Double-blind acupuncture needles: a multi-needle, multi-session randomized feasibility study.

ABSTRACT: Background:Efficacy of acupuncture is difficult to demonstrate without a feasible double-blind milieu. Double-blind acupuncture needles have been validated in single session protocols with one or two needles but not been tested in a protocol requiring many needles and repeated sessions. Methods:We determined the feasibility of a 13-needle, 10-session study protocol. Feasibility focused on (1) enrolling and retaining participants; (2) two acupuncturists accurately implementing a double-blind, multi-needle, multi-session protocol; (3) participants completing measures; and (4) protocol acceptability to participants. In this double-blind randomized controlled pilot study, participants were randomized 1:1 to a penetrating needle group or a skin-touch placebo control group. Results:Six women with vulvodynia (mean age 31.5?±?8 years; five white, non-Latina, one black/African American) met the eligibility requirements, consented to participation, and were enrolled. All six participants (100%) completed the 10-session study protocol in 5 weeks without missing any treatment sessions. Per observed checklist documented technique, two acupuncturists flawlessly administered the 13-needle, 10-session acupuncture protocol; no needles malfunctioned. Six participants attended all sessions and completed 99% of measurement items. One participant did not like acupuncture (60% acceptability score) and five liked acupuncture (100% acceptability scores); the mean acceptability score was 93.3%. Conclusion:Study feasibility was supported. This protocol can be used in a double-blind efficacy trial of acupuncture for vulvodynia. Trial registration:ClinicalTrials.gov, NCT02704234. Registered 30 November 2015.

Project description:BACKGROUND:The aim of this study was to compare the short-term and intermediate-term efficacy of acupuncture plus fire needle therapy with that of acupuncture alone in the treatment of lateral epicondylitis (LE). METHODS:Thirty-eight patients with LE who had persisted for at least 2 months were enrolled in this prospective, assessor-blinded, randomized controlled pilot trial. Twenty-one patients were randomized to the acupuncture plus fire needle group and 17 to the acupuncture-only group. The primary outcome was the visual analog scale pain score for the previous 24?hours and the secondary outcomes were the maximum grip strength, Patient-rated Forearm Evaluation Questionnaire score, and Medical Outcomes Study 36-Item Short-form Health Survey score. The values at baseline (pretreatment), at the end of treatment, and at 3 months after treatment were used to assess the short-term and intermediate-term effects of treatment. The data were analyzed using the Chi-square test and t test. RESULTS:Within-group analyses showed better results for acupuncture plus fire needle therapy in the short term and intermediate term. Differences in the severity of pain and secondary outcomes were significant in the intermediate term in the acupuncture group. At the end of treatment, none of the differences in outcome scores were significant, except for maximum grip strength in the affected hand in the acupuncture group. No significant between-group differences in short-term or intermediate-term outcomes were observed. CONCLUSION:Acupuncture plus fire needle therapy was effective in the short term in patients seeking improvement of LE. Twelve treatments were effective for relieving pain and improving disability in the intermediate term in patients with chronic LE in both study groups. The findings of the pilot study confirm the feasibility of proceeding to a larger randomized controlled study of the longer-term effects of acupuncture plus fire needle therapy in patients with LE.

Project description:BackgroundIn pig husbandry, most piglets receive an intramuscular injection with iron around three days of age for the prevention of hypochromic, microcytic anaemia. In recent years an increased interest is noted for needle-free injections, because of efficiency and safety for man and animal. This study aims to support the evidence on efficacy to extent the registration of a commercial iron supplement with a needle-free administration application. To this aim the study has two objectives: 1) to determine the effect of needle-free injection of the iron supplement on the mean blood Haemoglobin level at weaning, as primary outcome, and mean Haematocrit and mean Body weight of pigs at weaning as secondary outcome compared to no treatment, as main determinant of iron deficiency anaemia in piglets at time of weaning; 2) to compare the effects of needle-free administration of the iron supplement with regular injection by needle, with regard to the course over time of Haemoglobin, Haematocrit, piglet growth and the differentiated haematological and serum iron parameters.MethodsA double blind randomized controlled trial was conducted with 72 piglets, 8 piglets per litter from 9 litters. At three days of age pigs were selected, based on body weight, and random allocated to three study groups: a) control non-treated group (2 pigs per litter, 18 in total), b) a group with regular iron injection by needle injection (3 pigs per litter, 27 in total), c) a group that received iron by needle-free injection (3 pigs per litter, 27 in total). At four points in time (day 3, 14, 26 and 40) piglets were weighed and bled to analyse the dynamics of red blood counts and haematological parameters as well as serum iron parameters. The primary outcome parameter was the Haemoglobin (Hb) level on day 26. Of secondary importance were Haematocrit (Ht) and body weight (BW) at weaning and parameters with tertiary importance were the course of Hb, Ht and differentiated red blood cell parameters, serum iron, iron binding capacity and iron saturation. In the statistical analyses, linear mixed effect regression modelling was used to account for repeated measures within litters and pigs.ResultsThe analyses showed that needle-free administration was as efficacious to prevent iron deficiency anaemia at day 26 as administration using regular needle injection, compared to the control group. The mean level of Hb and Ht of pigs in the needle and needle-free group did not differ significantly. No side effects were observed.ConclusionIt is concluded that needle-free iron administration of the tested product is as efficacious as regular administration by needle injection.
