Statistical motor unit number estimation: reproducibility and sources of error in patients with amyotrophic lateral sclerosis.

abstract：INTRODUCTION:Hydroxymethylglutaryl-coenzyme A (HMG-CoA) reductase inhibitors, or statins, are widely used drugs for hyperlipidemia and are generally well-tolerated, but the can produce skeletal muscle toxicity. The molecular mechanisms driving statin myopathy are unknown. We investigated the effects of statin treatment...
