An independent review of studies of ‘energy medicine’
funded by the US National Center for Complementary
and Alternative Medicine
Edzard Ernst, Robert Seip
Abstract
The US National Center for Complementary and Alternative Medicine (NCCAM) has frequently been criticised for funding
research that is less than rigorous. Our aim was to review NCCAM-funded clinical trials of ‘energy medicine’. We searched
MEDLINE to locate all NCCAM-funded studies of energy medicine. Data were extracted by two independent reviewers
according to predefined criteria. Five RCTs were identified. Those with a low risk of bias showed no effect beyond placebo.
Testing implausible treatments in clinical trials is wasteful and perhaps even detrimental.

Introduction
The National Center for Complementary and Alter-
native Medicine (NCCAM) grew out of the US
Office of Alternative Medicine, which was founded
in 1992.
1
As an NIH centre, NCCAM enjoys an
autonomy similar to that of NIH’s other institutes
and centers.
2
From the beginning, a key aim of the
centre was to conduct clinical research into CAM
‘with strict scientific rigour’;
3
a major emphasis was
put on clinical trials. Over time, NCCAM’s budget
has steadily risen from US$50 million in 1999 to
US$128.8 million in 2010.
4
Historically, 70–80% of
this money has been invested in clinical trials.
1
The strategy of conducting trials of biologically
implausible interventions has been challenged
repeatedly. Critics have argued that some of the
studies funded by NCCAM are ‘of dubious merit’
1
and
that an independent review of the centre is urgently
needed.
5,6
The former director of NCCAM, however,
countered this argument, stating that ‘NCCAM was
created to foster and build a research enterprise that
subjects complementary and alternative medicine to
open-minded, hypothesis driven investigation’.
7
The NCCAM’s strategic plan for 2005–2009 specifi-
cally addresses the centre’s approach to the study of
‘energy medicine’, stating that it is their intention
to apply ‘. . . the same standards used in designing
experiments in physics, chemistry, and other scien-
tific disciplines’.
4
Whether this has eventuated is
unclear. Thus, the aim of this article is to review the
evidence generated by NCCAM-funded RCTs in the
field of energy medicine.
Methods
The search term ‘AT [gr]’ or ‘NCCAM[gr]’ (provided
by the NCCAM website) was used to identify all RCTs
sponsored by NCCAM and reported in MEDLINE.
The search was limited to ‘Clinical Trial’, ‘Random-
ized Controlled Trial’, ‘Clinical Trial, Phase I’ ‘Clinical
Trial, Phase II’, ‘Clinical Trial, Phase III’, ‘Clinical
Trial, Phase IV’ and ‘Controlled Clinical Trial’. From
