Shock Wave Therapy for Tendinopathy: Zapping Away the Pain?
Shock Wave Therapy for Tendinopathy: Zapping Away the Pain?
A Sound Solution
Extracorporeal shock wave therapy (ESWT) is gaining attention as a treatment for chronic tendinopathy. This non-invasive procedure uses sound waves to stimulate healing in stubborn tendon injuries.

How Does It Work?
ESWT delivers high-energy acoustic waves to the affected tendon. These waves create microtrauma in the tissue, triggering the body's natural healing response. This process can stimulate new blood vessel formation, reduce inflammation, and promote collagen production. The treatment may also have pain-relieving effects by altering nerve signaling.
The Treatment Process
ESWT is typically performed in a series of 3-5 sessions, spaced about a week apart. Each session lasts 10-15 minutes. The device is placed on the skin over the painful area, and shock waves are delivered in pulses. While some discomfort may be felt, the procedure is generally well-tolerated.
Effectiveness and Evidence
Research on ESWT for tendinopathy has shown mixed but promising results. It appears most effective for certain conditions like plantar fasciitis and calcific rotator cuff tendinopathy. Studies on Achilles and patellar tendinopathy have also shown positive outcomes. However, more high-quality research is needed to fully establish its effectiveness for all types of tendinopathy.
Pros and Cons
ESWT is non-invasive, has few side effects, and doesn't require downtime. It may be an option for those who haven't responded to other treatments. However, it can be expensive and may not be covered by insurance. Some patients experience temporary pain or bruising after treatment. It's also not suitable for everyone, such as those with certain medical conditions.
FAQs
Is it painful?
Most find it tolerable, with minimal discomfort.
How soon will I see results?
Some improve quickly, others in 6-12 weeks.
Are there any side effects?
Minor bruising or soreness possible, serious side effects rare.
How many treatments are needed?
Typically 3-5 sessions, but varies by condition.
Can it replace surgery?
Possibly, but discuss options with your doctor.
A Promising Option
While not a cure-all, ESWT offers a non-invasive option for tackling stubborn tendinopathy.
