This randomized sham-controlled trial suggests that acupuncture treatment shows better effect on the reduction of the bothersomeness and pain intensity than sham control in participants with cLBP.
IntroductionTemporomandibular disorders (TMDs) are common musculoskeletal conditions in the maxillofacial area. Although strong relationships between TMDs and other pain and diseases exist, few studies have comprehensively assessed the association between chronic diseases, ophthalmologic and otolaryngologic disorders and TMD.MethodsOf 25,534 individuals included in the fifth Korea National Health and Nutrition Examination Survey (2010–2012), 17,575 aged ≥20 years who completed survey items on TMD symptoms were included for cross-sectional analysis. Logistic regression analysis was performed to assess the association between chronic diseases, ophthalmologic and otolaryngologic disorders and examination findings, and TMD symptoms after adjusting for various confounding variables.ResultsOut of 17,575 participants, 2,059 (11.75%) reported experience of ≥1 TMD symptom(s). Compared to individuals without chronic disease, those with asthma (odds ratio (OR) 1.46; 95% confidence interval (CI) 1.09–1.96), migraine (1.44; 1.26–1.65), osteoarthritis (1.51; 1.20–1.89), thyroid dysfunction (1.49; 1.13–1.96), and depressive symptoms (1.51; 1.29–1.77) had higher ORs for TMD prevalence. Participants with tinnitus (1.97; 1.70–2.27), hearing difficulties (1.55; 1.29–1.87), dizziness (1.52; 1.27–1.82), rhinitis (1.46; 1.28–1.65), and xerophthalmia (1.82; 1.57–2.12) also displayed higher ORs for TMD prevalence. Patients diagnosed with chronic rhinosinusitis upon otolaryngologic examination exhibited an OR of 1.44 (95% CI 1.11–1.87) for TMD prevalence, while that for individuals with abnormal laryngoscopic results was 0.57 (95% CI 0.36–0.90).ConclusionsThese findings imply that TMDs, chronic diseases, and ophthalmologic and otolaryngologic disorders hold various correlations, suggesting the need for multitarget approaches to effectively address this phenomenon.
Background Anemia, which is a major public health problem worldwide, represents a decline in the oxygenation function, and can therefore be related to low strength. However, hemoglobin cannot repair muscles directly, but is beneficial only in a supportive role. Previous studies on the relationship between handgrip strength and anemia have been controversial. Thus, we aimed to analyze the association between handgrip strength and anemia in Korean adults. Methods This cross-sectional study used the 2013-2017 data from the 6th and 7 th Korean National Health and Nutrition Examination Survey (KNHANES) that included 16,638 Korean adults, aged �19 years, who met the inclusion or exclusion criteria. Differences in sociodemographic factors (sex, age, education, income, and employment), lifestyle factors (alcohol consumption, smoking, and physical activity), and illness and health factors [body mass index (BMI), vitamin intake, iron intake, comorbid illnesses, and handgrip strength] by existence of anemia, were analyzed using the Chi square test. Binary logistic regression analysis was used to measure the association between handgrip strength and anemia, while adjusting for other possible confounders. Subgroup analysis, stratified by sex and age, was performed. Results Among Korean adults aged �19 years, 745,296 (7.7%) had anemia. A higher odds ratio, adjusted for other covariates/factors (OR) of anemia occurred in the weak handgrip strength group than in the strong handgrip strength group (OR = 1.92, 95% CI: 1.58-2.33). The subgroup analysis showed a higher OR adjusted for other covariates/factors of anemia in the
Objective To review the literature and systematically evaluate the effectiveness of Chuna (or Tuina) manual therapy (C[T]MT) on pain and function for musculoskeletal disorders. Methods We searched 15 English, Chinese, Japanese, and Korean databases using relevant keywords. All randomized controlled trials (RCTs) of C(T)MT for musculoskeletal disorders were considered, and we limited analyses to studies with a low-risk bias for randomization and/or allocation concealment. Results Sixty-six RCTs with 6,170 participants were included. One sham-controlled RCT showed that C(T)MT relieved pain more effectively than a sham control (SMD −3.09 [−3.59, −2.59]). For active-controlled RCTs, pooled meta-analysis showed that C(T)MT had statistically significant effects on pain reduction, especially compared to traction (P < 0.00001), drugs (P = 0.04), and physical therapies (P < 0.0001). For functional improvement, combined effects of C(T)MT with drugs (P = 0.04) and traction (P = 0.05) also showed similar positive effects. Conclusions This systematic review suggests that C(T)MT is safe and effective for pain reduction and functional improvement for musculoskeletal diseases; however, the evidence for functional improvement was not as strong as for pain reduction. For future studies, high-quality RCTs such as sham-controlled studies with standardized interventions are needed to provide sufficient evidence on the effects of C(T)MT for musculoskeletal diseases.

IMPORTANCEThe incidence rate of neck pain is increasing worldwide, and the disease is associated with a high social burden. Manual therapy has been widely applied in the treatment of neck pain, but a high-quality, pragmatic randomized clinical trial for this treatment has not been conducted to date. OBJECTIVE This study aimed to compare the effectiveness of Chuna manual therapy with that of usual care for patients with chronic neck pain. DESIGN, SETTING, AND PARTICIPANTSA multicenter, assessor-blinded, pragmatic, randomized clinical trial was conducted between October 18, 2017, and June 28, 2019. This intention-to-treat analysis included 108 patients with chronic neck pain persisting for at least 3 months; patients were recruited from 5 hospitals in Korea. INTERVENTIONSTen sessions (2 sessions per week for 5 weeks) of Chuna manual therapy or usual care (electrotherapy and oral medication) were conducted. MAIN OUTCOMES AND MEASURES The main outcome was the difference in visual analog scale (VAS) score for chronic neck pain between baseline and 5 weeks after randomization. RESULTS This randomized clinical trial recruited 108 patients (mean [SD] age, 38.4 [9.3] years; 73 women [67.6%]). Fifty-four patients were allocated to the Chuna therapy group, and 54 received usual care. At 5 weeks after randomization, manual therapy showed statistically superior results compared with usual care in terms of pain (difference in chronic neck pain VAS, 16.8 mm; 95% CI, 10.1-23.5 mm), function (difference in Neck Disability Index, 8.6%; 95% CI, 4.2%-13.1%), and quality of life (difference in the European Quality of Life-5 Dimension 5 Levels (EQ-5D-5L) scores, −0.07 points; 95% CI, −0.11 to −0.02 points). Regarding the 1-year cumulative values measured using area under the curve analyses, superior outcomes were attained in the manual therapy group in terms of the numerical rating scale for chronic neck pain (1.3 points; 95% CI, 0.5-2.0 points), Neck Disability Index (6.7%; 95% CI, 2.5%-10.9%), Neck Pain Questionnaire (7.4%; 95% CI, 2.3%-12.6%), and EQ-5D-5L scores (−0.03 points; −0.07 to 0.00 points). CONCLUSIONS AND RELEVANCEIn this randomized clinical trial, for patients with chronic neck pain, Chuna manual therapy was more effective than usual care in terms of pain and functional recovery at 5 weeks and 1 year after randomization. These results support the need to consider recommending manual therapies as primary care treatments for chronic neck pain. (continued) Key Points Question Is Chuna manual therapy more effective than usual care (electrotherapy and medication) in week 5 after randomization for chronic neck pain? Findings This randomized clinical trial of 108 patients found that compared with usual care, Chuna manual therapy was more effective in terms of pain and functional improvements at week 5 and year 1 after randomization and in terms of cumulative 1-year results given the accelerated recovery of nonspecific chronic neck pain. Meaning These results support the need to consider the use of Chuna manual therapies, such ...
