Effect of Different Landing Heights and Loads on Ankle Inversion Proprioception during Landing in Individuals with and without Chronic Ankle Instability

Abstract

Proprioception is essential for neuromuscular control in relation to sport injury and performance. The effect of landing heights and loads on ankle inversion proprioceptive performance in individuals with or without chronic ankle instability (CAI) may be important but are still unclear. Forty-three participants (21 CAI and 22 non-CAI) volunteered for this study. The Ankle Inversion Discrimination Apparatus for Landing (AIDAL), with one foot landing on a horizontal surface and the test foot landing on an angled surface (10°, 12°, 14°, 16°), was utilized to assess ankle proprioception during landing. All participants performed the task from a landing height of 10 cm and 20 cm with 100% and 110% body weight loading. The four testing conditions were randomized. A repeated measures ANOVA was used for data analysis. The result showed that individuals with CAI performed significantly worse across the four testing conditions (p = 0.018). In addition, an increased landing height (p = 0.010), not loading (p > 0.05), significantly impaired ankle inversion discrimination sensitivity. In conclusion, compared to non-CAI, individuals with CAI showed significantly worse ankle inversion proprioceptive performance during landing. An increased landing height, not loading, resulted in decreased ankle proprioceptive sensitivity. These findings suggest that landing from a higher platform may increase the uncertainty of judging ankle positions in space, which may increase the risk of ankle injury.

Assessment of the Efficiency of Measuring Foot and Ankle Edema with a 3D Portable Scanner

“…Also, in the field of sports, the analysis of the foot morphotypes of the athletes using this device could make it possible to improve the performance of the shoes while avoiding the most common injuries. Some of them are due to an inappropriate distribution of the volume of the shoes or a bad adaptation to the foot variations during exercise [49][50][51].…”

Cutting-Edge Research in Sports Biomechanics: From Basic Science to Applied Technology

“…The integration of sports biomechanics and bionics has the potential to transform sports and athletics by optimizing performance, reducing the risk of injury, and providing personalized training recommendations. For example, biomechanical analyses can help identify and correct flawed movement patterns that may lead to injury [ 12 , 13 , 25 ]. Bionic technologies can also provide support and protection to the musculoskeletal system, reducing the risk of injury during training and competition.…”

“…Wearable sensors, motion capture systems, force plates, 3D printing, and virtual reality are just a few examples of applied technologies used in sports biomechanics. These tools provide precise measurements and data that are used to analyze and optimize human movement [6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Furthermore, they enable the development of custom-fit equipment, training programs, and injury prevention strategies that are tailored to athletes' individual needs.…”
