RROM Flashcards
RROM
Resisted Range Of Motion
RROM is tested
Last
The joint that is being tested is put in a
Neutral or testing position
To keep movement to minimum, it is best for the examiner to position the joint properly in the resting position and then to say the patient…
“Don’t let me move you”
Examiner gradually loads force to desired movement until the muscle
Locks in
Once desired force is reached, examiner counts backwards
From 5-0
Examiner should observe the following during the resisted isometric movement
✓ Whether the contraction causes pain and, if it does, the pain’s intensity and quality
✓ Strength of contraction
✓ Type of contraction causing problem
No contraction palpated
0
Zero
Evidence of slight contractility but no joint motion
1
Trace
Initiates motion if gravity is eliminated
2-
Poor (-)
Complete ROM with gravity eliminated
2
Poor (25%)
Initiates motion against gravity
2+
Poor (+)
Some but not complete ROM against gravity
3-
Fair (-)
Complete ROM against gravity
3
Fair (50%)
Complete ROM against gravity with minimal resistance
3+
Fair (+)
Complete ROM against gravity with moderate resistance
4
Good (75%)
Complete ROM against gravity with maximal resistance
5
Normal (100%)
Causes of Muscle Weakness
✓ Muscle Strain
✓ Pain/Reflex Inhibition
✓ Peripheral Nerve Injury
✓ Nerve Root Lesion (Myotome)
✓ Upper Motor Neuron Lesion
✓ Tendon Pathology
✓ Avulsion
✓ Psychological Overlay
Patterns of Contractile Tissue and Nervous Tissue Lesions
✓ No Pain, and movement is strong
✓ Pain, and movement is relatively strong (but not as strong as it should be)
✓ Pain, and movement is weak
✓ No Pain, and movement is weak
Close Pack Position
the majority of joint structures are under maximum tension
(Should be avoided)
Loose Pack Position
“resting position”, which is the position in its ROM at which the joint is under the least amount of stress
Postural or Tonic muscles
muscles responsible for maintaining upright posture
Phasic muscles
include almost all other muscles
