Significant improvements seen in accelerometer-measured physical activity after lumbar spine surgery

Significant improvements seen in accelerometer-measured physical activity after lumbar spine surgery
May 23, 2017

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.
