Ön Çapraz Bağ Rekonstrüksiyonu Sonrası Iki Farklı Stabilizasyon Eğitiminin Diz Kas Kuvvet Gelişimine Etkilerinin Karşılaştırılması
Özet
The aim of this study was to investigate the effects of different kinetic chain stabilization trainings on quadriceps and hamstring strength recovery in anterior cruciate ligament reconstructed patients with hamstring tendon autograft. 52 patients were randomly allocated into 3 groups. Group 1 (n=17, age: 28.3±9.0 yrs, BMI: 24.0±3.7 kg/m2) was included in both standard rehabilitation and open kinetic chain (OKC) stabilization training in isokinetic system (ISOMED 2000); Group 2 (n=18, age: 27.3±7.8 yrs, BMI: 26.1±4.0 kg/m2) was included in both standard rehabilitation and closed kinetic chain (CKC) stabilization training in functional squat system (Monitered Rehab System), while Group 3 (n=17, age: 27.0±6.3 yrs, BMI: 24.4±3.2 kg/m2) was only included in standard rehabilitation. 2 way repeated measures of ANOVA (time by group) was used for statistical analysis. Time by group interaction was found significant for quadriceps strength recovery (F(4,98)= 2.75, p=0.03). At the end of the training, quadriceps strength of Group 1 and Group 2 was greater than Group 3 (p<0.05), whereas only the strength of Group 1 was found greater at 6 months after surgery (p=0.03). On the other hand, quadriceps strength change from 1 month to 3 months was found greater in Group 1 and Group 2 compared to Group 3 (p<0.05) but strength changes from 3 months to 6 months was not found different among groups (p=0.04)There is no significant interaction between time and group for hamstring strength recovery (F(4,98)= 1.01, p=0.40). Concentric and eccentric strength of the muscles was not found different among groups (p>0.05). As a result, for quadriceps strength recovery, stabilization trainings in OKC and CKC positions were found more effective than standard rehabilitation. Therefore, resistive hamstring quadriceps co-contraction training should be included in ACL rehabilitation program so as to increase quadriceps strength.
