The effects of focused extracorporeal shockwave therapy versus deep friction massage in supraspinatus tendinopathy: A randomized controlled trial.

Researchers compared two popular hands-on treatments for supraspinatus tendinitis, a common shoulder condition in non-professional athletes. One group received focused extracorporeal shockwave therapy (essentially sound waves delivered to the injured tendon) plus exercise, while the other received deep friction massage plus the same exercise program. Both treatments helped people feel better across the board, but shockwave therapy appeared somewhat more effective at reducing pain, increasing pain tolerance in the shoulder muscles, and improving how far patients could raise their arm sideways.

The two treatments were roughly equivalent when it came to external rotation strength, rotator cuff strength specifically, and overall quality of life. The findings suggest shockwave therapy may have a modest edge for certain aspects of supraspinatus tendinitis, though the practical difference between the two approaches remained unclear.

If you are living with shoulder tendon pain and considering treatment, both of these approaches appear to help. The research shows that shockwave therapy produced somewhat larger improvements in pain relief and shoulder movement compared to deep friction massage, though both methods were combined with exercise in this study, which likely played an important role in everyone's recovery.

Neither approach produced dramatic overnight changes, so patience and consistent exercise matter regardless of which treatment path you choose. The two methods worked equally well for strength gains and overall quality of life, which suggests that individual factors like your preferences, access to treatment, and how your body responds may matter more than choosing one technique over another.

A conversation with your physiotherapist about what fits your situation and goals makes sense before deciding.

This trial offers a useful head-to-head comparison in a population we see regularly in practice. The study found that shockwave therapy produced moderately larger effects than deep friction massage on pain intensity and pressure pain threshold measures, with effect sizes that reached what we might call clinically meaningful territory.

The between-group differences were smaller or absent for external rotation, supraspinatus strength, and quality of life outcomes, which tempers any suggestion that shockwave therapy is categorically superior. The design paired both active treatments with therapeutic exercise, which makes it difficult to isolate the specific contribution of each passive modality.

This sample was relatively small (32 athletes) and focused on a specific population, so generalizability to other presentations of supraspinatus tendinopathy remains an open question. The findings may support shockwave therapy as a reasonable option for pain-dominant presentations, though clinical reasoning and patient preference should guide treatment selection.
