Fig. 5. The Western Ontario and McMaster University Osteoarthritis Index (WOMAC) score at baseline and at 1-, 3-, and 6-month follow-ups after extracorporeal shock wave therapy in both groups. This figure shows significant improvement in the WOMAC score in both groups, for entire period (*p<0.05 for time effect, *p<0.05 for group-time interaction). Group A, 0.12 mJ/mm2 energy group; group B, 0.32 mJ/mm2 energy group.
