Sciatica is one of the most common, yet misunderstood, types of pain.
According to Harvard Health, as many as 40% of people will experience it during their lifetime, and it becomes more frequent as they age.
In general, an estimated 5%-10% of patients with low back pain have sciatica, whereas the reported lifetime prevalence of low back pain ranges from 49% to 70%.
While sciatica remains a somewhat controversial subject, there is evidence that using Transcutaneous Electrical Nerve Stimulation (TENS) can reduce pain intensity in people with both acute and chronic pain compared to a placebo.
Specifically, studies suggest that TENS may help reduce, although not completely eliminate, the severity of sciatica pain. If you're considering a TENS unit for sciatica relief, this guide will help you navigate the options and choose the best device for your needs.
What Is a Tens Unit & How Does It Work?
A TENS unit, or Transcutaneous Electrical Nerve Stimulation unit, is a compact, portable device designed to provide temporary relief from various types of pain, including sciatica, arthritis, and muscle aches. But how does this small gadget actually work?
How TENS UNIT Works
The TENS unit sends gentle electrical pulses to your nerves through electrodes that are placed on your skin. These pulses work by stimulating the nerves, which helps to block pain signals from reaching the brain and reduces the intensity of muscle spasms. The device allows you to adjust both the frequency and intensity of the pulses, so you can find the settings that are most comfortable and effective for you.
Here’s how the TENS unit provides pain relief:
-
Gate Control Theory
The Gate Control Theory of Pain explains that our spinal cord contains a “gate” that either allows or blocks pain signals from traveling to the brain.
When the TENS unit stimulates your nerves, it can effectively "close the gate," preventing pain signals from getting through. As a result, you feel less pain.
2. Endorphin ReleaseThe TENS unit also encourages the release of endorphins, which are your body’s natural painkillers. These chemicals help to reduce pain and create a sense of well-being, adding another layer of relief.
3. Muscle Relaxation
By controlling muscle tension and reducing spasms, the TENS unit helps to ease nerve pain and provides temporary relief from discomfort. This relaxation of muscles can be especially beneficial for those dealing with chronic pain conditions like sciatica.
How To Choose The Best TENS Unit?
When it comes to selecting the best TENS unit for sciatica relief, it's important to focus on features that will give you the most effective and comfortable experience. Here are key factors to consider:
Adjustable Intensity Levels
A good TENS unit machine must offer you the option of adjusting the degree of frequency and intensity of the electrical pulses.
These are necessary to find the most effective and comfortable settings. Therefore, look for a device that has adjustable frequency and intensity level settings.
Number of Electrodes
You will usually come across TENS units with two electrodes. However, if you search the market then there are some versions of the device that offer extra electrodes to offer you more relief.
Do you have multiple pain points?
Then look for the unit that has additional electrodes for more targeted pain relief.
Preset Programs
Choosing a TENS unit with preset programs can make your experience much more convenient.
These pre-programmed settings are designed to address different types of pain, so you can easily switch between modes depending on your specific needs. This feature is especially helpful if you’re new to using a TENS unit and want a straightforward way to manage your pain.
Battery Life
Long battery life is a crucial consideration, especially if you plan to use the TENS unit frequently. Look for models that come with rechargeable batteries or those that allow you to use disposable batteries. This ensures that your device is always ready when you need it and minimizes interruptions during treatment.
Touchscreen
A user-friendly screen makes a device easier to run and the same formula is applied in the case of a TENS unit. Look for this device, where you can get the hang of settings and control the settings of the electrical pulses in terms of intensity and frequency. Such a device can also benefit people who cannot move much due to old age or any kind of disability.
Safety Tips When Using a TENS Unit
Here are a few safety tips that you should keep in mind when using a TENS unit:
Avoid Open Wounds
Do not place electrodes directly over open wounds or sensitive areas.
Monitor for Side Effects
Watch for any skin irritation, discomfort, or other adverse reactions. If you experience any issues, discontinue use and consult a healthcare provider.
Proper Electrode Placement
Follow the manufacturer's instructions for correct electrode placement.
Pregnant Women
TENS units should not be used during pregnancy.
Individuals with Pacemakers
Individuals with pacemakers and other implanted devices should avoid using the device. Why? Because the electrical current from a TENS unit can interfere with these devices.
Is Tens Unit Safe to Use?
TENS units are generally safe when used correctly. However, it's essential to consult with a healthcare professional before using one, especially if you have underlying health conditions or are taking medications. They can provide guidance on proper usage and potential risks.
How Often & How Long to Use a Tens Unit?
The frequency and duration of TENS unit usage can vary depending on individual needs and the specific condition being treated. It's generally recommended to consult with a healthcare professional for personalized guidance. However, typical usage involves multiple sessions per day, each lasting from 20 to 30 minutes.
