Rehabilitation and Prosthetics

Definitional Boundaries & Taxonomy

[EN] Rehabilitation robotics and advanced prosthetics constitute a highly specialized, mission-critical sub-domain of bionics, biomechatronics, and neurorehabilitation. While conventional industrial robotics focuses predominantly on replacing human labor with deterministic, repetitive task execution, this field seeks to restore, augment, and interface directly with the biological human neuromotor system. Rehabilitation robots: such as lower-limb exoskeletons for gait re-training and end-effector based upper-limb manipulators: are fundamentally designed to deliver intensive, repetitive, and task-specific kinetic therapy. Their core objective is to induce experience-dependent neuroplasticity (Hebbian learning) in patients suffering from stroke, spinal cord injury (SCI), or traumatic brain injury (TBI). Prosthetics, conversely, focus on the functional, kinematic, and cosmetic replacement of amputated appendages via highly integrated mechatronic systems that act as an extension of the user's volition. The taxonomy of this engineering domain is rigorously divided into four pillars: 1. Active Exoskeletons (subdivided into overground ambulatory systems and tethered, treadmill-based clinical systems); 2. End-Effector Devices (where the robotic interface connects to the patient only at the distal extremities, allowing the biological joints free movement in space); 3. Bionic Prostheses (myoelectric, neuro-integrated, and Targeted Muscle Reinnervation (TMR) enabled systems); and 4. Wearable Sensory Substitution Devices (providing haptic, vibrotactile, or electrotactile feedback for the artificial restoration of proprioception and somatosensation).
