Patients with stroke Also called a “brain attack” and happens when brain cells die because of inadequate blood flow. What types of clients can the tool be used for? Unilateral Spatial Neglect (USN) in the near extra personal space. The SLCT has been used with English and French-speak patients.Ī Hebrew version of the SLCT has been used in some studies as part of the Behavioral Inattention Test (e.g. In what languages is the measure available? The SLCT cannot be used to differentiate between sensory neglect and motor neglect because it requires both visual search and manual exploration (Ladavas, 1994).Patients must be able to recognize letters of the alphabet to complete the test.Patients must be able to hold a pencil to complete the test (the presence of apraxia may impair this ability).80% of cases are also know as a “schemic stroke”, or the formation of a blood clot in a vessel supplying blood to the brain. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. Client suitabilityĬan be used with: Patients with stroke Also called a “brain attack” and happens when brain cells die because of inadequate blood flow. 11x 8-inch page of paper containing 6 lines with 52 letters per line and the stimulus letter H presented 104 times (53 times on left, 51 on right).Normative data has been published by sex and age, based on the results from 341 patients with lesions of the right hemisphere (Gordon, Ruckdeschel-Hibbard, Egelko, Diller, Simmens, & Langer, 1984). Commissions are rarely seen and are therefore not included in the analyses. Omissions of 4 or more have been found to be pathological (Zoccolotti, Antonucci, Judica, Montenero, Pizzamiglio, & Razzano, 1989). Presence of USN can be inferred by calculating the frequency of errors to the left or to the right from the center of the page. Higher scores indicate better performance.

The score is calculated by subtracting the number of omissions (H’s that were not crossed out) from the possible perfect score of 104 (0 to 53 on the left and 0 to 51 on the right). The time taken to complete the test is recorded. The patient is told to put a line through each H that is found on the page. The page is placed at the patient’s midline. The stimulus letter H is presented 104 times. The test consists of one 8.5 x 11 sheet of paper containing 6 lines with 52 letters per line. In-Depth Review Purpose of the measureĭeficits, and is used to evaluate unilateral spatial neglect (USN) in the near extra personal space (Diller, Ben-Yishay, Gertsman, Goodkin, Gordon, & Weinberg, 1974). The treatment often includes a visual target that the patient uses as an anchor to direct voluntary gaze control while scanning.ĭeficits, and is used to evaluate unilateral spatial neglect (USN) in the near extra personal space (Diller, Ben-Yishay, Gertsman, Goodkin, Gordon, & Weinberg, 1974). The Single Letter Cancellation Test (SLCT) is used to evaluate the presence and severity of visual scanning During this intervention the person with USN is encouraged to conduct voluntary eye movements toward the neglected visual field (usually the left side) by performing a task in that hemispace.
