A
- C1-C2: cervical flexion
- C3: cervical side flexion
- C4: scapular elevation
- C5: Shoulder abduction
- C6: elbow flexion and wrist extension
- C7: elbow extension and wrist flexion
- C8: thumb extension
- T1: finger abduction
5
Q
Lower quarter myotomes:
A
- L1-2: hip flexion
- L3: knee extension
- L4: ankle dorsiflexion
- L5: big toe extension
- S1: ankle eversion and plantar flexion, hip extension
- S2: knee flexion
- S3: no specific test; intrinsic foot muscles
6
Q
Morton Neuroma
A
- ball of nerves that forms a tumor
- typically between 3rd and 4th metatarsals
- burning, tingling in forefoot interspaces of toes while walking
7
Q
causes of mortons neuroma
A
- inadequate footwear
- excessive pronation
- arthritis
8
Q
Thoracic outlet syndrome types
A
- vascular TOS 5%
- neurogenic 95%
9
Q
TOS: etiology of symptoms
A
- compressive neuropathy
- faulty posutre most common
- entrapment of neural tissue from scar tissue or pressure
10
Q
Assessing Vascular TOS
A
- 3 minute elevated test
- adson test
- swelling
- discoloration of hand
- costclavicular test
- hyperabduction test
- UE claudication
- differences in BP
- skin temperature changes
- cold intolerance
11
Q
Neural TOS assessment
A
- point tenderness of C5-C6
- pressure over lateral neck elicits pain and or numbness
- pain with head turned and or tilted to opposite side
- weak biceps
- weak triceps
- weak wrist
- hypoesthesia in radial nerve distribution
- 3 minute abduction stress test
12
Q
what are comme compression/entrapment sites in TOS
A
- interscalene triangle
- costoclavicular space
- rectropectoralis minor space
13
Q
Ulnar nerve compression in tunnel of guyon
A
- claw hand
- atrophy between metacarpals
- atrophy with hypothenars
- loss of digits 4 and 5 for spherical and cylindrical power grips
14
Q
Carpal tunnel syndrome
A
- median nerve
- hand involvement without the palm
- phalens and reverse phalens
15
Q
radial nerve compression: radial groove
A
- fracture or compression. (saturday night palsy)
- triceps spared
- weakness: wrist extension
- sensory loss: dorsum of hand dorsum of fingers 1-4
-
16
Q
Radial nerve: supinator syndrome
A
- posterior interosseus nerve
- weakness: finger extesnors
- spared: brachioradialis, wrist extensor
- sensation
17

A
- PSIS
- lower lumbar spine (L5 - 72%)
- buttocks (94%)
- posterior lateral thigh (50%)
- knee to the ankle (14%)
- lateral foot (8%)
- abdominal (2%)
- groin or pubic (14%)
- anteiror thigh (10%)
