The support base 1 is provided with a fourth electrode body 16 connected to the light emitting section 10. With the included angle α reduced, the third electrode body 15 can be in abutting contact to the fourth electrode body 16. When the user performs plantarflexion, the included angle α can be decreased, so that the third electrode body 15 can be in abutting contact with the fourth electrode body 16, and at this time, the timer 13, the counter 14, the light emitting part 10 and the power supply 8 are communicated with each other, so that whether the number of times, duration and inclination degree of the sole of the foot of the user meet the requirements can be judged or recorded. The third electrode body 15 and the fourth electrode body 16 may also be metal patches. Preferably, as shown in fig. 3 and 4, the shape of the fourth electrode body 16 can be defined by a U-shape. When the elastic body 6e is in a natural extension state, the included angle α may be, for example, 80 °, so that the inclination angle of the sole can satisfy the requirement at this time.

First, the circuit is set to an open state by the main switch. Subsequently, the sole of the foot is placed on the foot rest 3a, and the sole of the foot is lightly applied with force so that the included angle α is approximately equal to 90 °, at which time the first electrode body 11 and the second electrode body 12 are separated from each other, and the third electrode body 15 and the fourth electrode body 16 are also separated from each other. Then, after the inflatable belt body 5 is bound to the thigh or the calf, the entire leg is placed on the support base 1. Then, the master switch is turned off, and dorsiflexion and plantarflexion are performed in sequence, whether the inclination angle of the sole meets the requirement can be judged by observing whether the light-emitting section 10 emits light, the duration of a single dorsiflexion movement or a single plantarflexion movement can be determined by a timer, and the total number of dorsiflexion and plantarflexion movements can be recorded by a counter.
