Development of treatment

The Theraflex EPVM 1 Vertebral Mobiliser is the culmination of twenty years of research and development  


Powered mobilisation of the spine using pneumatic four cylinder mobilisers was developed and patented in 1987 by Matthew Stobart and Robert Taylor.


The first prototype units were driven by compressed air alone employing Compair miniature logic valves to control the cycling of the cylinders.

These early prototypes used the same diagonal foot extension sequence used in the EPVM1 to counter rotate adjacent vertebra, by pushing on the transverse process's of the vertebra.


Although these early prototypes produced good results they could not ramp the foot pressure between strokes, they were difficult to hold and control, were noisy and required a separate installed compressed air system to run them.


In 1997 Power Assisted Micro Manipulation Ltd, (PAMM), produced the first production version of the product, this unit featured electronic control with pressure ramping between strokes in the mobilisation mode and the ability to utilise a delay period in the firing sequence in the muscle stimulation mode.


Many PAMM handsets, (also known as TAMARS), continue to be operated successfully today, however PAMM Ltd was put in the hands of the receivers in 2001 due to the burden of development costs and management issues.


In 2002 Peter Herman, (the inventor of the Mantis range of treatment benches) and Matthew Stobart resolved to make this treatment available once again and after many years of development and certification have brought it back on the market trading as Theraflex Ltd.


The EPVM1 Vertebral Mobiliser incorporates the developments of its predecessors and includes many improvements including:


- On/Off, speed and pressure controls built into the handset itself


- A specially designed built-in silenced compressor that supplies the correct        volume of air continuously.


- The handset has a protective ergonomically designed rubber cover


- A  longer 5 metre flexible handset hose


- Improved handset silencing


- In-built compressed air de-watering unit


- No compressed air reservoir, (therefore an annual HSE  inspection is not              required)
