Tests Help Predict Falls in Parkinson’s Disease

24.06.2010
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.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
