Single-group repeated measures examining patients with patellofemoral pain syndrome.
To examine the effect of McConnell patellar taping on single-leg vertical jump height and knee extensor moment and power during a vertical jump and lateral step-up.
Patellar taping is used by clinicians in an attempt to maximize knee extensor function during sporting activities and rehabilitation of patients with patellofemoral pain syndrome. No studies have examined the effect of patellar taping on vertical jump height and knee extensor moment and power during a maximal vertical jump or lateral step-up.
Fourteen women (24.4 +/- 5.8 years) with unilateral patellofemoral pain performed a single-leg vertical jump and lateral step-up during 4 knee conditions: patellar tape, placebo tape, no tape, and the uninvolved knee. Maximal knee extensor moment, knee power, and vertical jump height were measured for each condition using a force platform and motion analysis system.
Analysis of variance and post hoc analyses revealed a main effect for knee condition. The patellar tape condition resulted in a greater knee extensor moment (1.57 +/- 0.32 N.m/kg) and power (3.47 +/- 0.67 W/kg) than did the no-tape (1.31 +/- 0.39 N.m/kg and 2.79 +/- 1.21 W/kg) and placebo tape (1.33 +/- 0.30 N.m/kg and 2.70 +/- 0.99 W/kg) conditions. Additional analyses showed that the vertical-jump height was significantly greater in the uninvolved lower extremity (25.69 +/- 2.66 cm) compared with the patellar tape (23.33 +/- 4.22 cm), placebo tape (23.08 +/- 4.20 cm), and no-tape (23.45 +/- 4.54 cm) conditions. The patellar tape condition did not show a different vertical jump height than the placebo or no-tape conditions.
These results suggest that patellar taping compared with no tape may improve the knee extensor moment and power during weight-bearing activities such as the lateral step-up exercise and the vertical jump.
单组重复测量研究，观察髌股疼痛综合征患者。
探讨麦康奈尔髌骨贴扎对单腿垂直跳高度以及垂直跳和侧向跨步向上运动时膝关节伸肌力矩和功率的影响。
临床医生使用髌骨贴扎，试图在体育活动以及髌股疼痛综合征患者的康复过程中使膝关节伸肌功能最大化。尚无研究探讨髌骨贴扎对最大垂直跳或侧向跨步向上运动时垂直跳高度以及膝关节伸肌力矩和功率的影响。
14名单侧髌股疼痛的女性（24.4±5.8岁）在4种膝关节状态下进行单腿垂直跳和侧向跨步向上运动：佩戴髌骨贴扎、佩戴安慰剂贴扎、不贴扎以及健侧膝关节。使用测力平台和运动分析系统测量每种状态下的最大膝关节伸肌力矩、膝关节功率和垂直跳高度。
方差分析和事后分析显示膝关节状态有主效应。与不贴扎（1.31±0.39N·m/kg和2.79±1.21W/kg）及安慰剂贴扎（1.33±0.30N·m/kg和2.70±0.99W/kg）状态相比，佩戴髌骨贴扎状态下膝关节伸肌力矩（1.57±0.32N·m/kg）和功率（3.47±0.67W/kg）更大。进一步分析表明，与佩戴髌骨贴扎（23.33±4.22cm）、安慰剂贴扎（23.08±4.20cm）和不贴扎（23.45±4.54cm）状态相比，健侧下肢的垂直跳高度（25.69±2.66cm）显著更高。佩戴髌骨贴扎状态下的垂直跳高度与安慰剂或不贴扎状态相比无差异。
这些结果表明，与不贴扎相比，髌骨贴扎可能会改善侧向跨步向上运动和垂直跳等负重活动时的膝关节伸肌力矩和功率。
