    somatosensory signals affect the ability of effectively coordinating multimodal
    information pertaining to the postural state during movement. Therefore, this
    study aimed to investigate the impact of a compliant surface on cortico-cortical
    causal information flow during multi-joint compound movements. Fifteen healthy
    adults (7 female / 8 male, 25.9 ± 4.0 years) performed 5 × 20 repetitions of bodyweight
    squats on firm and compliant surface. Motor behavior was quantified by center
    of pressure (CoP) displacements, hip movement and the root mean square of the
    rectus femoris activity. Using source space analysis, renormalized partial directed
    coherence (rPDC) computed subject-level multivariate effective brain connectivity
    of sensorimotor nodes. Bootstrap statistics revealed significantly decreased medio-lateral
    CoP displacement (<jats:italic>p</jats:italic> &lt; 0.001), significantly increased
    velocity of medio-lateral hip motion (<jats:italic>p</jats:italic> &lt; 0.001)
    as well as significantly lower rectus femoris activity (<jats:italic>p</jats:italic> &lt; 0.01)
    in the compliant surface condition. On the cortical level, rPDC showed significantly
    modulated information flow in theta and beta frequencies for fronto-parietal edges
    (<jats:italic>p</jats:italic> &lt; 0.01) only during the concentric phase of the
    movement. The compliant surface led to increased difficulties controlling hip
    but not center of pressure motion in the medio-lateral plane. Moreover, a decreased
    activation of the prime movers accompanied by modulations of effective brain connectivity
    among fronto-central nodes may point to altered demands on sensorimotor information
    processing in presence of sensory noise when performing bodyweight squats on compliant
    surface. Further studies are needed to evaluate a potential benefit for athletic
    and clinical populations.</jats:p>@eng"
