Orthosis as an integral and important part of Assistive Technology (AT) play a crucial role in enhancing mobility, stability, and functional independence for individuals with physical impairments. The design and biomechanical application of these orthotic devices must align with user-centric ergonomic principles to ensure maximum efficiency, comfort, and user compliance. This paper highlights the fundamental ergonomic considerations in orthotic designs including biomechanical alignment, load distribution, energy conservation, and human factors like cosmesis, ease of donning and doffing, safety and adaptability. Emphasis is placed on how ergonomically guided orthotic interventions can prevent secondary musculoskeletal problems, reduce rehabilitation time, and contribute to long-term adherence. By addressing the interaction between the human body and orthotic devices, this paper underscores how ergonomics contributes to functional outcomes, quality of life, and long-term adherence in rehabilitation. By aligning engineering design with human factors, the application of ergonomic principles in orthotic design bridges the gap between technology and patient-centered care.
