Transcutaneous Electrical Nerve Stimulation (TENS) is a type of pain relief therapy that uses a low-voltage electrical current to block pain or change one's perception of it. The electrical current stimulates nerve cells to block the transmission of pain signals, raising the level of endorphins (the body's natural pain-killing chemicals). The intensity, frequency, and duration of the pulses can be adjusted to the user's comfort level. Functional Electrical Stimulation (FES) is another treatment that uses electrical impulses to activate specific muscles and nerves, improving muscle function and movement. While TENS and FES are effective for many, it is important to consult a healthcare provider to determine the best treatment option for your needs.

What You'll Learn

Load batteries into the device
Loading batteries into the BodyMed TENS/EMS/Massager Combo unit is a straightforward process. Firstly, you will need to purchase the correct batteries for the device. The BodyMed TENS/EMS/Massager Combo unit requires two AA batteries, so ensure you have these on hand before beginning.
Once you have the batteries, locate the battery compartment of the device. This is usually found on the underside or back of the unit and will have a small door or flap that opens to reveal the battery housing. Open this door to access the battery compartment.
Next, take the two AA batteries and insert them into the battery housing, ensuring they are aligned correctly according to the polarity indicators (+ and - symbols) within the compartment. Make sure the batteries are securely in place and that the connections are clean and free of debris.
After inserting the batteries, close the battery compartment door securely. You should now be ready to turn on the device and begin using it as per the instructions provided with your BodyMed TENS/EMS/Massager Combo unit.
It is important to note that the BodyMed TENS/EMS/Massager Combo unit is also available in a rechargeable model. If you have this version, you will not need to load batteries, but rather charge the device using the provided charging cable before use.

Place the electrodes on the treatment area
When placing the electrodes on the treatment area, it is important to follow the instructions in the manual of your BodyMed electrical stimulator. Before placing the electrodes on the skin, ensure the skin is clean and dry. If the area is hairy, it is recommended to trim the hair with scissors or clippers, but do not shave, as this can cause micro-abrasions that will make the stimulation uncomfortable.
The electrodes should be placed on the treatment area before turning on the device. If you are using self-adhesive electrodes, simply place them on your skin. If your skin is sensitive, consider using hypoallergenic electrodes, which have a thicker gel layer that makes stimulation more comfortable and typically lasts longer. If you are using carbon flex electrodes, wet the side that will touch your skin and secure them with Velcro straps.
For wrist and finger extension and flexion, place one electrode just above the wrist on the finger extensor motor point, and the other further up the forearm on the tendinous part. For the bicep muscle, place both electrodes on the mid-upper arm. To stimulate the forearm, place one electrode on the fleshy part below the elbow joint, and the other on the flexor surface of the forearm near the elbow.
It is important to consult a physician or healthcare professional before using an electrical stimulator and to ensure that the gel on the electrodes is not dried out.

Turn the device on
To turn on the BodyMed TENS/EMS/Massager Combo device, follow these steps:
First, load the batteries into the device. Make sure you are using fresh batteries and that they are inserted correctly, following the polarities indicated in the battery compartment. Once the batteries are in place, you can proceed to the next step.
Now, place the electrodes on the treatment area. Refer to the instruction manual for the correct placement of the electrodes on the specific body part you intend to treat. The electrodes are typically self-adhesive and should be applied directly to the skin, in close proximity to the muscles you wish to stimulate.
With the electrodes in place, you are now ready to turn on the device. Locate the power button, which is usually clearly marked, and press it to turn on the device. You should see some indicator lights or a display screen showing that the device is powered on and operational.
At this point, you will need to select the desired treatment mode: TENS (Transcutaneous Electrical Nerve Stimulation), EMS (Electronic Muscle Stimulation), or Massage. Each mode offers different benefits, so choose the one that best suits your needs. For example, TENS can help with pain management, EMS directly stimulates muscles, and massage mode provides a soothing experience.
After selecting the treatment mode, you can then choose the specific treatment program that addresses your particular needs. The device offers various programs tailored to target sore muscles and joints, improve blood circulation, or promote relaxation. Each program allows you to control the intensity, frequency, and pulse width of the electrical impulses.

Select the treatment mode
The BodyMed TENS/EMS/Massager Combo is a dual-channel output TENS, EMS, and Massage stimulator. Its three basic functions include Transcutaneous Electrical Nerve Stimulation (TENS), Electronic Muscle Stimulation (EMS), and Massage.
To select the treatment mode, first, load the batteries into the TENS/EMS/Massager unit. Then, place the electrodes on the treatment area as shown in the instruction manual. Next, turn on the electrotherapy device.
Now, you can select the treatment mode from TENS, EMS, or Massager. TENS supports the relief of sore muscles and joints. High-frequency TENS currents activate pain-inhibiting mechanisms in the nervous system, while low-frequency TENS currents facilitate the release of endorphins. EMS sends electronic pulses to the treatment area, providing direct comfort for sore muscles.
After selecting the treatment mode, you will need to select the treatment program and set the treatment program parameters before starting the treatment. The output intensity can be adjusted during treatment using the [+] and [-] buttons.

Adjust the intensity
Adjusting the intensity of electrical stimulation is a crucial aspect of optimising treatment outcomes and ensuring patient comfort. Here are some detailed instructions on how to adjust the intensity of the BodyMed electrical stimulator:
Understanding the Basics of Electrical Stimulation:
Before adjusting the intensity, it's important to understand how electrical stimulation works. Electrical stimulation, also known as e-stim, involves sending electrical impulses through the skin to target nerves and muscles. This stimulation can provide various benefits, such as pain relief, tissue repair, and muscle strengthening.
Assessing Individual Needs:
The intensity of electrical stimulation may vary depending on the patient's needs and their response to the treatment. It's important to consult with a healthcare provider or physical therapist to determine the appropriate intensity level for each individual. They will assess factors such as the patient's condition, tolerance, and treatment goals.
Starting with Lower Intensities:
When beginning electrical stimulation treatment, it's generally recommended to start with lower intensities. This allows the patient to gradually adjust to the sensation and minimise any discomfort. The intensity can then be slowly increased until it feels strong but comfortable for the patient.
Adjusting Intensity Settings:
The specific steps to adjust the intensity on the BodyMed electrical stimulator may vary depending on the device model. However, most devices allow users to control the intensity, frequency, and duration of the electrical impulses. Refer to the device's user manual or instructions for detailed guidance on adjusting the intensity settings.
Monitoring Patient Comfort:
Throughout the treatment, it's essential to monitor the patient's comfort level. If the patient experiences any discomfort or unpleasant sensations, the intensity should be adjusted accordingly. It's important to note that electrical stimulation should not cause pain. If pain occurs, the treatment should be stopped, and a healthcare provider should be consulted.
Regularly Reassessing Intensity Levels:
As the patient undergoes treatment, their muscles may strengthen, and their nerves may adapt to the stimulation. Therefore, it's important to regularly reassess the intensity level and make adjustments as needed. Working closely with a healthcare provider or physical therapist will ensure optimal treatment outcomes and minimise any potential risks or side effects.
