Radial Shockwave vs Focused Shockwave: What Patients Should Know
Written by: Bretz Chiropractic Clinic
Shockwave therapy is an umbrella term that can hide an important distinction. Radial pressure-wave devices and focused shockwave devices do not generate or distribute acoustic energy in the same way. Patients comparing clinics should know which technology is actually being offered rather than assuming every machine marketed as shockwave is interchangeable.
Bretz Chiropractic Clinic uses the Chattanooga Intelect RPW 2. It is a radial pressure-wave device, commonly called radial shockwave. It is not a focused shockwave unit.
How radial pressure waves are produced
The Intelect RPW 2 uses pneumatically generated, low-energy acoustic pressure pulses. A projectile inside the handpiece transfers energy to a transmitter placed against the skin. The pressure is greatest near the applicator and spreads through the surrounding tissue.
Chattanooga describes the system as radial pressure-wave technology. Using the more precise term is helpful because it tells the patient what the clinic actually has instead of relying only on the broader shockwave label.
How focused shockwave differs
Focused shockwave systems are designed to concentrate acoustic energy at a selected focal area. They use a different energy field and different generation methods from radial devices. Focused treatment may reach a selected target differently, but that does not mean it is automatically better for every complaint.
A 2026 systematic review comparing radial and focused shockwave therapy for tendinopathy found no clear overall superiority for pain or function, and the certainty of much of the evidence was low or very low. Device type, diagnosis, treatment parameters, comparison treatment, and study quality all matter.
What radial pressure-wave therapy may be considered for
Clinicians may consider radial pressure-wave therapy for selected tendon complaints, myofascial trigger-point findings, or other surrounding soft-tissue problems. At Bretz Clinic, the decision follows an examination. A label such as plantar fasciitis or elbow pain does not automatically mean the modality is appropriate.
The clinic’s radial shockwave therapy page explains the role of the Intelect RPW 2 and the screening that happens before treatment.
What it is not used to claim
Radial pressure-wave therapy does not mechanically decompress the spine. It should not be described as pushing a disc back into place, repairing a herniated disc, or removing pressure from a nerve. In a selected non-surgical disc-care plan, it may be considered only for relevant surrounding soft-tissue findings. Spinal and neurologic findings require their own evaluation.
What a session may feel like
The clinician identifies the treatment area, applies a coupling medium, and moves the handpiece over the selected tissue while the device delivers repeated pulses. The intensity can be adjusted. Patients usually notice tapping or firm pulsing, and some areas may feel tender.
Temporary soreness, redness, or bruising can occur. Tell the clinician if the sensation becomes too uncomfortable or symptoms change. The number and spacing of visits should depend on the diagnosis and response rather than a universal package.
Screening and reasons to use caution
The clinician should review the treatment area, medical history, medicines, and relevant contraindications before starting. Pregnancy, infection in the treatment area, treatment near certain tumors or growth plates, bleeding concerns, and some medicines or medical conditions may affect whether treatment is appropriate. The exact device instructions and the patient’s circumstances guide that decision.
How progress should be judged
Progress is more than whether the area feels different immediately after a session. It may include pain during a relevant activity, tolerance for work or exercise, strength, range of motion, and examination findings. If meaningful improvement is not occurring, the diagnosis and plan should be reconsidered.
Questions to ask a clinic
Ask whether the device is radial or focused, the exact model being used, why it matches your findings, what side effects or precautions apply, and how progress will be measured. A clear answer should describe the technology accurately and should not promise that acoustic pulses will repair tissue or guarantee recovery.

Frequently asked questions
Does Bretz Clinic use focused shockwave therapy?
No. The clinic uses the Chattanooga Intelect RPW 2, which delivers radial pressure waves.
Is radial shockwave always less effective than focused shockwave?
No clear overall superiority has been established for pain or function across tendinopathy studies. Evidence quality, diagnosis, device, protocol, and individual response matter.
Can radial pressure-wave therapy treat a herniated disc?
It does not decompress a disc or nerve. It may be considered only for relevant surrounding soft-tissue findings after examination.
