Electroencephalogram

Abducted 90 degrees to torso

Elevated 180 degrees above head

Adson’s test (30° abduction)

Elbows at side and to the back, hands up, shoulders pressed downward and back

Increase in amplitude of waveform tracings

Loss of pulsatility or flatline waveform in symptomatic position

Decrease in amplitude during resting position

Waveform tracings remain similar to baseline in all positions

Waveforms return to baseline amplitude within 5 minutes

Waveforms do not return to baseline amplitude for more than 10 minutes

Temperature increases rapidly after immersion

No change in waveform amplitude

Normal vascular response

Vasospastic disorder or Raynaud’s syndrome

Peripheral neuropathy

Infection

Raynaud’s syndrome

Fixed occlusive disease

Peripheral neuropathy

Normal physiologic variation

Allen Test

Doppler Ultrasound

Electrocardiogram

Chest X-ray

Arm/hand weakness with exercise

Reduced or absent pulses

Hand numbness/weakness/pain, position related

Increased sweating
