This book introduces an innovative, efficient, and patient’s friendly neural net constructive therapy for patients with mild to severe hemiplegia, not only in the recovery phase but also in acute and chronic phases. It explains the theory of Repetitive Facilitative Exercise (RFE), which is a combination of repetitive volitional flexion and extension movements from neurofacilitation approaches. This exercise is aimed at achieving the intended movements and lessening synergistic movement patterns by reconstructing and strengthening the neuropathways of the injured nerve tract. Instead of interpreting disorders based on reflex theory and constructing treatment methods, the new approach considers scientific treatment methods that emphasize the formation of neural pathways by improving synapse formation and transmission efficiency based on functional localization, central programs, and neural nets. Chapters provide a basic theory of RFE, offering the underlying mechanisms of nerve tract formation/strengthening, such as functional localization, voluntary movement, plasticity, and neural lateral sprouting, giving readers a comprehensive understanding of the prompt and repetitive therapy. This is followed by an exposition of practice and techniques, planning of treatment programs, and facilitation techniques for voluntary movements of the upper limb, individual fingers, and lower limb. Finally, the book introduces RFE to facilitate and enhance motor skills in walking and other functions.
