Scientists from Keio University, Japan, found that the combination of a drug laced silicon implant and treadmill rehabilitation shows promise for treating spinal injuries in rats. The results suggest the combination worked better than the drug alone.
The drug released from the silicon gel was semaphorin3A inhibitor which is similar to other drugs that have previously been shown to be effective. The silicon implant proved to be a highly effective delivery mechanism. The addition of treadmill exercise improved results still further.
