How Does Focused Shockwave Therapy Work?

The PiezoWave2 uses the “piezoelectric principle” based on a high-voltage discharge across a pattern of crystals. Each element expands, generating a pressure pulse that spreads toward a focal region deep into your tissue.
Unlike general massage, MyACT targets tissue at varying depths to compress and manipulate it with pinpoint accuracy. This mechanical stimulus induces adaptation, tissue repair, and regeneration. At a cellular level, shockwave therapy leads to gene expression and biological effects that stimulate healing in tendons, surrounding tissue, and bones.
Biological Effects & Benefits
MyACT goes beyond symptom management to address the root cause of pain through:
Tissue Remodeling
Stimulates collagen production and dissolves calcified fibroblasts.
Increased Circulation
Promotes new vessel in-growth (angiogenesis) and improved blood supply.
Hip Arthroscopy
Reversal of chronic inflammation and release of trigger points.
Reduced Medication
A non-invasive alternative that reduces the need for pain medications.
If you’ve felt nagging joint pain that doesn’t respond to conservative treatment or physical therapy, talk to a pain specialist like Dr. Etelzon.


The PiezoWave2 is effective for a large variety of musculoskeletal conditions, including:
- Tendinopathy: Chronic tendon pain and degeneration.
- Calcification: Dissolution of calcium deposits in soft tissue.
- Scar Tissue: Breaking down fibrosis to improve mobility.
- Bursitis: Reducing inflammation in the bursae.
- Trigger Points: Releasing tight knots in muscles.
PiezoWave2 therapy is a patient-guided process. Because sources of pain are often “referred” (located away from the actual source), your feedback helps define the precise area for treatment.
Setup: A thin coat of coupling gel is applied to help translate acoustic sound waves to the body.
Sensation: You may feel a "deep, dull ache" during the procedure. This confirms the acoustic waves are hitting the correct target tissue.
Duration: A typical session lasts approximately 10-20 minutes.
Frequency: Standard protocols often suggest 2 treatments per week for 3-4 weeks.
Side effects are minimal but may include skin reddening, mild bruising, swelling, or tingling in the treated area for up to 24 hours.

Helped me with my pain! Great bedside manner. Highly recommend this doctor.Anonymous
Dear Dr. Etelzon, thank you again. I am starting to feel more like myself again. I couldn't say the problem is totally gone but a big weight has been lifted. Today I decided to go and do my nails which I did not do for a long time after the incident. I also asked my daughter if we could go to the park. These are things I normally enjoy but forgot about them for a few months now.Anonymous
