Branched-chain amino acids plus vitamin D supplementation promote increased muscle strength following lumbar surgery for lumbar spinal stenosis: a randomized trial.

What Was Tested

This randomized controlled trial looks at Vitamin D, K2, Magnesium and Zinc.

Adequate nutrition is essential to address the surgical stress response and mitigate loss of muscle mass, strength, and functionality in older adults with lumbar spinal stenosis (LSS).

Who Took Part

By PubMed's age tags, the people studied were older adults.

Eighty patients who received lumbar surgery for LSS.

How the Study Was Run

The design is described as randomized and single-blind.

Because people in this Vitamin D, K2, Magnesium and Zinc study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

Only one side, usually the participants, was kept unaware of whether Vitamin D, K2, Magnesium and Zinc was given.

A single-center, single-blind randomized controlled trial.

What Was Measured

PubMed files the paper under topics including Spinal Stenosis, Amino Acids, Branched-Chain, Vitamin D, Muscle Strength, Intermittent Claudication and Dietary Supplements.

Author keywords: Amino acids, Branched-chain amino acids, Lumbar spinal stenosis, Muscle mass, Nutrition, Physical therapy and Protein.
