To evaluate the reliability of the practical life space in post-stroke patients using the Korean version of the Life-Space Assessment (K-LSA) questionnaire and to assess the relationships between the K-LSA and physical function, daily activity, quality of life, and post-stroke depression.
The LSA questionnaire was translated into Korean, and the translated version was authorized by the author of the LSA questionnaire. In a cross-sectional study, the performance of the K-LSA was evaluated in 34 stroke patients (20 males and 14 females; mean age 65.11±2.39 years) who were receiving physical and occupational therapy at the outpatient clinic in the rehabilitation medicine department of a university medical center at the time of evaluation. Performances were assessed twice by one examiner at a 2-week interval to test the reliability. The patients were evaluated using the Functional Ambulation Category (FAC) scale, Functional Independence Measure (FIM) scale, and mobility subscale of the FIM to assess their relationships with the K-LSA. They were also evaluated using the EuroQol 5 Dimensions questionnaire (EQ-5D) and Geriatric Depression Scale (GDS) to determine the relationship with quality of life and post-stroke depression.
Test-retest reliability at the first (62.20±32.14) and second (63.15±32.22) assessment was 0.993 (p<0.01). The K-LSA showed significant correlations with the FAC (r=0.848, p<0.01), FIM (r=0.765, p<0.01), mobility category of the FIM (r=0.764, p<0.01), GDS (r=-0.657, p<0.01), and EQ-5D (r=0.506, p<0.01).
This study suggests that the practical life space of post-stroke patients, assessed by the K-LSA, has a significant correlation with patients' functional mobility, independence in daily activity, quality of life, and depression.

To determine the clinical characteristics and videofluoroscopic swallowing study (VFSS) findings in infants with suspected dysphagia and compare the clinical characteristics and VFSS findings between full-term and preterm infants.
A total of 107 infants (67 full-term and 40 preterm) with suspected dysphagia who were referred for VFSS at a tertiary university hospital were enrolled in this retrospective study. Clinical characteristics and VFSS findings were reviewed by a physiatrist and an experienced speech-language pathologist. The association between the reasons of referral for VFSS and VFSS findings were analyzed.
Mean gestational age was 35.1±5.3 weeks, and mean birth weight was 2,381±1,026 g. The most common reason for VFSS referral was 'poor sucking' in full-term infants and 'desaturation' in preterm infants. The most common associated medical condition was 'congenital heart disease' in full-term infants and 'bronchopulmonary dysplasia' in preterm infants. Aspiration was observed in 42 infants (39.3%) and coughing was the only clinical predictor of aspiration in VFSS. However, 34 of 42 infants (81.0%) who showed aspiration exhibited silent aspiration during VFSS. There were no significant differences in the VFSS findings between the full-term and preterm infants except for 'decreased sustained sucking.'
There are some differences in the clinical manifestations and VFSS findings between full-term and preterm infants with suspected dysphagia. The present findings provide a better understanding of these differences and can help clarify the different pathophysiologic mechanisms of dysphagia in infants.
