Exercising At Home Has A Positive Effect On Parkinson's Patients
Even though exercise is known to be healthy, many people find it difficult to maintain an exercise program for a longer time. This applies even more to people with a chronic illness such as Parkinson's disease, where physical and mental limitations are additional obstacles. The Park-in-Shape study, funded by ZonMW (Netherlands Organization for Health Research & Development), tested an innovative solution for this challenge. The participants were divided into two groups. Both groups had a motivational app at their disposal, which offered the participants rewards for exercising. The control group only performed stretching exercises, while the active intervention group was instructed to exercise for 30-45 minutes on a stationary bicycle at home, at least three times a week.
The active group's exercise bikes were also equipped with motivating games, making the program more entertaining and

Exercising While Restricting Calories Could Be Bad For Bone Health
A new study published today in the Journal of Bone and Mineral Research shows how bones in mammals are negatively impacted by calorie restriction, and particularly by the combination of exercise and calorie restriction. Maya Styner, MD, associate professor of medicine at the UNC School of Medicine, is the senior author on the study.
“These findings were somewhat of a surprise for us,” Styner said. “Past studies in mice have shown us that exercise paired with a normal calorie diet, and even a high calorie diet, is good for bone health. Now we’re learning this isn’t true for exercise along with a calorie-restricted diet.”
Styner’s research focuses on the fat in bone marrow of mice. Although fat in the bone is poorly understood, to date it is thought to be harmful to bones of mammals, including humans, because it makes bone weaker. Less fat is usually an indication of better bone health.

Multicomponent Home-Based Treatments Improve Mobility In Older Adults After Hip Fracture
Each year more than 260,000 older Americans are hospitalized for hip fractures, a debilitating injury that can severely and permanently impact mobility. Researchers at the University of Maryland School of Medicine (UMSOM) studied two types of home-based interventions and discovered that these treatments are effective in helping individuals regain their ability to walk, but not enough to do every day functions like crossing the street.
Jay Magaziner, PhD, MSHyg, Professor and Chair of the Department of Epidemiology and Public Health at UMSOM was the Principal Investigator for this research and Rebecca L Craik, PT, PhD, FAPTA, Dean of the College of Health Sciences at Arcadia University was Co-Principal Investigator. The research was a multidisciplinary partnership involving investigators from epidemiology, physical therapy, geriatrics, orthopedics, gerontology, health economics, biostati

Feeling Legs Again Improves Amputees' Health
While walking, people with intact legs feel when they move their knee or when their feet touch the ground. The nervous system constantly draws on sensory feedback of this sort to precisely control muscles. People using a leg prosthesis, however, do not know precisely where the prosthesis is located, how it is moving, or what type of terrain it is standing on. They often cannot trust their pros-thesis completely when walking, leading them to rely too often on their intact leg, which in turn re-duces their mobility and causes them to tire quickly. A simple walk on pebbles or sand, for example, can prove very exhausting for people using a prosthesis. Furthermore, people with amputations can experience phantom limb pain, a condition that existing medications often cannot treat. Savo Panic, who experiences this phenomenon, says he wakes up at night due to the phantom pain: "The toe that I don
