Aim: To compare open kinetic chain exercises with closed on strength of quadriceps and knee functional activity level after reconstruction ACL. Methods: The study design is randomized controlled trial. Data 36 patients was collected subjective consent: were distributed in 3 groups each group had 12 age limit from 17-39 years, treatment given for 6 weeks including days a week conventional RICE t...

this paper proposes a new mixed integer programming model for multi-item capacitated lot-sizing problem with setup times, safety stock and demand shortages in closed-loop supply chains. the returned products from customers can either be disposed or be remanufactured to be sold as new ones again. due to the complexity of problem, three meta-heuristics algorithms named simulated annealing (sa) al...

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...

Anterior cruciate ligament (ACL) reconstruction is a common surgical knee procedure that requires intensive postoperative rehabilitation by the patient. A variety of randomized controlled trials have investigated aspects of ACL reconstruction rehabilitation. A systematic review of English language level 1 and 2 studies identified 54 appropriate randomized controlled trials of ACL rehabilitation...
