Introduction: Nervous-muscular diseases are a heterogeneous group of hereditary diseases of a motor unit. The common and major clinical sign is muscle weakness, together with muscular atrophy and hypotonia. Spinal muscular atrophy is a neuro-degenerative disease requiring multidisciplinary treatment. This disease involves a gradual decay of muscle fibers. Muscles involved in climbing, walking, holding neck and head and swallowing are the most affected. Muscle weakness or paralysis is generally more common in the upper than in the lower limbs. It is the most common genetic cause of infant mortality and occurs in approximately one in 10,000 live births. Purpose: The purpose of the thesis is to present spinal muscular atrophy as a rare nervous muscular disease which also occurs in Slovenia, to describe problems in the functioning of patients with SMA type II and present the profession of orthotics and prosthetics and its role in the choice of gadgets. Methods: By reviewing the literature, we obtained data for the description of the disease. We used the World Wide Web to find suitable literature, namely the Google search engine through which we accessed various contributions and other journals or official sites of health and social organizations and databases, such as: Google scholar, Cobiss, MEDLINE, and PubMed. Then, we summarized the data from the articles. To present the patient and his needs, we reviewed his medical records, had a conversation with his parents, and used their own experiences. We presented the results with the help of the estimation by International Classification of Functioning, Disability and Health Reduction. Results: In 62 areas of Activity and Collaboration, the patient had problems. In more than 17 areas, the Orthotic and prosthetics helped solve problems with medical devices. Other problems were solved by parents and his companion of a physically disabled child. Discussion and conclusion: The orthotics and prosthetics can more easily and better determine the choice of medical devices to the patient with neuromuscular disease with the International Classification of Functioning, Disability and Health Reduction. The International Classification of Functioning, Disability and Health Reduction could become a fundamental tool in the hands of orthotics and prosthetics in solving the problems of such patients in future.
