3 TOS & Neural Tension Flashcards
What’s Thoracic Outlet Syndrome (TOS)?
Complex of S/S that result from compression of the neurovascular bundle (NB).
What’s the Neurovascular Bundle (NB)?
- brachial plexus
- subclavian vein
- subclavian artery
Where does the Brachial Plexus originate and travel?
- originates C5-T1
- enters between anterior and middle scalene
- under the clavicle
- over the 1st rib
- under the coracoid process posterior to (under) pec minor
What are some possible causes of TOS?
- cervical rib (juts out from C7 – not everyone has one)
- reduced interscalene triangle (ant. scalene syndrome)
- decreased costoclavicular space (costoclavicular syndrome)
- decreased spaced caused by shoulder drop
- callus formation resulting from a clavicular fracture
- also consider nerve root compression
Are ruleouts for frozen shoulder conducted uni or bilaterally?
unilateral (all ruleouts are unilateral except for spine)
What ruleouts are conducted for TOS?
- cervical spine
- shoulder
- thoracic spine (same as lumbar with overpressure)
- elbow
- TMJ
- maybe wrist (flx, ext, uln and rad dev)
How is Adson’s maneuver conducted?
What’s a positive sign?
What’s tested?
What’s tested: NB exit through ant and mid scalenes
How is Travell’s Variation/Halstead Maneuver conducted?
What’s a positive sign?
What’s tested?
What’s tested: NB exit between ant and mid scalene, but this one focuses more on mid scalene
How is Costoclavicular Syndrome Test/Military Stance conducted?
What’s a positive sign?
What’s tested?
How is Wright’s Hyperabduction Test conducted?
What’s a positive sign?
What’s tested?
How is Roos Test/Elevated Arm Stress Test conducted?
What’s a positive sign?
What’s tested?
How is Allen’s Test for the should conducted?
What’s a positive sign?
What’s tested?
What’s the aka for Neural Tension Testing?
aka flossing
What are some indications to perform Neural Tension Testing (aka flossing)?
- presence of adhesive scar tissue around the nerves
- increased pressure on surrounding tissues or nerves (e.g. from increased muscle tone, swelling)
What are some contraindications for Neural Tension Testing (aka flossing)?
- acute inflammatory or unstable neurological signs
- spinal cord injuries
