TENS Therapy

What Is TENS Therapy?

TENS stands for Transcutaneous Electrical Nerve Stimulation. It is a popular and effective non-invasive method used to manage both acute and chronic pain. TENS involves the use of a small, battery-operated device that delivers low-voltage electrical currents through electrodes placed on the skin.

Unlike other electrical therapies that focus on muscle contraction, TENS is specifically designed to target the sensory nerves. It provides a safe, drug-free way to "scramble" pain signals before they reach the brain, giving you immediate relief from various types of discomfort.
 

How Does It Work?

TENS therapy works through two primary scientific mechanisms:

1. The Gate Control Theory: The electrical pulses stimulate the sensory nerves that carry "touch" and "pressure" signals. These signals travel faster than pain signals, effectively "closing the gate" in the spinal cord and preventing the pain message from reaching the brain.

2. Endorphin Release: At specific low frequencies, TENS encourages the body to produce its own natural painkillers, known as endorphins. These chemicals act like natural morphine to improve your mood and lower your pain perception.

3. Circulation Boost: The gentle tingling sensation encourages blood flow to the local area, which helps in flushing out inflammatory chemicals.
    

What Are The Treatment Parameters?

A TENS session is highly customizable based on the type of pain you are experiencing:

• High-Frequency TENS (50–120 Hz): Used for Acute Pain. This is the "Gate Control" setting that provides fast, short-term relief during movement or activity.

• Low-Frequency TENS (2–5 Hz): Used for Chronic Pain. This setting feels like a "tapping" sensation and is designed to trigger the long-term release of endorphins.

• Intensity: You adjust the "volume" of the current until you feel a strong but comfortable tingling. It should never feel painful or cause sharp muscle contractions.

• Placement: Electrodes are usually placed around the area of pain or over specific nerve pathways.
   

What Are The Benefits?

• Instant Pain Suppression: Provides immediate relief while the device is in use.

• Reduces Dependency on Drugs: Helps patients lower their intake of NSAIDs or opioid painkillers.

• Portable & Convenient: TENS units are small enough to be worn while you go about your daily chores or work.

• User-Controlled: You have the power to adjust the intensity and duration of the treatment based on your comfort level.

• No Side Effects: Unlike oral medications, TENS does not cause drowsiness, stomach upset, or addiction.
   

Conditions Treated By TENS

• Arthritis: Managing joint pain in the knees, hips, and hands.

• Back and Neck Pain: Especially useful for muscle-related stiffness and "Tech Neck."

• Sciatica: Dulling the radiating nerve pain that travels down the leg.

• Period Pain: Highly effective for managing menstrual cramps.

• Post-Surgical Pain: Helping patients manage the initial discomfort after an operation.

• Fibromyalgia: Providing widespread relief for chronic "tender points."
   

How Does The Patient Feel?

• The Experience: You will feel 2 to 4 sticky pads placed on your skin. Once the machine is turned on, you will feel a "buzzy" or "pins and needles" sensation.

• The Sensation: It is often described as a soothing, rhythmic vibration. It should feel like it is "covering" the pain.

• Afterward: Most patients experience a significant "window" of pain relief that can last for several hours after the machine is turned off.
   

The Integrated Plan at Ang Physiotherapy

We use TENS as a vital "pain management" tool within our larger protocols:

1. Home Care Integration: We often recommend TENS units for patients to use at home between their Robotic Decompression sessions to keep pain levels low.

2. Exercise Facilitation: We use TENS during your physical therapy exercises. By numbing the pain, it allows you to perform your Samarth Batch movements more effectively.

3. Combination Therapy: Pairing TENS with Heat Therapy or Laser to attack the pain from multiple angles.
    

Contraindications & Precautions

TENS is very safe, but it MUST NOT be used in the following situations:

• Pacemakers: Do not use if you have an implanted heart device or defibrillator.

• Pregnancy: It is generally avoided over the abdomen or lower back (unless specifically used for labor pain).

• Epilepsy: Should not be used on the neck or head of patients with a history of seizures.

• Broken Skin: Do not place pads over open wounds, rashes, or infected skin.

• Loss of Sensation: If you cannot feel the tingling, you risk turning the intensity too high and causing a skin burn.
