Everything You Need to Know About TENS Units

What is a TENS unit?

TENS stands for ‘Transcutaneous Electrical Nerve Stimulation’. It is a method in which mild electrical current is useful to relieve pain. A TENS unit is a compact device that operates via the battery. It has two or more leads, and each connects to sticky pads, also known as electrodes, at the end. 

How does a TENS unit work?

You can use these lightweight units whether you’re sitting around or are on the move. They are so convenient that you can hold them in your hand, put them in a pocket, and simply clip it to a belt. 

You can also use Shophysio’s TENS unit for as long as you like throughout the day. However, we recommend not using them while driving, during a bath or shower, and while you operate any machinery. You should consult a doctor if you’re unsure about whether they’re safe for you to use or not.

A TENS unit is very straightforward to operate. Simply attach the electrodes to your skin and switch on the unit. Once powered on, a TENS unit delivers small electrical impulses to the affected region of the body, causing a tingling sensation.

A TENS’ electrical pulses tend to interrupt and reduce the pain signal transmitted to the spinal cord and nervous system. This may relax your muscles and help relieve pain. These electrical impulses may also cause enough stimulation to produce endorphins, which are natural painkillers produced by your body. 

Tips for using TENS Units

  • Always make sure that the simulator is off before you attach the electrodes to your skin. 
  • Position these pads at least an inch apart on either side of the pain region. 
  • The TENS unit has a dial or displayed options on the handheld device to select the strength for different treatments. 
  • Always start with a slow setting and gradually dial the intensity up. 
  • Ensure the tingling sensation feels comfortable if you feel slight pain then reduce the strength of electrical pulses.
  • Always switch off the TENS unit before you take the electrodes off your skin. 

Types of TENS Units

Many TENS units are easy to use mobile devices. They come in many models to suit everyone’s needs, including wireless electrotherapy devices and handheld stimulators. You can also get medical-grade combo devices using electrotherapy and ultrasound for pain relief.

Which Professionals Can Use A TENS unit?

Whether you are a chiropractor or a physical therapist, you can use our TENS units with ease on your patients. They are the best form of therapy to help your clients heal faster. Chiropractors have always had the option to utilize alternate therapies that complement their methods. Therefore, a TENS unit can reduce pain and inflammation on injuries, and for muscles joints in a very effective manner. 

Similarly, a physical therapist can use his traditional methods to address back issues, and other muscle related problems and injuries, using a TENS unit to achieve this goal faster than using other methods. 

Places of application on the body

You can use the TENS unit on any pain affected region of your body. However, you should never place the pads over the following areas; neck, mouth, eyes, temples, chest and upper back (simultaneously), genitals, any numb areas, broken or irritated skin, and varicose veins. 

Do I need a Doctor to use a TENS Device?

Generally, you do not need to seek a doctor’s advice while using a TENS unit. However, if you feel that your pain is not getting any better, or has maybe worsened, it is advisable to seek doctor’s help. In the case of pregnancy, you must always ask your doctor before using a TENS unit, or if you have any underlying health issues you may be concerned about (heart problems and such).

Additionally, always read the instruction manual by the manufacturer for the full advice. 

How to Choose the right TENS Device

There are five main things you must look for when it comes to choosing a TENS device. These include:

  • If it has appropriate power levels that are suitable for your treatment needs. 
  • It must have a lithium-ion battery because it increases the duration of treatments, plus it will save money on having to change batteries. 
  • The more options a TENS device has for electric pulses, the better it is.
  • Always choose a TENS device offering you good TENS pads life between changes. 
  • Always consider providers like Shophysio as an excellent option to provide you after-sale customer service. Many other retailers don’t include this service - it’s reassuring to have it included with your TENS device.

Accessories for a TENS Device

It is always a good idea to consider what accessories come with your TENS device. You must also check the duration each accessory lasts, and how frequently it needs replacing. Some of the accessories to consider are: 

Replacement Pads

Electrode pads are the most important of all accessories. Your TENS device cannot operate without these. These pads have an adhesive surface, which enables them to stick to your skin. That is how these electrodes conduct electric pulses to the nerve bundles underneath the skin region they are attached to. 

types-of-electrodes

All TENS devices have different designs, and each of these designs is best suited for specific tasks. Therefore, you must carefully check that you are buying the replacement pads suitable for the therapy you need. We sell electrodes here.

Additionally, some types of pads expire after so many applications. You must know when to change these pads; this is important for the effectiveness of your TENS device. 

Wires and Batteries

Most of our TENS devices come with lithium ION batteries. In case you need to replace these batteries, always ensure that you have the appropriate battery type. A wrong one can damage your TENS unit. Similarly, keep your wires wrapped securely. Do not use any damaged wiring because it is both a safety hazard for you and the TENS unit. Ensure you dispose of any old batteries in the correct way - as recommended by the battery manufacturer.

Check the manufacturer’s manual for details on your wires and batteries.
