(A) Two constant temperature thermal stimulators (left: cold; right: hot). (B) The therapeutic pad and the foot plate covered the entire surface of the skin below the knee, the dorsal surface of the foot, and the sole of the foot. (C) During the development of discomfort (VAS score >7), participants were encouraged to actively move their paretic LE away from the stimuli. About one third of the participants in the experimental group required 3 to 5 times of TS-induced movements of the paretic LE during 10 repetitions of TS. The most common TS-induced movement was ankle dorsiflexion 15°, knee flexion 20°, and hip flexion 20° synchronously.
