Radial Extracorporeal Shockwave Therapy (rESWT)is a fast & effective non-surgical method of eliminating or reducing many painful conditions of the musculoskeletal system. rESWT has been shown, in the short term, to have a 56 to 90% success rate in the treatment of soft tissue disorders, including calcific tendinitis of the shoulder, plantar fasciitis, and tennis elbow.(1) Research has also shown excellent success with treatment of heel spurs, achilles tendinitis, rotator cuff tendinitis, patellar tendinitis. (See the included list of research papers for details of treatments.)
How Does It Work?
rESWT uses a pneumatic generator to physically deliver a shockwave through the skin, into the body. Think of it like a tiny jackhammer striking the skin to create a shockwave. The high-energy impact waves are transmitted through the surface of the skin and spread radially (spherically) into the body. To start, the treatment relieves pain by producing an analgesic effect, over several treatments an inflammatory response begins & the body responds with increased metabolic activity surrounding the area of the pain which stimulates and accelerates the healing process.(2)
“Until recently, treatment options for chronic tendinitis have been limited to NSAIDS, stretching exercises and avoidance of activities that cause pain. Occasionally, injections of corticosteroids are performed and, rarely, surgical therapy is attempted all with the goal of reducing the clients’ pain to enable them to return to the activities and sports they love.”
Benefits of rESWT
- Fast, safe and effective
- Decreases pain and increases function
- No incision; no risk for infection at the treatment site; no scarring
- Future treatment options are not limited
- Does not require anesthesia
- Both sides can be treated at the same time, if the condition requires
- Clientss can continue their current level of activities
Common Conditions Treated
What Can You Expect?
To begin, a Collegiate Sports Medicine Practitioner will determine if you are an eligible candidate for rESWT treatment & that it is the best treatment option for you. This includes a complete investigation and documentation of medical history, symptoms, previous injuries and also takes your lifestyle into consideration. The practitioner will then perform a hands-on evaluation of the area including observing structure, alignment, strength, range of motion, soft-tissue damage as well as identifying any abnormalities. With this thorough assessment, the practitioner will determine your specific needs. If it appears you will respond favorably to rESWT, a treatment plan will be discussed as well as any other questions you may have.
Each treatment session lasts approximately 5-15 minutes where the practitioner or assistant will apply ultrasonic transmission gel to the target area. The rESWT handpiece is then positioned to gently and extensively transmit shockwaves into the injured area. The feedback you provide helps your practitioner fine-tune the position of the applicator & the intensity of the treatment. An initial assessment & shockwave treatment can be booked for the same time if time permits in the schedule. Current clients who have already had an orthopaedic assessment completed can discuss with their practitioner if Shockwave Therapy is an option.
Although previous generations of rESWT machines could cause considerable pain requiring freezing or local anesthetic, the radial shockwave technology Collegiate Sports Medicine utilizes does not generally cause this level of discomfort. Although it can be intense, many clients describe their treatment as “strange” or mildly uncomfortable” but few report any significant or lasting pain.
After treatment, clients may experience temporary soreness, tenderness or swelling for a few days following the procedure. Upon completion of your treatment you often can return to most regular activities almost immediately.
Number of Treatments
Clients typically require 3 separate treatment sessions other conditions may be treated with 1-8 treatments. These treatments will be scheduled accordingly & be approximately 5-14 days apart.
When Should I Consider rESWT?
- When there are no significant or serious side effects or contraindications.
- When you have been diagnosed with a condition that rESWT has been demonstrated effective in treating.
- When other conservative treatments have failed or did not work.
- When you understand the procedure, costs and other factors involved in your treatment program.
As is the case with most medical treatments, we cannot guarantee how you will respond to treatment or if you will see a significant improvement. Therefore, it is important to talk to your therapist as they can suggest other treatment options for you.
rESWT Should Not Be Used If You Have
- Diabetes Mellitus, Occlusive Vascular Disease, Collagen Disease
- Cardiac Arrhythmia or Cardiac Pacemaker
- On Immunosuppressant agents within 6 months
- Degenerative Joint Changes
- Circulation or Nerve Disorders
- Bone Tumors
- Active Infection
- Metabolic Bone Conditions
- Open Wounds
- On Anticoagulants
- Are pregnant as the effects on pregnancy have not been evaluated
- Unable to localize pain have a relative contraindication to treatment. These include patients with Alzheimer’s Disease, or other brain conditions, or patients with diffuse pain or many sites of pain making localization of the origin impossible.
- Are on blood-thinning medications or have severe circulatory disorders may also not be eligible for treatment.
Please carefully consider all factors prior to making your decision for rESWT, as there is a no refund policy in effect.
What the Research Has Said:
In a recent study with 54 knee patients, rESWT was found to be more effective and safer than traditional conservative treatments in the management of clients with patellar tendinopathy. At the three year follow up from treatment, 100% of subjects treated in this study reported fair to excellent results.(3)More and more research indicates that low energy rESWT is as effective as high energy ESWT and at a better value to the podiatric physician, insurance company, and most importantly the patient.(4)
rESWT can be strongly recommended for clients with therapy resistant plantar fasciitis. Especially in the cases of failed nonsurgical treatment, rESWT represents an excellent alternative to surgery because anesthesia is not required and long recovery times are avoided. Clients are not required to refrain from sport activities during the course of treatment and treatment can be administered outside the hospital.(5)
Radial shockwaves are generated ballistically by accelerating a bullet to hit an applicator, which transforms the kinetic energy into radially expanding shockwaves.(6,7)
A recent study published found rESWT to be safe and effective in the treatment of clients with lateral epicondilytis of the elbow. One to two years following treatment results showed 61.1% free from complaints, 29.5 % were significantly better, 6.8% were slightly better and 2.3% were unchanged.(8)
