Is laser acupuncture an effective complementary therapy for obesity management? A systematic review of clinical trials

Laser Acupuncture versus Liraglutide in Treatment of Obesity: A Multi-Institutional Retrospective Cohort Study

BACKGROUND

Obesity is a global concern, driving the search for alternative treatments beyond lifestyle changes and medications. Laser acupuncture (LA) shows promise in obesity management, yet few studies compare it with FDA-approved medications. This study aimed to assess and compare LA's impact with liraglutide on weight reduction in obese individuals.

METHODS

Data from the Chang Gung Research Database (CGRD) (2013-2018) were analyzed. Primary outcomes included changes in body weight and BMI within 180 days, with secondary outcomes measuring the proportion achieving 5%, 10%, and 15% weight loss. Adverse events were also assessed.

RESULTS

Of 745 subjects (173 LA users, 572 liraglutide users), LA users lost more weight by day 180 (5.82 ± 4.39 vs. 2.38 ± 5.75 kg; p < 0.001) and had a greater BMI reduction (-2.27 ± 1.73 vs. -0.93 ± 2.25 kg/m2; p < 0.001). More LA users achieved 5% and 10% weight loss compared to liraglutide users (64.2% vs. 22.7%, 26.6% vs. 4.2%; all p < 0.001). After balancing baseline differences, LA's benefits remained significant. No adverse events were reported with LA.

CONCLUSIONS

LA may offer superior weight reduction compared to liraglutide. Future studies should explore LA alone or in combination with liraglutide for obesity management.

Laser Diode - GaAlAs Acupuncture in the Treatment of Central Obesity: a Randomized Clinical Trial

Background

: Obesity is a global health challenge. Traditional approaches, including increased physical activity, dietary interventions, and medical therapy, often yield limited success, propelling some patients toward costly and invasive procedures like bariatric surgery. Laser acupuncture has been suggested as a complementary therapeutic approach to overcome this challenge. The present study investigated the effectiveness of laser acupuncture treatment in weight loss and abdominal subcutaneous fat reduction.

Methods

: A randomized, blinded, sham-controlled clinical trial was conducted, with 30 subjects each in the intervention and control groups. Patients in the intervention group underwent 12 sessions of laser acupuncture treatment within a month (three sessions/week), whereas those in the control group received sham laser treatment on identical acupoints. The patients were instructed not to alter their physical activity levels or dietary regimens. All parameters were evaluated before and after the treatment.

Results

: Significant reductions in weight, body mass index, and waist circumference were noted in both intervention and control groups. Further analysis revealed a more significant decrease in the laser acupuncture group. Abdominal sonography revealed a marked decrease in periumbilical fat thickness in the intervention group. Conversely, laboratory evaluations showed no significant difference between the two groups.

Conclusion

: Laser acupuncture is an effective method for weight loss in patients with periumbilical abdominal fat. The observed impact on subcutaneous fat suggests its potential as a non-invasive intervention for individuals seeking weight management alternatives. Further research is warranted to validate these findings and explore the underlying mechanisms of laser acupuncture in adipose tissue modulation.

Effects of laser acupuncture on anthropometric parameters and lipid profile in obese adolescents

The purpose was to compare the effects of diet and exercise and laser interference and maneuver on anthropometric parameters and blood effects of object agents. The study was a randomized controlled longitudinal study. It included 45 adolescents from both sexes who were divided randomly into two groups: one group was treated with low calorie diet and exercise as group A and group B was treated with low calorie diet, exercise, and laser acupuncture. All parameters and blood samples were done before and after the interventions. Group A showed a highly significant reduction post intervention in anthropometric parameters: triceps skin fold thickness (SFT), biceps SFT, subscapular SFT, suprailiac SFT, abdominal SFT, mid-upper arm circumference (MUAC), waist C, and hip C, except for waste/hip (W/H) ratio which showed no significant difference, p > 0.05 and some lipid profiles (cholesterol, LDL) with p < 0.001 Whereas, a significant decrease in TG was observed (p < 0.05). On the other hand, a significant increase in HDL was observed (p < 0.05). Group B (LCD + exercise + LA) showed a highly significant reduction post intervention in anthropometric parameters: triceps SFT, biceps SFT, subscapular SFT, suprailiac SFT, abdominal SFT, MUAC, waist C, and Hip C, except for W/H ratio which showed no significant difference, p > 0.05 and lipid profile: cholesterol, LDL, and TG with (p < 0.001), whereas a highly significant increase in HDL was observed (p < 0.001). The current study revealed a significant difference between group A and group B regarding the percentage of change, where the highest values were found in group B compared to group A, in anthropometric parameters (weight, BMI, subscapular SFT, MUAC, waist circumference) and some lipid profiles (LDL and HDL) with p < 0.05. Laser acupuncture was a safe, easy, and more effective tool with extra effect in management of obesity when added to diet and exercise on anthropometric parameters and lipid profile.

Acupuncture Therapies for Individuals with Overweight or Obesity: An Overview of Systematic Reviews

PURPOSE

An increasing number of people are affected by overweight or obesity, and the personal and social health burden is growing rapidly. Acupuncture is gaining popularity as an alternative treatment to manage weight. This research aims to update and synthesize the evidence of acupuncture therapies from systematic reviews for treating overweight and obesity.

METHODS

Nine databases were searched from their inception to March 2022. Overweight or obesity was classified using standard diagnostic criteria. Published systematic reviews that included randomized controlled trials and quasi-randomized studies were eligible. Quality was assessed via the AMSTAR-2 scale and risk of bias using the ROBIS tool.

RESULTS

Thirty-eight systematic reviews were identified. Acupuncture therapies and auricular acupoint stimulation showed benefits in terms of reducing body weight and body mass index. Catgut embedding therapy and abdominal acupuncture are currently not in widespread use with insufficient evidence. Acupuncture therapies appear to be safe. Most of the reviews were assessed as having high risk of bias and low confidence in the findings.

CONCLUSION

There is a need for larger and more methodologically sound randomized controlled trials to evaluate the effectiveness of acupuncture therapies for individuals who are affected by overweight or obesity.

Acupuncture and related techniques for obesity and cardiovascular risk factors: a systematic review and meta-regression analysis

OBJECTIVE

To assess how acupuncture and related techniques affect weight-related indicators and cardiovascular risk factors compared with non-acupuncture interventions in overweight and obese patients.

METHODS

We searched PubMed, Embase and CENTRAL up to 19 April 2018 and included relevant randomised controlled trials (RCTs). Weighted mean differences (WMDs) and 95% confidence intervals (CI) were pooled using the inverse variance method with random-effects model. Prespecified hypotheses were tested in meta-regression to investigate the source of heterogeneity. Statistical software packages used were RevMan 5.3.5 and Stata 14.0.

RESULTS

Thirty-three RCTs were included (n=2503 patients). Compared with non-acupuncture interventions, acupuncture produced a greater reduction in body weight (WMD -1.76 kg, 95% CI -2.22 to -1.30, I²=77%; moderate quality), body mass index (WMD -1.13 kg/m², 95% CI -1.38 to -0.88, I²=85%; low quality) and waist circumference (WMD -2.42 cm, 95% CI -3.22 to -1.62, I²=75%; moderate quality). Acupuncture plus lifestyle intervention resulted in a greater reduction in body weight than acupuncture alone (MD -1.94 kg, 95% CI -3.17 to -0.70). Acupuncture also led to a greater reduction in total cholesterol (WMD -12.87 mg/dL, 95% CI -22.17 to -3.57, I²=87%; very low quality) and low-density lipoprotein cholesterol (WMD -13.52 mg/dL, 95% CI -21.47 to -5.58, I²=74%; low quality). The differences were not statistically significant for blood glucose or blood pressure.

CONCLUSION

In the short term, acupuncture and related techniques may produce a small but statistically significant degree of weight loss based on moderate- to low-quality evidence, and improve serum lipid parameters based on low- to very-low-quality evidence. Their effects on blood glucose and blood pressure remain uncertain.

Electroacupuncture improves cognitive deficits and insulin resistance in an OLETF rat model of Al/D-gal induced aging model via the PI3K/Akt signaling pathway

To investigate the effect of electroacupuncture (EA) on cognitive function and insulin resistance (IR) in an Al/D-gal-induced aging model for Alzheimer's disease (AD) using Ostuka Long-Evans Tokushima Fatty (OLETF) rats. The Al/D-gal-OLETF rats for AD were randomly divided into the EA and non-EA groups. Cognitive function was assessed using the Morris water maze (MWM). The morphology of the hippocampal neurons was observed using hematoxylin & eosin (H&E) staining. Aβ and total Tau in the hippocampus and cerebrospinal fluid (CSF) were detected using western blotting (WB) and enzyme-linked immunosorbent assay (ELISA). Fasting blood glucose (FPG) was determined using the glucose oxidase method. Plasma fasting insulin (FINS), serum C-peptide (C-P), and CSF insulin were detected using ELISA. The expression of the genes and proteins in the PI3K signaling pathway was detected using quantitative real-time PCR and WB. After EA intervention, the hippocampal Aβ and total Tau protein levels, body weight, FPG, FINS, and C-P were significantly decreased. The MWM showed that the percentage of time in the target quadrant of the EA group was elevated in the probe test. The protein levels of p-IRS1, p-IRS2, IDE, and p-GSK3β were significantly increased, while p-PI3K-p85α and p-Akt were decreased. In conclusion, EA improves cognitive function and insulin resistance in rat models of AD. The PI3K/Akt signaling pathway is involved in those changes.

Early Detection and Management of Prader-Willi Syndrome in Egyptian Patients

Prader-Willi syndrome (PWS) is a distinct neurodevelopmental disorder associated with the deletion within the chromosomal 15q11-q13 region or uniparental disomy of chromosome 15. The etiologic heterogeneity of PWS makes it very difficult to establish uniform diagnostic methods which would result in the detection of most affected individuals. The objective was to report the clinical criteria and oro-dental features in PWS, to report the effect of diet and laser acupuncture on PWS and highlighted an easy effective method for early diagnosis of individuals with PWS. The study included seventeen cytogenetically proven individuals with Prader-Willi syndrome. These patients were subjected to meticulous history taking, clinical examination including oro-dental examination, bone densitometry and neuropsychiatric evaluation. They received laser acupuncture sessions in addition to nutrition intervention. All cases had characteristic facies, hypotonia and various psychosocial difficulties. Other criteria of PWS were present in different percentages. Karyotyping revealed deletion 15q11-q13 in 6 patients, and fluorescence in situ hybridization (FISH) revealed a microdeletion in 15q11-q13 in the other 11 patients. To our knowledge, partial ankyloglossia, median grooved tongue and hypodontia have not previously been reported in PWS patients. Laser acupuncture sessions and diet were effective in weight decline for PWS patients. Our study emphasizes the importance of early detection of PWS, laser sessions, diet restriction and oro-dental examination in the follow up of patients with Prader Willi syndrome.

Laser Acupuncture: A Concise Review

Background: Laser acupuncture (LA)-the use of nonthermal, low-intensity laser irradiation to stimulate acupuncture points-has become more common among acupuncture practitioners in recent years. LA is promoted as a safer pain-free alternative to traditional acupuncture, with minimal adverse effects and greater versatility. However, little is known about the mechanism of action of LA, laser characteristics, and effectiveness of LA therapy. Objective: This concise review of LA describes basic parameters and procedures, potential mechanisms of action, and the current evidence for its clinical efficacy. The article also highlights the need for more robust research on LA that can be translated into evidence-based clinical practices. Conclusions: LA has many features that make it an attractive option as a treatment modality, including minimal sensation; short duration of treatment; and minimal risks of infection, trauma, and bleeding complications. Future studies with high-quality methodologies, ample sample sizes, and consistent and reproducible laser parameters are critically needed to increase understanding and establish potential future clinical applications.
