THE LANDING ERROR SCORING SYSTEM BETWEEN RECREATIONAL AND COLLEGIATE FEMALE ATHLETES
Keywords:
Landing Error Scoring System / Skill Level / Female Athletes / ACL InjuryAbstract
Knee is one of the most body parts which can be injured from sport activities, especially in female. Low skill athletes had higher injury rate when compared to more skilled athletes. Thus, the Landing Error Scoring System (LESS) has been reported as a valid and reliable clinical assessment tool. LESS was used to evaluate risks for anterior cruciate ligament (ACL) injury by assess quality of jump-landing technique. The objective of this study was to find the relationship of LESS score between two groups of different skill level female athletes. Forty-four participants were recruited from female undergraduates of Mahidol University. Participants were divided into two groups due to their skill levels. Group I, thirty participants (age; 19.37 ± 1.07 yrs, height; 163.40 ± 6.38 cm, weight; 55.97 ± 8.37 kg, body mass index (BMI); 20.90 ± 2.27) and Group II, fourteen participants (age; 19.29 ± 0.91 yrs, height; 163.82 ± 4.82 cm, weight; 58.22 ± 8.99 kg, BMI; 21.66 ± 2.81). LESS videos were recorded by two cameras at 300 fps at frontal and sagittal plane. Pearson x2 test was used to find and independent between LESS score and skill levels. The significant level was set at p < 0.05
There was no independence between LESS score and skill levels (x2 = 8.899, df = 3, p = 0.031). Recreational level (group I) has higher LESS score than collegiate level (group II). The higher skilled athletes have less errors in landing due to their technique and experience in jump-landing which result in lower LESS score. In conclusion, risk for ACL injury was higher in low skill athletes.
