Fig. 6From: Effects of alternating heat and cold stimulation using a wearable thermo-device on subjective and objective shoulder stiffnessSubjective values (refreshed feeling, improved muscle stiffness, and improved muscle fatigue in the area of intervention) based on the 11-point numerical rating scale (0 to 10, 0 = not at all, 10 = very much) after the four interventions: HC, alternating heat and cold stimulation; HEAT, heat stimulation; COLD, cold stimulation; NO, no stimulation. *p < 0.05, **p <0.01Back to article page
