SAIBA COMO UTILIZAR O FES NA FISIOTERAPIA?

Introduction

This tutorial provides a step-by-step guide on how to effectively utilize Functional Electrical Stimulation (FES) in physiotherapy. It is designed for physiotherapists looking to enhance their practice with the application of FES, which can aid in muscle contraction and rehabilitation.

Step 1: Understanding FES Parameters

• Familiarize yourself with the key parameters of FES, including:
  • On and Off Time: Adjust the duration of stimulation and rest periods. A typical setting might be:
    • On Time: 5-10 seconds
    • Off Time: 10-20 seconds
• This timing is crucial for optimizing muscle response and preventing fatigue.

Step 2: Differentiating Between Voluntary and Electrical Muscle Contraction

• Recognize the difference between voluntary contractions and those induced by FES:
  • Voluntary Contractions: Initiated by the patient's own effort.
  • Eletroestimulação Muscular (Electrical Muscle Stimulation): Triggered by electrical impulses, useful for patients who cannot perform voluntary movements.
• This understanding helps tailor treatments according to patient capabilities.

Step 3: Exploring the Physiological Basis of Muscle Contraction

• Learn about the physiological mechanisms behind muscle contraction to inform your practice:
  • Motor Unit Activation: Understand how FES recruits motor units to create muscle contractions.
  • Neuroplasticity: Recognize how FES can facilitate neural adaptations, improving function over time.

Step 4: Setting Bioelectrical Parameters

• Adjust bioelectrical parameters for effective FES:
  • Frequency: Typically set between 30-50 Hz for muscle contraction. Higher frequencies may lead to fatigue.
  • Pulse Duration: Usually ranges from 200-400 microseconds. Experiment to find the optimal duration for each patient.

Step 5: Implementing Neuromuscular Facilitation Techniques

• Apply facilitation techniques to enhance muscle response:
  • Use of FES can aid in neuromuscular re-education by stimulating weak muscles.
  • Incorporate functional movements to encourage a more natural muscle activation pattern.

Step 6: Focusing on Muscle Strengthening

• Use FES as a tool for muscle strengthening:
  • Implement protocols that progressively increase intensity as the patient adapts.
  • Combine FES with traditional strength training for optimal results.

Step 7: Managing Muscle Amplitude and Addressing Contractures

• Monitor muscle amplitude to ensure effective stimulation:
  • Adjust settings to avoid overstimulation, which can lead to discomfort.
  • Address contractures by incorporating stretching techniques alongside FES.

Conclusion

Utilizing FES in physiotherapy involves understanding and adjusting various parameters to optimize muscle contraction and rehabilitation outcomes. By mastering the principles of FES, physiotherapists can significantly enhance their treatment approaches.
