One proposed economic advantage of robotic devices is their capacity to mitigate the physical load and intensive staffing requirements of rehabilitation. Like the Continuous Passive Motion(CPM) machine has altered the landscape of orthopedic rehabilitation, these devices may offer similar capacities for provision of basic, physically intensive components of neurological rehabilitation. However, robotics may not ultimately increase productivity or free clinicians for more advanced therapy, as most of the current technologies require ongoing clinical oversight for patient safety.
