PY - 2021 T2 - Therapeutic Modalities in Rehabilitation, 6e AB - David Draper passed away unexpectedly in March 2021 during the production of this textbook. David was a contributing author for both the Therapeutic Ultrasound and Diathermy chapters since the first edition of this text. He was widely recognized as a preeminent scholar and authority in both of those areas. His contributions to the professional literature over many years were extensive and he significantly expanded the body of knowledge relative to how the clinician should use therapeutic modalities. More importantly, David was a good friend to me and he was quite simply a good human being. He will be missed both professionally and personally.
