FREDERICTON, N.B. – Two years after New Brunswick decided to help multiple sclerosis patients pay for the so-called liberation treatment, the number of patients who have sought the funding for the unproven therapy has fallen short of expectations.

The finance department says since April 2011, 82 people who wanted the treatment that widens constricted veins in the neck have been approved for payments of $2,500 each.

After an early flurry of applications, interest has tapered off and there have been no applications in the last two months.

Doctor Jock Murray, a neurologist at Dalhousie University in Halifax, says he’s not surprised the numbers are falling off because every month there is a new study with negative results.

The university of buffalo recently reported that a study of 30 M-S patients showed no improvements and in some cases the procedure made their disease worse.
