Figure 1From: Study protocol: precision of a protocol for manual intramuscular needle placement checked by passive stretching and relaxing of the target muscle in the lower extremity during BTX-A treatment in children with spastic cerebral palsy, as verified by means of electrical stimulation Flowchart for the protocol for manual intramuscular needle placement checked by PSRM. Manual intramuscular needle placement checked by PSRM will be assessed as a PSRM-positive verification when the needle moves upon PSRM. Manual intramuscular needle placement will be defined as a PSRM-negative verification when there is no movement or only a small straight movement of the needle upon PSRM.Back to article page
