Functional electrical stimulation (FES) significantly improved muscle health and function in paraplegic patients over 8 months. FES training enhanced muscle size, perfusion, and strength, offering a superior alternative to ergometer training for cardiovascular fitness and preventing inactivity-related issues.

Area of Science:

  • Rehabilitation Medicine
  • Neuroscience
  • Physiology

Background:

  • Paraplegic patients experience significant muscle atrophy and reduced physiological function due to inactivity.
  • Functional electrical stimulation (FES) offers a potential therapeutic intervention to counteract these effects.

Purpose of the Study:

  • To evaluate the clinical and physiological effects of 8 months of quadriceps femoris muscle functional electrical stimulation (FES) in paraplegic patients.
  • To compare the efficacy of FES-induced standing and walking versus FES ergometer training for cardiovascular and metabolic benefits.

Main Methods:

  • 10 paraplegic patients underwent 8 months of FES training.
  • Assessments included muscle biopsies, CT scans for muscle diameter, knee extension strength, skin and muscle perfusion (telethermography, xenon clearance, thallium scintigraphy), and muscle enzyme analysis.

Main Results:

  • Significant increases observed: 86% in skin perfusion, 87% in muscle perfusion, 59% in muscle fiber diameter, and 30% in quadriceps muscle area (CT).
  • Muscle enzyme levels in spastic paraplegics normalized.
  • FES-assisted standing and walking demonstrated greater cardiovascular and metabolic benefits compared to FES ergometer training.

Conclusions:

  • FES effectively improves metabolism and induces positive trophic changes in the lower extremities of paraplegic patients.
  • FES-assisted ambulation is a more beneficial training modality than FES ergometry for improving cardiovascular fitness and preventing inactivity-related complications in paraplegics.
