How far do stabilometric and clinical parameters correlate in peripheral neuropathies?

Area of Science:

• Neurology
• Biomedical Engineering
• Rehabilitation Science

Background:

• Peripheral neuropathies involve damage to motor and sensory nerve fibers, impacting balance and proprioception.
• Assessing balance disorders is crucial for identifying appropriate rehabilitation interventions.

Purpose of the Study:

• To investigate the correlation between proprioception, force, and the limits of equilibrium (LOE) parameter in patients with peripheral neuropathy.
• To determine if the LOE parameter can differentiate between motor, sensory, and mixed neuropathy subtypes.

Main Methods:

• Evaluated 38 patients with peripheral neuropathy and 11 healthy subjects.
• Utilized clinical evaluation (motor and pallesthesic scores) and balance measures on a stabilometric platform.
• Calculated the limits of equilibrium (LOE) as a percentage of foot length.

Main Results:

• Stabilometric platform measures differentiated patients from healthy subjects but not patient subtypes.
• The LOE parameter successfully distinguished between patients and healthy subjects.
• LOE differentiated between motor and sensitive neuropathy forms, with a 15% threshold showing 75% sensitivity and 72% specificity via ROC analysis.

Conclusions:

• The limits of equilibrium (LOE) parameter is a valuable tool for assessing balance disorders in peripheral neuropathy.
• LOE can effectively discriminate between motor and sensory neuropathy subtypes.
• A simple experimental procedure using LOE can guide future rehabilitation strategies for these patients.
