Balance and muscle strength tests in patients with osteoporotic vertebral fractures to develop tailored rehabilitation programs

Abstract

Authors perform a cross-sectional study of functional abilities of the patients with osteoporotic vertebral fractures (VFs). Trunk muscle isometric strength and postural balance impairments were estimated. The development of osteoporotic VFs is associated with a significant decrease in strength of all the body muscles, especially the deep spinal stabilization system, i.e trunk extensor (TE), trunk flexsor (TF), where the VFs contribute to inappropriate distribution of back muscle strength with TE:TF ration of 1:1 instead of 3:2, observed both normally and in patients with uncomplicated osteoporosis. There is also a deterioration of stabilometry and functional coordination assessment tests in patients with pathological VFs, that indicate abnormalities of both static and dynamic postural balance. The obtained data should be taken into account when developing rehabilitation programmes for osteoporosis patients who have suffered compression VFs.
