A single whole body vibration session influences quadriceps muscle strength, functional mobility and balance of elderly with osteopenia and/or osteoporosis? Pragmatic clinical trial

Abstract

Background The purpose of this study verify the immediate effect of whole body vibration (WBV) on quadriceps muscle strength, functional mobility and balance in elderly patients with Osteopenia and/or Osteoporosis. Methods This was a randomized pragmatic clinical trial with 34 elderly (32 women) randomly assigned to two groups: the experimental group (EG; n = 17) who underwent low-frequency (16 Hz) WBV and the control group (CG; n = 17) who performed the walk. Outcome measures were: quadriceps muscle strength measured by a maximal repetition test (1RM); functional mobility assessed by the Timed Up and Go (TUG) test and balance assessed by the Berg Balance Scale (BBS). Results In within-group interaction, a significant increase was observed in quadriceps muscle strength (EG:p = 0.047) and balance (EG: p = 0,012; CG: p = 0,007). In between-groups interaction, a significant difference was not observed. There was an increase in the muscular strength of the EG and in the balance in both groups.

Whole-Body Vibration Associated with Strength Training on the Lower-Limb Blood Flow and Mobility in Older Adults with Type 2 Diabetes: A Study Protocol for a Randomized Controlled Trial

“…The training protocol will last for 12 weeks (3 months) and comprise three times a week for 60 min each session. Before each session, the volunteers in arms G1 and G2 will be instructed by the intervention team to perform basic warming and stretching exercises accordingly to the Ramos protocol [ 21 ].…”

“…On their heels, silicon insole will be applied (semi-rigid) in order to keep only the forefoot and middle-foot in direct contact with the platform surface, thus correcting the body weight distribution and foot biomechanics changes. Both strategies will be used to minimize the axial transmission to cranial base [ 7 , 21 , 47 ]. In accordance with the International Organization for Standardization (ISO) 2631-1, all the parameters are considered safe for body exposure to mechanical vibration [ 48 ].…”

“…The whole-body vibration (WBV) training program is an alternative for a safe, effective, and low-cost exercise, which can present a satisfying compliance by previously sedentary patients [ 20 , 21 ]. It is generally assumed that vibration stimulates muscle spindles that responds with tonic vibration reflexes thereby enhancing muscle activity [ 21 , 22 , 23 ]. In the literature, two studies identified a significant blood flow increase in DM2 patients undergone vibration [ 24 , 25 ].…”

Effectiveness of Whole-Body Vibration Combined with Multicomponent Training on the Risk of Falls and Quality of Life in Elderly Women with Osteoporosis: Study Protocol for a Randomized Controlled Clinical Trial

“…Another therapeutic modality used in people with OST is whole-body vibration (WBV), a non-invasive and non-pharmacological intervention that can promote a reduction in the impact on bone mass and density, helping to gain balance and muscle strength and reducing the number and risk of falls [ 20 , 21 , 22 , 23 , 24 ]. WBV alone or in combination with exercise can also decrease the number of falls and the risk of falls, being essential to prevent bone fractures and osteoporosis [ 21 , 22 , 25 ].…”
