Muscles Flashcards
Agonist
Muscle or muscle group that is most directly related to performing a specific movement
Anatagonist
or muscle group that can oppose the action or actions of the agonist
Synergist
Muscles that work together to perform a particular action
Stabiizer
A muscle that fixes or holds a body segment relatively stationary so that another muscle can more effectively perform an action
What are the key concepts that the PTA must do to protect the patient and themselves while performing goniometry and MMT
- stabilize the joint
- support of the joint
hypermobility documentation
5-0-135 elbow flexion
contraindications for goniometry and MMT
- unstable joint
- cancer in the joint
- severe osteoporosis
- muscle tear
Grade 5
The end ROM of a joint is held firmly still by the patient against resistance with no joint motion or bend
4
The muscle is strong enough to complete a full range of motion against gravity plus at the end ROM of a joint, resistance applied to the lever arm responses cause some give or yielding resulting in some joint motion or bend
3
The muscle is strong enough the move a joint through a full active ROM with gravity as resistance.
Overhead reaching dressing, washing
Grade 3 is not functional for lower extremities as the muscle must overcome the body’s weight to perform functional activities
2
FULL active ROM with gravity eliminated
1
Palpable or visual muscle contraction
Palpable activity of the tendon
At best partial ROM with gravity eliminate
0
No palpable or visual muscle activity
o What is the most important activity that the PTA should assess prior to performing an active resistive manual muscle test?
The patient must be able to complete full ROM against gravity.
