Research

The Neubie® is a breakthrough neuromuscular electrical stimulation (NMES) device.

The Neubie device is FDA-cleared for indications such as maintaining and increasing range of motion, increasing local blood flow, and neuromuscular re-education. Since neuromuscular re-education is directly related to muscle recruitment, the Neubie is hypothesized to have a potential effect on muscle strength and hypertrophy.

The Muscular Response to the Neubie Device VS. Traditional Resistance Exercise

In this study, we compared acute changes in muscle thickness, isometric torque, and soreness before and up to 48 hours following no resistance training with the Neubie vs. traditional high load resistance training.

The Study

  • 34 Participants, Ages 18-35
  • Those that have regularly engaged in upper body resistance training for at least 6 months

Participants Underwent

  • 1 familiarization session
  • 1 resistance training session
  • 2 measurement sessions (24 and 48 hours after training)

Neubie Group

  • One arm completed no load resistance training with the Neubie
  • 4 sets of 20
    Power of 7/10 (subjective)

Traditional Resistance Training (TRAD) Group

  • One arm completed no load resistance training with the Neubie
  • 4 sets of 20
    Power of 7/10 (subjective)

Conclusion

Short-term training with the Neubie results in similar acute responses as traditional high load training in areas of increased muscle thickness, fatigue and soreness, but with lower perceived exertion. These acute effects may indicate the same amount of muscle growth or strength improvements can be achieved without the additional strain on joints, making it safe, effective, and viable alternative to traditional training.

Clinical Research

We are currently working on several formal scientific research projects, including several registered clinical trials. Here is an overview of our studies in progress, and we and are excited to share those results with you as they come available.

  • This field is for validation purposes and should be left unchanged.

Clinical Outcomes: A Multi-Center Study Looking at how NeuFit Impacts Post-Surgical Outcomes

We are working with Orthopedic One, of Columbus, Ohio, and Arrowhead Orthopedics of Southern California, to compare the outcomes for patients using the standard-of-care physical therapy protocols to recover from orthopedic surgery and patients using NeuFit.

Underlying Mechanisms: How the Neubie Impacts the Cellular Processes Related to Muscle Hypertrophy

We are working with the Muscle Physiology Laboratory at the University of South Florida (U.S.F.), led by Dr. Sam Buckner, Ph.D., to look at what happens at a biochemical and structural level as the body recovers from a NEUBIE session. One of the current hypotheses being evaluated is that the NEUBIE can be used to create muscle hypertrophy without external load.

Measuring the Autonomic Response to NeuFit Sessions

In partnership with BioStrap Labs, we are measuring the impact of the Neubie on various biomarkers, like heart rate variability (HRV), sleep quality, and blood flow. Early data is showing that the NEUBIE does increase HRV, which is a powerful indicator of parasympathetic nervous system function and has profound effects on overall health, recovery, and the ability to handle physical, psychological, and emotional stress.

Studying the Effect of NeuFit on Neurological Populations

In partnership with a couple of hospital systems, we are evaluating the ability of the Neubie to restore function in patients who have had a stroke or who have M.S. We are also working on a multi-center study to measure the impact of the Neubie on patients with neuropathy.
