Back extension training refers to the toes try their best to hook back, that is, the foot is hard to hook back to the limit position.
Back extension angle.
It is the angle between the extension line of the lower leg and the sole of the foot during dorsiflexion.
Plantar flexion refers to the action of the forefoot stepping down as hard as possible, that is, the foot stepping down hard to the limit position.
Ankle pump refers to the foot’s maximum return hook, which lasts for 6 seconds before stepping down to the maximum. That is, dorsiflexion and then plantar flexion, staying in both positions for 6 seconds.
Toe movement, the main point is to dorsiflex the toes as far as possible to reach the limit for 6 seconds. The toes are flexed as far as possible to the point where they can hold a pencil for 6 chimes. It means that the toes are first cocked upward to the limit and then hooked backward to the limit, staying in both positions for 6 seconds.
Heel lift means.
Toe weight, heel lift high, used to train the strength of the rear group of calf muscles. This action is also lifted to hold for 6 seconds, but do not lift too high, to not more than 5 cm is appropriate.
Static contraction exercises.
It means that the muscles of the thighs and calves contract rhythmically, a jump, you can use the healthy side of the leg to find the feeling first before doing.
Single-station exercises.
Injured leg on the ground, the healthy leg lifted, no dependence, maintain body balance; deliberately sway, lose balance, and then try to find balance. Keep repeating.
Stepping in place.
Practice the proprioception of the foot touching the ground. (Because your feet have not stepped for a long time, the feeling of touching the ground is almost forgotten, so you have to find the feeling).
Lunge, pushing the wall.
Can also play the wedge plate exercise effect, but the movement should be soft, slow, not fast downward pressure.
Push the wall at the beginning can hurt the foot in the back, practice to a certain angle, start practicing hurt the foot in front, lunge step and vice versa.
Thomsen experiment.
It is the injured person lying on the bed, feet in the hanging position, the doctor pinch your calf belly, to see if your toes have a metatarsal bending reaction.
One-step.
The good foot is in front of the injured foot in the back, the injured foot is close to the good foot, the body weight is on the good foot, the good foot stands at 90 degrees, the injured foot can still land on the whole foot, that is “can stand stable one word step”.
Angle.
Can stand is 90 degrees, can stand a word step is 100 degrees, can alternate down the stairs is 105 degrees, can squat is 110 degrees, normal people is 115 degrees.
