Concurrent Validity and Reliability of Two-dimensional Frontal Plane Knee Measurements during Multi-directional Cutting Maneuvers

Abstract

Background Excessive knee valgus has been strongly suggested as a contributing key factor for anterior cruciate ligament (ACL) injuries. Three-dimensional (3D) motion analysis is considered the “gold standard” to assess joint kinematics, however, this is difficult for on-field assessments and for clinical setting. Purpose To investigate the concurrent validity of 2D measurements of knee valgus angle during cutting in different directions and to explore intra-rater and inter-rater reliability of the 2D measurements. Study Design Descriptive laboratory study Method Seven recreational soccer players participated in this study. Participants performed three trials of cutting maneuvers in three different directions (30º, 60º, and 90º) with the dominant leg. Cutting maneuvers were recorded simultaneously with a video camera and a Vicon TM motion capture system. Knee valgus angle from 2D and 3D measurements at initial contact and at peak vertical ground reaction force (vGRF) were extracted. The Pearson’s correlation was used to explore the relationship between the 2D and 3D measurements, and reliability of the 2D measurements were performed using intraclass correlation coefficients (ICC). Result Significant correlations between 2D and 3D knee valgus measurements were noted for 60º ( r = 0.45) and 90º ( r = 0.77) cutting maneuvers at initial contact. At peak vGRF, significant correlations between 2D and 3D knee valgus measurements were noted for 30º, 60º, and 90º cutting maneuvers (r=0.45, r=0.74, r=0.78), respectively. Good-to-excellent intra-rater and inter-rater reliability of the 2D knee valgus measurements was observed during cutting in all directions (ICCs: 0.821-0.997). Conclusion Moderate-to-strong correlation between 2D and 3D knee valgus measurements during 60°-90° cutting maneuvers, and good-to-excellent intra-rater and excellent inter-rater reliability for the 2D measurements in the present study supports the use of 2D knee valgus measurements in the evaluation of targeted interventions, although the limitations of examining cutting maneuvers using 2D measurement in complex movement still need to be considered.

The reliability of lower limb 3D gait analysis variables during a change of direction to 90- and 135-degree manoeuvres in recreational soccer players

“…Another possible explanation for the high ICC value is that current study participants frequently perform COD manoeuvres in their sport, reducing variabilities. When comparing the present study to another study used two-dimensional analysis, the results showed that the ICC for knee abduction angle was 0.92 in 90° COD manoeuvres, which was slightly better than the current study (ICC=0.89) (46). In addition, VGRF showed a high reliability value with low measurement error in both tasks (90°, 135°) compared to other kinematics and kinetics outcomes.…”

Perbandingan Efektivitas Pemberian Kinesio Tape Lutut Terhadap Knee Valgus pada Gerak Cutting Atlet Basket Tingkat SMA di Kota Malang

“…Permainan basket banyak melakukan gerakan yang memanfaatkan kaki sehingga membuat risk of injury pada knee yang menjadi pusat tumpuan saat melakukan landing dan cutting (Anderson et al, 2016). Knee injury terjadi karena non-contact dengan mekanisme knee valgus (Irawan et al, 2022). Risk of injury pada anggota gerak bawah lebih sering dialami pada olahraga lapangan kecil dibandingkan lapangan besar pada usia SMA, hal ini berdasarkan (Chussurur, 2015).…”

“…Parameter yang digunakan dalam penelitian ini Frontal Plane Projection Angle (FPPA) dengan pengukuran 2D menggunakan aplikasi Kinovea untuk menilai pola gerak yang beresiko menimbulkan cedera. Nilai reabilitas parameter ini memiliki nilai antar penilaian (ICC kumulatif: 0.821-0.937) dan intra-penilai yang baik (ICC kumulatif: 0.970-0.987) hal ini menunjukan bahwa validitas dan FPPA (Frontal Plane Projection Angle) dengan menggunakan pengukuran 2D adalah baik (Irawan et al, 2022). Pengukuran 2D dilakukan dengan merekam menggunakan dua kamera webcam logitech resolusi 60fps dengan ketinggian 60 cm dan jarak 2 meter dari lintasan yang langsung dihubungkan ke laptop untuk langsung di olah ke dalam software kinovea.…”

“…Selanjutnya pada hari kedua responden diminta untuk melakukan stretching lebih dahulu selama 5 menit lalu dilakukan pemasangkan marker pada Spina illiaca anterior superior (SIAS), tuberositas tibialis, dan talus responden. Kemudian responden diminta berdiri pada starting point yang sudah disediakan lalu dilakukan pengambilan gambar statis sebelum responden melakukan side step cutting manuver 45° (Irawan et al, 2022). Pada proses pengambilan data, responden akan melakukan tes sebanyak 2 sesi pada setiap sesi memiliki 5 kali repetisi dan responden diberi waktu untuk istirahat selama 1 menit sesudah melakukan setiap sesi.…”
