k. Duplex Ultrasound: Combines Doppler and conventional ultrasound for detailed imaging.

l. Treadmill Testing: Evaluates symptoms during physical activity.

m. Toe-Brachial Index (TBI): Similar to ABI, focusing on toe blood pressure.

n. Pulse Volume Recording (PVR): Measures blood volume changes with each pulse.

o. Skin Perfusion Pressure: Assesses skin blood flow in the affected area.

p. Electromyography (EMG): Measures electrical activity in muscles.

q. Tissue Oxygen Measurement: Evaluates oxygen levels in the affected tissues.
