Advice to rest in bed versus advice to stay active for acutelow-back pain and sciatica
The objective of this review is to determine the effects of advice to rest in bed or stay active for patients with acute low-back pain or sciatica.
The following comparisons will be made:
• Bed rest versus staying active
• Bed rest versus other treatments (besides staying active)
• Shorter periods of bed rest versus longer periods of bed rest
• Staying active versus other treatments (besides bed rest)
• Comparison between different forms of advice to stay active (e.g. avoiding bedrest, staying active)
