“…These findings indicate that the CKC exercise can improve lower-limb muscle strength in chronic stroke patients, and this may carry over into an improvement in functional performance 22 ) . A previous study analyzed the effects of a stable versus an unstable base of support on shoulder muscle activity during CKC exercise; the CKC exercise with an unstable base of support did not increase the muscle activity in comparison to the CKC exercises with a stable base of support 6 ) .…”

[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 increased once after two weeks. The muscle activity of the tibialis anterior, gastrocnemius, tibialis posterior, and peroneus longus muscles were measured. The collected data were analyzed with two-way repeated measures ANOVA. [Results] In the results for muscle strength, both groups showed significant differences in dorsiflexion and plantar flexion between the pre-test and post-test. In the results for muscle activity, no significant differences were noted for either group. [Conclusion] Open and closed kinetic-chain exercises can help to improve muscle strength.

“…Function was measured using the cervical NDI and cervical range of motion (CROM) was determined using a cervical tilt sensor to directly record the range of motion 7 ) . Upper limb stability was measured using a closed kinetic chain test (CKCT) to test the stability of the shoulder 8 ) . The subjects were randomized into either the shoulder stabilization exercise group (SSEG) or the control group, with 15 people in each.…”

[Purpose] The objective of this study was to investigate the effects of shoulder stability exercise on pain and function in neck pain patients. [Subjects] The study design consisted of a shoulder stability exercise group and a control group. [Methods] The effects of the therapies were evaluated using a visual analog scale of pain, a pressure pain threshold, neck disability index, cervical range of motion, and a closed kinetic chain test. Each group received treatment five times per week for 4 weeks. [Results] Pain levels showed no significant differences between groups, while pain threshold in all muscles, showed significant increases for both control groups. Neck disability significantly decreased for both groups and the differences between the groups were statistically significant. Ranges of motion and limb stability were measured before and after the exercise period. Flexion, extension, and right rotation were not significantly different between groups. The results showed no significant differences in shoulder stability between the groups. [Conclusion] The use of this exercise should have pronounced effects on pain reduction and functional improvement and should also improve the quality of life in patients with neck pain.

“…The difference between these two conditions is determined by whether the terminal ending of the limb is free or fixed—for example, whether one is moving against a hard or soft surface9, 10 ) . OKC and CKC exercises generate different patterns of muscle activities and ligament forces9, 11,12,13 ) .…”

[Purpose] The purpose of the present study was to analyze the effects of open kinetic chain and closed kinetic chain exercises on the static and dynamic balance of ankle joints in young healthy women. [Subjects and Methods] Twenty women in their 20s were randomly assigned to two groups of ten women each: an open kinetic chain exercise group and a closed kinetic chain exercise group. Each group performed five sets of exercises three times per week for four weeks. Exercise intensity was increased once after two weeks. The subjects’ Romberg’s test results and their limits of stability were measured to evaluate their static and dynamic balance. The data were analyzed using a two-way repeated measures analysis of variance test. [Results] In the results of Romberg’s test, the main effect of the time showed a significant difference in the trace length with eyes closed (Effect size: d=0.97). In the result of limits of stability, the interaction effect showed a significant difference in the backward, and the main effect of the group showed a significant difference in the forward. [Conclusion] The open kinetic chain and closed kinetic chain exercises both improved the balance of the subjects. The closed kinetic chain exercise was more effective at improving the dynamic balance of young healthy women than the open kinetic chain exercise.
