Acupuncture Reduces Stroke Risk Discovery

Acupuncture decreases the risk of stroke for patients with a traumatic brain injury (TBI). Stimulation of acupoints has been proven to reduce stroke risk and post-stroke depression. An investigation of 29,636 patients with TBI reveals that patients receiving acupuncture have a “lower probability of stroke than those without acupuncture treatment during the follow-up period.” Patients from 2000-2008 were reviewed from the Taiwan National Health Insurance Research Database. Follow-ups continued through the end of 2010. The study “showed significantly decreased risk of new-onset stroke events for patients with TBI who received acupuncture treatment. The present study is the first to report that acupuncture treatment was associated with reduced stroke risk for patients with TBI.”

The researchers note that acupuncture provides other medical benefits to patients with TBI. They noted, “Our previous study found that patients with TBI who received acupuncture treatment had less emergency care and hospitalization in the first year after injury compared with control.” Another study cited in the research “proved that acupuncture improves cognition and perception of sleep or sleep quality.”

The researchers uncovered numerous studies demonstrating that acupuncture is effective “in improving stroke patients’ physical abilities.” They also found concrete evidence showing that acupuncture helps to lower blood pressure, reduce inflammation and improve the “lipid profile.” They note that this type of research helps to explain why acupuncture is effective in reducing the risk of stroke in TBI patients.

The study is important in that the sample size is large and that strict study designs were used. Additionally, the researchers sorted for socio-demographics and preexisting medical conditions to ensure accurate results. As a result, the researchers give a 95% rating of confidence to the study’s outcome.

The breakdown shows some interesting results. Overall, incidence rates for strokes in TBI patients decreased from 7.5 per 1,000 patients in the non-acupuncture group to 4.9 in the acupuncture group. Sorted by gender, females without acupuncture had an incidence of 6.5 per 1,000 but with acupuncture had an incidence of 4.6. For males, the incidence was 7.9 per 1,000 for non-acupuncture patients and 5.2 for acupuncture patients. For TBI patients from ages 20-44, the incidence was 2.1 for non-acupuncture patients and 1.2 for acupuncture patients. For ages 45-64, the incidence was 10.6 for non-acupuncture patients and 7.4 for acupuncture patients. For TBI patients 65 and older, the incidence was 28.4 per 1,000 for non-acupuncture patients and 18.0 for acupuncture patients.

In other recent related research, investigators discovered that combining acupuncture with conventional medications decreases post-stroke depression (PSD). Researchers examined 150 patients in a controlled single blind study. They concluded that acupuncture combined with medications synergistically improves patient outcomes by decreasing post-stroke syndrome, improving limb function and benefitting serum biochemistry. The study group receiving both acupuncture and medications had significantly better patient outcomes than the medication only and acupuncture only groups. This research supports the integration of acupuncture into conventional medical settings for patients who have suffered a stroke.

Research: Acupuncture Lowers Fatigue & Ups Endurance

Many of us struggle to maintain physical strength during the long cold winter months. Acupuncture in conjunction with exercise protects not only your heart, but builds endurance too! If you feel ready to be a healthier, stronger you, call Rachel to schedule your acupuncture sessions!
New research demonstrates that acupuncture prevents fatigue and enhances athletic endurance. Scientists measured the effects of three acupuncture points on the swimming task ability and liver mitochondrial function of laboratory rats in a highly controlled investigation. The results revealed that the normal control group and model group had significantly shorter swimming exhaustion times than the acupuncture group, which demonstrated objective improvements in athletic endurance. The acupuncture group also demonstrated improvements in liver mitochondrial-respiratory function with a significantly lower oxygen consumption rate than the normal control and model groups. The acupuncture group also demonstrated significant improvements in the liver mitochondrial respiratory control rate (RCR) and the ratio of phosphorus to oxygen (P/O).

 The researchers measured additional interesting findings. They compared acupuncture point prescriptions. Group 1 received electroacupuncture at CV4 (Guanyuan) and ST36 (Zusanli) plus manual acupuncture stimulation at GV20 (Baihui). Group 2 received electroacupuncture at CV3 (Zhongji) and SP9 (Yinlinquan) and manual acupuncture stimulation at Yintang (EX-HN3). Group 1 demonstrated significantly better scores than group 2 thereby demonstrating that the CV4, ST36, GV20 acupuncture point prescription has markedly greater anti-fatigue effects.

The investigators note that the treatment principle for the CV4, ST36, GV20 acupuncture point prescription is Shuanggu Yitong, “strengthening both the congenital foundation and the acquired constitution and regulating the yang-qi of the body.” The measurements were geared to quantify the anti-fatigue effects of the point prescription by measuring physical activity capabilities and liver functions in laboratory rats. The researchers concluded that, “Electroacupuncture of CV4 and ST36 plus manual acupuncture stimulation of GV20 can improve the anti-fatigue capability in aging rats with yang-deficiency, which may be related to its effects in reducing liver mitochondrial oxygen consumption and increasing liver mitochondrial RCR and ratio of P/O.”

Another study took a different tack to determine if acupuncture has beneficial effects on bodily strength and endurance. Researchers from the International Society for Autonomic Neuroscience discovered that acupuncture controls the heart rate and increases the strength of cardiac autonomic function. The research indicates that specific acupuncture points may help to prevent heart attacks (myocardial infarctions) and arrhythmias.

Researchers conducted a study of acupuncture points CV17 (Shanzhong) and CV16 (Zhongting). Needling acupoint CV17 decreased the heart rate and increased the power of the high-frequency component of the HRV (heart rate variability), an index of the body’s ability to maintain control of the heart beat rate and rhythm through vagus nerve activity. The researchers conclude that CV17 “causes the modulation of cardiac autonomic function.” CV16 did not change the HRV or demonstrate the same level of beneficial effects on the heart rate as CV17. CV17 is able to activate the autonomic nervous system to control the heart rate by increasing vagal activity. Depressed HRV after MI, a heart attack, reflects a decrease in vagal activity and leads to cardiac electrical instability. Since acupuncture at CV17 increases the cardiac vagal component of HRV, it is an important acupuncture point for patients recovering from MI.

Improved exercise tolerance

A study from the University of Heidelberg in Germany has shown that acupuncture can improve exercise tolerance for people with congestive heart failure. The abstract for "Acupuncture improves exercise tolerance of patients with heart failure: a placebo-controlled pilot study" is available online.
