Cerebral palsy is a neurological condition that impairs muscle control and coordination, often preventing children from independently maintaining an upright standing position. Thus, to address this issue, static standing frames are commonly used as therapeutic aids, providing essential support and stability. However, existing frames fail to meet the dynamic needs of therapists and require manual adjustments. This study aims to develop an advanced, adjustable standing frame that meets the specific postural needs of children with cerebral palsy and their therapists. The frame features electric linear actuators that allow precise adjustments to standing position tilt, footrest angle, and the heights of lying and sitting positions, ensuring simplicity, safety, cleanliness, and accurate motion control. The backrest inclination can be customized using a reclining jog, and the leg tilt position is adjustable through secure connections, with lockable wheels enhancing mobility. The experiment involved five children aged 8–15 years, weighing between 12.6 and 20 kg and measuring between 105.2 and 117.5 cm in height. The frame consistently achieved a 28-s transition from lying to standing. This study contributes to the development of a highly functional and innovative static standing frame, addressing existing limitations. The frame’s adjustability and user-friendliness significantly improve therapy sessions and enhance the overall therapeutic experience for both children with cerebral palsy and their therapists. The findings have significant implications for rehabilitation and posture management, promising improved outcomes for individuals with cerebral palsy.
