Abstract
Background and Purpose.
Individuals with stroke often present symptoms of multiple domains,
such as weakness of the affected upper extremity (UE) and unilateral
spatial neglect (USN), which are both associated with poor functional
outcome. The aims of this systematic review were to search and review
studies that investigated (1) the relationship between USN and affected
UE sensorimotor recovery poststroke and (2) the effectiveness of
sensorimotor interventions to improve the affected UE in patients with
USN.
Methods. An electronic search of databases (MEDLINE, EMBASE,
CINAHL and Cochrane CENTRAL) was conducted using a combination of the
following terms: stroke, USN, and affected UE. Studies
meeting the inclusion criteria were rated using a modified version of
the Quality Index, and relevant data were extracted.
Results. A
total of 850 studies were identified, and 14 were included; 13 studies
assessed correlations between USN and the affected UE capacity/recovery,
and 1 study assessed an intervention to improve the UE of individuals
with USN. An association between presence of USN and UE
capacity/recovery was found in most studies and USN did not interfere
with recovery of the affected UE in the single experimental study.
Conclusions.
USN is associated with poor UE motor capacity and less UE recovery
poststroke. Therefore, these impairments should be considered when
planning rehabilitation and discharge. Because USN is a well-researched
phenomenon, the lack of studies and insufficient evidence related to UE
interventions in individuals with USN was unexpected. These
interventions should be developed and researched to improve UE and
overall functional outcome poststroke.
