Lumbar Stabilization Exercises vs Flexor Exercises in Degenerative Spondylolisthesis
Lumbar Stabilization Exercises vs Flexor Exercises in Degenerative Spondylolisthesis
The purpose of this study is to compare the effectiveness of pain control and functional
 improvement in patients with degenerative spondylolisthesis treated with "lumbar
 stabilization exercises" vs "flexor exercises (williams exercises)"
This study is a randomized controlled trial in patients with the diagnosis of degenerative
 spondylolisthesis.

 To date, it is known that lumbar stabilization exercises are an effective treatment option in
 controlling pain and improving function in patients with degenerative spondylolisthesis based
 on previous studies, but it is not known if is this a better treatment that another exercises
 routine for chronic LBP (Low Back Pain).

 The purpose is to compare the effectiveness on pain control and functional improvement of
 "lumbar stabilization exercises" vs "flexor exercises (williams exercises)".

 All clinical evaluations are performed by a single physician who is blinded to the exercises,
 and include a full medical history, physical examination, and x-ray measurement.

 After initial evaluation, patients are given a sealed envelope containing the treatment (by
 simple randomization assigned by the investigator). The envelope is opened by the physical
 therapist which schedules a monthly session and verify the correct execution of each
 exercise. Each patient receives a sheet with instructions of the exercises to continue daily
 at home.

 Scales to assess pain and function will be recorded at baseline, 4 weeks, 3 months and at 6
 months to complete the follow up.
