[Purpose] The purpose of this study is to investigate the effects of incorporating active walking exercises, including dynamic movements, on the quadriceps muscle strength, disability index, pain, and static balance ability in patients who have undergone bilateral endoscopic surgery, based on changes in step count. [Method] We conducted measurements and analyses over an 8-week exercise program targeting 24 men in their 40s who were underwent bidirectional endoscopic surgery. We assessed changes in step count, isometric lumbar muscle strength, ODI, NRS pain scores, and static balance ability based on differences in the composition of the exercise program. [Result] After the intervention of an active walking exercise program that included lumbar stabilization exercises, there was a significant improvement and enhancement in lumbar muscle strength and static balance ability with the increase in step coun. [Conclusion] It has been confirmed that an exercise program incorporating active walking exercises is a structured exercise program with a positive impact on lumbar muscle function and postural balance. In the future, it is believed that this effective rehabilitation exercise program could potentially enhance the quality of life through improved physical activity for patients with various orthopedic lumbar conditions.
