In electrochemotherapy (ECT), pain and muscular contractions were reported as the most frequent drawbacks.
To review aimed to assess the literature describing technical advances intended to reduce muscle contraction and pain associated with electroporation (EP) effects.
The objective was to present an overview of different protocols proposed in the literature that aim to reduce muscle contraction in both ECT and irreversible EP treatments.
Thirty-three published studies reporting different protocol designs and electrode geometries were selected for analysis.
Both high frequency and bipolar/biphasic pulses can be used to reduce pain and muscle contractions in patients who undergo EP treatments. Moreover, adequate electrode design can lower EP-related morbidity.
Pain reduction in EP-based treatments can be achieved by appropriately defining the protocol parameters and the electrode design.
The desired results can be achieved with high frequency and/or bipolar/biphasic pulses.
