Application of Local Anesthesia Inhibits Effects of Low-Energy Extracorporeal Shock Wave Treatment (ESWT) on Nociceptors

Sonographic and clinical effects of manual physical therapy for plantar fasciitis: randomized prospective controlled trial

OBJECTIVE

This study aimed to evaluate the efficacy of manual physiotherapy on clinical outcomes, morphology of plantar fascia (PF), thicknesses of calcaneal fat pad (CFP) and Kager's fat pad (KFP) with ultrasound imaging in plantar fasciitis (PFS) patients. Also, to evaluate the PF thickness, pain and foot functional outcomes among PFS phases.

METHODS

A randomized controlled trial was conducted on 122 subjects divided into three groups: group A (40 patients with PFS) underwent manual physiotherapy, group B (42 patients with PFS) without any intervention and group C (40 healthy subjects) were matched by age, gender and BMI with each patient in group A and B. The following outcomes were evaluated at baseline and one-month of follow-ups: morphology of PF and thicknesses of CFP and KFP, pain, foot functional limitation.

RESULTS

PF thickness was significantly thickened in group A and B compared to group C (P < 0.001). A significant decrease in incidence of PF echogenicity and CFP thickness were found in group A and B compared to group C. Moreover, significant improvement was observed in PF thickness (P < 0.001), PF echogenicity (P < 0.001) and CFP thickness (P = 0.002) in group A at one-month after the treatment. Furthermore, pain intensity and foot functional limitation was significantly improved within group A after receiving the treatment. Significant improvement was noted in PF thickness, pain intensity and foot functional limitation among patients with acute phase.

CONCLUSION

The manual physiotherapy is effective in treatment of PF thickening, hypoechogenicity, pain intensity and activity limitations, particularly in patients associated with acute PFS.

Staying in the Game: Interventions for Managing Achilles Tendinopathy in the In-Season Athlete

ABSTRACT

Achilles tendinopathy is a common overuse injury that is traditionally managed with activity modification and a progressive eccentric strengthening program. This narrative review describes the available evidence for adjunctive procedural interventions in the management of midportion and insertional AT, specifically in the athletic population. Safety and efficacy data from available literature on extracorporeal shockwave therapy, platelet-rich plasma, high-volume injectate with or without tendon scraping, and percutaneous needle tenotomy are used to propose an algorithm for treatment of Achilles tendinopathy for the in-season athlete.

Callus formation and bone remodeling in a tibial nonunion after minimal invasive percutaneous screw fixation followed by extracorporeal shockwave therapy 17-months after initial trauma - A case report

INTRODUCTION

The treatment of tibial nonunion is challenging and treatment may be conservative or surgical. Conservative strategies include functional braces and weight bearing, or focused extracorporeal shockwave therapy (fESWT).

CASE DESCRIPTION

A 45-year-old male patient sustained spiral tibial shaft fractures and was treated surgically within 24 hours after the initial accident with intramedullary nails. The tibial fracture was later classified as nonunion after 11 months. Radiologic evaluation 17 months after the initial trauma demonstrated clinical nonunion, and subsequently the patient was offered a conservative approach with fESWT to facilitate an increase in callus formation. The handpiece was fitted with a stand-off II (long), penetration depth of 15 mm. Three cycles were administered in month 17, 19 and 20 after baseline. Each cycle consisted of three treatments sessions spaced with 6-8 days apart, and consisted of 3000 to 4000 impulses each given at 0.25-0.84 mJ/mm2. The number of impulses and the power at the focus point varied according to the pain response.

OUTCOMES

The patient achieved union 23 months after fracture. A clinical important improvement was observed with both Lower Extremity Functional Scale (LEFS) (18-point difference) and Patient Specific Functional Scale (PSFS) (average: 4.7 points,) The "worst pain last 24 hours" was reduced by 5 points. These values express minimal clinically important difference (MCID) values in these functional patient-reported outcome measures.

CONCLUSION

This treatment strategy may be viable in a broader setting, including private practice physiotherapy thereby treating the patient in close proximity to the patient's everyday life.

Physical Rehabilitation in Zoological Companion Animals

Animal physical rehabilitation is one of the fast-growing fields in veterinary medicine in recent years. It has become increasingly common in small animal practice and will continue to emerge as an essential aspect of veterinary medicine that plays a vital role in the care of animals with physical impairments or disabilities from surgery, injuries, or diseases.1 This is true now more than ever because of the increasing advances in lifesaving treatments, the increased lifespan of companion animals, and the growth of chronic conditions, of which many are associated with movement disorders. The American Association of Rehabilitation Veterinarians (AARV) defines APR as "the diagnosis and management of patients with painful or functionally limiting conditions, particularly those with injury or illness related to the neurologic and musculoskeletal systems." Rehabilitation not only focuses on recovery after surgical procedures but also on improving the function and quality of life in animals suffering from debilitating diseases such as arthritis or neurologic disorders. The overall goal of APR is to decrease pain, reduce edema, promote tissue healing, restore gait and mobility to its prior activity level, regain strength, prevent further injury, and promote optimal quality of life. Typically, a multimodal approach with pharmaceutical and nonpharmaceutical interventions is used by APR therapists to manage patients during their recovery. The purpose of this article aims to provide knowledge and guidance on physical rehabilitation to help veterinarians in the proper return of their patients with ZCA safely after injury and/or surgery.

More than Ninety Percent of the Light Energy Emitted by Near-Infrared Laser Therapy Devices Used to Treat Musculoskeletal Disorders Is Absorbed within the First Ten Millimeters of Biological Tissue

There is increasing interest in the application of near-infrared (NIR) laser light for the treatment of various musculoskeletal disorders. The present study thoroughly examined the physical characteristics of laser beams from two different laser therapy devices that are commercially available for the treatment of musculoskeletal disorders. Then, these laser beams were used to measure the penetration depth in various biological tissues from different animal species. The key result of the present study was the finding that for all investigated tissues, most of the initial light energy was lost in the first one to two millimeters, more than 90% of the light energy was absorbed within the first ten millimeters, and there was hardly any light energy left after 15-20 mm of tissue. Furthermore, the investigated laser therapy devices fundamentally differed in several laser beam parameters that can have an influence on how light is transmitted through tissue. Overall, the present study showed that a laser therapy device that is supposed to reach deep layers of tissue for treatments of musculoskeletal disorders should operate with a wavelength between 800 nm and 905 nm, a top-hat beam profile, and it should emit very short pulses with a large peak power.

Treatment of Jumper’s Knee with Extracorporeal Shockwave Therapy: A Systematic Review and Meta-Analysis

The aim of this systematic review and meta-analysis was to determine the therapeutic efficacy of extracorporeal shockwave therapy (ESWT) for athletes with patellar tendinopathy. We searched PubMed, EBSCOHost and Ovid for randomized controlled trials (RCTs) which evaluated the therapeutic efficacy of ESWT in athletes with jumper’s knee. The methodological quality of RCTs was rated with the Physiotherapy Evidence Database scale. Data in the meta-analysis were expressed as standardized mean difference (SMDs) and 95% confidence intervals (CIs). Heterogeneity was assessed with I2 statistics. Of 192 records identified, a total of seven articles met the inclusion criteria. The ESWT and control groups with any other conservative treatment did not differ significantly with respect to the Visual Analogue Scale (VAS) long-term scores obtained at ≥ 6 months of therapy completion (SMD: -0.33; 95% CI: -4.64 to 3.98; p = 0.87; I2= 98%). Furthermore, no significant differences were found between the ESWT and control groups regarding the pooled Victorian Institute of Sports Assessment for Patella (VISA-P) scores for long-term outcomes (SMD: 8.21; 95% CI: -39.3 to 55.73; p = 0.73; I2= 99%). The ESWT and control groups did not differ significantly on the VAS and VISA-P scores for long-term outcomes. In both cases, heterogeneity was considered to be high. Hence, no clear and generalized conclusions can be drawn regarding ESWT effectiveness in athletes with patellar tendinopathy.

How to report parameters and procedures for shockwave therapy in musculoskeletal disorders: A narrative review

Shockwave therapy (SWT) has been successful in the management of musculoskeletal conditions. The limitations of the use of SWT in clinical practice regard a lack of familiarity with the device and the lack of uniformity in information reported in scientific publications. Standardization in the reporting of these parameters could facilitate the reproduction and interpretation of data in future studies. Most studies fail to offer a detailed description of the parameters. Therefore, the aim of the present paper is to prepare a report on how to standardize the presentation of this information and serve a reference guide to report physical parameters and procedures of SWT when used on patients with musculoskeletal disorders. The terms were selected from the Medical Subject Headings database of controlled vocabulary. An extensive process of systematic searching of databases was performed, after which experts met and discussed on the main findings, and a consensus was achieved. SWT parameters were described, including the physiological meaning and clinical relevance of each parameter. Also, the description of patient and equipment positioning was added. The consensus-based guideline on how to report SWT parameters for the treatment of musculoskeletal conditions was developed to help clinicians and researchers.

Extracorporeal Shockwave Therapy for Foot and Ankle Disorders: A Systematic Review and Meta-Analysis

BACKGROUND

Extracorporeal shockwave therapy (ESWT) was first introduced into clinical practice in 1982 and has been a beneficial inclusion to the noninvasive treatment option of numerous orthopaedic pathologies. However, clinical evidence of the use of ESWT for various foot and ankle disorders has been limited with a consensus on its efficacy yet available. Therefore, the purpose of this study is to systematically review the literature, to provide a critical evaluation and meta-analysis for the use of ESWT in foot and ankle disorders.

METHODS

The PubMed and Embase databases were systematically reviewed and clinical studies that reported ESWT use for various foot and ankle disorders included.

RESULTS

A total of 24 clinical studies that included 12 randomized controlled trials and 12 case series were identified. Analysis of the evidence has indicated that ESWT can help manage plantar fasciitis, calcaneal spur, Achilles tendinopathy and Morton's neuroma. Meta-analysis of the change in pre- to post-VAS overall scores for plantar fasciitis significantly favored ESWT compared to placebo/conservative treatment with a MD -3.10 (95% CI, -4.36 to -1.83; I2 = 68%; P < 0.00001).

CONCLUSIONS

The current evidence has suggested that ESWT can provide symptomatic benefit to plantar fasciitis treatment, with minimal and unremarkable side effects. Overall, ESWT has been demonstrated to be a safe treatment option with a favorable complication profile. Further well-designed studies of ESWT for the treatment of calcaneal spurs, Achilles tendinopathy and Morton's neuroma are warranted to more soundly and safely support its current use. Future studies are suggested to investigate the optimization of ESWT treatment protocols.

Molecular Mechanisms Underlying the Pain-Relieving Effects of Extracorporeal Shock Wave Therapy: A Focus on Fascia Nociceptors

In recent years, extracorporeal shock wave therapy (ESWT) has received increasing attention for its potential beneficial effects on various bone and soft-tissue pathologies, yielding promising outcomes for pain relief and functional recovery. In fact, ESWT has emerged as an alternative, non-invasive, and safe treatment for the management of numerous musculoskeletal disorders, including myofascial pain syndrome (MPS). In particular, MPS is a common chronic painful condition, accounting for the largest proportion of patients affected by musculoskeletal problems. Remarkably, sensory innervation and nociceptors of the fascial system are emerging to play a pivotal role as pain generators in MPS. At the same time, increasing evidence demonstrates that application of ESWT results in selective loss of sensory unmyelinated nerve fibers, thereby inducing long-lasting analgesia. The findings discussed in the present review are supposed to add novel viewpoints that may further enrich our knowledge on the complex interactions occurring between disorders of the deep fascia including changes in innervation, sensitization of fascial nociceptors, the pathophysiology of chronic musculoskeletal pain of MPS, and EWST-induced analgesia. Moreover, gaining mechanistic insights into the molecular mechanisms of pain-alleviating effects of ESWT may broaden the fields of shock waves clinical practice far beyond the musculoskeletal system or its original application for lithotripsy.

Efficacy and safety of treating chronic nonspecific low back pain with radial extracorporeal shock wave therapy (rESWT), rESWT combined with celecoxib and eperisone (C + E) or C + E alone: a prospective, randomized trial

BACKGROUND

To investigate whether respectively radial extracoporeal shock wave therapy (rESWT) or a combination of rESWT, celecoxib and eperisone (rESWT + C + E) are superior in reducing pain in patients with chronic nonspecific low back pain (cnsLBP) compared to C + E alone (a standard treatment of this condition in China).

METHODS

140 patients with cnsLBP were randomly allocated to rESWT (n = 47), rESWT + C + E (n = 45) or C + E alone (n = 48) for four weeks between November 2017 and March 2019. Outcome was evaluated using the Pain Self-Efficacy Questionnaire (PSEQ), Numerical Rating Scale (NRS), Oswestry Low Back Pain Disability Questionnaire and Patient Health Questionnaire 9, collected at baseline as well as one week (W1), W2, W3, W4 and W12 after baseline.

RESULTS

All scores showed a statistically significant improvement over time. The PSEQ and NRS scores showed a significant Time × Treatment effect. Patients treated with rESWT had significantly lower mean NRS values than patients treated with rESWT + C + E at W1 and W3, as well as than patients treated with C + E alone at W3 and W4. No severe adverse events were observed.

CONCLUSIONS

rESWT may not be inferior to respectively rESWT + C + E or C + E alone in reducing pain in patients with cnsLBP.

Extracorporeal Shockwave Therapy in the Management of Sports Medicine Injuries

ABSTRACT

Treatment of musculoskeletal conditions in athletes with extracorporeal shockwave therapy (ESWT) is gaining popularity as greater evidence supports its use. ESWT protocols (describing energy flux density, number of impulses, type of shockwave (focused or radial), number/frequency/duration of treatment session, area of application, and postprocedural therapy protocols) can be adjusted in the clinical setting. Protocols vary across studies, and optimal protocols for most indications are yet to be determined. ESWT can safely be used to treat various musculoskeletal conditions in athletes, including rotator cuff tendinopathy, lateral elbow epicondlyopathy, greater trochanteric pain syndrome, hamstring tendinopathy, patellar tendinopathy, Achilles tendinopathy, other tendinopathies, plantar fasciopathy, bone stress injuries, and medial tibial stress syndrome. ESWT can be used to treat in-season athletes, as it often requires no/minimal time away from sport and may result in rapid benefits. ESWT should be used in conjunction with physical therapy to facilitate longer-term gains in function and to optimize healing.

Biologics in the Treatment of Plantar Fasciitis

Plantar fasciitis has been considered an acute inflammatory disorder. However, the local histologic findings represent a more chronic, degenerative state without inflammation. Patients may be stuck in a chronic state of cyclical inflammation leading to tissue degeneration, refractory symptoms, and disability. This idea process has influenced the treatment approach of some practitioners who have implemented the idea of regenerative medicine and use of biologic adjuvants in the treatment of plantar heel pain. Biologic therapies provide many different cellular components, growth factors, and proteins to restore normal tissue biology and are a useful adjunct in the treatment of recalcitrant plantar fasciitis.

Extracorporeal Shock Wave Therapy Immediately Affects Achilles Tendon Structure and Widespread Pressure Pain Thresholds in Healthy People: A Repeated-Measures Observational Study

OBJECTIVE

Extracorporeal shockwave therapy is a common clinical treatment for tendinopathy, yet negative effects on tendon structure have been shown in animal studies. This study aimed to investigate the effect of extracorporeal shockwave therapy in healthy participants (i.e., no Achilles tendon pain or pathology).

DESIGN

This study examined the effect of three bouts of weekly extracorporeal shockwave therapy for 3 wks in 13 healthy participants. Outcomes measures assessed were as follows: (a) Achilles tendon structure, quantified using ultrasound tissue characterization (before and 3 hrs after extracorporeal shockwave therapy), (b) pressure pain thresholds, over the Achilles tendon and common extensor tendon origin (before, immediately after, and 3 hrs after extracorporeal shockwave therapy), and (c) hop pain (before and immediately after extracorporeal shockwave therapy).

RESULTS

There was a significant reduction in echo type I (P < 0.05) and increase in echo type II (P < 0.05) at 3 hrs after the first extracorporeal shockwave therapy session that recovered to baseline levels before week 2. There were no significant changes in ultrasound tissue characterization echo pattern observed in subsequent sessions. There were increased pressure pain thresholds immediately after extracorporeal shockwave therapy at the common extensor tendon origin but no significant change at the Achilles tendon. Pressure pain thresholds returned to baseline at 3 hrs after extracorporeal shockwave therapy. There were no significant changes in pressure pain threshold in subsequent sessions.

CONCLUSIONS

Extracorporeal shockwave therapy resulted in transient changes to tendon structure and widespread hyperalgesia.

[Differential diagnosis of heel pain]

"Heel pain" describes a very common reason for foot orthopedic consultation and the further differential diagnostic investigation is crucial for the choice of correct treatment. In the treatment of frequent underlying diseases, such as plantar fasciitis or insertional tendinopathy of the Achilles tendon, a variety of modern strategies are available. Rarer diseases, such as tumors or nerve entrapment syndromes must be delineated and correctly classified. This article provides the current state of the diagnostics and treatment of the most common entities of heel pathologies.

Extracorporeal Shock Wave Stimulates Angiogenesis and Collagen Production in Facial Soft Tissue

BACKGROUND

This study investigated the efficacy of extracorporeal shock wave (ESW) application in stimulating dermal thickness, vascularity, and collagen synthesis of facial skin in a large animal model.

MATERIALS AND METHODS

The facial skin of the maxillary and mandibular areas of goats (n = 6 per group) was treated with ESWs of different intensities (0.15 and 0.45 mJ/mm²; 1000 pulses). After 4 d, histology and immunohistochemistry were used to evaluate the following: dermal thickness, total number and abundance of microvessels, amount of type 1 collagen, and α-smooth muscle actin expression.

RESULTS

Dermal thickness, number and abundance of microvessels, and collagen synthesis increased after ESW application at both intensities (each P < 0.05). When comparing ESW groups, the highest collagen abundance was seen after 0.15 mJ/mm² (P = 0.034), whereas the highest number of microvessels was detected after treatment with 0.45 mJ/mm² (P = 0.002).

CONCLUSIONS

A single-session application of focused low-energy ESWs to facial skin can increase dermal thickness by stimulating collagen production and local microcirculation. These findings commend the technique for future investigation for pretreatment of local or microvascular skin flaps to enhance tissue healing.

American College of Foot and Ankle Surgeons Clinical Consensus Statement: Diagnosis and Treatment of Adult Acquired Infracalcaneal Heel Pain

Adult acquired inferior calcaneal heel pain is a common pathology seen in a foot and ankle practice. A literature review and expert panel discussion of the most common findings and treatment options are presented. Various diagnostic and treatment modalities are available to the practitioner. It is prudent to combine appropriate history and physical examination findings with patient-specific treatment modalities for optimum success. We present the most common diagnostic tools and treatment options, followed by a discussion of the appropriateness of each based on the published data and experience of the expert panel.

High- versus low-energy extracorporeal shock-wave therapy for myofascial pain syndrome of upper trapezius: A prospective randomized single blinded pilot study

BACKGROUND

To compare the efficacy of high- and low-energy extracorporeal shock wave therapy (ESWT) for patients with myofascial pain syndrome (MPS) of the upper trapezius.

METHODS

Thirty patients (3 men, 27 women) were randomly assigned to receive either high-energy ESWT (0.210 mJ/mm) or low-energy ESWT (0.068 mJ/mm). Both groups received 1500 pulses of ESWT once a week, for 2 weeks. Outcome measurement was assessed by verbal numeric pain scale (VNS), neck disability index (NDI), neck range of motion (ROM) (flexion, extension, rotation, lateral bending), and pressure threshold (PT). Statistical analysis was performed with significance level of P < .05.

RESULTS

No statistically significant differences of demographic and clinical characteristics existed between the 2 groups. VNS, NDI, neck ROM (rotation to sound side, lateral bending to affected side, lateral bending to sound side), and PT were improved in both groups. In contrast, statistically significant improvements in neck flexion and neck extension were observed only in the high-energy group. We also found significant differences in post-treatment NDI (4.20 ± 1.78 vs 6.47 ± 2.48) and post-treatment neck flexion ROM (65.47 ± 10.09 vs 55.93 ± 11.07) between high-energy and low-energy group.

CONCLUSION

ESWT effectively improves VNS, NDI, neck ROM, and PT to patients with MPS of the upper trapezius. High-energy ESWT was more effective in improving NDI and neck flexion ROM compared to the low-energy ESWT, suggesting superiority in functional improvement. Further studies are required to specify the effect of ESWT by energy intensity.

Effect of Shockwave Treatment for Management of Upper and Lower Extremity Musculoskeletal Conditions: A Narrative Review

Extracorporeal shockwave therapy (ESWT) is a technology that was first introduced into clinical practice in 1982 for urologic conditions. Subsequent clinical applications in musculoskeletal conditions have been described in treatment of plantar fasciopathy, both upper and lower extremity tendinopathies, greater trochanteric pain syndrome, medial tibial stress syndrome, management of nonunion fractures, and joint disease including avascular necrosis. The aim of this review is to summarize the current understanding of treatment of musculoskeletal conditions with ESWT, accounting for differences in treatment protocol and energy levels. Complications from ESWT are rare but include 2 reported cases of injury to bone and Achilles tendon rupture in older adults using focused shockwave. Collectively, studies suggest ESWT is generally well-tolerated treatment strategy for multiple musculoskeletal conditions commonly seen in clinical practice. LEVEL OF EVIDENCE: III.

Mean pretreatment VAS scores for the rESWT and control groups were 8.3 and 8.5, respectively. Three and 12 months after inclusion in the study, the mean VAS scores for the rESWT and control groups were 3.4 and 5.6 (P < 0.001) and 2.7 and 4.7 (P < 0.001), respectively. Twelve-month follow-up MQD-Sports and MQD-Work scores for the rESWT and control groups were 3.7 and 1.7 (P < 0.001) and 3.8 and 1.8 (P < 0.001), respectively. Differences in mean RM scores were statistically significant between groups at 3 months after the treatment. There were no significant complications.

CONCLUSIONS

Overall, rESWT is an effective and safe treatment for cDBT.

CLINICAL RELEVANCE

Radial ESWT as a novel, effective, and safe treatment for cDBT.

Extracorporeal Shockwave Therapy Versus Kinesiology Taping in the Management of Plantar Fasciitis: A Randomized Clinical Trial

Objectives

This study aims to compare the efficacy of extracorporeal shockwave therapy (ESWT) and kinesiology taping in the treatment of plantar fasciitis.

Patients and methods

The study included 80 patients diagnosed with plantar fasciitis. The patients were randomized into two groups as ESWT (9 males, 28 females; mean age 47.8±12.4 years; range 40 to 55 years) and kinesiology taping (KT, 7 males, 26 females; mean age 47.7±9.8 years; range 40 to 55 years) groups. Groups were similar regarding age, sex, and body mass index (all p>0.05). Three patients in ESWT group and seven patients in KT group were lost to follow-up. ESWT was applied once a week for five weeks, while KT was applied every five days for five weeks. Patients' pain and functional status were evaluated with visual analog scale, heel tenderness index, and foot and ankle outcome score before and after treatment.

Results

At the study onset, there were no statistically significant differences between the two groups in their visual analog scale, heel tenderness index, and foot and ankle outcome scores. Five weeks later, both groups showed significant improvement in all parameters (p<0.05), but no significant differences were observed between the groups in the visual analog scale, heel tenderness index, and foot and ankle outcome score scores.

Conclusion

Both ESWT and KT treatments improved pain levels and function and quality of life in individuals with plantar fasciitis. Neither method was superior in treating plantar fasciitis.

Low-energy versus middle-energy extracorporeal shockwave therapy for the treatment of snapping scapula bursitis

OBJECTIVE

Extracorporeal shockwave therapy (ESWT) has been used successfully in treatment of musculoskeletal disorders. Our objective was to assess the effectiveness of low versus middle-energy ESWT on snapping scapula bursitis.

METHODS

Thirty-five patients, divided into two groups, group (L), received low-energy ESWT, group (M) received middle-energy ESWT. Groups were evaluated at 1,3,6 and 12 months using the Visual Analogue Scale (VAS), the Constant-Murley scoring (CMS) and the Roles and Maudsley criteria.

RESULTS

In groups (L) and (M), VAS average values after 1,3,6 months and one year were (43±5.17, 38±4.33, 28±4.18 and 19±3.39) and (37±4.85, 26±4.74, 21±4.45 and 7±3.42) respectively. At six and twelve months, statistical difference was detected, P (0.034, 0.026) respectively. After one year of completing the treatment, the average values of CMS were (83.5±6.44 and 91±5.33) respectively, P=0.046. Roles and Maudsley criteria demonstrated that, patients in group (L), 6 (35%) excellent, 5 (29%) good, 4 (24%) acceptable and 2 (12%) had poor results. Whereas, patients in group (M), 11 (61%) excellent, 3 (17%) good, 3 (17%) acceptable and 1 (5%) had poor results.

CONCLUSION

Although low-energy ESWT showed good early-term results, but middle-energy ESWT protocol demonstrated better early-term, Mid-term, and late-term results.

Historical ESWT Paradigms Are Overcome: A Narrative Review

Extracorporeal Shock Wave Therapy (ESWT) is a conservative treatment modality with still growing interest in musculoskeletal disorders. This narrative review aims to present an overview covering 20-year development in the field of musculoskeletal ESWT. Eight historical paradigms have been identified and put under question from a current perspective: energy intensity, focus size, anesthesia, imaging, growth plates, acuteness, calcifications, and number of sessions. All paradigms as set in a historical consensus meeting in 1995 are to be revised. First, modern musculoskeletal ESWT is divided into focused and radial technology and the physical differences are about 100-fold with respect to the applied energy. Most lesions to be treated are easy to reach and clinical focusing plays a major role today. Lesion size is no longer a matter of concern. With the exception of nonunion fractures full, regional, or even local anesthesia is not helpful in musculoskeletal indications. Juvenile patients can also effectively be treated without risk of epiphyseal damage. Further research is needed to answer the question about if and which acute injuries can be managed effectively. Treatment parameters like the number of sessions are still relying on empirical data and have to be further elucidated.

Efficacy and safety of extracorporeal shock wave therapy for orthopedic conditions: a systematic review on studies listed in the PEDro database

BACKGROUND

Extracorporeal shock wave therapy (ESWT) is an effective and safe non-invasive treatment option for tendon and other pathologies of the musculoskeletal system.

SOURCES OF DATA

This systematic review used data derived from the Physiotherapy Evidence Database (PEDro; www.pedro.org.au, 23 October 2015, date last accessed).

AREAS OF AGREEMENT

ESWT is effective and safe. An optimum treatment protocol for ESWT appears to be three treatment sessions at 1-week intervals, with 2000 impulses per session and the highest energy flux density the patient can tolerate.

AREAS OF CONTROVERSY

The distinction between radial ESWT as 'low-energy ESWT' and focused ESWT as 'high-energy ESWT' is not correct and should be abandoned.

GROWING POINTS

There is no scientific evidence in favour of either radial ESWT or focused ESWT with respect to treatment outcome.

AREAS TIMELY FOR DEVELOPING RESEARCH

Future randomized controlled trials should primarily address systematic tests of the aforementioned optimum treatment protocol and direct comparisons between radial and focused ESWT.

Predictability of the individual clinical outcome of extracorporeal shock wave therapy for cellulite

BACKGROUND

Extracorporeal shock wave therapy has been successfully introduced for the treatment of cellulite in recent years. However, it is still unknown whether the individual clinical outcome of cellulite treatment with extracorporeal shock wave therapy can be predicted by the patient's individual cellulite grade at baseline, individual patient age, body mass index (BMI), weight, and/or height.

METHODS

Fourteen Caucasian females with cellulite were enrolled in a prospective, single-center, randomized, open-label Phase II study. The mean (± standard error of the mean) cellulite grade at baseline was 2.5±0.09 and mean BMI was 22.8±1.17. All patients were treated with radial extracorporeal shock waves using the Swiss DolorClast(®) device (Electro Medical Systems, S.A., Nyon, Switzerland). Patients were treated unilaterally with 2 weekly treatments for 4 weeks on a randomly selected side (left or right), totaling eight treatments on the selected side. Treatment was performed at 3.5-4.0 bar, with 15,000 impulses per session applied at 15 Hz. Impulses were homogeneously distributed over the posterior thigh and buttock area (resulting in 7,500 impulses per area). Treatment success was evaluated after the last treatment and 4 weeks later by clinical examination, photographic documentation, contact thermography, and patient satisfaction questionnaires.

RESULTS

The mean cellulite grade improved from 2.5±0.09 at baseline to 1.57±0.18 after the last treatment (ie, mean δ-1 was 0.93 cellulite grades) and 1.68±0.16 at follow-up (ie, mean δ-2 was 0.82 cellulite grades). Compared with baseline, no patient's condition worsened, the treatment was well tolerated, and no unwanted side effects were observed. No statistically significant (ie, P<0.05) correlation was found between individual values for δ-1 and δ-2 and cellulite grade at baseline, BMI, weight, height, or age.

CONCLUSION

Radial shock wave therapy is a safe and effective treatment option for cellulite. The individual clinical outcome cannot be predicted by the patient's individual cellulite grade at baseline, BMI, weight, height, or age.

Update on evidence-based treatments for plantar fasciopathy

Plantar fasciopathy, a common, painful condition of the foot, is often diagnosed by a musculoskeletal physiatrist in an outpatient practice setting. This focused review examines the most recent recommendations for the management of plantar fasciopathy in acute, subacute, and chronic phases. The evidence for treatment with various interventions is discussed, and suggestions for clinical care (along with the respective rationales for those therapies) are provided. The purpose of this review is to enable clinicians to make informed evidence-based decisions about the best available treatments for patients with any phase of plantar fasciopathy. Emerging technologies for the treatment of the condition are also addressed.

Treatment of chronic plantar fasciopathy with extracorporeal shock waves (review)

There is an increasing interest by doctors and patients in extracorporeal shock wave therapy (ESWT) for chronic plantar fasciopathy (PF), particularly in second generation radial extracorporeal shock wave therapy (RSWT). The present review aims at serving this interest by providing a comprehensive overview on physical and medical definitions of shock waves and a detailed assessment of the quality and significance of the randomized clinical trials published on ESWT and RSWT as it is used to treat chronic PF. Both ESWT and RSWT are safe, effective, and technically easy treatments for chronic PF. The main advantages of RSWT over ESWT are the lack of need for any anesthesia during the treatment and the demonstrated long-term treatment success (demonstrated at both 6 and 12 months after the first treatment using RSWT, compared to follow-up intervals of no more than 12 weeks after the first treatment using ESWT). In recent years, a greater understanding of the clinical outcomes in ESWT and RSWT for chronic PF has arisen in relationship not only in the design of studies, but also in procedure, energy level, and shock wave propagation. Either procedure should be considered for patients 18 years of age or older with chronic PF prior to surgical intervention.

Topical anaesthesia does not affect cutaneous vasomotor or sudomotor responses in human skin

(1) The effects of local sensory blockade (topical anaesthesia) on eccrine sweat glands and cutaneous circulation are not well understood. This study aimed to determine whether topical lidocaine/prilocaine alters eccrine sweat gland and cutaneous blood vessel responses. (2) Sweating (capacitance hygrometry) was induced via forearm intradermal microdialysis of five acetylcholine (ACh) doses (1 × 10(-4) to 1 × 10(0) m, 10-fold increments) in control and treated forearm sites in six healthy subjects. Nitric oxide-mediated vasodilatory (sodium nitroprusside) and adrenergic vasoconstrictor (noradrenaline) agonists were iontophoresed in lidocaine/prilocaine-treated and control forearm skin in nine healthy subjects during blood flow assessment (laser Doppler flowmetry, expressed as% from baseline cutaneous vascular conductance; CVC; flux/mean arterial pressure). (3) Non-linear regression curve fitting identified no change in the ED50 of ACh-induced sweating after sensory blockade (-1.42 ± 0.23 logM) compared to control (-1.27 ± 0.23 logM; P > .05) or in Emax (0.43 ± 0.08 with, 0.53 ± 0.16 mg cm(-2) min(-1) without lidocaine/prilocaine; P > .05). Sensory blockade did not alter the vasodilator response to sodium nitroprusside (1280 ± 548% change from baseline CVC with, 1204 ± 247% without lidocaine/prilocaine) or vasoconstrictor response to noradrenaline (-14 ± 4% change from baseline CVC with, -22 ± 14% without lidocaine/prilocaine; P > 0.05). (4) Cutaneous sensory blockade does not appear to alter nitric oxide-mediated vasodilation, adrenergic vasoconstriction, or cholinergic eccrine sweating dose-response sensitivity or responsiveness to maximal dose. Thus, lidocaine/prilocaine treatment should not affect sweat gland function or have blood flow implications for subsequent research protocols or clinical procedures.

Platelet-rich plasma versus focused shock waves in the treatment of jumper's knee in athletes

BACKGROUND

Tendinopathies represent a serious challenge for orthopaedic surgeons involved in treatment of athletes.

PURPOSE

To compare the effectiveness and safety of platelet-rich plasma (PRP) injections and focused extracorporeal shock wave therapy (ESWT) in athletes with jumper's knee.

STUDY DESIGN

Randomized controlled trial; Level of evidence, 1.

METHODS

Forty-six consecutive athletes with jumper's knee were selected for this study and randomized into 2 treatment groups: 2 autologous PRP injections over 2 weeks under ultrasound guidance (PRP group; n = 23), and 3 sessions of focused extracorporeal shock wave therapy (2.400 impulses at 0.17-0.25 mJ/mm(2) per session) (ESWT group; n = 23). The outcome measures were Victorian Institute of Sports Assessment-Patella (VISA-P) questionnaire, pain visual analog scale (VAS), and modified Blazina scale. A reviewer who was blinded as to the group allocation of participants performed outcome assessments before treatment and at 2, 6, and 12 months after treatment. Nonparametric tests were used for within-group (Friedman/Wilcoxon test) and between-group (Kruskal-Wallis/Fisher test) testing, and the significance level was set at .05.

RESULTS

The 2 groups were homogeneous in terms of age, sex, level of sports participation, and pretreatment clinical status. Patients in both groups showed statistically significant improvement of symptoms at all follow-up assessments. The VISA-P, VAS, and modified Blazina scale scores showed no significant differences between groups at 2-month follow-up (P = .635, .360, and .339, respectively). The PRP group showed significantly better improvement than the ESWT group in VISA-P, VAS scores at 6- and 12-month follow-up, and modified Blazina scale score at 12-month follow-up (P < .05 for all).

CONCLUSION

Therapeutic injections of PRP lead to better midterm clinical results compared with focused ESWT in the treatment of jumper's knee in athletes.

Clinical improvement and resorption of calcifications in calcific tendinitis of the shoulder after shock wave therapy at 6 months' follow-up: a systematic review and meta-analysis

OBJECTIVES

To evaluate the effectiveness of shock wave therapy (SWT) for functional improvement and the reduction of pain in patients with calcific tendinitis of the shoulder, and to determine the rate of disappearance of calcifications after therapy at 6 months' follow-up.

DATA SOURCES

Articles were searched from the Cochrane Library, MEDLINE, Embase, CINAHL, and Ovid database.

STUDY SELECTION

We included randomized controlled trials from 1992 to 2011, and their quality was assessed using the Physiotherapy Evidence Database (PEDro) scale.

DATA EXTRACTION

Studies were evaluated by 2 independent reviewers for their methodologic quality. Disagreements were settled by a third reviewer. Data were then extracted and cross-checked for accuracy. The reviewers were not blinded to the authors of the articles.

DATA SYNTHESIS

In 4 of the 6 studies included for review, the resorption of calcifications was evaluated using meta-analysis because the studies had 2 treatment groups, while the other 2 studies were analyzed descriptively because they had 3 treatment groups. Fixed- and random-effects models were used to meta-analyze total and partial resorption ratios, and I(2) statistics were calculated to assess heterogeneity.

CONCLUSIONS

We found a clinical improvement with a pooled total resorption ratio of 27.19 (95% confidence interval [CI], 7.20-102.67) and a pooled partial resorption ratio of 16.22 (95% CI, 3.33-79.01). SWT increases shoulder function, reduces pain, and is effective in dissolving calcifications. These results were maintained over the following 6 months.

Extracorporeal shock-wave therapy for supraspinatus calcifying tendinitis: a randomized clinical trial comparing two different energy levels

BACKGROUND

Extracorporeal shock-wave therapy (ESWT) represents a valid intervention in the treatment of people with supraspinatus calcifying tendinitis (SCT), but there is limited evidence for the useful range of ESWT doses.

OBJECTIVE

The aim of this study was to compare 2 different ranges of energy flux density in treatment of SCT with ESWT.

DESIGN

This study was designed as a single-blind randomized clinical trial.

SETTING

This study was performed in a university hospital.

PATIENTS

Forty-six patients with SCT were randomly assigned to 2 groups that received different therapeutic energy doses of ESWT: (1) group A received ESWT at an energy level of 0.20 mJ/mm², and (2) group B received ESWT at an energy level of 0.10 mJ/mm².

INTERVENTION

The treatment protocol consisted of 4 sessions performed once a week.

MEASUREMENTS

The change in mean Constant Murley Scale (CMS) scores at 3 and 6 months was the primary endpoint. The change in the mean visual analog scale (VAS) scores from baseline to 3 and 6 months after the intervention and radiographic change in size of calcium deposits were evaluated as secondary endpoints. At 12 months, pain relief was assessed using a numeric rating scale.

RESULTS

Significant clinical improvement based on mean CMS scores was observed after 6 months in group A (X=79.43, SD=10.33) compared with group B (X=57.91, SD=6.53). Likewise, after 6 months, a significant decrease in VAS scores was found in group A (X=2.09, SD=1.54) compared with group B (X=5.36, SD=0.78). Calcific deposits disappeared in the same percentage of patients in both groups.

LIMITATIONS

The small sample size and lack of a control group were limitations of the study.

CONCLUSIONS

In ESWT for SCT, an energy level of 0.20 mJ/mm² appears to be more effective than an energy level of 0.10 mJ/mm² in pain relief and functional improvement.
