Effects of low-intensity vibration and exercise on bone mechanical properties

Abstract

Bone is a dynamic, living tissue that adapts in response to forces placed upon it. Exercise exerts physical loads on bone that help maintain a healthy musculoskeletal system. Individuals with limited mobility experience bone loss faster than physically active individuals [1]. Inactivity lacks the necessary forces to continue building bone - leading to osteoporosis. Immobility may have severe effects on bone mechanical properties. Traditionally, exercise has been used as a non-pharmaceutical intervention to increase bone mass in patients with osteoporosis. However, exercise regimes can be difficult for frail, immobile, or bedridden patients. Low-Intensity Vibration (LIV) is a therapy known to promote bone health by strengthening bone and increasing its rate of formation. The bone receives vibrations that stimulate a response of new building activity [2]. To evaluate the effectiveness of LIV as an alternative to exercise, this study examines the effect of LIV in conjunction with exercise on bone properties, as well as compares the two interventions.
