Introduction. The use of whole-body vibration (WBV) has increased in the therapeutic field for patients with osteoporosis, however, there is still some controversy about its real effects. Aim. to perform a systematic review on the use of WBV for improving bone mineral density and effects of osteoporosis in postmenopausal women. Material and methods. the search was conducted by two researchers in the MEDLINE/PubMED and SciELO databases. It was included in the study clinical trials that dealt with the influence of vibration platform treatment on osteoporosis in the Portuguese and English languages published since 2006. Results. Ten selected clinical trials were found in a total of 405 articles. There are heterogeneous results owing to the divergences of the study. Six articles presented benefits of treatment with WBV in bone parameters, one article with changes in balance and muscle strength and three with no effects after treatment. Conclusion. It is concluded that the use of WBV was presented as an option in the treatment of osteoporosis, however, studies using homogeneous methodologies are needed to compare the actual benefits of using them.

Introduction. In exercise, vibrations are performed in order to produce rapid and short changes in muscle length. These changes are detected by sensory receptors, in response try to dampen the vibratory waves through a modulation of muscle stiffness. However, its effects on the morphology of muscle tissue are still not fully established, especially after long periods of immobilization. Aim. To compare the effects of the vibratory platform on the remobilization of the extensor digitorum longus (EDL) muscle of Wistar rats with free remobilization. Material and methods. 20 rats were divided into: CG (Control), IG (immobilized), IFG (immobilization and free remobilization), IPG (immobilization and remobilization with vibratory platform). The immobilization was performed on the pelvic limb for 15 days. The remobilization with vibratory platform was done for 10 minutes daily, for 2 weeks. The EDL was processed for histological analysis of cross-sections. Results. The area, larger diameter, smaller diameter and fiber density of the EDL muscle of GI presented significant alteration when opposed to CG, IFG and IPG. The density of nuclei of the EDL muscle of IG presented a significant increase when opposed to the others, and IPG also presented a significant increase when compared to CG. Conclusion. The morphology and morphometry of the EDL muscle tissue were affected, and both free and vibration platform remobilization re-established the morphological aspects of the muscle fiber, without significant differences between the methods.

Introduction. Muscle strengthening to improve joint stability is widely used in the rehabilitation process, and the use of neuromuscular electrical stimulation is a useful tool, but the use of Aussie current still has little documentation about its effectiveness. Aim. To verify if there is a dose-response effect to Aussie current, both in the strength and in the static and dynamic stability of the deep pelvic lumbar muscles. Material and methods. 39 volunteers divided into four groups, one control and three electrostimulation with intensity variation, one with intensity at the contraction threshold (GT), another with intensity maintained at 20% more (G20), and another with intensity maintained at 30% more (G30) than the intensity at the contraction threshold. The intervention lasted four weeks, with three weekly sessions lasting 15 minutes. Initially and after the intervention period, the strength and stability of the deep muscles of the pelvic lumbar region were measured in a static and dynamic manner by a biofeedback pressure unit. Results. There was a significant increase of pressure under the lordoses in the pre- and post-evaluation moments, there were no differences in the evaluation of indirect force (dynamic stability), but there was an increase in the time for GT. The effect sizes presented advantages for the electrostimulated groups in static stability. Conclusion. The doses used did not promote significant statistical differences, but the effects were positive for the electrostimulated groups, especially with respect to static stability.

Introduction. A technique used in physiotherapy, but still underinvestigated, is the use of the Russian current as an aid in the improvement of balance. Aim. To verify the influence of the Russian current applied to the rectus femoris on balance in healthy and sedentary individuals. Material and methods. A cross-sectional clinical trial was performed at the Universidade Estadual do Oeste do Paraná – Unioeste, in the city of Cascavel – PR. The sample consisted of 20 healthy female subjects aged between 18 and 25 years, equally divided into two groups where group 1 was placebo and group 2 treatment. Initially, the proprioceptive evaluation was performed by means of a functional test (the Star Excursion Balance Test (SEBT)) and stabilometry using a baropodometer. Russian current was then applied to the femoral rectum of both limbs simultaneously for 2 weeks, 5 days a week. Results. No significant differences were found analyzing the variables, but the elevated effect size points to clinical relevance of Russian Current in functional assessment. Conclusion. The use of the Russian current in the rectus femoris did not present significant alteration on balance.
