Hemiparesis — Clinical Guidelines

Overview

Hemiparesis refers to weakness on one side of the body, often resulting from brain lesions affecting motor pathways. It commonly manifests as motor deficits in the limbs contralateral to the lesion 1 2 5.

Diagnosis

Clinical Assessment: Evaluation of muscle strength, coordination, and sensory function 1 5.

Neuroimaging: MRI or CT scans to identify underlying causes such as stroke or periventricular leukomalacia 1 2.

Neurophysiological Tests: Electromyography (EMG) and reflex assessments to evaluate spasticity and muscle tone 3.

Management

Physical Therapy: Modified Constraint-Induced Movement Therapy (mCIMT) is effective and safe in pediatric cases 1.

Non-Invasive Brain Stimulation: Repetitive Transcranial Magnetic Stimulation (rTMS) at 6 Hz may be combined with mCIMT, though further evidence is needed 1.

Pharmacological Interventions: Baclofen or botulinum toxin for spasticity management, though specific doses are not detailed in the abstracts 3.

Special Populations

Pediatrics: Combination of rTMS and mCIMT is safe and feasible in children with congenital hemiparesis 1.

Comorbidities: Management should consider coexisting sensory deficits and structural abnormalities, particularly in sensory network connectivity 2.

Key Recommendations

Combine mCIMT with rTMS cautiously in pediatric hemiparesis: This approach appears safe but requires further validation 1 (Evidence: Moderate).

Assess functional connectivity using fMRI in patients with sensory deficits: To better understand the relationship between sensory network connectivity and deficits 2 (Evidence: Moderate).

Evaluate spasticity with a combination of reflex and EMG parameters: Focus on specific parameters like F wave and H reflex amplitudes for moderate correlation with muscle tone 3 (Evidence: Moderate).
