目的:目的是评估髌骨肌腱病患者在跳跃和功能方面的表现特征,并比较短期和中期各种肌腱病治疗的变化。作为次要目标,本研究旨在验证不同治疗组VISA-P评估的膝关节功能变化与跳跃能力之间的关系.
方法:一项双盲随机对照试验。
方法:在体育俱乐部进行招募,48例髌腱病变参与者纳入研究。参与者被随机分为:干刺(DN),经皮电解(PNE),以假针刺为对照组(CG),所有这些都与偏心运动(EE)相结合。跳跃过程中的功能和性能,包括深蹲跳跃(SJ)和反移动跳跃(CMJ),被评估。
结果:在测试前和测试后评估之间的功能存在显着差异,以及在预测试和后续评估之间,在所有三组中(p<0.001)。DN组的偏心功率有所改善(p=0.021)。在测试前和测试后的功能变化与SJ最大同心力之间发现了中等相关性(r=0.63,p<0.01,CI:0.1;0.8),CMJ最大同心力(r=0.52,p=0.05,CI:-0.01;0.8),DN组的CMJ偏心功率(r=0.63,p=0.01,CI:0.1;0.8)。
结论:偏心运动可以有效改善髌腱病变的功能,DN可以改善跳跃表现的偏心力。此外,DN组的功能增强与偏心力和同心力的跳跃性能改善相关。
OBJECTIVE: The aim is to assess performance characteristics in jumps and functionality in participants with patellar tendinopathy and compare changes with various tendinopathy treatments in the short and medium term. As a secondary objective, the study aims to verify the relationship between changes in knee functionality assessed by the VISA-P and jump capacity in the different treatment groups.
METHODS: A double-blinded randomized controlled trial.
METHODS: Recruitment was conducted at sport clubs, with 48 participants with patellar tendinopathy included in the study. Participants were randomized into groups: dry needling (DN), percutaneous electrolysis (PNE), and sham needling as the control group (CG), all combined with eccentric exercise (EE). Functionality and performance during jumps, including squat jump (SJ) and counter movement jump (CMJ), were assessed.
RESULTS: Significant differences were found in functionality between the pre-test and post-test evaluations, as well as between the pre-test and follow-up evaluations, in all three groups (p < 0.001). The DN group experienced an improvement in eccentric power (p = 0.021). A moderate correlation was found between the pre-test and post-test changes in functionality and SJ maximum concentric force (r = 0.63, p < 0.01, CI: 0.1; 0.8), CMJ maximum concentric force (r = 0.52, p = 0.05, CI: -0.01; 0.8), and CMJ eccentric power in the DN group (r = 0.63, p = 0.01, CI: 0.1; 0.8).
CONCLUSIONS: Eccentric exercise could be effective in improving functionality in patellar tendinopathy and DN could improve eccentric power in jumps performance. Moreover, the DN group experienced an increase in functionality that correlated with the improvements found in jump performance in eccentric power and concentric strength.
