Controlling Practitioner–patient Relationships in Acupuncture Trials: A Systematic Review and Meta-Regression

The Effectiveness and Safety of Acupuncture on Suicidal Behavior: A Systematic Review

In situations where death by suicide is a major global issue and effective prevention and management approaches are lacking, acupuncture improves some risk factors for suicide, including depression, and it has been used for a long time in clinical settings. Herein, we aimed to assess the effectiveness and safety of acupuncture in the treatment of suicidal behaviors. Fourteen electronic databases were searched for studies published up to 7 September 2022. Original interventional studies of acupuncture in suicide prevention were included. The primary outcome was the validated measure of suicidal ideation. The risk of bias in the included studies was assessed using an appropriate assessment tool. Due to the heterogeneity of the included studies, only qualitative analyses were conducted. Eight studies on manual acupuncture (50%), electro-acupuncture (37.5%), and acupressure (12.5%) were included. In particular, three studies (37.5%) used the National Acupuncture Detoxification Association protocol to stimulate the bilateral sympathetic, Shenmen, kidney, liver, and lung auricular points. Acupuncture was effective in direct and indirect outcomes related to suicidal behavior, not only for participants with suicidal behavior, but also for those with other conditions, including depression. A decrease in salivary cortisol was the only biological indicator of acupuncture in patients with suicidal ideation. However, the methodological quality of the included studies was not optimal. In conclusion, acupuncture may reduce the risk of suicidal behavior in clinical and non-clinical populations. Owing to clinical heterogeneity, low methodological quality, and the small number of included studies, further high-quality studies should assess the effectiveness of acupuncture.

Experienced Practitioners' Beliefs Utilized to Create a Successful Massage Therapist Conceptual Model: a Qualitative Investigation

Background

The massage therapy profession in the United States has grown exponentially, with 35% of the profession’s practitioners in practice for three years or less. Investigating personal and social factors with regard to the massage therapy profession could help to identify constructs needed to be successful in the field.

Purpose

This data-gathering exercise explores massage therapists’ perceptions on what makes a successful massage therapist that will provide guidance for future research. Success is defined as supporting oneself and practice solely through massage therapy and related, revenue-generating field activity.

Participants and Setting

Ten successful massage therapy practitioners from around the United States who have a minimum of five years of experience.

Research Design

Semistructured qualitative interviews were used in an analytic induction framework; index cards with preidentified concepts printed on them were utilized to enhance conversation. An iterative process of interview coding and analysis was used to determine themes and subthemes.

Results

Based on the participants input, the categories in which therapists needed to be successful were organized into four main themes: effectively establish therapeutic relationships, develop massage therapy business acumen, seek valuable learning environments and opportunities, and cultivate strong social ties and networks. The four themes operate within specific contexts (e.g., regulation and licensing requirements in the therapists’ state), which may also influence the success of the massage therapist.

Conclusions

The model needs to be tested to explore which constructs explain variability in success and attrition rate. Limitations and future research implications are discussed.

The role of touch in acupuncture treatment

Acupuncture is a therapeutic treatment that is characterised by the insertion of a needle at a particular location on the body. Acupuncture stimulation includes sensory-discriminative and affective-social touch dimensions. In this review, we discuss the role of touch during acupuncture stimulation with an emphasis on the therapeutic, sensory-discriminative and affective-social aspects. In the discriminative dimension, de qi, which is associated with needling, includes a combination of various sensations, such as heaviness, numbness, soreness and distension. Achieving the appropriate de qi sensation appears to be fundamental to the therapeutic outcome following acupuncture treatment. In the affective dimension, the acupuncture procedure typically includes gentle manual touch stimulation, which induces feelings of calm and well-being, perhaps by activating C tactile fibres. Enhanced activity of C tactile afferents may induce a 'limbic touch' response, resulting in emotional and hormonal reactions. Because acupuncture is a 'therapist intensive' and complex intervention, it is necessary to understand the role of social touch between the practitioner and patient. Both sensory-discriminative and affective-social touch aspects play an important role in the therapeutic effect of acupuncture treatment in clinical practice.

Providing acupuncture in a breast cancer and fatigue trial: The therapists' experience

OBJECTIVE

To explore the experiences of therapists providing acupuncture in a trial context, to women with fatigue, following breast cancer treatment.

METHODS

The focus groups were nested within a multi-site randomised control trial. Therapists (n = 15) involved in the trial were invited to participate in one of the focus groups, which took place in the north and south of England. The treatment protocol imposed constraints on dialogue to essential procedural conversation and stipulated needling times of 20 min.

RESULTS

All 15 therapists (100%) participated. Whilst they reported learning more about fatigue and cancer, adhering to the trial protocol limited the holistic nature of their practice. Seeing improvements, despite the protocol, made some therapists question their practice, in terms of needling times and limiting dialogue.

CONCLUSIONS

The study provided information about the therapists' perspective of working within a trial. This could have implications for providing acupuncture treatments more cost effectively and timely within clinical practice.

Association of Pre- and Post-Treatment Expectations with Improvements after Acupuncture in Patients with Migraine

Objective

To study whether a higher expectation of acupuncture measured at baseline and after acupuncture is associated with better outcome improvements in patients with migraine.

Methods

We performed a secondary analysis of a previous published trial in which 476 patients with migraine were randomly allocated to three real acupuncture groups and one sham acupuncture control group. All the participants received 20 sessions of acupuncture over a 4-week period. The primary outcome was the number of days with a migraine attack (NDMA) assessed at 5–8 weeks after randomisation. The secondary outcomes were visual analogue scale, headache intensity and quality of life assessed at 4, 8 and 16 weeks after randomisation. Expectations of the acupuncture effect were assessed at baseline and at the end of treatment and categorised into five levels, with 0% the lowest and 100% the highest. Outcome improvement was first compared among the participants with different expectation levels using an analysis of variance model. The association between expectations of treatment and outcome improvement was then calculated using a logistic regression model.

Results

Patients with 100% baseline expectations did not report significantly fewer NDMA than those with 0% baseline expectations after adjusting for the covariates (at 5–8 weeks, 1.7 vs 3.9 days, p=0.987). High baseline expectations had no significant impact on improvement of the primary outcome (100% vs 0%: OR 8.50, 95% CI 0.89 to 191.65, p=0.682). However, patients with 100% post-treatment expectations reported fewer NDMA than those with 0% expectations (primary outcome: 1.3 vs 5.0 days, p<0.001) and were more likely to have a favourable response (100% vs 0%: OR 68.87, 95% CI 6.26 to 1449.73, p=0.002). Similar results were found when analysing the impact of expectation on the secondary outcomes.

Conclusions

A high level of expectation after acupuncture treatment rather than at baseline was associated with better long-term outcome improvements in patients with migraine.

Problems caused by heterogeneity in meta-analysis: a case study of acupuncture trials

OBJECTIVES

To illustrate the pitfalls of using meta-analysis to combine estimates of effect in trials that are highly varied and have a high potential for bias.

METHODS

We used a random-effects meta-analysis to pool the results of 51 sham-controlled acupuncture trials of chronic pain published in English before 2008 and explored the heterogeneity using meta-regression. We repeated the process on a subset of these trials that used a visually credible non-penetrating sham device as control (N = 12).

RESULTS

In both analyses there were high levels of heterogeneity and many studies were at risk from potential bias. The heterogeneity was not explained by meta-regression.

CONCLUSIONS

Trials of interventions that have high potential for bias, such as many in the acupuncture literature, do not meet the assumptions of the statistical procedure that underlie random-effects meta-analysis. Even in the absence of bias, heterogeneity in meta-analyses is not accounted for by the CIs around the pooled estimate.
