[escepticos] Acupuntura y dolor de espalda

[Felipe Martínez-Pastor]

Lo interesante es lo que sigue, y creo que no hace falta ningún
comentario. Sólo que habría que decir a esos señores que dejen de
torturar el mensaje y que hablen de "acupuntura" únicamente cuando se
refieran a la de verdad. Claro, que si fuese así no podrían decir que
funciona...  ¿por qué no hacen creer a los pacientes que les clavan
agujas sin clavárselas? Seguro que se llevaban una sorpersa.

La cosa es aguantar ahí todo lo que se pueda, no vayamos a acabar con el
negocio.

Response rate was defined as a 33 percent improvement in pain or a 12
percent improvement in functional ability. “At six months, response rate
was 47.6 percent in the verum acupuncture group, 44.2 percent in the
sham acupuncture group and 27.4 percent in the conventional therapy
group,” the authors note. “Differences among groups were as follows:
verum vs. sham, 3.4 percent; verum vs. conventional therapy, 20.2
percent; and sham vs. conventional therapy, 16.8 percent.”

“The superiority of both forms of acupuncture suggests a common
underlying mechanism that may act on pain generation, transmission of
pain signals or processing of pain signals by the central nervous system
and that is stronger than the action mechanism of conventional therapy,”
the authors conclude. “Acupuncture gives physicians a promising and
effective treatment option for chronic low back pain, with few adverse
effects or contraindications. The improvements in all primary and
secondary outcome measures were significant and lasted long after
completion of treatment.”
