Most physicians, trainers, and therapists are accustomed to thinking of open and closed kinetic chain terminology in terms of exercise and its application in rehabilitation protocols. This terminology can also be used to describe the mechanism by which injuries occur. Categorizing upper extremity injuries in this way not only provides vital insight into the mechanism of the injuries and helps identify possible injured structures but also allows the clinician to better develop treatment protocols. In this article, this categorization is applied to common shoulder and elbow injuries to provide insight into the nature of these injuries.

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.

Closed kinetic chain exercise is a common component of lower extremity rehabilitation. It has virtually replaced open kinetic chain exercise in the treatment of some conditions. In this paper, anatomy and physiology as they relate to closed chain exercise are examined to elucidate its unique contributions to rehabilitation. Claims made about the specificity, functionality, and safety of closed kinetic chain exercise are discussed. Muscle action, the stretch–shortening cycle, joint position sense, and clinical cases are used to illustrate the distinct role of closed kinetic chain exercise in rehabilitation.

Context: Volleyball and handball players have usually been studied collectively as “overhead athletes,” since throwing present similarities in the proximal to distal movement sequencing and upper limb joints ranges of motion. However, each sport presents specificities in the objectives when accelerating the ball and a variety of possible throwing techniques. Therefore, it is expected there may be differences in the shoulder and upper body physical performance between sports. Objective: The aim of this study was to determine if there are differences in shoulder muscle strength and upper body field performance tests between volleyball and handball athletes. Design: Cross-sectional. Methods: Ninety-nine volleyball and handball female athletes aged between 13 and 20 years were evaluated for isometric shoulder abductor and rotator strength (handheld dynamometer) and upper body field performance tests: Y Balance Test—Upper Quarter, modified Closed Kinetic Chain Upper-Extremity Stability Test, and unilateral and bilateral Seated Medicine Ball Throw. Results: Handball athletes presented greater shoulder internal rotation strength (between-group difference: 2.84; effect size 0.70), higher medial (between-group difference: 9.54; effect size 0.90), superolateral (between-group differences: 8.9; effect size 0.68), and composite scores (between-group difference 5.7; effect size 0.75) of the Y Balance Test—Upper Quarter and higher unilateral (between-group difference: 41.92; effect size 0.91) and bilateral (between-group difference: 46.11; effect size 0.83) Seated Medicine Ball Throw performance. Groups were not different for Closed Kinetic Chain Upper-Extremity Stability Test, external rotation, and abduction isometric strength. Conclusion: Our findings suggest that young female handball athletes present greater internal rotator strength and better performance in Y Balance Test—Upper Quarter and Seated Medicine Ball Throw compared to volleyball players. These differences may be related to the different demands required in the throwing movements performed in each sport and should be considered when assessing these populations.
