WASHINGTON--The results of a new study from the Christopher & Dana Reeve Foundation show there are nearly 1 in 50 Americans living with paralysis, almost 40 percent higher than previous estimates. The study, which surveyed more than 33,000 households, also shows more than five times the number of people living with spinal cord injury than previously thought.
 
Specifically, the survey shows that 1.275 million have had a spinal cord injury and over 5.6 million Americans live with some form of paralysis. The highest previous estimates were 250,000 and roughly 4 million, respectively.
 
The study was conducted by the University of New Mexico's Center for Development and Disability. More than 30 experts from 14 leading universities and medical centers and the U.S. Centers for Disease Control and Prevention set the parameters for the survey. The development of the survey, acquisition and analysis of the data took over three years.
 
"This is the first population-based survey to measure the national prevalence of paralysis," said Anthony Cahill, Ph.D., principal investigator for the study and director of the Division of Disability and Health Policy at the University of New Mexico's School of Medicine. "The enormous data set offers a wealth of information about this population."
 
Major findings of the study show:
 
--Paralysis is dramatically more widespread than previously thought. Approximately 1.9 percent of the U.S. population, or 5,596,000 people, reported they were living with some form of paralysis, defined by the study as a central nervous system disorder resulting in difficulty or inability to move the upper or lower extremities. This is about 40 percent more Americans living with paralysis than previously estimated (~4 million).
 
--Spinal cord injury is also more prevalent than previously estimated. Data indicate that 1,275,000 people in the United States are living with spinal cord injury--more than five times the number of Americans previously estimated in 2008 (255,702).
 
--The leading cause of paralysis was stroke (29 percent), followed by spinal cord injury (23 percent) and multiple sclerosis (17 percent).
 
--Paralysis appears to be disproportionately distributed among some minority communities such as African Americans and Native Americans, but not all. Hispanics who are living with paralysis represent approximately the same percentage as those who report being Hispanic in the U.S. census.
 
--Household income for those with paralysis is heavily skewed towards lower-income brackets and is significantly lower than household income for the country as a whole. Roughly 25 percent of households with a person who is paralyzed earn less than $10,000 per year, compared with only 7 percent of households in the general population.
 
According to Dr. Edwin Trevathan, director of the CDC's National Center on Birth Defects and Developmental Disabilities, the study is a “crucial first step to providing appropriate public health supports for this community in understanding how many people live with the condition, who they are, and what they need.”
 
"The health care system is often penny-wise and pound-foolish," added the Reeve Foundation’s Joseph Canose, who directed the project. "For example, many health insurance companies will not pay for a $400 wheelchair seat cushion, but they will pay $75,000 to $100,000 to treat the pressure sores caused by the wrong cushion. The more we can do to help people live independently--to get an education, to work and to live fulfilling lives--the more our entire society benefits."

Last month, President Obama signed the Christopher and Dana Reeve Paralysis Act into law. The legislation promotes collaborative research, rehabilitation and quality-of-life initiatives for Americans living with paralysis and spinal cord injuries.
