“…The participants of two studies did not experience any pain at the time of recording [24,33,39], neither did four individuals of another [32]. While Brumagne et al [30] stated that their participants were not in an acute recurrence of NSLBP; they nevertheless reported VAS scores of 2.2 ± 1.5 and were consequently counted as in pain.…”

Over the past 20 years, the center of pressure (COP) has been commonly used as an index of postural stability in standing. While many studies investigated COP excursions in low back pain patients and healthy individuals, no comprehensive analysis of the reported differences in postural sway pattern exists. Six online databases were systematically searched followed by a manual search of the retrieved papers. The selection criteria comprised papers comparing COP measures derived from bipedal static task conditions on a force-plate of non-specific low back pain (NSLBP) sufferers to those of healthy controls. Sixteen papers met the inclusion criteria. Heterogeneity in study designs prevented pooling of the data so only a qualitative data analysis was conducted. The majority of the papers (14/16, 88%) concluded that NSLBP patients have increased COP mean velocity and overall excursion as compared to healthy individuals. This was statistically significant in the majority of studies (11/14, 79%). An increased sway in anteroposterior direction was also observed in NSLBP patients. Patients with NSLBP exhibit greater postural instability than healthy controls, signified by greater COP excursions and a higher mean velocity. While the decreased postural stability in NSLBP sufferers further appears to be associated with the presence of pain, it seems unrelated to the exact location and pain duration. No correlation between the pain intensity and the magnitude of COP excursions could be identified.

“…Based on this observation, Vuillerme and Nougier 27 suggested that expertise in sensorimotor skills can modify the interaction between postural control and mental processes. Using a similar rationale, Salavati et al 24 compared the interaction of postural and cognitive tasks between individuals with and without low back pain. Postural stability during double-limb standing on a force platform was measured by traditional center-of-pressure parameters.…”

Lateral ankle sprains are one of the most common injuries among physically active individuals, especially those who participate in soccer, basketball, and volleyball.5 Furthermore, the recurrence rate has been estimated to be as high as 80%.11 The repeated ankle injury and giving-way feelings that occur in some individuals after the first sprain lead to a condition that has been defined as functional ankle instability (FAI).10 Neuromuscular deficits are believed to have a major contribution to the development of FAI. Poor postural control, which t StUdy deSiGN: Case-control study.t oBJeCtive: To compare the effect of dualtasking on postural and cognitive performance between subjects with functional ankle instability (FAI) and a matched control group without FAI.t BaCKGroUNd: Deficit and expertise in sensorimotor functions have been proposed as factors that can modify the interference between postural control and cognition. To the authors' knowledge, no study has investigated the posture-cognition interaction in individuals with recurrent ankle sprain, an orthopaedic condition with documented sensorimotor deficits.t MethodS: Single-limb postural stability was assessed in 15 recreational athletes with FAI and 15 matched healthy athletes without FAI. Each athlete stood on a Biodex Stability System at platform stabilities of 7 and 5, while they performed or did not perform a digits-backward cognitive task. Overall stability index (OSI), anteroposterior stability index (APSI), and mediolateral stability index (MLSI) were used as measures of postural performance. t reSUltS: At stability level 5, the individuals in the FAI group had poorer postural stability compared to those in the group without FAI (OSI, P.01; MLSI, P.01). A significant increase in OSI (P.01) and MLSI (P = .02) was also demonstrated by the individuals in the FAI group during dual-task performance compared to the single-task performance.t CoNClUSioN: Subjects with FAI demonstrated poorer postural stability when tested at level 5 on the Biodex Stability System, but not at level 7. Also, the results indicate that concurrent performance of a cognitive task decreased postural stability in the subjects with FAI, suggesting an increased dependency on attentional demands for maintenance of balance in that group. Such findings highlight the need for the assessment of postural control in patients with ankle sprain to include cognitive loading.

“…23,24 Observing the center of pressure and asymmetry in the burden placed on feet in patients with LBP using objective tools, such as a stabilometric (posturographic) test, may be a precise method of monitoring the patient's condition and the ongoing progress of therapy. It also offers full control over the complex treatment process and allows the verification of scientific hypotheses during clinical studies.…”
