To determine whether high-level athletes with patellar tendinopathy have diminished knee proprioceptive acuity.
Cross-sectional study.
University research laboratory (institutional).
Twenty-one basketball and volleyball players with patellar tendinopathy (13 men and 8 women; mean age 24.5 ± 3.6; body mass index = 22.5 ± 2.0 kg/m) and an equal number of athletes without symptoms of patellar tendinopathy injury were included in this study.
Participants underwent knee proprioception assessments on a single day. Furthermore, age, sex, height, weight, VISA-P (Victorian Institute of Sport Assessment) questionnaire sports participation, medical history, knee injuries, previous treatment, and medication were obtained.
Knee proprioception was evaluated by assessing sense of resistance, using a weight discrimination protocol, and joint position sense (JPS).
No significant differences were observed in JPS at 30 and 60 degrees of knee flexion between groups (P = 0.165 and 0.481, respectively). In regard to the ability to discriminate weight, significant differences between the 2 groups were found with the tendinopathy group showing a higher percentage of error (P = 0.009), namely when the set of incremental weights varied by 10% from the standard weight.
Athletes with patellar tendinopathy have a diminished perception of force signals required for weight discrimination, whereas JPS remains unaffected in these athletes.
确定患有髌腱病的高水平运动员的膝关节本体感觉敏锐度是否降低。
横断面研究。
大学研究实验室（机构）。
本研究纳入了21名患有髌腱病的篮球和排球运动员（13名男性和8名女性；平均年龄24.5±3.6岁；体重指数=22.5±2.0kg/m²）以及同等数量无症状髌腱病损伤的运动员。
参与者在同一天接受膝关节本体感觉评估。此外，还获取了年龄、性别、身高、体重、VISA-P（维多利亚运动评估研究所）问卷体育参与情况、病史、膝关节损伤、既往治疗和用药情况。
通过使用重量辨别方案评估阻力感和关节位置觉（JPS）来评估膝关节本体感觉。
两组在膝关节屈曲30度和60度时的JPS无显著差异（分别为P=0.165和0.481）。在重量辨别能力方面，两组之间存在显著差异，髌腱病组的错误百分比更高（P=0.009），即当增量重量组与标准重量相差10%时。
患有髌腱病的运动员对重量辨别所需的力信号感知能力降低，而这些运动员的JPS不受影响。
