目的：本研究的目的是确定一个内部和外部的注意力集中在单腿跳跃距离和膝关节运动学的患者后ACL reconstruction（ACLR）.Design：Experimental.Setting：门诊物理治疗facility.Participants：16 patients after ACLR.Main Outcome Measures：Patients received either an instruction with an internal focus or an external focus before performing a single leg hop jump.记录受伤和非受伤腿的跳跃距离、初始接触时的膝外翻角、峰值膝外翻角、初始接触时的膝屈曲角、峰值膝屈曲角、总ROM和达到峰值角的时间。一个重复的措施MANOVA被用来确定实验条件与主要结果措施作为因变量之间的显着性。结果：外部焦点组有显着较大的膝关节屈曲角在初始接触峰值膝关节屈曲，总ROM和时间峰值膝关节屈曲受伤的腿。这项研究证明了在ACLR后患者康复期间使用外部焦点的适用性，与内部注意力焦点相比，可以提高更安全的运动模式，可能有助于降低第二次ACL损伤风险。(C)2014爱思唯尔有限公司版权所有。
Objectives: The purpose of this study was to determine the effect of an internal and external attentional focus on single leg hop jump distance and knee kinematics in patients after ACL reconstruction (ACLR).Design: Experimental.Setting: Outpatient physical therapy facility.Participants: Sixteen patients after ACLR.Main Outcome Measures: Patients received either an instruction with an internal focus or an external focus before performing a single leg hop jump. The jump distance, knee valgus angle at initial contact, peak knee valgus angle, knee flexion angle at initial contact, peak knee flexion angle, total ROM and time to peak angles for the injured and non-injured legs were recorded. A repeated measures MANOVA was used to determine significance between the experimental conditions with the primary outcome measures as dependent variables.Results: The external focus group had significant larger knee flexion angles at initial contact peak knee flexion, total ROM and time to peak knee flexion for the injured legs.Conclusions: This study demonstrates the applicability of using an external focus during rehabilitation of patients after ACLR to enhance safer movement patterns compared to an internal focus of attention and subsequently may help to reduce second ACL injury risk.
