Abstract

Develop the understanding and clinical reasoning skills you’ll need to confidently manage dysphagia in professional practice! This logically organized, evidence-based resource reflects the latest advancements in dysphagia in an approachable, student-friendly manner to help you master the clinical evaluation and diagnostic decision-making processes. Realistic case scenarios, detailed review questions, and up-to-date coverage of current testing procedures and issues in pediatric development prepare you for the conditions you’ll face in the clinical setting and provide an unparalleled foundation for professional success.

  • Comprehensive coverage addresses the full spectrum of dysphagia to strengthen your clinical evaluation and diagnostic decision-making skills.
  • Logical, user-friendly organization incorporates chapter outlines, learning objectives, case histories, and chapter summaries to reinforce understanding and create a more efficient learning experience.
  • Clinically relevant case examples and critical thinking questions throughout the text help you prepare for the clinical setting and strengthen your decision-making skills.
  • Companion Evolve Resources website clarifies key diagnostic procedures with detailed video clips.
