办公楼内时常会见到不少人眼睛盯着电脑,他们双手前伸在电脑键盘上,一坐就是好几小时基本不动,而且坐姿不正确。长此以往,这类人群中大多会出现手臂麻木、胳膊酸痛、上肢乏力,甚至于出现肌肉萎缩的症状,很多人以为这是颈椎病或者肩周炎等病症。中国工程院院士、复旦大学附属华山 Many people in the office often see a lot of people staring at the computer, their hands stretched out on the computer keyboard, sit for hours and hours, and the posture is not correct. Over time, most of these people will appear arm numbness, arm pain, upper limb fatigue, and even symptoms of muscle atrophy, many people think it is cervical spondylosis or frozen shoulder and other diseases.
