病例对照研究 

Study design:

Case-Control study 

研究目的:

(1)探究健康人群、FAI患者及MAI患者在完成Side-hop测试时的触地-离地时间间隔数据,筛选并明确该时间间隔的关键阈值; (2)比较MAI患者术前、术后Side-hop测试的触地-离地时间间隔数据差异及运动功能水平变化。  

Objectives of Study:

1.To explore the ground contact-to-off time interval during the Side-hop test in healthy individuals, FAI patients and MAI patients, and screen out and determine the critical threshold of the time interval. 2.To compare the differences in ground contact-to-off time interval and the changes of motor function level during the Side-hop test in MAI patients before and after surgery.
