Focused shockwave therapy (FSWT) – modern treatment for chronic pain and tissue regeneration

How does focused shockwave therapy work?

Shockwaves are generated outside the body and transmitted through a contact applicator. Acoustic impulses with very high energy (up to 0.6 mJ/mm²) are precisely directed to the treatment area. This leads to:

• mechanical stimulation of tissue – microdamage triggers a cascade of regenerative responses,
• release of growth factors (VEGF, eNOS, BMP-2) – stimulation of angiogenesis and vascular repair,
• increased cellular metabolism – improved oxygenation and nutrient supply to cells,
• reduced muscle and fascial tension – a neuromodulatory effect,
• breakdown of calcifications and fibrin deposits – especially at tendon attachments.

Applications of focused shockwave therapy – broad indications

Focused shockwave therapy is used in orthopedics, rehabilitation, sports medicine, rheumatology, and pain medicine. Its effectiveness has been confirmed in numerous randomized clinical trials and meta-analyses.

Most common indications for therapy:

Enthesopathies (changes at tendon and ligament attachments):

• heel spur, plantar fasciitis (plantar fasciitis),
• tennis and golfer’s elbow (lateral and medial epicondylopathy),
• Achilles tendinopathy,
• subacromial bursitis and rotator cuff injuries,
• supraspinatus tendinopathy.

Myofascial pain syndrome (MPS):

• trigger points in the neck, back, and limbs.

Chronic spinal pain – related to overload, degeneration, and paraspinal muscle tension.
Pseudoarthrosis and delayed bone union – stimulation of osteogenesis.
Periarticular calcifications and tendon calcifications.
Iliotibial band syndrome, compartment tightness syndromes.

How quickly does focused shockwave therapy work?

Therapeutic effects can be divided into:

• immediate (after 1–2 sessions): pain reduction, improved range of motion, muscle relaxation,
• medium-term (after 3–5 sessions): repair of microdamage, improved tissue structure,
• long-term (after several weeks): lasting collagen remodeling, angiogenesis, increased strength and musculoskeletal function.

Optimal results are usually achieved in a series of 3–6 sessions spaced 5–7 days apart.

Who is focused shockwave therapy for?

Focused shockwave therapy is intended for patients:

• with chronic pain resistant to other treatments,
• professional and recreational athletes (overuse injuries),
• after orthopedic and reconstructive procedures,
• with limited mobility due to tissue degeneration,
• in rehabilitation – as a supportive method that speeds healing.

When can shockwave therapy be started?

Physiotherapy using focused shockwave therapy may be introduced:

• within days after injury or surgery – when there are no contraindications, as a method stimulating regeneration (subtherapeutic mode),
• after the acute inflammatory phase has resolved – to maximize analgesic and reparative effects,
• at any stage of chronic disease – including degenerative tendinopathies and overload conditions.

The decision to begin therapy should be made by a physiotherapist or physician after thorough clinical examination.

Tissue regeneration with focused shockwave therapy

Therapy acts deeply at the cellular level:

• activates progenitor cells and fibroblasts,
• stimulates production of new type I and III collagen,
• improves microcirculation and angiogenesis in underperfused tissue,
• accelerates cellular metabolism and tissue detoxification,
• reduces oxidative stress and chronic inflammatory tension.

Thanks to these properties, focused shockwave accelerates regeneration of tendons, ligaments, muscles, and articular cartilage.

The role of focused shockwave in rehabilitation – synergy with physiotherapy

Focused shockwave therapy is an excellent complement to comprehensive rehabilitation, especially:

• when therapy is resistant to conventional methods,
• to accelerate healing of microtrauma and overload,
• before active exercise (pain reduction),
• as part of manual therapy and physical therapy.

Its use can shorten treatment time by as much as 30–40% compared with exercise or manual therapy alone.

Contraindications to focused shockwave therapy

Although FSWT is safe and non-invasive, there are contraindications:

• pregnancy,
• active malignancy in the treatment area,
• fresh thrombosis, bleeding disorders (hemophilia, anticoagulant medication),
• active infections, skin and soft tissue inflammation at the treatment site,
• implanted pacemaker (caution in the chest area),
• advanced osteoporosis,
• children and adolescents during rapid growth.
