Quantitative Electroencephalography (QEEG) is a tool helping better understand the electrical activity of the brain and a non-invasive method to assess cortical activity. To date, the brain activity of patients with chronic patellofemoral pain (PFP) has not been investigated. The current study aimed to investigate the effect of PFP on higher levels of the central nervous system by assessing the correlation between QEEG and modified excursion balance test (mSEBT) in patients with PFP. Twenty-two patients with chronic PFP participated in this observational study. Their cortical electrical activity was recorded in a resting state with their eyes open, via a 32-channel QEEG. C3, C4, and Cz were considered as regions of interest. In addition to QEEG, the balance performance of the participants was evaluated via mSEBT. The obtained findings revealed a negative and moderate to high correlation between theta absolute power and posteromedial direction of mSEBT in C4 (P: 0.000, r: -0.68), Cz (P: 0.001, r: -0.66), and C3 (P 0.000, r: -0.70). Additionally, a significantly close correlation is between alpha absolute power in C3 (P: 0.001, r: -0.70), C4 (P: 0.000, r: -0.71), and Cz (P: 0.000, r: -0.74) and the posteromedial direction of mSEBT. No significant correlations were between the other two directions of mSEBT, alpha, and theta.  According to our results, balance impairment in patients with chronic PFP correlated with their QEEG neurodynamics. Moreover, our findings demonstrated the efficiency of QEEG as a neuromodulation method for patients with PFP.

Musculoskeletal pain and burnout can influence the quality of services provided by librarians working in libraries; therefore, the present study has been designed to investigate the prevalence of musculoskeletal pain as well as the existence of burnout among librarians working in libraries affiliated with Shiraz University of Medical Sciences.

This is a descriptive cross-sectional study conducted by taking a census of librarians working in libraries affiliated with Shiraz University of Medical Sciences. The prevalence of musculoskeletal pain was assessed using the standard Nordic questionnaire, and the pain intensity was measured based on the numeric pain rating scale. The standard Maslach and Jackson questionnaire, with a reliability coefficient of 0.78, was used to measure burnout.

According to the findings, the most common musculoskeletal pain experienced by the librarians was a pain in the spinal region, particularly in the low back, and after that, the pain in the upper limb was most frequent. In terms of burnout, librarians experienced low levels of emotional exhaustion and depersonalization, and moderate levels of personal accomplishment.

All librarians reported at least one musculoskeletal pain. Low back pain is frequent among librarians. These individuals suffer from burnout.

Regular physical activity is effective in the treatment of low back pain. However, adherence to these exercises is difficult. Nowadays, the health care industry is using various forms of ICT to provide services to patients. Therefore, the aim of this study was to survey the willingness and use of information and communication technologies among people with low back pain.

This is an analytical study conducted in 2017. In this study, 200 samples low back pain were collected by use of convenience sampling method. The data collection tool was a checklist.

Nighty-nine percent of the participants used mobile phones based on Android; in addition, 51% of people stated that they were familiar with the Internet. Also, people with the mean age and standard deviation of 37 ± 9 were willing to use ICT tools more compared with people with the mean age and standard deviation of 45±13; in addition, they had a high willingness to use ICT tools and low willingness to use traditional tools (p<0.001).

In general, the results showed that a large number of people with low back pain were willing to use ICT tools to receive care services (like exercise therapy). The majority of people with low back pain used social networks and they had smart phones based on the Android whose services were used widely. So the technologies such as smartphones, laptops, social networks and internet services could be used for e-learning.

The Patient Assessment of Constipation Quality of Life (PAC-QOL) questionnaire is the most validated and the most specific tool for measuring the quality of life of patients with constipation. Over 120 million people live in countries whose official language is Persian. There is no reported Persian version of the PAC-QOL questionnaire yet. The aim of this study was to translate and culturally adapt the PAC-QOL questionnaire and to assess its reliability and validity among Persian patients with chronic constipation.
Following the translation and cultural adaptation of the PAC-QOL questionnaire to Persian, 100 patients (mean±SD age=40.51±13.67) with constipation were recruited for validity measurement and 20 patients were re-examined for reliability. Content validity was assessed based on the opinions of an expert committee and the floor/ceiling effect. Construct validity was evaluated according to the hypothesis test. The SF-36 questionnaire was used for concurrent criterion validity, intra-class correlation coefficient for reliability, and Cronbach’s alpha for internal consistency.
The content validity of the PAC-QOL questionnaire was proven, and there was no floor/ceiling effect. Construct validity also was confirmed based on the hypothesis test. The overall Cronbach’s alpha of the PAC-QOL questionnaire was 0.92 (range=0.72–0.92), and the overall intra-class correlation coefficient of the questionnaire was 0.88 (range=0.69–0.87). The correlation between the SF-36 and PAC-QOL questionnaires was moderate.
The Persian version of the PAC-QOL questionnaire demonstrated good validity and reliability properties in chronic constipation. Accordingly, Persian researchers and clinicians can benefit from this questionnaire in further research and assessment of treatment outcomes.

The aim of this study is evaluation of the validity and reliability of the Persian version of Knee Injury and Osteoarthritis Outcome Score (KOOS) in patients with isolated meniscus injury.
One hundred people with isolated meniscal injury (29 females and 71 males with a mean age ± standard deviation [SD] = 32.37 ± 9.97 years) and ?fty normal people with no knee problems (34 females and 16 males with a mean age ± SD = 28.42 ± 8.84 years) participated in this study. In patients, the duration of meniscus injury ranged from 1 month to 4 years. For evaluation of discriminate validity, we compared scores of KOOS questionnaire between patients and healthy people, and for concurrent validity, in addition to ?lling KOOS questionnaire, patients completed Short Form (SF-36) questionnaire, test–retest reliability with intraclass correlation coe?cient) ICC), and internal consistency with Cronbach’s alpha was calculated.
Mean scores of patients (49.51 ± 17.13) and healthy people (86.01 ± 13.44) were di?erent signi?cantly (P The Iranian version of KOOS is a reliable and valid tool for patients with isolated meniscus injury, so the clinicians and investigators may use this questionnaire in clinical settings and their researches.
