简要总结
After an initial ankle sprain, Chronic Ankle Instability is one of the most common residual symptoms which include pain, swelling, recurrent sprain, episodes of ankle joint "giving away" or decreased function. Recently, Whole Body Vibration (WBV) training has been introduced as a preventive and rehabilitative tool. It can be hypothesized that WBV on unstable surfaces might enhance neuromuscular control. Therefore, the aim of this study was to investigate the effects of a 6-week WBV training on an unstable surface on body composition, balance, strength and reflex and muscle activity of ankle muscles in recreational athletes with CAI.
详细描述
Participants:
Fifty physically active recreational athletes with self-reported CAI volunteered to participate in the study. These subjects were assigned to one of three groups: the Vibration group (VIB), Non-Vibration group (N-VIB) and Control group (CON).
Each participant was informed of the risks and discomforts associated with this investigation and signed an informed consent document before the onset of the experiments. The experimental protocol was approved by the Ethics Committee of Clinical Research at the Hospital Complex in Toledo (Spain).
Procedures:
The investigators performed a randomized clinical trial with a cross over design. Participants were assessed at three time points: pre-training (Pre), post-training 1 (Post1) and post-training 2 (Post2) (6 weeks after the last training session). Measurements consisted in a body composition analysis, two balance tests, a forced ankle inversion test and an isokinetic strength test. Assessors and the researcher who performed the statistical analysis were blinded to group allocation. Measurements and the training protocol were developed in the Performance and Sport Rehabilitation Laboratory at the University of Castilla-La Mancha (Toledo, Spain).
