Abstract

Effect of hold and relax technique on knee joint position awareness in normal. This study investigated whether the hold and relax technique affected knee joint position awareness. Subjects (n = 40) with non-disorder knee joint were randomly allocated into the experimental group (n = 19) and control group (n = 21). This study progressed from the direct method (hold and relax for agonist) and indirect method (hold and relax for antagonist). The hold and relax technique was repeated seven seconds for the isometric contraction and five seconds for the relaxed portion. Awareness of the knee joint position was measured at knee flexion 30°, 60°, 90° and 120° with an isokinetic dynamometer. Significant differences were seen for the mean errors for 30°, 60°, 90° and 120° knee joint position awareness. However, the means showed no significant difference. This study demonstrated that the hold and relax technique has an effect on knee joint position awareness.

Abstract

This study is conducted to study distribution of DHEAs value and IGFBP3 value of children with precocious puberty in comparison with normal children and analyze correlation of their influence in precocious puberty. Study subjects were children who had visited pediatrics department of a University hospital from Jan. 2011, to Dec. 2011. Total count of the subjects was 94, with 45 male and 49 female. 54 were subjects with precocious puberty and the other 40, normal. Furthermore, gathered data were analyzed in frequency, T-test, ANOVA, and correlation test, using SPSS 19.0. In correlation analysis of DHEAs and IGFBP3 value in child with precocious puberty, correlation value of DHEAs was .442 and IGFBP-3, .464 (p < .01). Correlation coefficients were distributed comparatively low. In conclusion, when diagnosing precocious puberty, tests on sexual hormones and pituitary hormones such as LH, FSH, and ACTH besides DHEA-S and IGFBP3 tests should be performed and as such study has a small group of subjects, it should be further expanded with more cases as subjects.
