WASHINGTON Nike Air Max Plus Men's Gradient Pack Yellow Blue , July 26 (Xinhua) -- U.S. researchers have created a lightweight, soft robotic ankle support that could help stroke patients walk more easily, according to a study published Wednesday.
"In about 80 percent of patients post-stroke, it is typical that one limb loses its ability to function normally -- a clinical phenomenon called hemiparesis," said the study published in the U.S. journal Science Translational Medicine.
"And even patients who recover walking mobility during rehabilitation retain abnormalities in their gait that hinder them from participating in many activities Nike Air Max Plus Sunset Black Blue Men's , pose risks of falls, and, because they impose a more sedentary lifestyle, can lead to secondary health problems," it said.
To help stroke patients regain their walking abilities Nike Air Max DLX 2019 Sale , various robotics groups from industry and academia are developing powered wearable devices known as exoskeletons, but most of which are rigid, bulky products that are impractical for people to wear during everyday activities.
In search of a better alternative, researchers at Harvard University's Wyss Institute for Biologically Inspired Engineering and Boston University's College of Health & Rehabilitation Sciences developed a soft robotic ankle-support system weighing 0.9 kg, roughly twice as heavy as a soccer ball Nike Air Max DLX Sale , to be worn on one side of the body.
Their system consists of a close-fitting waist belt and leg straps connected to a calf sleeve where small robotic actuators exerted force on a shoe insole to provide forward propulsion and correct problems with ankle dorsiflexion, commonly referred to as "drop foot," which affects roughly 20 percent of stroke survivors.
Over two days of testing, nine subjects ranging from 30 to 67 years old who were undergoing rehabilitation after strokes all showed more efficient and less asymmetrical strides when wearing the device, both when walking on a treadmill in the lab and over ground in a real-world environment.
What's more Nike Air Max Plus 97 Sale , the researchers observed the most pronounced improvements among the individuals who had the slowest unassisted walking speeds.
The team was now looking to further personalize its system to specific gait abnormalities, investigate assistance at other joints such as the hip and knee, and assess longer-term therapeutic effects of their technology.
"This study provides a glimpse of a new future where much of patient care will be carried out at home with the help of human-friendly robots, which look nothing like the robots we see in television and movies," Wyss Institute Founding Director Donald Ingber Nike Air VaporMax Plus Mens Sale , who was not involved in the study, said in a statement.
"This exosuit looks more like sports clothing than R2D2, yet it is equally programmable and carries out tasks on command; however, the exosuit is lightweight, flexible Nike Air VaporMax Plus Womens Sale , virtually invisible to others, and individualizes itself for each patient. We hope that it will soon enter clinical use where it undoubtedly could transform the lives of stroke patients for the better," Ingber said.

BEIJING, Jan. 18 (Xinhua) -- China's health authority saidThursday that about 51 percent of China's newborn babies in 2017were second children in the family, a 5 percentage points increasefrom 2016.
China's National Bureau of Statistics estimated that there were17.23 million babies born in 2017. Numbers collected from hospitalsshowed there are 17.58 million newborns Nike Air VaporMax Plus Sale , according to a statementon the website of the National Health and Family PlanningCommission (NHFPC).
Figures provided by the NHFPC earlier showed that 18.5 millionbabies were born in hospital in 2016, the highest since 2000.
Surveys show that financial, career and childcare concerns aremain reasons that families are hesitant to have a second child.
In response to an aging population, since 2016 couples have beenallowed to have two children. Enditem
WELLINGTON, March 10 (Xinhua) -- Police and food safety officials asked for the public's help Tuesday in finding the person or people behind the threat to poison New Zealand infant formula.
Political and industry leaders from across the country united in condemning the threat in anonymous letters sent to farming and dairy industry leaders in November last year.
Prime Minister John Key said in a televised press conference that the government had planned to reveal the threat next week Nike Air Max Plus TN Ultra Sale , but moved earlier after news media began asking questions.
He defended the delay in warning the public, saying food safety officials and the industry had to first ensure the entire supply chain was secure against any threat, while the police needed time to conduct a thorough investigation.
"We're advised it is extremely unlikely anyone could deliberately contaminate formula during the manufacturing process and there is no evidence that this has ever occurred," said Key.
"My message to New Zealanders, and parents in particular Nike Air Max Plus TN Womens Sale , today is that while it is very likely this threat is a hoax, we as the government have to take it seriously and I can assure you that we are."
The police had earlier urged the person or group responsible for the threat to come forward.
"The letter writer may not have really considered the implications of their actions when this communication was drafted. Now is the time to put this right by picking up the phone and calling us," Deputy Commissioner (National Operations) Mike Clement said in a statement.
