The text addresses Fundamentals of Electro Physical Agents, Course BPT 105, in accordance with the curriculum prescribed by the National Commission for Allied and Healthcare Professions (NCAHP). It is organised into five units arranged in a deliberate progression from principle to application. Unit I establishes the physical and electrical foundations upon which all subsequent material depends, including the structure of matter, electron theory, conduction, Ohm's law, electronic components, the effects of electric current, and the electrical supply together with its associated hazards. Units II, III and IV apply these foundations successively to the low-frequency currents, to electrodiagnosis and the strength–duration curve, and to the superficial thermal agents. Unit V constitutes a Practical Laboratory Manual and Record Book comprising nine structured practicals. Each practical is presented in a standardised sequence, from aim, principle and apparatus through pre-laboratory verification, procedure and precautions to the systematic recording and interpretation of findings. Throughout the work, patient and operator safety is treated not as a discrete topic but as an organising principle.

For the student, each chapter commences with explicit learning objectives, and technical terminology is defined at the point of first use. "Did You Know?" boxes place concepts within their historical and practical context, while "Clinical Pearl" boxes identify the material of greatest significance to clinical practice and examination. Chapter summaries, key terms, review questions and end-of-unit self-assessment sections together constitute a coherent revision framework. The practical chapters are supplemented by common errors, viva voce questions and assessment rubrics. The appendices provide motor point reference charts, a glossary, an OSPE question bank, case-based clinical scenarios and departmental maintenance and safety logs, and QR-linked resources extend the printed text with self-assessment and enrichment material.

For the teacher, the NCAHP syllabus forms the structural framework of the book. The uniform organisation of chapters and practicals permits the material to be delivered sequentially or assigned selectively without loss of coherence, and the record format is designed to serve both as the student's laboratory record and as an instrument of internal assessment.
