Focused vs. Radial Shockwave Therapy: Why We Invested in the Storz Duolith for Our Patients

If you are dealing with chronic heel pain, stubborn tendonitis, or a joint injury that just won't heal, you have likely come across Shockwave Therapy during your research. It is easily one of the most effective, non-invasive regenerative treatments available today.

However, as shockwave therapy grows in popularity, we receive a lot of questions from our patients here in Marathon about the different types of devices on the market. Whether you live right down the road or are traveling to us from Athens, Edgar, Wausau, or Mosinee, you might hear terms like "radial shockwaves," "focused shockwaves," "softwaves," or "StemWave" and wonder what they all mean and more importantly, which one actually works.

To help clear up the confusion, let’s break down the massive differences between radial and focused shockwaves, and explain why we intentionally invested in the Storz Duolith Focused Shockwave device for our practice.

Radial vs. Focused Shockwave: What’s the Difference?

Many clinics advertise "shockwave therapy," but they are actually using radial pressure wave devices. While both radial and focused therapies use acoustic energy to stimulate healing, they act very differently inside your body.

1. Radial Shockwaves (Surface-Level Pressure)

Radial devices use a pneumatic piston (like a mini-jackhammer) inside a handpiece to hit an applicator, sending a pressure wave into the skin.

• The Wave Shape: The energy is strongest at the surface of your skin and spreads outward like a cone, losing strength the deeper it goes.

• Best Used For: Superficial, broad areas of muscle tightness, myofascial trigger points, and general soft tissue tightness.

• Depth: It only penetrates about 1 to 3 cm deep.

2. Focused Shockwaves (Deep, Targeted Healing)

True focused shockwaves do not rely on a mechanical hit. Instead, they use electromagnetic or electrohydraulic energy to create a true acoustic shockwave that travels faster than the speed of sound.

• The Wave Shape: The energy is perfectly funneled into a pinpoint, laser-like beam. It bypasses the surface of the skin entirely and drops its maximum healing energy at a precise depth inside the tissue.

• Best Used For: Deep joint issues, calcific tendinitis, severe plantar fasciitis, bone spurs, and insertional ligament injuries.

• Depth: It penetrates deeply—up to 10 to 12 cm beneath the skin—without damaging the surface tissue.

Why Our Storz Duolith Device is Different

If you look into alternative focused devices, you might see brands like StemWave mentioned. StemWave is an electrohydraulic focused device, which uses a high-voltage spark in water to create a broader pool of acoustic energy.

At our clinic, we chose the Storz Duolith, which utilizes premier electromagnetic technology. Here is why that matters for your recovery:

• Pinpoint Laser Precision: Unlike electrohydraulic waves that have a slightly wider energy spread, the Storz Duolith functions like an ultra-precise laser. If you have a highly localized injury—like calcific tendinitis in the shoulder or a specific tear in the plantar fascia—we can target the exact millimeter of damaged tissue without irritating the surrounding healthy area.

• Unrivaled Comfort and Control: Because the Storz Duolith allows us to finely tune the energy steps directly on the handpiece, we can scale your treatment up safely. You feel a deep, localized tapping or dull ache where the tissue needs healing, rather than an intense, scattered sting on the skin.

• The Gold Standard of Medical Research: Storz Medical is the global benchmark for Extracorporeal Shockwave Therapy (ESWT). Our Duolith device carries rigorous clinical evidence and FDA clearances, meaning your treatment is backed by the highest standards of peer-reviewed medical literature. It isn't just a therapeutic massager—it is a powerful clinical tool.

Worth the Drive: Advanced Healing in Marathon, WI

We regularly welcome patients who travel anywhere from 20 minutes to over 2 hours from all corners of Central Wisconsin and the Northwoods to access our advanced technology. They make the trip because true focused shockwave therapy is highly specialized and difficult to find.

Because the Storz Duolith is non-invasive and requires no downtime, patients find it incredibly easy to drive in from towns like Athens, Edgar, Wausau, and Mosinee for a quick session before safely driving themselves back home.

If you are tired of living with chronic pain and want to see if focused shockwave therapy is the missing piece to your recovery, we are here to make your trip worthwhile.

Frequently Asked Questions About Focused Shockwave Therapy

Because we treat patients from all over Marathon County and regions over two hours away, we want to make your travel planning as seamless as possible. Here are the answers to the most common questions we get about the Storz Duolith:

How many shockwave therapy sessions will I need?

Most chronic conditions require a series of 4 to 6 sessions, spaced roughly one week apart. Some complex or long-standing injuries may require more treatments. Because the treatment stimulates a cellular healing response that continues over time, many patients notice significant relief after just their second or third visit.

How long does a Storz Duolith treatment appointment last?

The shockwave application itself takes only 10 to 15 minutes per area. When you factor in check-in, a quick assessment, and setting up the device, your entire appointment will typically last about 15-30 minutes.

Is there any downtime after focused shockwave therapy?

No, there is zero downtime. Because the Storz Duolith uses precise acoustic energy instead of surgery or injections, there is no structural damage to the skin or tissue. You can immediately get back into your car and safely drive up to two hours back home. We simply recommend avoiding high-impact, strenuous exercise for 24 to 48 hours after your session to let the treated tissue rest.

Does focused shockwave therapy hurt?

Unlike older generations of shockwave machines or some radial devices that can feel sharp or stinging, the Storz Duolith is highly tolerated. You will feel a deep, dull, rhythmic ache or thumping over the injured area. This sensation lets us know we have successfully located the damaged tissue. We can adjust the energy levels on the handpiece in real-time to ensure the treatment is completely manageable for you.

Do I need a referral to get shockwave therapy at your Marathon, WI clinic?

No medical referral is necessary to schedule an evaluation at our practice. Whether you are seeking a second opinion or are driving a long distance for a definitive solution to chronic pain, you can contact us directly to map out your treatment plan.
