Q

Manual Muscle Testing is used…

How is it used to aide

A

To determine the extent of muscular weakness as the result of disuse, injury or disease

Q

Examiners in manual muscle testing place the participant in…

A

A position and try to break the participant by moving them away from their isometric hold

They then grade muscle contraction based on MMT grading scale

Q

Patient positioning in Manual Muscle testing involves

A

Muscle is placed at optimum muscle length tension relationship

Exact position varies per muscle group

Patient is physically placed in position to best test that muscle group

Q

How could you modify the test for hip flexion using MMT if the patient cannot lift their own leg to optimal position

Q

Examiner positioning during MTT involves

A

Placing the resistance to maximise your mechanical advantage

In order to resist the patient isometrically, the amount of torque you apply must match the amount of torque the patient applies - static equilibrium

Muscle torque = resistance torque

Q

Goniometry exception is

Why

A

Q

Manual muscle testing (MMT) and dynamometry are most commonly performed using what type of muscle contraction

A

Isometric

29
Q

If a patient is only able to achieve full range of motion in a gravity eliminated position, they would score what on the MMT scale

A

2

30
Q

For MMT, you should place the participant in a position where the muscle is shortened and weaker relative to the optimum length-tension relationship

A

False

31
Q

What factor can you most easily manipulate in order to improve your mechanical advantage when resisting the patient

33
Q

Which portion of the goniometer do you line up with the joint center

A

35
Q

Measuring trunk flexion/extension range of motion is done by lining the goniometer axis with the hip joint, the stationary arm with the thigh, and the moving arm with the shoulders

A

False
