Does neuromuscular electrical stimulation (NMES) mitigate postsurgical muscle weakness in older individuals with diabetes mellitus after cardiovascular surgery?

In one paragraph

Electrical Muscle Stimulation Unit, a randomized controlled trial — the percent change in isometric knee extension strength (%ΔIKES) was significantly lower in the NMES group (mean -2%) compared to the sham group (mean -13%). The percent change in maximum walking speed (%ΔMWS) was also significantly lower in the NMES group, while percent changes in usual walking speed (%ΔUWS) and grip strength (%ΔGS) were lower but not significantly different between groups.

Plain-English summary written and published by Magellan Longevity · medical review by Gabriel Radu, DO (physiatrist, NPI 1376861765). We summarize what the paper reported — we did not run this study.

The takeaway

Neuromuscular electrical stimulation (NMES) can help reduce muscle weakness after cardiovascular surgery in older diabetic patients.

The question

Does neuromuscular electrical stimulation (NMES) mitigate postsurgical muscle weakness in older individuals with diabetes mellitus after cardiovascular surgery?

What they tested

Neuromuscular electrical stimulation (NMES) will reduce postsurgical muscle weakness in older individuals with diabetes mellitus who have undergone cardiovascular surgery.

How they did it

This was a multicenter, randomized, controlled trial. Patients aged 65 years or older with diabetes who underwent cardiovascular surgery were screened and randomly assigned to either the NMES or sham group. The primary outcome was the percent change in isometric knee extension strength (%ΔIKES) from preoperative to postoperative day 7. Secondary outcomes included percent change in usual walking speed (%ΔUWS), maximum walking speed (%ΔMWS), and grip strength (%ΔGS). Intention-to-treat analysis was performed by a blinded statistician using a student t-test.

What they found

Out of 1151 screened participants, 180 (90 in NMES, 90 in sham) were included in the primary analysis. The percent change in isometric knee extension strength (%ΔIKES) was significantly lower in the NMES group (mean -2%) compared to the sham group (mean -13%). The percent change in maximum walking speed (%ΔMWS) was also significantly lower in the NMES group, while percent changes in usual walking speed (%ΔUWS) and grip strength (%ΔGS) were lower but not significantly different between groups.

Percent Change in Isometric Knee Extension Strength (Pre- to Post-Op Day 7)
Values shown: Percent Change (%)
NMES Group-2
Sham Group-13

The NMES group experienced a -2% change in isometric knee extension strength, while the sham group experienced a -13% change.

What it means

A short course of neuromuscular electrical stimulation (NMES) for less than one week mitigated postsurgical muscle weakness and functional decline in older individuals with diabetes mellitus.

Limitations

The abstract does not explicitly state any limitations of the study.

Where the published abstract does not list limitations, we say so rather than inventing them. Read the full paper on PubMed before drawing conclusions.

Electrical Muscle Stimulation Unit

In controlled trials, NMES attenuates muscle loss and weakness during disuse (leg immobilization, ICU admission, and after knee surgery) and increases quadriceps strength, with cellular studies showing preserved muscle-fiber size and contractility.
