Purpose The purpose of this study was to investigate the effects of lumbar stabilization training on postural stability and gait in stroke patient. Methods Subjects were recruited 30 patients with stroke. They were randomly assigned to either the study group or control group. Both groups received equal amount of intervention sessions for 30 minutes a day, 3 times a week for 8 weeks. Lumbar alignment was measured using flexible ruler, muscle activity was measured using surface EMG, and gait characteristics were measured using 10m walk test. Results The study group showed significant changes in lumbar alignment, muscle activities in erector spinae muscle, hamstring muscle, and gait of the stroke patient. Conclusion Based on results of this study, lumbar stabilization training was effective therapeutic approach in improving postural stability and gait improvement in stroke patients.
