The first edition of this textbook provided a practical guide and source of references for physicians, surgeons, therapists, orthotists, engineers and other health professionals who are involved in the management of the disabled person with spasticity. The second edition follows the same format. We have updated the chapters and provided new references and described new techniques. We hope we have covered all aspects of management from physiotherapy, seating and positioning and orthoses to the use of drugs, intrathecal techniques and surgery. We have also stressed the importance of adequate measurement techniques and, indeed, Chapter 3 has been completely rewritten by Garth R. Johnson and Arnand D. Pandyan. We hope that clinicians will continue to find this book helpful and a useful source of reference in their own practise and that it will continue to provide a solid base for a greater understanding of the management of spasticity.
