Comparisons of postural control, proprioception, muscle strength, pain and disability between individuals with acute, subacute and chronic low back pain.

Although postural control, proprioception and pain intensity were similar between individuals with acute, subacute and chronic LBP, muscle strength and disability seem to worsen stepwise as the pain becomes chronic. Muscle strength and disability should be taken into account while evaluating and/or managing individuals with acute and subacute stages of LBP.
