Overview
Hereditary motor and sensory neuropathies (HMSNs) are a group of inherited disorders characterized by progressive muscle weakness and atrophy, often accompanied by sensory loss, primarily affecting peripheral nerves 1.Diagnosis
Clinical history and physical examination revealing characteristic motor and sensory deficits 1.
Nerve conduction studies and electromyography (EMG) to assess axonal degeneration and demyelination 1.
Genetic testing to identify specific mutations associated with HMSN subtypes 1.Management
First-line treatments: Physical therapy to maintain muscle strength and function 1.
Adjunctive treatments: Orthotic devices to support mobility and prevent contractures 1.
Pain management: Analgesics such as gabapentin or pregabalin for neuropathic pain, though specific dosing is not detailed 1.Special Populations
Pregnancy: Limited data; management focuses on supportive care and symptom monitoring 1.
Pediatrics: Early intervention with physical therapy crucial for motor development 1.
Elderly: Emphasis on fall prevention and management of complications like joint deformities 1.
Comorbidities: Tailored care addressing coexisting conditions, such as cardiovascular issues, requiring multidisciplinary approach 1.Key Recommendations
Conduct comprehensive genetic testing to identify specific HMSN subtypes for targeted management strategies (Evidence: Expert opinion 1).
Implement early and ongoing physical therapy to mitigate functional decline and maintain mobility (Evidence: Moderate 1).
Use orthotic devices as needed to support mobility and prevent deformities, particularly in ambulatory patients (Evidence: Moderate 1).References
