Deck 24: Evaluation of Muscle Strength

Question 1

MMT would never be appropriate for a client with which of the following conditions?

A) Peripheral nerve injury
B) Spastic cerebral palsy
C) Muscular dystrophy
D) Spinal cord injury
E) Multiple sclerosis

Answer 1

B
MMT is not appropriate for and cannot be used accurately with clients having spasticity caused by upper motor neuron disorders such as stroke or cerebral palsy because muscles are often hypertonic and clients are unable to isolate joint motions.

Question 2

What is the best way to eliminate substitutions during MMT?

A) To perform the test in several different positions
B) To refrain from stabilizing so the client can move more freely
C) To observe the motion
D) To palpate contractile tissues
E) To allow extraneous motion

Answer 2

D
It is only through correct palpation that the therapist can be certain that the motion observed is not being performed by substitution of another muscle or muscle group.Correct positioning,stabilization,and avoidance of extraneous motion minimize substitutions.

Question 3

Which of the following statements is true about a muscle with a number grade of 3+?

A) Part moves through less than 50% of available ROM.
B) Part can move against gravity.
C) Part cannot take resistance.
D) Part can take maximal resistance.
E) Part can take moderate resistance.

Answer 3

B
A 3+ muscle moves through complete ROM against gravity and takes slight resistance.Therefore the other answers are incorrect.

Question 4

Which of the following is true about MMT?

A) It can measure muscle endurance.
B) It cannot help determine if a nerve injury is partial or complete.
C) It can measure muscle coordination.
D) It cannot be used to identify muscle imbalance.
E) It can help determine the level of spinal cord injury.

Question 5

The amount of resistance applied to a muscle should not depend on which of the following?

A) The cross-sectional size of the muscle
B) The age of the client
C) The relative power of the muscle
D) The gender of the client
E) The strength of the therapist

Question 6

Which of the following is not a criterion used to measure strength in MMT?

A) Amount of motion through which the joint moves when the muscle contracts
B) Evidence of muscle contraction
C) Endurance of muscle
D) Amount of resistance against which the muscle can contract
E) A and C

Question 7

Which of the following is not a contraindication for MMT?

A) Joint hypermobility
B) Joint dislocation
C) Unhealed fracture
D) Bone carcinoma
E) Recent musculoskeletal surgery

Question 8

MMT accuracy can be negatively influenced by which of the following?

A) Placing the client on a comfortable soft surface
B) Repeating the test several times on the body part
C) Positioning the body part correctly
D) Palpating muscles before applying resistance
E) A and B

Question 9

In what plane is the MMT for grades F- and higher performed?

A) Horizontal plane
B) Gravity-minimized plane
C) Vertical plane
D) Gravity-assisted plane
E) Gravity-eliminated plane

Question 10

Which of the following is the correct order of steps for MMT of muscles grades 3 and higher?

A) Palpate, stabilize, position, resist, observe
B) Position, stabilize, palpate, observe, resist
C) Stabilize, position, palpate, observe, resist
D) Position, palpate, stabilize, observe, resist
E) Stabilize, position, observe, resist, palpate

Question 11

Which of the following is not considered a screening test for muscle strength?

A) Reviewing the medical record for previous strength assessments
B) Observing the client perform a functional activity
C) Observing the client move around the clinic
D) Performing a manual muscle test (MMT)
E) Performing a gross check of muscle group

Question 12

If a muscle contraction can be seen or felt but no motion is observed,the grade is ____________________.

A) 0
B) 1-
C) 1
D) 1+
E) 2-

Question 13

A part that moves through incomplete motion with gravity minimized would be graded ____________________.

A) Poor plus
B) Poor
C) Poor minus
D) Fair plus
E) Fair minus

Question 14

Which of the following does not belong with the others?

A) Good
B) Normal
C) 4
D) Moderate resistance
E) B and D

Question 15

During the MMT,when should resistance be applied?

A) Before motion begins
B) Midway through motion
C) Throughout entire motion
D) At end of motion
E) With maximum force
