Electrotherapy and Therapeutic Ultrasound

Electrotherapy and therapeutic ultrasound are different physical-therapy technologies. Electrotherapy devices apply controlled electrical stimulation through electrodes, while therapeutic ultrasound systems use acoustic energy delivered through a treatment head and coupling medium.

Electrotherapy systems

Professional electrotherapy devices may provide multiple current types and channel configurations. Depending on the device and clinical protocol, they can support neuromuscular stimulation, pain-management workflows and other physiotherapy applications.

Therapeutic ultrasound

Ultrasound devices typically offer one or more operating frequencies, treatment-head options, continuous or pulsed modes and adjustable output. Correct coupling and applicator handling are important for safe and consistent use.

How should a clinic compare devices?

• Available modalities and channel configuration
• Ultrasound frequency and head options
• Protocol management and user interface
• Safety controls and calibration requirements
• Applicators, electrodes and consumables
• Training, warranty and technical service

These technologies have different indications and should not be selected solely on the basis of device specifications. Clinical use should follow professional assessment, current guidance and manufacturer instructions.
