Liberation Therapy, Controversial MS Therapy, Caused Death Of Maralyn Clarke: Husband

THE CANADIAN PRESS -- CALGARY - A Calgary man says his wife died after getting a controversial treatment for multiple sclerosis called liberation therapy.

Frank Lamb says his wife, Maralyn Clarke, went to a California clinic to have the surgery to widen veins in her neck on April 13.

But Lamb says hours later Clarke had a massive bleed in her head called a subdural hematoma and was taken to a nearby hospital where she died on April 18.

The grieving man says his wife was diagnosed with MS about 20 years ago and felt she was going downhill, so she hoped the procedure would help relieve some of her symptoms.

The clinic where the surgery was performed, Synergy Health Concepts Inc., was not immediately available to comment.

It's the second reported death of a Canadian who had liberation therapy -- an Ontario man died in a Costa Rica clinic last October.
