“…Previous studies showed lace-up braces prevent IV sprains, provide proprioceptive feedback, give compression to the ankle, and are not rigid like the hinged braces therefore making them more comfortable, but do restrict some motion in the sagittal plane. [17]…”

Introduction: Ankle braces can effectively decrease the incidence of recurrent ankle sprain; however, whether the brace can decrease the severity of sprain and its related mechanism during sprain remain unknown. Methods: Twenty-two patients with functional ankle instability (FAI) (12 males and 10 females) and 16 healthy subjects (8 males and 8 females) were enrolled in this study. All of the subjects walked on a custom-built tilting platform that offered a 30° inversion (IV) to mimic the IV of ankle sprain. We collected the kinematic and surface electromyography data of patients with FAI with or without ankle brace and normal controls 6 times. Results: The FAI without brace group showed significantly higher maximum IV angles and average IV velocities than the control group (P < .001). The FAI with brace group revealed significantly lower maximum IV angles and average IV velocities than the FAI without brace group (P < .001); this group also showed significantly higher maximum external rotation (ER) angle and average ER velocities than the FAI with brace (P < .001) and control (P < .001) groups. The FAI with brace group indicated significantly lower average EMGPrep (P = .047), EMGTilt (P = .037), and EMGafterTilt (P = .004) of the peroneus longus than the FAI without brace group. Conclusions: The ankle brace could effectively decrease IV angles and their velocities and increase ER angles and their corresponding velocities during ankle sprain in patients with FAI. It could also decrease the activity of the peroneus longus muscle during ankle sprain.

“…Furthermore, there is a consensus that ankle orthotics reduces the vertical jump height [ 6 – 12 ]. Also, the features of ankle orthoses should be considered as they affect jumping performance [ 8 ]. Ankle orthoses are biomechanically designed using a wide variety of materials to control, limit, and immobilize the motion for ankle joint.…”

“…Ankle orthoses are biomechanically designed using a wide variety of materials to control, limit, and immobilize the motion for ankle joint. This effect of jump performance may be due to a decrease in the ankle range of motion (ROM) in the sagittal plane [ 10 , 11 ], rectus femoris and calf muscle activity [ 8 , 9 , 11 ], or vertical ground reaction force (VGRF) [ 8 , 12 ].…”

“…However, since the ankle orthosis-related decrease in jump height is small (0.013 m) [ 10 ], it is controversial whether ankle orthotics influences vertical jump performance during practice or competition. Most previous studies focused on the maximum jump height for static vertical jumps such as squat jump (SJ) [ 8 – 10 ] or countermovement jump (CMJ) [ 6 – 8 , 11 ] not for repetitive rebound jump. Reactive strength may be used to assess the athlete’s ability to attain maximum jump height and minimum ground contact time during repetitive rebound jump (RJ) [ 13 ].…”

Background Ankle orthotics decreases the maximal vertical jump height. It is essential to maximize jump height and minimize ground contact time during athletic performance. However, the effect of ankle orthotics on athletic performance has not been reported. We aimed to investigate the effect of ankle orthotics on squat jump (SJ), countermovement jump (CMJ), and repetitive rebound jump (RJ) performance. Methods Twenty healthy volunteers performed SJ, CMJ, repetitive RJ under no-orthosis and two orthotic conditions (orthosis 1 and orthosis 2). During SJ and CMJ, we measured the vertical ground reaction force and calculated the following parameters: jump height, peak vertical ground reaction force, rate of force development, net vertical impulse, and peak power. During repetitive RJ, the jump height, contact time, and RJ index were measured. A two-dimensional motion analysis was used to quantify the ankle range of motion in the sagittal plane during SJ, CMJ, and repetitive RJ. Results Multivariate analysis of variance and the post hoc test showed orthosis 2 significantly decreased in the vertical jump height (p = 0.003), peak power (p = 0.007), and maximum plantarflexion and dorsiflexion angles (p < 0.001) during SJ Ankle orthoses 1 and 2 did not influence to the RJ performance compared to those using the no-orthosis condition. Additionally, orthosis 2 significantly decreased the jump height at the end of repetitive RJ (p = 0.046). Conclusions These results suggest that ankle orthosis do not affect average RJ performance but should be considered when performing repetitive jumps frequently.
