Effect of physical activity and vitamin D compared with vitamin D alone on muscle strength, back flexibility and aerobic activity in patients with chronic kidney disease: A comparative study from Pakistan.

What Was Tested

This randomized controlled trial looks at Vitamin D, K2, Magnesium and Zinc in the context of muscle disease (myopathy).

To compare the differences in musculoskeletal health with vitamin D alone in comparison with vitamin D with physical activity (PA) among chronic kidney disease (CKD) patients.

Who Took Part

Patients with CKD stage 2-4 and vitamin D deficiency (<20 ng/mL) were recruited in the trial.

How the Study Was Run

The design is described as randomized and open-label.

Random assignment meant chance, not the researchers, decided who got Vitamin D, K2, Magnesium and Zinc and who got the comparison, which limits bias.

Everyone knew when Vitamin D, K2, Magnesium and Zinc was being given (open label), which is simpler to run but leaves more room for expectations to affect what is reported.

An open labeled, randomized, controlled trial was conducted at two tertiary care centers in Pakistan.

One arm received only vitamin D (VD arm), while the second arm received vitamin D along with PA (VDPA arm).

What Was Measured

The subject headings attached to it are Cholecalciferol, Exercise, Muscle Strength, Pakistan, Renal Insufficiency, Chronic, Vitamin D and Vitamin D Deficiency.
