This study aimed to determine whether the synchronous and asynchronous push-up tele-assessment in individuals with spinal cord injury (SCI) is feasible and valid and to identify the relationship between the participants' self-reported asynchronous strength tele-assessment and asynchronous push-up tele-assessment.
Cross-sectional study.
Thirty-three men and women with SCI were included in this study. The participants were assessed using the one-maximum repetition test (1RM), the maximum repetitions with 60% of 1RM (MRT) of the bench press exercise, and synchronous and asynchronous push-up tele-assessment. The videos and the total repetitions performed were recorded. The primary outcomes were 1RM, MRT, synchronous push-up tele-assessment and asynchronous volume loads, and the participants' self-reported asynchronous strength tele-assessment volume load.
The synchronous push-up tele-assessment and asynchronous volume loads presented significant correlations with 1RM (0.73 and 0.45, < 0.001, respectively) and MRT volume loads (0.87 and 0.66, < 0.001, respectively). The asynchronous push-up tele-assessment presented significant correlations with the synchronous version (intraclass correlation coefficient, ICC = 0.86; 95% CI: 0.72-0.93, < 0.001) and participants' self-reported asynchronous strength tele-assessment volume loads (ICC = 0.88; 95% CI: 0.75-0.94, < 0.001). The difference between the synchronous push-up tele-assessment and asynchronous volume load means was 254.9 kg, and the interval around the differences was 1856.1 kg. The difference between asynchronous push-up tele-assessment and participants' self-reported asynchronous strength tele-assessment means was -239.4 kg, and the interval around these was 1884.1 kg.
The synchronous push-up tele-assessment is a feasible and valid way to assess the maximum resistance strength of individuals with SCI. Although the asynchronous push-up tele-assessment demonstrated excellent and significant correlations with the synchronous push-up tele-assessment and participants' self-reported asynchronous strength tele-assessment, the test repetitions and the volume loads were underestimated by 15.5% (synchronous push-up tele-assessment vs. asynchronous) and overestimated by 17.3% (asynchronous push-up tele-assessment vs. participants' self-reported asynchronous strength tele-assessment), and the effect sizes ranged from 0.19-0.38. The authors suggest emphasizing the criteria of repetition validity to reduce test error.
本研究旨在确定对脊髓损伤（SCI）患者进行同步和异步俯卧撑远程评估是否可行和有效，并确定参与者的异步力量远程评估和异步俯卧撑远程评估之间的关系。
横断面研究。
本研究纳入了 33 名男性和女性 SCI 患者。使用 1 次最大重复测试（1RM）、卧推练习的 60% 1RM 的最大重复次数（MRT）和同步和异步俯卧撑远程评估对参与者进行评估。记录视频和完成的总重复次数。主要结果是 1RM、MRT、同步俯卧撑远程评估和异步体积负荷，以及参与者的自我报告的异步力量远程评估体积负荷。
同步俯卧撑远程评估和异步体积负荷与 1RM（分别为 0.73 和 0.45，均 < 0.001）和 MRT 体积负荷（分别为 0.87 和 0.66，均 < 0.001）呈显著相关性。异步俯卧撑远程评估与同步版本呈显著相关性（组内相关系数 ICC=0.86；95%CI：0.72-0.93，<0.001）和参与者的自我报告的异步力量远程评估体积负荷（ICC=0.88；95%CI：0.75-0.94，<0.001）。同步俯卧撑远程评估和异步体积负荷均值之间的差异为 254.9 千克，差异周围的区间为 1856.1 千克。异步俯卧撑远程评估和参与者的自我报告的异步力量远程评估均值之间的差异为-239.4 千克，差异周围的区间为 1884.1 千克。
同步俯卧撑远程评估是一种可行且有效的评估方法，可以评估 SCI 患者的最大阻力强度。虽然异步俯卧撑远程评估与同步俯卧撑远程评估和参与者的自我报告的异步力量远程评估呈显著且高度相关，但测试重复次数和体积负荷分别低估了 15.5%（同步俯卧撑远程评估与异步）和高估了 17.3%（异步俯卧撑远程评估与参与者的自我报告的异步力量远程评估），效应大小范围为 0.19-0.38。作者建议强调重复有效性标准，以减少测试误差。
