Background Parkinson’s disease (PD) is characterized by a range of motor symptoms as well documented sensory dysfunction. This dysfunction can present itself either “pure” disturbance or consequence sensory-motor integration within the central nervous system. study aims to investigate changes in functional connectivity primary somatosensory cortex (S1) and its clinical significance (PD), an area that has received limited attention previous neuroimaging studies. Methods included thirty-three patients with PD thirty-four healthy controls (HCs). Clinical evaluations were conducted assess manifestations, severity, capacity all patients. Resting-state MRI (fMRI) was employed evaluate six paired S1 subregions participants. Seed-based correlation (SBC) analysis utilized construct matrix among generate maps between remaining brain voxels. Finally, partial least-squares (PLS) association modified characteristics Results In matrix, demonstrated notable decrease across various comparison HCs ( p < 0.001, corrected using network-based methods). maps, hypo-connectivity primarily observed sensorimotor network common patterns for false discovery rate) default mode (DMN) distinct patterns.

Neurodegenerative disorders are characterized by the degeneration of nerve cells, causing debilitating symptoms that negatively impact patient’s quality life. Traditionally, assessment neurodegenerative relies on clinical evaluations, which subjective and inconsistent. An objective evaluation is vital to provide good care patients. With emergence robotic technology, several novel robot systems have been developed improve treatment techniques for neurogenerative disorders. Wearable robots, include motion sensors, real-time monitoring upper-limb gait movements, offers a comprehensive set information detect early signs motor deterioration. Similarly, exoskeletons more prevalently proposed as an tool. These not only enhance accuracy assessments but also reduce burden healthcare professionals automating routine tasks. few sets in recent times. This chapter aims focus discussing assessment, treatment, rehabilitation patients diagnosed with Furthermore, we will elaborate existing limitations systems, thereby highlighting scope future studies.
