Wireless Electric Muscle Stimulator: How Does It Work?

Electrical Stimulation (E-Stim) is a form of therapy used to alleviate pain and improve physical functions. The most common types of this therapy are Transcutaneous Electrical Nerve Stimulation (TENS) and Electrical Muscle Stimulation (EMS). TENS targets nerves for pain relief. EMS, on the other hand, stimulates the muscles for strengthening and reconditioning. Wireless electric muscle stimulator transmits stronger currents to stimulate muscle contractions through the electrode pads attached to the skin of the body.

Both of these use electrical pulses but serve different purposes. EMS devices are training tools for athletes and can be found in fitness centres, physical therapy, and rehabilitation clinics. They are also designed and sold for at-home use. Doctors may use this to re-educate their patient’s muscles and help to treat other medical conditions. In this article, you will learn about how wireless EMS works, how to use it and what you use it for.

How Does a Wireless Electric Muscle Stimulator Work?

As mentioned, a wireless electric muscle stimulator machine is a device that uses sticky pads called electrodes that are attached to the skin. Through these, electrical impulses are delivered to the affected area to stimulate the muscles causing them to contract. Hence, repeated contractions help to strengthen the muscles and repair tissues. It also helps improve muscle conditions and functions. 

A central unit controls the pulses. For a handheld device, this is a separate apparatus that connects to the pads via cables. Wireless devices, however, can use a smartphone app and connect via Bluetooth. Through this app, the user sets intensity, duration, and more preferences for their session.

Once the electrical currents start, they stimulate muscles in the targeted area. This can have several effects, such as increasing blood flow, reducing swelling, and exciting muscles. The overall sensation is often relaxing, and you can feel your body recovering during the process. After a session, you should immediately feel the results.

Benefits of EMS Therapy

EMS therapy can help treat injuries and ailments and several benefits may include the following:

  • Reduces muscle pain
  • Increases strength of the muscles
  • Promotes healing of tissues
  • Regains and maintains muscle activity
  • Stimulates the muscular blood flow
  • Enhances rehabilitation of the muscles
  • Reduces joint pain and swelling
  • Prevents the loss of muscle tissue or muscle mass
  • Increases range of motion for tendons or tensed muscles
  • Expedites the healing process of damaged or injured tissues
  • Helps reduce chronic pain
  • Decreases the need for pain medications and their side effects
  • Improves the quality of life for people with long-term symptoms

How to Use Wireless Electric Muscle Stimulator

Before using a wireless electric muscle stimulator, it is important to know the process. Setting the device up properly is crucial to having a productive session. First, ensure you have good pad placement. Electrode pads should go as close to the area you wish to treat as possible while avoiding certain spots as discussed below.

Once the pads are all set up and you are ready, turn the device on. From here you can configure your therapy session and begin. It is generally best to start on a low setting and gradually move to higher intensities as needed.

Have a plan when you start using the EMS. Know when and how long you will use it for. If you finish a session and think you need another, be sure to take a break first before continuing. As you get used to the EMS, you will learn what intensities and durations work best for you. You can configure an ideal therapy session in the app so you always have your settings ready to go.

Safety Precautions

Keep in mind some basic safety precautions when using EMS. There are certain areas where you should not place electrode pads, like wounds, the temples, the spine, and joints. Make sure the pads are not touching each other. Try to keep about a few centimetres between them.

Be careful not to use the device for too long. Excessive use can cause skin irritation and rashes. Turn the device off after 20 to 30 minutes of use, and take a break before using it again. If your skin starts to turn red, try placing the pads in a different location.

Applications of Wireless Electric Muscle Stimulator

A wireless electric muscle stimulator has many applications. Depending on your fitness lifestyle or medical conditions, you may use an EMS in different ways. However, almost anyone is guaranteed to find a use for it. EMS devices can be used for physical therapy to post-workout recovery. For partially or wholly paralyzed people, these units are used for rehabilitation and strengthening muscles.

As mentioned, doctors may also use EMS for patients who require muscle reeducation. EMS devices are also suitable for the relaxation of muscle spasms, increasing the range of motion, and preventing muscle atrophy. Furthermore, it helps to treat medical conditions that are the result of serious injury, stroke or major surgery.

For athletes, an EMS is excellent for muscle recovery after working out. The device helps muscles to relax and recover at a faster rate. This means that their exercise may be more productive with EMS. The EMS units from iTENS Australia are perfect for anyone who wants the benefits of this type of therapy.

EMS therapy is a popular pain relief and injury recovery treatment method. Through electric pulses, it stimulates muscles to increase blood flow, reduce swelling, and relax. EMS is a great way to enhance muscle strength and regains muscle activity. The overall effect leads to a speedier recovery. Wireless electric muscle stimulators are easy to use. Simply connect the electrode pads to the body and turn the device on, using your preferred settings.

The wide array of benefits EMS provides means it is suitable for almost anyone. Whether recovering from an injury or fitting it into your fitness routine, an EMS device greatly enhances the healing process and makes for a more relaxing recovery.
