Welcome back to the ORIEMS Fit Research Digest, where we share exciting findings from trusted researchers around the world. Each post aims to spark curiosity and help you explore how science might improve your health journey. Today, we’ll look at groundbreaking research about Neuromuscular Electrical Stimulation (NMES) and its potential benefits for people with Chronic Ankle Instability (CAI).

Research Details:

Original Research Title:
"Effects of Rehabilitative Exercise and Neuromuscular Electrical Stimulation on Muscle Morphology and Dynamic Balance in Individuals with Chronic Ankle Instability"

Authors:

What Was This Study About?

The study explored how NMES, combined with rehabilitative exercises, can improve muscle strength and balance in people with Chronic Ankle Instability (CAI)—a condition often caused by repeated ankle sprains. CAI leads to muscle weakness, poor balance, and a higher risk of injury.

Who Participated?

• 47 physically active individuals, all with CAI, participated.
• They were split into four groups:
  1. Control Group (no treatment)
  2. Rehabilitative Exercise Group (REG)
  3. NMES Group (NG)
  4. Combination Group (RNG)

Methods Used:

1. NMES Therapy: Electrical stimulation applied to muscles to boost strength and function.
2. Exercises: Heel raises and wobble board routines designed to strengthen and stabilize the ankle.
3. Measurements: Muscle size was measured using ultrasound, and balance was tested with a special kit.

Key Findings:

After six weeks of therapy:

1. Muscle Growth:

   • Significant increases in muscle thickness (up to 1.96 cm in some groups).
   • Improved cross-sectional area (CSA) by 20–30% in treated groups.

2. Balance Improvement:

   • Reach distance during balance tests improved by up to 25%.
   • Participants performed hopping exercises faster, with up to 33% improvement.

3. Combination Therapy Wins:

   • The group using both NMES and exercises showed the biggest gains in muscle strength and balance.

Why Does This Matter?

If you have ankle instability or weak muscles from injuries, this research shows how NMES devices might:

• Improve your ability to balance and move confidently.
• Prevent further muscle atrophy.
• Enhance your recovery journey when paired with simple exercises.

How Can This Help ORIEMS FIT Users?

Using EMS devices like those from ORIEMS FIT could help strengthen weakened muscles over time. This study highlights how combining exercises with electrical stimulation may help users feel stronger and more stable in everyday activities.
