Randomization and blinding
BLIND
A random grouping method will be adopted. The SPSS 26.0 statistical software is used to randomly generate serial numbers and groups, and blind selection cards are made and put into envelopes (with no difference in appearance). Numbers are according to the inclusion sequence of the subjects, and corresponding experimental groups are entered according to the blind selection cards. Envelope administrators will not participate in this study, and the staff who generate the allocation sequence, enroll participants, and assign participants to interventions will be different ones without communication about the allocation. When patients are treated, the operators should follow the treatment assignment.The study will be conducted in a double-blind method. Due to the particularity of the operation, the operators (participating doctors and physiotherapists) will not be blinded, but only the electrophysiological indicator collectors, scale evaluators, data recorders, statistical analysts, outcome assessors, and the included subjects are blinded. The operators are not involved in the design of the protocol; thus, they have no determination of the potential differences of each treatment method. They only need to ensure the protocols are followed accurately, so that the treatment and results will not be influenced even though they are unblinded.
