MS4 DYNAMOMETRY EXAM ACTUAL QUESTIONS AND

ANSWERS WITH COMPLETE SOLUTIONS VERIFIED


What 4 aspects of muscle function can be tested with dynamometry?

1. Strength

2. Power

3. Coordination

4. Endurance

Ability to generate high force

Strength

Ability to generate force rapidly (force over time)

Power

Ability to rapidly modulate force

Coordination

Ability to maintain muscle performance over time

Endurance

_________ may be the most important variable for older adults due to their

specific deficits

Power

-deficits in speed

What is the downside of using weightlifting for examination of muscle

performance? (ex: 1RM)

, You are limited by the muscle's weakest point in the ROM

-once you fail at the weakest point, you can't overload or examine muscle function at the

strongest point

How does force-velocity curve and length-tension curve make "gym" testing

difficult?

1. Changes in muscle length affects force production

2. Changes in force affects velocity (slow= more force)

What pt specific factors can make gym testing difficult? (3)

1) Pain

2) CNS impairments

3) Tone change

What is the gold standard for muscle testing?

-MMT

-Dynamometry

-1 Rep max

Dynamometry

-quantitative

It is difficult to assess torque production at different angles with "gym testing"

and MMTs (T/F)

True

You can extrapolate muscle length, based on joint angle (T/F)

False

-pennation angle, # of heads, joint motion, all make it more complicated
