Extracorporeal Shockwave for Intermittent Claudication and Quality of Life

Intermittent lower limb claudication limits function and quality of life. Supervised exercise programs are not readily available, and a noninvasive alternative is needed. To assess extracorporeal corporeal shockwave therapy in improving quality of life in patients with claudication. In this double-blind, placebo-controlled randomized clinical trial, patients in the outpatient setting at a single tertiary center for vascular surgery were randomized in a 1:1 ratio to extracorporeal shockwave therapy or placebo therapy with no shockwaves delivered. Recruitment was between June 2015 and January 2020, with 12-week follow-up ending in March 2020. A convenience sample of patients with claudication and conservative treatment requirements who refused or were unable to participate in supervised exercise were eligible. Patients receiving anticoagulation therapy or with an active cancer were excluded. Of 522 patients screened, 389 were eligible, 138 were enrolled, and 110 completed follow-up and were included in the primary analysis. Statistical analysis was completed by May 2021. In the intervention group, patients received 100 impulses of 0.1mJ/mm/cm2 in an area of the gastrocnemius muscle 3 times weekly for 3 weeks. The steps for treatment were replicated for the control group without delivering the treatment. The primary outcome was the Physical Functioning domain of the 36-item Short-Form Quality of Life Questionnaire at 12-week follow-up. Secondary outcomes included walking distances, ankle brachial pressure index, and other quality-of-life measures. Of 138 patients recruited and randomized, 92 (67%) were male, and the mean (SD) age of the study population was 67 (9.6) years. The intervention group had a significantly higher physical function score at 12 weeks (estimated median difference 3.8; 95% CI, 0.0-7.7; P = .03). However, this significance did not remain when adjusting for covariates. At 12 weeks, the intervention group had significantly longer pain-free and maximum walking distances (pain-free estimated median difference, 34.1, 95% CI, 11.4-56.8; P = .004; maximum estimated median difference, 51.4; 95% CI, 10.7-86.5; P = .01). To our knowledge, this is the first double-blind, placebo-controlled, randomized clinical trial to consider extracorporeal shockwave therapy for the management of intermittent claudication. It demonstrated efficacy for walking distances, may have a positive effect on quality of life, and may provide a safe, noninvasive alternative therapy for patients with intermittent claudication.

Extracorporeal Shockwave for Claudication—Potential Efficacy

Extracorporeal Shockwave for Claudication—Potential Efficacy

Does Radial Extracorporeal Shockwave Therapy Applied to the Achilles Tendon Influence Ankle Functionality?

This study aimed to determine the effectiveness of radial extracorporeal shockwave therapy (rESWT) in enhancing ankle function in patients with Achilles tendon injuries. The choice of rESWT was based on previous success in the treatment of musculoskeletal conditions. The study involved an intervention group that received rESWT, and a control group that received sham therapy. The results revealed that rESWT led to significant improvements in single-leg vertical jump (d = 0.55, p < 0.05), indicating enhanced power generation and ankle functionality that were not observed in the control group. Additionally, the therapy resulted in increased ankle mobility, as observed by improvements in plantar flexion and heel-rise tests. Interestingly, these functional gains were not accompanied by changes in the Achilles tendon stiffness, suggesting that the benefits of rESWT may be more functional than structural. This study highlights rESWT as a promising tool for rehabilitation, particularly following Achilles tendon injuries. The study concluded that, although rESWT appears to improve certain aspects of ankle function, further studies with a larger and more diverse population over a longer period are necessary to confirm these findings and establish comprehensive treatment protocols.

The Efficacy of Extracorporeal Shockwave Therapy Compared with Compression Therapy in Healing Venous Leg Ulcers.

Background: Innovative methods of physical therapy delivered via modern medical devices have significantly extended the possibility of applying conservative treatments in healing venous leg ulcers. The primary objective of this study was to compare the therapeutic efficacy of selected mechanical physical therapies (intermittent pneumatic compression vs. radial extracorporeal shockwave vs. focal extracorporeal shockwave) vs. standard care in the treatment of venous leg ulcers over a 4-week period. Materials: This study included 69 patients, comprising 45 females (65%) and 24 males (35%), with a mean age of 67.1 ± 8.6 years (range: from 52.0 to 80.0 years). Methods: The patients were allocated into four groups: the IPC group was treated with intermittent pneumatic compression therapy, the R-ESWT group was treated with radial extracorporeal shockwave therapy, the F-ESWT group was treated with focal extracorporeal shockwave therapy, and the SC group was treated with standard care. Results: After one month of therapy, the median percentage decrease in wound total surface area after treatment was as follows: in the IPC group, there was a 52.9% decrease (range: 3.3-100%); in the R-ESWT group, there was a 31.6% decrease (range: 2.4-95.8%); in the F-ESWT group, there was an 18.0% decrease (range: 1.9-76.1%); and in the SC group, there was a 16.0% decrease (range: 1.5-45.8%). Conclusions: All the studied therapies caused a statistically significant reduction in the surface area of venous leg ulcers. The best results were observed with the intermittent pneumatic compression, while the radial and focal extracorporeal shockwave therapies appeared less effective. The standard care alone turned out to be the least effective. Our results did not show statistically significant changes in the values of RBC deformability at the investigated shear rates.

Effectiveness of Rehabilitation for Osteoarthritis of the Knee: A Scoping Review of Network Meta-Analyses.

Although an increasing number of network meta-analyses have been conducted on the effectiveness of conservative therapy for knee osteoarthritis, these may have been poorly planned and executed.We aimed to review the qualities of a comprehensive set of network meta-analyses on rehabilitation therapies for knee osteoarthritis and provide an overview of the effectiveness of each therapy. The eligibility criteria were as follows: (i) conservative rehabilitation was the primary treatment in the intervention group, (ii) included patients were diagnosed with knee osteoarthritis, and (iii) patient groups were aged ≤75 years, and rehabilitation interventions comprised exercise, orthotic, or physical therapies or patient education. Two independent reviewers screened the titles and abstracts of the identified records and selected the eligible reviews; their full texts were further assessed for eligibility. Then, a checklist derived from the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) extension statement for the reporting of systematic reviews incorporating network meta-analyses of healthcare Interventions was used to validate the completeness of the reporting of each network meta-analysis. Furthermore, the statistical and outcome data regarding the quality of life, knee joint function and pain, adverse events, and physical functions were extracted using a customized spreadsheet. Overall, 2701 titles and abstracts were screened, and eight network meta-analyses were ultimately selected. Nearly all reviews adequately addressed the PRISMA extension checklist, and the completeness of reporting was adequate; therefore, all expected information could be extracted. However, the methodology used to confirm the transitivity assumption was insufficient in many reviews. The following interventions were effective in reducing pain and improving physical function: (i) strengthening, flexibility, aerobic, and mind-body exercises, (ii) pulsed ultrasound, (iii) focused and radial extracorporeal shockwave therapy, and (iv) continuous ultrasound. The following interventions were effective in improving the quality of life: (i) strengthening, (ii) mixed, and (iii) mind-body exercises. Our results suggested that exercise therapies, including muscle-strengthening, aerobic, flexibility, and mind-body exercises, are likely to be effective for pain relief and functional improvement in knee osteoarthritis. This may be the first review to provide a comprehensive perspective for considering priorities for future rehabilitation interventions for knee osteoarthritis.

Radiometry in a comprehensive assessment of the effectiveness of extracorporeal shock wave therapy of calcifying tendinobursopathy of the shoulder

Introduction. Uncomfortable working conditions and excessive professional loads on the shoulder joints cause a high prevalence of degenerative-dystrophic changes in the periarticular tissues. Calcifying tendinitis and bursitis occupy a special place, characterized by multifocal accumulation of calcium phosphate crystals in tendons, mucous bags and muscles. The study is devoted to solving the problem of optimizing the X-ray diagnostics of the evolution of calcifying tendinobursopathy of the shoulder (CTS) in the dynamic assessment of the effectiveness of extracorporeal shock wave therapy.&#x0D; The aims of the study to optimize the X–ray diagnosis of calcifying tendinobursopathy of the shoulder in people working under the influence of adverse production factors.&#x0D; Materials and methods. The authors conducted a comparative retrospective analysis of the results of a comprehensive dynamic clinical and X-ray examination of 155 able-bodied men aged 35-57 years with an average work experience of 14.5±2.7 years (miners, loaders, bricklayers) examined for pain syndrome and dysfunction in the shoulder joint. The main group (65 people) are patients with CTS clinic, the presence of calcifications in the periaricular tissues of the rotator cuff and in the biceps muscle of the shoulder, evaluated in dynamics after shock wave therapy (SWT) of the shoulder in the phases of rest, resorption and recovery. The comparison group (90 people) consisted of patients with the absence of instrumentally detectable signs of multifocal accumulation of calcium phosphate crystals in the periarticular tissues of the shoulder. The study included patients whose routine conservative treatment proved ineffective. The following criteria for the effectiveness of therapy were identified: pain at rest, measured using a visual analog scale (VAS); dimensions (calcification area (in mm2)); optical density and calcification density gradient. Specialists evaluated the data at the initial stage of the study before the use of therapy, immediately after treatment and 12 months after the final SWT session.&#x0D; Results. In patients of the main group with the presence of CTS, the main manifestations of shoulder-scapular periarthritis (SSP) both in the main group and in the comparison group were moderately pronounced, however, the frequency of detection of the main SSP syndromes, primarily rotator cuff lesion, as well as background pathology (arthrosis of the shoulder joint) and acromioclavicular joint) were significantly higher in the main group. The effectiveness of SWT was demonstrated by regression of pain syndrome and positive dynamics of density characteristics of periarticular tissues of shoulder joints in areas of interest (in anatomotopographic projections of localization of tendons, mucous bags and muscles). In all patients of the main group, the decalcification process was characterized by both a visually perceptible pattern of disintegration and a decrease in its area, and a decrease in optical density immediately after the end of treatment. In 36.9% of patients, 12 months after the start of SWT, the X-ray and X-ray densitometric picture confirmed the prolongation of the decalcification process up to complete lysis of foci and calcification sites.&#x0D; Conclusions. In a comprehensive assessment of the effectiveness of CTS therapy, along with traditional X-ray diagnostics, special methodological techniques of radiometry (X-ray diffraction and X-ray densitometry in areas of interest) can be used, allowing for more accurate and more objective reflection of the direction of the dynamics of changes.&#x0D; The use of X-ray calcifications in the arsenal of methodological techniques, such as area, optical density and optical density gradient, can significantly improve the quality of diagnosis and avoid the use of computed tomography and an increase in radiation exposure to the patient.&#x0D; High-energy extracorporeal shockwave therapy is largely able to solve the problem of treating resistant forms of calcifying tendinobursopathy of the shoulder.

Efficacy of Rehabilitative Techniques on Pain Relief in Patients With Vulvodynia: A Systematic Review and Meta-Analysis.

Vulvodynia is a chronic clinical condition characterized by provoked or non-provoked vulvar pain for at least 3months of unknown etiology. The onset of vulvodynia involves a complex interplay of peripheral and central pain mechanisms, such as pelvic floor muscle and autonomic dysfunction, and interpersonal factors. A stepwise approach of pelvic floor physical therapy as medical management is suggested. In this scenario, by this meta-analysis of randomized controlled trials, we aimed to evaluate the efficacy of rehabilitation interventions in patients with vulvodynia. On October 13, 2022, PubMed, Scopus, and Web of Science were systematically searched for randomized controlled trials that assessed the efficacy of the rehabilitative approach to pain during intercourse in patients with vulvodynia. The quality assessment was performed with the Cochrane risk-of-bias tool for randomized trials. The trial registration number is CRD42021257449. At the end of the search, 9 studies were included for a total of 332 patients. A pairwise meta-analysis was performed to highlight the efficacy of rehabilitative approaches for reducing pain during intercourse, as measured with a visual analog scale or a numerical rating scale. Meta-analysis showed that all these rehabilitative approaches had an overall effect size of -1.43 (95% CI = -2.69to -0.17) in decreasing vulvodynia pain in terms of the visual analog scale. In the subgroup analysis, a significant effect size in acupuncture (effect size = -2.36; 95% CI = -3.83 to -0.89) and extracorporeal shockwave therapy (effect size = -2.94; 95% CI = -4.31 to -1.57; I2= 58%) was observed. According to the Cochrane risk-of-bias tool, a low risk of bias for outcome selection in 89% of studies. Findings from this meta-analysis suggested that the physical agent modalities and complementary medicine techniques in people with vulvodynia appear to be more effective than placebo, sham, or waiting list. Further evidence on physical agent modalities and complementary therapies are warranted in the future. This was the first systematic review and meta-analysis of randomized controlled trials to provide evidence on the efficacy of rehabilitation interventions in patients with vulvodynia.

449 The Efficiency of Non-surgical Therapies for the Treatment of Mortons Neuroma: A Systematic Review

INTRODUCTION: Morton’s neuroma or Intermetatarsal neuroma is a benign inflammation of the peripheral nerves in the feet causing sharp, burning metatarsalgia and significant morbidity while walking, running, etc. It occurs more in females because tight shoe styles put pressure on the nerve. METHODS: Keyword search of “Morton’s Neuroma”, “treatment”, “conservative” and “non-surgical” was conducted across MEDLINE, EMBASE, and Cochrane databases. Two cohort studies and seven Randomised Controlled Trials were included for review following PRISMA guidelines. These studies were reviewed for pain relief, functionality, and limitations of each procedure. RESULTS: Methylprednisolone injections were proved to reduce the Visual Analog Scale score with &gt;50% cases showing no difficulty in functional daily activity at 9 months post-procedure. Short-term relief was achieved by alcohol and capsaicin injections independently. Modifications in the shoe insole indicated better functionality and analgesia compared to a flat insole but combined with steroids it showed better outcomes. Extracorporeal shockwave therapy provided relief for up to 3 months compared to radiofrequency ablation which provided relief for a longer period. CONCLUSIONS: Although these procedures show statistically significant changes, they are not without limitations. Well-designed randomized controlled trials looking into the avenues for radiofrequency ablation and shockwave therapies as opposed to surgical excision of neuromas are vital.

Efficacy and safety of extracorporeal shock wave therapy combined with sodium hyaluronate in treatment of knee osteoarthritis: a systematic review and Meta-analysis.

To assess the efficacy and safety of extracorporeal shockwave therapy (ESWT) combined with sodium hyaluronate (HA) for the treatment of knee osteoarthritis (KOA). PubMed, Embase, the Cochrane Library, Web of Science, China National Knowledge Infrastructure, Wanfang database, China Science and Technology Journal Database, and SinoMed were searched from inception to July 2020. The quality of the randomized controlled trials was evaluated independently by two reviewers according to the criteria in the Cochrane Collaboration for Systematic Reviews. The identified articles were then screened individually using EndnoteX9 for eligibility in this Meta-analysis. The heterogeneity among the articles was evaluated using I2. A total of 17 studies, comprising 2000 individuals, were included in this Meta-analysis. The results showed that a significant improvement was observed in knee pain and function based on the clinical efficacy of ESWT combined with HA. Statistical analysis of clinical efficacy showed that [relative risk (RR) = 1.21, 95% confidence interval (CI) (1.12, 1.30), P < 0.01]. Statistical analysis of visual analog scale showed that [standardized mean difference (SMD) = －2.84, 95%CI (－4.01, －1.66), P < 0.01]. Western Ontario and McMaster University osteoarthritis index statistical analysis showed that [SMD = －1.57, 95% CI (－2.52, －0.61), P < 0.01]. Lysholm score statistical analysis showed that [SMD = 1.71, 95% CI (0.98, 2.44), P < 0.01]. In addition, only minor side effects, such as redness and swelling of the skin, were observed. Medium to low quality evidence showed that ESWT combined with HA offers an inexpensive, well-tolerated, safe, and effective method to improve pain and functionality in patients with KOA. However, tightly controlled, randomized, large multicenter trials are warranted to validate the current findings.

Extracorporeal Shockwave Treatment as Additional Therapy in Patients with Post-Stroke Spasticity of Upper Limb-A Narrative Review.

Stroke is a severe injury of the central nervous system (CNS) and one of the leading causes of long-term disability and mortality. One of the main symptoms of neurological diseases is spasticity. This is defined as a motor condition characterized by a velocity-dependent increase in tonic stretch reflexes with exaggerated tendon jerks and resulting in the hyperexcitability of the stretch reflex. Rehabilitation after a stroke is focused on relearning lost skills and regaining independence. Many new methods in neurorehabilitation have been introduced. This review concentrates on the current evidence for extracorporeal shockwave therapy (ESWT) as a noninvasive alternative to treat spasticity. We present the effect of EWST and radial EWST interventions to post-stroke patients with spasticity in the upper limb. Our collected data suggest that different parameters of shockwaves can be used to achieve functional improvementsin the upper limb after a stroke. Our accumulated data imply that ESWT is safe and can be used for pain relief, reduced muscle tension, and an increased range of motion. According to many studies, complications after shockwave treatment are infrequent. Transient complications after shockwave therapy (ESWT) include redness, tingling, pain, and bruising. We reviewed clinical trials that present the possible benefits in upper-limb function after shockwave therapy for post-stroke patients. In this article, we used many database search engines, including PEDro. In the stroke rehabilitation literature, a key methodological problem is the design of double-blind studies, which very often are not feasible.

The role of manual correction methods and extracorporeal shock wave therapy in the prevention of chronic tension headaches

Introduction. Tension-type headache is an urgent problem in the modern medicine due to a significant decrease in the efficiency and quality of patient′s life, despite the benign nature of the disease.The aim of the study is to develop and scientifically substantiate the comprehensive application of extracorporeal shock wave therapy and manual methods of preventive treatment of the chronic tension-type headache.Materials and methods. The prospective randomized study included 90 patients with tension-type headache (chronic), G44.2, and 20 healthy patients in the age from 24 to 50 years. Participants were divided into 3 equal groups with 30 participants in each one. In the I group the pharmacotherapy with amitriptyline was performed, in the II group — manual treatment, and in the III group — complex rehabilitation with manual methods of treatment and extracorporeal shockwave therapy. Additionally, 20 healthy patients were included in the study (group IV). To assess the treatment effectiveness the following methods were used: a headache diary, manual examination, NRS scale, HADS scale.Results. The data obtained demonstrated that the combined use of manual treatment and extracorporeal shock wave therapy, as well as single-impact manual treatment methods, contributes to clinical improvement to a greater extent than pharmacotherapy. A comparative analysis of the study groups in the long-term follow-up period (after 3 months) showed more significant results in the group with comprehensive rehabilitation, which is clearly reflected in the form of a significant decrease in pain intensity and overall pain score. The methods used significantly improved the psycho-emotional status of patients, however, pharmacotherapy with amitriptyline was accompanied by side effects.Conclusion. The comprehensive application of extracorporeal shock wave therapy and manual methods of treatment leads to a significant improvement in both clinical and psycho-emotional states of patients with tension-type headache.

A novel shockwave-driven nano-motor composite microneedle transdermal delivery system for the localized treatment of osteoporosis: a basic science study.

Clinical protocols in osteoporosis treatment could not meet the requirement of increasing local bone mineral density. A local delivery system was brought in to fix this dilemma. The high-energy extracorporeal shock wave (ESW) can travel into the deep tissues with little heat loss. Hence, ESW-driven nanoparticles could be used for local treatment of osteoporosis. An extracorporeal shock wave (ESW)--actuated nanomotor (NM) sealed into microneedles (MN) (ESW-NM-MN) was constructed for localized osteoporosis protection. The NM was made of calcium phosphate nanoparticles with a high Young's modulus, which allows it to absorb ESW energy efficiently and convert it into kinetic energy for solid tissue penetration. Zoledronic (ZOL), as an alternative phosphorus source, forms the backbone of the NM (ZOL-NM), leading to bone targeting and ESW-mediated drug release. After the ZOL-NM is sealed into hyaluronic acid (HA)--made microneedles, the soluble MN tips could break through the stratum corneum, injecting the ZOL-NM into the skin. As soon as the ESW was applied, the ZOL-NM would absorb the ESW energy to move from the outer layer of skin into the deep tissue and be fragmented to release ZOL and Ca2+ for anti-osteoclastogenesis and pro-osteogenesis. In vivo, the ZOL-NM increases localized bone parameters and reduces fracture risk, indicating its potential value in osteoporotic healing and other biomedical fields. The ESW-mediated transdermal delivery platform (ESW-NM-MN) could be used as a new strategy to improve local BMD and protect local prone-fracture areas.

Extracorporeal Shockwave Therapy (ESWT), a Novel Method for Transferring Oral Implant Primary Failures to Final Clinical Success: A Test Case Report Followed up over More than 6 Years.

To evaluate the feasibility of reversing a primary failure through therapeutic mechanical stimulation induced by transcutaneous application of acoustic waves (ESWT) in the peri-implant tissues. Materials and Μethods: This clinical report evaluates the outcome of a new protocol proposed to treat a primary failure (loosened oral implant); application of three cycles of ESWT, once session per week for 3 consecutive weeks, with an equivalent positive energy of 0,18 mJ/mm² (therapeutic dose: 2000 impulses/ 8Hz/ 4.0 bar). Standardized intraoral radiographs, Cone Beam Computed Tomography (CBCT), Implant Stability Quotient (ISQ) and clinical evaluations were performed. It was possible to verify a progressive increase in the ISQ value after the ESWT protocol; 17 (initial), 46 (after two months) and 68 (after four months), which led to successful implant prosthetic rehabilitation (35 N/cm measured). Our evaluation at 6 years of follow-up confirms that the new bone-implant interface is preserved and ESWT as a safe non-invasive treatment. In the context of the new dynamic model of osseointegration, the Foreign Body Equilibrium (FBE), this represents the first report of a host-Implant equilibrium re-established after an early failure process. However, it is necessary to perform studies to determine both the medical device and the most effective therapeutic range for clinical applications of this technology in oral implantology.

O17: ‘I had to do something’: A qualitative study of patients and healthcare professionals engagement in an interventional diabetic foot ulcer trial

Abstract Background Development of interventions to improve diabetic foot ulcer(DFU) healing is vital, however trials typically under-recruit and translation of effective interventions is limited. This study explores patient and clinician perceptions of Extracorporeal Shockwave Therapy(ESWT) and the SOLEFUL Trial(randomised control trial of ESWT for DFU). Methods Maximum variable sampling technique was used to recruit participants from one tertiary centre and clinicians nationally. Semi-structured interviews were conducted, audio-recorded and transcribed verbatim in four participant groups (participants, dropouts, decliners, and clinicians). Data were analysed with an inductive exploratory approach using reflexive thematic analysis. Results 18 participants, 1 dropout, 3 decliners and 10 clinicians took part. Drivers for participation included desperation for healing and curiosity in a new intervention. Participants perceived the trial offered holistic healthcare, referencing quality-of-life questionnaires and telephone follow-ups. ESWT was viewed as hassle-free and painless, compared to alternatives. Barriers to participation included impact of competing comorbidities and belief care cannot be improved. In contrast, clinicians discussed mechanisms of action, effectiveness, and implementation of new technologies. Conclusion This study highlighted key drivers for trial engagement/disengagement in patients with DFUs and their clinicians. These factors must be respected in trial design and delivery to aid successful development of new DFU interventions.

The Potential for Foreign Body Reaction of Implanted Poly-L-Lactic Acid: A Systematic Review.

Poly-L-lactic acid (PLLA) implants have been used for bone fixation for decades. However, upon insertion, they can cause a foreign body reaction (FBR) that may lead to complications. On 15 December 2023, a systematic review was conducted to search for articles on the PubMed, MeSH term, and Scopus databases using the keywords 'PLLA' and 'foreign body reaction'. The articles were reviewed not only for the question of FBR, its severity, and the manifestation of symptoms but also for the type of implant and its location in the body, the species, and the number of individuals included. A total of 71 original articles were identified. Of these, two-thirds reported on in vivo trials, and one-third reported on clinical applications. The overall majority of the reactions were mild in more than half of the investigations. Symptoms of extreme and extensive FBR mainly include osteolysis, ganglion cysts, and swelling. The localization of PLLA implants in bone can often result in osteolysis due to local acidosis. This issue can be mitigated by adding hydroxyapatite. There should be no strong FBR when PLLA is fragmented to 0.5-4 µm by extracorporeal shock wave.

Rehabilitation in adults with burn injury: an overview of systematic reviews

Purpose To systematically evaluate evidence from published systematic reviews for the effectiveness of rehabilitation interventions in adults with burn injury. Materials and methods A comprehensive literature review conducted using medical and health science electronic databases up to 31 July 2022. Two independent reviewers selected studies, extracted data, and assessed methodological study quality using A Measurement Tool to Assess Systematic Reviews (AMSTAR-2), and the certainty of evidence for reported outcomes using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) tool. Results Twenty-one systematic reviews evaluated five categories of interventions: physical, psychological, technology-aided modalities, educational and occupational programs, complementary and alternative medicine. Outcomes included fitness level, hand function, oedema, pain, pruritus, psychological state, quality of life, range of motion, return to work, strength, scar characteristics, level of impairment and burn knowledge. The methodological quality was rated as “critically low” for all reviews. Quality of evidence for the effectiveness of evaluated interventions ranged from “moderate to very low.” Conclusions Beneficial effects of inhaled aromatherapy and extracorporeal shockwave therapy on pain reduction; inhaled or massage aromatherapy, music therapy on anxiety were reported. Safety of interventions was not evaluated, due to the lack of adverse event reporting in primary studies and the included reviews.

LOW-INTENSITY SHOCKWAVE TREATMENT FOR NEUROGENIC BLADDER WITH CHRONIC URINE RETENTION - CASE REPORT

We present a case of neurogenic bladder accompanied by chronic urine retention in a patient diagnosed with multiple sclerosis (MS). This condition was effectively managed by low-intensity shockwave therapy (Li-ESWT). Low-intensity focused shockwave therapy (Li-ESWT) is becoming increasingly important in the treatment of urological problems. This case study investigates the feasibility and efficacy of using Li-ESWT to reduce post-void residual volume in persons with neurogenic bladder, representing the first examination of its sort. Bladder dysfunction (BD) frequently occurs in patients who have been diagnosed with multiple sclerosis (MS). Bladder dysfunction (BD) can occur due to the impairment of nerve impulses in the central nervous system regions involved for regulating bladder function and managing the contractions of the urinary sphincters, which is caused by the lesions associated with multiple sclerosis (MS). Urinary retention can cause various symptoms, including insufficient bladder emptying, urinary incontinence, frequent urinary tract infections, urosepsis resulting in the development of kidney abscesses due to localised kidney infection, and reduced kidney function. Optimal bladder function is essential for individuals with MS, as it plays a critical role in preserving kidney health, preventing urinary tract infections and incontinence, reducing the frequency of MS episodes, and improving their overall well-being. A 31-year-old woman was referred to our urology office with a chronic urinary tract infection caused by a neurogenic bladder with a significant volume of residual urine. A kidney abscess formation was identified as a complication. Li-ESWT, which stands for low-intensity extracorporeal shockwave therapy, was used as a part of a multimodal strategy to treat the urinary bladder. This treatment was delivered off-label. The therapy was given on a weekly basis for a period of 6 weeks. The procedure included administering 2500 shocks at a rate of four pulses per second, with an energy flux density (EFD) of 0.25 millijoules per square millimetre. The EFD (Energy Flux Density) used in our study exceeded 0.32 mJmm2,4, the fR (frequency rate) was set at 8 Hz (pulses per second), the treatment sessions consisted of 12 cycles of Li-ESWT (Low-Intensity Extracorporeal Shockwave Therapy), and a total of 3000 shocks were administered. At the intervals of one week, three months, six months, nine months, and twelve months following the administration of Li-ESWT and tadalafil 2.5 mg, the post-void residual (PVR) volume was consistently below 50 ml. The Li-ESWT treatment effectively reduced the post-void residual urine volume.Low-intensity extracorporeal shockwave therapy (Li-ESWT) can safely and efficiently decrease the amount of urine left in the bladder after voiding in individuals with neurogenic bladder caused by multiple sclerosis (MS). We have effectively demonstrated that Li-ESWT is a feasible and safe treatment for chronic urine retention, resulting in a decrease of post-void residual (PVR) volume from 200 ml to 50 ml. In the future, Li-ESWT has the potential to be advanced as a more efficacious alternative therapy for individuals experiencing chronic urinary retention. Further investigation is necessary to confirm the effectiveness of ESWT in addressing the neurogenic bladder.

Impact of low-intensity extracorporeal shockwave therapy on vascular parameters and sexual function in patients with arteriogenic erectile dysfunction.

Previous published studies have shown an improvement of penile hemodynamic parameters after low-intensity extracorporeal shockwave therapy (Li-ESWT). However, the clinical significance of these findings remains unclear, and definitive selection criteria for Li-ESWT based on preexisting comorbidities have yet to be established. This was an observational study of 113 patients with ED, evaluated between January 2019 and December 2021 in Andrology Unit at the Department of Urology and Renal Transplantation, University of Foggia (Foggia, Italy). Penile dynamic Doppler was performed to evaluate vascular parameters and 5-item version of the International Index of Erectile Dysfunction (IIEF-5) questionnaire was administered to assess the severity of ED. This was repeated 1 month after treatment. Patients with a peak systolic velocity (PSV) <30 cm s -1 were considered eligible for Li-ESWT. Our protocol consisted of 8 weekly sessions with 1500 strokes distributed in 5 different locations along the penis. After treatment, a significant mean (±standard deviation [s.d.]) PSV increase of 5.0 (±3.4) cm s -1 was recorded and 52/113 (46.0%) patients reached a PSV >30 cm s -1 at posttherapeutic penile dynamic Doppler. A clinically significant IIEF-5 score improvement was observed in 7 patients, 21 patients, and 2 patients with mild-to-moderate, moderate, and severe pretreatment ED, respectively. No different outcomes were assessed based on smoking habits, previous pelvic surgery, or use of oral phosphodiesterase-5 inhibitor (PDE5i). On the other side, only 1 (6.7%) in 15 patients with diabetes mellitus showed an IIEF-5 score improvement after Li-ESWT. Shockwave treatment determined a significant increase in PSV and correlated IIEF-5 improvement in ED patients. This advantage seemed particularly evident for moderate ED and was not affected by smoking habits, previous pelvic surgery, and use of PDE5i. Conversely, diabetic patients did not benefit from the treatment.

(138) Efficacy and Patient Satisfaction of Low-Intensity Shockwave Treatment for Erectile Dysfunction in a Retrospective Real-World Study in Japan

Abstract Introduction In Japan, the treatment options for erectile dysfunction (ED) are very restricted, if phosphodiesterase type 5 inhibitors (PDE5Is) are not effective. In this situation, low-intensity extracorporeal shockwave therapy (LiESWT) has gained increased attention as a new option for ED treatment in Japan. Objective To clarify the efficacy of low-intensity extracorporeal shockwave therapy for patients with erectile dysfunction, compare the efficacy between two types of lithotripters (ED1000 [focused type] and Renova [linear type]), and detect factors indicative of therapeutic gain with the treatment. Methods This retrospective study included 76 patients (52.8 +/- 11.7 years) treated by ED1000 (12 times over 9 weeks) and 484 patients (52.5 +/- 11.6 years) treated by Renova (4 times over 4 weeks). Age, sexual symptoms scores, and blood examinations were assessed. Efficacy was judged by improvement of the scores and patient satisfaction and compared between patients at 1 month after treatment with the lithotripters. Independent factors influencing efficacy by Renova were also assessed. Results Sexual symptom scores were improved significantly by both lithotripters, although the changes in the scores did not differ significantly between them. Efficacy rate as judged by patient satisfaction was 65.8% with the ED1000 and 71.1% with Renova, also without significant difference. Among several factors including age, sexual symptoms scores, endocrinological factors, metabolic factors, and the rate of phosphodiesterase type 5 inhibitor use, only age was found to be an independent factor influencing the efficacy of Renova. Conclusions We clearly showed the high efficacy of both lithotripters. Although the efficacy rate did not differ between them, we speculated that the fewer treatment sessions needed with the Renova versus the ED1000 would be a great advantage for patients. We also suggest that Renova should be recommended for patients younger than 70 years of age. Disclosure No.

(281) Low-Intensity Shockwave Therapy Combined with Tadalafil 5mg Daily has Better Efficacy for Mild and Moderate Erectile Dysfunction: The Preliminary Results of a Multicenter Clinical Study in China

Abstract Introduction Most clinical studies have demonstrated that low-intensity extracorporeal shockwave therapy (Li-ESWT) can improved erectile function in patients with erectile dysfunction (ED). The EAU guideline recommended to use Li-ESWT for mild vasculogenic ED patients. However, the therapeutic advantages of Li-ESWT combined with phosphodiesterase type 5 inhibitors (PDE5i) have not been explored clearly in clinical practice for mild and moderate ED patients. Objective To compare the therapeutic effects of Li-ESWT and Li-ESWT combined with PDE5i in mild and moderate ED patients with 8≤IIEF-5≤16 from a multicenter clinical study in China. Methods Patients with ED which IIEF-5 score is less than 22 and aged 18–60 years old were enrolled from three clinical centers from Jun. 2019 to Mar. 2023. The demographic data, International Index of Erectile Function-5 (IIEF-5), erectile hardness score (EHS) and self-reported symptom questions were collected. Patients were treated by a linear low-energy shock waves generator (Renova). Low-intensity shock wave (energy density of 0.09mJ/mm2) treatments were applied (once a week, 4 weeks in total, 5000 shocks each time). Patients in Li-ESWT combined with PDE5i group took 5mg of tadalafil once a day for one continuous month during ESWT. Comparative analyses of pre- and post-treatment and intergroup were used for statistics. Results In total, 42 ED cases (37.43±11.86 years) in Li-ESWT group and 116 cases (37.41±10.14 years) in combined group were enrolled for analysis. The IIEF-5 score and EHS in both groups were significantly improved after 1 month treatment (p&amp;lt;0.01). Compared with Li-ESWT group, patients in combined group significantly had higher self-reported efficiency (61.2% vs. 47.6%, p=0.013), IIEF-5 scores (15.34±7.15 vs. 13.96±7.71, p=0.039) and EHS (2.85±0.82 vs. 2.69±0.89, p=0.050). In the mild and moderate ED (with 8≤IIEF-5≤16) sub-group, 30 ED cases (36.81±10.99 years) in Li-ESWT group and 96 cases (36.80±10.69 years) in combined group were enrolled for analysis. The combined regimen showed better therapeutic advantages, including effective parameters IIEF-5(14.50±6.74 vs. 12.87±8.54, p=0.040), EHS (2.85±0.75 vs. 2.81±0.67, p=0.046) and self-reported efficiency (64.2% vs. 54.1%, p=0.001). Conclusions Li-ESWT can effectively improve erectile function in this multicenter clinical study in China, and the combination of Li-ESWT with daily use PDE5i had a better therapeutic effect on Chinese ED patients, especially on mild and moderate ED. Long-term follow-up with large sample study need to be developed for exploring the optimal therapeutic regimen. Disclosure No.
