Dry Needling vs Exercise in Physiotherapy: Do You Need Both?

Dry needling or exercise: which does your physio actually choose?

Dry needling (often called IMS, or intramuscular stimulation, in BC) targets overactive muscle and resets the tissue. Therapeutic exercise builds load tolerance and restores the capacity that prevents the problem from returning. Most persistent muscle and tendon problems need both in sequence: needling first to bring the tissue to a state where it can be loaded, then exercise to make the gains durable.

When your physiotherapist suggests dry needling, the question of whether to add an exercise program alongside it has a specific answer that depends on what is driving your pain. This post explains how the two tools work, when each is the right first choice, and the research behind combining them.

What dry needling actually does

Dry needling and IMS are used interchangeably in BC physiotherapy practice. Both describe the insertion of a fine monofilament needle into muscle tissue, most often into a trigger point, which is a palpable band within a muscle that is overactive, tender, and sometimes producing pain that refers to another area. The technique is a physiotherapy scope procedure in BC, delivered by physiotherapists who hold post-graduate training in needling.

The needle produces a local twitch response (a brief involuntary contraction of the muscle fibre) which resets the motor endplate at the neuromuscular junction. The chemical environment around an active trigger point contains elevated concentrations of substances associated with pain and inflammation: bradykinin, substance P, and others. The needle disrupts that environment and the muscle's sustained contraction, after which tissue tension and the referred pain associated with the trigger point typically reduce.

This is a different mechanism from acupuncture, which works primarily on pain signal processing at a system level. Dry needling targets a specific mechanical problem in a specific muscle. For a deeper comparison between dry needling and traditional acupuncture, see our posts on dry needling vs acupuncture and IMS vs acupuncture.

The important limit: dry needling does not build capacity. A muscle that needed needling because it was overloaded from a weak hip will return to the same state if the hip weakness is not addressed.

What therapeutic exercise actually does

Exercise prescription is central to physiotherapy practice. When a physiotherapist prescribes exercise, they are building the tissue's ability to accept load: stronger tendons resist overuse breakdown, stronger muscles distribute force away from injured structures, and more controlled movement patterns reduce the repetitive stress that caused the original problem.

For tendinopathy, the evidence for progressive loading is strong. A 2015 randomised controlled trial in the British Journal of Sports Medicine (Beyer et al.) compared heavy slow resistance exercise against eccentric-only exercise for Achilles tendinopathy and found heavy slow resistance superior for pain and function at 12 months. For most tendon problems, loading is the primary treatment.

For muscle-dominated problems, the logic is the same: a quad that doesn't generate enough force to control the knee through single-leg landing will keep stressing the patellofemoral joint regardless of how often the quadriceps' trigger points are needled.

The limit of exercise is that it is harder to execute when the tissue is too irritable to load. A muscle that remains guarded and tender cannot be worked through a progressive resistance program effectively, which is where needling becomes an enabling step rather than a competing one.

What the research says about combining them

A 2017 systematic review in the Archives of Physical Medicine and Rehabilitation (Rodríguez-Mansilla et al.) looked at dry needling for low back pain and found that dry needling plus exercise consistently outperformed either alone, with the combined group showing greater reductions in pain and disability at follow-up.

A 2020 randomised controlled trial published in Pain Medicine (González-Iglesias et al.) compared dry needling alone, exercise alone, and the combination for chronic non-specific neck pain. The combination group had lower pain scores and higher function scores at 6 weeks and at 3-month follow-up compared with either intervention alone.

The clinical logic behind this is straightforward. Dry needling reduces the local muscle overactivity and pain that make loading difficult. Exercise rebuilds the capacity that makes the gains last. The two are complementary rather than competing.

When dry needling alone is enough

For genuinely acute presentations where the problem is muscle spasm after a sudden overload (a pulled hamstring in the acute phase, a neck that seized up after sleeping in an unusual position), needling the affected segment can settle the spasm quickly and restore pain-free movement. If the muscle was healthy before the acute episode and the movement pattern that caused it was isolated, exercise may not be required beyond basic recovery activity.

A single session of dry needling resolving a trigger point that has been causing referred headache for two weeks, with no return of symptoms, is a clean clinical success without adding a loading program.

---

When exercise alone is enough

For de-conditioned tissue that needs loading, where the muscle is not overactive but simply underprepared for the demands being placed on it, exercise is the primary treatment. Patellofemoral pain in a runner who has ramped mileage too fast without adequate hip and quad strength is an exercise problem. A returning runner with plantar fasciitis related to calf weakness is an exercise problem. Needling an underloaded tendon without building the load tolerance behind it addresses nothing.

When both make sense: the common sequence

The case for combining them is strongest when:

• The tissue is reactive enough that loading is difficult or produces a significant flare
• Trigger points are generating referred pain that makes movement assessment misleading
• The patient has been in a pain cycle long enough that guarding has altered their movement pattern

The most common sequence at Launch Rehab: dry needling in the first session or two to reduce the overactive trigger point activity and bring the tissue to a state where loading is possible. Progressive exercise starting once the tissue can accept it, building week over week alongside the ongoing manual and needling work.

The two do not have to follow a strict schedule. Some patients have needling and exercise in the same session once the tissue is more settled. Others continue needling periodically as a maintenance tool while the exercise program runs for months.

Dry needling in physiotherapy in BC: what to expect

Dry needling is a physiotherapy scope procedure when delivered by a physiotherapist who holds the required training. In BC, physiotherapists are regulated by the College of Health and Care Professionals of BC (CHCPBC). The physiotherapist completing the needling must have completed post-graduate IMS training, which is a separate qualification from the basic physiotherapy degree.

At Launch Rehab, IMS and dry needling is delivered by physiotherapists and carries a $5 surcharge on the private physiotherapy session fee when added to a session. ICBC and WorkSafeBC claims follow the physiotherapy billing rules. Extended health plans vary in whether they cover needling under physiotherapy or require it under a separate acupuncture pool; check your plan booklet before booking if this matters to your coverage.

Frequently asked questions

What is the difference between dry needling and IMS?

In BC physiotherapy practice, both terms describe the same procedure: inserting a fine monofilament needle into a muscle trigger point to release it. "IMS" (intramuscular stimulation) is the term used by the system developed at UBC and common in BC; "dry needling" is more common internationally and is increasingly used here as well. At Launch Rehab, the same technique is called either term depending on which physiotherapist trained in which tradition.

How many dry needling sessions do I need?

Most acute trigger point presentations respond in 1 to 4 sessions. Chronic or recurrent trigger points often require more, particularly when an underlying load gap means the trigger point will return without an exercise program alongside. Your physiotherapist can give you a better estimate after the first session, when the tissue response to needling is clearer.

Is dry needling the same as acupuncture?

No. Dry needling targets specific muscle trigger points using a Western anatomy and neuromuscular physiology framework. Traditional acupuncture uses specific meridian points in a system based on traditional Chinese medicine theory. The needles look similar, but the diagnosis, the point selection, and the mechanism are different. Physiotherapists trained in IMS use dry needling; registered acupuncturists use traditional acupuncture. Some physiotherapists also hold acupuncture training and use both systems. See our dry needling vs acupuncture post for a full comparison.

Is it normal to be sore after dry needling?

Yes. A day or two of local muscle soreness after dry needling is common. The twitch response and the needle's disruption of the trigger point produce a brief inflammatory phase that resolves into the release. The soreness is usually less intense than the original pain it is treating. Applying warmth to the area and keeping moving gently helps.

Can dry needling replace exercise for physiotherapy?

In most cases, no. Dry needling changes how an overloaded muscle behaves. It does not build the load tolerance that prevents the problem from returning. For most persistent muscle and tendon problems, exercise is the part of the plan that makes the results durable. The 2017 Archives of Physical Medicine review found the combined approach consistently outperformed either alone.

Is dry needling covered by ICBC or WorkSafeBC?

Dry needling or IMS delivered by a physiotherapist is billed under physiotherapy and covered under ICBC pre-approval in the first 12 weeks, with a $5 surcharge on private physiotherapy sessions. WorkSafeBC follows physiotherapy billing rules. For ICBC claims, no additional approval is needed to add needling to a physiotherapy session. Confirm current coverage with the front desk before your appointment.

What does dry needling feel like?

The needle insertion through skin feels like a pinprick. When the needle reaches the trigger point, most people feel a brief, strong muscle twitch and a local ache or a brief cramp sensation. This passes in a few seconds. After the twitch, many people feel the muscle relax and the referred pain reduce. Some feel immediate improvement in movement range. Soreness in the area typically arrives a few hours later and lasts one to two days.

Does dry needling work for nerve pain?

Dry needling targets muscle trigger points directly. For nerve pain that is coming from a disc, a narrowed canal, or direct nerve compression, dry needling may reduce some of the muscle spasm secondary to the nerve problem, but it does not treat the nerve itself. A physiotherapy assessment to identify the pain source is the appropriate first step for nerve-quality symptoms.
