  1. Efficacy of lumbosacralorthoses in the management of low back pain: biomechanical and clinicalcomparison of two designs J Cholewicki, DC Morrisette, AS Lee, NP Reeves, GA Seif Michigan State University and Medical University of South Carolina, USA, cholewic@msu.edu

  3. Objective • To compare the efficacy of an extensible (Mueller Adjustable Back Brace) and non-extensible (AspenQuikDraw Pro) lumbosacralorthoses (LSO) in augmenting trunk stiffness and improving physical function in patients with chronic low back pain (LBP).

  4. Mueller / Aspen rigid

  5. Design • Trunk stiffness was estimated from the trunk's response to a quick force release in trunk flexion, extension, and lateral bending. Twenty subjects performed five trials in each experimental condition: (1) No LSO, (2) Mueller LSO, and (3) Aspen LSO. An additional 63 subjects were randomized to the same 3 treatment groups Iisted above.

  6. Methodology • Subjects in the LSO conditions wore the LSOs daily. • The Oswestry Disability Index questionnaire was administered at baseline and at 2 to 3 weeks from starting treatment.

  7. Results • On average, the Aspen LSO increased trunk stiffness by 14% (P<O.O 1), while the Mueller LSO did not result in any significant change in trunk stiffness. • Patients wearing the Aspen LSO demonstrated a 14% improvement in disability (P = 0.01) • while patients wearing Mueller LSO reported a 9% improvement in disability (P = 0.18).

  8. Conclusion • A non-extensible LSO is more effective in augmenting trunk stiffness and in improving physical function in patients with chronic LBP when compared with an extensible LSO.
