The purpose of Lumbar Stabilization is to recover the ability of regulating movement of muscular strength, which currently becomes an essential approach to the treatment for lumbago. Sling exercise is a dynamic exercise and a method of active exercise for the patients to take part in their own treatment. This research is to develop the correlation between Lumbar Stabilization and muscular strength as well as Sling exercise. The subjects of this experiment are 12 healthy and normal male and female lasting for 4 weeks. EMG and Postural Med were used as measuring apparatuses. After experiment of 4 weeks exercises, there was not a meaningful result in the measured result of EMG(P>0.05), But there was a significant increase in the result of Postural Med after the experiment(P<0.05). According to this result, we can find out that there is a significant correlation between Sling exercise and muscular strength as well as Lumbar Stabilization. The increase in the lumbar region augments Lumbar Stabilization and the reaction speed of muscle power. So it recovers the stabilization of spine. This Sling exercise program is efficient for the treatment and prevention of back pain.
