Filter by:Based on the relative shortage of ophthalmic surgeons in China, the long micromanipulation cycle and the existing micromanipulation training methods have their own limitations, such as traditional operating in porcine eyes limited to synchronous guidance and evaluation, while surgical simulators are very different for the simulation of real tissues, and the price is expensive and easy to lose. Based on these, the development of a digital training system, that is, based on traditional micromanipulation platforms such as animal tissue, physical microscopic instruments supplemented by synchronous surgical guidance and evaluation, can combine the advantages of traditional training and simulator, so as to improve the efficiency of ophthalmic surgeon training, and also provide digital ideas for other disciplines based on traditionally surgical teaching.
For many after spinal cord injury (SCI) there is immobilization, muscle atrophy, bone loss, fracture risk during transferring (or falls), and the risk of secondary complications, and increase in attendance care and cost. It is important to develop multi dimensional rehabilitation strategies for people after SCI to enhance functional recovery towards walking, and enhance an increase in muscle and bone to potentially prepare the injured nervous system in the event of a cure. Locomotor training (Stand retraining and step re training) an activity-based rehabilitative approach generates muscle activity and provides weight bearing and joint contact kinetics, even in individuals who are unable to stand or step independently. Cross-sectional animal and human SCI studies have demonstrated that locomotor training (LT) (stand retraining and step retraining using body weight support treadmill training) has improved the capacity to stand independently and walk at faster speeds. Neuromuscular stimulation (NMS) or electrical stimulation (ES) training is a rehabilitative approach that generates muscle activity, alternating leg extension and flexion even in individuals who are unable to stand or step independently. NMS studies for individuals after SCI have shown improvements in bone density and muscle strength after cycling and resistance training. The main purpose of this study is to address whether stand retraining and NMS compared to stand retraining alone or NMS alone will increase neural and musculoskeletal gains and provide a greater functional recovery towards independent standing. This project will be completed at two sites: Kessler Foundation Research Center (the grant PI site) and Frazier Rehabilitation Institute, University of Louisville, Kentucky.
