ABSTRACT
OBJECTIVES:
This study aims to evaluate the association of serum vitamin D level with proximal muscle strength, tone, elasticity, and stiffness in elderly. PATIENTS ANDMETHODS:
Between September 2017 and January 2018, a total of 109 participants (21 males, 88 females; mean age 71.2±4.6 years; range, 65 to 85 years) were included in the study. The proximal muscle strength was evaluated by MicroFET® 3 device. The muscle tone, elasticity, and stiffness were measured using the MyotonPRO® digital palpation device. Serum 25-hydroxyvitamin D [25(OH)D] level was tested by high-performance liquid chromatography. A receiver operating characteristic (ROC) curve was performed to evaluate the potential role of MicroFET® 3-measured proximal muscle strength in the quantification of vitamin D status.RESULTS:
Vitamin D sufficient participants had a higher proximal muscle strength (p<0.001). Quadriceps and hamstring elasticity at the non-dominant site were significantly higher in vitamin D sufficient group (p<0.05). The ROC analysis indicated that the deltoid muscle strength had the potential of determining vitamin D insufficiency with moderate accuracy (area under the curve=0.744; 95% confidence interval 0.643-0.845; p<0.001).CONCLUSION:
Proximal muscle strength, elasticity, and physical performance are associated with vitamin D status. Proximal muscle strength measured by a hand-held dynamometer can be used as a predictor of hypovitaminosis D in elderly.
