Data Test 5 - MMT

What is another name for dynamic testing?

Isotonic

Dynamic strength testing is....

Examples....

Testing a constant resistance

Examples - free weights or 1RM

What is another name for anterior surface?

Volar

Isokinetic strength testing is....

Examples....

Provide resistant through ROM @ a constant velocity

Examples - isokinetic dynamometer

Isometric strength testing is....

Examples....

Muscle generating force against an immovable resistance with muscle @ a fixed length

Examples - MMT or handheld dynamometry

Functional testing is....

Examples.....

designed to examine the capacity of synergistic muscle groups to generate force output adequate to complete a specific task

Examples - chair rise test

What is the purpose of MMT?

- Measure a muscle/muscle group ability to develop tension against resistance

- determine the extent and degree of muscular weakness from disease, injury, disuse

What is one problem with the 1RM test?

Patient will get fatigued through multiple attempts of 'finding' 1RM so is it really a true measurement of maximal strength?

What is the definition of manual muscle testing?

using hands and unaided visual observation to determine strength

How do you isolate muscles?

- If two joint muscle you put one on slack (like bending the knee during hip extension or sitting up to perform SLR)

- Put the muscle in direct line of pull

Why do we palpate the muscle during MMT?

- To look for activation

- Feel for substitutions

When do we palpate the muscle during MMT?

During AROM but not during active resistance

What is the purpose of the therapist performing PROM? 2 reasons

To establish TEST ROM and to demonstrate the required motion to the patient

What is the purpose of recommended positioning in MMT? 4 reasons

- ensure appropriate muscles are tested

- ensure motions are not restricted

- minimize substitutions

- optimize examiners body mechanics for a good test

Complete the sentence -

The proximal joint segment must be ...... in order for a ...... contraction to occur.

Stable, maximum

5

4

3

2

1

0

5 - Normal

4 - Good

3 - Fair

How is resistance applied during MMT?

Gradually and smoothly

Contrainidications for MMT?

- unhealed fx/surgery related to joint or motion being tested

- significant pain associated with testing

What can be said about the use of MMT vs HHD/ Isokinetic dynamometry?

MMT not as valid with higher grades of strength but more effective when detecting low levels of strength

Which three movements do we not stablilze with?

- Ankle PF

- Ankle DF

- Trunk Flexion

Where do you apply resistance during the break test?

Distal segment of the joint

In order to help consistency with MMT what should the therapist do?

Document whenever alternate positioning is used

Where do we stabilise?

Proximal joint segment

What are the 4 things we can do to help limit substitutions?

Positioning, Observing, Palpating, stablizing

What muscles perform shoulder IR?

Subscapularis, lats, teres major, pectoralis major

How do you isolate the brachioradialis?

Wrist in neutral (thumbs up)

How do you isolate the brachialis?

Pronate the forearm

How do you isolate the glute max with hip extension?

Bend the knees (straight legs puts more emphasis on HS)

How do you isolate (not fully isolate but make the primary mover) the biceps for forearm supination?

Bend the elbow to 90 degrees flexion

How do you make the supinator muscle the primary muscle for wrist supination?

Extend the elbow

Which two shoulder movements do not have a GE position?

Shoulder Abduction (scapular plane) THUMB up and down

Muscles for shoulder ABD (frontal) vs (scapular plane)

Frontal plane - mid delt, supraspinatus

Scapular plane - supraspinatus, mid delt

Same muscles but more emphasis on supraspinatus in scapular plane

ROM Shoulder ABD (scapular plane) Thumbs up vs down

Thumbs up - 180

Thumbs down - 120

When stabilising the superior ipsilateral shoulder during shoulder FLX and ABD, what is it important to be conscious of?
