We have not undertaken the controlled study which would be required to answer this question scientifically. Most, if not all, of iLs clients are doing the iLs program concurrent to other interventions. The cost of a double-blind, controlled study is prohibitive for a small company like iLs; nevertheless, we have ample empirical evidence of iLs’ efficacy. The combination of clinical observation and pre- and post-program measurements allow us to say with confidence that a vast majority of our clients achieve “successful” results.
