How Dry Needling Works Trigger Points and Muscle Release Explained

 

Introduction
Dry needling Edmonton is a physiotherapy technique often used to address muscle tension, discomfort, and restricted movement. It targets specific points in the muscle known as trigger points. By understanding how dry needling works, patients can make informed decisions about including it as part of their treatment plan.

What Are Trigger Points?

Trigger points are small, sensitive areas in muscle tissue that may feel tight or tender to touch. They can form when muscle fibers remain contracted for a long time or after injury. Trigger points sometimes cause pain in the same spot or refer discomfort to other areas of the body. For example, a trigger point in the shoulder may also cause tension in the neck or upper back.

What is Dry Needling?

Dry needling involves inserting thin, sterile needles directly into trigger points or tight muscle bands. Unlike injections, no medication is used; the needle itself is the active tool. The approach is based on anatomy and physiology, with the goal of releasing tension and improving muscle function.

How Dry Needling Works in the Muscle

When a needle enters a trigger point, several things may occur:

  • Local Twitch Response: The muscle may contract briefly and then relax, which can reduce tightness.

  • Improved Blood Flow: Inserting the needle may encourage circulation in the area, helping the muscle recover.

  • Nervous System Response: The needle can stimulate nerve pathways, which may help lower sensitivity in the affected region.

  • Reduction of Chemical Irritants: Muscles with trigger points often contain higher levels of chemicals linked to pain. Dry needling may help restore balance.

These combined effects can decrease tension and support better movement.

What a Session Looks Like

A typical dry needling session includes:

  1. Assessment – The physiotherapist evaluates symptoms, movement, and muscle tightness.

  2. Needle Placement – Thin needles are inserted into targeted muscles. You may feel a brief prick and sometimes a twitch in the muscle.

  3. During Treatment – Sensations may include mild aching, heaviness, or a quick spasm.

  4. After Treatment – Muscles may feel sore, similar to post-exercise soreness, but this usually fades within a day or two.

Dry Needling and Muscle Release

The release that follows dry needling often makes it easier to move and reduces feelings of stiffness. By relaxing tight muscle bands, the therapy can support posture correction, flexibility, and recovery from injuries.

Dry needling is not a stand-alone treatment in most cases. Physiotherapists often combine it with stretching, exercise therapy, and manual techniques to provide a complete approach to recovery.

Conditions Where Dry Needling is Used

Physiotherapists may recommend dry needling for:

  • Neck and shoulder tightness

  • Lower back pain

  • Sports-related injuries

  • Tension headaches

  • Jaw pain related to TMJ issues

  • Muscle stiffness from repetitive strain

Each treatment plan is individualized based on the person’s condition and goals.

Safety Considerations

Dry needling is considered safe when performed by trained professionals. Needles are single-use and sterile. Common short-term side effects include mild soreness, fatigue, or light bruising. Patients with certain health conditions may need alternative treatments, so it is important to share medical history before starting.

Conclusion

Dry needling works by targeting trigger points to release muscle tension and improve function. Through mechanical and nervous system responses, it helps reduce tightness and restore mobility. When included as part of a physiotherapy plan, dry needling can support recovery and overall muscle health.
