[Purpose] The purpose of this study is to examine the effect of calf muscle massage on ankle flexibility and balance. [Subjects and Methods] The study’s subjects were 32 healthy college students, divided into two groups according to the massage methods applied. Both groups received five-minutes of massage to each calf, making a total of ten minutes. Massage group A received effleurage, tapotement and pressure, and massage group B received effleurage, friction and petrissage. The functional reaching test and the modified one leg standing test were performed to measure the flexibility and balance of the ankles both before and after the massage application. [Results] In the functional reaching test performed after the calf muscle massage intervention, both groups showed significant increases. However, no significant differences were found between the two groups. In the modified one leg standing test, massage group A showed a significant increase in flexibility and balance after the intervention only when the left foot was used for support. Massage group B showed a significant increase when each foot was used for support. A significant difference between the groups was only observed only when the left foot was used for support. [Conclusion] Calf muscle massage may be effective for enhancing the flexibility and balance function of the ankle joint. In particular, a combined application of friction and petrissage massage techniques may be more effective for increasing ankle joint flexibility. Therefore, the application of calf massage can be considered an appropriate method for improving balancing ability.

[Purpose] This study examined postural stability and muscle activity when limitations were placed on the ankle and knee joints. [Subjects] Forty-eight healthy young adults were randomly assigned to one of three groups: a fixed-ankle group (6 males, 9 females), a fixed-ankle-and-knee group (9 males, 7 females), and a non-fixed group (7 males, 10 females). [Methods] The fixed-ankle subjects were limited using orthopedic fiberglass casting tape and elastic bandages and the fixed-ankle-and-knee subjects were additionally limited using a knee immobilizer. There were no limitations on the ankle and knee joints of the non-fixed group subjects. We measured postural stability and muscle activities of the ankle and knee muscles. [Results] There were differences in the muscle activities of the tibialis anterior, median gastrocnemius, and rectus femoris between the groups. The greatest muscle activity in the tibialis anterior was shown by the non-fixed group, and the fixed-ankle group showed the greatest rectus femoris and gastrocnemius activities. There were significant differences in the overall stability index, anterior-posterior stability index, and medial-lateral stability index. All three indices were the lowest for the non-fixed group. [Conclusion] A fixed ankle or knee reduces muscle activity which in turn lowers postural stability.

[Purpose] The purpose of this study was to determine the difference in isokinetic muscle function in football athletes with a knee injury with and without kinesio taping. [Subjects] The subjects for this study were 10 football athletes (males) with a knee injury. [Methods] Measurements were performed by using Cybex dynamometer under uniform motion before and after the application of kinesio tape to the quadriceps and hamstring muscle. Maximal concentric knee extension and flexion at three angular velocities (60°/s, 120°/s, and 180°/s) were measured. [Results] A significant difference was found in peak torque and total work of the flexion at 120°/s and 180°/s, as well as in the average power of extension at 180°/s. [Conclusion] Though it is not the main therapy for muscle function in football athletes with injury, kinesio taping was an effective adjunct therapy.

[Purpose] The purpose of this study was to investigate the changes in the muscle activities of the neck, trunk, and lower extremities when an unstable base of support and a stable base of support were used in bridging exercises. [Subjects] The subjects of this study were 14 persons in their twenties (9 Males, 5 Females, 23.3 years old, 168.7 cm, and 70.0 kg). [Methods] The subjects performed an ordinary bridging position (stable base) and a bridging position with a dynamic ball cushion (unstable base). The muscular activities of the longissimus capitis and sternocleidomastoid in the neck, the erector spinae and rectus abdominis in the trunk, the rectus femoris and lateral hamstring in the thigh, and the tibialis anterior and lateral head of the gastrocnemius in the lower leg were measured using surface electromyography. [Results] The erector spinae, lateral hamstring and gastrocnemius activities were significantly higher on the unstable base of support than on the stable one. [Conclusion] Activity of muscle groups varies according to the stability of the base of support during bridging exercises. Therefore, conducting bridging exercises with lumbar pain patients requires a gradual change from a stable to an unstable base of support.
