Correlations Between Values of Articulation Tests and Language Tests for Children With Articulation Disorder in Korea

OBJECTIVE: To evaluate correlations between values of articulation tests and language tests for children with articulation disorder in Korea. METHODS: Data of outpatients with chief complaint of an articulation problem were retrospectively collected. Patients who underwent Urimal Test of Articulation and Phonation (U-TAP) with Assessment of Phonology and Articulation for Children (APAC), Preschool Receptive-Expressive Language Scale (PRES), or Receptive and Expressive Vocabulary Test (REVT) simultaneously were identified. Patients whose word-level percentages of correct consonants in U-TAP (UTAP_wC) were more than 2 standard deviations below the mean as diagnostic criteria for articulation disorder were selected. Those whose receptive language age (P_RLA), expressive language age (P_ELA), or combined language age (P_CLA) in PRES was delayed more than 24 months compared to their chronological age in months as diagnostic criteria for language disorder were excluded. RESULTS: Thirty-three children aged 3–6 years were enrolled retrospectively. PRES and U-TAP showed significant correlations for most of value relationships. PRES and APAC showed significant correlations for all value relationships except for receptive language age. All values of REVT were significantly correlated with all values from U-TAP, but not with any value from APAC. Articulation tests U-TAP and APAC showed significant correlations between percentages of correct consonants. Language tests PRES and REVT showed significant correlations for all value relationships. CONCLUSION: This study suggests that articulation abilities and language abilities might be correlated in children with articulation disorder.

Association of Meniscus Protrusion with Radiographic Findings and Clinical Assessment in Both Knee Osteoarthritis

OBJECTIVE: To evaluate the association of ultrasonographic (US) findings of medial meniscus protrusion (MMP) with clinical and plain radiographic assessment in knee osteoarthritis (OA). METHOD: One hundred and twenty six knees of 63 patients were studied. The degree of protrusion for each knee of patients was measured during standing by US. Radiographs were examined in order to determine whether the participants had radiographic osteoarthritis, graded using the Kellgren-Lawrence (K-L) grade. Clinical assessment was performed by recording a visual analogue scale (VAS). Correlation was obtained between the difference of VAS and MMP in the same patient. Assessment of pain, stiffness, and disability were performed by comparison of K-WOMAC index and MMP in a patient. RESULTS: Mean protrusion (mean+/-S.D.) for knees with each K-L I, II, III, and IV grade were 0.27+/-0.52 cm, 0.38+/-0.60 cm, 0.55+/-0.76 cm, and 0.75+/-0.08 cm, respectively. The difference was significant (p<0.05). Significant correlation was observed between MMP and VAS in K-L grades II (p=0.002, r=0.500) and III (p=0.002, r=0.684), also between DeltaMMP and DeltaVAS (p=0.000, r=0.558). With the K-WOMAC index, MMP were correlated with pain and stiffness (p<0.01), but not with disability score. CONCLUSION: The degree of MMP measured by US is associated with K-L grade in knee OA patients. The degree of MMP can be a reliable indicator, like K-L grade, for radiological severity of knee OA. MMP has been correlated with VAS and with subscore of pain and stiffness, but not disability in the K-WOMAC index.
