HPD MSK Quiz
1. What are the movements of the cervical spine ROM?: Flexion/extension (45 degrees)
Left/Right rotation (80 degrees)
Left/right lateral flexion (45 degrees)
2. Which muscles does C5 innervate and which dermatome does it give sensa-
tion to?: Deltoid and biceps
- gives sensation to dermatome over deltoid
3. Which muscles and dermatome does C6 innervate?: Innervates over the dermatome of
lateral forearm and hand
- innervates the biceps and wrist extensors (extensor carpi radialis longus and brevis)
4. Which muscles and dermatome does C7 innervate?: Innervates the small dermatome over
middle finger and triceps, wrist flexors, and finger extensors
5. Which muscles and dermatome does C8 innervate?: - supplies dermatome of medial hand
and forearm
,- also finger flexors
6. Which muscles and dermatome does T1 innervate?: - supplies intrinsic muscles of the
hand
- the interossei (adductors/abductors)
- dermatome on the medial upper arm
7. What is the spurling compressing test also known as?: Foraminal compression test
8. What are the red flags that must be ruled out with a shoulder complaint?: -
injury with fracture (proximal humerus)
- septic bursa or joint
- acute rotator cuff injury (tear), partial tears only picked up on MRI
- acute injury
- high risk injury/osteoporosis
- minimal or NO motor strength (drop arm)
- fever, chills
- severe pain
9. Which manuever assesses overall shoulder rotation?: Apley scratch test
10. What are the SITS muscles and their function?: Supraspinatus - abducts or flexes arm
,Infraspinatus - externally rotates shoulder
, Teres minor - externally rotates and adducts arm
Subscapularis - internally rotates shoulder
11. What is the "golf ball on a tee" analogy with the shoulder?: Humeral head - golf ball
Glenoid - golf tee
Scapula - stick in ground
12. What is the function of the rotator cuff?: - attempts to stabilize shoulder joint by compressing
humerus and keeping it centered
13. What is the function of the glenoid labrum?: - deepens the socket that holds head of humerus
and stabilizes shoulder joint
14. What is the shoulder pain cycle?: 1. Pain ("tendonitis", "bursitis")
2. Weakness
3. Instability
4. Impingement
15. What history and exam will you perform for complaint of shoulder instabili-
ty?: History
- dislocation
