Efficacy of lumbosacral orthoses in the management of low back pain: biomechanical and clinical comparison of two designs J Cholewicki, DC Morrisette, AS Lee, NP Reeves, GA Seif Michigan State University and Medical University of South Carolina, USA, firstname.lastname@example.org
Jacek Cholewicki Jacek Cholewicki, co-director of Michigan State University's Center for Orthopedic Research at Ingham Regional Orthopedic Hospital in Lansing.
Objective To compare the efficacy of an extensible (Mueller Adjustable Back Brace) and non- extensible (AspenQuikDraw Pro) lumbosacral orthoses (LSO) in augmenting trunk stiffness and improving physical function in patients with chronic low back pain (LBP).
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.
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.
