The ‘hand-brain-emotion’ axis: a theoretical model for handicraft art-based intervention in anxiety disorders through neuroplasticity and autonomic regulation

This review proposes a theoretical model, the hand-brain-emotion axis, which is based on the neuro psychological theory of how handicraft art activate specific brain regions to enhance neuroplasticity and emotional regulation. Anxiety disorders are common mental health disorders that have a profoundly impact on patients' quality of life. Current pharmacological treatments, while effective to some extent, are limited in efficacy and often accompanied by side effects. Against this backdrop, exploring non-pharmacological interventions has become crucial. Research has demonstrated that handicraft art activities can substantially attenuates anxiety levels and promote the secretion of neurotransmitters, thereby improving mental health. This review aims to provide a theoretical foundation for future clinical designs of diverse handicraft art programs to improve the emotional and cognitive functions of anxiety disorder patients. It also offers theoretical support for further exploring the dynamic effects of handicraft art activities on the brain using techniques such as neuroimaging and neuroelectrophysiology. The hand-brain-emotion axis theory presented in this review provides a solid theoretical basis for the application of handicraft art activities as a novel therapeutic approach for anxiety disorders. It is also expected to promote innovation and development in the fields of neuropsychological health and art therapy.
