Deqi makes no difference to osteoarthritis pain relief
Categories: Acupuncture research
Research carried out by UK scientists suggests that the intensity of de qi has no effect on the pain relief obtained from acupuncture by patients with osteoarthritis (OA).
Acupuncture affects men and women differently
Categories: Acupuncture research
Two new studies suggest that acupuncture may have different effects on men and women.
Needling LIV-3 affects systemic haemodynamics
Categories: Acupuncture research
A team from Japan has investigated the changes of blood flow in the radial and brachial arteries during acupuncture needling. Eighteen healthy volunteers received manual acupuncture bilaterally at Taichong LIV-3. Blood flow volume decreased significantly during acupuncture in both radial and brachial arteries, but was found to be increased at 180 seconds after acupuncture compared with baseline. S ...
Doctors become acupuncture patients rather than acupuncturists
Categories: Acupuncture research
A Norwegian study has investigated changes in the personal and professional use of acupuncture among physicians in Norway between 1994 and 2004. The results showed that the percentage of physicians having used acupuncture for their own complaints had more than doubled (18% in 2004 vs 8% in 1994), while the percentage that intended to use acupuncture for their own complaints remained steady (55% in ...
Reduced electrical impedance of acupuncture meridians associated with subcutaneous collagen bands
Categories: Acupuncture research
A new paper by American authors suggests that the reduced electrical impedances measured at acupuncture meridians are significantly associated with subcutaneous collagenous bands.Previous research has suggested that acupuncture meridians are physiologically characterised by low electrical impedance and anatomically associated with connective tissue planes. The new study assessed the electrical imp ...
Acupuncture analgesia mediated through adenosine
Categories: Acupuncture research
The understanding of how acupuncture's analgesic effects are mediated has been significantly improved, thanks to a paper from American authors. The team has, for the first time, identified the molecule adenosine as being potentially responsible for some of the effects of acupuncture in the body. Adenosine, which is known for its anti-inflammatory properties, its role in regulating sleep and its ef ...
Acupuncture trials get even STRICTA
Categories: Acupuncture research
A new version of the STRICTA (Standards for Reporting Interventions in Clinical Trials of Acupuncture) checklist has been published, setting out revised and expanded reporting guidelines for clinical trials of acupuncture. The new STRICTA checklist includes six items and 17 sub-items, which set out guidelines for the reporting of acupuncture rationale, details of needling, treatment regimen, other ...
Acupuncture increases muscle strength
Categories: Miscellaneous disorders, Acupuncture research
A single acupuncture treatment can increase isometric quadriceps strength, according to German authors. Thirty-three recreational athletes were randomised to receive acupuncture, sham acupuncture (needling at non-acupuncture points) and placebo laser acupuncture (deactivated laser device) in a double-blind crossover fashion, with one week between trials. The difference from baseline of the mean ch ...
Acupuncturists' behaviour affects pain
Categories: Knee, Acupuncture research
The way acupuncturists interact with patients has significant effects on pain reduction. In an American randomised controlled trial, acupuncturists were trained to interact in one of two communication styles that conveyed either 'high' or 'neutral' expectations of treatment outcomes. 455 patients with knee osteoarthritis were assigned to one of three groups over six weeks: waiting list, 'high', or ...
Pre-treatment expectations don't predict outcomes for back pain
Categories: Back, Acupuncture research
The relationship between patients' expectations of acupuncture and their outcomes may be more complex than previously believed. When US investigators analysed data from a randomised trial of acupuncture for chronic back pain, they found that pre-treatment expectations and preferences for acupuncture were not predictive of treatment outcomes. 477 acupuncture-naïve participants with chronic low bac ...
Unilateral acupuncture anaesthesia measurable bilaterally
Categories: Acupuncture research
Acupuncture induces objectively measurable anaesthesia on both the treated and untreated sides of the body. In a German study, twenty-four healthy volunteers received three different forms of acupuncture - manual acupuncture, low-frequency electroacupuncture, and high-frequency electroacupuncture - in a single-blinded crossover design. All forms of acupuncture were applied unilaterally at Sanyinji ...
Expectancy enhances acupuncture's immune benefits
Categories: Immunity, Acupuncture research
Not only does acupuncture enhance immunity, telling subjects that it does so increases the benefit. Sixty healthy volunteers were randomised to receive acupuncture at Quchi L.I.-11 (groups one and two) or relaxation (group three) twice a week for four weeks. Only acupuncture group one and the relaxation group were provided with the additional suggestion that the treatment might strengthen the immu ...
Deqi switches off brain's pain regions
Categories: Miscellaneous, Acupuncture research
Acupuncture that elicits deqi has a deactivating effect on specific areas of the brain associated with pain processing. A UK team has investigated the effect of deqi and acute pain needling sensations on brain fMRI blood oxygen level-dependent (BOLD) signals. Seventeen healthy participants received acupuncture at Hegu L.I.-4 while in an MRI scanner. The fMRI measurements were classified into those ...
Acupuncture more than a placebo for pain
Categories: Miscellaneous, Acupuncture research
In order to clarify whether acupuncture is more effective than placebo for pain relief, two British authors have combined evidence gathered from systematic reviews of high-quality RCTs that compared acupuncture with sham acupuncture for chronic pain conditions. Eight systematic reviews with meta-analyses of pooled data were included in their analysis. For short-term outcomes, acupuncture showed si ...
Acupuncture safe, risks negligible
Categories: Acupuncture research
Two prospective surveys conducted among different groups of professionals in the UK, including doctors, physiotherapists and practitioners primarily trained in acupuncture, monitored adverse events to acupuncture over a defined period of time. A total of 652 acupuncturists reported 6733 adverse reactions in 66,229 patients, an adverse event rate of 10.2%. The most common events were tiredness (3%) ...
Acupuncture increases nitric oxide synthesis
Categories: Acupuncture research
Acupuncture significantly increases the concentration of nitric oxide (NO, a key biological signalling molecule involved in vasodilation and neurotransmission) in local body tissues. In a randomised, double-blind, crossover study, 20 volunteers underwent one session each of real and non-invasive sham acupuncture in a single hand and forearm, with a one-week interval between treatments. NO concentr ...
Needle manipulation has cellular consequences
Categories: Acupuncture research
Subtle differences in needle manipulation techniques can affect the cellular response of connective tissue to acupuncture. American researchers subjected subcutaneous tissue samples from mice to varying amounts of bidirectional needle rotation, before examining them by confocal microscopy. Fibroblast cells were observed to respond to bidirectional rotation with morphological changes, which occurre ...
Acupuncture's ant-inflammatory effects
Categories: Acupuncture research
Research has shown that the parasympathetic nervous system, and in particular the vagus nerve, plays an important part in the regulation of the immune system. A new review explains the neuroimmunoendocrine mechanisms that underlie this interaction, emphasising the role of the vagus nerve in an 'inflammatory reflex' which is capable of suppressing inflammation. Since acupuncture and other CAM modal ...
Imaging acupuncture channels
Categories: Acupuncture research
Two different imaging methods have provided evidence for the existence of acupuncture channels. In one Chinese study, the optical transport properties along the Pericardium channel path and a parallel non-channel path one centimetre away from it were measured. Lasers were shone onto volunteers' arms on points at one end of the path and the amount of emitted light was measured at points on the othe ...
Characterisation of deqi
Categories: Acupuncture research
An experimental study has been carried out using fMRI to characterise the nature and cause of the sensations experienced during deqi. Manual acupuncture was performed at Hegu L.I.-4, Zusanli ST-36 and Taichong LIV-3 during fMRI in 42 acupuncture-naive healthy adult volunteers. Non-invasive tactile stimulation was delivered to the acupoints by gentle tapping with a blunt metal filament prior to acu ...
