Test 1.3

Question 1

Why does muscle strength allow for and what factors affect strength

Answer 1

It allows for ability to resist or produce force by a muscle

Factors

• muscle angle of pull
• angle of resistance
• muscle length
• speed of contraction

Question 2

What are the method of assessment for muscle strength

Answer 2

• free weights (weakest point in ROM)
• weight machine
• isokinetics
• dynamometers
• electromyography
• MMT

Question 3

True or false

EMG can determine muscle strength

Answer 3

False

Question 4

What are issues with isokinetics

Answer 4

Poor stabilization
High cost
Set up is timely

Question 5

What are some characteristics of MMT

Answer 5

• used to assess strength of a muscle
• can be performed isometrically or isotonically
• used during assessment

Question 6

What are the characteristic of manual resistance exercise

Answer 6

• used to increase strength of a muscle
• can be performed isometrically or isotonically
• used during rehab

Question 7

What are the basic rules of MMT

Answer 7

• stabilize proximal segment
• place joint in antigravity position
• apply pressure opposite side
• apply pressure gradually
• use a long level when possible

Question 8

What are the types of MMT

Answer 8

Break test(hold for 5 secs)

MMT through full ROM (test for 5 reps)

Question 9

What should patient do during testing

Answer 9

• should be against gravity
• should keep other body parts stable
• be comfort

Question 10

What is the order of testing for the patient

Answer 10

Supine
Side-lying
Prone
Seated 
Standing

Question 11

What is fixation influenced by

Answer 11

• examining table
• body weight
• examiner
• muscles

Question 12

What range should you go to if you test one or two joint muscles

Answer 12

One joint muscle - end range

Two joint muscle- midrange

Question 13

What are the advantages of proper test position

Answer 13

• detection of muscle substitution

- AIDS in grading

Question 14

What is resistance

Answer 14

Force hat hinders motion applied by examiner or gravity

Question 15

What is substitution

Answer 15

Muscle or muscle groups attempt to compensate for a weak muscle
