  2. 2. THE USES OF ELECTROTHERAPY IN REHABILITATION Electrotherapy Machines are a popular modality used in physical therapy and rehabilitation. Electrotherapy (also known as electrical muscle stimulation or e-stim) uses an electrical machine that delivers electrical impulses to a patient’s body. This stimulation is done in order to promote and facilitate muscle healing and tissue regeneration. Not only is electrotherapy a popular modality in physical therapy, but can also be used by other rehabilitation practitioners because it has several numerous therapeutic benefits.
  3. 3. The use of electrotherapy has been supported by the American Physical Therapy Association because it has shown to provide the following: • Relaxation of muscle spasms • Prevention and cessation of muscular atrophy due to disuse • Improved local blood circulation and flow • Re-education of muscles using targeted stimulation • Preserve and improve range of motion • Management and reduction of pain (chronic, post-traumatic, and post-surgical acute) • Prevention of deep vein thrombosis post- surgery • Facilitation of wound healing • Improvement in the effectiveness in delivering prescription drugs- electromotive drug administration (EMDA)
  4. 4. How Does Electrical Stimulation Therapy Work? Electrotherapeutic devices can offer different therapeutic waveforms. An electrical stimulation device includes electrodes that are attached to the treatment area and when activated, the electrical energy of the device causes the muscles to contract. This contraction imitates the body’s natural movement during activity and can prevent muscular atrophy.
  5. 5. The most common waveforms found in electrical stimulation are: TENS, Russian, Interferential, Premodulated, Biphasic, High Voltage and Microcurrent. Each waveform has its own therapeutic benefits, so many devices may offer the practitioner multiple waveforms in order to offer them the most use across diverse patient
  6. 6. Different Waveforms Used in Stimulation Therapy The various waveforms used in e-stim are designed to target specific areas of the body and to provide customized forms of energy transfer. This variance in energy transfer helps address diverse therapy needs.
  7. 7. Transcutaneous Electrical Neural Stimulator (TENS) TENS works to decrease pain by blocking pain signals from reaching the brain. The stimulation of TENS also encourages the production of endorphins, making it a popular waveform for treating neck and back pain.
  8. 8. Russian Current The Russian Current waveform delivers medium frequency in alternating pulses of energy. This makes it a popular waveform to use when there is a need to increase muscle strength and re-educate specific areas. The Russian current can also stimulate the relief of pain-relieving endorphins, increasing its versatility and applications.
  9. 9. Interferential Current (IFC) Interferential Current (also referred to as IFC) is the waveform to use when treating chronic, post-surgical and post-trauma acute pain. IFC e- stim is non-invasive with minimal side effects. IFC delivers higher frequency energy so it crosses the skin barrier easier for deeper access into areas of pain, but also has improved tolerance.
  10. 10. Premodulated Current (Premod) Premodulated Current, also referred to as “premod”, is similar to interferential current. The main difference is that with premod current, a single channel is used to mix the frequencies prior to before current reaches the patient. This makes it a good choice when treating smaller areas of the body like: elbows, ankles, feet, or hands.
  11. 11. Biphasic Current "Biphasic" has two pulses of 2 different intensities. These alternate during treatment which makes it very versatile. Biphasic can be used for both acute and chronic problems for different goals including: • Strengthening & re- educating muscles • Improving blood circulation • Decreasing edema & swelling
  12. 12. High Voltage High Voltage electrical stimulation is a monophasic waveform which uses polarity (positive or negative) to stimulate the tissue. This is a popular modality to aid in decreasing pain and swelling, reducing muscle spasms and facilitating wound healing.
  13. 13. Microcurrent Microcurrent is also used for wound healing, utilizing micro-size, pulsing current. Because of its low intensity, Microcurrent is the most tolerated waveform in electrotherapy.
  14. 14. How Electrotherapy Can Be Used in Physical Therapy Used alone or in conjunction with other modalities, such as therapeutic ultrasound, electrotherapy can be used in physical therapy to treat many diverse patient issues including: • Sciatica • Fibromyalgia • Arthritis • Bursitis • Post-Surgical Pain & Swelling • TMD • Complications associated with Diabetes • Tennis Elbow • Carpal Tunnel Syndrome
  15. 15. Scientifically Supported Treatment for Pain & Swelling Electrotherapy is scientifically supported as being a useful modality to reduce both pain and swelling while improving healing outcomes for diverse patient groups.
  16. 16. 1. A study published in Current Rheumatology found that daily 30-minute TENS treatments for a period of 10 days was able to reduce acute, emergent and postoperative pain.
  17. 17. 2. An article, Sports Medicine studies the positive use of electrical stimulation in reducing swelling and edema caused by sports-related injuries.
  18. 18. 3. The Belgium Orthopedic Journal published promising results that showed TENS treatments to Achilles tendon injuries may actually facilitate healing.
  19. 19. 4. A study published in the Journal of the American Physical Therapy Association found that electrotherapy helped patients regain femoral strength following total knee arthroplasty (TKA).
  20. 20. 5. A study published in Experimental & Translational Stroke Medicine found that electrical stimulation improved hand motor recovery in stroke patients.
  21. 21. Whether treating acute injuries or chronic pain, electrotherapy, with its various waveforms, offer physical therapists the ability to non-invasively treat many diverse patient issues without complications or side effects.
  22. 22. With available portable units, electrotherapy can also be used by patients in home and office settings in order to provide them with a therapeutic alternative to traditional oral pain medications. These benefits make electrotherapy one of the most powerful and popular modality in physical therapy.
