Nerve Decompression and Restless Legs Syndrome: A Retrospective Analysis

Area of Science:

• Neurology
• Surgical Innovation
• Sleep Medicine

Background:

• Restless legs syndrome (RLS) is a common sleep disorder impacting quality of life and often co-occurs with peripheral neuropathy.
• Current RLS treatments focus on symptom management, with underlying causes often unaddressed.
• Secondary RLS is frequently linked to peripheral neuropathy, for which nerve decompression surgery is a known treatment.

Purpose of the Study:

• To retrospectively analyze the impact of common and superficial fibular nerve decompression surgery on RLS symptoms.
• To quantify changes in RLS-associated symptoms using Visual Analog Scales (VAS).

Main Methods:

• Forty-two patients undergoing fibular nerve decompression surgery completed VAS scales (0-10) for various symptoms.
• Symptom severity was assessed before surgery and again at 15 weeks post-surgery.
• Data analyzed to determine changes in VAS scores and their correlation with pre-surgery symptom severity.

Main Results:

• Significant improvements were reported across most VAS categories post-surgery, excluding 'pulling' symptoms (P=0.14).
• A negative correlation was observed between pre-surgery VAS scores and symptom reduction, indicating greater improvement in patients with initially severe symptoms (r=-0.58, P<0.001).
• This suggests that the degree of symptom improvement was proportional to the initial symptom burden.

Conclusions:

• This study provides initial evidence that surgical decompression of the common and superficial fibular nerves may alleviate RLS symptoms.
• The findings suggest a potential therapeutic benefit of nerve decompression for specific RLS phenotypes.
• Further research using RLS-specific metrics and sleep quality assessments is recommended to validate these results.
