“…The severity of VSN at 24 hours after stroke was a significant predictor of independent activities at 6 months [7,67]. Although patients with VSN had lower independence scores than those without VSN, the difference became smaller over time [7,31]. VSN patients showed a significant improvement during the first year for independence in personal ADL [68].…”

“…Particularly in cerebral hemorrhage, the bleeding site, level of hematoma, and age are closely related to the prognosis of USN. This symptom has been reported to be common with bleeding of more than 30 mL (14). However, there have been patients in whom USN disappeared even when the hematoma exceeded 50 mL, and all were under 50 years of age.…”

“…USN is thought to present in approximately 40% of cases with right hemisphere injury (5)(6)(7)(8)(9)(10)(11). Reports show that approximately 80% of patients with right hemisphere injury from acute stroke display USN (12)(13)(14)(15). This variation may be due to differences in the underlying cause of the lesions, time from the onset, and evaluation methods (Table 1).…”

“…However, there have been patients in whom USN disappeared even when the hematoma exceeded 50 mL, and all were under 50 years of age. In other words, the prognosis of USN due to putaminal hemorrhage can vary greatly depending on age (14). Lesions restricted to the thalamus trigger USN at a high rate in the acute phase even when the hematoma level is low (15), but are often transient, eventually disappearing (14).…”

Unilateral spatial neglect refers to a condition where patients do not react to various environmental stimuli originating from the contralateral side of a brain lesion, in the absence of other sensory or motor deficits. Consequently, activities of daily living can be adversely affected. Cerebral hemorrhage or infarction is often the cause, and approximately 80% of patients with right hemisphere injury from acute stroke show unilateral spatial neglect. The presence of unilateral spatial neglect is determined through a number of different tests. However, even cases that are not apparent from typical tests are often associated with symptoms of neglect in activities of daily living. Stroke-mediated unilateral spatial neglect may improve or disappear during rehabilitation; however, in most cases, it remains. Cerebral hemorrhage, bleeding site, level of hematoma, and age are closely related with prognosis. Treatment approaches include conscious behavioral changes and activation of higher-order central nerves by stimulation from the periphery. Several mechanisms have been proposed to explain the onset of unilateral spatial neglect. Therefore, treatment strategies should be formulated only after careful examination and determination of the causative mechanism specific to each patient. This will enable the rehabilitation team to provide the most appropriate support.

“…8 ) Impairment-oriented approaches include visual search training, presentation of clues to the neglected space, and prism adaptation; however, the involvement of improved USN with improved ADL function is unclear. 9 , 10 , 11 , 12 ) In self-care training, a repetitive task is recommended to help acquire compensatory movement rather than to facilitate recovery from USN. 13 ) However, these therapies are intended for egocentric spatial neglect rather than allocentric neglect.…”

Background: There are no reports on the therapeutic application of perceptive exploration activity in patients with unilateral spatial neglect (USN). This study monitored the course of acute occupational therapy using perceptive exploration activities in a patient with USN who had difficulty in manipulating tools for daily living after a stroke. Case: A 70-year-old man was admitted to our hospital for conservative treatment of hemiparesis and USN caused by stroke. He was previously diagnosed with cerebral infarction due to middle cerebral artery occlusion. His main symptoms were hemiparesis, egocentric spatial neglect in personal space and peripersonal space, and allocentric neglect, which made it difficult to use tools for daily living. Within 24 h of admission, perceptive exploration activities were initiated as the main therapy in addition to preparatory therapies, such as the facilitation of selective movement of limbs affected by paralysis. These therapies were provided over a 30-day period in 40-min sessions, 5 days a week. This treatment resulted in improved test results for the Fugl-Meyer Assessment, Bisiach’s body neglect and anosognosia scales, and the Behavioral Inattention Test. The Functional Independence Measure scores also improved with the improvement of neglect symptoms. Discussion: This case study monitored the improvements of egocentric spatial neglect and allocentric neglect during therapy using perceptive exploration activities in a patient with USN who had difficulty manipulating tools for daily living. The effectiveness of the therapy should be confirmed by increasing the sample size in future studies.
