A few years ago data indicated that 6.5% of Americans had reported ever using acupuncture. Of these, 22% had seen an acupuncturist in the last 12 months. 25% of those who had tried acupuncture had done so once, and 70% had seen an acupuncturist fewer than 5 times. The vast majority of those who had seen an acupuncturist had done so for some kind of pain, primarily arthritis and other orthopedic pain, headaches, or fibromyalgia. About 40% of the people who reported using acupuncture for a specific condition specifically reported not using conventional therapies for that condition , while 20-40% reported using some kind of conventional medical therapy for the same condition. 1- had done so ___had tried accupuncture_____ 2- those ______who had seen an acupuncturist____ 3- that condition __a specific condition____
Our data suggest that a major objective of weight- loss therapy in older adults may be to improve physical function, and we speculate that doing so may be at least as important as treating obesity-associated medical complications, which is often the main goal in treating obese younger adults.…
TASK 1 - Read the text and choose the correct alternative to make the sentences that follow the text true. SMART FABRICS MAKE CLEVER (MEDICAL) CLOTHING European researchers have developed a smart fabric that can monitor muscular overload and help prevent repetitive strain injury, or RSI. But that is just the beginning. The team is also exploring a pregnancy belt to monitor a baby’s heartbeat, clothing to help coach hockey, and shirts that monitor muscle fatigue during training. Smart fabrics promise to revolutionize clothing by incorporating sensors into cloth for health, lifestyle, and business applications. In the long term, they could consist of circuits and sensors that provide all of the typical electronics we carry around today, like mobile phones and PDAs. Current, first-generation applications are far more modest, and pioneering medical smart fabrics are used to monitor vital signs like heart rate and temperature. But two crucial hurdles - unobtrusiveness and reliability – impede widespread adoption of such clever clothes. Now one European research team has developed groundbreaking medical-sensing smart fabrics, and its work could lead to pregnancy monitoring belts, sports clothing that provides training tips, a wearable physical game controller, and a vest that helps to prevent repetitive strain injury. The Context project initially sought to develop an RSI vest to tackle a serious work safety issue. Repetitive actions can, over time, lead to permanent injury and the problem costs billions of euros a year. It affects over 40 million workers across the continent and is responsible for 50 per cent of all work-related ill- health. Muscle contraction, the very quiet metric The team had to tackle three challenging problems. First, they were using a relatively novel sensor that demanded sophisticated electronics located in the clothing. Second, they were aiming to measure muscle contraction, a very ‘quiet metric’. Third, they were venturing on a research path seldom trodden : muscle contraction as a predictor for stress. Long-term, low-key stress is the leading factor for RSI. ‘Each of the issues was very difficult. We chose to use a capacitative sensor because it does not need to be attached to the skin like resistive sensors do, which adds to the comfort. It needs controlling electronics close to the sensor to work effectively, and that presents a real challenge for textile integration,’ explains Bas Feddes, Context’s co-ordinator. Similarly, measuring electromyography, or electrical activity in the muscle, is more subtle and tricky than electrocardiography, which measures the heart. The rustle of clothing caused by movement can drown the signal. Context has gone a long way to solving that problem, but it is not as robust as they would like. Finally, medical understanding of muscle stress as a predictor for RSI is not a mature field of research, so it is difficult to say with certainty that specific activities could lead to RSI. Despite these hurdles, the team successfully designed an RSI vest, and they are currently improving its reliability. Context’s ambitious programme tackled pioneering and very complex issues in smart-fabric research, which resulted in a useful, unobtrusive, and reliable RSI vest that can warm wearers to take a recuperative break.
