05-10a: Manual Muscle Testing Flashcards
1
Q
Purpose of MMT
A
- 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
Q
Reliability and objectivity of MMT
A
- Not as reliable, valid and objective as other PT testing procedures
- Individual interpretation of the resistance we applied and the muscle’s response
3
Q
Numerical grading scales
A
- Without + and -
- With + and - (less objective, increases variability)
4
Q
Qualitative grading scales
A
- Uses words and grade names
- Normal, Good, Fair, Poor, Trace, Zero
5
Q
Normal (5)
A
- Full ROM AG, maximum resistance
6
Q
Good (4)
A
- Full ROM AG, moderate resistance
- (4+) Full ROM AG, near max resist
- (4-) Fill ROM AG, less than mod resist
7
Q
Fair (3)
A
- Full ROM AG, cannot hold against resistance
- (3+) Full ROM AG, Withstand min resist
- (3-) Less than Full ROM AG (more than 50%)
8
Q
Poor (2)
A
- 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
Q
Trace (1)
A
- Unable to move through ROM, palpable contraction
10
Q
Zero (0)
A
No muscle contraction
11
Q
Types of MMT (3)
A
- 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
Q
MMT Procedure
A
- 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
Q
Against Gravity (AG)
A
- Gravity is part of the resistance
- Grades 3-5: Body party performs ROM AG
- Perpendicular to floor
14
Q
Gravity Minimized (GM)
A
- Grades 2 or lower
- Body part moves parallel to the floor
- Support body part to minimize friction
15
Q
Grades 0-1
A
- Palpate muscle belly to determine muscle contraction
- Grade 1:Visible or palpable muscle contraction
- Grade 0: No contraction visible or palpable
