A Santa Rosa chiropractor convicted of sexually assaulting a woman patient under the guise of legitimate health treatment was sentenced Tuesday to six years in prison.

Brian Icke, 54, was convicted in January of the 2011 assault on a 60-year-old woman who came to him for help after a car crash.

She testified Icke touched her vagina and breasts while the two were alone in a closed examination room, and that she bolted from the room after he made lewd comments about her body.

Icke was the subject of similar accusations in Contra Costa County about 15 years earlier. He settled the case brought by two women patients with a short jail sentence and probation.

Prosecutor Tania Partida asked Judge Rene Chouteau to consider both cases in handing down a punishment. Partida said his first conviction ended with a wrist slap.

"And in his mind he could do it again to another victim," she told the judge.

Icke's wife, who was a partner in the chiropractic business, pleaded for leniency. Icke faced up to eight years in prison. The judge settled on the mid-range sentence.

In addition to the prison time, Icke will be required to register as a sex offender for the rest of his life. He was also stripped of his chiropractic license.
