Evidence regarding the effectiveness of using orthotics in improving comfort, increasing running speed and helping to reduce injury rate during running is limited and mixed. Alongside the increasing popularity of running is the increasing rate of running-related injuries (RRIs). Further research into whether orthotics could be used to help reduce RRIs would be highly beneficial for those affected. Additionally, there is a need to clarify whether orthotics use increases comfort during running and helps improve running speed.
To investigate whether running with Aetrex Orthotics improves comfort and performance and reduces injury whilst running.
Runners were recruited on a voluntary basis if they were 18 or older with no serious health conditions, ongoing foot pain or deformity, previous foot surgery in their lifetime or any surgery in the past 6 mo. Participants were randomly assigned to either an intervention group or a control group. All participants were asked to complete runs and provide quantitative data regarding comfort during running, running time and distance, and any RRIs over an 8-wk study period. Participants in the intervention group ran with Aetrex L700 Speed Orthotics, whilst participants in the control group ran without orthotics. Other than the addition of orthotics for participants in the intervention group, all participants were asked to run as they usually would. This report presents preliminary data from the first 47 participants recruited for this study. Running speed was calculated from running distance and time and given in miles per hour. For each outcome variable, the mean for each group, effect size and 95% confidence interval were calculated, and a t-test was performed to determine if between-group differences were statistically significant.
Data for all three primary outcomes was provided from a total of 254 runs by the 23 participants in the intervention group and a total of 289 runs by the 24 participants in the control group. Participants in the intervention group reported higher comfort scores (8.00 ± 1.41 6.96 ± 2.03, ≤ 0.0001), faster running speeds (6.27 ± 1.03 6.00 ± 1.54, = 0.013), and lower RRI rates (0.70 ± 1.01 1.21 ± 1.53, = 0.18) than those in the control group. These findings were statistically significant for comfort and running speed but not for RRI rate, with statistical significance considered if < 0.05. No adjustments were made for group differences in age, gender, tendency for RRIs or usual running speed.
This preliminary report provides evidence for orthotics use in increasing comfort levels and running speed, but no significant difference in RRI rate.
关于使用矫形器在提高舒适度、增加跑步速度以及帮助降低跑步期间受伤率方面有效性的证据有限且存在分歧。随着跑步运动越来越普及，与跑步相关的损伤（RRIs）发生率也在上升。进一步研究矫形器是否可用于帮助降低RRIs对受影响的人群将非常有益。此外，有必要澄清使用矫形器是否能提高跑步时的舒适度并有助于提高跑步速度。
研究使用Aetrex矫形器跑步是否能提高舒适度和表现，并减少跑步时的损伤。
招募年龄在18岁及以上、没有严重健康问题、没有持续性足部疼痛或畸形、一生中没有足部手术史或过去6个月内没有任何手术的跑步者，他们为自愿参与。参与者被随机分配到干预组或对照组。所有参与者都被要求完成跑步，并提供关于跑步期间舒适度、跑步时间和距离以及在8周研究期内任何RRIs的定量数据。干预组的参与者穿着Aetrex L700 Speed矫形器跑步，而对照组的参与者不穿矫形器跑步。除了干预组的参与者增加了矫形器外，所有参与者都被要求按其通常的方式跑步。本报告展示了为本研究招募的前47名参与者的初步数据。跑步速度根据跑步距离和时间计算得出，单位为英里每小时。对于每个结果变量，计算了每组的均值、效应大小和95%置信区间，并进行了t检验以确定组间差异是否具有统计学意义。
干预组的23名参与者总共进行了254次跑步，对照组的24名参与者总共进行了289次跑步，提供了所有三个主要结果的数据。干预组的参与者报告的舒适度得分更高（8.00±1.41对6.96±2.03，P≤0.0001），跑步速度更快（6.27±1.03对6.00±1.54，P = 0.013），RRIs发生率更低（0.70±1.01对1.21±1.53，P = 0.18），均优于对照组。这些结果在舒适度和跑步速度方面具有统计学意义，但在RRIs发生率方面没有统计学意义，若P<0.05则认为具有统计学意义。未对年龄、性别、RRIs倾向或通常跑步速度的组间差异进行调整。
这份初步报告为使用矫形器可提高舒适度和跑步速度提供了证据，但在RRIs发生率方面没有显著差异。
