The volume provides assistance and information on the consequences of retraining and its effects on school performance as well as on the behavior and psychology of those affected.

Changing a person's innate handedness is one of the most profound interventions in the human brain. Using the non-dominant hand - especially for writing - can often lead to serious disorders and disruptions in brain function. These disruptions typically place significant psychological strain on the individual and can have lifelong consequences. In this book, the author provides an in-depth examination of handedness retraining and analyzes its potential impact on personality development through numerous case studies.

The book offers a well-founded overview of current medical and educational research. The Knot, the authoritative work on "converted handedness," is now available in a revised and updated English edition. It offers practical support for individuals affected by this issue, as well as for professionals working with children and adults who experience left-handedness or have undergone retraining.
