Effects of balance training on movement control, balance and performance in females with chronic ankle instability

Abstract

Introduction: Although chronic ankle instability (CAI) is a condition characterized by numerous ankle sprains and the recurring sensation of ankle instability, which result in activity limitations and participation restrictions. Repetition based balance training protocols on type of the balance exercises may improve the deficits often associated with CAI. The objective of this study was to determine the effect of 6 weeks repetition based balance training on movement control, balance and performance in females with CAI. Methods: A total of 30 active female with CAI were selected for this study and randomly divided into control and experimental groups. Before and after the 6 weeks repetition based balance training intervention, participants were tested by completing the Mischiati test for movement control, Y balance test for balance and the Figure-8 hop and triple-crossover hop for performance. For statistical analysis, we conducted paired and sample t tests the data were analyzed using software SPSS 16 P≤0.05 was considered significant. Results: The repetition-based balance protocol group improved the movement control (P=0.004), balance (P=0.006), figure-8 hop (P=0.001) and triple-crossover hop (P=0.003) performance. Conclusion: Despite some limitations, the findings clearly support the use of repetitionbased balance training exercises to improve movement control, balance and performance in females with CAI. Thus, future researchers should consider not only larger sample sizes but also longer-duration training programs to ensure the presence of notable adaptations in sensorimotor control that can.

The relationship between static and dynamic balance in active young adults

“…While the participants maintained a single-leg stance, the free limb moved to reach the anterior, posteromedial, and posterolateral directions (maximum possible reach) in relation to the stance foot. The participant then returned to a starting position without losing their balance [10,39].…”

“…Each individual performed 4 experimental practice trials (unaccounted tests) for each direction so that they became comfortable performing the task. After 2 minutes of rest, each participant performed 3 test trials in each direction (accounted tests) [10]. The average of 3 maximal reaches was calculated and recorded.…”

“…Proper balance control constitutes the basis for the execution of complex technical movements and improvements in athletic performance [5]. In fact, measuring postural stability and static and dynamic balance is critical to determine predictors of sports performance [6], rehabilitation, injury prevention [7], as well as to assess the efficacy of balance training in the neuromuscular system, balance control, and functional performance among children, adolescents [8], and active young adults [9][10][11]. Therefore, balance control has attracted the interest of professionals from different fields.…”

La rehabilitación funcional en el manejo del esguince de tobillo: una revisión sistemática

“…Dentro de la literatura utilizada se destaca que el trabajo de rehabilitación funcional para el esguince e inestabilidad de tobillo esta principalmente fundamentado con protocolos de equilibrio, utilización de dispositivos y superficies inestables, propiocepción, fortalecimiento mediante contraresistencias y combinación de vendajes. Protocolo de equilibrio y trabajo sobre superficies y dispositivos inestables Dentro de las terapias más utilizadas por las investigaciones encontradas en esta revisión fue el trabajo de equilibrio y trabajo sobre superficies y dispositivos inestables (22,23,24,27,29,30,31,33) Autores como Donovan et al 2015 indica que el trabajo de equilibrio y los dispositivos de desestabilización producen alteraciones que pueden llegar a ser beneficiosas para mejorar la estabilidad de la articulación y la posición invertida del pie comúnmente asociada a personas con inestabilidad crónica de tobillo, durante los ejercicios funcionales y esto está sustentado con un mayor aumento de la actividad electromiografica del conjunto de músculos (22) en concordancia (27). En su intervención encontraron que un programa de entrenamiento de equilibrio realizado en superficies inestables aumentaron drásticamente la cinemática del tobillo y, además todo lo www.revistasochmedep.cl referente a la actividad electromiografica muscular en comparación con superficies estables (27).…”

“…En consonancia con lo anterior, VahediNamin et al 2017 indica que en cualquier protocolo de rehabilitación es necesario que se incorporen la extremidad en su totalidad y no sólo la articulación del tobillo (23). Asimismo, sugieren que tanto las terapias y pruebas de evaluación incluyan tareas dinámicas cada vez más complejas, para que de esta manera requiera una mayor exigencia y reclutamiento de múltiples grupos musculares, y así se produzca una coordinación entre la cadera, rodilla y tobillo (23). Por lo tanto, este autor sugiere que un programa de fortalecimiento debe centrarse en toda la extremidad inferior, y no solo en el tobillo, ya que esto puede mejorar el rendimiento en lo que respecta tareas funcionales (23, 29, 37 -41).…”
