Abstract

BackgroundMenopause is an aging process of the female reproductive system characterized by reduced estrogen levels. This results in increased osteoclastic activity, causing increased bone resorption and thus reduced bone mineral density (BMD). In addition to being influenced by osteoclastic activity, BMD of the lumbar vertebrae is also affected by the erector spinae muscle. The purpose of this study was to determine an association between postural scoliosis and erector spinae muscle endurance and its relation to BMD in postmenopausal women. MethodsThis was a cross-sectional study conducted on postmenopausal women, who were selected by simple random sampling among residents of Mampang Prapatan subdistrict. The postural abnormality of scoliosis was determined by physical examnation, while erector spinae muscle endurance time was assessed using a modified Biering-Sorensen technique, and BMD was measured by bone mineral densitometry, to categorize into normal, osteopenia, and osteoporosis.ResultsA total of 213 postmenopausal women with mean age of 53.52 ± 3.64 years participated in the study. The prevalence of scoliosis was 54.0%, and osteoporosis was 38.1%. The prevalence of osteoporosis was higher in women with scoliosis (48.7%) in comparison with those without scoliosis (31.6%) (p=0.411). In postmenopausal women with strong erector spinae muscle endurance the risk of of scoliosis was lower (0.76;95% Confidence Interval = 0.58 - 0.99) ConclusionsIn post menopausal women with postural scoliosis found a higher incidence of osteoporosis. High endurance of erector spinae muscle lowers the risk of scoliosis. Exercise to improve posture and increase endurance of erector spinae muscle need to be done to prevent decline of BMD.

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.
