Figure 1 Short-term trajectory of outcome measures following a single session of extracorporeal shock wave therapy (ESWT) applied in stretching versus relaxation postures(A) Comparison of Modified Ashworth Scale (MAS) scores (median with interquartile range) for elbow flexor spasticity. (B) Comparison of normalized average electromyography (AEMG) values (mean±standard deviation, expressed as percentage of individual baseline). (C) Comparison of normalized root mean square (RMS) values (mean±standard deviation, expressed as percentage of individual baseline). (D) Comparison of Fugl-Meyer Assessment for Upper Extremity (FMA-UE) scores (mean±standard deviation). (E) Comparison of Mayo Elbow Performance Score (MEPS) (mean±standard deviation). (F) Comparison of elbow joint passive extension range of motion (PROM) in degrees (mean±standard deviation). Data were derived from standardized retrospective clinical records. Asterisks (*) indicate P<0.05 for between-group comparisons at the indicated time point (Mann-Whitney U test for MAS; independent samples t-test for other outcomes).
