What Is Electrotherapy Equipment?

Electrotherapy equipment uses controlled electrical stimulation as part of a clinical treatment program. Depending on the device, the equipment may provide one or several electrical stimulation waveforms, multiple treatment channels, predefined clinical protocols, customizable treatment settings, or other therapeutic modalities from the same platform.

Professional electrotherapy systems are generally designed for use in physical therapy clinics, rehabilitation centers, sports medicine facilities, hospitals, athletic training environments, and other healthcare settings.

Electrotherapy is a broad category. Equipment may include:

• Dedicated electrical stimulation systems
• Multi-channel electrotherapy machines
• Combination electrotherapy and ultrasound systems
• Expandable multi-modality therapy systems
• Portable stimulation devices
• TENS and EMS equipment
• Iontophoresis equipment
• Electrotherapy accessories and electrodes

The right type of equipment depends on the treatments provided by the facility, the number of patients treated, available space, clinician preferences, and whether multiple modalities need to be incorporated into one system.

 

Professional Electrotherapy Equipment vs. Consumer TENS Units

Although consumer TENS units and professional electrotherapy systems both use electrical stimulation, they are not necessarily interchangeable.

Simple TENS devices are typically designed around a smaller number of stimulation options and straightforward operation. Professional clinical electrotherapy equipment may provide substantially more control, including multiple independent channels, several waveform types, programmable treatment parameters, preset clinical protocols, patient controls, and integration with other therapeutic modalities.

When outfitting a physical therapy clinic, consider whether the equipment will be used primarily for basic electrical stimulation or as part of a broader clinical modality program.

 

Types of Electrotherapy Equipment for Physical Therapy Clinics

Professional electrotherapy equipment generally falls into several categories. Understanding these differences can make it easier to narrow the options.

Dedicated Electrotherapy Systems

A dedicated electrotherapy system focuses primarily on electrical stimulation. These machines can be a good fit for facilities that already have separate therapeutic ultrasound equipment or clinics that want a dedicated multi-channel stimulation platform.

The Richmar TheraTouch EX4, for example, provides four channels of electrotherapy without integrated therapeutic ultrasound.

The Dynatronics Dynatron Solaris Plus 706 provides another approach, offering up to five channels of stimulation along with the ability to expand the system with compatible TriWave Light Therapy or ThermoStim accessories.

Combination Electrotherapy and Ultrasound Systems

Combination therapy systems bring electrical stimulation and therapeutic ultrasound together in one platform. This can reduce the number of separate devices required in a treatment area and provide clinicians with access to multiple modalities from a single system.

The Richmar TheraTouch CX2 Combo combines two-channel electrotherapy with therapeutic ultrasound, while the Richmar TheraTouch CX4 Combo expands the platform to four electrotherapy channels.

Another option is the Dynatronics Dynatron Solaris Plus 709, which combines up to five stimulation channels with 1, 2, and 3 MHz therapeutic ultrasound and Dynatronics ComboPlus capability.

Expandable Multi-Modality Systems

Some professional platforms extend beyond conventional electrical stimulation and ultrasound. The Dynatron Solaris Plus platform, for example, supports optional TriWave Light Therapy and the ThermoStim Probe in addition to its electrotherapy capabilities.

This type of expandable system may be worth considering when a facility wants multiple therapeutic modalities integrated around the same equipment platform.

Portable and Compact Electrotherapy Devices

Smaller electrotherapy units may be useful when equipment needs to move between treatment rooms or when space is limited. Portability should be evaluated alongside waveform availability, treatment channels, controls, battery capability, accessories, and intended clinical use.

 

2-Channel, 4-Channel & 5-Channel Electrotherapy Equipment

One of the most important specifications to compare is the number of electrotherapy channels.

A channel represents an independently controlled electrical stimulation output. Professional systems can provide different channel configurations depending on the model. For example, the Richmar TheraTouch CX2 provides two channels, the EX4 and CX4 provide four channels, and the Dynatron Solaris Plus 706 and 709 can provide up to five channels of stimulation.

When a 2-Channel System May Make Sense

A two-channel electrotherapy system can be a good option for clinics that want a more compact platform and do not routinely require additional stimulation channels at the same time.

Two-channel combination systems can also provide an efficient way to add both therapeutic ultrasound and electrotherapy without purchasing a larger multi-channel platform.

When a 4-Channel System May Make Sense

Four-channel systems provide greater output flexibility for facilities that regularly use multiple stimulation channels. Clinics comparing equipment should consider not just the maximum number of channels, but how often those additional outputs are actually required in everyday treatment workflows.

When a 5-Channel System May Make Sense

Five-channel platforms such as the Dynatron Solaris Plus 706 and 709 provide another level of treatment capacity. Dynatronics designs the channels for fully independent treatment setups, which may be useful for facilities looking for a high-capacity professional modality system.

The number of channels should still be evaluated against actual clinical needs. More available outputs do not automatically make a system the right choice for every facility.

 

Common Electrotherapy Waveforms Explained

The number of channels is only one part of comparing electrotherapy equipment. Different systems also provide different electrical stimulation waveforms.

The terminology can be confusing when comparing machines, so it helps to understand the major waveform categories commonly found on professional clinical systems.

Interferential Current

Interferential current uses intersecting electrical currents and is a common waveform option on professional electrotherapy systems. When comparing equipment, look at the available controls and protocols associated with the waveform rather than assuming every machine implements it identically.

Premodulated Current

Premodulated stimulation is another waveform commonly included on clinical electrotherapy equipment. Unlike interferential stimulation generated through multiple intersecting currents at the treatment area, the modulation is produced by the device before the current reaches the electrodes.

Biphasic Stimulation

Biphasic waveforms use electrical pulses containing two phases. Depending on the equipment, clinicians may find different biphasic configurations and parameter controls.

TENS

TENS, or transcutaneous electrical nerve stimulation, is one of the best-known forms of electrical stimulation. While standalone TENS devices are widely available, professional electrotherapy systems may incorporate related stimulation waveforms and substantially more parameter control.

NMS

NMS, or neuromuscular stimulation, is another mode found on some clinical electrotherapy systems. Facilities comparing equipment should review the available parameters, protocols, and channel capabilities offered by each device.

Russian Stimulation

Russian stimulation is a commonly recognized electrical stimulation waveform available on many professional electrotherapy platforms. It is especially important to confirm waveform availability when replacing an older system if clinicians already use specific modes as part of established protocols.

High Volt

High-voltage pulsed current, often listed as High Volt, is another waveform available on multi-mode clinical electrotherapy systems, including Dynatron Solaris Plus and several Richmar systems.

Microcurrent

Microcurrent operates at much lower electrical current levels than many conventional stimulation modes. Not every electrotherapy device includes microcurrent, so clinics that require it should confirm the feature before purchasing.

RAAS

RAAS stands for Rapid Agonist Antagonist Sequencing. Richmar includes RAAS among the stimulation options available on several TheraTouch electrotherapy systems.

The most important consideration is not necessarily finding the system with the longest waveform list. Clinics should prioritize the modes they actually use, ease of programming, available clinical protocols, and compatibility with their treatment approach.

 

Dedicated Electrotherapy vs. Combination & Multi-Modality Equipment

Another major buying decision is whether to purchase a dedicated electrotherapy system, a combination electrotherapy and ultrasound system, or a platform capable of supporting additional modalities.

Advantages of Dedicated Electrotherapy Equipment

• Focuses on electrical stimulation capabilities
• Can complement existing standalone ultrasound equipment
• May avoid paying for a modality the clinic already owns
• Can provide multiple stimulation channels from a dedicated platform

Advantages of Combination Therapy Equipment

• Combines therapeutic ultrasound and electrotherapy in one system
• Can reduce the number of separate devices required in a treatment area
• Provides access to multiple modalities through one platform
• May simplify equipment organization and cart setup
• Can support combination ultrasound and stimulation capabilities when provided by the system

Advantages of Expandable Multi-Modality Platforms

• Can extend the equipment beyond conventional stimulation
• May support additional modalities through compatible accessories
• Can consolidate multiple treatment capabilities around one platform
• May provide a more flexible path for adding capabilities later

The Dynatron Solaris Plus platform is an example of this approach. The 706 and 709 can support optional TriWave Light Therapy or the ThermoStim Probe, while the 709 also includes therapeutic ultrasound.

A clinic that already has adequate ultrasound equipment may prefer a dedicated electrotherapy machine. A new clinic or facility replacing several older modalities may find a combination or expandable multi-modality system more practical.

 

What to Look for When Buying Electrotherapy Equipment

Before purchasing an electrotherapy system, compare the equipment using the criteria that will have the greatest effect on your clinic's workflow.

1. Number of Treatment Channels

Determine how many stimulation channels are appropriate for your normal treatment workflow. Professional systems are available with two, four, five, and other channel configurations.

2. Available Waveforms

Review the waveform list carefully. Common options can include interferential, premodulated, biphasic, NMS, Russian, High Volt, microcurrent, and other manufacturer-specific modes.

3. Therapeutic Ultrasound Capability

If the clinic also needs ultrasound therapy, decide whether a combination system makes more sense than separate devices. Available ultrasound frequencies vary by system. Richmar TheraTouch combination systems provide 1 MHz and 3 MHz ultrasound, while the Dynatron Solaris Plus 709 provides 1, 2, and 3 MHz ultrasound.

4. Expandable Treatment Modalities

Consider whether the clinic wants the system to remain focused on electrotherapy and ultrasound or support additional treatment capabilities.

For example, compatible Dynatron Solaris Plus equipment can be expanded with the DCP3 TriWave Light Therapy Probe, DLP3 TriWave Light Therapy Pads, or ThermoStim Probe DTSP1.

5. Preset Clinical Protocols

Clinical protocols can help clinicians navigate commonly used device settings. Compare both the available protocols and how easily treatment parameters can be adjusted.

6. Customizable Programs

If clinicians regularly modify parameters, look for equipment that allows treatment settings to be customized or frequently used programs to be stored when supported by the system.

7. User Interface

Touchscreen controls, touchpads, menu organization, clear parameter displays, and intuitive navigation can make a meaningful difference when equipment is used throughout the day.

8. Treatment Setup and Guidance

Manufacturers take different approaches to treatment setup. Some systems provide touchscreen-based protocols and guidance, while others incorporate controls such as Dynatronics' Target touchpad for positioning the center of an interferential treatment.

9. Patient Controls

Depending on the system, a patient interrupt switch or remote may allow the patient to alert the clinician or interrupt treatment according to the manufacturer's design.

10. Portability and Cart Options

Consider where the equipment will be used. A compact unit may fit easily on an existing counter or treatment cart, while a dedicated manufacturer cart can provide storage, cable organization, mobility, and a consistent equipment station.

Dynatronics offers a dedicated Solaris Plus Cart with three large storage drawers for compatible equipment and accessories.

11. Accessories and Replacement Parts

Before selecting a system, review the availability of electrodes, cables, ultrasound applicators, carts, batteries, therapy applicators, and other replacement accessories.

For Richmar combination systems, TheraTouch replacement ultrasound applicators are available for compatible equipment.

Dynatron Solaris Plus users can also expand compatible equipment with TriWave Light Therapy and ThermoStim accessories.

12. Warranty and Manufacturer Support

Electrotherapy systems are long-term clinical equipment purchases. Manufacturer warranty coverage, accessory availability, technical documentation, and ongoing product support should be considered alongside the initial equipment price.

Which Electrotherapy System Is Right for Your Facility?

There is no single electrotherapy system that is ideal for every rehabilitation facility. Start by evaluating how the equipment will actually be used.

Consider a Dedicated Electrotherapy System If:

• Your facility already has therapeutic ultrasound equipment
• You primarily need electrical stimulation
• You want a dedicated unit for an electrotherapy treatment area
• You want to avoid duplicating an ultrasound modality you already own

Examples include the four-channel Richmar TheraTouch EX4 and five-channel Dynatron Solaris Plus 706.

Consider a 2-Channel Combination System If:

• You want electrotherapy and ultrasound in one device
• Two stimulation channels meet your typical workflow
• Compact equipment is important
• Portability is a priority

The Richmar TheraTouch CX2 is an example of this configuration.

Consider a 4-Channel Combination System If:

• You want both therapeutic ultrasound and electrotherapy
• Your clinic requires up to four stimulation channels
• You prefer a more comprehensive combination therapy platform
• The equipment will serve as a central modality station

The Richmar TheraTouch CX4 provides this configuration.

Consider a 5-Channel Expandable System If:

• You want up to five stimulation channels
• Fully independent stimulation treatment setups are important
• You want the option to add TriWave Light Therapy
• You want the option to add ThermoStim
• You want to choose between a stimulation-only platform and a system with integrated ultrasound

The Dynatron Solaris Plus 706 provides the stimulation-focused configuration, while the Solaris Plus 709 adds therapeutic ultrasound.

The best approach is to purchase based on the treatments your facility actually performs rather than choosing the machine with the greatest number of specifications.
