The use of electromyography (EMG) parameters depends on their reliability. The purpose of this study was to determine the reliability of common EMG parameters recorded from muscles of lower extremity during walking on the stairs and an inclined surface.
Subjects and Fourteen healthy young males went up the stairs and an inclined surface with normal speed and after 30s rest went down. This was repeated 5 times with 1 min intervals. At the same time, surface EMG of rectus femoris, vastus medialis, vastus lateralis, and tibialis anterior muscles were recorded. In time domain, integrated EMG (IEMG) and root mean square of EMG (RMS), and in frequency domain, median frequency (MF) and mean power frequency (MPF) were calculated. Intra-class correlation coefficients and standard error of measurement for each parameter were calculated.
The average relative and normalized absolute reliability of iEMG and RMS were higher than MF and MPF. The average relative and normalized absolute reliability in going up were better than going down. In overall, there was no difference between the reliability of RMS and IEMG and also between MF and MPF.
Differed reliability of EMG parameters in various movement conditions emphasizes the need to have reliability measures for all parameters of each muscle in conducting researches.

In this study، recognition rates of consonants available in vowel-consonant-vowel structure in hearing tests and two microscopic models will be investigated. Such a syllable structure doesn’t exist in Farsi and Azerbaijani languages، but since the goal is only recognition of middle phoneme، according to hearing tests، listeners are able to properly recognize phonemes in clean speech conditions. Inasmuch as these syllable structures are meaningless، it will be suitable for our purpose that is only determination of recognition rates of phonemes not meaningful words. Using this corpus، listeners’ linguistic knowledge in prediction of words is disregarded. Results of hearing tests are compared with two microscopic models based on human auditory system. Difference between two models is at the final stage of feature extraction that in first model، a 8 Hz filter and in the second model a modulation filterbank is used. Correct recognition rates of phonemes in different signal to noise ratios and two distance metrics for speech recognizer، will be compared. In this study recognition rates of consonants for listeners with Azerbaijani native language have been studied. Beside the empirical aspect of the paper، the innovations of this work lies in the study of using two different distance measures for Holube’s model and also direct comparison of two microscopic models in prediction of overall recognition rates and recognition rate of each consonant.

Service quality is considered as a main domain of quality associ­ated with non-clinical aspect of healthcare. This study aimed to survey and im­proves service quality of delivered care in the Physiotherapy Clinic affiliated with the Tabriz University of Medical Sciences, Tabriz, Iran. A quasi experimental interventional study was conducted in the Physiotherapy Clinic, 2010-2011. Data were collected using a validated and reli­able researcher made questionnaire with participation of 324 patients and their coadjutors. The study questionnaire consisted of 7 questions about demographic factors and 38 questions for eleven aspects of service quality. Data were then analyzed using paired samples t-test by SPSS16. In the pre intervention phase, six aspects of service quality including choice of provider, safety, prevention and early detection, dignity, autonomy and availability achieved non-acceptable scores. Following interventions, all aspects of the service quality improved and also total service quality score improved from 8.58 to 9.83 (P<0.001). Service quality can be improved by problem implementation of appropriate interventions. The acquired results can be used in health system fields to create respectful environments for healthcare customers.

In flexible flat foot the medial longitudinal arch eliminates while weight bearing and it has adverse effects on lower extremity chain. The purpose of this study was to investigate the effects of flexible flat foot on lower extremities, especially in hip joint function. In this descriptive cross sectional study, 487 feet of 6-12 years old children evaluated by static foot print. 14 girls and 14 boys with grade 1 and 2 flexible flat foot were selected as case groups and 21 girls and 2 boys with no sign of flat foot were selected as control groups. The following outcomes were measured in 4 study groups: range of active and passive internal and external rotation in sitting and prone position, the strength of internal and external rotator muscles, inter condylar and inter malleollar distance, apparent and true lengths of the lower extremities and Q angle. In girls with flexible flat foot, the internal rotation of the hip was significantly increased compared with that in boy (P<0/05). Similarly, the strength of internal and external rotator muscles was decreased significantly with the amount of 1 degree in manual muscle testing grades (P<0/05). It seems that the flexible flat foot is associated with an increase in internal and external rotation of the hip in early age. This may lead to some mechanical deficits in lower extremity with aging.

Item analysis is an integrate component of course assessment which helps observe the item characteristics and improve the quality of the course exam. It also provides a guide for improving the teaching method to enhance the students’ learning outcomes. However, item analysis results may not be applied to adjust the way teachers teach and improve the items characteristics. The purpose of this study was to determine the effect of item analysis in improving assessment and teaching quality. The Item characteristics of the final exam for kinesiology course for physiotherapy students in 2 semesters were studied. Improved and good multiple choice questions (MCQs) were then conducted for another semester, followed by application of both good MCQs and improved teaching for the other semester. The item characteristics were compared to observe any effect of good MCQs and teaching on educational performance. The good MCQs along with the improved teaching were associated with the greater mean score and the students who passed the exam rather than those with only good MCQs. The percentage of easy questions (42.5%) in students who received good MCQs and improved teaching compared with those (15%) who only received good MCQs indicated that the improved pool of questions were shifted from medium to easier questions. We concluded that the item analysis should be followed by revised and improved teaching method. It appears that improved item characteristics are associated with improved teaching method and possibly with an improvement in students’ learning.

The studies indicated that patients’ rights compliance led to positive atmosphere in service delivery environment and improve in therapeutic results. The purpose of this study was to promote the patient’s rights practice through efficient intervention at the clinic of physiotherapy، Faculty of Rehabilitation، Tabriz University of Medical Sciences. This study was an interventional study that was performed based on patients perspectives. The collected data were classified with 6MP method، matched with the Iranian patient''s rights، and then an education-based intervention undertaken to promote the practice of patient’s rights. The study results showed that after intervention، an increase was done in patient’s rights aspects and Education-based intervention plays an important role in practicing the patient’s rights.

Neuromobilization techniques have been recently put forward in physiotherapy of carpal tunnel syndrome. The aim of this study was to assess the effect of neuromobilization on different aspects of evaluation including subjective، physical، and electrophysiological findings in CTS. In this randomized clinical trial study، 20 patients with carpal tunnel syndrome (32 hands) were assigned into two groups; treatment and control group. In both groups، the patients received the physiotherapy modalities including the rest splint، TENS، and therapeutic ultrasound for 4 weeks. In addition to the physiotherapy modalities، the patients in treatment group received the neuromobilization techniques. The symptoms severity scale، visual analogue scale، functional status scale، Phalen''s sign، median nerve tension test، and median nerve sensory and motor distal latency were assessed. Data were analyzed by Kolmogrolf-Sminolf، Paired T and Independent T and Mc nemar tests. There was a significant improvement in symptoms severity scale، visual analogue scale، median nerve tension test، and Phalen''s sing in both groups (P<0. 05). However، the functional status scale (P<0. 001) and median nerve motor distal latency (P=0. 015) were significantly improved only in the treatment group who received the neuromobilization. There was no significant difference between two groups in any other parameters (P>0. 05)، except that the median nerve tension test (P<0. 001) and functional status scale (P=0. 004) was improved in the treatment group (P=0. 023). Physiotherapy modalities and neuromobilization itself have positive effects on hand symptoms and the finding of physical examination. Thus، we suggest adding the neuromobilization techniques into the physiotherapy modalities in patients with carpal tunnel syndrome.

Patient rights include care issues that patients expect to receive. Studies show that compliance of patient rights leads to improvement of therapeutic outcomes and clients’ satisfaction. The purpose of this study was to evaluate the patient rights’ compliance and improvement in physiotherapy clinic of Tabriz Rehabilitation Faculty in 1389-1390 by applying effective and efficient interventions. This is a descriptive-interventional study that was performed in 15 months by participation of 204 patients. Data were collected using a researcher-made questionnaire which its reliability and validity were assessed and approved. In pretest, the questionnaire included 7 questions in demographic factors and 38 questions in 11 aspects of service quality. In posttest, the number of aspects and questions were increased to 12 and 38, respectively. The collected data were analyzed using SPSS 16 software. According to the results of pretest data, aspects such as choosing provider, safety, prevention, dignity, autonomy and accessibility had non-acceptable service quality scores which were improved by applying effective and efficient interventions. Regarding the obtained results, patient rights could be improved by analyzing, prioritization and implementation of proper interventions. The acquired results from this study could be employed in same contexts to build a respectful environment in health care services.
