title: Comparison of effectiveness of different exercise programs in treatment of failed back surgery syndrome: A randomized controlled trial.
abstract: Failed back surgery syndrome (FBSS) is a condition characterized by persistent pain following back surgeries.
  To determine the effects of different exercises programs in FBSS.
  A single-blind, randomized, controlled trial designed. One hundred participants with failed back surgery syndrome were randomly assigned to three different exercises groups (Isokinetic, Dynamic lumbar stabilization (DLS), and home exercises (HE) groups) and a control group. Patients were evaluated before and after 8-week exercise program and follow-ups at the 3rd and 6th months after the exercise program. Finger-floor distance and lumbar Schober for lumbar mobility, visual analog scale (VAS) for pain, Modified Oswestry Disability Index, Beck Depression Inventory, fear-avoidance attitudes survey, and progressive-isoinertial weight lifting test were used as follow-up parameters. Lumbar muscle strength was assessed with the isokinetic dynamometer.
  VAS levels were decreased from 67.7 to 22.8 in isokinetic and from 68.7 to 25.0 in DLS and from 64.6 to 47.1 in HE groups at the end of the program (p< 0.05). Also, all of other follow-up parameters of the isokinetic and DLS exercise groups viewed significant improvements compared to the control group.
  According to our results either isokinetic or DLS exercises are more effective in FBSS patients.
