Better Research, Better Results


Research makes all the difference, and we are doing it right.

Astym® treatment is the only therapy approach that was produced through rigorous scientific development: from theory through basic science investigation to clinical study and practice. Theories regarding mechanisms of action for Astym® treatment were developed based on the foundation of recent histologic research identifying the primarily degenerative nature of tendinopathies, and the investigations into the use of cellular mediators, growth factors and related products to assist in the healing and regeneration of tissues. Guided by these principles and proposed theories, the Astym® process research team conducted their own basic science and clinical research to develop and refine non-invasive protocols aimed at activating a regenerative process. Once the Astym® protocols and process were optimized, clinical studies and trials confirmed Astym® treatment’s effectiveness.

At its core, Astym® treatment was developed from basic science investigations to stimulate regeneration at a cellular level and eliminate or reduce problematic scar tissue that may be causing pain or movement restrictions. Astym® treatment consistently shows its effectiveness in resolving soft-tissue injury. Not only does it demonstrate great success as a first-choice treatment, it routinely demonstrates success after other treatments have failed.

In addition to the published, peer-reviewed scientific and clinical research on Astym® treatment, perhaps one of the largest case series ever conducted is contained in the independent database, the Astym Analyst. Clinicians from all across the country independently enter data to create a national bank of outcomes data on Astym® treatment, which shows the actual response rates for each diagnosis, patient type, co-morbidities, etc. Not only does this provide a good real-world evidence base for Astym® treatment, it also gives patients and health care providers valuable benchmark data, so they know how many treatments it should take to resolve a certain condition.

Astym® treatment is a unique therapy process, and that is why research is done specifically on Astym® treatment rather than on a generic category. All of the articles below relate to Astym® treatment and its specific protocols.
