Welcome to another edition of ORIEMS FIT Research Digest, where we simplify fascinating research to inspire curiosity and practical learning.
Today, we explore a groundbreaking study on how Combined Neuromuscular Electrical Stimulation (Comb NMES - a niche of EMS) can improve glucose metabolism, muscle health, and metabolic function after spinal cord injury (SCI).

Whatās This Research About?
The study, titled The Effect of Lower Limb Combined Neuromuscular Electrical Stimulation on Skeletal Muscle Signaling for Glucose Utilization, Myofiber Distribution, and Metabolic Function After Spinal Cord Injury, investigates how early intervention with Comb-NMES can counteract the severe metabolic challenges faced by SCI patients.
Who Conducted This Research?
- Authors: Amal Alharbi, Jia Li, Erika Womack, Matthew Farrow, and Ceren Yarar-Fisher.
-
Institutions: Conducted at leading U.S. universities, including:
- University of Alabama at Birmingham
- Ohio State University
- Mississippi State University
- Published In: International Journal of Environmental Research and Public Health in October 2023.
These institutions are highly regarded for advancing medical and rehabilitation research, ensuring the studyās credibility.
Who Was Studied?
The study included:
- 20 SCI patients (14 days post-injury, aged 31 Ā± 9 years).
- Participants were split into two groups:
- Comb-NMES Group: Received NMES combined with resistance and aerobic exercises.
- Control Group: Received standard care with a sham intervention.
What Did the Researchers Do?
- Participants in the Comb-NMES group underwent:
- Resistance Exercise: Stimulated knee extensions using electrical pulses.
- Aerobic Exercise: Low-frequency stimulation targeting leg muscles.
- The program lasted 2ā5 weeks, with three sessions per week.
Key Findings: How Does Comb-NMES Help?
1. Improved Glucose Metabolism
- Fasting Blood Glucose: Decreased by 19.9 mg/dL in the Comb-NMES group (compared to 7.3 mg/dL in controls).
- Insulin Sensitivity: Enhanced by promoting the uptake of glucose in muscle cells.
2. Healthier Muscle Composition
- Type I Muscle Fibers (Fatigue-Resistant): Increased by 9%.
- Type IIx Fibers (Fatigable): Decreased by 36%.
3. Better Lipid Profiles
- LDL Cholesterol: Reduced by 20.5 mg/dL in the Comb-NMES group, while it increased in the control group.
Why Is This Important?
SCI often leads to muscle atrophy, metabolic issues, and increased risk of diabetes. Early intervention with Comb-NMES:
- Helps restore muscle health and insulin sensitivity.
- Improves overall metabolic function, potentially reducing long-term complications.
How Does This Help EMS Users?
For EMS users, this study highlights:
- The importance of combining electrical stimulation with resistance and aerobic exercises.
- Practical benefits for improving muscle composition and glucose metabolism.
