Over the past decade, robotic neurorehabilitation has become one of the most discussed innovations in neurological recovery. Robotic gait trainers, upper-limb rehabilitation systems, exoskeletons, and AI-assisted rehabilitation devices are increasingly being adopted by hospitals and rehabilitation centres worldwide. However, an important question remains: Are robots the future of neurorehabilitation—or are they simply another tool in the rehabilitation toolbox? As clinicians and researchers, we must move beyond marketing claims and focus on scientific evidence, patient selection, and clinical reasoning. What is Robotic Neurorehabilitation? Robotic neurorehabilitation involves the use of electromechanical devices that assist, guide, resist, or augment movement during therapy. These technologies include: • Robotic gait trainers • Wearable exoskeletons • Upper limb robotic rehabilitation devices • End-effector robotic systems • Sensor-based rehabilitation platforms • AI-assiste...
Polysialylation, the addition of polysialic acid chains to glycoproteins like the Neural Cell Adhesion Molecule (NCAM), plays a crucial role in brain development. Here are key points outlining the significance of polysialylation in brain development: 1. Neuronal Migration : o Polysialylation of NCAM is essential for neuronal migration during brain development. o Polysialic acid chains on NCAM reduce cell adhesion, allowing migrating neurons to detach from neighboring cells and move to their appropriate locations in the developing brain. 2. Axon Guidance : o Polysialylation of NCAM is involved in axon guidance, the process by which growing axons navigate to their target regions to establish neural circuits. o Polysialic acid on NCAM modulates axon growth cone behavior, facilitating the extension of axons and their pathfinding to specific target areas. 3. Synaptic Plasticity : o Polysialylation of NCAM contri...
