“…Whole-body vibration training (WBV) is a form of neuromuscular training that is being increasingly used as a preventive and rehabilitative tool [4,26,34]. WBV training has been reported to increase physiological responses of reflex and muscle activity [32,39] and muscle strength [11].…”

The aim of this study was to evaluate the effects of a 6-week WBV training program, performed on a soft, unstable surface, on peak torque, reaction time and the electrical activity of ankle muscles in recreational athletes with chronic ankle instability (CAI). 50 recreational athletes with self-reported unilateral CAI were randomly assigned to a vibration group (VIB), non-vibration group (N-VIB) or control group. The VIB and N-VIB groups performed unilateral balance training on the unstable ankle on a BOSU® Balance Trainer 3 times weekly for 6 weeks. The VIB group trained on a vibration platform, and the N-VIB group trained on the floor. Muscle reaction times and electrical activity of the peroneus brevis (PB), peroneus longus (PL) and tibialis anterior (TA) muscles were assessed in response to sudden inversion, isokinetic peak torque and isokinetic strength ratios of the ankle evertor muscles. After 6 weeks of training, a significant improvement was shown in reaction times of the PB (Pre=60.99±9.17 ms, Post1=54.90±6.99 ms, p=0.003), PL (Pre=61.20±10.72 ms, Post1=55.21±9.04 ms, p=0.007) and TA (Pre=65.31±11.78 ms, Post1=59.07±9.99 ms, p=0.007) muscles in the VIB group, whereas no significant changes were found in the N-VIB group or the control group. There were no significant changes in electrical activity, peak torque and eccentric-concentric ratio for any of the groups after training. In conclusion, a 6-week WBV training program on a soft, unstable surface improves the reaction times of the PB, PL and TA muscles in recreational athletes with CAI.

“…A further limitation might have been that no additional plantar-flexion movement of the foot of about 158 during ankle tilting was induced on the tilting platform, as demonstrated in literature. [38][39] For comprehensive results, all degrees of freedom of the ankle were tested passively as well. However, sport-related movements such as running, jumping, or cutting maneuvers (during which most ankle injuries occur), and the stabilizing effects of braces during ankle sprain mechanisms deserve further biomechanical investigation.…”

Context: Various designs of braces including hinged and nonhinged models are used to provide external support of the ankle. Hinged ankle braces supposedly allow almost free dorsiflexion and plantar flexion of the foot in the sagittal plane. It is unclear, however, whether this additional degree of freedom affects the stabilizing effect of the brace in the other planes of motion.Objective: To investigate the dynamic and passive stabilizing effects of 3 ankle braces, 2 hinged models that provide free plantar flexion-dorsiflexion in the sagittal plane and 1 ankle brace without a hinge.Design: Crossover study. Setting: University Movement Analysis Laboratory.Patients or Other Participants: Seventeen healthy volunteers (5 women, 12 men; age ¼ 25.4 6 4.8 years; height ¼ 180.3 6 6.5 cm; body mass ¼ 75.5 6 10.4 kg).Intervention(s): We dynamically induced foot inversion on a tilting platform and passively induced foot movements in 6 directions via a custom-built apparatus in 3 brace conditions and a control condition (no brace).Main Outcome Measure(s): Maximum inversion was determined dynamically using an in-shoe electrogoniometer. Passively induced maximal joint angles were measured using a torque and angle sensor. We analyzed differences among the 4 ankle-brace conditions (3 braces, 1 control) for each of the dependent variables with Friedman and post hoc tests (P , .05).Results: Each ankle brace restricted dynamic foot-inversion movements on the tilting platform as compared with the control condition, whereas only the 2 hinged ankle braces differed from each other, with greater movement restriction caused by the Ankle X model. Passive foot inversion was reduced with all ankle braces. Passive plantar flexion was greater in the hinged models as compared with the nonhinged brace.Conclusions: All ankle braces showed stabilizing effects against dynamic and passive foot inversion. Differences between the hinged braces and the nonhinged brace did not appear to be clinically relevant.

“…After training there were no significant differences in reflex activity of muscles analyzed (peroneus longus, peroneus brevis and anterior tibialis)60 . Similarly, Melnyk et al61 studied the effect of 4 weeks of vibration training on the stabilizing muscles of the ankle joint. Despite using amplitude and stimulus frequency parameters similar to those of the present study, they found no significant results after treatment.…”

The aims of this study were to analyze the effects of two different training protocols-vibratory platform and multi-component training--and to determine what kind of training creates greater adaptations on bone density and isokinetic strength of the knee extensors and the stabilizer muscles of the ankle joint in post-menopausal women. Thirty-eight women (59.8 ± 6.2 years) were randomly assigned to whole-body vibration group (WBVG), multi-component training group (MTG), or a control group (CG). The experimental groups performed incremental training for 12 weeks, three sessions/week. Significant differences were found in total fat mass and total lean mass in the training groups. In addition, both WBVG and MTG showed significant increases in isokinetic strength for knee extensors at 60°·s(-1) and at 270°·s(-1). With respect to the ankle joint, a significant increase for eversion at 60°·s(-1) and inversion at 60°·s(-1) was found in both training groups, and eversion at 120°·s(-1) only in WBVG (p = 0.012). There were no significant differences between WBVG and MTG in knee and ankle strength tests. Therefore, we found significant adaptations to whole-body vibration and multi-component training in the present study. However, the improvements were similar for both groups and we cannot claim that WBVG is better than MTG, or vice versa.
