“…The cognitive performance of the LBP group in the SBT was impaired compared with that in the HC group only in the one-leg stance rather than other two postural tasks. This nding was consistent with those reported by Etemadi 13 et al and Salavati 14 et al Both of these two studies showed the LBP group had worse performance in cognitive task compared to the control group.In Etemadi 13 et al's study the reaction times of cognitive task of LBP participants were slower than those of the controls in all conditions. While in Salavati 14 et al's study more cognitive errors were found in the LBP group than control group when the cognitive task was most di cult with higher postural di culty.…”

“…Some studies have shown that higher cognitive loads could reduce the PC of people with LBP in a dual-task paradigm. For instance, Etemadi et al 13 found that a LBP group had worse PC and cognitive performance under a dual-task condition than that of a control group. Nevertheless, Salavati et al 14 found that the PC of participants with LBP did not differentiate with that of a control group in the dual-task condition, but the conigitve performance of LBP group was impaired in the posutral task with higher di culty.…”

Background: PC is a strong risk factor for falling in older people, particularly in older individuals with low back pain (LBP). Cognitive involvement in postural control (PC) increases with age.However, most scholars have not considered different difficulty levels of cognitive loads when exploring the effects of cognition on PC in older patients with LBP. To investigate how different levels of cognitive loads modulate PC in older patients with LBP.Methods: This was a cross-sectional study. Twenty older women with LBP were recruited into the LBP group, and 20 healthy older women without the history of LBP were recruited into the healthy control (HC) group. Balance parameters were computed to quantify PC. All participants underwent the static balance test (SBT), which required the participant to maintain stability during standing on a force platform with or without a concurrent a cognitive task. The SBT included three levels of difficulties of posture tasks (eyes-open vs. eyes-closed vs. and one-leg stance) and three cognitive tasks (without cognitive task vs. auditory stimulation calculator task vs. serial-7s arithmetic task). Results: A repeated-measure analysis of variance (3 postural tasks × 3 congnitive tasks× 2 groups) testing the effects of the different congnitive task levels on the performance in different postural conditions.Older people with LBP had worse PC (as reflected by larger center of pressure (COP) parameters) than HCs regardless of postural or cognitive difficulties. Compared with the single task, the COP parameters of participants with LBP were larger during dual tasks, even though the difficulty level of the cognitive task was low. Larger COP parameters were shown only if the difficulty level of the cognitive task was high in HCs. Correlations between sway area/sway length and the number of falls were significant in dual tasks.Conclusion: Our findings shed light on the how cognitive loads modulate PC for older people with LBP. Compared with HCs, cognitive loads showed more disturbing effects on PC in older people with LBP, which was associated with falling.

“…A platform actuated with sudden horizontal translation perturbation with controlled stop [ 45 – 49 ] was able to significantly discriminate between low back pain and healthy control groups [ 48 ]. This method also provides a well-defined motion trajectory which can be adjusted to fit populations with impaired functions as demonstrated on post-stroke patients [ 45 , 46 ].…”

Devices and tasks involved in the objective assessment of standing dynamic balancing – A systematic literature review

2017

BackgroundStatic balancing assessment is often complemented with dynamic balancing tasks. Numerous dynamic balancing assessment methods have been developed in recent decades with their corresponding balancing devices and tasks.ObjectiveThe aim of this systematic literature review is to identify and categorize existing objective methods of standing dynamic balancing ability assessment with an emphasis on the balancing devices and tasks being used.Data SourcesThree major scientific literature databases (Science Direct, Web of Science, PLoS ONE) and additional sources were used.Study selectionStudies had to use a dynamic balancing device and a task described in detail. Evaluation had to be based on objectively measureable parameters. Functional tests without instrumentation evaluated exclusively by a clinician were excluded. A total of 63 articles were included.Data extractionThe data extracted during full-text assessment were: author and date; the balancing device with the balancing task and the measured parameters; the health conditions, size, age and sex of participant groups; and follow-up measurements.Data synthesisA variety of dynamic balancing assessment devices were identified and categorized as 1) Solid ground, 2) Balance board, 3) Rotating platform, 4) Horizontal translational platform, 5) Treadmill, 6) Computerized Dynamic Posturography, and 7) Other devices. The group discrimination ability of the methods was explored and the conclusions of the studies were briefly summarized.LimitationsDue to the wide scope of this search, it provides an overview of balancing devices and do not represent the state-of-the-art of any single method.ConclusionsThe identified dynamic balancing assessment methods are offered as a catalogue of candidate methods to complement static assessments used in studies involving postural control.

“…Patients with back pain require an additional program that can enhance balance, as their balancing ability is diminished compared with normal people. The dynamic stability exercise excites the motor organ in the brain by stimulating proprioception to maximize the balance sense and ability to maintain it, consequently improving the balancing ability of patients with chronic back pain 12 ) .…”

[Purpose] The current study attempted to examine the effects of centrifugal contraction exercise of the rectus abdominis during the isometric contraction of the transversus abdominis on pain and balance of patients with chronic back pain. [Subjects and Methods] The subjects included thirty patients who were diagnosed with back pain due to causes other than neurological by a specialist after conducting a medical precision diagnosis. The experiment was performed after evenly dividing the subjects into two groups, namely, control and experimental, using a random method. This study measured pain by using the visual analog scale. To determine the patients’ balancing ability using the Multifunktionale trainsgerate balance measurer. [Results] All groups showed a statistically significant within-group difference in visual analog scale and balance change. However, no significant between-group difference was observed in the comparison of therapy effects. [Conclusion] Strengthening the rectus abdominis can be an important factor for increasing the stability and reducing the pain of the lumbar area among patients with back pain.
