Effects of Neuromuscular Electrical Stimulation on Glucose Levels and Glucose Variability in Patients With Type 2 Diabetes: a Randomized Clinical Trial
In Brief
A clinical study evaluating NMES and NMES-placebo for Type2 Diabetes Mellitus. Completed, enrolled 28 participants across 1 site.
Detailed Summary
In patients with type 2 diabetes mellitus (T2DM) chronic hyperglycemia is the main cause of complications, promoting several micro and macrovascular damages. In order to understand other mechanisms that could have an impact on the development of these diabetic complications, the assessment of glycemic variability have been widely used. Glucose control can be achieved with multiple interventions, including exercise training. Some individuals, however, especially those with autonomic neuropathy, can have exercise intolerance. In this context, physical therapy proposes neuromuscular electrical stimulation (NMES) as a therapeutic that has been applied in research and clinical practice as an alternative to the training of patients who cannot perform conventional exercise. In patients with T2DM, NMES was shown to improve glycemic control and insulin sensitivity, but quality of these trials is poor. In addition, the effects of NMES on glycemic variability of T2DM patients have not yet been reported. The aim of this study is to evaluate the effects of NMES on glucose levels and glucose variability in patients with T2DM.

Timeline
Interventions
NMES will be placed at the knee extensors. Stimulation frequency will be 20 Hz. Pulse width will be 0.5 milliseconds and the contraction time will be 10 seconds (TON: 10s) with a 5-second rest interval (TOFF: 5s). Total time application will be 60 minutes. Intensity will be adjusted individually, taking into account the patient's ability to promote the full knee extension and comfort during contractions.
NMES-placebo will be placed at the knee extensors. Stimulation frequency will be 20 Hz. Pulse width will be 0.5 milliseconds and the contraction time will be 10 seconds (TON: 10s) with a 5-second rest interval (TOFF: 5s). Total time of application will be 60 minutes. Intensity will be adjusted with minimal intensity, utilized to provide a sensory stimulus, but insufficient to elicit a tetanic muscular contraction.
