Breaking Barriers in Rehabilitation: A Revolutionary Japanese Study on FES and EMS

Welcome to ORIEMS FIT Research Digest!
In each post, we explore fascinating new research that sparks curiosity and inspires discovery. Today, we’ll uncover a groundbreaking study from the prestigious Nara Medical University in Japan that sheds light on Functional Electrical Stimulation (FES) and its relationship with Electrical Muscle Stimulation (EMS).

By the end of this blog, you’ll understand how these two techniques connect, how they differ, and why this matters for anyone using EMS for recovery and rehabilitation.

The Study at a Glance

Title: Contralaterally-Controlled Functional Electrical Stimulation-Induced Muscle Contraction for Severe Lower Extremity Paralysis
Authors: Tadashi Imura, Hiroki Wada, Motoya Matsui, Naoki Hotta, Tomoo Mano
Published In: The Journal of Physical Therapy Science, 2023

This innovative study explores how FES can restore lost movement in individuals with severe motor paralysis. Conducted at Nara Medical University, a leading institution in Japan known for its advancements in rehabilitation sciences, the research reveals a unique method for muscle recovery that combines cutting-edge technology with clinical expertise.

Who Conducted and Funded the Study?

The research was performed by experts from Nara Medical University and the Nara Prefecture General Medical Center, institutions celebrated for their pioneering work in rehabilitation. Located in Nara, Japan, these centers are equipped with advanced facilities and supported by leading medical professionals.

While the device used in the study was created by OG Giken Co., Ltd., the research itself was independently conducted without financial influence, ensuring reliable and unbiased results.

What Is This Study About?

This research focused on using Functional Electrical Stimulation (FES) to help a patient with severe paralysis regain movement in his lower limbs. The method involved stimulating the paralyzed side by monitoring the healthy side—a groundbreaking approach that bridges the gap for those with no initial muscle activity.

What Are FES and EMS?

While FES and EMS both rely on electrical currents to activate muscles, they serve distinct purposes:

What They Have in Common

1. Electrical Stimulation: Both methods use electrical signals to stimulate muscle contractions.
2. Rehabilitation Focus: Both are used to improve muscle function and aid in recovery.
3. Non-Invasive: They are applied externally, making them safe and accessible.

What Makes Them Different?

1. Purpose:

   • EMS: Primarily targets muscle strengthening, endurance, and blood circulation. It’s popular in fitness and general recovery.
   • FES: Specifically aims to restore lost movement by mimicking natural nerve signals. It’s used in cases of paralysis or severe motor impairments.

2. Application:

   • EMS: Stimulates muscles directly.
   • FES: Stimulates paralyzed muscles by monitoring signals from healthy muscles or mimicking nerve activity.

3. Complexity:

   • FES requires more precise equipment and specialized techniques, as seen in this study where the device monitored the patient’s healthy side to stimulate the paralyzed side.

Key Findings of the Study

• Improved Movement: The patient regained significant mobility in his lower limbs within two months, with results lasting over a year.
• Enhanced Strength: Muscle contractions and movement improved to the point where the patient could walk with minimal assistance.
• Safety: No adverse effects were observed, making this method a promising addition to rehabilitation programs.

How This Research Impacts EMS Users

This study highlights the potential of combining FES and EMS for comprehensive recovery:

1. Overcoming Paralysis: FES can jumpstart muscle activity in paralyzed areas.
2. Building Strength: EMS can follow FES to enhance muscle strength and endurance.
3. Personalized Recovery: Together, these methods offer a pathway for tailored rehabilitation based on individual needs.

Why Trust This Research?
