Electrotherapy Units & TENS Machines

TENS machines

TENS stands for transcutaneous electrical nerve stimulation. These devices send controlled electrical impulses through electrodes placed on the skin. Models can differ by channel count, preset programs, adjustable parameters, timer functions, compliance tracking, display type and power source.

A straightforward portable TENS unit may be suitable when a healthcare professional has recommended a specific home-use protocol. Clinics may prefer models with additional programming controls, locking functions or treatment records.

EMS and TENS/EMS combination units

EMS, sometimes described as NMES, is designed to create controlled muscle stimulation. Combination devices provide TENS and EMS modes within one portable unit. Some advanced models also include interferential, microcurrent or Russian stimulation waveforms.

When comparing combination units, confirm which modes are included and whether the settings are appropriate for your prescribed or clinician-directed application. A device offering more waveforms is not automatically the best choice if those functions are not required.

Therapeutic ultrasound units and gel

Portable therapeutic ultrasound units use a treatment head that must maintain suitable contact with the skin. Conductive ultrasound gel helps support that contact during use. Compare each unit’s operating frequency, treatment-head specifications, controls, included accessories and intended setting before ordering.

Electrodes and replacement accessories

Electrodes are available in different dimensions, materials, connector styles and pack quantities. Replacement pads are not universally compatible with every device, so check the connector and product specifications before purchasing.

Electrotherapy for Clinics and Home Use

Physiotherapists, chiropractors, rehabilitation professionals and other authorized practitioners may require advanced electrotherapy equipment for clinical workflows. Explore our broader physiotherapy supplies collection for related rehabilitation products.

Home users should select only equipment appropriate for their needs and follow the exact instructions supplied with the device. Electrotherapy is not suitable for every person or every condition. If you are uncertain about device selection, electrode placement, treatment settings or contraindications, consult a qualified healthcare professional before use.
