This literature review seeks to examine and verify the interactions and effects of Core muscles and Low Back Pain. Core or trunk are waist, pelvis, and abdomen muscles, which provide stable spine stabilization and body movement. These Core exercises are designed to show more muscle activity when performed in an unstable state, and there are various methods of exercise for Swiss ball movements, slings, and pier movements. In addition, Low Back Pain is experienced at least once in about 80% or more of the adult population. Low Back Pain There are many causes, but weakening of the lumbar trunk muscle strengthening reduces the stability of Core muscles, causing illness and pain. The interaction between these Low Back Pain and Core exercise depends on the exercise method of the previous study, but after participating in Core exercise, it is effective in improving the physical function and pain of back pain Low Back Pain. There are many causes of Low Back Pain, but Core exercise may be offered to prevent this. As a result, it is necessary to apply a lot of rehabilitation in the field of sports to systematically manage the competitiveness of athletes and the health of the general public, and to develop new training methods through verification of sustainable effects.

The purpose of this study is to analyze the effects of active core training using all kinds of tools for 12 weeks on the Senior Fitness Test (SFT) result and foot pressure of patients who receive surgical treatment and drug therapy after a stroke. The subjects of this study were 20 patients at a rehabilitation welfare center for the elderly and they were divided into a training group (11 patients) and a control group (9 patients). The exercise method was proprioceptive exercise aimed at stimulating and training somatic senses and the subjects conducted exercise using a sling on an aero-step. The measurement items included body composition test, SFT, and foot pressure and training effect was examined. The 12-week exercise led to the following result. According to the SFT analysis result, stroke patients" active core training using a togu resulted in significant differences between the training group and the control groupin sitting and standing, raising a dumbbell, walking for six minutes, holding hands behind the back, and 2.44M walking round. There was no significant difference between the training group and the control group in foot pressure analysis. To sum up this study result, trunk stabilization exercise, in other words, active core training using a togu resulted in significant improvement in functional physical strength of stroke patients and therefore it can be said that trunk stabilization exercise has an intervention effect. Although there was no significant difference in foot pressure analysis, foot pressure distribution at the neutral position was seen, which suggests that there was influence on balance. Therefore, the researcher hopes that continuous development and study of rehabilitation programs will be made through more clinical applications.
