A Comparison of the Korean-Ages and Stages Questionnaires and Denver Developmental Delay Screening Test

OBJECTIVE: To evaluate concurrent validity between the Korean-Ages and Stages Questionnaires (K-ASQ) and the Denver Developmental Screening Test II (DDST II), and to evaluate the validity of the K-ASQ as a screening tool for detecting developmental delay of Korean children. METHOD: A retrospective chart review was done to examine concurrent validity of the screening potentials for developmental delay between the K-ASQ and the DDST II (n=226). We examined validity of the K-ASQ compared with Capute scale (n=141) and Alberta Infant Motor Scale (AIMS) (n=69) as a gold standard of developmental delay. Correlation analysis was used to determine the strength of the associations between tests. RESULTS: A fair to good strength relationship (k=0.442, p<0.05) was found between the K-ASQ and the DDST II. The test characteristics of the K-ASQ were sensitivity 76.3-90.2%, specificity 62.5-76.5%, positive likelihood ratio (PLR) 2.41-3.40, and negative likelihood ratio (NLR) 0.16-0.32. CONCLUSION: Evidence of concurrent validity of the K-ASQ with DDST II was found. K-ASQ can be used for screening of developmental delay.

Low Energy Extracorporeal Shock Wave Therapy for Stress Fracture of the Anterior Cortex of the Tibia / 대한스포츠의학회지

Anterior cortex of the tibia is one of the intractable stress fracture sites ocurring in athletes, which are result of repetitive use damage that exceeds the intrinsic ability of the bone to repair itself. It is sometimes difficulty to repair the anterior cortical stress fracture, which result in delayed union or nonunion. Extracorporeal shock wave therapy (ESWT) can be an useful method in the management of stress fracture of the anterior cortex of the tibia. We present a case of an young athlete affected by chronic stress fractures of the anterior cortex of the tibia that received low energy ESWT. The clinical result was excellent and he was able to gradually return to sports activities.
