Willow Curve Device for Pain: Strong Claims, Weak Evidence

Willow Curve is advertised as the “world’s first digital anti-inflammatory device”, “a laser smart device” designed to relieve joint pain with thermal and photonic energy. It contains over 150 bio-sensory and bio-therapeutic components that continuously monitor the body’s thermal and electrical response to the device, and computer chips use that information to tailor a digital prescription on the fly. That prescription consists...

Galvanic Skin Response Pseudoscience

Selling snake oil is all about marketing, which means that a good snake oil product needs to have a great angle or a hook. Popular snake oil hooks include being “natural,” the product of ancient wisdom, or “holistic.” Perhaps my favorite snake oil marketing ploy, however, is claiming the product represents the latest cutting-edge technology. This invariably leads to humorous sciencey technobabble....

Cryotherapy: A Layman’s Attempt to Understand the Science

NOTE: I get a lot of emails asking me whether treatment X is evidence-based or a scam. This one was different. Zachary Hoffman had done his homework and had already answered the question for himself (at least, as well as it could be answered with the existing published evidence). I asked him to write up his findings as a guest post for...

New FDA regulatory role threatens bogus diagnostic tests

The FDA regulates in vitro diagnostic devices (IVDs) as medical devices. IVDs analyze human samples, such as blood, saliva, tissue and urine. However, in the past, the agency did not use its authority to regulate what are known as “laboratory-developed tests” (LDTs), tests developed and performed at a single laboratory, with all samples sent to that particular lab for testing. Instead, it...

Do doctors pay attention to negative randomized clinical trials?

We at the Science-Based Medicine blog believe that all medicine, regardless of where it comes from, should be held to a single science-based standard with regards to efficacy, effectiveness, and safety. We tend to focus primarily on “complementary and alternative medicine” (CAM), now more commonly known as “integrative medicine,” because (1) we believe it to be undermining the scientific basis of medicine...

Point-of-Care Ultrasound: The Best Thing Since Stethoscopes?

A bit of good news for a change: a “Perspective” article in the New England Journal of Medicine describes how point-of-care ultrasound devices are being integrated into medical education. The wonders of modern medical technology are akin to science fiction. We don’t yet have a tricorder like “Bones” McCoy uses on Star Trek, but we are heading in that direction, and the...

E-cigarettes: The growing popularity of an unregulated drug delivery device

This post is not about vaccines (for a change). However, I deem it appropriate to mention that one of the topics that I blog most frequently about is vaccines and how the antivaccine movement pushes pseudoscience and quackery based on its apparently implacable hatred of vaccines. (You’ll see why very shortly.) It seems almost as long as my interest in the topic...

Will Your Smartphone Become a Tricorder?

The Star Trek universe is a fairly optimistic vision of the future. It’s what we would like it to be – an adventure fueled by advanced technology. In the world of Star Trek technology makes life better and causes few problems. One of the most iconic examples of Star Trek technology is the medical tricorder. What doctor has not fantasized about walking...

Bogus Electrodermal Testing Devices and the Failure of Regulators to Act

Electrodermal testing is a bogus procedure where measurements of skin conductance with a biofeedback device are entered into a computer to diagnose nonexistent health problems and “energy imbalances” and to recommend treatments for them, often involving the sale of homeopathic remedies and other useless products. It falls under the general category of EAV (Electro Acupuncture of Voll). The history and variants of...

Molecular breast imaging (MBI): A promising technology oversold in a TED Talk?

Occasionally, there are topics that our readers want — nay, demand — that I cover. This next topic, it turns out, is one of them. It’s a link to a TED Talk. I’m guessing that most of our readers have either viewed (or at least heard of) TED talks. Typically, they are 20-minute talks, with few or no slides, by various experts...
