OBJECTIVE This study sought to determine the psychometric properties for the Loewenstein Occupational Therapy Cognitive Assessment-Second Edition (LOTCA-II) in a population of persons with schizophrenia. METHOD Sixty-four participants with schizophrenia were administered the LOTCA-II at baseline, and 43 of these were randomly selected to undertake four more standardized measures of cognitive ...

We examined the psychometric properties (internal consistency, concurrent criterion validity, and known-group validity) of the Loewenstein Occupational Therapy Cognitive Assessment (LOTCA) in people with intellectual disabilities. A total of 111 people with intellectual disabilities and 19 people with no disabilities were included. We used Cronbach's alpha, Spearman's rho, the Kruskal-Wallis te...

[Purpose] This study investigated the effects of computer-assisted cognitive rehabilitation (CACR) and repetitive transcranial magnetic stimulation (rTMS) on cognitive function in patients with stroke. [Subjects and Methods] We enrolled 20 patients and divided them into CACR and rTMS groups. CACR and rTMS were performed thrice a week for 4 weeks. Cognitive function was measured with the Korean ...

Background The LOTCA (Loewenstein Occupational Therapy Cognitive Assessment) battery is a cognitive screening test which is widely used in occupational health. However, no work has been found that explores its use in addiction treatment. Objectives of Study To explore the convergent validity of LOTCA with neuropsychological tests that assess related cerebral functional areas. Methods The LO...

[Purpose] The purpose of this study was to investigate the effect of cognitive function on Activities of Daily Living (ADL) of post-stroke patients. [Subjects] This study examined 60 stroke patients admitted to a rehabilitation department in Korea between January 2010 and October 2011. All patients were evaluated using the Modified Barthel Index (MBI), Mini-Mental State Examination (MMSE), and ...

[Purpose] The purpose of this study is to investigate the effects of a Korean computer-based cognitive rehabilitation program (CBCR) on the cognitive function and visual perception ability of patients with acute stroke. [Subjects] The subjects were 30 patients with acute stroke. [Methods] The subjects were randomly assigned to either the experimental group (EG) or the control group (CG). The EG...

BACKGROUND Little is known about the effects of low-frequency repetitive transcranial magnetic stimulation (rTMS) on dysmnesia and the impact of brain nucleotide neurotrophic factor (BDNF) Val66Met single-nucleotide polymorphism (SNP). This study investigated the impact of low-frequency rTMS on post-stroke dysmnesia and the impact of BDNF Val66Met SNP. MATERIAL AND METHODS Forty patients with...

[Purpose] The purpose of this study was to examine the effects of a physical activity program on cognitive function and ADLs in elderly people with mild dementia. [Subjects and Methods] Both groups (n=60) participated in a cognition program three times a week for 30 minutes each time over an eight-week period. In addition, the experimental group (n=30) underwent a physical activity program for ...

OBJECTIVES Because constructional ability is a crucial perceptual-motor skill that relates to daily functioning, it should be accurately assessed in clients with neurological dysfunction. This study examined three versions of the Puzzle Reproduction task (a constructional ability task) of the Loewenstein Occupational Therapy Cognitive Assessment (LOTCA) in order to determine whether a reduced-d...

OBJECTIVE To evaluate the reliability and validity of Korean version of AST (K-AST) as a bedside screening test of apraxia in patients with stroke for early and reliable detection. METHODS AST was translated into Korean, and the translated version received authorization from the author of AST. The performances of K-AST in 26 patients (21 males, 5 females; mean age 65.42±17.31 years) with stro...
