The Therapeutic Value Of Meditation Unproven, Study Found

"There is an enormous amount of interest in using
meditation as a form of therapy to cope with a
variety of modern-day health problems, especially
hypertension, stress and chronic pain, but the
majority of evidence that seems to support this
notion is anecdotal, or it comes from poor quality
studies," say Maria Ospina and Kenneth Bond,
researchers at the University of Alberta/Capital
Health Evidence-based Practice Center in Edmonton, Canada.
In compiling their report, Ospina, Bond and their
fellow researchers analyzed a mountain of medical
and psychological literature - 813 studies in all -
looking at the impact of meditation on conditions
such as hypertension, cardiovascular diseases and
They found some evidence that certain types of
meditation reduce blood pressure and stress in
clinical populations. Among healthy individuals,
practices such as Yoga seemed to increase verbal
creativity and reduce heart rate, blood pressure
and cholesterol. However, Ospina says no firm
conclusions on the effects of meditation practices
in health care can be drawn based on the available
evidence because the existing scientific research
is characterized by poor methodological quality and
does not appear to have a common theoretical perspective.
"Future research on meditation practices must be more
rigorous in the design and execution of studies and
in the analysis and reporting of results," Ospina explains.
But the researchers caution against dismissing the
therapeutic value of meditation outright. "This
report's conclusions shouldn't be taken as a sign
that meditation doesn't work," Bond says. "Many
uncertainties surround the practice of meditation.
For medical practitioners who are seeking to make
evidence-based decisions regarding the therapeutic
value of meditation, the report shows that the
evidence is inconclusive regarding its effectiveness."
For the general public, adds Ospina, "this research
highlights that choosing to practice a particular
meditation technique continues to rely solely on
individual experiences and personal preferences,
until more conclusive scientific evidence is produced."
The report, published June 2007 and titled Meditation
Practices for Health: State of the Research, identified
five broad categories of meditation practices: mantra
meditation, mindfulness meditation, Yoga, Tai Chi and
Qi Gong. Transcendental Meditation and relaxation
response (both of which are forms of mantra meditation)
were the most commonly studied types of meditation.
Studies involving Yoga and mindfulness meditation were
