식약처에서 허가된 국내 11개 및 국외 6개 제조사의 46개 탄도형 체외 충격파 치료기 중 기술 문서가 공개된 15개 제품 70개의 충격파 발생 장치에 대해 충격파 음향 출력을 조사했다. 조사 결과, 임상에서 가장 보편적인 피폭 변수로 사용되는 에너지 속 밀도(Energy Flux Density, EFD)는 치료기의 충격파 발생 장치에 따라 최소 출력 설정에서 최대 563.64배, 최대 출력 설정에서 최대 74.62배까지 차이가 나고 있다. 동일 모델 제품에서 충격파 변환자의 선택으로 EFD의 값은 최소 설정에서 최대 81.82배, 최대 설정에서 최대 46.15배 차이를 보이고 있다. 최대 출력 설정에서 EFD의 최저값 0.013 mJ/mm²이 최소 출력 설정에서 EFD의 최대값 0.62 mJ/mm²보다 훨씬 낮은 것(2.1 %)으로 나타났다. 동일한 적응증으로 허가 받은 탄도형 체외 충격파 치료기의 음향 출력이 수십~수백 배 차이가 난다는 것은 치료기의 치료 효과 및 안전성을 보증하기 어렵다는 것을 시사한다. 본 연구의 결과는 치료기의 허가 및 성능의 동등성에 대한 명확한 기준을 포함하는 식약처의 가이드라인 개정 및 사용 중인 치료기의 음향 출력과 기술 문서와의 일치성 확인을 포함하는 치료기의 성능에 대한 규제 기관의 사후 관리의 필요성을 제기한다.

Purpose : The purpose of this study was to evaluate whether extracorporeal shock wave therapy (ESWT) is an effective treatment for myofascial pain syndrome (MPS) of upper trapezius. Methods : Study subject were 20 patients (7 male and 13 female). The patients were evaluated by assessing of pain and function using visual analog scale (VAS) and pressure pain threshold (PPT) and Constant-Murley scale (CMS). Statistical analysis was used paired T-test to know significance probability between pre-test and post-test. Results : There was no statistical significance in the change in PPT. But, VAS scores were significantly improved after ESWT (p<.05). Using the Constant-Murley score, this study showed a significant decrease in pain and a significant increase in range of motion of shoulder (p<.05). Conclusion : These results indicate that extracorporeal shock waves therapy could be considered as an effective and efficient treatment modality for myofascial pain syndrome of upper trapezius.

Objectives To determine the evidence of effectiveness and safety of extracorporeal shock wave therapy (ESWT) with meridian and acupoint theory for knee osteoarthritis. Methods By March 3, 2021, five foreign electronic databases and six Korean medical electronic databases were reviewed with the key words 'extracorporeal shock wave' and '(acupoint OR acupuncture point)'. This key words was set up to increase the sensitivity of the search. After the search, knee osteoarthritis study was selected based on the title and abstract and then included after full-texts were read. Results Five randomized controlled trials were eligible in our inclusion criteria. The meta-analysis of three studies showed positive results for the using ESWT with meridian and acupoint theory for knee osteoarthritis compared with the control group on efficancy rate, visual analog scale and lysholm knee score. but there remains a conundrum regarding the safety of ESWT in the treatment of knee osteoarthritis. Conclusions Most of studies showed ESWT with meridian and acupoint theory were statistically effective to knee osteoarthritis. However there are limitations that the number of selected studies was small, risk of bias was unclear. So use of ESWT with meridian and acupoint theory for knee arthritis has limited evidence compared to usual care.

Objectives This review was conducted to evaluate effectiveness and safety of extracorporeal shock wave therapy (ESWT) with meridian and acupoint theory for adhesive capsulitis. Methods By December 2021, 11 electronic databases were reviewed with the key words 'extracorporeal shock wave' and '(acupuncture OR acupoint OR meridian)'. This key words was set up to increase the sensitivity of the search. After the search, adhesive capsulitis study was selected based on the title and abstract and then included after full-texts were read. Results Five randomized controlled trials were eligible in our inclusion criteria. The meta-analysis of 3 studies showed positive results for the using ESWT with meridian and acupoint theory for adhesive capsulitis compared with the control group on efficancy rate and range of shoulder flexion. Conclusions Some studies showed ESWT with meridian and acupoint theory were statistically effective to adhesive capsulitis. But the evidence is limited due to the defective design of the included randomized controlled trials (RCTs). So use of ESWT with meridian and acupoint theory for adhesive capsulitis has limited evidence. More well-designed RCTs are required to provide clearer evidence for this claim.

Purpose: To evaluate the results of extracorporeal shock wave therapy (ESWT) for patients with chronic proximal plantar fascitis. Materials and Methods: Between April 2005 and April 2006, 35 cases (24 patients) who were followed more than 6 months were evaluated. By $EvoTron^{(R)}$, 2 sessions of ESWT (Group 1: 1200 and Group 2: 1500 shock waves / session of $0.12\;mJ/mm^2$) were performed at 2 weeks interval. The mean age was 40.0 (range, 15-59) years. 13 patients were male and 11 patients were female. Visual analogue scale (VAS) on daily activity and a 100-point scoring system including 70 points for pain and 30 points for function were used. The clinical outcomes were rated as follows: excellent, no pain on daily activity; good, less than 50% of previous VAS; fair, 50-75% of previous VAS; or poor, more than 75% of previous VAS. Excellent and good were graded as satisfactory results. We compare clinical results between groups and evaluate the relationships between clinical results and duration of symptom, fascial thickening and previous steroid injection were evaluated. Results: Overall satisfactory rate were 71.4%. There was no significant difference of clinical results between groups. And there were no significant difference between clinical results and duration of symtom, preoperative fascial thickening and previous steroid injection. Conclusions: ESWT for recalcitrant chronic proximal plantar fascitis is useful treatment method with high patient satisfaction and pain relief, but more long-term study must be needed.

압전식 충격파 쇄석기를 사용하여 대상물을 파쇄하는 과정에서 발생하는 음의 특성을 조사한 결과, 대상물이 파쇄됨에 따라 방사음이 더욱 저주파대로 이동한다는 실험적인 결과가 발표되었고(2), 이 결과를 입증하기 위하여 실제의 대상물이 파쇄되어가는 과정을 모델링하여 제작한 대상물을 사용한 실험에서도 동일한 결과가 관측되었다. 본 논문에서는 이와 같이 실험적으로 밝혀진 연구결과를 이론적으로 확인하고자 한다. 따라서, 유한요소법을 이용한 수치 시뮬레이션을 실험과 유사하게 모델링한 대상물에 실행하였고, 시뮬레이션에서 관측된 결과를 제시하여 실험적으로 관측된 결과가 이론적으로도 유효하다는 것을 입증하였다.

Plantar fasciitis is the most common cause of heel pain. The diagnosis of plantar fasciitis is primarily based on the presentation of symptoms and physical examination. Patients usually complain of heel pain at the medial calcaneal tubercle when taking their first step in the morning or when walking after resting. Diagnostic imaging is rarely required for the initial diagnosis of plantar fasciitis; however, it can be used for differential diagnosis. Conservative treatments, such as stretching, rest, ice massage, oral analgesics, foot orthotics, use of night splint, and corticosteroid injection, may be effective. The majority of patients report improvement with conservative treatments, and those who show no response from conservative treatments for a duration of six months or longer can consider extracorporeal shock wave therapy or surgery.

This is a case report about left leg radiating pain treated with complex traditional Korean medical intervention, while the case did not responded to prolotherapy and extracorporeal shock wave treatment for lumbar herniated intervertebral disc (HIVD). The patient was diagnosed with a piriformis problem after a physical examination and was treated with lumbar and piriformis muscle treatment. After 9 sessions of treatment for 33 days, Numeric Rating Scale (NRS) for pain has been decreased from 8 to 3. Further studies with more cases and longer observation period should be conducted to provide evidence for optimum acupuncture procedure considering its effectiveness, safety and patients' compliance altogether.
