Transcutaneous Electrical Nerve Stimulation (TENS) is a form of electrotherapy for pain relief. TENS cervical therapy is a pain management method that uses electric currents to trigger the pain gate mechanism and endorphin production. It is through TENS machines with adjustable settings and externally applied electrode pads. To use one, attach the pads to the back of the neck, about two inches below the skull, and modify the settings accordingly. Sessions can last between 20 to 30 minutes.
Neck pain is a common issue that affects many people, leading to discomfort and decreased quality of life. It can develop because of poor posture, injuries, and medical conditions. To alleviate this ache, many turn to heating pads, therapeutic exercises, and pain medication. However, this may not provide sufficient relief. Hence, people look for other treatments for better outcomes. This article will present information on TENS therapy for the cervical region, how it works, and how to operate TENS machines.
What is TENS Cervical Therapy?
TENS cervical therapy is an alternative treatment that uses electrical stimulation to alleviate aches in the neck and cervical area. It involves applying electrodes to the skin to deliver the treatment. There are many benefits to using electrotherapy. As such, TENS is growing in popularity for providing effective treatment.
Many people use TENS machines in healthcare settings to improve the pain from several conditions. Individuals can also use convenient personal machines to conduct a therapy session for cervical pain. They are available without prescriptions and do not require medical supervision to use. Many have user-friendly settings to make operations smoother.
Generally, TENS machines come in two types. Traditional units utilise lead cables to connect the pads to the control unit. These are more common since they can be relatively inexpensive. Meanwhile, wireless units have Bluetooth capabilities, which allow them to connect to the control unit wirelessly. They tend to have more advanced features, such as smartphone connectivity and a wider range of programs.
Benefits of Using TENS
- Non-invasive: TENS does not use invasive methods, eliminating the risks of complications that may occur after surgery or injections.
- Drug-free: TENS therapy does not require medicines to work. It provides neck pain relief that can help people reduce their intake of pain medications.
- Portable: Many TENS machines have lightweight and compact designs, making them easy to carry around and use whenever needed.
- Complementary: TENS is an adjunct treatment that works well with other methods like physical therapy.
- Versatile: Besides chronic neck pain, TENS can address different types of pain. These include shoulder pain, headaches, postoperative pain, and musculoskeletal pain conditions.
How Does TENS Cervical Therapy Work?
TENS cervical therapy uses electrical stimulation to activate different mechanisms in the body for complete relief. The low-voltage electrical currents travel from the power source to the electrodes that send the electric impulses to the skin. Users can adjust the stimulation levels by modifying the settings according to their needs and comfort. Different settings can bring varying results.
High-frequency stimulation (50-120 Hz) can induce the spinal nerve cells to block pain signals from reaching the brain for significant pain reduction. This is also known as the pain gate mechanism, proposed in the Gate Control Theory of Pain. It is ideal for acute pain management since it takes effect quickly. Moreover, high frequencies can help improve blood circulation and decrease muscle tension.
Meanwhile, low-frequency stimulation (2-10 Hz) triggers the production of endorphins. These hormones are natural pain relievers that block opioid receptors for a reduction in pain sensations. This results in longer-lasting relief of pain for chronic pain patients. However, it may take longer for patients with neck pain to feel the effects compared to using high frequencies.
Frequency of TENS Sessions
The frequency of the TENS sessions can vary depending on the individual, the specifics of their pain, and their overall health condition. For many, TENS is safe to use daily. Moreover, patients with chronic pain conditions may use this up to four times every day.
It is best to consult a healthcare provider before using TENS. They may guide the person on how to use the machine, including the recommended number of sessions. It is vital to follow their instructions to prevent adverse outcomes. The user should also take breaks between sessions to allow the skin to rest and avoid potential skin irritation.
How to Conduct TENS Cervical Therapy
Conducting TENS cervical therapy is an easy process. Due to the user-friendliness of TENS machines, people may self-administer their treatment. Before starting, wash the skin with soap and water to remove excess oils, lotions, and dirt. Clean skin can help with adhesion for the safety and effectiveness of the treatment session.
Start by applying the electrode pads of the appropriate size to the painful cervical region. Ensure they are secure before linking them to the control unit using Bluetooth or cords. Afterwards, turn on the TENS unit for neck pain and set a timer for the treatment duration, ranging from 20 to 60 minutes. Adjust the settings as needed for neck pain relief. Alternatively, select a preset treatment program for cervical pain if it is available.
Once the time elapses, turn the unit off before removing the electrodes. Clean the adhesives with a few drops of water and a cloth to maintain hygiene and stickiness. Lastly, store the machine and accessories in a cool and dry place.
Pad Placement Guide
Proper electrode placement is crucial for complete relief with TENS therapy. The rule of thumb when applying TENS pads is to place them on muscles near or on the pain source. The placement for neck pain is at the back of the neck, about two inches below the skull. Ensure at least an inch distance when using two or more TENS pads.
It is essential to avoid the sides of the neck and the throat since these are sensitive areas that may have adverse reactions to electrical nerve stimulation. Moreover, avoid irritated, infected, or broken skin patches since the electric currents may worsen the condition.
Conclusion
TENS cervical therapy is an effective method of alleviating aches in the cervical region. It uses a TENS machine to deliver electric stimulation to the sensory nerves and activate the pain gate mechanism. It also induces the production of natural pain relievers for lasting relief. Moreover, it reduces muscle tension and improves healing by increasing blood flow to the area. Many healthcare and pain management professionals include TENS in treatment programs because of their benefits.
TENS machines are easy to operate and have minimal risks, especially when compared to medication for pain and surgery. It also works on various kinds of pain. To use it, attach the electrode pads to clean the skin at the back of the neck. Next, adjust the settings and set a timer. To avoid adverse events, consult a healthcare provider before using a TENS unit for neck pain. Those interested in TENS therapy may consider the iTENS.
