Spinal cord injury specialist says 60 percent of his patients are obese

As Americans face a growing epidemic of obesity, people with spinal cord
injuries find themselves particularly vulnerable to the serious
complications that come with carrying around extra pounds.
About 60 percent of the spinal cord injury patients seen by David Gater,
M.D., Ph.D., director of spinal cord injury medicine at the University of
Michigan Health System and the VA Ann Arbor Healthcare System, are obese –
double the national rate of obesity among the general population. Paralysis
caused by the injury leads to significantly less muscle mass, so these
patients burn fewer calories, even at rest. In addition, they’re unable to
exercise the largest muscles – the buttocks, thighs and hamstrings –
limiting their ability to build muscle mass.

Gater’s research team has begun several new studies to look at how people
with spinal cord injury burn calories, why their energy expenditure is
different and how to deal with the disproportionate rate of obesity among
these patients.

To showcase the accessible exercise equipment and tests designed to assess
the fitness of people with spinal cord injury, Gater’s lab will host an
open house from 11 a.m. to 3 p.m. Friday, Sept. 17 at the Ann Arbor VA
Healthcare System.

“Many of my patients with spinal cord injury would be able to exercise and
are highly motivated to exercise and take care of themselves, but they face
significant barriers. Their physiology makes exercise more difficult, and
physical access to gyms or equipment is an issue,” Gater says.

Gater’s lab includes a wheelchair ergometer that allows a person to propel
a wheelchair over rollers, weight machines with wheelchair access,
equipment to measure oxygen consumption which determines how many calories
a person burns, an underwater weighing tank and a special capsule that more
accurately measures body fat on a person with spinal cord injury.

“Standard measures of body composition don’t take into account the
decreased muscle mass, bone mass and body water that people with spinal
cord injuries have, so it’s difficult to assess accurately without special
techniques,” Gater says.

In addition, people with spinal cord injuries do not burn calories as
effectively as people without paralysis. Their heart rate is not as
responsive to the increased exertion, blood pools in their legs reducing
blood flow back to the heart, blood pressure is reduced, and the chest
muscles don’t expand as efficiently, making breathing difficult.

Spinal cord injury specialists use wraps on the legs and abdominal binders
to help increase exercise tolerance, and Gater’s work will help determine
how many calories patients burn when performing various activities, from
rolling their wheelchair to playing basketball.

Obesity increases a person’s risk of diabetes, heart disease and
osteoarthritis, and this is true of people with spinal cord injuries as
well. More than half of people who have lived at least 10 years with a
spinal cord injury develop diabetes or pre-diabetes, and increased body
weight significantly impairs their mobility and stresses their upper
extremities. Exercise can help prevent or delay these effects.

“In a lot of ways, spinal cord injury represents an accelerated version of
aging, as patients tend to develop these conditions at an earlier age than
the general population,” Gater says.
