TU: ultrasound group; TP: paraffin group; TUV: ultrasound and vacuum massage group; TPV: paraffin and vacuum massage group and vacuum. aIt differs from Pre (p<0.05); bIt differs from P0 (p<0.05). Viscoelasticity (R6), pre-intervention (Pre), immediately (0 min, P0), 10, 20, and 30 min after intervention (P10, P20, and P30). Values presented in median (first quartile-third quartile).
