Results of this study that used accelerometers to measure physical activity showed patients who underwent lumbar decompression and fusion had statistically significant improvements in physical activity; however, researchers found no significant association between the improvements in physical activity and clinical outcome scores.
Ralph J. Mobbs, MD, and colleagues performed a prospective study of 30 patients who underwent lumbar spine surgery. Of these patients, 28 completed accelerometer-tracked physical activity and clinical follow-up. Investigators used a Fitbit accelerometer (Fitbit Inc.) to assess physical performance. A Fitbit activity monitor recorded preoperative and postoperative average physical activity, which included parameters such as the number of steps taken, distance traveled and calories burned. Self-reported outcome scores included the VAS, the Oswestry Disability Index (ODI) and SF-12 mental and physical component summary scores.
