Analysis of Muscular Electrical Activity and Blood Perfusion of Upper Extremity in Patients with Hemiplegic Shoulder Pain: A Pilot Study

Figure 4

Linear correlation between VAS for shoulder pain intensity and physiological measurements (sEMG parameters and blood perfusion parameters) in the affected side of HSP patients. (a) Correlation between VAS and RMS parameter of sEMG. (b) Correlation between VAS and MDF parameter of sEMG. (c) Correlation between VAS and PU value of blood perfusion.
