Objective: To determine the effect of 6-week stroboscopic training on ankle gait mechanics in athletes with chronic ankle instability. Material and Methods: Thirty-nine participants were assigned to the stroboscopic group (SG, n=13), non-stroboscopic group (NSG, n=13), and control group (CG, n=13). Three-dimensional kinematic pretest gait analysis was performed with the Noraxon system. Ankle joint angles were recorded for 75 seconds while the athletes walked on a treadmill at a speed of 3.5 m/s. After the pretest, the SG performed 6 weeks of balance training with stroboscopic vision, the NSG performed 6 weeks of balance training without stroboscopic vision, and the CG received no training. Ankle gait analysis was repeated after 6 weeks. Repeated-measures analysis of variance with one between-subjects factor was performed. Results: Gait analysis revealed a significant increase in ankle dorsiflexion angle between pretest and posttest in the SG (p<0.001, ηp2=0.34). Between-group comparisons showed significantly higher dorsiflexion angle in the SG compared to the CG (p=0.001, ηp2=0.15) and NSG (p=0.002, ηp2=0.11). Gait analysis of 100 kinematic data points starting at heel strike was performed using MATLAB. The results demonstrated the increase in ankle range of motion in the SG occurred in the dorsiflexion angle during the midstance phase of gait. Conclusion: Stroboscopic glasses modulate visual feedback and may be clinically useful in allowing progressive rehabilitationtargeting the dependence on visual feedback for motor control.

Amaç: Kronik ayak bileği instabilitesi olan sporcularda 6 haftalık stroboskopik eğitimin ayak bileği yürüyüş mekaniklerine etkisinin belirlenmesidir. Gereç ve Yöntemler: Otuz dokuz sporcu gözlüklü grup (n=13), gözlüksüz grup (n=13), kontrol grup (n=13) olmak üzere 3 gruba ayrıldı. Sporculara Noraxon cihazı ile 3 boyutlu kinematik ilk test yürüyüş analizi yapıldı. Bilgisayar programına entegre olan sensörler yardımıyla koşu bandı üzerinde 3,5 m/sn hızla 75 sn yürüyen sporcuların ayak bileği eklem açı kayıtları alındı. İlk testten sonra gözlüklü grup 6 haftalık stroboskopik denge eğitimi, gözlüksüz grup 6 haftalık denge eğitimi yaptı. Kontrol grubu eğitim yapmadı. Altı hafta sonra ayak bileği yürüyüş analizi tekrarlandı. Tekrarlı ölçümlerde varyans analizi bağlı olmayan gözlemler arası faktör analizi kullanıldı. Bulgular: Yürüyüş analizi ölçüm sonuçlarında ayak bileği dorsifleksiyon açısında ilk test son test sonuçlarında, gözlüklü grup lehine anlamlı fark bulundu (p<0,001, ηp2=0,34). Gruplar arasında yapılan karşılaştırmada gözlüklü grubun sonuçlarında, kontrol grubu (p=0,001, ηp2=0,15) ve gözlüksüz gruba (p=0,002, ηp2=0,11) göre artış yönünde anlamlı fark bulundu. Ardından tespit edilen topuk vuruşu ile başlatılan 100 kinematik veri noktası MATLAB programı ile yürüyüş analizi süreci işlendi. Yürüyüş analizi sürecinde tespit edilen gözlüklü gruptaki dorsifleksiyon açısındaki artışın orta duruş fazı boyunca meydana geldiği tespit edildi. Sonuç: Görsel geri bildirimi modüle edebilen stroboskopik gözlükler, görsel geri bildirim bağlı motor kontrolü artırmayı hedefleyen ilerleyici rehabilitasyona izin verilmesinde klinik olarak yararlı olabilir.
