ABSTRACT Low bone mineral density (BMD) and osteoporosis are health concerns among older adults and individuals with physical, neurological, and/or mobility impairments. Detrimental changes in bone density and bone architecture occurring in these individuals may be due in part to the reduction/cessation of physical activity and the accompanying reduction of mechanical strain on bone. Changes in bone architecture predispose these individuals to fragility fractures during low-trauma events. Whole-body vibration (WBV) has been examined as an intervention for maintaining or improving bone mass among people with low BMD, because it may emulate the mechanical strains observed during normal daily activities. This article provides an overview of WBV including terminology, safety considerations, and a summary of the current literature; it is intended for rehabilitation healthcare providers considering WBV as a potential therapy for individuals with osteoporosis.

    ABSTRACT: The main goal of our pilot study was to use whole body vibration in a group of randomly selected patients with various neurological disorders and to investigate its influence on the quality of patients’ locomotion. Short-time effect was analyzed comparing individual changes in gait kinematics. 17 subjects participated in the study including children and elderly patients. The gait parameters were measured before and after 10 minutes whole body vibration exposure. Amplitude of applied vertical vibrations was 2mm with frequency of 30Hz and the training was realized in standing position. Anatomical joint angles and spatiotemporal parameters obtained before and after training were analyzed and the changes indicated positive effects of whole body vibration. Considering right and left side the gait parameters were more symmetric and depending on the severity of patient’s disease these changes were more or less significant. The improvements in gait kinematics after whole body vibration convinced us that this technique can be carefully used in patients’ therapy and it may be used together with individually planed rehabilitation processes to bring more satisfying results.

    ABSTRACT: Mechanical loading is one of the determining factors for bone modulation, and is therefore frequently used to treat or prevent bone loss; however, there appears to be no data on the effects of baseline bone quantity on this response. This study aimed to verify whether baseline bone quantity affects osteoporotic trabecular bone adaptive response to mechanical stimulation. Twenty-four female Sprague-Dawley (SD) rats were ovariectomized (OVX). After 3 weeks of OVX, rats were divided into a high bone quantity and a low bone quantity group, and rats in each group were then subdivided into 4 groups that were exposed to different loading strategies. In the loading groups, tibiae were stimulated through axial loading at 2000με of strain, for 1500 cycles each of 75s, 150s, or 250s. The sham treatment groups received no loading. Changes in BV/TV for trabecular bone in the tibia were measured at the baseline (before loading), and at 3 weeks and 6 weeks after loading. BV/TVs in loading groups of the low baseline bone quantity group were significantly increased at 6 weeks, compared with those in the no-loading groups (p<0.05), while those in the high quantity groups were not increased (p>0.05). A significant negative correlation was observed between baseline BV/TV and its relative variations at 3 weeks or 6 weeks (p<0.05). These results indicate that adaptive responses of osteoporotic trabecular bone to mechanical loading depend on baseline bone quantity.

    ABSTRACT: Most cerebral palsy children have deficits in balance, co-ordination, and gait throughout childhood and adulthood. So, it is essential to seek an ideal physical therapy program to help in solving such widespread problem. The present study was conducted to compare between the effect of vibration training and suspension therapy on balance in children with hemiparetic cerebral palsy.Patients and methodsThirty children born with hemiparetic cerebral palsy from both sexes ranging in age from eight to ten years old were assigned into two groups of equal number. Study group I received vibration training in addition to a designed physical therapy program and study group II received suspension therapy in addition to the same physical therapy program given to the study group I. Stability indices were evaluated via using Biodex instrument system before and after six months of treatment.ResultsThe results revealed no significant difference when comparing the pre-treatment mean values of the two groups (study I and study II), while significant improvement was observed in all the measuring variables of the two groups when comparing their pre and post treatment mean values. Significant difference was also observed when comparing the post treatment results of the two groups in favor of the study group II.Conclusion Suspension therapy for children with hemiparetic cerebral palsy is an excellent supplement to regularly scheduled physical therapy intervention for the purpose of improving degree of stability in those patients.
