MMT Flashcards
(31 cards)
Work produced per unit of time
Power
Ability of a muscle to contract repeatedly over time
Endurance
Forced exerted by a muscle or group of muscles to overcome resistance in one maximal effort
Strength
A muscle or muscle group that makes major contributions to the movement at the joint
Agonist
A muscle of muscle group that has an opposite action to the prime mover
Antagonist
A muscle that contracts and works along with the agonist or prime mover to produce the desired movement
Synergistic
Muscles that contract to prevent unwanted movements produced by the prime mover
Counteractin gor neutralizing synergistic
Two or more muscles that work together to produce the desired movement
Conjoint synergist
Muscles that prevent movement or control movement at joints proximal to the moving joint to provide a stable base
Stabilizing or fixating synergist
Why do we perform MMT?
Differential diagnosis, determine extent of peripheral nerve injury or spinal cord injury
Establish a baseline
Evaluate progress
Modify treatment
Determine strength of muscles
Determine effect of muscle length imbalances
Examine patient motivation and ability to follow directions
Precautions for MMT
Extreme pain or swelling Extreme weakness Osteoporosis Cardiac conditions Limited cognition or emotional status MD says no
Contraindications of MMT
Neoplasm Idiopathic pain Tissue inflammation Unhealed fracture Neoplasm Serious tear DVT
How would you perform a MMT
- Introduce, explain, demo
- Have Pt perform AROM and look for substitutions
- Position patient in correct position
- Expose muscle and joint
- Stabilize proximal components as necessary
- Encourage maximal effort
- Apply graded resistance
- Check pt status
- Record MMT
- Then do affected side
Break test
Most commonly used, resistance applied at distal end of segment to which the muscle attaches after pt completes AROM
More objective but difficult to asses functional strength and fatigue
Active resistive/ dynamic testing
Graded manual resistance against direction of ROM
Difficult to grade
Subjective
Used with certain medication conditions to assess endurance and patterns of substitutions
Initiates movement against gravity or gravity eliminated position with some resistance
2+
Does not complete full AROM against gravity
3-
Con tolerate strong resistance then muscle yields
4
Holds end position against resistance
3+
AROM against gravity
3
Muscle is completely quiet
0
Completes full ROM in GE position
2
Cannot break the hold against max resistance
5
The examiner can detect contractile activity, but no movement
