IMS Treatment in Mission (Intramuscular Stimulation)
Our IMS Treatment at Legend Physio Mission is built around one thing — you. Whether you are living with deep muscle tightness that won’t loosen up, chronic pain that lingers long after an injury should have healed, or nerve-related tension that has never fully responded to massage or stretching, our team is ready to help. Using fine, sterile needles inserted directly into the problem tissue, IMS works at the source — releasing what is locked, calming what is overactive, and giving your body the reset it needs to genuinely heal.
What Is IMS Therapy and Why Does It Matter?
Intramuscular Stimulation — commonly called IMS or dry needling — is a clinically grounded, evidence-informed treatment that targets dysfunctional muscle tissue using thin acupuncture-style needles. Unlike acupuncture, which follows traditional energy meridians, IMS is rooted in neurophysiology. It focuses specifically on shortened, irritated muscles and the hypersensitive nerve endings that are causing them to stay locked in a cycle of tension and pain.
When a muscle is chronically tight, it is rarely just a muscular problem. In most cases, the underlying driver is nerve irritation — a sensitized nerve root that keeps the muscle fibre in a constant state of contraction. Conventional treatments like massage or stretching can offer temporary relief, but they often cannot reach deep enough to interrupt that nerve-muscle feedback loop.
By placing a needle directly into the affected muscle band, the therapist triggers a brief involuntary twitch response. That twitch is significant — it signals a neurological reset. The muscle releases, blood flow increases to the area, and the nervous system begins to calm down. Over a course of sessions, this leads to lasting relief rather than temporary comfort.

How IMS Therapy Works
Releases Chronically Contracted Muscle Tissue
The needle triggers an involuntary twitch that resets tight muscle tissue to its natural resting length — something stretching alone can’t achieve.Breaks the Nerve-Pain Feedback Loop
IMS stimulates sensitized nerve endings, disrupting the neurological cycle that keeps muscles locked in a guarded, painful state.Restores Blood Flow to Starved Tissue
Tight muscles cut off their own circulation. IMS releases that tension, flooding the area with oxygen and nutrients needed for real recovery.Drives Deep Tissue Repair
By prompting a controlled healing response, IMS sends repair cells and growth factors directly to damaged tissue — not just symptom relief, but structural rehabilitation.Calms Overactive Nerve Endings
Chronic pain lowers your pain threshold over time. IMS desensitizes hypersensitive nerve pathways, restoring a normal, functional response to movement.Conditions Treated With IMS Therapy in Mission
Our Mission physiotherapy clinic uses IMS to treat a wide range of musculoskeletal and nerve-related conditions. Below are some of the most common presentations we see and effectively treat.
Temporomandibular Jaw Disorder (TMJ)
Symptoms
- Pain or aching in the jaw, face, or temples
- Clicking, popping, or locking of the jaw joint
- Headaches concentrated at the base of the skull
- Difficulty fully opening the mouth or chewing comfortably
TMJ dysfunction often involves a combination of joint irritation and chronically overworked jaw muscles — particularly the masseter and pterygoid muscles — that stay in a state of constant contraction. IMS releases the deep muscular tension around the jaw and neck, reduces referred pain patterns that radiate into the head, and gives the joint the space it needs to move freely and without discomfort.
Tennis Elbow (Lateral Epicondylitis)
Symptoms
- Pain on the outer side of the elbow, aggravated by gripping
- Weakness when holding objects, twisting a key, or shaking hands
- Tenderness just above the elbow joint
- Discomfort that builds gradually with repetitive hand and wrist activity
Tennis elbow is driven far more often by chronic muscle guarding and fascial restriction than by acute tendon damage alone. The forearm extensor muscles — locked tight from repetitive loading — pull constantly on the lateral epicondyle and prevent the tendon from recovering.
Rotator Cuff Injuries
Symptoms
- Dull ache deep in the shoulder, particularly at night
- Pain when reaching overhead or behind the back
- Weakness and fatigue with lifting tasks
- Difficulty sleeping on the affected side
Rotator cuff problems are not just about the tendon. The nearby muscles—like the infraspinatus, supraspinatus, and subscapularis—often become tight and stop working properly. This affects how the shoulder moves and puts extra strain on the injured area.
IMS helps by treating these deep muscles, relaxing tight spots, improving movement, and reducing stress on the tendon so it can heal better.
Shoulder Pain and Frozen Shoulder
Symptoms
- Progressive stiffness that limits arm movement in all directions
- Deep, diffuse aching in the shoulder joint
- Pain that disrupts sleep and limits daily tasks
- Pain that disrupts sleep and limits daily tasks
Frozen shoulder involves both joint capsule changes and significant muscular guarding that compounds over time. IMS addresses the muscular component directly — releasing the peri-scapular and rotator cuff muscles that have tightened in response to pain and disuse, improving joint mobility, and helping patients regain comfortable shoulder movement much sooner than passive stretching alone would allow.
Hip Osteoarthritis
Symptoms
- Stiffness and aching in the groin, hip, or outer thigh
- Reduced range of motion, especially with rotation
- Pain that builds with prolonged walking or sitting
- A sense of grinding or catching in the hip joint
Osteoarthritis creates a ripple effect in the surrounding musculature. The hip flexors, glutes, and deep rotators tighten in response to joint irritation, increasing compressive load on a sensitive joint. IMS targets these compensating muscles, reducing tension, improving load distribution, and making movement more comfortable and fluid.
Tension Headaches and Cervicogenic Headaches
Symptoms
- Headaches that begin at the base of the skull and spread forward
- Neck stiffness accompanying head pain
- Sensitivity across the scalp or behind the eyes
- Headaches triggered or worsened by poor posture or prolonged desk work
Many chronic headaches actually start in the neck, not the head. Muscles at the base of the skull, along with the upper trapezius and levator scapulae, can become tight and develop trigger points that send pain into the head. IMS works by targeting and releasing these tight spots, helping treat the root cause of the headache and providing longer-lasting relief than medication alone.
Low Back Pain
Symptoms
- Deep aching or sharp pain across the lower or mid back
- Morning stiffness that eases slowly through the day
- Pain that refers into the glutes, hips, or down one leg
- Muscle spasm that restricts bending and twisting
Deep muscles in the spine can become tight and keep pulling on nerves, causing ongoing pain even after the injury heals.
IMS treatment reaches these deep muscles, helps them relax, and breaks the pain cycle so your back can move freely again.

Yes. IMS is a safe, well-researched technique practiced widely across physiotherapy clinics throughout Canada. When performed by a trained and certified physiotherapist, the risk of adverse effects is very low. The needles used are fine, sterile, and single-use.
What patients typically notice after a session:
What patients typically notice after a session:
- A dull, deep ache or mild muscle soreness in the treated area for 24 to 48 hours
- A feeling of release or lightness in muscles that were previously tight
- Occasionally, brief fatigue as the nervous system recalibrates
The post-session soreness is a normal and positive sign — it indicates that the treatment has engaged the tissue and initiated a genuine healing response. Your physiotherapist will guide you through what to expect and adjust your plan based on how your body responds.

FAQs
Do I need a referral to book IMS treatment in Mission?
In most cases, no referral is required — you can book directly at Legend Physio Mission. That said, some extended health plans may request a physician’s referral for reimbursement purposes. We recommend confirming with your insurer beforehand.
How quickly will I notice results?
Many patients feel a meaningful difference in muscle tightness and pain levels within 3 to 5 sessions. Results depend on how long the condition has been present, its complexity, and how your body responds to treatment — but steady, progressive improvement is the norm.
Does the IMS treatment hurt?
You will typically feel a brief, deep ache or a quick muscle twitch when the needle reaches the target tissue. That sensation is actually a sign the treatment is working. Discomfort is short-lived and most patients find the sessions very manageable.
Can IMS be combined with other physiotherapy treatments?
Absolutely — and it usually works best that way. Our Mission team regularly integrates IMS with manual therapy, corrective exercise, and rehabilitation programs to ensure your recovery is comprehensive and lasting.
Is IMS suitable for people with needle anxiety?
Many patients with mild needle anxiety find IMS much more tolerable than they expected. The needles are extremely fine and are not injecting anything into your body. Our physiotherapists take time to walk you through the process, and your comfort is always the priority.
How long does an IMS session take?
Most sessions run between 30 and 60 minutes, depending on the number of areas being treated and whether IMS is combined with additional physiotherapy within the same appointment.
