Transcutaneous Electrical Nerve Stimulation (TENS) is a non-invasive and drug-free method of pain relief. It works by blocking pain signals sent by the nerves to the brain, providing relief from discomfort. Additionally, TENS can stimulate the release of endorphins. These are the natural painkillers in the body. To use TENS for carpal tunnel, one must first locate the treatment area on the wrist or hand. Then, place the electrodes on the skin and adjust the settings to a comfortable level.
Carpal tunnel syndrome can impact daily life for those who have it. It causes numbness, tingling, and weakness in the hand and wrist, making tasks like typing or holding objects difficult. The pain can be constant and affect concentration and sleep. Seeking treatment and making adjustments can help manage symptoms and improve daily functioning. This article will provide information on the use of TENS therapy for carpal tunnel, including its mechanism of action, proper usage, and details about the condition.
Understanding the Condition Before Conducting TENS for Carpal Tunnel
Carpel tunnel syndrome is a medical condition where the median nerve in the wrist gets compressed. It can cause pain, numbness, and tingling in the fingers and hand. It may also lead to weakness in grip and difficulty holding objects. The condition is often a result of repetitive hand movements like typing or using a mouse. It can also be influenced by health conditions like arthritis.
A TENS for carpal tunnel is a portable device that offers natural pain relief. It consists of a control unit and sets of electrodes. The adhesive round electrode pads send electrical currents to stimulate sensory nerves to reduce painful sensations. There are two types of TENS devices that individuals can use: standard and wireless.
A standard TENS machine has a handheld push-button remote and wires connecting to the electrode pads. On the other hand, a wireless TENS machine utilises Bluetooth technology to connect to a smartphone app. It is popular among individuals who prefer convenient and on-the-go pain management. Nevertheless, both types deliver adequate electrical stimulation.
Symptoms of Carpal Tunnel Syndrome
- Tingling or numbness: the person may feel pins and needles sensations in their fingers or hand.
- Weak hands: grip strength may decrease, making it difficult to hold objects.
- Painful sensations: there may be aching or discomfort in the wrist or hand.
- Difficulty with fine movements: tasks like buttoning a shirt or typing may become challenging.
- Hand clumsiness: dropping things or difficulty coordinating hand movements.
- Wrist stiffness: The wrist may feel stiff, especially in the morning or after rest periods.
- Sensitivity to cold: The affected hand may feel colder than usual.
- Thumb muscle atrophy: the muscles at the base of the thumb may shrink.
Mechanisms of Action Behind TENS for Carpal Tunnel
One of the ways TENS for carpal tunnel operates is through the Gate Control Theory of Pain. This theory suggests that the nervous system can only process a limited amount of sensory information each time. Mild electrical impulses are sent through the skin through TENS, stimulating the nerves. This action “closes the gate” on pain signals travelling to the brain.
Moreover, TENS encourages the release of endorphins, the natural pain-relieving chemicals in the body. These endorphins interact with the pain receptors in the brain, decreasing the sensation of discomfort from carpal tunnel symptoms. They can also improve moods and promote a sense of well-being.
Furthermore, TENS therapy helps boost blood circulation in the affected area. Restricted blood flow can exacerbate carpal tunnel symptoms, leading to increased pain and movement restriction. By enhancing circulation, TENS promotes the delivery of oxygen and nutrients to the affected tissues, aiding their healing process and reducing inflammation. This improved blood flow also helps in easing everyday activities.
Benefits of TENS Treatment
TENS treatment offers several benefits. Firstly, it is a non-invasive and drug-free method of pain relief. It helps eliminate or minimise pain sensations or other discomforts without taking medications or surgeries. Secondly, the therapy device is portable and easy to use. It is more compact and lightweight than the electrotherapy machines in pain clinics.
Thirdly, it provides personalised pain relief through customisable programs. The device has adjustable settings, such as intensity, pulse rate or frequency, and pulse width or duration. Lastly, people can incorporate TENS as an adjunctive treatment option, complementing other therapies or interventions they may be undergoing.
How to Apply TENS for Carpal Tunnel
To effectively apply TENS for carpal tunnel, one should begin by ensuring the TENS device is powered up. Next, the individual should carefully position the sticky pads on the pain area. Before attaching the electrodes, it is essential to ensure the skin is clean and dry, as this helps the pads stick better and conduct electricity properly.
Once the electrodes are in place, the user should switch on the TENS unit. They should begin with a low-intensity setting and gradually increase it until they find a comfortable level. It is necessary to avoid turning the settings too high, as it should never cause pain or discomfort.
Finally, use the TENS therapy for around 15 to 30 minutes per session. Repeat this process several times a day if necessary. Always make sure to follow the instructions provided with the TENS machine carefully. It is also a good idea to consult with a healthcare professional before using TENS therapy for carpal tunnel syndrome.
Electrode Placement Guide
Proper electrode placement is essential for the treatment to be successful. The user should identify the affected area by locating the carpal tunnel. They can find it on the palm side of the wrist, between the wrist crease and the base of the palm. Once identified, they can place the first electrode over this area.
The second electrode should be slightly above the first, towards the forearm. Securely attach both electrodes, ensuring a strong connection to the skin. Generally, electrodes can last up to 20 to 30 applications. It is advisable to replace them regularly to ensure safe and effective use.
Conclusion
Using TENS for carpal tunnel syndrome offers effective pain relief and improved function for individuals experiencing symptoms. By sending electrical impulses through the skin, TENS blocks pain signals from reaching the brain, providing relief. Additionally, it triggers the release of natural pain-relieving chemicals called endorphins, enhancing mood and reducing discomfort. Moreover, TENS therapy boosts blood circulation, aiding tissue healing and reducing inflammation. Whether it is a standard or wireless device, individuals can manage their symptoms conveniently.
Applying TENS therapy for carpal tunnel involves powering up the device, positioning sticky pads on the affected area, and gradually adjusting the intensity to a comfortable level. Users should adhere to a 15 to 30-minute session, several times a day if needed. Proper electrode placement is crucial, with one over the carpal tunnel and the other slightly above the forearm. Regular replacement of electrodes ensures safe and effective treatment.
