Abstract
Introduction: Although many studies has been proposed balance as a risk factor for sports-related injury, but few researchers have used a Knee proprioception to examine this relationship. Thus the aim of this study was to determine if knee proprioception was associated with risk of lower extremity injury among Iranian young soccer Players.
Methodology: Seventy-three players (age =17/72±1/29 yr; height =176/46 ±5/40 cm; weight =67/88 ± 7/07 kg) from four teams that playing at Tehran Asia vision u-21 primer league (18-21 years old) participated in this study. Before entering the season, Proprioception was measured bilaterally at 30°, 60° and 90° knee flexion using the Biodex Isokinetic Dynamometer. Players were monitored for musculoskeletal injuries through a season (6-month period) by medical staff.
Results: Overall injury rate was 8.7 injuries/1000 player-hours. Logistic regression modeling indicated that there is no significant relation between proprioception of knee at 30⚬ (Right; OR= 1/05; 95%CI= 0/80-1/05 ; P= 0/22) ( OR= 1/02; 95%CI= 0/80-1/31 ; P= 0/82) (left; OR= 0/91; 95%CI=0/86-1/28 ; P= 0/59) ( OR= 0/95; 95%CI= 0/72-1/27 ; P= 0/77), and 60⚬ (right; OR= 1/00; 95%CI= 0/86-1/18 ; P= 0/91) ( OR= 1/01; 95%CI= 0/76-1/35 ; P= 0/92) (left; OR= 0/93; 95%CI= 0/78-1/12 ; P= 0/49) ( OR= 1/21; 95%CI= 0/90-1/62 ; P= 0/20), and at 90⚬ (right; OR= 1/08; 95%CI= 0/92-1/27 ; P= 0/31) ( OR= 1/23; 95%CI= 0/92-1/64 ; P= 0/15) (left; OR= 1/00; 95%CI= 0/74-1/35 ; P= 0.99) ( OR= 0/83; 95%CI= 0/56-1/23 ; P= 0/36) and lower extremity injuries.
Discussion: Our results showed that Knee proprioception cannot predict lower extremity Injuries in young soccer Players. An explanation of this finding could be that measuring of proprioception by the Biodex system is not functional for soccer players.
