MMT Principles Flashcards
Manual resistance should always be applied in the…
Direction of the line of pull
Apply resistance at the end of the range for consistency
One joint muscles
Apply resistance at or near mid range. Point of maximum resistance
Two joint muscles
Resistance should be applied…
Near distal end of segment to which the muscle attaches
Resistant should be applied at a ___ degree angle
90
Weakened muscle testing occurs in the ______ plane
Transverse
When testing a two joint muscle stabilize…
Proximal to the joint where movement occurs
Don’t do it
Contraindications
Examiner cannot break the patient’s hold position
Grade 5 normal
Muscle group is able to complete a full ROM against gravity and can tolerate some resistance
Grade 4 good
Muscle group can complete a full ROM against gravity
Grade 3 fair
Can complete a full range of motion in gravity minimal position
Grade 2 poor
Can detect some contractile activity in gravity minimal position
Grade 1 trace
Muscle is completely inactive
Grade 0
Mild resistance can be given in normal position
3+/5
Maximum resistance can be given in gravity minimal position and patient has full ROM
2+/5
Muscle can complete partial ROM in the gravity minimal position
2-/5
When any condition limits joint ROM the patient can perform only within the range available
Available ROM
The maximum amount of tension a muscle group can voluntarily exert in one maximum effort
Muscle strength
The tendency of a force to turn a lever around an axis of rotation
Torque
Ability of a muscle group to perform repeated contractions against resistance or maintain an isometric contraction for a period of time
Muscle endurance
Muscle that makes the major contribution of movement
Agonist
Muscle that has an opposite action to the prime mover
Antagonist
Muscle that contracts and works along with the agonist
Synergist
