“…First, merging of these synergies and, thereby, increasing the extent of coactivation, may serve to improve the stance limb stability and decrease pain sensation during stance (23,24,26,87,88). Several studies on PWHA have reported a reduced postural stability during bipedal, unipedal, and transition tasks (89)(90)(91). In addition, the chronic group experienced pain during walking (Table 1).…”

It is currently unknown if modular reorganization does occur if not the central nervous system, but the musculoskeletal system is affected. The aims of this study were to investigate (I) the effects of an artificial knee joint constraint on the modular organization of gait in healthy subjects; (II) the differences in modular organization between healthy subjects with an artificial knee joint constraint and people with a similar but chronic knee joint constraint. Eleven healthy subjects and eight people with a chronic knee joint constraint walked overground at 1 m/s. The healthy subjects also walked with a constraint limiting knee joint movement to 20°. The total variance accounted (tVAF) for one to four synergies and modular organization were assessed using surface electromyography from eleven leg muscles. The distribution of number of synergies were not significantly different between groups. The tVAF and the motor modules were not significantly affected by the artificial knee constraint. A higher tVAF for one and two synergies, as well as merging of motor modules were observed in the chronic knee constraint group. We conclude that in the short-term a knee constraint does not affect the modular organization of gait, but in the long-term a knee constraint results in modular reorganization. These results indicate that merging of motor modules may also occur when changes in the mechanics of the musculoskeletal system is the primary cause of the motor impairment.

“…Postural control has been evaluated under the dual-task paradigm to understand the role of cognitive processes; most studies assessed static or dynamic postural control as a primary task and cognitive task as a secondary task [2,[5][6][7].…”

Influence of Cognitive Task Difficulty in Postural Control and Hemodynamic Response in the Prefrontal Cortex during Static Postural Standing

In daily life, we perform several tasks simultaneously, and it is essential to have adequate postural control to succeed. Furthermore, when performing two or more tasks concurrently, changes in postural oscillation are expected due to the competition for the attentional resources. The aim of this study was to evaluate and compare the center of pressure (CoP) behavior and the hemodynamic response of the prefrontal cortex during static postural standing while performing cognitive tasks of increasing levels of difficulty on a smartphone in young adults. Participants were 35 healthy young adults (mean age ± SD = 22.91 ± 3.84 years). Postural control was assessed by the CoP analysis (total excursion of the CoP (TOTEX CoP), displacements of the CoP in medial–lateral (CoP-ML) and anterior–posterior (CoP-AP) directions, mean total velocity displacement of CoP (MVELO CoP), mean displacement velocity of CoP in medial–lateral (MVELO CoP-ML) and anterior–posterior (MVELO CoP-AP) directions, and 95% confidence ellipse sway area (CEA)), the hemodynamic response by the oxyhemoglobin ([oxy-Hb]), deoxyhemoglobin ([deoxy-Hb]), and total hemoglobin ([total-Hb]) concentrations using a force plate and functional near-infrared spectroscopy (fNIR), respectively. The results showed that the difficult cognitive task while performing static postural standing caused an increase in all CoP variables in analysis (p < 0.05) and of [oxy-Hb] (p < 0.05), [deoxy-Hb] (p < 0.05) and [total-Hb] (p < 0.05) compared to the postural task. In conclusion, the increase in the cognitive demands negatively affected the performance of the postural task when performing them concurrently, compared to the postural task alone. The difficult cognitive task while performing the postural task presented a greater influence on postural sway and activation of the prefrontal cortex than the postural task and the easy cognitive task.

“…Depending on the task, this learning can be evaluated through the number of errors or successful/failed attempts during task execution and motor skills, such as postural control performance [1]. Postural control, defined as "the act of maintaining, achieving or restoring a state of balance during any posture or activity" [2], is essential for standing and walking independently in order to carry out many daily routine and sports activities [2,3]; this control is affected in older people and in several neurological and musculoskeletal diseases [4][5][6][7][8][9].…”

“…Postural control training is important to prevent falls, and control must be regained after neurological and musculoskeletal disorders [10][11][12][13]. Unipedal stance is a common exercise to assess and improve postural control [5,[13][14][15][16][17][18]. Unipedal stance requires different configurations of the lower limbs and trunk, as well as inherent feedback from mechanoreceptors in the skin, muscle spindle, Golgi tendon organ and joint capsule [10,[19][20][21][22][23].…”

“…In addition, it has been reported that visual biofeedback based on centre of mass (COM) displacement reflects the maximal capabilities of the balance control system and generates greater effort than biofeedback based on the centre of pressure (COP) [31]. To assess postural control, accelerometry of COM has been proposed as an economical and accessible tool that evaluates postural sway and balance improvement by biofeedback [5,6,[32][33][34][35][36]. The accelerometer sensors embedded in smartphones have been proposed to have the potential to be a convenient, easy-to-use and valid tool for assessing postural control in normal and pathological populations [37][38][39][40][41].…”

The assessment of trunk sway smoothness using an accelerometer sensor embedded in a smartphone could be a biomarker for tracking motor learning. This study aimed to determine the reliability of trunk sway smoothness and the effect of visual biofeedback of sway smoothness on motor learning in healthy people during unipedal stance training using an iPhone 5 measurement system. In the first experiment, trunk sway smoothness in the reliability group (n = 11) was assessed on two days, separated by one week. In the second, the biofeedback group (n = 12) and no-biofeedback group (n = 12) were compared during 7 days of unipedal stance test training and one more day of retention (without biofeedback). The intraclass correlation coefficient score 0.98 (0.93–0.99) showed that this method has excellent test–retest reliability. Based on the power law of practice, the biofeedback group showed greater improvement during training days (p = 0.003). Two-way mixed analysis of variance indicates a significant difference between groups (p < 0.001) and between days (p < 0.001), as well as significant interaction (p < 0.001). Post hoc analysis shows better performance in the biofeedback group from training days 2 and 7, as well as on the retention day (p < 0.001). Motor learning objectification through visual biofeedback of trunk sway smoothness enhances postural control learning and is useful and reliable for assessing motor learning.
