In an era where many passive therapy modalities are falling out of favor, one modality is bucking that trend. Extracorporeal Shock Wave Therapy (ESWT) is a relatively new modality that has rapidly growing research support for a variety of musculoskeletal conditions. A September 2018 meta-analysis of 29 RCT’s concluded:
“Extracorporeal shock wave therapy exerted a positive overall effect on pain and function for lower-limb tendinopathy.” (1)
Another recent study suggested that ESWT is not only an option for tendinopathy, but possibly the BEST option:
“Shockwave therapy significantly reduced the pain that accompanies tendinopathies and improves functionality and quality of life. It might be the first choice (for treating tendinopathies) because of its effectiveness and safety.” (2)
Check out this video demonstration of Shockwave Therapy in action, then read on to learn more about the evidence-based integration of this promising technology.
Considering our current understanding of tendinopathy, the ESWT seems to be an ideal management concept.
Unlike acute injuries that cause inflammation, tendinopathy is characterized by repeated overloading, micro-tearing, failed healing, and subsequent tendon degeneration. (3-6). The process begins with collagen fiber disruption and ends in a disorganized healing process that fails to regenerate a “normal” tendon.
For more insight about how chronic tendonitis is a misnomer for “tendinopathy”, check out this past ChiroUp blog.
Shockwave Therapy has shown promise for the management of several disorders including:
- Carpal tunnel syndrome (7,20,21)
- Lateral epicondylopathy (8,22)
- Achilles tendinopathy (10,11)
- Plantar fasciitis (12,13,14)
- Greater trochanteric pain syndrome (15)
- Medial tibial stress syndrome (16)
- ITB syndrome (17)
- Hamstring tendinopathy (18)
- Patellar tendinopathy (19)
- Rotator cuff tendinopathy (23)
Shock Wave Therapy is reportedly safe and quite simple to perform. Regarding delivery parameters, a recent systematic review concluded: “An optimum treatment protocol for ESWT appears to be three treatment sessions at 1-week intervals, with 2000 impulses per session and the highest energy flux density the patient can tolerate.” (24) A procedure lasts only a couple of minutes. Depending on state and carrier regulations, the application may generally be delegated to a trained assistant.
Shock Wave Therapy is considered investigational and is not currently reimbursed by third-party health insurance carriers. However, any associated myofascial release may be reimbursable when it is provided as a separate and distinct service from the shockwave therapy. Clinicians are forced to choose between providing Shock Wave Therapy at no additional cost vs. cash billing the patient with procedure codes 0101T or 97039 (when allowed).
Shock Wave Therapy units deliver energy in either a “focused” or “radial” fashion. Technically, only “focused” ESWT units are considered true “shockwave” modalities. Radial Pressure Wave (RPW) devices i.e. “radial” units are considered “pulse wave”. The designation may be splitting hairs since both devices share a similar treatment concept of tissue disruption for similar conditions – with differing delivery technology. Focused units have the ability for greater penetration; however, radial (pressure wave) units seem to produce similar outcomes for many musculoskeletal conditions. (25,26,28) Radial units are substantially less expensive than focused varieties.
The major Shock Wave and Radial Pulse Wave therapy manufacturers are Zimmer, Mettler, and Storz. The Chattanooga unit used in the accompanying video is manufactured by Storz. ChiroUp members are eligible for a substantial discount on Chattanooga units purchased through Scrip Hessco.
