VHT was developed in 1997 by Jock
Ruddock after reading and researching into the writings of Dr Kevin
Ryan, the last person trained by Tom Bowen, who had worked in his
clinic until Bowen's death in 1982.

Dr Ryan maintained that even up
to the day before he was taken to hospital for the last time, Tom was
amending adjusting and developing his work in a direction which bared
no resemblance to the system he was using in the mid 1970's when
Bowen taught Ossie Rentsch. (Note: Virtually all practitioners of
Bowen technique are in fact practising Ossie Rentsch?s interpretation
of Tom Bowen?s work whether or nor they were taught directly by him).
Though some practitioners have described VHT as "advanced Bowen
technique", its developer, Jock Ruddock prefers it to be
regarded as a separate modality, though it does still retain the
basic unique style of the 'Bowen move' at its core.
VHT does of course work extremely
well in conjunction with the Bowen Technique in that individual VHT
moves may be used at any point during a Bowen session. Alternatively
a whole Bowen procedure may be substituted for a VHT procedure to
achieve a more comprehensive and profound effect when addressing an
area of concern. A third possibility is to perform an entire session
using VHT moves alone.
