Flashcards in 05-10a: Manual Muscle Testing Deck (17):
1

Purpose of MMT

- Gather "objective" data for treatment planning and assessment of effectiveness of treatment
- Infomation regarding muscle strength of 1) specific muscles or 2) groups of muscles

2

Reliability and objectivity of MMT

- Not as reliable, valid and objective as other PT testing procedures
- Individual interpretation of the resistance we applied and the muscle's response

3

Numerical grading scales

- Without + and -
- With + and - (less objective, increases variability)

4

Qualitative grading scales

- Uses words and grade names
- Normal, Good, Fair, Poor, Trace, Zero

5

Normal (5)

- Full ROM AG, maximum resistance

6

Good (4)

- Full ROM AG, moderate resistance
- (4+) Full ROM AG, near max resist
- (4-) Fill ROM AG, less than mod resist

7

Fair (3)

- Full ROM AG, cannot hold against resistance
- (3+) Full ROM AG, Withstand min resist
- (3-) Less than Full ROM AG (more than 50%)

8

Poor (2)

- Full ROM GM, no resistance
- (2+) Full ROM GM, min resist or less than full ROM (less than 50%) AG
- (2-) Less than Full ROM GM

9

Trace (1)

- Unable to move through ROM, palpable contraction

10

Zero (0)

No muscle contraction

11

Types of MMT (3)

- Resistance provided through full ROM
- Resistance provided at mid-range (or specified test postition) after full ROM performed (break test)
- Resistance using hand-held dynamometer: may be done as a "make" or "break" test

12

MMT Procedure

- Begin with pt perform AROM of movement AG
- If complete full ROM, resist 1) through full ROM and grade, or 2) at test position an grade
- If cannot perform against resist, grade at least 3
- If cannot perform AG, less than 3
- Perform AROM in GM
- If perform AROM in GM, then grade 2
- If cannot perform full AROM in GM, palpate contraction for grade 1

13

Against Gravity (AG)

- Gravity is part of the resistance
- Grades 3-5: Body party performs ROM AG
- Perpendicular to floor

14

Gravity Minimized (GM)

- Grades 2 or lower
- Body part moves parallel to the floor
- Support body part to minimize friction

15

Grades 0-1

- Palpate muscle belly to determine muscle contraction
- Grade 1:Visible or palpable muscle contraction
- Grade 0: No contraction visible or palpable

16

Documentation

- Body part/muscle or motion tested
- Grade of MMT
- Pt response (if needed): pain, tenderness
- End-feel if unusual noted,
- Non-standard testing position

Need to know...

- Muscle location
- Muscle O, I, A, N
- Direction of muscle fibers, line of pull
- Substitutions
- Full AROM
- Stabilize proximal segment of joint being tested
- Muscle can fatigue
- No short cuts with MMT
