The epidemiology of neck and low back pain in Iran: a national and sub-national analysis from 1990 to 2019.

Background: Neck pain (NP) is a condition influenced by multiple factors. It places a significant burden on individuals suffering from NP and on social and economic systems. On a global scale, low back pain (LBP) stands out as a significant contributor to years lost to disability, and this burden is on the rise due to population growth and aging. Methods: The Global Burden of Disease database was used to collect data on the prevalence, incidence, and years lived with disability (YLD) of NP and LBP between 1990 and 2019. Various factors, including age group, gender, Iran, and its 31 provinces, were used to classify the data. Results: Iran accounted for 0.86 million incident cases of NP in 2019, with age-standardized incident rate per 100 000 population of 934.1. Tehran has the maximum age-standardized prevalence, incidence, and YLD. Iran accounted for the age-standardized incidence rate for LBP per 100 000 population of 3492.9, and it reduced to -8.35% from 1990. Mazandaran exhibits the highest levels of prevalence, incidence, and YLD for LBP in 2019. In Iran, the point prevalence of NP in 2019 was higher in females and increased with age up to 50-54 years for females and 70-74 years for males. However, there is only a slight difference between females and males in Iran regarding LBP prevalence. Conclusions: In this study, the authors report the prevalence, incidence, YLD, and age-standardized rates for NP and LBP in the world's general population and Iran's population based on its sub-nations in 1990 and 2019.

Ultrasound-Guided Injection of Dextrose Versus Corticosteroid in Chronic Plantar Fasciitis Management: A Randomized, Double-Blind Clinical Trial.

DESIGN: Chronic plantar fasciitis (PF) is a common cause of chronic heel pain, with different conventional treatment options. In this randomized clinical trial, the effect of ultrasound-guided injection of dextrose versus corticosteroid in chronic PF was evaluated and compared. METHODS: A total of 44 patients suffering from chronic PF who visited the physical medicine and rehabilitation clinic were enrolled in the study. Two table-randomized groups were formed. They received an ultrasonography-guided, single injection of either 40 mg methylprednisolone or 20% dextrose. Numeric Rating Scale (NRS), Foot and Ankle Ability Measure questionnaire with 2 subscales, Activities of Daily Living (FAAM-A) and Sports (FAAM-S), along with ultrasonographic parameters were evaluated before and at 2 and 12 weeks after the injection. Results. A total of 40 participants completed the study. Both interventions significantly improved pain and function at 2 and 12 weeks postinjection. After 2 weeks, compared with the dextrose prolotherapy, the corticosteroid group had significantly lower daytime and morning NRS scores (2.55 vs 4.1, P = .012, and 2.75 vs 4.65, P = .004), higher FAAM-S (66.84 vs 54.19; P = .047), and lower plantar fascia thickness at insertion and 1 cm distal to the insertion zone (3.89 vs 4.29 mm, P = .004, and 3.13 vs 3.48 mm, P = .002), whereas FAAM-A was similar in both groups (P = .219). After 12 weeks, all study variables were statistically similar between corticosteroid and dextrose prolotherapy groups. No injection-related side effects were recorded in either group. CONCLUSION: Both methods are effective. Compared with dextrose prolotherapy, our results show that corticosteroid injection may have superior therapeutic effects early after injection, accompanied by a similar outcome at 12 weeks postinjection. LEVELS OF EVIDENCE: Level II.

The incidence and characteristics of chronic pain and fatigue after 12 months later admitting with COVID-19; The Post- COVID 19 syndrome.

INTRODUCTION: This study aimed to evaluate chronic pain and fatigue in patients 12 months after hospitalization for Covid-19. METHODS: We studied the COVID-19 patients discharged from Hospital, March 10 and April 20, 2020. RESULTS: A total of 157 patients were included in this study. Forty-three patients (27.4%) complained of chronic fatigue and muscle weakness in the last six months. The visual analog fatigue scale (VAFS) score of 3.84 ± 1.48 was obtained. Forty patients (25.5%) were suspected of Chronic Fatigue Syndrome (CFS).Twenty-four patients (15.3%) had severe chronic pain or exacerbation of previous chronic pain, most of which were reported in the lower back (70.8%) and lower extremities (66.7%). Pain intensity had a mean score of 2.33 ± 0.87 and was mainly described as "muscle cramps," "persistent dull pain," and "boring and numbing." In women, chronic pain and fatigue, extended hospital stays, ICU admission, and depressed mood were common than in men.For these pain and fatigue, 37% used nonsteroidal anti-inflammatory drugs, and 16.3% used antidepressants. Only one person had applied for physiotherapy, and none of the patients had received psychotherapy. CONCLUSION: Fatigue and chronic pain in patients recovering from COVID-19 are common complications, even after 12 months of illness.

Comparison of Extracorporeal Shockwave Therapy and Blind Steroid Injection in Patients With Coccydynia: A Randomized Clinical Trial.

OBJECTIVE: Extracorporeal shockwave therapy (ESWT) emerged recently for the treatment of musculoskeletal conditions owing to its regenerative and anti-inflammatory effects. In this study, the aim was to compare the efficacies of ESWT and steroid injection in patients with coccydynia. DESIGN: Thirty-four patients with coccydynia were randomized into two groups. In the ESWT group, patients received radial shockwave for three weekly sessions. The second treatment group received an injection of steroid in the tip of the coccyx or sacrococcygeal junction. Outcome measures were visual analog scale, Short-Form Health Survey, and Dallas Pain Questionnaire. Visual analog scale was measured at baseline and 1 wk, 1 mo, 2 mos, and 6 mos after the intervention. Short-Form Health Survey and Dallas Pain Questionnaire were assessed before and 1 mo after treatment. RESULTS: The visual analog scale score was significantly decreased in all follow-ups in both groups. There was also a significant decrease between 1 wk and three other posttreatment visits in the ESWT treatment group. Time and group interaction effect was significant on the visual analog scale (F2.64, 84.63 = 2.95, P = 0.043), in favor of ESWT. Concerning the Short-Form Health Survey and Dallas Pain Questionnaire, only some dimensions improved. CONCLUSIONS: ESWT is an effective intervention in patients with coccydynia and had more long-lasting efficacy than steroid in terms of pain relief over 6 mos of observation.

Continuous post-disaster physical rehabilitation: a qualitative study on barriers and opportunities in Iran.

BACKGROUND: Internationally, inclusion of physical rehabilitation services during early disaster response is relatively new. The aim of the study was to gain an understanding of disaster relief physical rehabilitation in Iran. METHODS: A qualitative study design was employed and sixteen semi-structured interviews were conducted for data collection. Content analysis was used for data analysis. The participants in this study were purposively selected among people who experienced the Bam (2003) and Varzaghan (2012) earthquakes. RESULTS: Three main themes were explored including: indispensable intervention, barriers to continuous intervention and opportunities for intervention. Almost all participants reiterated the importance of effective physical rehabilitation services during disasters. Some participants mentioned significant barriers for delivering such services in the context of Iran. The lack of an effective responsible body, weak disaster-related competencies and under-prioritization by government were among other barriers. On a more positive note, some interviewees talked about national programs that could facilitate service delivery. CONCLUSIONS: Providing disaster relief physical rehabilitation has faced many barriers in Iran. However, there are some facilitators in the country that could help provide these services. Finally, the feasibility of post-disaster physical rehabilitation services delivery completely depends on the current national rehabilitation system.

The Effect of Repetitive Transcranial Magnetic Stimulation on Postural Stability After Acute Stroke: A Clinical Trial.

INTRODUCTION: Balance impairment is a common problem and a major cause of motor disability after stroke. Therefore, this study aimed to investigate whether low-frequency repetitive Transcranial Magnetic Stimulation (rTMS) improves the postural balance problems in stroke patients. METHODS: This randomized double blind clinical trial with 12 weeks follow-up was conducted on stroke patients. Treatment was carried with 1 Hz rTMS in contralateral brain hemisphere over the primary motor area for 20 minutes (1200 pulses) for 5 consecutive days. Static postural stability, Medical Research Council (MRC), Berg Balance Scale (BBS), and Fugl-Meyer assessments were evaluated immediately, 3 weeks and 12 weeks after intervention. RESULTS: A total of 26 patients were enrolled (age range=53 to 79 years; 61.5% were male) in this study. Administering rTMS produced a significant recovery based on BBS (df=86, 7; F=7.4; P=0.01), Fugl-Meyer Scale (df=86, 7; F=8.7; P<0.001), MRC score (df=87, 7; F=2.9; P=0.01), and static postural stability (df=87, 7; F=9.8; P<0.001) during the 12 weeks follow-up. CONCLUSION: According to the findings, rTMS as an adjuvant therapy may improve the static postural stability, falling risk, coordination, motor recovery, and muscle strength in patients with stroke.

Professionalism in residents of physical medicine and rehabilitation in Iran.

Professionalism is the foundation of trust on which the doctor-patient relationship is built. This study was performed to measure professionalism in Iranian physical medicine and rehabilitation residents as a baseline assessment tool for future studies. This was a descriptive study. The Persian version of the American Board of Internal Medicine (ABIM) questionnaire was distributed among all the second and third-year residents of the medical state universities of Iran (n=43). Data were summarized as mean (SD), and independent samples t-test was used for comparison of means between genders, and also between the second and third-year residents. Forty questionnaires were analyzed. The mean (± SD) age of respondents was 29.95 (± 2.37) years. The mean score (SD) for the overall score was 115.15 (± 17.36) out of 150, and the mean score (± SD) for all items was 7.67 (± 1.15) out of 10. The respondents averaged 5.88 (± 1.69) for items forming the 'excellence' factor, 7.98 (± 1.48) for items in 'altruism/respect' and 8.92 (± 1.26) for items in the 'honor/integrity' subscale. These data may serve as a baseline for future research in this field. The lowest score pertained to excellence, which needs more focus in future studies.

The effects of a new designed forearm orthosis in treatment of lateral epicondylitis.

PURPOSE: This paper reports on the design and testing of a new designed forearm orthosis and explores its efficacious in comparison to the standard counterforce orthosis in patients with lateral epicondylitis. METHOD: Twenty-four patients were enrolled in this assessor-blinded clinical trial and randomly assigned to two parallel treatment groups. The measures of pain and function, the pain threshold and grip strength were compared using patient rated tennis elbow evaluation (PRTEE) form, algometer and dynamometer respectively at baseline and 4 weeks after treatment. Paired and independent t-test statistical methods recruited for within and between groups comparisons respectively. RESULTS: The both orthoses, counterforce and new-designed, significantly relieved pain, and improved function, pain threshold and grip strength of all patients after 4 weeks application. The new-designed orthosis seemed to be more effective than the counterforce orthosis in pain relief, but there was not any significant difference in efficacious of two types of orthoses regarding function. CONCLUSIONS: The new-designed orthosis can significantly relieve pain, improve function, increase pain threshold and grip strength after application. This orthosis seemed to be more effective than counterforce orthosis in relieving pain and increasing the pain threshold probably due to the limitation of forearm supination.

Results from the translation and adaptation of the Iranian Short-Form McGill Pain Questionnaire (I-SF-MPQ): preliminary evidence of its reliability, construct validity and sensitivity in an Iranian pain population.

BACKGROUND: The Short Form McGill Pain Questionnaire (SF-MPQ) is one of the most widely used instruments to assess pain. The aim of this study was to translate and culturally adapt the questionnaire for Farsi (the official language of Iran) speakers in order to test its reliability and sensitivity. METHODS: We followed Guillemin's guidelines for cross-cultural adaption of health-related measures, which include forward-backward translations, expert committee meetings, and face validity testing in a pilot group. Subsequently, the questionnaire was administered to a sample of 100 diverse chronic pain patients attending a tertiary pain and rehabilitation clinic. In order to evaluate test-retest reliability, patients completed the questionnaire in the morning and early evening of their first visit. Finally, patients were asked to complete the questionnaire for the third time after completing a standardized treatment protocol three weeks later. Intraclass correlation coefficient (ICC) was used to evaluate reliability. We used principle component analysis to assess construct validity. RESULTS: Ninety-two subjects completed the questionnaire both in the morning and in the evening of the first visit (test-retest reliability), and after three weeks (sensitivity to change). Eight patients who did not finish treatment protocol were excluded from the study. Internal consistency was found by Cronbach's alpha to be 0.951, 0.832 and 0.840 for sensory, affective and total scores respectively. ICC resulted in 0.906 for sensory, 0.712 for affective and 0.912 for total pain score. Item to subscale score correlations supported the convergent validity of each item to its hypothesized subscale. Correlations were observed to range from r2 = 0.202 to r2 = 0.739. Sensitivity or responsiveness was evaluated by pair t-test, which exhibited a significant difference between pre- and post-treatment scores (p < 0.001). CONCLUSION: The results of this study indicate that the Iranian version of the SF-MPQ is a reliable questionnaire and responsive to changes in the subscale and total pain scores in Persian chronic pain patients over time.
