Abstract

Alignment Knee joint alignment is a critical component in the biomechanical analysis of the body, particularly in locomotor activities such as running. Imbalance or malalignment in the knee joint can disrupt movement patterns and increase the risk of musculoskeletal injuries. In pediatric physiotherapy, early identification of lower limb posture is essential to support optimal gross motor development. This study aims to examine the relationship between knee joint alignment and running speed in children aged 4–6 years. A crosssectional design was used, involving 45 children who met the inclusion criteria. Measurement of knee alignment was performed using a goniometer to assess the quadriceps angle (Q-angle), and running speed was evaluated using a 20-meter sprint test. Statistical analysis with Spearman’s correlation revealed a significant relationship (p=0.012; r=0.373). These findings indicate that better knee joint alignment is associated with faster running speed in young children. This study underscores the importance of biomechanical evaluation in physiotherapy interventions for early childhood development.

Bahasa Abstract

Alignment Knee Joint merupakan komponen penting dalam analisis biomekanik tubuh, khususnya dalam aktivitas lokomotor seperti berlari. Ketidakseimbangan atau malalignment pada sendi lutut dapat menimbulkan gangguan gerak serta meningkatkan risiko cedera muskuloskeletal. Dalam konteks fisioterapi pediatrik, identifikasi dini terhadap postur ekstremitas bawah sangat krusial untuk mendukung perkembangan motorik kasar. Tujuan penelitian ini adalah untuk mengetahui hubungan antara alignment knee joint terhadap kecepatan berlari pada anak usia 4–6 tahun. Penelitian dilakukan dengan desain cross-sectional dan melibatkan 45 subjek anak-anak sesuai kriteria inklusi. Pengukuran dilakukan menggunakan goniometer untuk menentukan sudut Q-angle serta 20 meter sprint test untuk menilai kecepatan berlari. Hasil analisis menggunakan uji Spearman menunjukkan adanya hubungan signifikan (p=0,012; r=0,373). Hasil ini menunjukkan bahwa semakin baik keselarasan sendi lutut, maka semakin optimal kecepatan berlari yang dicapai anak. Penelitian ini memperkuat pentingnya evaluasi biomekanik dalam intervensi fisioterapi pada anak usia dini.
