Purpose: Sub-acromial impingement syndrome [SIS] is one of the most common causes of shoulder pain, which affects shoulder joint proprioception. Closed kinetic chain [CKC] exercises with a Sling are more effective and safer than open kinetic chain [OKC] exercises. This study aimed to compare the efficiency of OKC and Sling exercises [TRX] on shoulder sense position joints in overhead athletes w...

BACKGROUND There is no consensus on whether closed kinetic chain (CKC) or open kinetic chain (OKC) exercises should be the intervention of choice following an anterior cruciate ligament (ACL) injury or reconstruction. METHODS A systematic search identified randomized controlled trials of OKC versus CKC exercise training in people who had undergone ACL reconstructive surgery. All published stu...

lateralis imbalance. The authors concluded that there was some evidence that exercise is effective in the treatment of PFPS, but again did not single out specific exercises. Four randomized studies (n=179) showed no difference in pain reduction with closed kinetic chain exercises (weight bearing or foot in contact with ground; eg, squats) versus open kinetic chain exercises (non–weight bearing;...

OBJECTIVE To evaluate the patellar height of volunteers with and without patellofemoral pain syndrome (PPS) during maximal voluntary isometric contraction (MVIC) in open kinetic chain (OKC) and closed kinetic chain (CKC) exercises. METHODS Twenty healthy women, and nineteen women with patellofemoral pain syndrome were evaluated and subjected to nuclear magnetic resonance imaging during rest a...

Proprioception following lower extremity injuries is commonly recommended, but there is little information on proprioception training following upper extremity injuries. No studies have evaluated whether proprioception programs for athletes in open kinetic chain activities (throwing, shot putting) should be different than programs for athletes in closed kinetic chain activities (gymnastics, swi...

Sequenced physiologic muscle activations in the upper and lower extremity result in an integrated biomechanical task. This sequencing is known as the kinetic chain, and, in upper extremity dominant tasks, the energy development and output follows a proximal to distal sequencing. Impairment of one or more kinetic chain links can create dysfunctional biomechanical output leading to pain and/or in...

Background: The purpose of this study was to investigate the ratio of Electromyography (EM G) activities of the vastus medialis obliqus (VMO) and vastus lateralis (VL) within seven angles of knee joint range of motion using isometric contraction in open kinetic chain (OK C) and closed kinetic chain (CKC). Methods: The dominant knees of 44 healthy female subjects (mean age: 24.84 with range...

Closed-kinetic chain resistance training (CKCRT) of the lower body is superior to open-kinetic chain resistance training (OKCRT) to improve performance parameters (e.g., vertical jump), but the effects of upper-body CKCRT on throwing performance remain unknown. This study compared shoulder strength, power, and throwing velocity changes in athletes training the upper body exclusively with either...
