At Adelaide West Physiotherapy, we specialize in evidence-based, advanced treatments for chronic musculoskeletal pain. One of our most effective solutions is Gunn Intramuscular Stimulation (IMS)—a modern, targeted approach to neuromuscular therapy that helps restore normal function and eliminate pain at its root. Whether you’re experiencing long-standing back pain, repetitive strain, or nerve-related dysfunction, IMS therapy may provide the long-term relief you’ve been searching for.
What Is Gunn Intramuscular Stimulation (IMS)?
Gunn IMS is a needling technique developed by Dr. Chan Gunn in British Columbia. It targets tight or shortened muscles that are compressing or irritating nerves. Unlike traditional acupuncture, which is based on Eastern medicine principles, Gunn IMS is rooted in Western medical science and focuses on diagnosing and treating the underlying cause of pain—usually nerve dysfunction resulting from muscle shortening.
During a session, fine, sterile needles are inserted into affected muscles. This causes a twitch or cramping response, which helps relax the muscle, desensitize the nerve, and restore normal function. No medication is injected, and the treatment is highly individualized based on your specific condition and response.

Conditions Treated With IMS Therapy
IMS therapy is particularly effective for chronic pain that doesn’t respond well to standard physiotherapy treatments. It addresses conditions where nerve irritation and muscle shortening coexist—a common root cause of persistent pain.
IMS Therapy May Help With
- Chronic low back pain
- Neck and shoulder tension
- Tennis elbow or golfer’s elbow
- Sciatica or piriformis syndrome
- Tension headaches
- Carpal tunnel-like symptoms
- Hip, knee, or Achilles pain
- Whiplash-associated disorders
- Frozen shoulder
- Repetitive strain injuries
Many of these conditions are diagnosed as “non-specific” in nature. IMS provides a way to identify and treat the actual underlying dysfunction rather than just managing symptoms.
The Science Behind IMS: A Canadian Innovation
Gunn IMS is a proudly Canadian innovation. Developed in Vancouver and now used internationally, the technique is built on the foundation of neuropathic pain—pain caused by a malfunction in the nervous system rather than direct injury.
According to data from the Canadian Pain Task Force, 1 in 5 Canadians lives with chronic pain, often without a clear medical explanation. IMS offers a new perspective on treatment by focusing on nerve-muscle imbalances that traditional scans and diagnostics may miss.
By releasing shortened muscles and restoring nerve function, IMS helps re-establish healthy movement patterns—something particularly vital in our modern, sedentary lifestyles where postural strain is increasingly common.
What to Expect During Your IMS Session
Every IMS session at Adelaide West Physiotherapy starts with a comprehensive assessment. Your physiotherapist will evaluate your posture, movement, pain patterns, and medical history before proceeding.
A typical session may include:
- Identification of nerve-affected muscles
- Explanation of needling points and goals
- Clean, single-use needle insertion
- Localized muscle twitch response
- Post-treatment education and mobility guidance
You may feel muscle soreness or heaviness for 24–48 hours post-treatment—similar to a workout. Most patients report feeling looser and lighter shortly after treatment.
For optimal results, IMS is typically performed once per week over several weeks, depending on your progress.
IMS Therapy vs. Dry Needling vs. Acupuncture
While IMS and dry needling are often used interchangeably, not all dry needling techniques are the same.
| Technique | Approach | Basis |
|---|---|---|
| IMS | Treats nerve-related muscle shortening | Western medicine |
| Dry Needling | Targets trigger points | May vary by practitioner |
| Acupuncture | Based on meridian energy lines | Traditional Chinese medicine |
At Adelaide West Physiotherapy, our therapists are trained in Gunn IMS, which follows a medical model and is supported by rigorous research and safety protocols.

- Up to 90% of chronic low back pain is considered non-specific—meaning the exact source is hard to pinpoint via imaging.
- Research from Canadian physiotherapy associations shows that IMS, when used appropriately, reduces pain intensity and improves mobility in over 70% of patients with neuropathic dysfunction.
