Active Release Technique
Active Release Technique (ART) is a non-invasive, movement-based soft tissue technique designed to locate and treat soft tissue problems. Your physical therapist applies pressure to a tight area while you move it.

Service
Shockwave therapy, also called extracorporeal shockwave therapy (ESWT), was first introduced in 1980 as a non-invasive way to break up kidney stones and gallstones. Today it is commonly used in physical therapy clinics for pain in the muscles, tendons and joints, including acute and chronic sports and overuse injuries, and it offers a non-invasive option for people hoping to avoid surgery or long-term pain medication.
We offer focused shockwave therapy using a PiezoWave² unit at our Irvine clinic. Focused shockwaves concentrate energy on specific points and reach deeper tissues. Radial shockwaves, a different type, spread more widely and mainly reach tissue near the surface.
During treatment, a conducting gel is applied to the skin and a handheld applicator sends acoustic waves to the target tissue. Tendons, ligaments, bone and blood vessel cells respond to this kind of mechanical energy, which may increase local blood flow and support the body's repair process.
Many professional sports teams use shockwave therapy for their athletes, including NBA teams such as the Los Angeles Lakers and LA Clippers, NFL teams such as the Los Angeles Rams and Los Angeles Chargers, and teams in the NHL.
“We’re thrilled to be the first physical therapy clinic in Orange County to offer Shockwave Therapy to our patients.”
Where it is offered: Offered at our Irvine clinic only. Long Beach clients who need this treatment are referred to Irvine.

In your plan of care
Shockwave is not a stand-alone treatment at KOH Physical Therapy Lab. Your physical therapist uses it within a plan of care, usually alongside hands-on treatment and a progressive exercise program, so the treated tissue is loaded and strengthened as it recovers.
It may be considered when tendon or soft tissue pain has lingered, or when earlier care has not been enough. Your therapist decides during your evaluation whether it fits your condition, and screens for reasons it should not be used.
Sessions take place at our Irvine clinic at 9080 Irvine Center Dr. Long Beach clients who may benefit are referred to the Irvine clinic for shockwave sessions.
Benefits

Conditions
The technique
Shockwave therapy uses high-energy acoustic sound waves to reach tissue at different depths. The waves compress and work the tissue, much like a focused, precise deep tissue massage, which can increase circulation and ease pain.
The PiezoWave² delivers mechanical energy as sound waves to the target tissue. Cells in tendons, ligaments, skin, bone, cartilage and blood vessels all respond to this kind of mechanical energy. Your therapist can locate trigger points and deliver focused pulses to the right depth, between about 0.5 millimeters and 3 centimeters depending on the applicator, to support cellular repair by increasing blood flow and reducing pain.
Research
Shockwave therapy is scientifically proven for several conditions, with a high success rate for plantar fasciitis. A 2023 systematic review and meta-analysis found high-quality evidence that shockwave therapy has a large effect on pain and function in plantar fasciitis.
A 2024 systematic review found shockwave therapy to be a safe treatment for plantar fasciitis and more effective than corticosteroid injections at reducing pain and improving foot function at six months. The most common side effects were brief local pain and mild skin redness.
It is also widely used for other tendon conditions, such as tennis elbow and calcific tendonitis of the shoulder. Your physical therapist evaluates your condition to decide whether shockwave is a good fit.
Safety
Shockwave therapy is an extremely safe procedure with few side effects. Some swelling, bruising or tenderness can appear shortly after a session and usually settles within a few days; serious reactions are highly unlikely.
Soreness after treatment is thought to come from the tiny areas of controlled stress the shockwaves create in tissue such as tendon, muscle and bone, which prompt blood flow and cell regeneration. Sensitive areas can feel uncomfortable for a short time afterward.
Your therapist screens you before treatment. If you have neuropathy or hypersensitivity in the area, your therapist decides with you whether shockwave is appropriate.
Men's pelvic health
Low-intensity shockwave therapy (Li-ESWT) is also studied as a treatment for erectile dysfunction. A small handheld applicator delivers low-energy sound waves to penile tissue, with the aim of improving blood flow.
A 2022 review in American Family Physician found mild to moderate improvement with no significant side effects. The American Urological Association considers it investigational, the European Association of Urology says it may be used for mild ED caused by reduced blood flow, and it is not FDA approved specifically for ED. At KOH Physical Therapy Lab it is offered at our Irvine clinic as part of men's pelvic health care.
