Electrotherapy Machines, Devices, & Supplies - Ultrasound Therapy

Electrotherapy is a generic name given to a variety of treatments using electrical signals. These interfere with neural pain signals and prevent them from reaching the brain. This helps ease the pain, which is one of the most common uses for EMS units. Nerve fibers respond to different amplitudes and frequencies. This means that the nervous system can be stimulated in many different ways.

Electrotherapy machines can also be used to speed tissue healing. This is because the body has its own bioelectric system. When applying electrical stimulation, it jumpstarts or accelerates the natural healing process. Conductivity gels and sprays ease the delivery of electric shocks.

The first recorded treatment dates back to 1743. However, electrotherapy made its way into the mainstream in the 1850s. This is when large shocks were replaced with more measured doses, known as the minimum effective. Iontophoresis, which helps deliver drugs through the skin, was coined before 1908. It is now finally gaining traction and heading towards wider adoption.

Ultrasound Therapy — Used for tissue healing and relaxation. It also improves local blood flow and increases healing rates. It is used with a conductivity gel. Deep tissue ultrasound machines help activate connective tissue. They are often used in sports medicine centers.

Laser Therapy — Low-intensity laser light relieves pain and promotes healing. It targets damaged muscles, tendons, or ligaments.

Transcutaneous Electrical Nerve Stimulation (TENS) — Uses a mild electrical current to relieve pain and relax muscles. TENS units are small, battery-operated devices connected to electrodes. They can also stimulate the production of endorphins.

Iontophoresis — A pain-free and non-invasive method of drug delivery through the skin. It comes in the form of electrode patches that stretch and adhere to most areas. Often used to treat rotator cuff tendinitis, tennis elbow, and plantar fasciitis.

Interferential Therapy — Uses medium frequency currents without creating discomfort to the patients. It is the most common electrotherapy for chronic pain after surgery, trauma, or injury.

Electrical Muscle Stimulation (EMS) — EMS units stimulate muscle contraction to strengthen them and reduce swelling. They are also used to relieve pain and help heal wounds faster. Also known as Neuromuscular Electrical Stimulation (NMS).

Electrotherapy devices are always accompanied by manuals and some have preset clinical protocols. Some electrotherapy machines can only be bought and used by medical professionals. You will need conductivity gels and sprays for ultrasound devices and electrodes and wraps for TENS units. Other common accessories to consider are electrotherapy machine cords, plugs, and adapters.

Ultrasound therapy is a common electrotherapy modality, but only one of many. Ultrasound uses high-frequency sound waves to lessen pain, reduce edema, and promote tissue healing. Electrical stimulation implies sending electrical currents via electrodes to specific muscles. The most effective treatment is to combine the two methods.

First of all, you have to determine which therapy is right for your specific needs. If you want to treat muscular spasms, poor blood circulation, or muscle atrophy, look for EMS units. If you want to focus on wound healing and non-muscular pain relief, then TENS units are the answer. The best electrotherapy machines are those that can provide both modalities. Any added ones are a welcome bonus. For instance, some units also provide interferential (IF) and microcurrent modes.

Electrical impulses decrease nerve pain and chronic pain. Besides pain relief, electrotherapy can also stimulate muscle tissue. This prevents and treats atrophy. Due to its deep heating effect, ultrasound therapy improves local blood flow, especially in limbs. It is often used to treat tendonitis and knee meniscus tears. Notable electrotherapy benefits and uses also include faster healing of wounds and musculoskeletal injuries. As a bonus, electrotherapy devices have minimal to no side effects.
