Paragraph starter
Research into dynamic walking principles has demonstrated the significant benefits of incorporating controlled energy storage and return (CESR) mechanisms into prosthetic foot design. Studies indicate that such designs can enhance push-off work and reduce overall energy expenditure for amputees, thereby improving gait efficiency and user comfort. This principle of energy management is crucial for developing advanced assistive technologies that better mimic natural human biomechanics.
