Kari Napoli, L.Ac. | Energy Matters Acupuncture & Qigong | Oakland, CA

There is a category of pain that resists almost everything thrown at it. The muscle that stays locked despite massage, stretching, and rest. The shoulder that aches regardless of how much foam rolling gets done. The neck that releases briefly and then returns to the same tight, painful pattern it has held for months. This is myofascial pain — pain driven by trigger points, the hyperirritable nodules in taut muscle bands that generate both local tenderness and referred pain patterns throughout the body.

Dry needling is the most direct and most effective available intervention for this category of pain. A fine needle inserted precisely into a trigger point produces an involuntary twitch response — the muscle's local electrical discharge — that deactivates the trigger point, restores normal muscle fiber length, and interrupts the neurological feedback loop that has been maintaining the pain pattern. The results are often immediate and, with a complete course of treatment, durable.

Kari Napoli, L.Ac. is a Certified Dry Needling provider at Energy Matters Acupuncture in Oakland. Her certification represents specific post-graduate training in trigger point anatomy, dry needling technique, and the clinical protocols that distinguish systematic dry needling from general acupuncture. She has integrated dry needling into her orthopedic acupuncture practice for 17 years, applying it as one component of a comprehensive musculoskeletal assessment and treatment approach.

What Dry Needling Is — The Clinical Mechanism

Dry needling targets myofascial trigger points — defined by the foundational research of Janet Travell and David Simons as hyperirritable spots in skeletal muscle associated with hypersensitive palpable nodules in taut bands. The trigger point is not simply a tight muscle fiber. It is a site of sustained abnormal electrical activity, metabolic distress, and sensitized nociceptors — a local zone of dysfunction that generates both the aching, referred pain that patients describe and the motor inhibition that reduces strength and coordination in the affected muscle.

When a needle contacts a trigger point, it produces a local twitch response — a brief involuntary contraction of the taut band. This twitch response is both diagnostic, confirming that the needle has reached the trigger point, and therapeutic. Research has documented that the local twitch response is associated with normalization of the abnormal electrical activity at the trigger point, reduction in the sensitizing chemicals present in the local tissue, and restoration of normal muscle fiber length. The pain often decreases significantly in the minutes following the twitch response.

The term 'dry needling' distinguishes this technique from 'wet needling,' in which a substance is injected into the tissue. Dry needling uses a solid needle — identical to an acupuncture needle — with no injection. In California, only licensed acupuncturists and medical doctors are legally permitted to perform dry needling. Physical therapists in many other states perform dry needling with significantly less needle training than a licensed acupuncturist holds.

Dry Needling vs. Acupuncture — What the Distinction Actually Means

The relationship between dry needling and acupuncture is one of the most commonly misunderstood topics in musculoskeletal care. The short version: dry needling is a specific clinical application of needle therapy focused on trigger points, using a Western anatomical framework. Traditional acupuncture is a broader system that uses needles to influence Qi circulation along meridian pathways, addressing the full range of health conditions — not just musculoskeletal pain.

The longer version is more nuanced. Chinese medicine has described trigger point phenomena for centuries under different names — ah shi points, which translate roughly as 'that's it' points, are points of maximal tenderness that correspond precisely to what Western medicine now calls trigger points. The mechanisms described in Chinese medicine for these points — stagnation of Qi and Blood, disruption of local circulation, restriction of normal tissue movement — map closely onto the Western biochemical description of trigger point pathology.

Kari uses both frameworks clinically. For a patient with rotator cuff pain driven by trigger points in the infraspinatus and teres minor, dry needling those specific points directly is the most efficient intervention. For the same patient whose presentation also includes systemic Qi deficiency patterns that are contributing to slow tissue healing, acupuncture points that address those systemic patterns are added to the treatment. The two frameworks are complementary in orthopedic practice, not competing.

What Dry Needling Treats — Conditions and Presentations

Chronic Neck and Shoulder Pain

The upper trapezius, levator scapulae, infraspinatus, and scalene muscles are among the most common sites of active trigger points in the East Bay patient population — driven by hours at a computer, forward head posture, and the accumulated tension of a high-stress lifestyle. Dry needling these muscles produces rapid reductions in pain and restriction that massage and stretching alone rarely achieve, because it addresses the neurological dysfunction at the trigger point rather than working around it.

Low Back Pain and Gluteal Pain

Trigger points in the quadratus lumborum, gluteus medius, gluteus minimus, and piriformis muscles are among the most clinically significant sources of low back and buttock pain — and among the most frequently missed. Gluteus minimus trigger points in particular generate a referred pain pattern down the lateral leg that is indistinguishable from L5 radiculopathy without careful clinical assessment. Dry needling these muscles, combined with Kari's orthopedic assessment to distinguish trigger point pain from true radicular pain, is consistently effective for this presentation.

Hip and Knee Pain

Hip flexor trigger points in the iliopsoas and rectus femoris, IT band-related trigger points in the tensor fasciae latae, and the complex trigger point patterns around the knee that develop from chronic quadriceps and hamstring dysfunction all respond well to dry needling. For the active Oakland and East Bay population — runners, cyclists, hikers, yoga practitioners — these are among the most common presentations Kari works with.

Sports Injuries and Performance Limitations

Myofascial trigger points are a consistent finding in sports injuries, both as primary pain generators and as secondary compensation patterns that develop around the original injury. A shoulder injury produces trigger points in the surrounding musculature; those trigger points then limit range of motion and generate referred pain that outlasts the original tissue healing. Dry needling the trigger point pattern is often the intervention that allows an athlete to complete their recovery after the primary tissue healing has occurred but the pain and restriction persist.

Work-Related Repetitive Strain

Repetitive strain injuries — carpal tunnel syndrome, lateral epicondylitis (tennis elbow), de Quervain's tenosynovitis, and the various upper extremity overuse conditions that develop from occupational demands — consistently involve myofascial trigger point components that contribute to pain and dysfunction beyond the primary tendon or nerve pathology. Dry needling the involved musculature is often the missing piece in treatment plans that have addressed the structural component but have not resolved the myofascial layer.

The Local Twitch Response — What to Expect

Patients who have received dry needling before often know what to expect. For those who haven't, it helps to understand what the local twitch response feels like before experiencing it.

When the needle contacts the trigger point, the taut band produces an involuntary twitch — a brief, sharp contraction that patients often describe as a jump, a grab, or a brief intense ache. It lasts less than a second. It can be startling if unexpected, but it is not dangerous and it is not a sign that something has gone wrong. It is the mechanism by which dry needling produces its effect.

Following the twitch response, the muscle typically softens noticeably. The taut band that was palpable before needling is often difficult to find afterward. The referred pain pattern that the trigger point was generating often diminishes within minutes. Some patients experience temporary local soreness in the treated muscle for 24 to 48 hours following treatment — similar to the soreness after deep tissue work — which resolves without intervention.

Dry Needling Certification — Why It Matters

All licensed acupuncturists in California have extensive needle training — a minimum of 3,000 hours of graduate-level clinical training including substantial needle technique education. Within that foundation, dry needling certification represents additional specialized training focused specifically on trigger point anatomy, needling protocols for different muscle groups, safety considerations for needling in proximity to neurovascular structures, and the clinical integration of dry needling within a comprehensive musculoskeletal assessment.

The practical implication is systematic precision. A certified dry needler has trained specifically in the referred pain patterns of each major muscle group, the exact anatomical location of trigger points within each muscle, the needling angle and depth appropriate for each location, and the clinical reasoning framework for selecting which muscles to needle and in what sequence. This systematic approach produces more consistent and more complete results than applying general needling technique to trigger point locations.

Kari's certification, combined with 17 years of orthopedic acupuncture practice, means she brings both specialized technique and deep clinical experience to every dry needling treatment. She has treated the full range of presentations the East Bay patient population brings — from the straightforward acute muscle strain to the complex chronic pain pattern that has been through multiple treatment approaches without resolution.

Frequently Asked Questions

Does dry needling hurt?

The needle insertion itself is typically minimally felt — the needles used are very fine, comparable in diameter to an acupuncture needle, and significantly thinner than a hypodermic needle. The local twitch response when the trigger point is contacted is a brief intense sensation that most patients describe as a quick cramp or deep ache lasting less than a second. Some patients find the twitch response intense; most find it entirely manageable once they understand what it is and that it is associated with the therapeutic effect. Post-treatment soreness for 24 to 48 hours is common and resolves on its own.

How is this different from the dry needling physical therapists do?

In California, physical therapists are not licensed to perform dry needling — only licensed acupuncturists and medical doctors are legally permitted to do so. In states where physical therapists do perform dry needling, their needle training is typically far less extensive than that of a licensed acupuncturist. Kari's 17 years of clinical experience and dry needling certification represent a depth of needle training and musculoskeletal clinical experience that exceeds most physical therapist dry needling programs.

Can dry needling help if I've already tried everything else?

This is one of the most common presentations Kari sees — patients who have done physical therapy, chiropractic, massage, and injections without achieving lasting resolution. In many of these cases, the myofascial trigger point component of the pain has not been directly addressed. Dry needling treats the trigger point itself, not the symptoms it produces — which is why it often succeeds where approaches targeting the symptoms have not. The honest answer is that it depends on what is actually driving the pain, and Kari's assessment will clarify whether dry needling is likely to be the missing piece.

How many sessions does dry needling require?

For acute presentations with a clear myofascial component, significant improvement often occurs within three to six sessions. For chronic pain patterns with multiple involved muscles and longer duration, a more complete course of eight to twelve sessions is typical. Kari integrates dry needling within a broader treatment plan that includes home care — movement, stretching, and strengthening appropriate to the specific presentation — which shortens overall treatment duration by addressing the factors maintaining the trigger points alongside the direct needling treatment.
