This research aimed at comparing high-risk patterns of ACL<br />injury in dominant and non-dominant legs of males and females during<br />cutting maneuver. Participants were national and club squash players<br />including 13 females (mean age: 23.04±6.6 yr, height: 163.3±5.4 cm,<br />weight: 61.60±5 kg) and 13 males (mean age: 24.7±4.1 yr, height:<br />179.9±5.8cm, weight: 78.8±7.8 kg). In order to measure knee flexion, trunk<br />flexion, trunk lateral flexion and knee valgus angles during cutting<br />maneuver and in two phases of initial foot contact with the ground and mid<br />stance, cutting maneuver with dominant and non-dominant legs was<br />analyzed. After the markers had been installed, cutting maneuver was<br />recorded by Casio Exilim camera with 300 Hz frequency and the recorded<br />movements were analyzed by WinAnalyze software (Version D34-1). SPSS<br />(version 20) and Paired-samples t test were used to compare the angles<br />obtained by the motion analysis of dominant and non-dominant legs. The<br />results indicated that knee and trunk joint angles during cutting maneuver<br />had a significant difference between dominant and non-dominant legs of<br />females while this difference was significant in two parameters of knee and trunk flexion at initial contact among males (P􀂕0.05). These results showed that high-risk patterns of ACL injury had a higher rate of incidence in cutting maneuver with non-dominant leg. Thus ACL injury risk is higher in the cutting maneuver with non-dominant leg than dominant leg. https://jsmed.ut.ac.ir/article_36540_06971c637b67eb6d7894cb2f98205d13.pdf
