Acetyl-L-carnitine improves pain, nerve regeneration, and vibratory perception in patients with chronic diabetic neuropathy: an analysis of two randomized placebo-controlled trials

What Was Tested

This randomized controlled trial paper looks at L-Carnitine in the context of chronic pain: fibromyalgia & crps.

How the Study Was Run

In design terms this was a randomized, double-blind and placebo-controlled study.

Random assignment meant chance, not the researchers, decided who got L-Carnitine and who got the comparison, which limits bias.

Neither the participants nor the staff measuring them knew who was on L-Carnitine, so expectations could not easily colour the readings.

The comparison arm used a placebo, so changes seen with L-Carnitine could be set against what happens without it.

The two studies were evaluated separately and combined.

What Was Measured

Topics PubMed links to this paper include Acetylcarnitine, Diabetic Neuropathies, Nerve Regeneration, Nootropic Agents, Pain, Perception and Sensory Thresholds.
