The purpose of this study was to find the effect of Lumbar stabilization muscle strength when visual feedback rehabilitation program is applied for. CLBP 46 patients(male-9, female-37) performed exercise program divided by three groups (CE, CBE, VFE group) for 8 weeks. CENTAUR(R) (designed by BFMC Systems, Germany)machine for research method was used as measurement tool. The results showed that all these three groups had had pain, which is measured by VAS. Pain was decreased implementing group exercise program(p<0.05). However there was no difference among three groups (p>0.05). Any group did not show better or worse result in term of pain. In case of muscular strength, all these three groups were improved implementing group rehabilitation program. Particulary, visual feedback rehabilitation program showed the most effect for muscular strength increase. The reason would be affect by accuracy of movement performance ability, postural reorganization and postural control reinforcement Lumbar Stabilization Exercise, coordination, static postural control, postural sway.

The purpose of this study is to examine the main muscle activities of EMG, when Taekwondo demonstration team take off for 540° turn kick, which motion occupies the most of time. For this research, three healthy members of Taekwondo demonstration team were chosen at the S university. This research also suggests efficient exercise method to Taekwondo demonstration team who want to exercise 540° turn kick. The research results are as follow : To improve the quality of taking off motion and the stability, people have to make right movement. The taking off motion occupied the most of time more than 0.4sec for the whole 540° turn kick movement and individual differences existed. The 540° turn kick consists of Spin movement and jumping movement. For the taking off movement, Tibialis anterior (TA), Rectus abdominis (RA) and Gastrocnemius (GA) are the important muscles. In conclusion, to improve the 540° turn kick skill, Gastrocnemius (GA), Soleus (SO) and Tinialis anterior (TA) is required to be trained and the muscle of lower limbs need to be trained in trained in balance as minor muscle. In addition, The exercise should not only be done the extension and flexion muscles located in anterior and posterior leg but also the adduction muscles located in left and right leg.

Spasticity, a neurological disorder secondary to a brain lesion, has a significant effect on skeletal muscle function. Architectural properties of the medial gastrocnemius muscles(MG) in post-stroke patients (n=11) were investigated using ultrasound imaging technique. While the medical gastrocnemius muscle was at rest and twitch-contracting, longitudinal ultrasound images of the MG in paretic and non-paretic sides were acquired at systematically varying ankle joint angles. We found that paretic sides showed shorter muscle fiber length, thinner thickness and smaller pennation angle compared with those of non-paretic side. These findings indicates that neural impairment due to brain damage causes the alteration of muscle architecture resulting in muscle function degradation.
