An updated review of the efficacy of cupping therapy

Intracranial mycotic aneurysm rupture following cupping therapy

Background

Cupping therapy is an alternative treatment that uses a small glass cup to suck the skin with a needle and has been used to manage skin problems and pain. However, serious complications have been reported. Herein, we describe a case of intracranial mycotic aneurysm rupture after cupping therapy.

Case Description

A 25-year-old male patient presented with a headache and fever after cupping therapy for atopic dermatitis. He was diagnosed with infective endocarditis, and antibiotic therapy was initiated. After that, he suddenly lost consciousness, and head imaging revealed a cerebral hemorrhage due to a ruptured intracranial mycotic aneurysm. He underwent craniotomy, which was successful, and he was transferred to a rehabilitation center with a modified Rankin scale score of 2 at three months post-stroke.

Conclusion

This case serves as a reminder of life-threatening infectious complication risks after cupping therapy. A patient who has a compromised skin barrier may experience serious adverse effects, especially when cupping is performed without implementing suitable infection prevention measures.

The effectiveness of cupping therapy on low back pain: A systematic review and meta-analysis of randomized control trials

OBJECTIVES

This study aims to investigate the effectiveness of cupping therapy on low back pain (LBP).

METHODS

Medline, Embase, Scopus and WANFANG databases were searched for relevant cupping RCTs on low back pain articles up to 2023. A complementary search was manually made on 27 September for update screening. Full-text English and Chinese articles on all ethnic adults with LBP of cupping management were included in this study. Studies looking at acute low back pain only were excluded. Two independent reviewers screened and extracted data, with any disagreement resolved through consensus by a third reviewer. The methodological quality of the included studies was evaluated independently by two reviewers using an adapted tool. Change-from-baseline outcomes were treated as continuous variables and calculated according to the Cochrane Handbook. Data were extracted and pooled into the meta-analysis by Review Manager software (version 5.4, Nordic Cochrane Centre).

RESULTS

Eleven trials involving 921 participants were included. Five studies were assessed as being at low risk of bias, and six studies were of acceptable quality. High-quality evidence demonstrated cupping significantly improves pain at 2-8 weeks endpoint intervention (d=1.09, 95% CI: [0.35-1.83], p = 0.004). There was no continuous pain improvement observed at one month (d=0.11, 95% CI: [-1.02-1.23], p = 0.85) and 3-6 months (d=0.39, 95% CI: [-0.09-0.87], p = 0.11). Dry cupping did not improve pain (d=1.06, 95% CI: [-0.34, 2.45], p = 0.14) compared with wet cupping (d=1.5, 95% CI: [0.39-2.6], p = 0.008) at the endpoint intervention. There was no evidence indicating the association between pain reduction and different types of cupping (p = 0.2). Moderate- to low-quality evidence showed that cupping did not reduce chronic low back pain (d=0.74, 95% CI: [-0.67-2.15], p = 0.30) and non-specific chronic low back pain (d=0.27, 95% CI: [-1.69-2.24], p = 0.78) at the endpoint intervention. Cupping on acupoints showed a significant improvement in pain (d=1.29, 95% CI: [0.63-1.94], p < 0.01) compared with the lower back area (d=0.35, 95% CI: [-0.29-0.99], p = 0.29). A potential association between pain reduction and different cupping locations (p = 0.05) was found. Meta-analysis showed a significant effect on pain improvement compared to medication therapy (n = 8; d=1.8 [95% CI: 1.22 - 2.39], p < 0.001) and usual care (n = 5; d=1.07 [95% CI: 0.21- 1.93], p = 0.01). Two studies demonstrated that cupping significantly mediated sensory and emotional pain immediately, after 24 h, and 2 weeks post-intervention (d= 5.49, 95% CI [4.13-6.84], p < 0.001). Moderate evidence suggested that cupping improved disability at the 1-6 months follow-up (d=0.67, 95% CI: [0.06-1.28], p = 0.03). There was no immediate effect observed at the 2-8 weeks endpoint (d=0.40, 95% CI: [-0.51-1.30], p = 0.39). A high degree of heterogeneity was noted in the subgroup analysis (I2 >50%).

CONCLUSION

High- to moderate-quality evidence indicates that cupping significantly improves pain and disability. The effectiveness of cupping for LBP varies based on treatment durations, cupping types, treatment locations, and LBP classifications. Cupping demonstrated a superior and sustained effect on pain reduction compared with medication and usual care. The notable heterogeneity among studies raises concerns about the certainty of these findings. Further research should be designed with a standardized cupping manipulation that specifies treatment sessions, frequency, cupping types, and treatment locations. The actual therapeutic effects of cupping could be confirmed by using objective pain assessments. Studies with at least six- to twelve-month follow-ups are needed to investigate the long-term efficacy of cupping in managing LBP.

Cupping Therapy as a Potential Complimentary Treatment for Meniere's Disease: A Case Report

Meniere's disease is defined by the presence of three essential symptoms: episodic vertigo, tinnitus, and sensorineural hearing loss. The mainstay of its management constitutes lifestyle modification and medical and surgical therapies. Cupping therapy is an ancient treatment that is still widely used especially in the Middle East, Africa, and the United Kingdom. This study portraits the case of a 54-year-old patient suffering from long-standing Meniere's disease. The patient was treated with the routine treatment that was to no avail. It was decided that the patient undergoes cupping therapy. Over two years of monthly cupping therapy sessions, the patient reported a decrease in intensity and frequency of symptoms until its disappearance. Cupping therapy has shown a positive outcome on the patient. According to our search, there is a previous case report published in 2020 that shares multiple similarities with our case. Further studies on cupping therapy and its efficacy, mechanism of action, and complications on a larger scale are advised.

A Versatile Nanovaccine Enhancement Strategy Based on Suction-Inspired Physical Therapy

Vaccine technology is effective in preventing and treating diseases, including cancers and viruses. The efficiency of vaccines can be improved by increasing the dosage and frequency of injections, but it would bring an extra burden to people. Therefore, it is necessary to develop vaccine-boosting techniques with negligible side effects. Herein, we reported a cupping-inspired noninvasive suction therapy that could enhance the efficacy of cancer/SARS-CoV-2 nanovaccines. Negative pressure caused mechanical immunogenic cell death and released endogenous adjuvants. This created a subcutaneous niche that would recruit and activate antigen-presenting cells. Based on this universal central mechanism, suction therapy was successfully applied in a variety of nanovaccine models, which include prophylactic/therapeutic tumor nanovaccine, photothermal therapy induced in situ tumor nanovaccine, and SARS-CoV-2 nanovaccine. As a well-established physical therapy method, suction therapy may usher in an era of noninvasive and high-safety auxiliary strategies when combined with vaccines.

Role of wet-cupping therapy in physiological and mental pains in patients with migraine: A quasi-clinical trial

BACKGROUND

There is growing evidence of the potential benefits of wet-cupping therapy in reducing physiological pain severity in migraine; however, the role of this therapy on mental pain is unclear in this process. Therefore, this study aimed to examine the effectiveness of wet-cupping therapy on physiological and mental pains in patients with migraine. In this study, 72 migraine patients were treated with wet-cupping therapy and followed up after 1 month.

METHODS

The severity of physiological and mental pain was measured before therapy, 10 minutes and 1 month following therapy.

RESULTS

The study showed that patients in the wet-cupping therapy had a significantly lower mean value of physiological (0.42 vs 3.39; P < .001) and mental pain (1.60 vs 3.06; P < .001) compared to the patients in the control group, respectively. The mean value of the physiological was significantly decreased from 6.97 (baseline) to 0.73 (10 minutes) and 0.63 (1 month; P < .001) in the wet-cupping therapy patients, and the mean value of mental pain from 3.76 (baseline) to 0.71 (10 minutes) and 1.71 (1 month; P < .001). The mean values of physiological and mental pains were significantly reduced (from 7.80-3.39; P < .001) and (from 3.48-3.06; P = .0044), respectively. The level of physiological pain severity was significantly decreased with a decreasing level of mental pain severity at the posttest within the control (r = 0.5471; P = .0002) and the wet-cupping therapy (r = 0.3814; P .0412).

CONCLUSION

This study showed that the physiological pain was controlled by the mental pain in the wet-cupping therapy.

Wet cupping with rehabilitation training for upper-limb poststroke spasticity: A systematic review and meta-analysis of randomized controlled trials

Background

Upper-limb poststroke spasticity (PSS) negatively impacts on patients' quality of life. An increasing number of clinical trials have indicated that wet cupping with rehabilitation training is conductive to alleviate spastic muscle tone, thereby to improve upper-limb function. However, related evidence base is insufficient. This study systematically investigates the efficacy and safety of wet cupping with rehabilitation training on stroke patients with upper-limb spasticity.

Methods

Eight separate databases and two clinical trial registries were searched from their inception to December 6, 2022. Two reviewers extracted the data and assessed the quality of the literature, independently. The mean difference (MD) or risk ratio (RR) were used as measure of effect size in meta-analysis. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) was used for the certainty of evidence.

Results

Eight randomized controlled trials (RCTs) were quantified for meta-analysis. The results indicated that in comparison with the control group, wet cupping with rehabilitation training was more effective in reducing modified Ashworth scale score (MD = -0.60, 95% CI: -0.74, -0.46; P < 0.00001) and the integral electromyography value of biceps muscle (MD = -4.71, 95% CI: -6.74, -2.67; P < 0.00001), but improving effective rate (RR = 1.28, 95% CI: 1.15, 1.41; P < 0.00001), Fugl-Myer Assessment score (MD = 4.84, 95% CI: 3.05, 6.64; P < 0.00001) as well as Barthel Index score (MD = 6.38, 95% CI: 2.20, 10.57; P = 0.003). However, no significant difference was found regarding the integral electromyography value of triceps muscle between groups (MD = 1.72, 95% CI: -2.05, 5.48; P = 0.37).

Conclusion

Wet cupping with rehabilitation training should be included in a comprehensive therapeutic regimen for stroke patients with upper-limb spasticity. However, these results need to be further verified by more RCTs with rigorous design and large sample size.

Evaluating the efficacy of moving cupping for chronic low back pain using shear wave elastography: A parallel-arm, randomized controlled trial

BACKGROUND

Chronic low back pain (CLBP) is a common condition that affects millions of people worldwide. Moving cupping has gained popularity as a complementary therapy for managing CLBP owing to its noninvasive and cost-effective nature. However, the lack of objective measures to assess its therapeutic effect has been a considerable challenge in evaluating the effectiveness of moving cupping for CLBP management.

METHODS

We developed a randomized controlled trial (RCT) protocol for evaluating the effectiveness of a noninvasive treatment using moving cupping by assessing muscle relaxation with shear wave elastography (SWE). It involves the recruitment of 68 patients with CLBP and randomly assigns them to either the treatment or control group. The treatment group will receive moving cupping therapy for 2 weeks, while the control group will receive placebo treatment. It will utilize SWE to evaluate muscle relaxation at baseline, after 2 weeks of treatment, and 1 week after the end of treatment. Subjective reports of pain intensity and quality of life are also recorded at each time point.

DISCUSSION

The protocol developed here utilizes SWE to objectively measure muscle stiffness, and coupled with moving cupping therapy, may be effective in conveying relative comparisons before and after treatment. Moving cupping therapy is expected to promote muscle relaxation and pain relief in patients with CLBP. This study has the potential to contribute to the development of objective measures for evaluating the therapeutic effects of traditional therapies and to provide valuable insight into their efficacy.

Using near-infrared spectroscopy to investigate the effects of pressures and durations of cupping therapy on muscle blood volume and oxygenation

Cupping therapy has been widely used to manage musculoskeletal impairment. However, the effects of pressure and duration of cupping therapy on the hemodynamic activity of the muscle have not been investigated. A 2 × 2 repeated measures factorial design was used to examine the main effect and interaction of pressure (-225 and -300 mmHg) and duration (5 and 10 min) on biceps muscle blood flow using near-infrared spectroscopy in 18 participants. The results showed that a significant interaction is between pressure and duration on deoxy-hemoglobin (p = 0.045). A significant main effect of pressure is on oxyhemoglobin (p = 0.005) and a significant main effect of duration is on oxyhemoglobin (p = 0.005). Cupping therapy at -300 mmHg for 10 min results in a higher oxyhemoglobin (6.75 ± 2.08 μM) and deoxy-hemoglobin (1.71 ± 0.78 μM) compared to other three combinations. Our study provides first evidence that the pressure and duration factors of cupping therapy can significantly affect muscle blood volume and oxygenation.

The efficacy and safety of cupping as complementary and alternative therapy for metabolic syndrome: A systematic review and meta-analysis

INTRODUCTION

This systematic review and meta-analysis aimed to assess the efficacy and safety of cupping therapy in patients with metabolic syndrome (MetS).

METHODS

This systematic review focused on patients with MetS and included randomized controlled trials (RCTs) that compared the effects of cupping therapy with control groups. A total of 12 electronic databases were searched from inception until February 03, 2023. The main outcome after the meta-analysis was waist circumference; the others included anthropometric variables, blood pressure, lipid profile, fasting blood glucose level, and high-sensitivity C-reactive protein level. The incidence of adverse events and the follow-up courses were also evaluated. Risk of bias (ROB) was evaluated using ROB 2.0 from the Cochrane Handbook.

RESULTS

This systematic review included five studies involving 489 patients. Some risks of bias were also identified. The meta-analysis revealed a statistically significance in waist circumference (MD = -6.07, 95% CI: -8.44 to -3.71, P < .001, I2 = 61%, τ2 = 3.4), body weight (MD = -2.46, 95% CI: -4.25 to -0.68, P = .007, I2 = 0%, τ2 = 0) and body mass index (MD = -1.26, 95% CI: -2.11 to -0.40, P = .004, I2 = 0%, τ2 = 0) between the cupping therapy and control groups. However, there were no significant results in total fat percentage and blood pressure values. Regarding biochemical markers, cupping significantly lowered the concentration of low-density lipoprotein cholesterol (MD = -3.98, 95% CI: -6.99 to -0.96, P = .010, I2 = 0%, τ2 = 0) but had no significant effect on total cholesterol, triglyceride, high-density lipoprotein cholesterol, fasting blood glucose, and high-sensitivity C-reactive protein. 3 RCTs reported no adverse events.

CONCLUSIONS

Despite some ROB and low to substantial heterogeneity of the included studies, cupping therapy can be considered a safe and effective complementary intervention for reducing waist circumference, body weight, body mass index, and low-density lipoprotein cholesterol in patients with MetS. In the future, well-designed, high-quality, rigorous methodology, and long-term RCTs in this population are required to assess the efficacy and safety of cupping therapy.

Disseminated Staphylococcus aureus infection after scarification wet cupping therapy: a case report and literature review

BACKGROUND

Cupping therapy is a complementary and alternative medical therapy used especially in pain management. It is generally considered a safe procedure, but complications, including life-threatening infection, may still occur. Understanding these complications is essential to safe and evidence-based use of cupping in practice.

CASE PRESENTATION

Here we report a rare case of disseminated Staphylococcus aureus infection after cupping therapy. After wet cupping, a 33-year-old immunocompetent woman developed fever, myalgia, and a productive cough accompanied by acute liver and kidney injury, iliopsoas abscess, and gastrointestinal bleeding. The patient was treated successfully with cefmetazole plus levofloxacin after microbiological and antimicrobial sensitivity testing.

CONCLUSIONS

Though rarely reported, clinicians, practitioners of cupping therapy, and patients should be aware of the risk of infection after cupping therapy. High hygiene standards are recommended for cupping therapy, even in immunocompetent individuals.

Effectiveness of self-management of dry and wet cupping therapy for low back pain: A systematic review and meta-analysis

BACKGROUND

Low back pain (LBP) can significantly affect a person's quality of life. Cupping has been used to treat LBP. However, various cupping methods are typically included in evaluating the efficacy of cupping therapy. Therefore, the objectives of this study were to evaluate the evidence from the literature regarding the effects of dry and wet cupping therapy on LBP in adults. Dry and wet cupping therapy are analyzed categorically in this study.

METHODS

We searched for randomized clinical trials with cupping in LBP published between 2008 and 2022. In dry or wet cupping clinical studies, pain intensity was assessed using the Visual Analogue Scale and present pain intensity, and the quality of life intensity was measured using the Oswestry disability index.

RESULTS

The 656 studies were identified, of which 10 studies for 690 patients with LBP were included in the meta-analysis. There was a significant reduction in the pain intensity score with present pain intensity using wet cupping therapy (P < .01). In addition, both cupping therapy groups displayed significant Oswestry disability index score reduction compared to the control group (both P < .01). The patients with LBP have a substantial reduction by using wet cupping but have not shown a considerable decrease by using dry cupping (P = .19). In addition, only wet cupping therapy groups displayed a significantly improved quality of life compared to the control group. The study had a very high heterogeneity (I2 > 50%). It means there is no standardization in the treatment protocol in randomized clinical trials. In the meta-regression, there was statistically significant evidence that the number of treatment times and intercepts were related (P < .01).

CONCLUSION

The present meta-analysis shows that wet cupping therapy effectively reduces the pain intensity of LBP. Furthermore, both dry wet cupping therapy improved patients with LBP quality of life.

Effect of durations and pressures of cupping therapy on muscle stiffness of triceps

Cupping therapy has been used for the alleviation of muscle soreness in athletes. However, clinical studies of cupping therapy show conflicting results. Lack of standardized guidelines of the dose-response relationship of cupping therapy, such as appropriate cupping duration and negative pressure, limits the adoption of cupping therapy in clinical practice. The objectives of this study were to investigate the effect of various pressures and durations of cupping therapy on reducing muscle stiffness. The 2 × 2 factorial design with the repeated measures and counterbalanced design was used to test four cupping protocols, including two negative pressures at -225 and -300 mmHg and two durations at 5 and 10 min, in 12 healthy young people. B-mode and elastographic ultrasound was used to assess muscle stiffness of the triceps before and after cupping therapy. The region of interest of elastographic image was divided into the superficial and deep layers for assessing the effect of cupping therapy on stiffness of various depths of the triceps. Normalized stiffness was calculated as a ratio of pre-cupping stiffness divided by post-cupping stiffness of each participant. The two-way analysis of variance (ANOVA) was used to examine the main effects of the pressure and duration factors and the interaction effect between the pressure and duration factors. The results showed that there were no interactions between the pressure and duration factors (overall layer p = 0.149, superficial layer p = 0.632, and deep layer p = 0.491). The main effects of duration of the overall, superficial and deep layers were p = 0.538, p = 0.097 and p = 0.018, respectively. The results showed that 10-min cupping at -300 mmHg is more effective on reducing stiffness of the deep layer of the triceps compared to 5-min cupping (p = 0.031). This study provides the first evidence that the dose of cupping therapy could significantly affect changes of triceps stiffness and the deep layer of the muscle is more sensitive to cupping therapy compared to the superficial and overall layers.

Acupuncture or cupping plus standard care versus standard care in moderate to severe COVID-19 patients: an assessor-blinded, randomized, controlled trial

Background

: Non-pharmacological strategies that have been proposed by complementary medical systems, can be effective in management of COVID-19.

Methods

: This study was designed as a three-arm, assessor-blinded, randomized controlled trial. A total of 139 hospitalized COVID-19 patients were randomly assigned into three groups: (1) acupuncture (ACUG), (2) cupping (CUPG), and (3) control (CTRG). All participants received conventional treatment. The primary study endpoint included changes in respiratory signs including oxygen saturation (SpO₂) and respiratory rate (RR). The secondary endpoints were COVID-19-related hospitalization duration and serious adverse events such as intensive care unit (ICU) admission, intubation or death, all up to day 30. Also, improvements in cough, dyspnea, chest tightness, oxygen demand, anorexia, headache, weakness, sore throat, and myalgia were evaluated.

Results

: Forty-two patients in ACUG, 44 patients in CUPG, and 42 patients in CTRG completed the trial. After 3 days, SpO₂ and RR improved significantly in CUPG and ACUG compared with CTRG (effect size: 8.49 (6.4 to 10.57) and 8.51 (6.67 to 10.34), respectively: p<0.001). Compared with CTRG, patients in CUPG and ACUG recovered faster (mean difference: 6.58 (4.8 to 8.35) and 9.16 (7.16 to 11.15), respectively) and except for two patients in ACUG who were admitted to ICU, none of patients in ACUG or CUPG needed ICU or intubation (p<0.001 in comparison to CTRG). Amelioration of clinical COVID-19 related symptoms reached a high level of statistical significance in CUPG and ACUG in comparison with CTRG (p<0.01).

Conclusion

: Cupping and acupuncture are promising safe and effective therapies in management of COVID-19.

Comparative Effectiveness of East Asian Traditional Medicine for Childhood Simple Obesity: A Systematic Review and Network Meta-Analysis

Childhood obesity leads to various comorbidities and usually persists into adulthood, increasing socioeconomic burden. In the absence of a clearly effective treatment, East Asian traditional medicine (EATM) therapies have been widely used. We aimed to analyze the comparative effectiveness and safety of EATM techniques for children with simple obesity through network meta-analysis (NMA). Twelve databases were searched for randomized controlled trials (RCTs) evaluating the effect of EATMs on childhood simple obesity. Individual EATMs were ranked based on the surface under the cumulative ranking curve. The risk of bias in the individual studies and publication bias in the NMA were evaluated. Thirty-three RCTs were included. Acupuncture, chuna, chuna plus acupressure, cupping plus acupressure, herbal medicine (HM), and HM plus acupuncture significantly reduced BMI compared with lifestyle management. Based on the treatment ranking, cupping plus acupressure was optimal for BMI reduction compared with a non-medical management, followed by chuna and HM. The quality of evidence for individual findings was usually moderate to low, and no serious adverse events of EATM were reported. Cupping plus acupressure might have a large beneficial effect, and chuna or HM probably have a moderate beneficial effect on reducing BMI in children with simple obesity.

The Effect of Wet Cupping (Al-hijamah) and Limonene on Oxidative Stress and Biochemical Parameters in Diabetic Rats

Background: According to the international diabetes federation, 629 million adults will suffer from diabetes by 2045. Wet cupping therapy is a combination of bleeding and dry cupping and has been used in traditional medicine as a complementary therapy for diabetes. Limonene was shown to have both antioxidant and antidiabetic activity but its potential alongside other treatments has not been thoroughly explored. Objectives: Although wet-cupping therapy is widely used under different conditions, its potential in the treatment of diabetes is not well-examined. Methods: Male Wistar rats were then injected with alloxan and nicotinamide to induce diabetes. After cupping, the rats’ serum nitric oxide, creatinine, SGPT, SGOT, cholesterol, triglyceride, glucose, GPX, urea, and HDL levels were determined. The glutathione, catalase, glutathione peroxidase, malondialdehyde, and protein level of the serum, renal, and liver were then measured. Results: The results showed a significant differences in serum glucose levels among the diabetic rats receiving wet cupping and limonene, in serum glutathione levels in diabetic rats receiving limonene or limonene and wet cupping compared to the diabetic rats, in liver GSH levels in control rats receiving limonene and wet cupping, in the liver GPX activity in control rats receiving limonene, and in liver catalase activity in control rats receiving limonene and wet cupping compared to control group. There was no significant change in serum NO, protein, creatinine, SGPT, SGOT, cholesterol, triglyceride MDA, urea, catalase, HDL, renal GSH, MDA, catalase, liver protein, and MDA Level. Conclusions: The findings of the present study suggested that a combination of limonene and wet cupping therapy could be presented as an agent to lower elevated blood glucose levels in diabetic rats. Further clinical studies are required to confirm the findings.

Possible mechanism and Atorvastatin-based treatment in cupping therapy-related subdural hematoma: A case report and literature review

Subdural hematoma (SDH) is one of the most lethal types of traumatic brain injury. SDH caused by Intracranial Pressure Reduction (ICPR) is rare, and the mechanism remains unclear. Here, we report three cases of SDH that occurred after substandard cupping therapy and are conjected to be associated with ICPR. All of them had undergone cupping treatments. On the last cupping procedure, they experienced a severe headache after the cup placed on the occipital-neck junction (ONJ) was suddenly removed and were diagnosed with SDH the next day. In standard cupping therapy, the cups are not usually placed on the ONJ. We speculate that removing these cups on the soft tissue over the cisterna magna repeatedly created localized negative pressure, caused temporary but repeated ICPR, and eventually led to SDH development. The Monro-Kellie Doctrine can explain the mechanism behind this - it states that the intracranial pressure is regulated by a fixed system, with any change in one component causing a compensatory change in the other. The repeated ICPR promoted brain displacement, tearing of the bridging veins, and development of SDH. The literature was reviewed to illustrate the common etiologies and therapies of secondary ICPR-associated SDH. Despite the popularity of cupping therapy, its side effects are rarely mentioned. This case is reported to remind professional technicians to fully assess a patient's condition before cupping therapy and ensure that the cups are not placed at the ONJ.

Warm Cupping of the Posterior Thorax in Combination with Standard Conventional Therapy for ARDS in COVID-19 Patients in ICU: a Case Series

Acute respiratory distress syndrome (ARDS) is commonly found in critically ill patients with coronavirus disease 2019 (COVID-19). As a non-pharmacological treatment of complementary and alternative medicine (CAM), cupping has been clinically used for respiratory symptoms. We sequentially identified a series of patients with COVID-19 with ARDS who were admitted to the intensive care unit (ICU). Warm cupping of the posterior thorax was performed for seven days. We collected longitudinal severity scores on cough, breathlessness, chest tightness, type of oxygen therapy, and oxygen saturation (SpO₂). We hereby report the changes in the severity scores in a series of eight patients who received 21 sessions of cupping in addition to conventional treatments. All patients reported improvement in symptom scores that was matched by an increase in SpO₂ by as much as 3.16%. All patients were discharged and did not require the use of a mechanical ventilator. The results suggest that combining cupping with conventional treatment may provide a good prognosis for patients with COVID-19 with ARDS.

Novel suction-based in vivo cutaneous DNA transfection platform

This work reports a suction-based cutaneous delivery method for in vivo DNA transfection. Following intradermal Mantoux injection of plasmid DNA in a rat model, a moderate negative pressure is applied to the injection site, a technique similar to Chinese báguàn and Middle Eastern hijama cupping therapies. Strong GFP expression was demonstrated with pEGFP-N1 plasmids where fluorescence was observed as early as 1 hour after dosing. Modeling indicates a strong correlation between focal strain/stress and expression patterns. The absence of visible and/or histological tissue injury contrasts with current in vivo transfection systems such as electroporation. Specific utility was demonstrated with a synthetic SARS-CoV-2 DNA vaccine, which generated host humoral immune response in rats with notable antibody production. This method enables an easy-to-use, cost-effective, and highly scalable platform for both laboratorial transfection needs and clinical applications for nucleic acid–based therapeutics and vaccines.

Effects of cupping therapy for obesity: A protocol for systematic review and meta-analysis

BACKGROUND

Obesity is a prevalent disease in modern society. Despite the various interventions available in conventional medicine, their success rates are not satisfactory because of the complex mechanisms involved in obesity. Cupping therapy is a traditional Chinese medicinal intervention, and it has become widely used in various clinical settings for the treatment of obesity. This systematic review and meta-analysis will investigate the effects of cupping on obesity.

METHODS

Three Korean databases (KoreaMed, Oriental Medicine Advanced Searching Integrated System, and ScienceON), 1 Japanese database (Citation Information by the National Institute of Informatics), 1 Chinese database (Chinese National Knowledge Infrastructure), MEDLINE/PubMed, EMBASE, and The Cochrane Central Register of Controlled Trials will be searched for studies published until March 2021. The primary outcome is body weight. The secondary outcomes will be body mass index, waist-hip ratio, waist circumference, hip circumference, body fat mass, body fat percentage, and adverse events.

RESULTS

This systematic review and meta-analysis will evaluate the effects of cupping therapy for obesity.

CONCLUSION

The results of this systematic review and meta-analysis will then be discussed in a related journal for clinicians working with obese patients to apply the interventions in this article.

Acute Effects of Dermal Suction on Passive Muscle and Joint Stiffness

The aim of the present study was to examine the acute effects of dermal suction on the passive mechanical properties of specific muscles and joints. Dermal suction was applied to the calves of 24 subjects. Passive plantar flexion torque was measured with the right knee fully extended and the right ankle positioned at 20°, 10°, 0°, and −10° angles, where 0° represents the ankle neutral position, and positive values correspond to the plantar flexion angle. The shear wave velocity (SWV) (m/s) of the medial gastrocnemius was measured in the same position using ultrasound shear wave elastography. The relationship between the joint angle and passive torque at each 10° angle was defined as passive joint stiffness (Nm/°). Passive muscle and joint stiffness were measured immediately before and after the dermal suction protocol. When the ankle joint was positioned at 20° (r = 0.53, P = 0.006), 10° (r = 0.43, P = 0.030), and −10° (r = 0.60, P = 0.001), the SWV was significantly higher after dermal suction than that before dermal suction. Regarding joint stiffness, we found no significant difference between the pre- and post-dermal suction values (partial η² = 0.093, P > 0.05). These findings suggest that dermal suction increases passive muscle stiffness and has a limited impact on passive joint stiffness.

Prioritizing Chinese medicine clinical research questions in cancer palliative care from patient and caregiver perspectives

BACKGROUND

Chinese medicine (CM) modalities, including acupuncture and Chinese herbal medicine (CHM), are popular palliative interventions among patients with cancer, but further clinical research is required to assess their effectiveness and safety.

OBJECTIVE

To prioritize top ten important CM clinical research questions from patients with cancer, cancer survivors and caregivers' perspectives via a face-to-face prioritization workshop in Hong Kong.

METHODS

A list of 25 CM clinical research questions for cancer palliative care, which were identified from existing systematic reviews (SRs) and overview of SRs, was presented to 17 participants (patients with cancer [n = 5], cancer survivors [n = 6] and caregivers [n = 6]). The participants were then invited to establish consensus on prioritizing top ten research questions.

RESULTS

Among the top ten priorities, five (50%) focused on acupuncture and related therapies, while five (50%) were on CHM. The three most important research priorities were (i) manual acupuncture plus opioids for relieving pain; (ii) CHM for improving quality of life among patients receiving chemotherapy; and (iii) concurrent use of CHM plus loperamide for reducing stomatitis.

CONCLUSION

The top ten participant-endorsed CM clinical research priorities for cancer palliative care can guide local researchers on future direction. They can also inform local research funders on patient-centred allocation of limited funding. Under limited research funding, the most important co-prioritized research question from professional and patient perspectives may be addressed first.

PATIENT OR PUBLIC CONTRIBUTION

Patients with cancer, cancer survivors and caregivers participated in conduct of the study to prioritize CM clinical research questions.

The efficacy and safety of cupping therapy for treating of intractable peripheral facial paralysis: A protocol for systematic review and meta-analysis

BACKGROUND

Peripheral facial paralysis (PFP) is a common clinical neurological disease and the incidence of intractable peripheral facial paralysis is on the rise. Symptoms include crooked mouth and eyes, tearing and shallow nasolabial folds. The disease seriously affects the physical and mental health of patients. At present, a large number of clinical studies have shown that cupping is effective in treating intractable peripheral facial paralysis (IPFP). Therefore, the purpose of this review is to evaluate the effectiveness and safety of cupping in the treatment of refractory peripheral facial paralysis.

METHODS

We will conduct a comprehensive and systematic search of relevant documents in the following databases: Medline, PubMed, the Cochrane Central Register of Controlled Trials (CENTRAL), Embase, Chinese Biomedical Literatures Database, China National Knowledge Infrastructure (CNKI), Wang Fang Database, Chinese Scientific Journal Database from inception to February 2021 without any language restriction. The 2 reviewers will be independently completed select research, extract data, evaluate research quality and use the Cochrane risk of bias tool to assess methodological quality. Using revman5.4 software for statistical analysis. The degree of heterogeneity will be Determined through heterogeneity test, to definite whether to adopt a random effects model or a fixed-effects model.

RESULTS

The protocol for the meta-analysis will systematically evaluate the efficacy and safety of cupping therapy for intractable peripheral facial paralysis patients.

CONCLUSION

This study will explore whether or not cupping therapy can be used as one of the non-drug therapies to prevent or treat intractable peripheral facial paralysis.

Evidence Map of Cupping Therapy

This study aimed to describe and assess the current evidence in systematic reviews on cupping therapy for various conditions. We searched PubMed, EMBASE, Cochrane Database of Systematic Reviews, China National Knowledge Infrastructure, and six Korean databases for systematic reviews of trials on cupping treatments for any condition published prior to March 2021. We used a bubble plot to graphically display the clinical topics, the number of articles, the number of participants in the total population, confidence, and effectiveness. Thirteen systematic reviews that met the inclusion criteria were included in the evidence map, and 16 bubbles were created. The findings from six reviews showed potential benefits of cupping for conditions such as low back pain, ankylosing spondylitis, knee osteoarthritis, neck pain, herpes zoster, migraine, plaque psoriasis, and chronic urticaria. Cupping has been applied in a variety of clinical areas, and systematic reviews in a few of these areas have demonstrated statistically significant benefits. The evidence map provides a visual overview of cupping research volume and findings. Evidence mapping can facilitate the transfer of knowledge from researchers to policymakers and promote research on musculoskeletal pain (such as low back pain, neck pain, and knee osteoarthritis) and skin disease (plaque psoriasis).

Effectiveness of Wet Cupping on Patients with Facial Acne Vulgaris: A 12-Week, Randomized, Single-Blind, Intervention-Sham-Controlled Trial

INTRODUCTION

Acne vulgaris is a widespread skin disorder. The aim of this study was to assess the effectiveness of wet cupping in the treatment of moderate to severe facial acne vulgaris.

METHODS

Between August 2018 and January 2020, eligible patients with moderate to severe facial acne were recruited in this single-blind, intervention-sham-controlled clinical trial in Iran. The intervention group received wet cupping twice and likewise the control group received sham cupping. Also, both groups received 500 mg azithromycin 3 times/week for 12 weeks. Acne grades were assessed 6 weeks and 12 weeks after beginning of the treatment by the dermatologist uninformed of group allocation and participant self-assessment. Quality of life was assessed with valid questionnaire before and after the treatment.

RESULT

Totally, 103 patients completed the trial. The patients in the intervention group had better improvement and grade of acne compared to the control group at the end of the trial. Patients showed a shorter time to removing facial lesions in the intervention group in contrast with the control group (p < 0.001). Quality of life significantly increased in the intervention group compared with the control group (p = 0.004).

CONCLUSION

Wet cupping plus antibiotic therapy seems to be more effective than antibiotic therapy per se in patients with facial acne vulgaris.

Effectiveness of wet cupping therapy on relieving pain in patients with chronic migraine: an observational study

BACKGROUND

Chronic migraine is a disabling condition that negatively affects many aspects of migraineurs' lives. Patients who use pharmacological agents experience various side effects. Some studies have reported clinical improvement following wet cupping therapy in migraine patients. This study examined the effectiveness of wet cupping therapy on headache severity and its complications in patients with migraine.

METHODS

In this study, a total of 29 patients previously diagnosed with migraine were treated with wet cupping therapy and followed up for headache severity. The severity of pain was measured before therapy, 1 h after therapy, and one month after therapy. The wet cupping therapy was performed by an experienced nurse who was not part of the research team.

RESULTS

The mean age of the patients was 36.17 (Sta. Deviation: 10.74 years; range: 22-68 years), and on average, patients had experienced migraine for 11.14 years. The severity of headache pain was decreased significantly from 6.66 (very intense pain) before cupping therapy to 2.48 (discomforting pain) 1 h after cupping therapy and 0.72 (very mild pain) one month after cupping therapy (p<0.001). The observed complications were skin pigmentation (6.9%), skin scarring (24.1%), and itching in the cupping region (31.0%).

CONCLUSIONS

The present study suggests a significant improvement in the severity of headache in migraine patients 1 h and one month after wet cupping therapy.

Cupping Therapy for Migraine: A PRISMA-Compliant Systematic Review and Meta-Analysis of Randomized Controlled Trials

BACKGROUND

Migraine is a common reason for primary headache disorders. Cupping is a frequently used traditional intervention for controlling pain including migraine. There have been no systematic reviews on the clinical effects of cupping on migraine.

OBJECTIVE

This systematic review and meta-analysis aimed to evaluate the effectiveness of cupping therapy for migraine. The search strategy was built for the presence of related keywords, such as "migraine" and "cupping therapy", in the title and abstract of research articles indexed in the MEDLINE, EMBASE, CENTRAL, and other databases. The randomized controlled trials (RCTs) of cupping therapy for migraine were searched and selected from inception to May 2019. We searched eight databases including PubMed, EMBASE, Cochrane Central Register of Controlled Trials. The selection process and the quality assessment were performed by 2 authors independently. The meta-analysis was conducted and qualitative analysis was also performed.

RESULTS

218 studies were identified, and 6 RCTs were enrolled in this review. In comparison to drugs, wet cupping showed a higher total effective rate (TER). In the dry cupping plus acupuncture, the result of TER showed more effectiveness (RR 1.05, 95% CI 0.99 to 1.12, P=0.13) compared with acupuncture alone, but there was no statistically significant difference. In qualitative analysis, the results showed wet cupping plus drugs treatment could quickly relieve pain and significantly improve patients' quality of life and wet cupping could reduce headache pain.

CONCLUSION

Cupping therapy could be effective for the treatment of migraine. However, the qualities of the evidence were low, so well-designed RCTs are needed to confirm the effectiveness of cupping. Systematic review registration: PROSPERO registration number is CRD42017054979.

Understanding Traditional Chinese Medicine Therapeutics: An Overview of the Basics and Clinical Applications

Traditional Chinese medicine (TCM) is a systematic healthcare system developed from clinical experience based on a scientific model of regulation. TCM relies on unique theories and practices to treat diseases and enhance health. These practices include Chinese herbal medicine and dietetics, acupuncture and moxibustion, and other non-medication therapies such as Chinese bodywork or manual therapy, known as "Tuina", and traditional biofeedback exercises, known as "Qigong" and "Taijiquan". The integration of TCM in Western health systems and research requires a rational communicable theory, scientific proof of efficacy and safety, and quality control measures. Understanding the structural concepts of the TCM language makes possible the parallelism to Western physiology, and the inherent rational use of the reflex therapeutic systems, anti-inflammatory mechanisms and mental training involved, for example, in acupuncture and "Qigong". The results of TCM clinical trials and fundamental research on its nature and mechanisms have encouraged the development and application of well-designed research strategies such as double blinding in acupucture to overcome limitations and resistances in integrating these practices into the existing biomedical paradigms of the West. This review aims to overview some TCM theoretical concepts and the evidence-based clinical application of TCM's leading practices to create an easy-to-consult and condensed source of information, available for the healthcare community, facilitating the understanding and communication between conventional health professionals and TCM practitioners and acupuncturists.

Influence of quantified dry cupping on soft tissue compliance in athletes with myofascial pain syndrome

PURPOSE

This study aimed to develop a quantitative dry cupping system that can monitor negative pressure attenuation and soft tissue pull-up during cupping to quantify soft tissue compliance.

METHODS

Baseball players with myofascial pain syndrome were recruited to validate the benefits of cupping therapy. Nine of 40 baseball players on the same team were diagnosed with trapezius myofascial pain syndrome; another nine players from the same team were recruited as controls. All participants received cupping with a negative pressure of 400 mmHg for 15 minutes each time, twice a week, for 4 weeks. Subjective perception was investigated using upper extremity function questionnaires, and soft tissue compliance was quantified objectively by the system.

RESULTS

During the 15-minute cupping procedure, pressure attenuation in the normal group was significantly greater than that in the myofascial group (p = 0.017). The soft tissue compliance in the normal group was significantly higher than that in the myofascial group (p = 0.050). Moreover, a 4-week cupping intervention resulted in an obvious increase in soft tissue lift in the myofascial pain group (p = 0.027), although there was no statistical difference in the improvement of soft tissue compliance. Shoulder (p = 0.023) and upper extremity function (p = 0.008) were significantly improved in both groups, but there was no significant difference between the two groups.

CONCLUSION

This quantitative cupping monitoring system could immediately assess tissue compliance and facilitate the improvement of soft tissues after cupping therapy. Hence, it can be used in athletes to improve their functional recovery and maintain soft tissues health during the off-season period.

Moving cupping therapy for plaque psoriasis: A PRISMA-compliant study of 16 randomized controlled trials

BACKGROUND

Clinical treatment of plaque psoriasis typically involves a comprehensive therapy, which is expensive and unsatisfactory, and some medications have serious side effects. Moving cupping therapy has shown good clinical efficacy in the treatment of plaque psoriasis; it can significantly relieve skin inflammation and excessive thickening of plaque psoriasis and has fewer side effects. However, a comprehensive evaluation of the current clinical evidence regarding its use is lacking.

METHODS

Several databases were systematically searched from inception to March 2, 2020, including PubMed, Embase, Cochrane Central Register of Controlled Trials, China Network Knowledge Infrastructure, and Wan Fang. This review included randomized controlled trials on plaque psoriasis treatment with the use of moving cupping and in combination with Chinese herbs or conventional Western medicine therapy. These trial findings were compared with the treatment results using placebo, pharmaceutical medications, or Chinese herbs. Moving cupping treatment frequency was also compared.

RESULTS

Sixteen trials with 1164 participants met the inclusion criteria. Meta-analysis showed that the intervention group (moving cupping therapy) had a significant effect compared with the no-moving cupping therapy group (weighted mean difference = -1.22, 95% confidence interval [CI] [-1.58, -0.85], P < .00001 random model; I = 85%). Furthermore, moving cupping (weighted mean difference = -1.19, 95% CI [-1.98, -0.39], P = .003 random model; I = 85%) or combined with pharmaceutical medications (weighted mean difference = -1.55, 95% CI [-1.89, -1.20], P < .00001 random model; I = 0%) were better than pharmaceutical medications alone in treating plaque psoriasis. Cupping therapy significantly improved psoriasis recurrence rate (risk ratio = 0.33, 95% CI [0.16, 0.68], P = .003 fixed model; I = 28%). However, for the visual analogue score, moving cupping showed no obvious advantages (weighted mean difference = -0.27, 95% CI [-0.71, 0.17], P = .22 random model; I = 64%). Moreover, studies reported that moving cupping reduced serum tumor necrosis factor-α and vascular endothelial growth factor levels more significantly than pharmaceutical medications. Moving cupping was associated with few transient adverse reactions, such as redness, itching, and local skin burning.

CONCLUSION

Moving cupping therapy could be an effective treatment either alone or as a combination therapy for plaque psoriasis. However, further large-scale, rigorously designed trials are needed to confirm these findings.

Combination Acupuncture and Cupping for Treating Adult Idiopathic Scoliosis

Background: There is limited previous English-language literature on acupuncture's ability to treat idiopathic scoliosis. This report shows the potential effectiveness of a combination of acupuncture and cupping therapies to treat curvature progression and thoracic back pain in adult idiopathic scoliosis. Intervention: A 34-year-old male veteran of the U.S. Armed Forces with thoracic back pain and muscle spasms originally presented to the chiropractic clinic at the Fargo Veterans Affairs Healthcare System, Fargo, ND. Per radiographs taken prior to the consultation, the chiropractor determined that the patient had an idiopathic right-convex scoliosis curve of ∼21°. Due to immobility of the thoracic spinal vertebra upon adjustment, he was referred to acupuncture care. After a clinical review, the acupuncturist hypothesized that a combination of utilizing acupuncture and cupping techniques would help relax the muscles along the thoracic spine, allowing correction of the patient's abnormal spinal curvature. Combination Traditional Chinese Medicine (TCM), using acupuncture with cupping therapy was given ∼2 times per week for several weeks, resulting in a total of 15 treatments. Results: After 15 treatments, this patient's subjective pain decreased by 85%. Anecdotally, he reported "feeling a bit looser." He continued to receive acupuncture and cupping treatments when his schedule allowed. Conclusions: The combination therapy was effective for treating musculoskeletal pain but was inconclusive with respect to its ability to treat adult idiopathic scoliosis. More research is needed on the efficacy of TCM for treating adult idiopathic scoliosis.

ACUTE OUTCOMES OF MYOFASCIAL DECOMPRESSION (CUPPING THERAPY) COMPARED TO SELF-MYOFASCIAL RELEASE ON HAMSTRING PATHOLOGY AFTER A SINGLE TREATMENT

BACKGROUND

Myofascial decompression (MFD), or cupping, and self-myofascial release (SMR) are common techniques utilized to treat soft tissue injuries and increase flexibility. MFD is a negative pressure soft tissue treatment technique using suction to manipulate the skin and underlying soft tissues. One method of SMR is a foam roller, where a patient rolls his/her bodyweight over a dense foam cylinder in a self-massaging fashion to mobilize soft tissues for the body part treated.

HYPOTHESIS/PURPOSE

The purpose of this investigation was to examine the acute effects on hamstring flexibility and patient-rated outcome measures comparing two soft tissue treatments, 1) MFD, and 2) a moist heat pack with SMR using a foam roller in patients with diagnosed hamstring pathology.

STUDY DESIGN

Pilot randomized controlled trial study.

METHODS

Seventeen collegiate athletes [13 males (20.6+/- years; 184.9+/-cm; 90.8+/-kg) and 4 females (20.5+/-years; 167.1+/-cm; 62.7+/-kg)] with diagnosed hamstring pathology (mild strain and/or symptoms of tightness, pain, decreased strength, and decreased flexibility) were randomly assigned to receive MFD or SMR. The MFD group (n = 9) received three minutes of static treatment using six plastic-valve suction cups along the hamstrings followed by 20 repetitions of active movement with cups in place. SMR (n = 8) received 10 minutes of heat treatment over the hamstrings followed by 60 seconds of general mobilization over the entire hamstring area, and 90 seconds of targeted foam rolling on the area of most perceived tightness. Passive hamstring flexibility (ROM) and a patient-rated outcome measure [Perceived Functional Ability Questionnaire (PFAQ)] were assessed before and immediately after treatment. The Global Rating of Change measure (GROC) was administered post-intervention.

RESULTS

Passive ROM and subjective PFAQ measures for overall flexibility and flexibility of the hamstrings were significantly different from pre- to post-intervention measurements regardless of the treatment received. A significant difference was found in favor of the MFD group for the GROC values.

CONCLUSION

The findings suggest that both treatments are beneficial in increasing hamstring length. Patients though felt an enhanced treatment effect using MFD over SMR for perceived benefits to hamstring flexibility.

LEVELS OF EVIDENCE

Level 2.

Cognitive and Emotional Aspects of Cupping Therapy

Cupping therapy has recently gained public attention and is widely used in many regions. Some patients are resistant to being treated with cupping therapy, as visually unpleasant marks on the skin may elicit negative reactions. This study aimed to identify the cognitive and emotional components of cupping therapy. Twenty-five healthy volunteers were presented with emotionally evocative visual stimuli representing fear, disgust, happiness, neutral emotion, and cupping, along with control images. Participants evaluated the valence and arousal level of each stimulus. Before the experiment, they completed the Fear of Pain Questionnaire-III. In two-dimensional affective space, emotional arousal increases as hedonic valence ratings become increasingly pleasant or unpleasant. Cupping therapy images were more unpleasant and more arousing than the control images. Cluster analysis showed that the response to cupping therapy images had emotional characteristics similar to those for fear images. Individuals with a greater fear of pain rated cupping therapy images as more unpleasant and more arousing. Psychophysical analysis showed that individuals experienced unpleasant and aroused emotional states in response to the cupping therapy images. Our findings suggest that cupping therapy might be associated with unpleasant-defensive motivation and motivational activation. Determining the emotional components of cupping therapy would help clinicians and researchers to understand the intrinsic effects of cupping therapy.

Cupping Therapy Does Not Influence Healthy Adult's Hamstring Range of Motion Compared to Control or Sham Conditions

Cupping therapy, a form of traditional Chinese medicine, has recently gained popularity as a therapeutic modality among sports medicine clinicians. While the use of cupping therapy to decrease musculoskeletal pain is supported by recent research findings, evaluations on the use of cupping therapy to influence range of motion (ROM) are limited. The purpose of the study was to identify if cupping therapy applied passively for 10 minutes increases flexibility compared to sham treatment or control conditions. Twenty-five participants with hamstring ROM less than 80° and no previous cupping therapy experience completed the study. Participants reported to the laboratory on three occasions for one of three randomly assigned treatment conditions (cupping, sham, or control) for 10 minutes while prone. Hamstring flexibility was evaluated three times (pre-treatment, post-treatment, and 10-minutes post-treatment) via ROM measured during an active straight leg raise. Participants returned on two other occasions to receive the remaining treatment conditions. A 3 (treatment condition) × 3 (time) repeated measures analysis of variance was utilized for statistical analysis. There was no interaction between condition and time (p = 0.78). Within-subjects effects for time (p = 0.76) was not significant. Post hoc pairwise comparison of treatment conditions found no differences between control and cupping (p = 0.36), cupping and sham (p = 0.35), or control and sham (p=0.98) conditions. Cupping therapy applied statically for 10 minutes does not increase hamstring flexibility compared to a sham treatment or control condition.

Standards for reporting interventions in clinical trials of cupping (STRICTOC): extending the CONSORT statement

BACKGROUND

The standards for reporting interventions in clinical trials of cupping (STRICTOC), in the form of a checklist and explanations for users, were designed to improve reporting of cupping trials, particularly the interventions, and thereby facilitating their interpretation and replication.

METHODS

A group of clinical experts, methodologists, epidemiologists, and editors has developed this STRICTOC checklist through a comprehensive process, including registration of this guideline, literature review, solicitation of comments, consensus meeting, revision, and finalization.

RESULTS

The STRICTOC checklist includes 6 items and 16 sub-items, namely cupping rationale, details of cupping, treatment regimen, other components of treatment, treatment provider background, and control or comparator interventions. Illustrative examples of each item are also provided.

CONCLUSIONS

It is intended that the STRICTOC, in conjunction with both the main Consolidated Standards of Reporting Trials (CONSORT) Statement and extension for nonpharmacologic treatment, will raise the reporting quality of clinical trials of cupping.Trial registration We have registered this study on the Enhancing the Quality and Transparency of Health Research (EQUATOR) Network: http://www.equator-network.org/library/reporting-guidelines-under-development/reporting-guidelines-under-development-for-clinical-trials/#STRICTOC.

Tissue Stiffness is Not Related to Pain Experience: An Individually Controlled Study in Patients with Chronic Neck and Back Pain

Background

Massage therapies such as cupping are often applied in patients with chronic neck and back pain with the assumption that they can reduce increased tissue stiffness and, therefore, improve pain. The aim of this study was to clarify whether tissue stiffness is related to pain experience in patients with chronic (>3 months) back and neck pain and whether it can be altered by a cupping massage.

Methods

The tissue stiffness of the point of subjectively felt maximum pain intensity of 40 patients with neck (n = 20) or lower back pain (n = 20) was measured by a myometer. Exact contralateral side served as an individual control. Side of higher stiffness was then treated with a cupping massage. 5, 10, 15, and 20 minutes as well as 24 hours after treatment, tissue stiffness was measured again. Patients rated their pain on a standardized pain questionnaire (neck pain disability score (NDI) or Oswestry disability index (ODI), respectively) before and 24 hours after treatment.

Results

Compared to the contralateral control side, the more painful side did not exhibit an increased stiffness of myofascial tissue before treatment (p=0.827). The tissue stiffness and the side difference between treated and nontreated control sides decreased significantly after cupping (p=0.002 and p=0.001, respectively) but returned to baseline after 24 hours. NDI and ODI scores significantly decreased 24 hours after cupping (NDI: p=0.012, ODI: p=0.002).

Conclusion

Tissue stiffness might not be related to pain experience in patients with chronic neck and lower back pain. Trial registration: German Clinical Trial Register (DRKS00011281).

Development of Evidence-Based Chinese Medicine Clinical Service Recommendations for Cancer Palliative Care Using Delphi Approach Based on the Evidence to Decision Framework

Objectives: Existing evidence supports the use of certain Chinese medicine (CM) interventions for symptom management among palliative cancer patients. However, evidence-based service recommendations tailored to the local context are needed for CM planning and implementation. In response, we aimed to establish consensus on CM clinical service recommendations for cancer palliative care among Hong Kong experts. Methods: Seven CM interventions showing statistically significant favorable results in existing systematic reviews (SRs) and overviews of SRs were subjected to a GRADE-ADOLOPMENT-based 2-round Delphi survey. Twelve Hong Kong experts in cancer palliative care, including conventionally trained physicians, CM practitioners, and nurses (n = 4 from each category), were invited to participate. Use of the Evidence to Decision framework within the GRADE-ADOLOPMENT approach enabled experts to consider aspects of problem priority, benefits, harms, equity, acceptability, and feasibility when making CM recommendations in cancer palliative care. Results: Three evidence-based CM interventions reached positive consensus as service recommendations, namely: (1) acupuncture for reducing fatigue among palliative cancer patients; (2) acupressure for reducing fatigue among palliative cancer patients; and (3) moxibustion for reducing nausea and vomiting among patients receiving chemotherapy. Median rating of recommendation ranged from 2.5 to 3.0 (interquartile range = 0.00-1.00) on a 4-point Likert-type scale, and the percentage agreement ranged from 83.4% to 91.7%. Conclusions: The GRADE-ADOLOPMENT approach facilitates a consensus-based process of reaching 3 evidence-based CM recommendations for cancer palliative care. Future studies may develop tailored strategies to implement these recommendations in the Hong Kong health system.

Dry Cupping, Ischemic Compression, or Their Combination for the Treatment of Trigger Points: A Pilot Randomized Trial

Background: Chronic neck pain (NP) attributed to myofascial pain syndrome is one of the particularly common skeletal muscle disorder associated with the hyperirritable zone in the taut band of muscle. Trigger points (TPs) are the physical interpretation of the myofascial pain syndrome. In the United States, 30%–85% of pain patients have been affected by myofascial TPs.

Objectives: To reveal preliminary evidence on the clinical efficacy of ischemic compression therapy, dry cupping, and their combination on improving the TPs' pressure pain threshold (PPT), neck range of motion (NROM), and neck disability index (NDI) in patients with TPs and nonspecific NP. Besides, assess the feasibility of conducting a randomized clinical trial (RCT).

Design: A randomized pilot study was conducted on 24 patients with TPs and nonspecific NP. Patients were randomly assigned to three groups: the cupping group, the ischemic compression group, and the combination therapy group. PPT, NROM, and NDI were assessed before and after 4 weeks of treatment.

Results: The results showed a statistically significant improvement in NDI, PPT, and NROM compared with values before the treatment (p < 0.05) in all groups. Although no significant difference was detected between ischemic compression (IC) and dry cupping, the combination approach showed significantly higher and faster improvement (p < 0.05).

Conclusions: It is feasible to conduct a main RCT. Both IC and dry cupping may hold promise in treating TPs; a combination of the two therapies may provide superior improving rate.

Synergistic effects of vacuum therapy and laser therapy on physical rehabilitation

[Purpose] This study aims to evaluate the synergistic effects of laser therapy and vacuum therapy in the rehabilitation of some disorders of the osteomuscular articular system (shoulder bursitis, low back pain, hip dysfunction after long-term impact of femoral endoprosthesis). [Participants and Methods] Three case reports were described. A vacuum laser system was used, which is a device that contains 1 handpiece with 3 red lasers (660 nm) and 3 infrared lasers (808 nm). This device contains 6 laser beams that are arranged around the vacuum chamber bore which generate negative pressure. Two weekly sessions were held, totalling 10 treatment sessions. Active goniometry was performed to assess range of motion (ROM) of the shoulder, lumbar spine and hip, and visual analogue scale (VAS) was used to evaluate pain in the pre and posttreatment period. [Results] There was a pain reduction and an increase in ROM in the different clinical cases. [Conclusion] Potentiating laser therapy through suctioning during the rehabilitation process leads to pain relief and increased functionality.

Suction Decompression of the Carpal Tunnel

Carpal tunnel syndrome (CTS) is a common nerve compression syndrome that includes symptoms of numbness and tingling in the median nerve distribution. Medical cupping therapy has been used for managing a variety of medical conditions, but, to the author's knowledge, the cupping device has not been directly applied over the carpal tunnel as a form of treatment. This case report involves a 27-year-old woman who presented with symptoms of CTS in the right hand and palpatory restriction over the right carpal canal. Electrodiagnostic testing confirmed mild CTS, and neuromuscular ultrasonography revealed a mildly enlarged median nerve at the wrist, which was also consistent with CTS. The patient was taught to use a cupping device that would allow her to apply suction over the ventral wrist daily. The patient noted improvement over several weeks and was asymptomatic at her 3-month follow-up visit. Repeated testing revealed that initial abnormalities in the wrist had resolved. Suction decompression of the carpal tunnel may be a viable alternative treatment for patients with mild CTS.
