Effectiveness of Acupuncture on Pain, Functional Disability, and Quality of Life in Rheumatoid Arthritis of the Hand: Results of a Double-Blind Randomized Clinical Trial.

BACKGROUND: Rheumatoid arthritis (RA) is characterized by pain, functional disability, poor quality of life (QoL), high socioeconomic impact, and annual costs of over $56 billion in the United States. Acupuncture (AC) is widely in use; however, studies show severe methodological shortcomings, did not consider the functional diagnosis for the allocation of acupoints and their results showed no differences between verum and control groups. OBJECTIVE: The authors aimed to objectively assess the safety and efficacy of AC treatments for RA. METHODS: 105 RA patients with a functional diagnosis of a "Pivot syndrome" or "Turning Point syndrome" were randomly assigned to (1) verum-AC (verum acupoints), (2) control-AC (sham acupoints-points outside of the conduits/meridians and of the extra-conduits), or (3) waiting list (each group n = 35). AC groups experienced the exact same number, depth, and stimulation of needles. Assessments took place before and 5 min after AC with follow-ups over 4 weeks. RESULTS: (1) Verum-AC significantly improved self-reported pain (Z = -5.099, p < 0.001) and pressure algometry (Z = -5.086, p < 0.001); hand grip strength (Z = -5.086, p < 0.001) and arm strength (Z = -5.086, p < 0.001); health status improved significantly (p < 0.001, Z = -4.895); QoL improved significantly in 7/8 survey domains; and number of swollen joints (Z = -2.862, p = 0.004) and tender joints (Z = -3.986, p < 0.001) significantly decreased. (2) Control-AC showed no significant changes, except in self-reported pain improvement. (3) Waiting list group showed an overall worsening. CONCLUSION: This is the first double-blind controlled study on AC in RA of the hand that objectively and specifically assesses positive effects supporting its integration in rheumatology. Acupoint allocation according to Chinese Medicine functional diagnoses is extremely relevant to assess AC effectiveness in a patient group primarily defined by a "western" medicine diagnosis. Based on clear allocation criteria for acupoints, the authors minimized the possible bias of unspecific and suggestive effects on the control group, showed the specific effects of the points chosen, improved efficacy, and identified an evidence base for AC.

Immediate Pain Relief in Adhesive Capsulitis by Acupuncture-A Randomized Controlled Double-Blinded Study.

OBJECTIVE: Primary adhesive capsulitis (AC), or frozen shoulder, is an insidious and idiopathic disease. Severe pain is predominant in the first two of the three stages of the condition, which can last up to 21 months. DESIGN, SETTING, AND SUBJECTS: Sixty volunteers with primary AC were randomly assigned to acupuncture with press tack needles compared with press tack placebos in a patient- and observer-blinded placebo-controlled study. The participants were subsequently offered classical needle acupuncture in an open follow-up clinical application. Thirty-four volunteers received conservative therapy, including 10 classical needle acupuncture treatments over 10 weeks, 13 volunteers received conservative therapy without classical needle acupuncture. All subjects agreed to follow-up after one year. METHODS: Acupuncture treatment was performed using a specific distal needling concept, using reflex areas on distant extremities avoiding local treatment. RESULTS: An immediate improvement of 3.3 ± 3.2 points in Constant-Murley Shoulder Score (CMS) pain subscore was seen in the press tack needles group and of 1.6 ± 2.8 points in the press tack placebos group (P <0.02). Conservative therapy including classical needle acupuncture significantly improved the pain subscore within 14.9 ± 15.9 weeks compared with 30.9 ± 15.8 weeks with only conservative therapy (P < 0.001). CONCLUSION: The efficiency of distal needling acupuncture on immediate pain reduction was demonstrated in patients with AC and confirmed the applicability of press tack needles and press tack placebos for double-blind studies in acupuncture. Subsequent clinical application observation proved that results obtained with press tack needles/press tack placebos can be transferred to classical needle acupuncture. Integrating acupuncture with conservative therapy showed superior effectiveness with respect to the time course of the recovery process in AC compared with conservative therapy alone.

Evaluation of the effect of acupuncture on hand pain, functional deficits and health-related quality of life in patients with rheumatoid arthritis--A study protocol for a multicenter, double-blind, randomized clinical trial.

BACKGROUND: Rheumatoid arthritis (RA) is a systemic inflammatory disease characterized by functional disability and pain. Although acupuncture is widely used, until now Western acupuncture studies on RA have not shown conclusive positive results. Acupuncture is regarded as a reflex therapy that has effects on the human autonomic nervous system. By establishing a traditional Chinese medicine (TCM) diagnosis first, the practitioner is able to choose acupoints according to the state of each individual patient. METHODS/DESIGN: We are interested if acupuncture, using a classical diagnostic procedure to allocate acupoints to the patient according to the Shang Han Lun theory, can be effective in relieving pain, improving hand function and increasing health-related quality of life in RA.The authors intend to harmonize TCM diagnosis according to clinical and genetic profiles. Patients with the TCM diagnosis of a so-called Turning Point syndrome will be followed up in a randomized, prospective, double-blind, placebo-controlled, multicenter and three-armed parallel-group study with a standardized treatment in order to optimize potential therapeutic effects of acupuncture on pain, strength and muscle function of patients with RA as well as the influence on inflammation and quality of life. DISCUSSION: The findings of this study will provide important clinical information about the feasibility and efficacy of acupuncture treatment for RA patients. In addition, it will explore the feasibility of further acupuncture research. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov Identifier NCT02553005.
