23 November 2009	Amended	Contact details updated.
3 June 2008	Amended	Converted to new review format.
19 February 2008	New citation required but conclusions have not changed	Conclusions: There was moderate evidence that lumbar supports are not more effective than no intervention or training in prevention of low‐back pain, and conflicting evidence whether lumbar supports are effective as supplement to another preventive intervention. It is still unclear if lumbar supports are more effective than no or other interventions for treatment of low‐back pain.
30 December 2006	New search has been performed	There are some differences between the previous systematic review (Van Tulder 2000; Jellema 2001) and this update: Changes in this updated review include: ‐ Only RCTs are included; non‐randomized trials that were included in the previous review were excluded from this update (Anderson 1993; Thompson 1994). ‐ Two new studies on prevention (Kraus 2002; Roelofs 2007) and two new studies on treatment (Dalichau 2000; Gibson 2002) were found. ‐ Assessment of clinical relevance is new. ‐ A new comparison was added: lumbar support as supplement to another type of treatment versus that other type of treatment.
