Tests Help Predict Falls in Parkinson’s Disease

A group of tests may help predict which people with Parkinson’s disease are more likely to fall, according to a study published in the June 23, 2010, online issue of Neurology®, the medical journal of the American Academy of Neurology.

“Falls are a major problem for people with Parkinson’s disease and can lead to injuries and reduced mobility, which can result in increasing weakness, loss of independence and increased use of nursing homes,” said study author Graham K. Kerr, PhD, of Queensland University of Technology in Brisbane, Australia. “Despite these issues and their impact on the health care system and society, little research has been done to help predict which people with Parkinson’s disease are more likely to fall so we can try to prevent these falls.”

For the study, 101 people with Parkinson’s disease who were able to walk without any aids took a variety of tests evaluating their Parkinson’s symptoms, balance and mobility. The participants then reported any falls that occurred over a six-month period.

Most participants were in the early stage of the disease, with an average of six years since the disease was diagnosed. The majority of the participants (77 percent) had the type of Parkinson’s that is mainly affected by difficulty with voluntary movements, while 20 percent had tremors as the central symptom of the disease.

A total of 48 percent of the participants had a fall during the study and 24 percent had more than one fall. A total of 42 percent reported that they had fallen in the year before the study started.

The tests that were the best predictors of whether a person was likely to fall included a test of overall Parkinson’s symptoms, a questionnaire on how often people tended to “freeze” while walking, and a test of balance. When these tests were combined, the results produced a sensitivity of 78 percent and a specificity of 84 percent for predicting falls. Sensitivity is the percentage of actual positives that are correctly identified as positive, and specificity is the percentage of negatives that are correctly identified.

“These tests are easy to implement and take only a short time to complete,” Kerr said. “Once we can identify those at risk of falling, we can take steps to try to prevent these falls.” In the United States, it is estimated that about one million people have Parkinson’s disease.

The study was supported by Parkinson’s Queensland Inc., the Queensland University of Technology, and the Australian National Health and Medical Research Council.

The American Academy of Neurology, an association of more than 22,000 neurologists and neuroscience professAmerican Academy of Neurologyionals, is dedicated to promoting the highest quality patient-centered neurologic care. A neurologist is a doctor with specialized training in diagnosing, treating and managing disorders of the brain and nervous system such as stroke, Alzheimer’s disease, epilepsy, Parkinson’s disease, and multiple sclerosis.

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
