A robotic arm that can be worn at home is being developed to help stroke survivors regain the ability to reach and grasp objects and perform basic tasks such as feed themselves.
The device, built by a research team, led by biomedical engineer Jiping He, Ph.D., and his colleagues at Arizona State University and Kinetic Muscles, Inc., a start up biotech company, can also assess the effectiveness of the physical therapy so adjustments can be made to the regimen if necessary. He will present a paper on the robotic arm this summer at the 9th International Conference on Rehabilitation Robotics in Chicago.
Recent research suggests that stroke survivors can recover significant use of their arms by performing repetitive motor function exercises over a period of time. This labor intensive physical therapy is expensive, however, claiming up to 4 percent of the national health budget, according to the National Institutes of Health. Moreover, health insurers may limit or deny coverage before stroke survivors achieve best results, He said.
"This device is intended to provide cost-effective therapy to a wider population for a longer period of time for maximum recovery of motor function," He said of the device, dubbed RUPERT I, for Robotic Upper Extremity Repetitive Therapy.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
