10 Questions
In middle trapezius muscle test, why might a patient exhibit excessive scapular downward rotation?
Dominance of the rhomboid muscles
The tightness of which muscle can lead to decreased shoulder external rotation?
Subscapularis
Why is stabilization crucial in manual muscle testing?
It isolates the muscle being tested
For the lower trapezius muscle test, what is the unique arm position required for testing?
130 degree shoulder abduction
The action of Deltoid (Posterior fibers) is
Horizontal abduction of the shoulder, with slight lateral rotation.
Flex patient's elbow, maintaining forearm in full pronation consider as a manual muscle test for
Brachialis
Which of the following is an equivalent documentation for the numerical strength 3/5?
Fair
Shortness of ......... results in a limitation of elevation of the arm in flexion and abduction
Latissimus dorsi
What is the significance of performing a gravity-eliminated test for patients with grades below 3 in manual muscle testing?
It provides a more comfortable position for the patient
Which of the following are correctly paired during upward or downward rotation of the scapula?
Rhomboid muscle - Pectoralis Minor
Study Notes
Muscle Testing and Scapular Rotation
- Excessive scapular downward rotation may occur in middle trapezius muscle test due to tightness of the levator scapulae muscle.
- Tightness of the subscapularis muscle can lead to decreased shoulder external rotation.
Importance of Stabilization
- Stabilization is crucial in manual muscle testing to ensure accurate results.
Lower Trapezius Muscle Test
- The unique arm position required for testing the lower trapezius muscle is with the arm in 120° of abduction and 10° of scapular plane.
Deltoid Muscle Test
- The action of the posterior fibers of the deltoid muscle is to flex the elbow, maintaining the forearm in full pronation.
Muscle Strength Documentation
- An equivalent documentation for the numerical strength 3/5 is "fair".
Muscle Shortness and Arm Elevation
- Shortness of the pectoralis minor muscle results in a limitation of elevation of the arm in flexion and abduction.
Gravity-Eliminated Testing
- Performing a gravity-eliminated test is significant for patients with grades below 3 in manual muscle testing to ensure accurate results.
Scapular Rotation
- The correctly paired muscles during upward or downward rotation of the scapula are the upper trapezius and lower trapezius, respectively.
This quiz assesses your understanding of the middle trapezius muscle test and its implications on scapular rotation. Learn about the possible reasons behind excessive scapular downward rotation in a patient. Gain insight into the anatomy and physiology of the shoulder muscles.
