Rexburg, Idaho – September 22, 2026 -- Patients dealing with muscle tightness or limited range of motion may encounter a treatment called dry needling during physical therapy, a technique explained in a new article from HelloNation featuring insights from Paul Dye of Rexburg Rehabilitation in Rexburg, ID.

A thin needle targets tight muscle areas without injecting anything.

During dry needling, a physical therapist inserts a thin needle into selected muscles or areas linked to pain, tightness, or restricted movement. The needles carry no medication and nothing is injected into the body. Treatment areas are chosen after the therapist reviews symptoms, mobility, strength, and movement patterns, often focusing on trigger points -- sensitive spots within muscles that feel tight or tender under pressure.

Dry needling differs from acupuncture despite similar tools.

Both techniques use thin needles, but acupuncture originates from traditional Chinese medicine and follows a distinct treatment framework. Needling used in rehabilitation instead centers on anatomy, movement, and physical function.

Therapists rarely rely on needling alone.

The technique is typically paired with stretching, strengthening, mobility work, and movement training to address limitations that extend beyond a single session. One variation combines needling with low-level electrical stimulation to reach tissue below the surface, which may be used when muscle knots restrict movement. Another involves controlled needle movement around a tendon, creating a localized, limited inflammatory response and increased blood flow, often followed by strengthening or loading exercises.

Sensations vary widely from patient to patient.

Some people report pressure, aching, muscle twitching, or brief cramping during treatment, along with soreness afterward comparable to post-exercise discomfort. The intensity and duration depend on the technique, treatment area, and individual response.

An evaluation determines whether the technique fits a patient's plan.

Pain and movement restrictions can stem from muscle tension, weakness, joint stiffness, tendon problems, prior injuries, or movement habits. A physical therapy evaluation weighs these factors before deciding how -- or whether -- needling should be incorporated. Therapists also examine how nearby muscles and joints function during everyday activities, not just the specific area where symptoms occur.

Throughout rehabilitation, therapists monitor range of motion, soreness, strength, and functional tolerance to decide whether dry needling should continue as part of the treatment plan or be adjusted.
