Eliminated uncomfortable paresthesias

Could salvage otherwise failing therapy

Could salvage some patients who lost tonic efficacy

Putting It All TogetherPutting It All Together

Evidence to support all the waveforms

All have comparable workability / interchangeability

HF10 has the best evidence (N, A, LB, L)

HF10 has the biggest IPG, most expensive, no tonic

HF10 no paresthesia mapping, needs monitoring

BURST engages the medial pain pathway

Boston has option to mimic all 4 waveforms

Consider IPG-free for certain patients

PNS can be a good option

Pain in a distinct nerve distribution

When SCS not feasible

No spinal access

Multiple previous spinal infections

When no IPG is desired
