Comparison of short- and long-term outcomes for aggressive spine rehabilitation delivered two versus three times per week.

Background Context: Rehabilitation services using intensive exercise for the treatment of chronic spinal pain have traditionally been scheduled at a frequency of three times per week.

Purpose: In an attempt to reduce the cost of rehabilitation services, this study was designed to determine whether treatment offered two times per week could produce similar outcomes when compared with an established three times per week spine therapy program.

Study Design: Prospective cohort study.
