A recent meta-study in the World Journal of Gastroenterology (March 28 2017) – Systematic review: The placebo effect of psychological interventions in the treatment of irritable bowel syndrome
Aim – “To determine the placebo response rate associated with different types of placebo interventions used in psychological intervention studies for irritable bowel syndrome.” (Six studies, with a total of 555 patients met the inclusion criteria.)
… and the placebo effect, unsurprisingly, figures significantly:
“Contrary to our expectations, the PRR (Placebo Response Rate) in studies on psychological interventions was comparable to that in studies on pharmacological, dietary and alternative medical interventions.”
The research effort on the placebo effect deepens and widens.
“In a report published online Feb. 15 in The BMJ, researchers at Stanford call for more health care providers to place emphasis on the importance of individual mindsets and social context in healing … (and) to develop more studies that measure the physical effects of these psychosocial elements to understand and quantify patients’ subjective experiences of expectations, connection and trust.”
“We have long been mystified by the placebo effect,” Crum said. “But the placebo effect isn’t some mysterious response to a sugar pill. It is the robust and measurable effect of three components: the body’s natural ability to heal, the patient mindset and the social context. When we start to see the placebo effect for what it really is, we can stop discounting it as medically superfluous and can work to deliberately harness its underlying components to improve health care.”
Many people take glucosamine and chondroitin supplements for arthritis pain, but a controlled trial has found no evidence that the combination works. In fact, in this study, the placebo worked better.
Spanish researchers randomized 164 men and women with knee osteoarthritis to take a single daily dose of 1,500 milligrams of glucosamine and 1,200 of chondroitin, or an identical looking placebo. The study is in Arthritis & Rheumatology.
‘VR Placebo interventions’ …! We do indeed live in a time of wonders. Research is being undertaken into the value of the emerging Virtual Reality technologies in treatment of mental illness. It’s early days, but the results so far are promising. Read more here.
“The study included about 300 kids aged 8 to 17, enrolled at 31 centers. They had 11 migraines on average in the month before the study began and were randomly assigned to take either of the drugs or placebo pills daily for six months. Migraine frequency in the study’s last month was compared with what kids experienced before the study. At least half of kids in each group achieved the study goal, reducing migraine frequency by half.”
The same report, with a couple of videos, is over at CBS.
Scientists have identified for the first time the region in the brain responsible for the “placebo effect” in pain relief, when a fake treatment actually results in substantial reduction of pain, according to new research from Northwestern Medicine and the Rehabilitation Institute of Chicago (RIC).

‘As most of us would guess, the placebo perceived by patients to be more expensive worked better than its seemingly lower-cost equivalent … Perceptions of cost are capable of altering the placebo response,.
Quite a buzz lately about the placebo effect and back pain, extending from a randomized control trial in Portugal.
“Our findings demonstrate the placebo effect can be elicited without deception. Patients were interested in what would happen and enjoyed this novel approach to their pain. They felt empowered.” – Lead author Claudia Carvalho, Ph.D., ISPA
“It’s the benefit of being immersed in treatment: interacting with a physician or nurse, taking pills, all the rituals and symbols of our healthcare system,” (says placebo researcher Ted Kaptchuk, Professor of Medicine at Harvard Medical School). “The body responds to that.”
While this study focused on chronic pain, Kaptchuk says it is possible that patients with other conditions that involve self-observation – such as fatigue, depression, or digestive problems – may benefit from open-label placebo treatment.
“You’re never going to shrink a tumor or unclog an artery with placebo intervention,” notes Kaptchuk. “It’s not a cure-all, but it makes people feel better, for sure. Our lab is saying you can’t throw the placebo into the trash can. It has clinical meaning, it’s statically significant, and it relieves patients. It’s essential to what medicine means.”
There’s so much attention right now given to Olympic atheletes’ use of ‘placebo’ rituals and objects, from favourite items of underwear to ancient Chinese ‘cupping’ techniques and herbal supplements.
“Judo gold medalist Kayla Harrison wears the lucky socks that were a gift from her grandmother. Hockey player Alex Danson spins her stick 15 times before each game. Tennis player Rafael Nadal takes alternating sips from two water bottles at every break between games.”
“In sports, it’s a little different in that in the vast majority of cases relying on the placebo effect probably won’t hurt, and in many cases might actually help because of the power of belief. Aside from some potential BO, is it really a problem that an athlete regularly wears the same t-shirt under his uniform to help with on-field success? In fact, savvy coaches regularly use various placebo approaches when trying to help their team with belief — and often these tactics work.”
