“…3 Muscle function, which is related to physical function and functional disability in subjects with different clinical conditions, has been accurately assessed with isokinetic dynamometers. 7,10,11 In PAD patients, isokinetic evaluation has also been used, 12e14 and the available evidence indicates that PAD patients present lower isokinetic strength and endurance in distal muscles compared with age-matched control subjects. 12e14 However, whether PAD affects muscle function in the proximal muscles of the lower limbs remains unknown.…”

“…Randomize kontrollü çalışmalarla, kas imbalansını gidermeye yönelik egzersiz programlarının etkili olduğu gösterilmiştir (22,23). Çeşitli çalışmalarda izokinetik egzersiz programı ile kas gücü ve enduransında artış olduğu, bunun da dinamik diz stabilizasyonunu sağladığı gösterilmiştir (14)(15)(16)(17). Biz de çalışmamızda izokinetik egzersiz grubunda pik tork, total work parametrelerinde anlamlı düzelmeler saptadık.…”

“…Kapalı kinetik zincir egzersizleri içerdiği eksantrik kasılmalarla açık kinetik zincir egzersizlerine göre daha fazla güçlendirme yapar ve 0-45 derece eklem hareket açıklığında patellofemoral eklem için güvenlidir. Kapalı ve açık kinetik zincir egzersiz programlarının etkinliğini karşılaştıran çeşitli çalışmalar her ikisinin de etkili tedavi protokolleri olduğunu göstermiştir (2,14,15,(27)(28)(29).

Objective: To investigate the difference between a home exercise program versus an isokinetic concentric quadriceps-hamstring exercise program in terms of functional capacity for the treatment of patients with patellofemoral pain syndrome. Material and Methods: This randomized study included 32 patients (39 painful knees) with patellofemoral pain. The patients were allocated in two groups as home exercise (HEG, n=14) and isokinetic exercise program groups (IEP, n=18). They were given an exercise program of 3 weeks. The functional status was examined with the Kujala scale, and knee muscle power was examined with the concentric isokinetic muscle test at 60 ve 180°/sc torque velocities. Results: A progression in Kujala score was observed within both groups, HEG and IEP, before and after the treatment. There was no difference with respect to improvement level between groups. In the assessment within the group before and after the treatment, including isokinetic muscle parameters, 60°/s angular velocity extension peak torque, flexion peak torque, agonist/antagonist ratio, 180°/s angular velocity flexion peak torque and agonist/antagonist ratio, flexion total work of İEG, 180°/s angular velocity extension total work, and flexion total work parameters of IEP were observed to be statistically significant. In the assessment between the groups, 60°/s angular velocity agonist/antagonist ratio and 180°/s angular velocity flexion total work were found to be significantly in favor of the IEP group. Conclusion: The isokinetic exercise program, despite being better in parameters of strengthening and endurance, was found to be similar with the home exercise program in clinical outcome in patients with patellofemoral pain. Key Words: Patellofemoral pain, exercise, isokinetic Özet Amaç: Patellofemoral ağrı tedavisinde, evde egzersiz programı ile izokinetik konsantrik kuadriseps-hamstring güçlendirme egzersizleri arasında, fonksiyonel düzelme açısından fark olup olmadığını araştırmaktı. Gereç ve Yöntemler: Patellofemoral ağrılı, 32 hasta (39 ağrılı diz) randomize olarak çalışmaya alındı. Evde egzersiz grubu (EEG, n=14) ve izokinetik egzersiz grubu (İEG, n=18) olarak iki gruba ayrılan hastalara, 3 hafta süre ile egzersiz programı uygulandı. Fonksiyonel düzey değerlendirme-sinde Kujala skalası, diz kas kuvveti değerlendirmesinde 60 ve 180°/s açı-sal hızlarda konsantrik izokinetik kas testi kullanıldı. Bulgular: Kujala skorunda, grup içi tedavi öncesi ve sonrası skorlar arasın-da her iki grupta da anlamlı iyileşme gözlendi. İyileşme düzeyi açısından gruplar arasında fark yoktu. İzokinetik kas parametreleri ile tedavi öncesi ve sonrası arasında yapılan grup içi değerlendirmede İEG'de; 60°/s açısal hızda ekstansiyon pik tork, fleksiyon pik tork, agonist/antagonist oranı, 180°/s açısal hızda fleksiyon pik tork, agonist/antagonist oranı, fleksiyon total work, EEG'de; 180°/s açısal hızda ekstansiyon total work, fleksiyon total work parametrelerinde istatistiksel olarak anlamlı düzelme gözlendi.

The purpose of this study was to investigate the effects of isokinetic exercise on strength, joint position sense and functionality in recreational athletes with functional ankle instability (FAI). Strength, proprioception and balance of 24 recreational athletes with unilateral FAI were evaluated by using isokinetic muscle strength measurement, ankle joint position sense and one leg standing test. The functional ability was evaluated using five different tests. These were; single limb hopping course (SLHC), one legged and triple legged hop for distance (OLHD-TLHD), and six and cross six meter hop for time (SMHT-CSMHT). Isokinetic peak torque of the ankle invertor and evertor muscles were assessed eccentrically and concentrically at test speeds of 120 degrees /s. Isokinetic exercise protocol was carried out at an angular velocity of 120 degrees /s. The exercise session was repeated three times a week and lasted after 6 weeks. At baseline, concentric invertor strength was found to be significantly lower in the functionally unstable ankles compared to the opposite healthy ankles (p < 0.001). This difference was not present after executing the 6 weeks exercise sessions (p > 0.05). Ankle joint position sense in the injured ankles declined significantly from 2.35 +/- 1.16 to 1.33 +/- 0.62 degrees for 10 degrees of inversion angle (p < 0.001) and from 3.10 +/- 2.16 to 2.19 +/- 0.98 degrees for 20 degrees of inversion angle (p < 0.05) following the isokinetic exercise. One leg standing test score decreased significantly from 15.17 +/- 8.50 to 11.79 +/- 7.81 in the injured ankles (p < 0.001). Following the isokinetic exercise protocol, all of the worsened functional test scores in the injured ankles as compared to the opposite healthy ankles displayed a significant improvement (p < 0.01 for OLHD and CSMHT, p < 0.001 for SLHC, TLHD, and SMHT). These results substantiate the deficits of strength, proprioception, balance and functionality in recreational athletes with FAI. The isokinetic exercise program used in this study had a positive effect on these parameters.
