Acupuncture for perceived stress in pregnant women: an intervention study

OBJECTIVE

To analyze the effects of acupuncture in the treatment of perceived stress in pregnant women.

METHOD

A before-after intervention study, carried out in a primary health unit in Fortaleza-Ceará, with 56 pregnant women. The pregnant women underwent six acupuncture sessions, with two 30-minute sessions per week.

RESULTS

After the intervention, there was a significant decrease in the scores of the following scale items: being upset, inability to control, nervousness, tiredness, anger, and inability to overcome stress. (p < 0.05). There was a significant increase in the score of the item control of situations (p = 0.003). There was a significant difference in the mean perceived stress of the initial session compared to the 1st, 2nd and 3rd week sessions (p < 0.001).

The use of acupuncture to treat stress during pregnancy reduced the stress perceived by pregnant women.

Acupuntura no estresse percebido em gestantes: um estudo de intervenção

RESUMO Objetivo: Analisar os efeitos da acupuntura no tratamento de estresse percebido em gestantes. Método: Estudo de intervenção do tipo antes e depois, realizado em unidade básica de saúde de Fortaleza-Ceará, com 56 gestantes. As gestantes realizaram seis sessões de acupuntura, com periodicidade de duas sessões por semana e duração de 30 minutos.

Resultados: Após a intervenção, houve uma diminuição significativa na pontuação dos seguintes itens da escala: preocupação, incapacidade de controle, nervosismo, cansaço, fúria e incapacidade de superar o estresse (p < 0,05). Observou-se aumento significativo na pontuação do item controle das situações (p = 0,003). Houve diferença significativa na média de estresse percebido da sessão inicial em relação às sessões da 1ª, 2ª e 3ª semana (p < 0,001).

Acupuncture for Psychosomatic Symptoms of Hwa-byung, an Anger Syndrome: A Feasibility Randomized Controlled Trial

Objectives: Emerging studies found the potential effects of acupuncture for treating chronic pain and mental disorders, namely, depressive and anxiety disorders. Acupuncture is widely used for treating culture-related anger syndrome, Hwa-byung. This pilot trial aimed to investigate the feasibility of a clinical trial testing acupuncture for the psychosomatic symptoms of Hwa-byung.

Methods: A total of 26 patients with Hwa-byung planned to be randomly assigned to the acupuncture or sham acupuncture groups. About 10 treatment sessions were applied over 4 weeks. The 100-mm visual analog scale was used to measure the six major Hwa-byung symptoms: stuffiness in the chest, heat sensations, pushing-up in the chest, feeling a mass in the throat, feelings of unfairness, and hard feelings. The criteria for assessing the success of this pilot trial were defined as improvement in three or more of the six Hwa-byung symptoms after treatment, with an effect size >0.2.

Results: A total of 15 patients were finally included and randomly assigned to the acupuncture group (n = 7) or the sham acupuncture group (n = 8). After 10 treatment sessions, the Cohen's d effect sizes for acupuncture compared to sham acupuncture were >0.2 for each one of the six major Hwa-byung symptoms, which met our a priori criteria for success. Also, the effect size for the somatic symptoms of “stuffiness in the chest” was 0.81 (95% CI −0.40, 2.20), referring to a large effect size.

Conclusions: Our results suggest that acupuncture treatment would be regarded as an acceptable intervention for a full-scale study of psychosomatic symptoms in patients with Hwa-byung.
