Evaluating the effectiveness of online Continuing medical education during the COVID-19 pandemic.

OBJECTIVES: The study determined the effects of online continuing medical education (CME) on the clinical competency, performance, and patient outcomes of physicians and other healthcare professionals during the COVID-19 pandemic regarding the topics of COVID-19 and back pain. METHODS: Survey studies on six online CME activities were conducted from April 2020 to February 2021 at a South Korean hospital. Surveys were conducted immediately after and three months after the CME activity to measure the effectiveness of the CME activity regarding professional competence and performance, as well as patient outcomes. RESULTS: A total of 624 individuals participated in the six CME activities. Of the 2007 post-activity responses, a total of 1135 out of 1332 (85.21%) participants indicated that they were satisfied with the online education activities, and a total of 1752 out of 2007 (87.29%) participants responded that the content would influence their clinical practice. Upon a three-month follow-up, 477 out of 611 (78.07%) respondents indicated that they had made actual changes to their clinical practice. CONCLUSIONS: The online delivery method is effective for delivering CME. The results suggest that online CME ultimately influences physicians' clinical competency and performance, which leads to enforcing change in clinical practice.

Multicentre randomised controlled clinical trial of electroacupuncture with usual care for patients with non-acute pain after back surgery.

BACKGROUND: The purpose of this study was to investigate the effectiveness and safety between electroacupuncture (EA) combined with usual care (UC) and UC alone for pain reduction and functional improvement in patients with non-acute low back pain (LBP) after back surgery. METHODS: In this multicentre, randomised, assessor-blinded active-controlled trial, 108 participants were equally randomised to either the EA with UC or the UC alone. Participants in the EA with UC group received EA treatment and UC treatment twice a week for 4 weeks; those allocated to the UC group received only UC. The primary outcome was the VAS pain intensity score. The secondary outcomes were functional improvement (Oswestry Disability Index [ODI]) and the quality of life (EuroQol-5-dimension questionnaire [EQ-5D]). The outcomes were measured at Week 5. RESULTS: Significant reductions were observed in the VAS (mean difference [MD] -8.15; P=0.0311) and ODI scores (MD -3.98; P=0.0460) between two groups after 4 weeks of treatment. No meaningful differences were found in the EQ-5D scores and incidence of adverse events (AEs) between the groups. The reported AEs did not have a causal relationship with EA treatment. CONCLUSIONS: The results showed that EA with UC treatment was more effective than UC alone and relatively safe in patients with non-acute LBP after back surgery. EA with UC treatment may be considered as an effective, integrated, conservative treatment for patients with non-acute LBP after back surgery. CLINICAL TRIAL REGISTRATION: KCT0001939.

Association between alcohol consumption and osteoarthritis prevalence in Korea as assessed by the alcohol use disorders identification test (AUDIT): a cross-sectional study.

BACKGROUND: Osteoarthritis (OA) holds significance as a highly prevalent disorder in elderly populations. Various studies have been conducted on the association between alcohol consumption and OA, but the results have often been conflicting. The aim of this study was to investigate the relationship between alcohol consumption and OA in a large-scale sample representative of the Korean population. METHODS: Among the 25,534 participants surveyed in the fifth Korean National Health and Nutrition Examination Survey (2010-2012), 7165 individuals aged ≥50 who responded to drinking-related items were analyzed. The Alcohol Use Disorders Identification Test (AUDIT) grade was calculated, and radiologic examination analysis included the Kellgren-Lawrence (KL) grade of the lumbar spine, hip, and knee joints. Logistic regression analysis was performed to evaluate the association between AUDIT grades and OA through estimation of odds ratios (ORs). RESULTS: In crude analyses, OA (KL grade ≥ 2) of the lumbar spine and knee was more prevalent towards Zone I, but following adjustment, knee OA prevalence significantly increased in Zone III and IV compared to Zone I (Zone III: OR 1.464, 95% confidence interval (CI) 1.027-2.088; Zone IV: OR 1.543, 95% CI 1.028-2.317, respectively). Meanwhile, adjusted hip and lumbar OA values showed positive associations towards Zone IV, but did not reach statistical significance. Additional analyses of the association between alcohol consumption and pain severity of knee OA patients were nonsignificant. CONCLUSIONS: These results imply that radiological knee OA, rather than symptomatic knee OA, is associated with alcohol consumption.

Association between liver enzymes and bone mineral density in Koreans: a cross-sectional study.

BACKGROUND: Osteoporosis is a major health concern for both men and women, and associated fractures incur substantial economic burden. While there are a multitude of studies on bone mineral density (BMD) and liver diseases, not many studies have assessed the association between liver enzyme levels and BMD in homogeneous populations. METHODS: The current study investigated the association between serum liver enzyme levels and BMD at various sites in Koreans. Out of 21,517 surveyees of the 5th Korean National Health and Nutrition Examination Survey (2010-2012), 7160 participants' data on BMD, serum liver enzymes, and full covariate data were included for cross-sectional analysis. BMD at the femoral neck, lumbar spine, entire femur, and whole body was assessed using dual energy X-ray absorptiometry (DEXA), and liver enzymes included aspartate aminotransferase (AST), alanine aminotransferase (ALT), and gamma(γ)-glutamyl transferase (GGT) levels. Differences in participant characteristics by BMD and liver enzyme levels were analyzed, and complex sample design regression analysis adjusted for multiple covariates was performed to assess the relationship between liver enzymes and BMD. RESULTS: Negative associations were seen with GGT and BMD at all sites (P ≤ 0.02), ALT with lumbar spine (P = 0.0013), and AST with lumbar BMD (P = 0.0009). In particular, GGT presented strong negative associations with BMD in postmenopausal women and elder men. CONCLUSIONS: This study demonstrates a negative relationship between liver enzyme levels and BMD, and suggests that a significant association exists between osteoporosis/decreased BMD and liver disorders.

Characteristics and status of Korean medicine use in whiplash-associated disorder patients.

BACKGROUND: Patients are free to choose conventional or Korean medicine treatment under the dual medical system in Korea, and the prevalence of patients who choose Korean medicine treatment for whiplash-associated disorders (WADs) is high. This study analyzed the sociodemographic characteristics and medical service use in this population to provide healthcare providers with basic usage information of complementary and alternative medicine for WAD. METHODS: A total of 8291 outpatients who registered under automobile insurance coverage and visited the main branch of Jaseng Hospital of Korean Medicine from April 1, 2014 to August 10, 2016 were included. Data on sociodemographic characteristics, symptoms, and accident and treatment-related details were collected from electronic medical records. Univariate and multivariate regression analyses were performed to identify baseline factors predictive of total treatment duration. RESULTS: The most prevalent demographic of patients who chose Korean medicine for WAD treatment was males in their thirties whose initial visit to the hospital was 16.1 ± 94.1 days from the accident. Neck pain accompanied by low back pain (57.0%) was the most common complaint, and for singular pain, neck pain (13.5%) was the most prevalent. Baseline numeric rating scale (NRS) pain levels were generally moderate (4-6) regardless of area. Patients received 7.2 ± 10.2 sessions of treatment for 32.6 ± 55.3 days. The most commonly prescribed treatment modalities in order of highest frequency were acupuncture, cupping, pharmacopuncture, and herbal medicine, which collectively accounted for > 90% of treatments. Acupuncture was administered 29.0 ± 40.8 times, and cupping 14.0 ± 18.7 times as the two highest frequency treatments. In multivariate regression analysis, longer treatment periods were found to be associated with higher NRS, older age, and delayed initial visits at baseline. CONCLUSIONS: This study highlights the characteristics and Korean medicine use of WAD patients. These results are particularly relevant and informative for consideration of personal preferences and effective prioritization in further insurance coverage.

Anti-Osteoporotic Activity of Harpagoside by Upregulation of the BMP2 and Wnt Signaling Pathways in Osteoblasts and Suppression of Differentiation in Osteoclasts.

Harpagoside (1) is an iridoid glycoside isolated from the radix of Harpagophytum procumbens var. sublobatum, commonly called Devil's claw. The anti-osteoporotic effect of 1 was investigated in both in vitro cell cultures and in vivo using an ovariectomized (OVX) mouse model. Compound 1 induced bone formation by stimulating osteoblast proliferation, alkaline phosphatase activity, and mineralization in osteoblastic MC3T3-E1 cells. Treatment with 1 increased the mRNA and protein expression of bone formation biomarkers through regulation of the BMP2 and Wnt signaling pathway in MC3T3-E1 cells. Compound 1 also suppressed the RANKL-induced osteoclastogenesis of cultured mouse bone marrow cells. Oral administration of 1 restored the OVX-induced destruction of trabecular bone. The bone mineral density of the femur was also increased significantly by 1. The elevated serum levels of osteocalcin, C-terminal telopeptide, and tartrate-resistant acid phosphatase in the OVX mice were decreased by treatment with 1. These findings suggest that compound 1 may protect against bone loss induced by OVX in mice by regulating stimulation of osteoblast differentiation and inhibition of osteoclast resorption. Therefore, harpagoside (1) is a potential candidate for management of postmenopausal osteoporosis.

Analysis of medical service use of knee osteoarthritis and knee meniscal and ligament injuries in Korea: a cross-sectional study of national patient sample data.

BACKGROUND: Osteoarthritis (OA) and meniscal and ligament injuries of the knee are the two most common knee disorders in Korea. The aim of this study was to analyze the demographic characteristics, medical service use and related costs for these disorders, and the results are expected to help inform practitioners, researchers, and policy-makers. METHODS: The present study aimed to evaluate incidence and patient characteristics, and to assess current medical service use, usual care, and medical expenses of knee disorders by analyzing 2014 national patient sample data from the Korean Health Insurance Review and Assessment Service. Data was extracted using 3% stratified sampling from all Korea national health insurance claims submitted in 2014, and analyzed. Usual care for M17 knee osteoarthritis and S83 knee meniscal and ligament injury codes of the International Classification of Diseases, 10th revision (ICD-10) were determined by investigating total number of patients, sociodemographic characteristics, days in care, number of visits, and expenses. RESULTS: Knee OA showed the highest incidence in females aged ≥60 years, whereas meniscal and ligament injuries of the knee were most prevalent among patients aged <20 years and young adults. Total inpatient care expenses exceeded the cost of ambulatory care for both disorders. Ambulatory care was mainly provided at primary care clinics, with 90% of these visits made to orthopedic specialists. Medical expenses for knee OA and meniscal and ligament injuries were largely due to procedures/surgeries and injections, and procedures/surgeries and hospitalizations, respectively. Total replacement arthroplasty was the most commonly performed surgery for knee OA, while meniscectomy and cruciate ligament reconstruction were the most often performed surgeries for meniscal and ligament injuries. Intra-articular injection rates were 55% in knee OA patients and 3% in meniscal and ligament injury patients. Aceclofenac, diclofenac, and tramadol were the most frequently prescribed analgesics. CONCLUSIONS: The current findings may be used as basic data for establishing medical policies and can benefit researchers and clinicians in recognizing trends and patterns of treatment for knee disorders.

Delayed Spontaneous Resorption of Lumbar Intervertebral Disc Herniation: A Case Report.

Background • Large intervertebral disc herniation is often managed with surgery, but it is not uncommon for spontaneous resorption of herniated disc material to occur. Although the majority of spontaneous disc resorption occurs in the acute phase, an unusual case of delayed intervertebral disc regression at 18 mo postonset is presented. Case Presentation • A 32-y-old female patient presented with acute low-back pain and pain in both legs a Korean medicine hospital specializing in spinal disorders. Massive intervertebral disc herniation was found on lumbar magnetic resonance imaging (MRI), and inguinal and genital pain and numbness was suggestive of risk of cauda equina syndrome. Although she was recommended for surgery, the patient steadfastly refused surgical intervention and continued to receive nonsurgical Korean medicine treatment. Imaging studies including computed tomography scans and MRIs were taken in consideration of possible spontaneous disc regression at 3 and 6 mo, and 1 y after onset of symptoms with no initial disc resorption. However, delayed spontaneous regression of most of the herniated disc material was observed at 18 mo, and the majority of pain symptoms and functional disability recovered up to 2 y postonset. Conclusions • Delayed intervertebral disc resorption was observed in a case of large disc herniation well past the acute phase, and there was noticeable time difference in resolution on MRI and subsequent improvement in pain and functional recovery.

Quality of medical service, patient satisfaction and loyalty with a focus on interpersonal-based medical service encounters and treatment effectiveness: a cross-sectional multicenter study of complementary and alternative medicine (CAM) hospitals.

BACKGROUND: Treatment effectiveness holds considerable importance in the association between service quality and satisfaction in medical service studies. While complementary and alternative medicine (CAM) use grows more prominent, comprehensive evaluations of the quality of medical service at CAM-oriented hospitals are scarce. This study assesses the quality of medical services provided at a CAM-oriented hospital of Korean medicine using the service encounter system approach and analyzes the influence of treatment effectiveness on patient loyalty. METHODS: A survey study using one-on-one interviews was conducted using a cross-sectional design in outpatients visiting one of fifteen Korean medicine facilities located throughout Korea. A total of 880 surveys were completed from June to July, 2014, and 728 surveys were included in the final analysis after excluding incomplete or incorrect questionnaires. The reliability and validity of the surveys was confirmed using Cronbach's alpha coefficient and confirmatory factor analysis, and a structural equation modeling analysis was performed to verify causality and association between factors (quality of medical service, treatment effectiveness, patient satisfaction, and intent to revisit). RESULTS: The measured factors of physician performance and quality of service procedures had a positive effect on treatment effectiveness. The impression of the facilities and environment directly impacted satisfaction rates for interpersonal-based medical service encounters, while treatment effectiveness positively affected satisfaction regarding quality of medical service. However, treatment effectiveness had a more significant effect on satisfaction compared to facilities and environment, and it indirectly affected satisfaction and directly influenced intent to revisit. Treatment effectiveness and satisfaction both positively influenced intent to revisit. CONCLUSIONS: The importance of treatment effectiveness should be recognized when examining quality of medical services, and we hope that these findings may contribute to future studies.

Survey of integrative lumbar spinal stenosis treatment in Korean medicine doctors: preliminary data for clinical practice guidelines.

BACKGROUND: Considering that large variations exist amongst practitioners in lumbar disorder management and the significant costs that lumbar disorders incur, determining clinical practice patterns to provide preliminary data for standardization should be given higher priority. Lumbar spinal stenosis (LSS) is commonly treated using integrative non-surgical methods by Korean medicine doctors (KMDs) in Korea, and this is the first study to assess current Korean medicine practice trends for LSS. METHODS: A survey on KMD diagnosis, treatment, prognosis and decision-making in LSS treatment was developed in a 3-step procedure of preliminary drafting, revision based on extramural expert opinion, and final editing. The survey was conducted at the internal conference of a spine-specialty Korean medicine hospital on January 25th, 2015. RESULTS: The response rate was high at 79.19% (n = 118/149). Participants replied that they treated 7.3 ± 6.8 LSS patients/day using a multimodal treatment method consisting of acupuncture, pharmacopuncture, herbal medicine, Chuna manipulation, and electroacupuncture. Acupuncture mainly used Ashi points and MSAT, and pharmacopuncture mainly Shinbaro solution. The most frequently prescribed herbal medicine was Chungpa-jun, and the most commonly applied Chuna techniques were sidelying lumbar extension dysfunction correction technique, and prone lumbosacral joint distraction method. Radiological findings were mainly referred to for diagnosis, and clinical symptoms, age, radiological findings, and medical history were regarded to be important for prognosis. Participants replied that 7.8 ± 3.3 weeks were required for 50% reduction in pain, and 16.1 ± 7.7 weeks for 80% reduction. CONCLUSIONS: These results suggest that KMDs in Korea combine a conventional approach to LSS and a Korean medicine approach to low back pain for integration of empirical- and evidence-based diagnosis and treatment. The findings may contribute in bridging the divide between evidence and clinical practice guidelines for Korean medicine treatment of LSS and real-world clinical practice in future research.

Usage report of pharmacopuncture in musculoskeletal patients visiting Korean medicine hospitals and clinics in Korea.

BACKGROUND: Pharmacopuncture is a relatively new acupuncture therapy combining acupuncture with herbal medicine. While pharmacopuncture is applied extensively in Korean medicine treatment, there are no clinical reports regarding what types of pharmacopuncture are used for which diseases. METHODS: Data was extracted retrospectively from the electronic medical records of all inpatients and outpatients at 12 Korean medicine hospitals and clinics during the period of December 17, 2010 to October 2, 2014. Treatment patterns for acupuncture, electroacupuncture and pharmacopuncture were analyzed. Principle diagnosis codes, frequency of treatment, pharmacopuncture type and costs were investigated to assess pharmacopuncture use in clinical settings. RESULTS: During the study period, a total 33,415 inpatients and 373,755 outpatients visited the study sites, and most were musculoskeletal. Among inpatients and outpatients, 98.6 % and 77.6 % received pharmacopuncture, respectively. Administration rate of pharmacopuncture for the 10 most frequent principle diagnosis codes was 97.2-99.3 % in inpatients, and that for outpatients was 73.0-91.5 %. The average number of pharmacopuncture sessions in pharmacopuncture recipients was 8.2 ± 12.3 for outpatients and 25.8 ± 18.7 for inpatients. The mean total cost for pharmacopuncture per patient was $556.24 ± 174.62 among inpatients, and $149.16 ± 243.85 among outpatients. Estimated average cost per pharmacopuncture session was $23-24 for inpatients, and $17-18 for outpatients. Shinbaro1, bee venom, Hwangryunhaedok, and Shinbaro2 were the most frequently used pharmacopuncture types. CONCLUSIONS: This is the first analysis of treatment patterns of pharmacopuncture in a large-scale Korean medicine hospital/clinic patient population. We verified patterns of pharmacopuncture use for musculoskeletal disease treatment in Korea, and use of pharmacopuncture varied depending on disease or symptom severity. These results are expected to contribute to future clinical study design and standardization of pharmacopuncture.

Long term follow-up of cervical intervertebral disc herniation inpatients treated with integrated complementary and alternative medicine: a prospective case series observational study.

BACKGROUND: Symptomatic cervical intervertebral disc herniation (IDH) presenting as neck pain accompanied by arm pain is a common affliction whose prevalence continues to rise, and is a frequent reason for integrative inpatient care using complementary and alternative medicine (CAM) in Korea. However, studies on its long term effects are scarce. METHODS: A total 165 patients with cervical IDH admitted between January 2011 and September 2014 to a hospital that provides conventional and Korean medicine integrative treatment with CAM as the main modality were observed in a prospective observational study. Patients underwent CAM treatment administered by Korean medicine doctors (KMDs) in accordance with a predetermined protocol for the length of hospital stay, and additional conventional treatment by medical doctors (MDs) as referred by KMDs. Short term outcomes were assessed at discharge and long term follow-ups were conducted through phone interviews after discharge. Numeric rating scale (NRS) of neck and radiating arm pain, neck disability index (NDI), 5-point patient global impression of change (PGIC), and factors influencing long term satisfaction rates in PGIC were assessed. RESULTS: Of 165 patients who received inpatient treatment 20.8 ± 11.2 days, 117 completed the long term follow-up up at 625.36 ± 196.7 days post-admission. Difference in NRS between admission and discharge in the long term follow-up group (n = 117) was 2.71 (95% CI, 2.33, 3.09) for neck pain, 2.33 (95% CI, 1.9, 2.77) for arm pain, and that of NDI 14.6 (95% CI, 11.89, 17.32), and corresponding scores in the non-long term follow-up group (n = 48) were 2.83 (95% CI, 2.22, 3.45) for neck pain, 2.48 (95% CI, 1.84, 3.12) for arm pain, and that of NDI was 14.86 (95% CI, 10.41, 19.3). Difference in long term NRS of neck pain and arm pain from baseline was 3.15 (95% CI, 2.67, 3.64), and 2.64 (95% CI, 1.99, 3.29), respectively. PGIC was reported to be "satisfactory" or higher in 79.5% of patients at long term follow-up. CONCLUSIONS: Though the observational nature of this study limits us from drawing a more decisive conclusion, these results suggest that integrative treatment focused on CAM in cervical IDH inpatients may achieve favorable results in pain and functional improvement. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02257723. Registered October 2, 2014.

The association between mental health, chronic disease and sleep duration in Koreans: a cross-sectional study.

BACKGROUND: Sleep duration holds considerable importance as an indicator of mental/physical health. The objective of this study was to investigate the association between sleep duration, mental health, and chronic disease prevalence in Koreans. METHODS: Of 31,596 subjects eligible for the Korean National Health and Nutrition Examination Survey V (2010-2012), 17,638 participants who answered items on sleep duration (aged ≥ 19 yrs) were analyzed in a cross-sectional study. Association between sleep duration, mental health, and chronic disease prevalence was assessed using logistic regression, and adjusted for various socioeconomic and lifestyle characteristics. RESULTS: Short or long sleep duration showed correlations with mental health, and items of significance showed gender-specific patterns. Women displayed significant associations with stress and depressive symptoms, and men with stress, thoughts of suicide, and psychiatric counseling. While stress was related with short sleep duration in both genders, depressive symptoms showed a relationship with long duration in men, and short duration in women. Prevalence of any chronic disease was associated with ≤ 6 h sleep when adjusted for factors including mental health, and among chronic diseases, cancer and osteoarthritis showed associations with short sleep duration, while diabetes and dyslipidemia were associated with normal sleep duration. CONCLUSIONS: Mental health problems were associated with sleep duration with gender-specific patterns. Associations with osteoarthritis, cancer, diabetes, dyslipidemia and abnormal sleep duration persisted after adjustment for mental health.

Guillain-Barré syndrome mistaken for a common spinal disorder: a case report.

CONTEXT: Many patients with musculoskeletal issues seek traditional Korean medicine or complementary and alternative medicine (CAM) to treat or help deal with their health conditions. Practitioners and patients should be aware of diseases that can exhibit similar symptoms, consequently complicating diagnosis and treatment. OBJECTIVE: The study intended to examine a case of Guillain-Barré syndrome (GBS), in which the patient presented with back pain, leg pain, and weakness that gave cause for diagnostic error at onset. Design • The research team has reported a case study. SETTING: The study was conducted at Jaseng Hospital of Korean Medicine in Seoul, Korea. PARTICIPANT: After initially being prescribed back surgery for lumbar disc herniation, as confirmed by lumbar magnetic resonance imaging (MRI) at a previous hospital, a 54-y-old female with low back and leg pain as her chief complaint chose to transfer to a Korean medicine hospital for nonsurgical treatment. INTERVENTION: The patient became nonambulatory owing to a sudden decrease in muscle strength during admission and underwent a cervical MRI to assess for cervical myelopathy because she developed additional neck pain and upper-limb symptoms. She then was diagnosed with GBS and received a regime of symptomatic treatment with CAM, including acupuncture, electroacupuncture, pharmacopuncture, and herbal medicine. RESULTS: The cervical MRI results showed that the symptoms were not due to myelopathy or radiculopathy, and GBS was suspected because of the progressive ascending weakness, absence of myotatic reflexes in the lower limbs, and preceding flu-like symptoms. The patient showed swift recuperation after the CAM treatments, recovering motor strength and ambulation. CONCLUSIONS: A seemingly typical patient with musculoskeletal symptoms may turn out to have a completely different pathology, and clinicians should keep such potential confounders and comorbidities in mind when diagnosing patients.

A survey among Korea Medicine doctors (KMDs) in Korea on patterns of integrative Korean Medicine practice for lumbar intervertebral disc displacement: Preliminary research for clinical practice guidelines.

BACKGROUND: Patients seek Korean Medicine (KM) treatment for a broad range of complaints in Korea, but predominantly for musculoskeletal disorders. We investigated lumbar Intervertebral Disc Displacement (IDD) practice patterns of Korean Medicine doctors (KMDs) within a hospital/clinic network specializing in KM treatment of spinal disorders through survey of diagnosis and treatment methods. METHODS: Questionnaires on clinical practice patterns of KM treatment for lumbar IDD were distributed to 149 KMDs on January 25th, 2015. The questionnaire included items on sociodemographic characteristics, clinical practice patterns, and preferred method of lumbar IDD diagnosis and treatment. KMDs were asked to grade each treatment method for absolute and relative importance in treatment and prognosis, and safety. RESULTS: A total 79.19 % KMDs (n = 118/149) completed the survey, and results showed that integrative care mainly consisting of acupuncture, herbal medicine, Chuna manipulation, and pharmacopuncture was administered to IDD patients. The participant KMDs largely relied on radiological findings (MRI and X-ray) for diagnosis. 'Eight principle pattern identification', 'Qi and Blood syndrome differentiation' and 'Meridian system syndrome differentiation' theories were generally used for KM syndrome differentiation. The most frequently prescribed herbal medication was Chungpa-jun, and most commonly used Chuna technique was 'sidelying lumbar extension displacement treatment'. IDD patients received 1.9 ± 0.3 treatment sessions/week, and KMDs estimated that an average 9.6 ± 3.5 weeks were needed for 80 % pain relief. CONCLUSIONS: This is the first study to investigate expert opinion on KM treatment of IDD. Further randomized controlled trials and clinical guidelines based on clinical practice patterns of KM are called for.

Cross-cultural adaptation of the Korean Synkinesis Assessment Questionnaire: A validation study.

Objective: The Synkinesis Assessment Questionnaire (SAQ) is a reliable tool to assess synkinesis symptoms; however, it is yet to be validated in Korea. Thus, this study aimed to translate and validate the Korean SAQ. Methods: This validation study was set in a clinic in Seoul, Korea, that provides general integrative medicine services. A total of 100 participants with facial palsy were enrolled. Participants completed the SAQ, House-Brackmann grade (HB grade), Sunnybrook Facial Grading System (SB), and Facial Disability Index (FDI). The forward-backward translation method was followed. Of the 100 participants, 31 underwent a second assessment for test-retest reliability. Internal consistency and test-retest reliability were evaluated using Cronbach's alpha coefficient. The construct validity of the Korean version of the SAQ was tested using Spearman's rank correlation coefficient. Results: The internal consistency score for the SAQ was 0.789, and the test-retest reliability score was 0.787. According to Spearman's rank correlation coefficient, the SAQ correlations to the synkinesis subdomain of SB score, total SB score, HB grade, and physical function domain in the FDI score were 0.366 (p < .001), -0.386 (p < .001), 0.315 (p = .001), and -0.269 (p = .007), respectively. All values were statistically significant. Conclusions: The Korean SAQ is a valid and reliable tool used to evaluate synkinesis in patients with facial palsy. Level of Evidence: Level 3.

The process of National Health Insurance coverage for Chuna Manual Therapy in Korea: A qualitative study.

BACKGROUND: Chuna Manual Therapy (CMT) has been widely used in Korea, and coverage in Korean National Health Insurance (NHI) was finally implemented in 2019. The objectives of this study were to analyze the process of NHI coverage for CMT qualitatively, and to summarize important roles, streams, and implications regarding its inclusion in the modern public health insurance system. METHODS: Related literature was collected and 8 key personnel involved in the policy-making process were qualitatively interviewed, and Zahariadis' version of the Multiple Streams Framework (MSF) was applied to analyze the policy agenda setting and the roles of stakeholders. RESULTS: Through the collaborative efforts of various stakeholders, a pilot coverage project for CMT was implemented in 2017, and coverage was expanded nationwide in 2019. MSF showed that it was mainly achieved through three streams: governmental change (political stream), demand from the general public and KM doctors (problem stream), and strengthening/reinforcement of the feasibility and acceptability of the policy (policy steam). Also, the roles of policy entrepreneurs and resulting changes were shown to be significant for the overall process. CONCLUSION: NHI coverage for CMT was realized through collective policy and research efforts from the government and academic sectors. The roles of stakeholders were shown to be significant in the overall process, and documentation of their involvement is hoped to be of use of other countries that utilize traditional and/or manual medicine.

The substantial clinical benefit of comprehensively considering low back pain and radiating pain caused by lumbar intervertebral disc herniation.

BACKGROUND: Patients with lumbar disc herniation (LDH) may experience low back pain (LBP) and radiating pain (RP). Currently, there is no substantial clinical benefit (SCB) of assessing both LBP and RP due to LDH. OBJECTIVE: To determine enhanced SCB values by simultaneously assessing LBP and RP. METHODS: We retrospectively evaluated hospitalized LDH patients with concomitant LBP and RP between June 1, 2012, and May 31, 2013, and determined the numeric rating scale (NRS) and Oswestry Disability Index (ODI) scores at admission and discharge. Furthermore, the area under the receiver operating characteristic curve (AUC) was computed to assess diagnostic accuracy. RESULTS: SCB as per NRS for both LBP and RP was -2.50 in the 186 enrolled patients (AUC: 0.699 and 0.704, respectively). SCB as per ODI was -18.78 (AUC: 0.771). SCB for the mean of the two NRS scores for LBP and RP was -2.75 (AUC: 0.757). SCB for NRS score with a larger change in LBP and RP was -3.50 (AUC: 0.767). CONCLUSIONS: SCB may be determined by comprehensively considering LBP and RP and choosing the mean NRS or NRS score with a large change.
