Background Peripheral artery disease (PAD) is a major consequence of atherosclerosis. Recently, quantitative evaluation of hyperemic arterial flow reserve measured using cuff occlusion has been identified as a method of measuring arterial stiffness. Phase-contrast MRI (PCMRI) is an extensively used and accurate technique to quantify vessel flow. The aim of this study was to assess the interobse...

The assessment of reliability and construct validity for scales used to evaluate families is potentially limited because standard coefficients are not computed appropriately using the combined responses for family members due to their possible intra-familial correlation. In this paper, we describe and demonstrate the use of linear mixed modeling to compute generalizations of such coefficients f...

background and aim: quick speech in noise (q-sin) test has popularity for evaluating speech recognition in noise. the present study has been paid to build five new persian lists with respect to all possible factors affecting the test, to determine validity of the test and to run five lists for normal hearing subjects and assessment of reliability. methods: to build lists, frequent, familiar and...

BACKGROUND Exposure to hand-held vibrating tools may cause the hand-arm vibration syndrome (HAVS). The aim was to study the test-retest reliability of hand and muscle strength tests, and tests for the determination of thermal and vibration perception thresholds, which are used when investigating signs of neuropathy in vibration exposed workers. METHODS In this study, 47 vibration exposed work...

Background: Considering the important role of understanding the childbearing motivations in counseling services about childbearing behavior, and need for applying a valid and reliable instrument to assess it in Iranian society, this study was conducted to determine Childbearing motivation. Questionnaire was validated in two versions including Persian and English. The r...

Gait and Balance Scale (GABS) consists of historical information and examination of 14 different gait and balance parameters designed to assess the severity of these functional domains. Thirty-five patients with Parkinson's disease (PD), Hoehn and Yahr stages 1-3, were tested during their "off" period. GABS items were compared to quantitative data from two computerized gait analysis instruments...

BACKGROUND Reproducibility measurements of the range of motion are an important prerequisite for the interpretation of study results. The aim of the study is to assess the intra-rater and inter-rater reproducibility of the measurement of active Range of Motion (ROM) in patients with neck pain using the Cybex Electronic Digital Inclinometer-320 (EDI-320). METHODS In an outpatient clinic in a p...

Objectives: The Percentage of vowel correct (PVC) is one of the indices in the development of articulation and phonological skills in children that can be measured with speech samples that could be extracted from the single word or connected speech tests. The aim of this study is to introduce the PVC scale in Persian speaking children and investigate its validity and reliability. Methods: Th...

Subjective assessment of footwear experience during running is critical for recommendation and design. Recently, ride perception was quantified using an eight-dimension ratings scale. Ride varied by shoe individual treadmill running. However, it unknown whether a reliable measure in circumstances other than across sessions. The purpose this study to assess the intra-runner reliability previousl...
