肌力测定的种类?如何测定?

答案

参考答案:

(1)徒手肌力测定(ManualMuscleTest,MMT):可对每个关节,每块肌肉或参与肌群主动动作肌及辅助肌的肌力进行测定。适.用于末梢性弛缓和废退性肌无力,对中枢性瘫痪不适宜。

肌力测定分为6级:①零(Zero,0),0级(0%):肌肉完全无收缩;②差(Trace,T),1级(10%):可以看到或触知肌肉变紧,即有肌肉的轻微收缩,但关节无运动;③可(Poor,P),2级(25%);排除重力(肢体重力)后可完全运动者;④良(Fair,F),3级(50%):只能克服重力而完成运动,但不能对抗阻力进行活动;⑤优(Good,G),4级(75%):能克服重力及一定的抵抗力而完成运动;⑥正常,(Normal,N),5级(100%):能克服重力及最大的抵抗力而完成运动。

(2)肌力功能试验(MotorFunctionTest,MFT);适用于中枢性运动麻痹,肌力低下者,由于以下原因(除轻度麻痹外,不能以MMT、评价)对不能进行单关节运动,只能进行如上肢数个关节联合运动的协调运动,虽尚有一定肌力,但运动徐缓,非属正常模式;因姿势不同,有时能运动或不能运动,无恒定性,等等。MFT测定常用于偏瘫病人和大脑性瘫痪病人。有简易的MFT(6级法,Brannstrom偏瘫功能试验)和标准MFT(12级法)。

(3)简单器械的肌力测试:有握力测试、捏力测试、背力测试等。

(4)等速肌力测试:常用有Cybex、Biodex、Kincon、Lido、Ariel等仪器。等速肌力测试,肌力要在三级以上。

Sadness isn’t manly—this Eric Weaver knew. When depression engulfed this New York police sergeant, it took a different guise: a near-constant state of anger. "One minute I’d be okay and the next minute I’d be screaming at my kids and punching the wall," he recalls. "My kids would ask, ’What’s wrong with Daddy Why’s he so mad all the time’" For years, Weaver didn’t know what was wrong.

Weaver’s confusion about what tortured him was not unusual. Roughly a third of the 18 million or more Americans who suffer depression each year are men. Yet all too often, experts say, men fail to recognize the symptoms and get the treatment they need.

For years, experts suspected that gender makes a big difference in depression. Studies from New York to New Zealand have repeatedly found the same startling statistic: About twice as many women as men suffer from depression. That finding was considered one of the bedrock facts of modern mental health. Yet it has recently come under attack from critics who are concerned about underreporting of male depression.

William Pollack, Director of the Center for Men at McLean Hospital, is leading the charge against the well-entrenched depression gender gap. He argues that men’s rate of depression may be nearly equal to women’s. Just look at suicide rates, he says: Male suicides outnumber females four to one. That ratio "is way too high to say that men’s depression numbers are so low," he notes.

Pollack and others contend that male depression goes unrecognized because, unlike the female version, it often doesn’t fit the textbook signs—at least in the early stages. Clinical depression at later stages looks much the same in both sexes. But in the prelude to a breakdown, that deepening despair is often expressed in very different ways. Instead of being weepy, men are more apt to be irritable and angry—moods that aren’t included in the classic diagnostic tests. "Their sadness and helplessness are hidden behind a mask of anger," says Pollack.

"Men tend to act out" to avoid dealing with uncomfortable feelings, adds Fredric Rabinowitz, a psychologist who works primarily with men. If they feel bad, they’re apt to get into fights on the job or at home, withdraw from family and friends, become obsessed with work or hobbies. Most significantly, men often turn to drinking or drugs. Men have two to four times the rate of substance abuse problems as women, and Pollack contends that if this was recognized as a sign of depression, the gender gap would substantially narrow.

Which of the following is true according to the first two paragraphs()

A. Mr. Weaver considered anger was a guise of depression

B. Depression may result in similar symptoms

C. Men generally ignore the signs of depression and its treatment

D. One third of male Americans suffer depression each year
