Abstract

Prevalence rates for speech and language delay have been reported across wide ranges. Speech and language delay affects 5% to 8% of preschool children, often persisting into the school years.  A cross-sectional study was conducted in 208 children aged 48-59 months to determine the validity and reliability of the Indonesian edition of the Preschool Language Scale version 4 (PLS4) as a screening tool for the identification of language development disorders. Construct validity was examined by using Pearson correlation coefficient. Internal consistency was tested and repeated measurements were taken to establish the stability coefficient and intraclass correlation coefficients (ICC) for test-retest reliability. For construct validity, the Pearson correlation coefficient ranged from 0.151-0.526, indicating that all questions in this instrument were valid for measuring auditory comprehension (AC) and expressive communication skills (EC). Cronbach’s alpha level ranged from 0.81-0.95 with standard error of measurement (SEM) ranging from 3.1-3.3. Stability coefficients ranged from 0.98-.0.99 with ICC coefficient ranging from 0.97-0.99 both of which showed an excellent reliability. This study found that PLS-4 is a valid and reliable instrument. It is easy to handle and can be recommended for assessing language development in children aged 48-59 months.

Abstract

In previous studies, duration of hand exercises in patients with rheumatoid arthritis (RA) had widely varying ranges, from 3 weeks to 4 months. An experimental study was conducted to evaluate the effect of range of motion (ROM) and muscle strengthening exercises for 6 weeks on grip strength and hand function in RA patients. Seventeen patients with chronic RA were randomly assigned to a treatment group and a control group. The treatment group (n=8) was given muscle strengthening exercises and heat therapy using paraffin baths 3 times a week at the hospital and ROM exercises once a day at home for 6 weeks. The control group (n=9) was given only paraffin baths 3 times a week. After 6 weeks, there were significant differences in hand function (p=0.003), right and left grip strength (p=0.000 and p=0.001) and ROM in the interventional group only. ROM and isometric strengthening exercises significantly improved grip strength and hand function in patients with RA, while no impact was found when the patients were given paraffin baths only. In view of the small size of the study population, there is a need for further studies with larger populations.

Abstract

BACKGROUNDFoot pronation causes biomechanical abnormalities in the form of functional leg-length disparity. Foot orthoses are often used in the treatment of abnormal pronation. The aim of the study was to evaluate the effect of foot orthoses on abnormal kinematic chain the differences of pelvic height, step length, and walking distance on walking test in young women with biomechanical abnormality.METHODS A randomized double blind controlled clinical trial was conducted on 27 young adult women having abnormal biomechanical abnormalities. By random allocation the subjects were divided into the intervention group (14 subjects) receiving correction of foot pronation using foot orthoses, and the control group (13 subjects) receiving no orthoses. Before and during use of foot orthoses, we determined pelvic height difference (mm), step length difference (cm), and walking distance at maximal walking speed for 15 minutes. RESULTS Correction of foot pronation resulted in decreased pelvic height difference from 4.7 ± 2.1 mm to 1.7 ± 1.3 mm (p<0.001) and in a reduction in step length difference, from 4.9 ± 2.9 cm to 2.1 ± 1.5 cm (p=0.002). Walking test distance of the intervention group was 1318.5 ± 46.3 m, as compared with that of the control group of 1233 ± 114.7 m (p = 0.05). Walking distance of the intervention group rose steadily in the second test to 1369.3 ± 27 m, and in the third test to 1382.14 ± 10.5 m (p<0.001). CONCLUSIONS Foot orthoses improved the kinematic chain, resulting in a more symmetrical pelvic height, reduced step length difference, and increased functional walking ability.
