The quality of life and functional independence of people with disabilities are significantly improved through rehabilitation and assistive technologies. The design and study of biomechanical devices for rehabilitation and assistive technologies are reviewed in detail in this work.The paper's first section focuses on the design features of biomechanical devices, outlining the value of user-centered design, ergonomic considerations, and customisation for specific user requirements. There are other design techniques investigated, including as mechanical design, sensor integration, and control systems. Emerging technologies that have the potential to improve the design and fabrication process are also mentioned, such as wearable technology and additive manufacturing.The research looks at the analysis methods employed to assess the effectiveness and performance of biomechanical devices. The use of force sensors and motion capture systems as kinetic and kinematic analysis tools is discussed. In order to improve the design and forecast how biomechanical devices would behave under various circumstances, computer modelling and simulation techniques are also being investigated. The paper also emphasises the value of user feedback and clinical trials in the iterative design of assistive and rehabilitation technology. The devices' effectiveness, usability, and user acceptance are essential components for a successful implementation.
