What are 5 causes for muscle weakness?
. lower motor neuron disease
.primary muscle disease
.neurological diseases
.disuse/ immobilization
. secondary symptom
What is the difference between isometric and isotonic muscle contractions
isometric: no change in muscle length, causes stability
isotonic: concentric and eccentric actions that create movement.
contradictions for MMT/ ROMT
.inflation/ pain
.fracture/dislocation
.bone carcinoma
.osteoporosis
.myositis ossifans
5 Steps in preparation for testing
1. asses AROM
2.assess PROM
3.determine if full MMT or Gross MMT is needed
4.correctly position client
5. ensure test validly
Goniometer placement for shoulder flexion/extension
1" below acromion process
Goniometer placement for shoulder abduction
posterior GH joint
Goniometer placement for shoulder internal and external rotation
olecranon process
Goniometer placement for horizontal abduction and adduction
top of acromion process
Goniometer placement for elbow flexion/ extension
lateral epicondyle
Goniometer placement for forearm supination and pronation
center of 3rd proximal phalanx
Goniometer placement for wrist flexion/ extension
mid wrist
Goniometer placement ulnar and radial deviation
dorsum, middle wrist
MMT grading: normal (N), 5
complete ROM against gravity, max resistance
MMT grading: good plus (G+), 4+
Full ROM, can maintain mod resistance but breaks at max
MMT grading: good (G), 4
full ROM, mod resistance
MMT grading: good minus (G-), 4-
Full ROM, min assistance
MMT grading: fair plus (F+),3+
Full ROM, min assistance through partial ROM but abruptly breaks
MMT grading: fair (F), 3-
Not full ROM, gradual release of the test position
MMT grading: poor plus (P+), 2+
less than 1/2 ROM against gravity or full ROM in grav minimized position w min resistance.
MMT grading: poor (P),2
Full ROM in gravity minimized only and no resistance
MMT grading: poor minus (P-), 2-
Partial ROM in gravity minimized postioion
MMT grading: trace (T), 1
no joint motion but observable contraction
PROM
secondary individual is moving limb through patterns of muscles.
no effect of muscle tone or strength
SROM
client educated on how to do motion on their own
uneffected limb supports effected
AAROM
combined effort of outside force and the clients muscle strength
assistance is lessened as the client gains strength
AROM
how client moves w their own strength
know grav minimized positions
