"Closed-Kinetic-chain" (CKC) exercise appear to have gained popularity over more traditionally used open kinetic chain (OKC) exercises because many clinicians believe that CKC exercises are safer and more functional. The primary objective of this study was to compare isokinetic OKC and isokinetic CKC testing of the knee. Fifty healthy young subjects with ages between 18 to 34 years (19.8±3.3) performed both isokinetic OKC and CKC exercises. The CYBEX 6000 isokinetic dynamometer was used to measure open and closed concentric torque generated by the right lower extremity. The EMG activity from eight muscles of the lower extremity was monitored simultaneously for each exercise using surface electromyography. Isokinetic CKC exercises had two distinct advantages over isokinetic OKC exercises. From a biomechanical perspective, isokinetic CKC exercises are safer because they produce stresses and forces that are potentially less of a threat to healing structures. These exercises are also more functional than isokinetic OKC exercises since they involve all the lower extremity muscles.
