Low back pain (LBP) patients have poorer postural control compared to healthy
controls, and the importance of assessing and addressing balance is a matter of
debate. In the clinic, balance is often tested by means of the one leg stand test
(OLST) while research often employs center of pressure (CoP) on a force platform.
Portable force platforms might be of clinical relevance, but their reliability
for LBP patients in a clinical setting has not been demonstrated. As LBP patients
are more dependent on vision compared to healthy controls, the ratio of tests
performed with eyes open and eyes closed (Romberg Ratio) might be of clinical
interest. This study aimed to assess postural balance in LBP patients by
analyzing intra-session reliability of CoP parameters on a portable force
platform, the Romberg Ratio, and the OLST. Furthermore, we aimed to determine
whether CoP parameters and OLST measure identical aspects of postural stability.
We examined 49 LBP patients and found acceptable reliability of the CoP
parameters' trace length and velocity, whereas reliability regarding C90 area,
the Romberg Ratio, and the OLST was poor. Correlations between the CoP parameters
and OLST were insignificant. Reliability of trace length and velocity is
acceptable and can be used as parameters when assessing CoP in LBP patients.
