Trial Title: Comparison of Extensible and Inextensible Lumbosacral Orthoses for Lower Back Pain

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: SINGLE
- Phase: None
- Number of Arms: 3.0

Eligibility Criteria:
Inclusion Criteria:~* chief complaint of lower back pain, with or without lower extremity (LE) symptoms~* 150 subjects will be recruited from patients seeking treatment for lower back pain from spine specialty orthopaedic clinics, family practice physicians, and out-patient physical therapy clinics~Exclusion Criteria:~* Exclusion criteria are:~* previous spinal surgery~* workman's compensation or litigation is involved~* neurological disease or injury~* systemic inflammatory disease~* pulmonary disease which restricts breathing capacity~* current pregnancy~* acute fracture~* tumor or metastatic disease~* infection~* neurological disease~* the presence of pathological reflexes (e.g., Babinski)~* the presence of lower extremity pain upon cervical motion and / or the presence of two or more of the following signs of nerve compression: diminished lower extremity strength in a myotomal distribution, diminished sensation, and / or absence deep tendon reflexes.

- Gender: ALL
- Minimum Age: 18 Years
- Maximum Age: None
- Healthy Volunteers: f

Study Arms:
- Standard of Care (Type: OTHER): Medication based on physician prescriptions or overcounter use not germane to the study. Subjects also receive physical therapy for 2 weeks.
- Extensible lumbosacral orthoses plus standard of care (Type: EXPERIMENTAL): This group receives a flexible/extensible lumbosacral orthosis, one that is commonly available over the counter
- Inextensible lumbosacral orthoses and standard of care (Type: EXPERIMENTAL): This group receives an inextensible lumbosacral orthoses which leads to 14% increase in trunk stiffness compared to the other conditions.

Based on this trial design, predict the completion outcome and termination type (if applicable).
