A low Vitamin-D status is often reported by those with knee osteoarthritis (OA), and is often associated with increased pain and locomotor dysfunction.
The association between Vitamin-D levels and muscle function associated with balance recovery and falls is unclear.
As such this current study aimed to investigate the effect of Vitamin-D on pain, quadricep strength, lower limb mass and knee power function during balance recovery in people with knee osteoarthritis.
Results found that people with knee osteoarthritis with Vitamin-D insufficiency demonstrated poorer knee function during balance recovery, and greater pain and locomotor dysfunction.
Thus it was concluded that Vitamin-D insufficiency may have an adverse effect on muscle power function.
