Question 2

Use of single-impulse, focused acoustic sound
waves with rapid rise in pressure

Answer 2

Shock Wave Therapy

Question 3

ESWT Generated by

Answer 3

1. Reverse piezoelectric (electrical to mechanical energy)
2. Electromagnetic
3. Electrohydraulic

Question 4

O Because the pulse duration of the shock wave is extremely short (___) and is generated at low frequencies, it is minimally absorbed by the tissues and therefore no thermal effect is generated.
