Motor Symptoms of Spatial Neglect, Also Known as "Motor Neglect" 1167

Spatial neglect (SN) is an independent, major predictor of long-term disability among stroke survivors. SN occurs at a higher rate following right brain damage compared to left brain damage, which is about 40% vs. 20%, respectively within the first 3 months post stroke. One third of these individuals continue suffering from SN at the chronic stage (> 6 months post stroke) when spontaneous improvement is highly unlikely. SN results from damage to the neural networks critical to spatial processing and attention orientation. As a result, SN disrupts basic self-care activities (e.g., grooming), impairs postural balance, and impedes navigation (e.g., unable to avoid furniture or walls when walking or using a wheelchair). It also increases the risk of falls and body injuries. Overall, SN slows functional recovery, impedes rehabilitation outcomes, and exacerbates physical disabilities.
While the visual symptoms of SN (aka “visual neglect”) are most observed, studied, and treated, motor symptoms (aka “motor neglect”) can be just as disabling for stroke survivors. Motor symptoms of SN can include impaired proprioception, visuomotor control, or movement planning, resulting in decreased movement toward the neglected side of space (directional hypokinesia), or a “spontaneous underutilization” of the contralesional limbs independent of impairments secondary to hemiparesis.
Given the emphasis on early mobilization in acute settings and on motor rehabilitation in subacute settings, it is critical that clinicians take into account the impact of motor symptoms of SN on functional outcomes. In the proposed one-hour symposium, the two speakers will focus on the mechanisms, observations, and suggested assessments for motor neglect. Attendees will be encouraged to ask questions, share experiences, and join in the discussion. Barriers to addressing motor neglect may be identified through the symposium with attendees’ input.
