A doctor who uses yoga in his practice

Saw this article in today’s New York Times and thought I’d share.

When patients with rotator cuff injuries do a pose derived from yoga, the results were as good or better than surgery or physical therapy. The yoga pose is headstand with the forearms making a triangle with the head, but you can do it against a wall — inversion is not required. It works by letting a new muscle do the work of the injured muscle.

Another study found that for patients with osteoporosis or its precursor osteopenia, ten minutes of yoga every day for two years built bone density in the hip and spine, while the controls lost bone density.

Yoga is weight-bearing exercise using the body’s own weight, especially in partial and full inversions. In addition, stretching pulls on the bone where muscles attach, and this can build bone density.

Another article is about piriformis syndrome, when the sciatic nerve is pinched by tight butt muscles. It can be caused by prolonged sitting.

Pressure-point massage can help. Some home exercises can provide relief in the majority of sufferers.

The gut’s “second brain” influences mood and well-being

This article from Scientific American is about the enteric nervous system (gut intelligence).

Some excerpts:

The second brain informs our state of mind in other more obscure ways, as well. “A big part of our emotions are probably influenced by the nerves in our gut,” Mayer says. Butterflies in the stomach—signaling in the gut as part of our physiological stress response, Gershon says—is but one example. Although gastrointestinal (GI) turmoil can sour one’s moods, everyday emotional well-being may rely on messages from the brain below to the brain above.

The enteric nervous system uses more than 30 neurotransmitters, just like the brain, and in fact 95 percent of the body’s serotonin is found in the bowels. Because antidepressant medications called selective serotonin reuptake inhibitors (SSRIs) increase serotonin levels, it’s little wonder that meds meant to cause chemical changes in the mind often provoke GI issues as a side effect. Irritable bowel syndrome—which afflicts more than two million Americans—also arises in part from too much serotonin in our entrails, and could perhaps be regarded as a “mental illness” of the second brain.

In a new Nature Medicine study published online February 7, a drug that inhibited the release of serotonin from the gut counteracted the bone-deteriorating disease osteoporosis in postmenopausal rodents. (Scientific American is part of Nature Publishing Group.) “It was totally unexpected that the gut would regulate bone mass to the extent that one could use this regulation to cure—at least in rodents—osteoporosis,” says Gerard Karsenty, lead author of the study and chair of the Department of Genetics and Development at Columbia University Medical Center.

Serotonin seeping from the second brain might even play some part in autism, the developmental disorder often first noticed in early childhood. Gershon has discovered that the same genes involved in synapse formation between neurons in the brain are involved in the alimentary synapse formation. “If these genes are affected in autism,” he says, “it could explain why so many kids with autism have GI motor abnormalities” in addition to elevated levels of gut-produced serotonin in their blood.
