Jim Lamers

Jim Lamers was an electrotherapy and sports physiotherapy pioneer. He qualified as a physiotherapist and masseur in Victoria in 1950. The following year he established a physiotherapy practice in Essendon, Victoria, and manufactured his first electrotherapy equipment. - for practice use.

Jim's clinical experience as a physiotherapist included more than 35 years in private practice, 7 years with the Essendon and Footscray VFL (now AFL) clubs, and treating Victorian Track and Field athletes during the 1950's and 60's. Jim served as Secretary for the Victorian Massage and Physiotherapy Association for twelve years, including the time of the 1956 Melbourne Olympic Games. He was a registered Victorian physiotherapist for 60 years, until his death in 2011.

By the 1970's Jim Lamers had developed and refined his innovative electro-medical ideas. He invented and produced his first TENS therapy unit in 1971. This is a full three years ahead of TENS development in the USA.

In 1972, Jim and his daughter, Robyn, coined the acronym T.E.N.S. while Jim was writing the first of many manuscripts on the subject. The term has taken on a life of its own and is now used throughout the world to describe portable / battery operated electrical stimulation units.

Bio Electronics Pty Ltd

Jim Lamers registered the manufacturing business, Bio Electronics Pty Ltd, in 1982. During a three decade period of invention and innovation, numerous advances and improvements to the TENS and EMS units were designed and implemented by Jim and the Bio Electronics team.

The most famous of these advances were the SportsMed Clinical model, the BioStim and EziStim product ranges, and the highly reputed PainEze plus and PainEze Xtra-R.

These products are the progenitors of today's range of ActivLife TENS, ECS and EMS machines.
