Venusian acupuncture

At least in the Unbound Universe, the Second Doctor was familiar with Venusian acupuncture by the time of his regeneration. This involved manipulating pressure points on someone else's body, and was effective on humans.

The Unbound Doctor used it on someone who'd marginally survived a plane crash in 1997 Hong Kong, manipulating his lateral nerve to attempt to heal him. He said this was somewhat equivalent to the solar plexus, when questioned by Colonel Ross Brimmicombe-Wood, though he did not wish to elaborate.

In the Doctor's universe

In another universe, the Doctor's equivalent incarnation — commonly known as the Third Doctor — favoured Venusian aikido, a combat style which made use of similar principles; instead of healing others, he would use his knowledge of pressure points to quickly induce unconsciousness, thus allowing him to get living obstacles out of the way.
