Specially Designed Video Game Might Ease 'Phantom Limb' Pain

Posted 6 days ago by Drugs.com

THURSDAY, Dec. 1, 2016 – Amputees who experience what is known as phantom limb pain may benefit from playing a virtual reality game that simulates the movement of missing limbs, a small study suggests. "Phantom limb pain is a difficult condition to treat that can seriously hinder patients' quality of life," said study lead author Max Ortiz Catalan. He is an assistant professor at Sweden's Chalmers University of Technology. Phantom limb pain occurs when amputees feel painful sensations that appear to be coming from limbs that no longer exist. In about one-third of cases, the pain can lead to poor mental health and worsening disability, the study authors noted. "The results from our study suggest that it may be useful to 'exercise' the phantom limb," Catalan explained. "Our treatment offers an engaging way to do this while also providing a non-invasive and non-pharmacological treatment, ... Read more

Nerve Stimulation Restored Sense of Touch to Arm Amputees

Posted 26 Oct 2016 by Drugs.com

WEDNESDAY, Oct. 26, 2016 – Direct stimulation of the nervous system produced realistic sensations of touch in two arm amputees, researchers report. Both men lost their arms after traumatic injuries. They received implanted devices containing electrodes that were attached to the nerves of the arm. These nerves would normally carry signals to and from the hand. "If you want to create a dexterous hand for use in an amputee or a quadriplegic patient, you need to not only be able to move it, but have sensory feedback from it," said researcher Sliman Bensmaia. He's a neuroscientist and associate professor of organismal biology and anatomy at the University of Chicago. "To do this, we first need to look at how the intact hand and the intact nervous system encodes this information, and then, to the extent that we can, try to mimic that in a neuroprosthesis [a device that supplants or ...

Case Study Links New Neurological Complication to Zika

Posted 31 Aug 2016 by Drugs.com

TUESDAY, Aug. 30, 2016 – While news reports about Zika have mainly focused on how the virus affects developing fetuses, researchers have identified an adult man with a previously unreported neurological problem tied to the virus. The Zika virus has already been linked to a birth defect called microcephaly, in which a baby has an underdeveloped head and brain, and Guillain-Barre syndrome. Guillain-Barre can cause weakness and paralysis of the legs, arms, face and breathing muscles. In the new case study, researchers reported on a 62-year-old man from Honduras who was infected with Zika while traveling in Venezuela. The man developed problems with his sensory nerves while the infection was active. His condition, called sensory polyneuropathy, took several months to improve. People who experience this condition have a decreased ability to move or feel (sensation) because of nerve damage. ... Read more

Study: Causes of Gulf War Illness Pinpointed

Posted 2 Feb 2016 by Drugs.com

MONDAY, Feb. 1, 2016 – Exposure to pesticides and other toxins appears to be the cause of Gulf War illness in U.S. veterans, a new analysis states. The Boston University researchers reviewed studies on Gulf War illness, and said their findings "clearly and consistently" show a link between the disorder and exposure to pesticides and taking pyridostigmine bromide (PB) pills, which were meant to protect troops against the effects of nerve gas. There's also evidence of a connection between Gulf War illness and exposure to the nerve gas agents sarin and cyclosarin, and to oil well fire emissions, according to the findings published in the January issue of the journal Cortex. These toxins damaged troops' nervous and immune systems, and reduced the amount of white and gray matter in veterans' brains, said study leader Roberta White in a news release from the university. White is a professor ... Read more

Paralyzed Man Walks Using Technology That Bypasses Spinal Cord

Posted 24 Sep 2015 by Drugs.com

THURSDAY, Sept. 24, 2015 – A paralyzed 26-year-old man has walked for the first time in five years, thanks to an electrical system that connects his brain and legs, bypassing his injured spine, researchers are reporting. The unidentified man is the first person to show that a system like this might help people with a spinal cord injury regain some ability to walk, the researchers said. "The work does offer exciting promise," said Randy Trumbower, an assistant professor in the department of rehabilitation medicine at Emory University School of Medicine in Atlanta, who was not involved with the research. That said, it "must overcome several hurdles before it may be applicable to a broad population of persons with spinal cord injury," he added. Study authors An Do and Zoran Nenadic, both at the University of California, Irvine, said they don't yet know how the system will work in a larger ... Read more
