The reason for this is that the quadriceps femoris muscle is required to contract when the knee joint is straightened, and the contraction of the quadriceps muscle is time-sequential and requires coordinated contraction, and the joint moves when the muscle contracts. The above-mentioned important factors are currently ignored by electrical stimulation.
Through the above analysis, the problems and defects of the prior art are as follows: the existing electrical stimulation technology ignores the time sequence of the contraction of quadriceps femoris muscle when the knee joint is straightened, and the time sequence needs coordinated contraction, and meanwhile ignores the problem that the joint moves when the muscle contracts.
