五大健康误区：你曾相信过吗？

If you thought you had to stretch before and after exercise to prevent injury, then you wouldn't be alone. But this is just one of a number of common practices that actually don't do anything beneficial for your health. The top five physiotherapy myths have been publicly busted by the world's largest physiotherapy clinical research website. Surprisingly what are commonly known as effective practises, are actually misconceptions and have no hard evidence to back them up.

你不是唯一一个认为运动前需要先拉伸的人，然而实际上有很多常见的练习并不会对你的健康有益。近期，世界最大的物理疗法网站近期公布了五个最常见的误区。出人意料的是，人们普遍认为有效地措施实则缺少理论支持，属于认识误区。

1.The type of mattress you sleep on prevents back pain

1.床垫的种类可以预防背痛

'This is a surprising one. We did thorough research of the physiotherapy database, including the best quality research done and we couldn't find any well conducted trials to evaluate this,' said PEDro manager Anne Moseley.

“这一点很令人惊讶。我们对理疗数据库进行了详细的调查，包括最高质量的研究，然而并没有找到能验证这点的说法。”网站经理安妮·莫斯利说道。

2.Stretching prevents injury and muscle soreness in recreational runners

2.拉伸可以帮助跑步锻炼的人减少受伤或肌肉酸痛

Really well conducted research shows stretching before and after a run makes no difference to injuries and muscle soreness. There is high quality research that there are other things you can do - agility training, co-ordination training, active warm ups, exercise related to the sport.

详细的调查表明跑步前后拉伸都会受伤或肌肉酸痛没有任何影响。一项高质量调查表明，有其他办法可供参考，即与该项运动相关的敏捷性训练，协调性训练及热身练习。

3.You should wear a neck brace if you have a whiplash neck injury

3.脖颈受伤时应戴颈托

Just like Aussie model Miranda Kerr who was recently seen wearing a neck brace after a car accident she had in Los Angeles, people often believe this is the way to heal their body quicker, but in fact that's not the case.

澳洲模特米拉达·可儿最近在洛杉矶出车祸后戴着颈托出现，和她一样，人们认为颈托可以辅助身体愈合。然而事实并非如此。

Anne Mosley says for those who suffer spinal fractures at accidents, it is completely necessary, but if there is no fracture and just whiplash, research has found that wearing a brace is detrimental. 'The best treatments are to stay active and use graded activity, to increase the amount of activity.

安妮·莫斯利解释道，如果事故造成了脊柱骨折，那么颈托很有必要，但是如果没有骨折仅仅是扭伤的话，戴颈托反而有害。“最佳治疗方式是保持颈部活动，循序渐进增加活动量。”

4. Ultrasound for the recovery of ankle sprains

4.超声波治疗脚踝扭伤

5. An incentive spirometer - a device which patients use to help them take deep breaths to prevent complications during upper abdominalsurgery or cardiac surgery

5.诱导性肺量器:在上腹部手术或心脏外科手术中使用，使患者深呼吸来防止并发症出现

These are based on the use of gadgets that people have to pay for, which can sometimes be expensive. 'Research shows an incentive spirometer doesn't change complication rates.' Ms Moseley says most of these findings will be interesting to Australians and some will debate what have been labelled myths. 'We really value the physiotherapist database, it provides high level evidence to support these claims and having treatment guided by research is a great way to make decision about health care.'

这两项针对的都是付费（通常并不便宜）的工具。“调查表明诱导性肺量器并不能降低并发症几率。”莫斯利女士说这些发现将在澳大利亚人民中引起热议。“我们认为理疗数据库提供了非常宝贵的资料，它使我们健康护理更有依据性。”
