Patellofemoral pain syndrome (PFPS) is a common ailment of the knee. Both open and closed kinetic chain exercises are effective in strengthening of the quadriceps muscle. It has been suggested that these exercises are used jointly in the management of PFPS, but no study to date has evaluated the effect of combined open and closed kinetic chain exercises on PFPS. The present randomized controlle...

OBJECTIVE To compare the effects of open and closed kinetic chain exercise on shoulder joint reposition sense. DESIGN AND SETTING Subjects with no previous upper extremity injury participated in a 6-week exercise program consisting of 3 sessions per week. SUBJECTS Thirty-nine healthy male military cadets: 13 each in the open, closed, and control groups. MEASUREMENTS Each subject was prete...

[Purpose] The purpose of this study was to analyze the effects of open and closed chain exercise on the muscle strength and muscle activity of the ankle joint. [Subjects and Methods] Twenty women in their 20s were randomly assigned to two groups: the open kinetic-chain group and the closed kinetic-chain group. Each group performed 5 sets 3 times per week for 4 weeks. Exercise intensity was incr...

[Purpose] This study investigated the effect on activities, shoulder muscle fatigue, upper limb disability of two exercise types performed by patients in the post- immobilization period of rotator cuff repair. [Subjects and Methods] The intervention program was performed by 20 patients from 6 weeks after rotator cuff repair. Ten subjects each were randomly allocated to a group performing open k...

[Purpose] This study aimed to investigate how closed and open kinetic chain exercises differed in their impact on bone mineral density (BMD) and fall risk in postmenopausal women with osteoporosis. [Subjects and Methods] The research sample consisted of 40 postmenopausal women with osteoporosis with ages between 51 and 58 years old. They were divided at random into two groups of 20 each, respec...

Due to increasing emphasis on closed kinetic chain exercises in rehabilitation, there is a need to objectively quantify their effectiveness. The purpose of this study was to determine the test-retest reliability of the peak force and total work scores during a concentric isokinetic leg press pattern using the Lido Linea closed kinetic chain isokinetic dynamometer. The static calibration of forc...

The purpose of this study was to investigate the ability of closed and open kinetic chain tests of muscular strength to assess functional performance. Sixteen healthy male subjects, with a mean (+/-SD) age, body mass and height of 27+/-5 years, 78+/-9 kg and 183+/-9 cm, respectively, volunteered to participate in the study. In the closed kinetic chain test (involving muscles working across mult...

Background: Recent discussions have compared the use of closed-chain and open-chain kinetic exercises in the management of patellofemoral pain. Literature shows disparity over the preferred method. While the clinical effectiveness of the two different approaches has been compared, there is no information in the literature on the effect of these exercise types on the vasti muscles of the thigh. ...
