Stim Unit: What It Is, How To Use, and Safety Guidelines

A wireless pain relief from iTENS with accessories

In the field of pain management and physical therapy, the use of electrical stimulation has become increasingly popular. The stim unit is an electrical device that is portable and user-friendly. It has gained recognition for its ability to provide pain relief and promote muscle recovery. Accordingly, the electrotherapy device is easy to use. People will only determine the aching area, position electrodes, modify settings, and relax. Moreover, safety guidelines, like cleaning the pain area, are vital.

Whether a person is dealing with acute pain, chronic pain, or recovering from an injury, the medical device is a viable solution. It functions by sending electrical impulses through the electrode pad in the skin. Hence, it is important to know the ins and outs of the device, as well as the safety measures, to ensure optimal results and prevent any potential risks. This article will present more about the tool, how to use it, and the safety precautions.

What is a Stim Unit

A stim unit is used for various therapeutic purposes. The main types are TENS and EMS. They are common in the field of pain management and rehabilitation.  It delivers electrical pulses to specific nerves or muscles in the body. This electric stimulation intends to provide ache alleviation, reduce muscle spasms, or improve muscle function.

The electrical pulses by the device can stream in a High-Frequency (HF) or Low-Frequency (LF). When the device is set to HF, it delivers currents above 50 Hz. This approach utilises the Pain Gate Theory. It suggests that electrical stimulation can close the gates and block pain signals from reaching the brain. This is beneficial in managing acute pain such as muscle pain, labour pain, postoperative pain, and injuries.

On the other hand, when the machine is at LF, it sends impulses below 10 Hz. This triggers the release of endorphins, which are the natural painkillers of the body. Endorphins not only help reduce the perception of aches but also improve overall well-being. This setting is valuable in treating chronic pain. Such condition includes musculoskeletal pain, knee osteoarthritis pain, fibromyalgia, and back aches.

Difference between TENS and EMS

Transcutaneous Electrical Nerve Stimulation (TENS)

  • It relieves aches and manages discomfort.
  • Uses electrical currents to target sensory nerves.
  • Delivers a short burst of pulses to block pain signals to the brain.
  • Promotes relief by stimulating the release of endorphins.
  • The main focus is pain management and perception reduction.

Electrical Muscle Stimulation (EMS)

  • It stimulates muscle contractions and promotes muscle strength and recovery.
  • Uses electrical impulses to target motor nerves and stimulate muscle fibres.
  • Delivers longer, continuous pulses to create muscle contractions.
  • Aims to improve muscle endurance, blood flow, and rehabilitation.
  • The main focus is muscle stimulation, rehabilitation, and physical performance.

How To Use a Stim Unit

The stim unit is a medical device that is easy to use and operate. Begin the therapy by reading the user manual thoroughly to understand overall functionality. Ensure that the machine is charged or has fresh batteries, depending on the power source. Then, determine the treatment area and clean it. Free the skin region from lotions, oils, dirt, and water for proper adhesion.

Attach the electrode patches on the skin based on the recommended placement for the specific condition. Then, turn on the device and navigate the settings accordingly. Users can adjust the frequency, intensity, and duration of the therapy. Some devices offer pre-set programs and modes. Thus, choose the appropriate one. Start with the lowest settings and moderately increase it to the comfort level.

Once the settings are set, start the treatment session by activating the stimulation. Pay attention to any sensations felt during the therapy and adjust the settings as needed. The stimulation must be comfortable and tolerable, not painful. After each session, gently remove the pads from the skin. Clean the machines and store them properly for longevity.

Proper Pad Placement

Proper pad placement is crucial when using a stim machine for various purposes. Firstly, determine the area of the body where to apply the electrode patches. Ensure that the skin area is clean and dry. Secondly, place the pads on the treatment area. Firmly press the pad onto the skin to ensure adhesion.

Pay attention to the recommendable spacing between the electrode pads. This may vary depending on the type of device or specific treatment. Ensure that the pads are evenly spaced and cover the desired treatment area effectively. Smooth out any wrinkles or bubbles that may affect the effectiveness of electrical stimulation.

Safety Precautions When Using a Stim Unit

When using a stim unit, it is important to take certain safety precautions to ensure well-being. Firstly, always read and follow the instructions provided by the manufacturer. Secondly, if a person has serious medical conditions, it is vital to consult a healthcare professional. Before each use, inspect the condition of the device for any signs of damage or wear and tear.

Then, ensure that the skin in the treatment area is clean, dry, and free from cuts. This is to avoid electric shocks and skin irritation. Moreover, follow the advisable pad placement. Incorrect placement may reduce the effectiveness of the therapy or cause discomfort. Furthermore, do not place the electrode pads near the eyes, mouth, throat, head, bony regions, broken skin, and chest.

At the beginning of the session, avoid using high-intensity levels that may cause discomfort or skin irritation. If a person experiences any ache, burning, or excessive discomfort, stop using the device immediately. The advisable duration of the treatment is 15 to 30 minutes. For longer sessions, a 20-minute break is needed before continuing the operation.

Potential Side Effects

Using a stim machine can have potential side effects. These side effects are tolerable and can vary depending on the individual and the intensity of the stimulation. Some common side effects include muscle soreness, skin irritation or redness at the electrode sites, and muscle twitching. This can occur due to the adhesive or excessive intensity settings.

In rare cases, more serious side effects, such as burns or electrical shocks, can occur. This can happen if the machine is not used properly or if there is a malfunction. It is important to follow the instructions carefully or consult with a healthcare professional.

Conclusion

The stim unit can provide various therapeutic benefits. It is a helpful approach in alleviating chronic conditions, acute conditions, or muscle-related problems. The method is less invasive and drug-free, contributing to its popularity and safety. Hence, it utilises electrical pulses through electrode pads to stimulate nerves and muscles in the body. Accordingly, it works in HF to utilise the pain gate and LF to trigger the production or release of endorphins.

There are two popular types of stim devices, the TENS and EMS. TENS focuses on managing aches, while EMS centers on muscle rehabilitation and endurance. The tool is a beneficial approach to many as it is easy to use and operate. This allows people to have accessible pain management and muscle relaxation without the need for frequent assistance from a professional. Nevertheless, it is crucial to note the safety precautions to eliminate any adverse effects.
