Abstract Background and Purpose. Nondistally fixated (ie, what is often referred to as “open kinetic chain” [OKC]) knee extensor resistance training appears to have lost favor for some forms of rehabilitation due partly to concerns that this exercise will irritate the extensor mechanism. In this randomized, single-blind clinical trial, nondistally fixated versus distally fixated (ie, often called “closed kinetic chain” [CKC]) leg extensor training were compared for their effects on knee pain. Subjects. Forty-three patients recovering from anterior cruciate ligament (ACL) reconstruction surgery (34 male, 9 female; mean age=29 years, SD=7.9, range=16–54). Methods. Knee pain was measured at 2 and 6 weeks after ACL reconstruction surgery using visual analog scales in a self-assessment questionnaire and during maximal isometric contractions of the knee extensors. Between test sessions, subjects trained 3 times per week using either OKC or CKC resistance of their knee and hip extensors as part of their physical therapy. Results. No differences in knee pain were found between the treatment groups. Discussion and Conclusion. Open kinetic chain and CKC leg extensor training in the early period after ACL reconstruction surgery do not differ in their immediate effects on anterior knee pain. Based on these findings, further studies are needed using different exercise dosages and patient groups.

Stimulation Of

When the upper extremity is injured, open kinetic chain (OKC) exercises are primarily used to increase strength and restore functional ability—the goals of rehabilitation. It is also imperative, however, that the receptors responsible for static and dynamic stabilization of the joint be trained. This can be done with closed kinetic chain (CKC) exercises. The purposes of this study were to investigate the effect of a 4-week CKC training program on the neuromuscular control of the upper extremity and to determine whether there was a significant difference between skill-dominant limb and nondominant limb stability indices. Thirty-two physically active participants (14 men, 18 women) were tested on the FASTEX 4 weeks apart. The training group's scores significantly improved, whereas the control group's scores remained the same. It was concluded that the CKC training significantly improved the training group's ability to remain stable. The results suggest that CKC training can increase the accuracy of joint position sense because of increased stimulation of the mechanoreceptors.

The Difference

The cervical ligament plays a significant role in lateral stability of the subtalar joint but has received little attention compared with other ankle and subtalar joint ligaments. The purpose of this research was twofold. First, the elongation behavior of the cervical ligament was assessed with the calcaneofibular ligament intact and cut during two different types of inversion loads (manual and mechanical). Second, inversion range of motion was determined concomitantly with inversion loading and the difference in inversion range of motion between the calcaneofibular ligament intact to cut state was compared. The mean elongation of the cervical ligament with the calcaneofibular intact was 0.58 mm (± 0.33 mm) and 0.46 mm (± 0.23 mm) for manual and mechanical methods, respectively, and 0.88 mm (± 0.37 mm) and 0.78 mm (± 0.37 mm), respectively, for the same methods in the absence of the calcaneofibular ligament. This difference was statistically significant ( P < 0.05 manually and P < 0.02 mechanically). An average increase in the inversion range of motion was noted with both methods [7.5° manually (± 2.75°) and 7.7° mechanically (± 2.95°)] after lesioning of the calcaneofibular ligament. This difference was statistically significant ( P < 0.001) for both manual and mechanical range of motion testing. The results of this study indicate that there is a significant increase in elongation of the cervical ligament in the absence of the calcaneofibular ligament during manual and mechanically applied inversion loads in a open kinetic chain. Clinical and theoretical implications of this data are discussed.
