The influence of HD-specific postural control impairments on gait dysfunction, from pre-manifest HD (pHD) to manifest HD (mHD), is poorly understood.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objectives:<\/jats:title>\n                    <jats:p>To explore the interplay of posture and gait in HD, we first (Aim 1) quantified the extent of deficits in postural control and gait across the spectrum of HD.

We quantified postural control using wearable sensors during sensory-challenging conditions using Jerk and Total Sway Area, and gait at self-selected pace, using outcomes of gait quality (peak swing velocity, stride length, cadence, %stance, and %swing) and stride-to-stride variability. We examined between-group differences (Aim 1) and conducted multiple regression analyses (Aim 2).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Impairments in postural control (Jerk and Total Sway Area) and gait (primarily variability) were evident in pHD and substantially increased in mHD (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      \u2009&lt;\u2009.05).
