Chapter 49: Neuromuscular & Muscular Disorders in Children

Neuromuscular & Muscular Disorders in Children from Maternal Child Nursing Care delves into the assessment and management of pediatric neuromuscular and muscular dysfunction, beginning with Cerebral Palsy (CP), the most common permanent physical disability in childhood. It examines CP classifications—spastic, dyskinetic, ataxic, and mixed—alongside clinical manifestations such as delayed gross motor development, abnormal muscle tone, and persistent primitive reflexes, while detailing therapeutic interventions like intrathecal baclofen pumps, botulinum toxin A injections, and orthopedic surgery to maximize mobility. The text then transitions to neural tube defects (NTDs), specifically focusing on spina bifida and myelomeningocele, emphasizing the critical role of maternal folic acid in prevention and the complex multidisciplinary care required for associated complications like hydrocephalus, Chiari II malformation, neurogenic bladder, and latex hypersensitivity. Genetic disorders are thoroughly explored, including the various types of Spinal Muscular Atrophy (SMA)—such as Type 1 (Werdnig-Hoffmann disease) and Type 3 (Kugelberg-Welander disease)—where degeneration of anterior horn cells leads to progressive weakness, necessitating respiratory support and newer gene-modifying therapies like nusinersen. Acquired neuromuscular conditions such as Guillain-Barré syndrome (GBS), an immune-mediated acute demyelinating polyneuropathy characterized by ascending flaccid paralysis, are contrasted with infectious disorders like tetanus (lockjaw) and infant botulism, the latter causing descending paralysis often linked to honey ingestion or spore inhalation. The chapter also addresses traumatic Spinal Cord Injuries (SCI), differentiating between complete and incomplete lesions and highlighting life-threatening complications like autonomic dysreflexia and neurogenic shock alongside rehabilitation goals. Furthermore, it outlines autoimmune conditions such as Juvenile Dermatomyositis (JDM), marked by proximal weakness, heliotrope rashes, and Gottron papules. Finally, the discussion concludes with the Muscular Dystrophies (MD), particularly Duchenne Muscular Dystrophy (DMD), an X-linked recessive disorder caused by dystrophin deficiency, where nursing care focuses on managing progressive muscle wasting, identifying the Gower sign, preserving respiratory function through noninvasive ventilation, and addressing cardiac complications through a palliative approach.
