Background Chronic lower back pain patients commonly present with impaired lumbar movement patterns, which may result in pain and excessive loads on the lumbar spine. A stick exercise can be effective to correct impaired movement patterns during forward bending in patients with lumbar flexion syndrome. Purpose This study investigated the effect of exercise using a stick on muscle activity of gluteus maximus and erector spinae during backward return from forward bending. Study design Comparative, repeated measures design. Methods A total of 25 male patients with lumbar extension syndrome were recruited to this study. All patients performed backward return from forward bending with and without a stick. Gluteus maximus and erector spinae surface electromyography activities during backward return from forward bending were measured. Results There was a significant difference in gluteus maximus and erector spinae muscle activities, on both sides, with versus without use of the stick. During backward return from forward bending with a stick, the activities of the right and left gluteus maximus increased significantly (p<0.05), and those of the right and left erector spinae decreased significantly (p<0.05), compared to without a stick. Conclusions This study suggests that use of a stick can minimize excessive lumbar extension during backward return from forward bending.
