If you have been looking into shockwave treatment for a stubborn tendon or heel problem, you may have seen two different descriptions: “focused” and “radial.” They are not simply stronger and weaker settings on the same machine. They describe different ways of generating and distributing mechanical pressure waves.
That distinction matters, but it does not mean you need to choose a machine before an appointment. The useful starting point is a diagnosis: which tissue is causing the problem, what it needs to tolerate, and whether this treatment belongs in your plan at all.
What is focused shockwave therapy?
A focused shockwave device concentrates acoustic energy into a defined treatment region. Different devices generate that energy in different ways, including electromagnetic, electrohydraulic and piezoelectric systems. The applicator and its settings influence where the energy is concentrated.
Think of “focused” as describing the energy field—not a promise that a treatment will find every source of pain. The clinician still needs to identify the target and choose an appropriate approach. There is no single depth number that accurately describes every focused device and every setting. [1]
How are radial pressure waves different?
Radial devices typically use a moving projectile inside a handpiece to strike an applicator. The resulting pressure wave spreads outward from the contact surface, where its pressure is greatest. This is why the more precise term is radial pressure-wave therapy, even though “radial shockwave” is common in advertising. [1]
The difference is not a judgment about the person receiving treatment or the quality of a clinic. It is a physical distinction. A superficial, broader treatment field and a defined focused treatment region are not interchangeable descriptions. Neither label, on its own, tells you what will work for your particular diagnosis.
Does focused mean better?
Not universally. Professional recommendations distinguish the target tissue and the treatment being considered. They also emphasize clinical assessment rather than a fixed protocol for everyone. Device characteristics, the location of the problem and the intended treatment all matter. [2]
When comparing studies, look for the actual condition, device type and treatment protocol. A finding about one kind of heel pain should not be turned into a promise about a shoulder, a nerve problem or a different device.
For example, a 2024 review combined 16 studies of shockwave treatment versus corticosteroid injections for plantar fasciitis. The pooled results favored shockwave for some pain and function outcomes at three and six months. That comparison is useful, but it does not establish that focused treatment beats radial treatment for every person. [3]
Evidence is not uniform. NICE's guidance for persistent plantar fasciitis describes uncertainty about effectiveness and emphasizes informed consent and outcome review. Its guidance dates to 2009; it should not be mistaken for a new trial or the last word on every newer protocol. [4]
What should happen before treatment?
An evaluation should establish what is being treated and why the proposed approach fits. Bring a clear description of your symptoms, the activities you want to return to, and what you have already tried. Existing reports can be useful; ask the office which ones to bring rather than arranging new tests yourself.
Before agreeing to a course, make sure you understand the alternatives, the goal of treatment and how progress will be judged. A useful goal is concrete: tolerating a particular walk, exercise or daily task—not simply receiving a preset number of sessions.
What should you ask about safety and expectations?
Tell the treating clinician about your health history, medications and implanted devices. Professional recommendations identify restrictions that depend on the treatment field and energy used, including certain tumors, pregnancy-related considerations, implanted cardiac devices and bleeding disorders. Focused high-energy treatment has additional restrictions. This is not a complete screening list and should not be used to clear yourself for treatment. [2]
Local pain and redness were the most frequently reported adverse effects in the plantar-fasciitis review. [3] Discuss what sensations and after-effects are expected for the proposed treatment, what would be unusual, and whom to contact if you are concerned. The plan should also specify when lack of improvement will lead to reassessment.
Discussing options in Manhattan
You do not need to arrive at CityIR with a device choice already made. Bring your questions about the diagnosis, the reason for the recommendation and the role of other care.
