It's a Scream: Chi Healing and the Art of the Super Scream

When Alan Wilensky's back was severely injured in a debilitating automobile accident, Western doctors outlook for his future was fairly grim. Given less than a 50% chance of ever walking again, Wilensky opted to turn his back on Western science and explore the ancient, self-healing Chinese art of Qi Gong. In the following years Wilensky claims to have simply used the energy generated by his body to fully recover from his devastating injuries. Now a Tai-Chi practitioner whose dedication to the martial arts has given him the strength to produce screams that appear to shatter the current world records, Wilensky uses his inner energy to conjure a scream so loud that even the most advanced audio technology cannot accurately record or reproduce it. ~ Jason Buchanan, All Movie Guide
