I'm going to keep the questions coming. Can anyone tell me what a myometric movement is (ie. Myometric incline bench & myometric supinated chins)? Thanks |

My-oh-metric...the typical reaction of an American, who upon entering their first Olympic weightlifting meet, realizing that they have to give their attempts in kilograms.

You stumped me there, so I went looking for it. I never found a
clear definition that matched the usage you mention, but it's used in
studies of various neuromuscular pathologies. I did find this: In the study the myometric method
(Vain, 1997, 2000) was used. The essence of the method lies in
giving biological tissue a short mechanical impulse and acquiring the
mechanical response of the muscle by an acceleration probe. From the
acquired damped natural oscillation waveform the muscle stiffness,
oscillation frequency and logarithmic decrement of damping are
calculated. these quantitative parametersallow to estimate muscle elasticity (Vain et al., 2000).
I looked at a bunch of other abstracts that more or less indicated a similar intention: not a measurement of force, but of muscular elasticity. Perhaps a "myometric movement" involves passively measuring the response of the muscle in lifting (?). -Wayne ------------- "We may be small, but we're slow." - MIT Rugby |

Now I have seen everything. The genius stumped. ------------- Donate lately? |

Heh. <insert witty comeback> I have since learned that a myometer usually refers to a force gauge used in isometric muscle testing. In some cases, the tester holds the myometer while the patient attempts to pull or push as requested. In others, the myometer is a gripper with a digital readout. Thus, a myometric incline press or supine chinup appears to be an isometric force test where the patient pulls or pushes in the particular position. By the way, one of the themes you run into in the literature is a lot of questions about whether the numbers can be relied upon (or even compared, before and after, for a given patient). -Wayne ------------- "We may be small, but we're slow." - MIT Rugby |

| Thanks for checking around. Explain to me again what a myometric incline bench looks like. |

I suspect the patient sits in an inclined position and pushes upward
against an object (either held by a person or a fixed machine) that
measures the force. -Wayne ------------- "We may be small, but we're slow." - MIT Rugby |
