TENS Unit For Sciatica: What It Is, How To Use, and Operation Guidelines

Transcutaneous Electrical Nerve Stimulation (TENS) is a type of non-invasive electrotherapy for short-term pain relief. It uses electrode pads to deliver electric stimulation to the body. Using a TENS unit for sciatica is simple. The user must identify where the pain originates and place the pads near or on the origin of the pain. However, it is best to consult a medical professional before using TENS. They may advise on the regularity, duration, and settings to use during treatment.

Many people benefit from using TENS therapy. It is an effective method of pain relief for many chronic and acute pain conditions. Many doctors and physical therapists include this in their treatment plans because it complements other treatments. Additionally, it helps people reduce their intake of oral pain medications. This article will present what a TENS unit is, how to use one, and the safety guidelines for using it.

What is a TENS Unit for Sciatica and How Does it Work

A TENS unit for sciatica provides pain relief using high and low frequencies of electrical stimulation. It uses electrode pads to deliver the electric currents to the skin and into the body. Typically, TENS machines have a frequency range of 1-150 Hz and an intensity range of 0-80 mA. There are wired and wireless options for TENS devices available. They are battery-operated devices, and users adjust the settings using controllers. People may buy them online or in pharmacies without prescriptions.

Using high-frequency stimulation (50-120 Hz) triggers the spinal nerve cells to block pain signals from reaching the brain. This is the mechanism described in the Gate Control Theory of Pain. For many, it takes effect within 30 minutes of the session. This is suitable for acute pain conditions.

Meanwhile, low-frequency stimulation (2-10 Hz) triggers the production of endorphins. These are painkilling hormones that build up to relieve pain. It takes around 40 minutes before it takes effect. However, it helps with chronic pain because its effects last hours after the session.

Benefits of Using the Device

TENS machines are effective in chronic and acute pain conditions. There are several benefits of using TENS. Here are some of them:

  • TENS therapy allows people to reduce or replace their intake of pain medications. This is helpful for those who experience allergic reactions and wish to avoid the adverse effects of pain medicines.
  • It is complementary to other treatments because of its non-invasive nature.
  • It has a massage-like effect that increases blood flow and relaxes the muscles. This may help reduce fatigue and speed up healing.
  • Endorphins help reduce inflammation and improve moods. This enables people to do more activities like exercise.

How to Use a TENS Unit for Sciatica

Using a TENS unit for sciatica is simple and easy. Before starting, clean the skin with soap and water and dry it. This removes excess oils and allows the electrode pads to stick better. Then, they may attach the pads to near or on the origin of the aches. Once the adhesives are secure, the user may turn the machine on. It is best to start on low settings to avoid sudden shock or discomfort.

Afterwards, they may gradually increase the settings according to their comfort levels. They may also select a preset mode. Sessions generally last between 20 to 30 minutes. People may also follow the medical advice of their healthcare provider regarding the duration, regularity, and settings to use.

Once the time elapses, the user can switch their machine off. Afterwards, they can remove the electrode pad. It is best to clean the pads after use to lengthen their lifespan. Then, store them in a cool and dry area for future use. People may use TENS up to four times daily. However, people must take breaks in between to avoid adverse effects.

Correct Pad Placement for Effective Relief

Proper placement of electrode patches is crucial for effective pain relief. Sciatica is caused by injury or pressure to the sciatic nerve. To treat sciatic pain, the user must first identify where the discomfort or ache originates. Then, they may place the adhesive pads on the side of the affected area.

If the pain is concentrated on the lower back, the individual may place a pad on each side of the spine. They may also place a pad on the leg if the pain radiates down to it. Altogether, this will help focus the electrical currents on the sciatic nerve.

Safety Guidelines When Using a TENS Unit for Sciatica

While using a TENS unit for sciatica pain, it is crucial to stay alert and take precautions. It is best to consult a health professional before using electrotherapy devices. They can help assess if TENS is suited for the condition. Moreover, some health conditions react negatively to electric stimulation. This includes those with a history of cancer, epilepsy, seizures, or heart disease. Additionally, people with electrical and metal implants should avoid using TENS.

Before using the device, it is ideal to read the guidelines of the device manufacturer. This will help the user understand how to use the device correctly. Additionally, people should avoid placing pads on irritated, infected, and broken skin. They should also avoid placing them in sensitive areas, such as the throat, chest, spine, or head.

Furthermore, TENS therapy should not be done while sleeping, driving, or operating heavy machinery. It is best to keep a safe distance from water to prevent accidental shocks. Lastly, regularly inspect the device for any damage. Broken electrodes or lead wires may cause mild burns or skin irritation.

When to Seek Medical Help

For people with sciatica pain, it is crucial to seek medical attention so medical professionals may assess the condition. While TENS provides effective pain relief, it does heal the injury directly. Furthermore, if the user experiences worsening pain during or after the session, they should seek help from healthcare professionals.

Moreover, consulting health professionals is ideal if they experience allergic reactions, excessive muscle twitching, or tingling sensations after the session. Lastly, the appearance of symptoms such as loss of bladder or bowel control, weakness in the legs, and difficulty walking may indicate a severe underlying condition.

Conclusion

Many people use a TENS unit for sciatica with other physical therapy methods. A TENS machine uses electrical pulses delivered through an electrode pad for temporary pain relief. It works by blocking pain signals and inducing endorphin production. These machines are designed to be easy to use. Individuals place the pads near or on the origin of the pain. Then, they may start using the device for 20 to 30-minute sessions.

However, it is vital to ensure safety while using TENS. It is best to consult a medical professional to ensure TENS suits the health condition. In addition, reading the guidelines from the product manufacturer is crucial before using it. There are many wired and wireless options available online and in physical stores. One option is the iTENS from iTENS Australia. It is a reliable wireless TENS device that uses wing-shaped electrodes.
