lymphoscintigraphy. The patients were randomly divided into the ESWT group and the control group. ESWT was performed for 3 weeks (two sessions per week); both groups received complex decongestive physical therapy. All patients were evaluated at baseline and at 3 weeks after treatment. The measurements performed included visual analog scale score, volume, circumference, QuickDASH (Quick Disabilities of the Arm, Shoulder and Hand) score, bioelectrical impedance, and skin thickness.ResultsThe patients in both groups (n=15 in each group) completed the 3-week therapy experiment. No significant differences were observed in demographic characteristics between groups. After the 3-week treatment period, improvement was noted in the circumference difference below the elbow, volume, ratio of extracellular water to total body water, and skin thickness in the ESWT group. A significant difference was found in all the above-mentioned areas except in circumference below the elbow in the ESWT group.ConclusionESWT reduced edema and skin fibrosis without significant complications. Therefore, ESWT can be used together with complex decongestive physical therapy for treating lymphedema.

Extracorporeal Shockwave Therapy for Painful Chronic Traumatic Heterotopic Ossification after Right Acetabulum Fracture Fixation: A Case Report and Literature Review

BACKGROUND: Heterotopic ossification (HO) usually occurs in trauma, such as fractures. To the best of our knowledge, there is a lack of studies about the effects of shockwave on the size of HO in the literature.&#x0D; AIM: The aim of this study was to describe the effects of extracorporeal shockwave therapy (ESWT) on the size of HO as well as the lower extremity functions in patients with fracture right acetabulum.&#x0D; CASE REPORT: A 36-year-old gentleman had a traffic accident on August 30, 2015, resulted in a fracture of the right acetabulum treated by open reduction and internal fixation on September 2, 2015. The patient has complained of severe right hip pain with limitation of daily activities, especially walking, standing, and sitting, visual analog scale about 7-8/10 with painful and restricted ROM of the right hip. Plain X-ray of the right hip revealed HO at greater trochanter with a long axis length 37.3 mm. ESWT was applied for HO. ESWT was administered 6 times each weekly for 6 weeks. At 6-month follow-up, the size of HO had become slightly smaller with the improvement of pain, and lower extremities functions.&#x0D; DISCUSSION: Soft tissues around HO have been regenerated from ischemia for several reasons such as ESWT stimulating angiogenesis and neurogenesis and the size of HO had become slightly smaller by radial shockwave therapy.&#x0D; CONCLUSION: ESWT is a novel non-invasive and safe treatment for HO. The effects of ESWT on the size of HO had become slightly smaller with the improvement of lower extremities functions.

Effects of extracorporeal shock wave therapy in patients with knee osteoarthritis: A cohort study protocol.

Background:Osteoarthritis is the most common form of arthritis, and is a major cause of disability and chronic pain in adults. However, there is very limited evidence in the scientific literature to support the effectiveness of extracorporeal shockwave therapy (ESWT) in human knee osteoarthritis. This retrospective study aimed to compare the efficacy of ESWT treatment with sham-ESWT on pain, walking speed, physical function, and adverse effects in knee osteoarthritis.Methods:This study will be performed and reported in accordance with the Strengthening the Reporting of Observational studies in Epidemiology checklist. We reviewed patients diagnosed with knee osteoarthritis at our academic center from 2016 to 2017. This retrospective cohort study was approved by the institutional review board in Ruijin Hospital. The primary outcome measure was pain on movement measured by a 100-cm visual analog scale. The secondary outcome measures included the Western Ontario and McMaster University Osteoarthritis Index, range of motion, and adverse effects. Statistical analysis was performed using Statistical Package for Social Sciences version 20.0 (IBM Corporation, Armonk, NY). A P-value of <.05 was defined as statistical significance.Results:The hypothesis was that ESWT would be an effective treatment for improving pain and physical function in knee osteoarthritis to control symptoms.Trial registration:This study protocol was registered in Research Registry (researchregistry5801).

Extracorporeal shockwave therapy improves pain and function in subjects with knee osteoarthritis: A systematic review and meta-analysis of randomized clinical trials.

To examine the safety and effectiveness of extracorporeal shockwave therapy (ESWT) for reducing pain and improving functionality in people with knee osteoarthritis (KOA). The Cochrane Library, PubMed, CINAHL, Physiotherapy Evidence Database (PEDro) and Google Scholar were systematically searched for randomized trials published up to September 30th of 2019. The main outcome measures to evaluate the treatment effect were pain, as reported on a visual analogue scale (VAS), and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Secondary outcome measures were the range of motion (ROM) and walking tests. A quantitative analysis was conducted using the inverse variance method and the random effects model. Fourteen studies were included (n=782 participants and 877 knees). Moderate quality of evidence showed that ESWT causes a decrease on the pain VAS [mean difference (MD)=1.7cm; confidence interval (CI) 95%: 1.1-2.3] and WOMAC (MD=13.9 points; CI 95%: 6.9-20.8). The effect of ESWT using medium energetic density was greater than with low or high density in the WOMAC (Chi2=9.8, p=0.002) and bordered statistical significance on the VAS (Chi2=3.8, p=0.05). Very low quality of evidence showed that ESWT causes moderate improvement in the knee ROM (MD=17.5°; CI 95%: 9.4-25.5) and walking test [standardized mean difference (SMD)=0.58; CI 95%: 0.35-0.81]. ESWT is an effective treatment for improving pain and functionality in patients with KOA in the short term with few minor side effects. Further clinical trials should include longer follow-up periods and be designed to lower the risk of bias.

Extracorporeal shock wave therapy accelerates endochondral ossification and fracture healing in a rat femur delayed-union model

Extracorporeal shock wave therapy (ESWT) has been demonstrated to accelerate bone healing; however, the mechanism underlying ESWT-induced bone regeneration has not been fully elucidated. This study aimed to examine the effects of ESWT and the process of fracture healing. A rat model of femur delayed-union was established by cauterizing the periosteum. ESWT treatment at the fracture site was performed 2 weeks after the operation and the site was radiographically and histologically evaluated at weeks 4, 6, and 8. The bone union rate and radiographic score of the ESWT group were significantly higher than those of the control group at 8 weeks. Histological evaluation revealed enhanced endochondral ossification at the fracture site. The effects of ESWT on ATDC5 cells were examined in vitro. ESWT promoted chondrogenic differentiation without inhibiting the proliferation of ATDC5 cells. ESWT may induce significant bone healing by promoting endochondral ossification at the fracture site.

Extracorporeal Shock Wave Therapy in the Treatment of Knee Osteoarthritis: A Review of Mechanism of Action and Clinical Efficacy

Knee osteoarthritis (KOA) is the most common form of arthritis and one of the leading causes of disability. OA is characterized by cartilage damage, subchondral bone changes, and synovial tissue inflammation, with clinical symptoms of pain, decreased range of motion (ROM) and functional impairment. Recently, extracorporeal shockwave therapy (ESWT) has been introduced in the treatment of OA and there is increasing evidence of the therapeutic effects of ESWT on patients with KOA. For decades, there have been multiple attempts to understand the mechanisms of these therapeutic effects. So far, it is appreciated that cellular mechanotransduction through the cytoskeleton into the nuclei can regulate gene expression and cause biological changes. The purpose of this article is to provide current evidence on the physical and biological principles, mechanism of action and clinical efficacy of ESWT on KOA.

Analgesic effect of extracorporeal shock-wave therapy for frozen shoulder: A randomized controlled trial protocol.

Background:Till date only a few studies have reported the efficacy and clinical improvements obtained by extracorporeal shock-wave therapy (ESWT) on frozen shoulder. Limited by small number of studies and insufficient outcomes, it is important and necessary to conduct a new randomized controlled trial. The purpose of the present study is to determine whether ESWT could be more effective than oral steroid in treatment of frozen shoulder.Methods:This randomized, single-blind, superiority clinical trial was approved by the institutional review board in The Third People's Hospital of Linyi. The inclusion criteria were patients aged >18 years with shoulder pain and restriction in range of motion. A symptom duration >3 months was required, with no radiographic findings on anteroposterior shoulder plain radiographs except for osteoporosis. Group 1 patients were given 30 mg of oral prednisolone daily for 2 weeks as a single morning dose and then 15 mg daily for another 2 weeks. Group 2 patients received 3 sessions of ESWT on the first, 14th, and 28th days. The primary outcome measure was shoulder pain score. The secondary outcomes included Disabilities of the Arm, Shoulder, and Hand score, range of motion, satisfaction rate, and complications.Results:It was hypothesized that there would be a significant difference between ESWT and control groups in improving shoulder pain and functions in frozen shoulder.Trial registration:This study protocol was registered in Research Registry (researchregistry5736).

Extracorporeal shockwave therapy enhances peripheral nerve remyelination and gait function in a crush model.

Conservative treatment, such as electrical stimulation and steroid injection, have been employed in an attempt to improve symptoms after peripheral nerve injury, without significant success. Although non-invasive and safe extracorporeal shockwave therapy (ESWT) can be a practical alternative, the therapeutic effects of ESWT on peripheral nerve remyelination has not been established. To investigate the effects of ESWT on peripheral nerve remyelination and gait function for 5 weeks in a sciatic nerve crush model. In total, we divided 97 rats into 5 groups: group 1 - a healthy negative control group; group 2 - 3 weeks after sciatic nerve crush and 3 sessions of ESWT; group 3 - 5 weeks after crush injury with 3 sessions of ESWT; group 4 - 3 weeks after crush injury with no ESWT; and group 5 - 5 weeks after crush injury with no ESWT. The focused ESWT was applied to the unilateral sciatic nerve injury site. One session consisted of 1,500 stimuli, and the session were performed at intervals of 1 week. The degree of myelination and expression of myelin basic protein at the distal part of the injured sciatic nerve tended to increase in the ESWT groups compared with the no-ESWT groups 3 and 5 weeks after crush injury. Regarding the functional gait recovery, the print width and area of the injured leg in the ESWT groups was significantly larger than that in the no-ESWT groups 3 and 5 weeks after crush injury. The ESWT may enhance peripheral nerve remyelination and gait function in a nerve crush model. Long-term follow-up after ESWT and investigation of molecular mechanisms will be needed to confirm these therapeutic effects.

Review of the Current Status of Low Intensity Extracorporeal Shockwave Therapy (Li-ESWT) in Erectile Dysfunction (ED), Peyronie's Disease (PD), and Sexual Rehabilitation After Radical Prostatectomy With Special Focus on Technical Aspects of the Different Marketed ESWT Devices Including Personal Experiences in 350 Patients.

Although the literature of the positive effects of penile low intensity extracorporeal shockwave therapy is meanwhile substantial, there are substantial differences regarding both the sources of energies and extracorporeal shockwave therapy (ESWT) devices. To provide an overview on the energy range and energy differences of the 6 currently marketed ESWT devices along with personal ESWT experiences in 350 patients. This review includes all published preclinical and clinical penile ESWT studies with evaluation of the technical differences of the 6 ESWT devices and the personal experiences with these 6 devices in ED and PD. The main outcomes measures were success rates in ED (International Index of Erectile Function-erectile function change, conversion of phosphodiesterase type 5 inhibitors non-responders) and PD (change in deviation and plaque size), differences of used sources of energy, and energy flux densities (EFDs). 3 different sources of energies are used, that is electromagnetic, electrohydraulic, and piezoelectric .The devices markedly distinguish in the available spectrum of the EFD ranging between 0.09 and 0.55 mJ/mm². In terms of the biological effects, the relevant energy parameters are-6 dB and the 5 MPa focus, which differ substantially between the ESWT devices. In addition, a great variability in the treatment protocols and applied energy is obvious. The preliminary own experiences with low intensity extracorporeal shockwave therapy in 160 ED non-responders and 190 patients with PD with success rates of 45% and 47%, respectively, are reported. Positive results were published with all 6 ESWT devices in question in patients with organic ED but with huge differences regarding the EFD and the total energies applied. There is growing evidence that concentrated treatment protocols and increasing energies may yield better results. In this context, it may be argued that at least some of the published studies were markedly underpowered .Owing to the paucity of published studies, the literature of the effects of ESWT in PD and for penile rehabilitation after pelvic surgery is currently not conclusive.

Innovative technologies in the treatment of humeroscapular pain syndrome at a health resort rehabilitation stage

In modern sanatorium-resort organizations there is an urgent need of effective innovative physiotherapeutic methods usage along with basic resort treatment, that is especially important for patients’ resort treatment duration reduction. Extracorporeal shock wave therapy (ESWT) is evidence-based physiotherapeutic method. The aim of the study is to evaluate the high clinical efficacy of ESWT method in comparison with traditional methods of treatment at the sanatorium-resort complex «Vulan». Materials and methods: ESWT method effectiveness study was carried out in 111 people with shoulder joints and periarticular tissues pathology of various etiology aged 30-79 years (average age 45.5 years), disease duration from 1 year to 10-12 years (average 4.5 years). Results: According to the Swanson Score, in patients of the main group (n=57) «pain score» improved from 3.5 (before) to 8.3 (after), that is 2.3 times. “Activity in everyday life” raised from 4.7 to 8.6 (1.7 times), the volume of active movements increased from 3.2 to 7.9 (2.5 times). According to the Likert scale, patients reported a subjective improvement in their own well-being by 4.6 point. According to VAS scale a decrease in pain syndrome intensity was recorded (2.2 times in average). In patients of comparison group, who received basic resort treatment, positive changes were less significant. Conclusion: Objective and subjective data obtained in this study indicates a high clinical effect of ESWT in a complex health-resort treatment of patients with humeroscapular pain syndrome.

Does the Type of Extracorporeal Shock Therapy Influence Treatment Effectiveness in Lateral Epicondylitis? A Systematic Review and Meta-analysis.

Extracorporeal shock wave therapy (ESWT) has been used in various musculoskeletal disorders, including lateral epicondylitis. However, in 2005, a meta-analysis of randomized controlled trials showed that ESWT provides minimal or no benefit in terms of pain and function in patients with lateral epicondylitis. Since the review, several randomized controlled trials including different types of ESWT such as radial type for lateral epicondylitis have been published. Investigations of the effect modifiers such as symptom and follow-up duration on the effects of ESWT on lateral epicondylitis have not been performed. (1) Does ESWT reduce pain and improve grip strength in patients with lateral epicondylitis? (2) Which type of ESWT, radial or focused, is more effective? (3) Is the duration of symptoms associated with the efficacy of ESWT for lateral epicondylitis? (4) Do improvements in pain scores remain in patients with longer follow-up? The PubMed, Embase, and Cochrane Central Register of Controlled Trials databases were searched up to July 2019 for articles published in English or Korean. Studies were included if patient allocation was randomized, the sample was composed of patients with lateral epicondylitis, interventions were ESWT (focused or radial), comparison group only received sham stimulation or no additional treatment, and the study outcome was pain intensity or grip strength. The quality of the evidence was assessed using the Cochrane risk of bias tool. Twelve studies including 1104 participants fulfilled the inclusion criteria and were included in the meta-analysis. The mean difference for pain reduction and improvement in grip strength was calculated. The meta-analysis showed no clinically important difference in the VAS score (2.48 ± 7.55 versus 3.17 ± 9.78, mean difference -0.68 [95% confidence interval -1.17 to -0.19]; p = 0.006) and grip strength (38.02 ± 70.56 versus 34.85 ± 108.26, mean difference 3.33 [95% CI 0.93 to 5.73]; p = 0.007) after ESWT relative to the comparison group's score. Even though radial ESWT showed more improvement than focused, the mean difference for VAS did not exceed the minimal clinically important differences threshold. There were no clinically important effects on the VAS scores of patients with lateral epicondylitis (2.78 ± 5.57 versus 3.92 ± 6.29, mean difference -1.13 [95% CI -1.84 to -0.42]; p = 0.002) and focused ESWT did not improve pain in patients with lateral epicondylitis. In the subgroup analysis, ESWT was effective in patients with a symptom duration of more than 6 months (2.28 ± 8.48 versus 3.31 ± 11.81, mean difference -0.95 [95% CI -1.75 to -0.15]; p = 0.02) but not for those with shorter symptom duration. The effects did not last beyond 24 weeks (2.52 ± 9.19 versus 3.34 ± 5.93, mean difference -0.82 [95% CI -2.57 to 0.93]; p = 0.36). ESWT did not show clinically important improvement in pain reduction and grip strength. Radial ESWT, symptom duration of longer than 6 months, and short follow-up duration (less than 24 weeks) were related to better effects. Further studies are needed to determine the appropriate protocol and elucidate the effects according to the intervention type and specific disease condition. Level I, therapeutic study.

the aim of this study was to evaluate the effect of extracorporeal shockwave therapy on CPPS due to non bacterial prostatitis. s: There were two groups in the study. 78 patients in the first group received 6 sessions of Low intensity-shokwave therapy (Li-ESWT) in three weeks. 40 patients from group "2" were receiving diclofenac sodium in the form of suppositories. Patients in the first group showed significant improvement of pain and quality of life in comparison to the control group, which experienced less significant improvements. Low intensity-shokwave therapy (Li-ESWT) is effective in chronic pelvic pain syndrome treatment.

Efficacy of Extracorporeal Shock Wave Therapy for Lateral Epicondylitis: A Systematic Review and Meta-Analysis.

Background Lateral epicondylitis (LE) is a common elbow problem. Extracorporeal shock wave therapy (ESWT) was widely used in the treatment of LE and has been shown to relieve the pain and functional impairment (loss of grip strength) caused by tennis elbow. However, the evidence with regard to whether ESWT has better clinical efficacy over other method is not clear. The aim of the study was to compare the effectiveness of ESWT with other techniques in the treatment of LE. Methods Literature searches of PubMed, OVID, Embase, Cochrane Library, and Web of Science were searched up to 30th June, 2019. Only RCTs comparing ESWT with other methods for LE were included. Data collection and extraction, quality assessment, and data analyses were performed according to the Cochrane standards. Results A total of 13 articles with 1035 patients were included. Of which, 501 underwent ESWT and 534 underwent other methods. The result of meta-analysis showed that pooled VAS (P = 0.0004) and grip strength (P < 0.00001) were better in the ESWT group. Conclusion Based on the existing clinical evidence, extracorporeal shock wave therapy can effectively relieve the pain and functional impairment (loss of grip strength) caused by tennis elbow, with better overall safety than several other methods. However, owing to the limited quality and quantity of the included studies, more high-quality RCTs are needed to support the trend towards better functional outcomes with ESWT.

The effect of focused extracorporeal shock wave therapy on myofascial pain syndrome of trapezius: A systematic review and meta-analysis.

Background:Myofascial pain syndrome (MPS) is commonly seen in clinical settings and negatively influences a patient's daily life. Recently, the application of extracorporeal shock wave therapy (ESWT) has been utilized as one of the treatment methods for MPS. The aim of this systematic review and meta-analysis was to summarize the current evidence for the short-term effect of ESWT on MPS of trapezius.Methods:PubMed, EMBASE, Web of Science, and Cochrane Central Register of Controlled Trials were searched from the database inception to March 2019. Two reviewers independently screened articles, evaluated methodological quality, and extracted data. The primary outcome was post-interventional pain intensity.Results:Randomized controlled trials (RCTs) were conducted to determine whether ESWT was used as the main treatment on MPS. The 5 studies reviewed in this meta-analysis were evaluated for changes in pain intensity. Compared with other treatments, focused ESWT in MPS was more effective in reducing the scores of visual analog scale (VAS) (standardized mean difference [SMD] = −0.48, 95% CI −0.74 to −0.22).Conclusions:There is very low level evidence that focused ESWT is effective for short-term relief of neck pain in MPS. The limited sample size and poor quality of these studies highlight and support the need for large scale, good quality placebo controlled trials in this area.

Extracorporeal shock wave therapy for treatment of vulvodynia: a prospective, randomized, double-blind, placebo-controlled study.

Currently, there are no effective therapy strategies for idiopathic, non-organic vulvodynia in women. ESWT (extracorporeal shock wave therapy) is a nonsurgical/noninvasive technique widely used to treat musculoskeletal diseases, muscle spasticity and hypertonia, renal and biliary calculi and urological disorders. We examined the effects of ESWT on vulvodynia in women. A prospective, randomized, double-blind, placebo-controlled study was conducted between 2015 and 2018 following a feasibility study. Obstetrics and Gynecology Hospital departments. The study included 62 women with vulvodynia for at least 3 months. The women were randomly assigned to either a treatment group (N.=31) or a placebo group (N.=31). The patients in the treatment group received perineally applied ESWT weekly (3000 pulses each for four consecutive weeks). The energy flux density was 0.25 mJ/mm2, frequency 4 Hz, focus zone 0-30 mm, therapeutic efficacy 0-90 mm, stand-off II. The device used was a standard electromagnetic shock wave unit with a focused shock wave handpiece. The position of the shock wave transducer was changed six times after every 500 pulses. Patients in the placebo group underwent the same treatment procedure, but the handpiece was provided with a placebo stand-off that disabled energy transmission. Subjective pain was self-evaluated by each patient using two tools before and after treatment: a 10 cm linear visual analogue scale (VAS, 0-10) and a cotton-swab test (CST, Goetsch scale 0-4). Follow-ups were done 1, 4, and 12 weeks post-ESWT. In all, 61 women completed the study. We tested for differences in the VAS and CST within and between the treatment and placebo groups. The testing was between before treatment and particular follow-up. We found significant changes in the treatment group. Reductions in VAS (P<0.01) and CST (P<0.01) were observed at all three follow-ups. At all assessments, pain reduction was always >30%. In the placebo group there were no statistically significant changes between before and after treatment. There were no differences between the treatment and placebo groups before treatment but statistically significant differences at all three follow-ups (VAS P<0.01); CST P<0.01). ESWT seems to reduce pain perception in our treatment group. Thus, we are encouraged to explore this technique further. The method is easily replicable, inexpensive, and without known side effects.

Effectiveness of Extracorporeal Shockwave Therapy in the Treatment of Chronic Insertional Achilles Tendinopathy.

Extracorporeal shockwave therapy (ESWT) has been proposed as a conservative treatment for insertional Achilles tendinopathy from limited evidence without placebo controls. Our objective was to assess the effectiveness of ESWT compared with sham controls in chronic insertional Achilles tendinopathy. A double-blind, randomized sham-controlled trial was conducted between 2016 and 2018. The inclusion criteria were patients aged 18 to 70 years diagnosed with chronic insertional Achilles tendinopathy who failed standard conservative treatment. After computerized randomization, patients were allocated into either low-energy ESWT or sham control. Pain, function, and other complaints were assessed using visual analog scale (VAS) and VAS foot and ankle (VAS-FA) at preintervention and weeks 2, 3, 4, 6, 12, and 24. Intention-to-treat analysis and repeated measurement were performed using STATA 15.0. Sixteen patients in ESWT and 15 patients in sham control groups had nonsignificant different baseline characteristics with preintervention VAS (6.0 ± 2.6 vs 5.2 ± 2.2) and VAS-FA (64.8 ± 16.6 vs 65.3 ± 12.7). There was no significant difference in VAS, VAS-FA, and its domains in the long term between the 2 groups. In addition, the ESWT group had significant improvement in VAS (2.9 ± 2.2) at weeks 4 to 12, and sham controls group had significantly improved VAS (2.3 ± 2.6) at weeks 12 to 24. Complications were found only after ESWT treatment. There was no difference at 24 weeks with the use of low-energy ESWT for chronic insertional Achilles tendinopathy, especially in elderly patients. However, it may provide a short period of therapeutic effects as early as weeks 4 to 12. Level I, randomized controlled study.

Effect of extracorporeal shockwave therapy on myofascial pain syndrome of upper trapezius: A systematic review

Neck pain is highly prevalent condition, with myofascial pain syndrome (MPS) affecting 95% of people. Extracorporeal shockwave therapy (ESWT) being novel idea for this condition provides non-intrusive, less time consuming and tolerable sound electro physical therapy. The aim of the systematic review was to find and summarize the effectiveness of ESWT associated with different parameters on MPS of upper trapezius. Data were extracted from e-search engine, PubMed, research gate, semantic scholar, magonlinelibrary, Cochrane Library, Google scholar, and MedlinePlus. Systematic review design was done according to Problem, Intervention, Comparison, outcome, and time format, and systematic review was conducted according to PRISMA statement. List of keywords were searched and definite inclusion criteria were developed prior. Total 15 studies met the inclusion criteria. Descriptive analysis was done to find effectiveness of ESWT. Significant effectiveness of ESWT is found for the patients with MPS of upper trapezius. High-density focused ESWT is more significant results than others with pulses delivered minimum of 1000 per session. However, more high quality studies need to be done to conclude effectiveness of radial and combined ESWT.

The effects of shock wave therapy applied on hypertrophic burn scars: a randomised controlled trial.

Introduction:A wide variety of non-invasive treatments has been proposed for the management of hypertrophic burn scars. Unfortunately, the reported efficacy has not been consistent, and especially in the first three months after wound closure, fragility of the scarred skin limits the treatment options. Extracorporeal shock wave therapy (ESWT) is a new non-invasive type of mechanotherapy to treat wounds and scars. The aim of the present study was to examine the objective and subjective scar-related effects of ESWT on burn scars in the early remodelling phase.Material and methods:Evaluations included the Patient and Observer Scar Assessment Scale (POSAS) for scar quality, tri-stimulus colorimetry for redness, tewametry for trans-epidermal water loss (TEWL) and cutometry for elasticity. Patients were randomly assigned to one of two groups, the low-energy intervention group or the placebo control group, and were tested at baseline, after one, three and six months. All patients were treated with pressure garments, silicone and moisturisers. Both groups received the ESWT treatment (real or placebo) once a week for 10 weeks.Results:Results for 20 patients in each group after six months are presented. The objective assessments showed a statistically significant effect of ESWT compared with placebo on elasticity (P = 0.011, η2P=0.107) but revealed no significant effects on redness and TEWL. Results of the clinical assessments showed no significant interactions between intervention and time for the POSAS Patient and Observer scores.Conclusion:ESWT can give added value to the non-invasive treatment of hypertrophic scars, more specifically to improve elasticity when the treatment was already started in the first three months after wound closure.Lay SummaryPathological scarring is a common problem after a burn injury. A wide variety of non-invasive treatments has been proposed for the management of these scars. Unfortunately, the reported efficacy of these interventions has not been consistent, and especially in the first three months after wound closure, fragility of the scarred skin limits the treatment options. Extracorporeal shock wave therapy (ESWT) is a relatively new non-invasive therapy to treat both wounds and scars. The aim of the present study was to examine the scar-related effects of ESWT on burn scars in the early phase of healing.The scars were subjectively assessed for scar quality by the patient and an observer using the Patient and Observer Scar Assessment Scale (POSAS). Objective assessments included measurements to assess redness, water loss and elasticity. Forty patients were randomly assigned to one of two groups, the low-energy intervention group or the placebo control group (the device simulated the sound of an ESWT treatment but no real shocks were applied), and were tested at four timepoints up to six months. All patients were treated with pressure garments, silicone and moisturisers. Both groups received the ESWT treatment (real or placebo) once a week for 10 weeks.The objective assessments showed a significant improvement of elasticity in the intervention group when compared with placebo but revealed no significant effects on redness and water loss. Results of the clinical assessments showed no differences between the groups for the POSAS Patient and Observer scores.ESWT can give added value to the non-invasive treatment of pathological scars more specifically to improve elasticity in the early phase of healing.
