The patch of the electric pulse physiotherapy instrument is crooked and the middle is dry. Will it affect the use of functions?

The middle of the patch of electric pulse physiotherapy instrument is bent and dry, and its conductivity is poor. You can't feel it when the pulse intensity is small, but you may feel it slightly when the pulse intensity is large. Medical device market stores sell conductive rubber patches, so you just need to buy a new pair and wear it. You can also find it online, a few dollars a pair.
