The aims of this study were to cross-culturally translate and equivalence of the Gross Motor Function Measure 88 (GMFM-88) in to Persian and to evaluate its reliability in 50 children with Cerebral Palsy (CP). Our investigation was a none-experimental and methodological study which developed a Persian translation of the GMFM-88 based on International Quality of Life Assessment (IQLA) guidelines. Inter-rater reliability was performed by comparison of scores recorded by two expert physiotherapists in a blind pattern while inter-rater reliability was assessed by comparison of scores recorded by an expert physiotherapist in two continuous weeks. Intra-class Correlation Coefficient (ICC) was used to evaluate both reliabilities. Additionally internal consistency was calculated using Cronbach's alpha coefficient. The ICC was 0.99 for both inter-rater reliability and intra-rater reliability with 95% Confidence Interval (CI) = 0.99-1. Cronbach's alpha coefficients for all dimensions of the GMFM-88 were ranged 0.78-0.94, which showed an acceptable internal consistency. The Persian version of the GMFM-88 which indicated high internal consistency is a reliable instrument to quantify gross motor function in children with CP and to follow efficacy of various rehabilitation and medical treatments in these patients.

In order to achieve higher compression performance the¯delity range extension (FRExt) amendment was added to the H.264 advanced video coding (AVC) standard. It uses both 4 Â 4 and 8 Â 8 integer discrete cosine transform (DCT) adaptively in the high pro¯les. This led to additional complexity of the initial version of the H.264/AVC encoder which had substantially high computational complexity. In this paper, we propose a new algorithm which reduces the computational complexity for software implementation of horizontal 8 Â 8 integer DCT by more than 25%. Simulation results indicate 22% reduction in the computation time by using the proposed algorithm.
