Utility of Ultrasonography in Assessing the Effectiveness of Extracorporeal Shock Wave Therapy in Insertional Achilles Tendinopathy

Figure 1

Transverse sonograms show 4-grade scale of tendon structure (outline of Achilles tendon traced by dotted line). (a) Grade 0—normal structure (homogenous echogenicity). (b) Grade 1—light structural changes (discrete hypoechogenic areas). (c) Grade 2—moderate structural changes (some well-defined hypoechogenic areas). (d) Grade 3—severe structural changes (extended hypoechogenic areas).
