| Energy Delivered | Delivers mechanical energy through acoustic shockwaves or radial pressure waves, depending on the system. | Delivers pulsed electromagnetic fields through a coil or loop. |
|---|
| Energy Distribution | Focused systems concentrate energy within a focal zone; radial systems distribute pressure waves outward from the applicator. | Creates a field around the loop; distribution depends on coil geometry, positioning, and signal characteristics. |
|---|
| Application Method | A handheld applicator is positioned against the selected treatment area. | A loop is positioned over, around, or near the selected body area. |
|---|
| Skin Contact & Gel | Requires acoustic coupling, typically using gel and appropriate coat preparation. | Generally requires no coupling gel or direct skin contact. |
|---|
| Treatment Coverage | Applicator placement targets a defined location; multiple sites usually require repositioning. | Loop size and shape determine field coverage; repositioning changes the exposed area. |
|---|
| Adjustable Parameters | Common settings include pulse count, repetition rate, and pressure or energy level, depending on technology. | Settings may include field intensity, pulse frequency, operating mode, and duration, depending on the device. |
|---|
| Sensation & Sound | Produces repeated mechanical pulses and equipment noise; tolerance varies with settings and treatment location. | Sensation and sound vary by system; some produce little sensation, while higher-output devices may cause perceptible stimulation. |
|---|
| Treatment Delivery & Recording | Delivery is commonly prescribed and recorded by treatment site, applicator, output setting, and pulse count. | Delivery is commonly prescribed and recorded by loop placement, signal settings, and exposure duration. |
