A therapeutic method for treating a neurological disease by evaluating and correcting an abnormal neuraxial angle that cause abnormal biomechanically induced neuraxial stress and strain. A MOPA-based laser system can provide both high pulse energies and high spectral purity. The direct dependencies are indicated in a square matrix where each component in the group of components has a corresponding row and column. Various settings affecting number of failure thresholds and the time period to detect failures can be configured.
