Altered proprioceptive postural control has been demonstrated in people with non-specific low back pain
(LBP). However, the cause-effect relation remains unclear. Therefore, more prospective studies are necessary.
Proprioceptive postural control of 104 subjects was evaluated at baseline using a force plate and with
application of vibration stimulation on ankle and back muscles. Spinal postural angles were measured
with digital photographs. Psychosocial variables and physical activity were registered using questionnaires.
Ninety subjects were followed over two years concerning their LBP status, 14 were lost to
Four distinct groups were determined after two years based on pain and disability scores: never LBP, no
LBP at intake with future mild LBP, mild LBP at intake with no further LBP, LBP at intake with further episodes
of mild LBP. Risk factors for developing or sustaining LBP were calculated using logistic regression
A more ankle-steered proprioceptive postural control strategy in upright standing increased the risk for
developing or having recurrences of mild LBP within two years (Odds: 3.5; 95% CI: 1.1–10.8; p < 0.05).
Increased postural sway, altered spinal postural angles, psychosocial and physical activity outcomes were
not identified as risk factors for future mild LBP. These findings could contribute to improving the prevention
and rehabilitation of LBP.
