Programming Parameters
Patients require tailored stimulation patterns to help control their pain. The StimRouter system
features eight programmable parameters and can store up to eight stimulation programs on the
clinician programmer, patient programmer and EPT. Timing parameters are specified in Table
5-4. Pulse parameters are specified in Table 5-5.
