This present study investigated perceived health status and physical activity in elderly people after lumbar surgery to assess the effect of postoperative chronic pain on perceived health status and daily living. A total of 171 people were divided into the moderate to severe pain group and the nonpain/slight pain group. Effect sizes (r) of the assessed item scores were calculated from intergroup comparisons. The r values for the perceived health status and physical activity scores were as follows: physical, 0.49; mental, 0.43; social health, 0.24; and physical activity, 0.31. Chronic pain after lumbar surgery negatively influences perceived physical/mental health and physical activity.
