New insights into neck-pain-related postural control using measures of signal frequency and complexity in older adults

Exploring technology for clinical applications and analysis of factors associated with postural control in older adults with idiopathic neck pain

“…Statistical significance was defined as p values of <0.05. Consistent with previous studies (Quek et al, 2014;Uthaikhup et al, 2012), the results of this study showed that older adults with NP demonstrated reduced postural stability compared to those without NP. The lack of significant differences in lower limb, vestibular or visual function and also physical activity suggest that the cause of postural instability observed in the NP group may be due to NP and directly-related impairments.…”

“…Noteworthy, DGI scores of 19 or less have previously been shown to indicate increased fall risk in older adults . When we dichotomized the DGI scores to more than 19 (low fall risk) or 19 or less (high fall risk), we found that the NP group had twice the proportion of older adults in the group with higher fall risk compared to healthy controls, supporting previous assertions that older adults with NP are at a higher risk of falls (Quek et al, 2014). It is not surprising then that older adults with NP scored lower on the ABC scale, consistent with a previous study (Uthaikhup et al, 2012), indicating that this group of older adults demonstrate reduced balance confidence compared to older adults without NP.…”

“…Individuals with NP have demonstrated sensorimotor disturbances, amongst which is the negative impact of NP on postural stability (Treleaven, 2008). Of greater relevance is that older adults with NP have demonstrated poor dynamic postural stability which places them at a higher risk of falls (Quek et al, 2014). Given the potential serious consequences of falls and the burden it imposes on public health (Hartholt et al, 2011), this highlights the need for a comprehensive assessment to inform intervention for this population.…”

After each trial, the examiner repositions the head to the NHP.…”

Which biomechanical models are currently used in standing posture analysis?

“…When concluding that electrical stimulation of one knee joint stabilizes posture [58], it would be worth checking whether this is due to a diminished knee joint motion. Similarly, when studying postural control in the presence of neck pain [77], upper body posture evaluation would help, as it has been previously demonstrated that the simple fact of bending the head forward can have an effect on CoP displacement, even in healthy subjects [83]. In the same way, in many studies, the goal is to assess the consequence of a modified kinematics or kinetics condition.…”
