Acupuncture in the treatment of rheumatoid arthritis: a double-blind controlled pilot study

<p>Abstract</p> <p>Background</p> <p>In planning a randomized controlled trial of acupuncture, we conducted a pilot study using validated outcome measures to assess the feasibility of the protocol, and to obtain preliminary data on efficacy and tolerability of 3 different forms of acupuncture treatment as an adjunct for the treatment of chronic pain in patients with Rheumatoid arthritis (RA).</p> <p>Methods</p> <p>The study employs a randomized, prospective, double-blind, placebo-controlled trial to evaluate the effect of electroacupuncture (EA), traditional Chinese acupuncture (TCA) and sham acupuncture (Sham) in patients with RA. All patients received 20 sessions over a period of 10 weeks. Six acupuncture points were chosen. Primary outcome is the changes in the pain score. Secondary outcomes included the changes in the ACR core disease measures, DAS 28 score and the number of patients who achieved ACR 20 at week 10.</p> <p>Results</p> <p>From 80 eligible patients, 36 patients with mean age of 58 ± 10 years and disease duration of 9.3 ± 6.4 years were recruited. Twelve patients were randomized to each group. Twelve, 10 and 7 patients from the EA, TCA and Sham group respectively completed the study at 20 weeks (p < 0.03); all except one of the premature dropouts were due to lack of efficacy. At week 10, the pain score remained unchanged in all 3 groups. The number of tender joints was significantly reduced for the EA and TCA groups. Physician's global score was significantly reduced for the EA group and patient's global score was significantly reduced for the TCA group. All the outcomes except patient's global score remained unchanged in the Sham group.</p> <p>Conclusion</p> <p>This pilot study has allowed a number of recommendations to be made to facilitate the design of a large-scale trial, which in turn will help to clarify the existing evidence base on acupuncture for RA.</p> <p>Trial registration</p> <p>ClinicalTrials.gov NCT00404443</p

Efeitos da craniopuntura de Yamamoto na osteoartrite de joelho: estudo de caso

O objetivo deste estudo foi verificar os efeitos da craniopuntura de Yamamoto na dor, na amplitude de movimento, qualidade de vida e funcionalidade de paciente com osteoartrite (OA) de joelho. Foi realizado um estudo de caso de uma paciente de 59 anos apresentando quadro de dor no joelho, redução funcional nos últimos três meses e radiografia constando o grau 3 de OA de joelhos. A avaliação foi feita antes e após o tratamento através da Escala Visual Analógica (EVA) para avaliação da dor, da qualidade de vida pelo questionário Western Ontario and McMaster Universities Osteoarthritis (WOMAC), da funcionalidade pelo Knee injury and Osteoarthritis Outcome Score (KOOS) e da amplitude de movimento do joelho pela goniometria. A craniopuntura foi realizada duas vezes por semana, com duração de 40 minutos cada, totalizando 10 sessões. A análise dos dados foi feita de forma descritiva. A variável utilizada foi o ganho relativo (GR) medido no pré e no pós-tratamento. A dor no joelho diminuiu (GR=100%), enquanto a amplitude de movimento aumentou em ambos os joelhos (GR=20%). Observou-se melhora na dor (GR=83%), na rigidez (GR=50%), na função (GR=80%) e no escore total da WOMAC (GR= 79%). Verificou-se, através da KOOS, melhora nos sintomas (GR=8%), na dor (GR=26%), nas atividades de vida diária (GR=21%) e na qualidade de vida (GR= 17%). Conclui-se que a craniopuntura foi efetiva no alívio da dor, na amplitude de movimento, qualidade de vida e funcionalidade de paciente com OA de joelho.The purpose of this study was to investigate the effects of Yamamoto New Scalp Acupuncture in pain, range of motion, life quality and functionality of patients with knee osteoarthritis (OA). We conducted a case study of a patient of 59 years complaining of knee pain, functional reduction in the last three months and radiography consisting of grade 3 knee OA. The evaluation was done before and after treatment using the Visual Analogue Scale index (VAS) for pain assessment, life quality by Western Ontario and McMaster Universities Osteoarthritis index (WOMAC), the functionality for Knee injury and Osteoarthritis Outcome Score index (KOOS) and range of motion of the knee by goniometry. The craniopuncture was performed twice on week, lasting 40 minutes, totaling 10 sessions. Data analysis was performed descriptively. The variable used was the relative gain (GR) measured before and after treatment. The knee pain decreases (GR=100%), while the range of motion increases in both knees (GR=20%). An improvement in pain (GR=83%), stiffness (GR = 50%), function (GR = 80%) and total score of WOMAC (GR=79%). By KOOS, it was found, improvement in symptoms (GR=8%), pain (GR=26%) in activity od daily living (GR=21%) and life quality (GR=17%). We conclude that the craniopuncture was effective in pain relieving, motion range, life quality and functionality of patient with knee osteoarthritis
