[ effect of C-bar Splint on hand function in 8-12 years old spastic diplegic children]

Cerebral palsy [CP] is a neurodevelopmental disorder caused by nonprogressive lesions. This disorder produces motor impairment deficits in early infancy. Hand function is essential in performing activities of daily living for everyone, including individuals with cerebral palsy. Adequate first web space is essential for web space expansion, thumb abduction, and a wide range of thumb mobility and hand function. The purpose of this study was to determine the effects of C-bar splint on hand function and strength and also wrist and thumb range of motion [ROM] of dominant hand of 8-12 years old children with spastic diplegic cerebral palsy. The design of this study was before- after and quasi-experimental. According with inclusion criteria, 8 to 12 years old children with spastic diplegia from physical - motor special school at Tehran [8 boys and 5 girls], were studied. They used a C-bar splint [40 degree of palmer abduction of thumb] for 8 weeks [6-8 hours during day and 4-6 hours at night]. In this study, hand function was evaluated by Jebsen Taylor Hand Function Test, hand strength by MIE dynamometer and thumb and wrist ROM by Goniometer. During intervention, they received routine occupational therapy program. The results of this study showed significant improvement in hand function [P=0.001], and thumb range of motion [P=0.02]. The data did not show any significant improvement in wrist ROM and hand strength. According to the result of this study, it seems that using C-bar splint can be an effective method in improvement of hand function and thumb ROM in 8-12 years old children with spastic diplegia

[Validity and reliability of Persion version of home falls and accident screening tool in Iraniaian elderly]

One of the common problems in elderly people is falling. The effort to identify environmental risk factors at home and their modifications may control falls and injury in the elderly. Home FAST as a valid and reliable screening tool is used to identify elderly at risk of falling at home and in society. International quality of life assessment [IQOLA] was used for validity and reliability of Home fast. After forward and backward translation, the questionnaire was evaluated for content validity by 5 occupational therapists. Sixty participants aged over 65 were randomly selected through five geographical regions of Tehran. Inter-rater and test-retest with one week interval were conducted by two occupational therapists. Agreement among experts about the validity of screening tool of Home FAST [x[2]= 25.008] were more than 96%.The correlations of test-retest with relative and absolute coefficients were high [ICC = 0.72 and SEM = 0.89]. Also, the correlation coefficients between the raters with absolute and relative [ICC = 0.88 and SEM = 0.54] were significant, indicating the high reliability of this test. This study shows the reliability and validity of the test are high. Since, test items are conformable to fall prevention goals, these results can be expected. The tool can be used by professionals

effect of verbal instructions on allocation of attention on postural control in young adults

The importance of cognitive resources was shown in dual task studies of postural control. However, there was no definite evidence on how verbal instructions influence the allocation of attention to postural control. Therefore, the objective of this study is to explore the effect of verbal instructions on postural performance. this Cross-sectional study was performed in 20 young adults [23.95 +/- 3.31]. Parallel standing/ hard surface, parallel standing/ foam surface, tandem standing/ hard surface were used as postural tasks and the choice reaction time task were conducted as cognitive task. Dual- task performance was measured under three different instructions including to pay attention to cognitive task, to postural task, and equal attention to both tasks. Comparing the performance of postural tasks under three different instructions were conducted by One-way ANOVA and showed in parallel standing on hard surface [p=0.831], parallel standing on foam [p=0.433], tandem standing on hard surface [p=0.912] for path length of COP and instructions in parallel standing on hard surface [p=0.308], parallel standing on foam [p=0.414], tandem standing on hard surface [p=0.867] for mean velocity were not significant. Postural performance in single and dual task conditions was significant only in parallel standing/ foam surface [p=0.046]. various instructions could not influence the amount of attention allocated to automatic postural tasks
