Arabic version of the Extended Nordic Musculoskeletal Questionnaire, cross-cultural adaptation and psychometric testing

BackgroundThe Extended Nordic Musculoskeletal Questionnaire (NMQ-E) had never been adapted into Arabic. We culturally adapted the NMQ-E to Arabic in five stages and investigated its psychometric properties.MethodsAfter translating and cross-culturally adapting the NMQ-E into Arabic, through forward translation, translation synthesis, backward translation, expert committee review, and pilot testing, the psychometric properties were investigated. The construct validity was assessed by having the participants completing the Arabic version of the NMQ-E with four Arabic scales that measured musculoskeletal pain in all regions covered in the NMQ-E. Participants’ baseline records were also used to evaluate internal consistency (Cronbach’s α). Seven days later, participants completed the Arabic NMQ-E again to evaluate its test–retest reliability employing intraclass correlation coefficient (ICC) and standard error of measurement (SEM) for the age questions, and Cohen’s kappa coefficient (κ), the proportion of observed agreement (Po), the proportion of positive agreement (Ppos), and the proportion of negative agreement (Pneg) for the dichotomous items.ResultsA total of 127 participants, 70 males and 57 females with mean age 32.5 ± 12.2 years, were included. Significant differences were found between participants with and without musculoskeletal pain in the corresponding scales, signifying the content validity of the questionnaire. Cronbach’s α for both the prevalence and consequences pain sections combined ranged from 0.30 to 1.00. The test–retest reliability of the age questions was excellent, with ICC values ranging between 0.995 and 1.00. The SEM was 0.77 for the neck region and 0 for the rest of the regions. The prevalence questions demonstrated almost perfect agreement, with κ values ranging between 0.82 and 1.00, the Po between 0.94 and 1.00, the Ppos between 0.80 and 1.00, and the Pneg between 0.93 and 1.00. The consequences of pain questions showed moderate-to-perfect agreement, with κ values ranging between 0.57 and 1.00, between 0.83 and 1.00 for the Po, between 0.50 and 1.00 for the Ppos, and between 0.86 and 1.00 for the Pneg.ConclusionsThe results suggest that the Arabic NMQ-E is a valid and reliable tool that can be used to screen Arab adults for the prevalence and consequences of musculoskeletal pain.

Prevalence and consequences of musculoskeletal pain in the upper and lower extremities: A cross-sectional analysis of patients with type 1 and type 2 diabetes in Denmark

AimsTo describe the one-week and 12-month prevalence of musculoskeletal pain in the upper and lower extremities and consequences in relation to care seeking, leisure time activity, and work life in patients with type 1 and 2 diabetes. MethodsA cross-sectional survey including adults diagnosed with type 1 and 2 diabetes from two Danish secondary care databases. Questions covered pain prevalence (shoulder, elbow, hand, hip, knee, ankle) and its consequences based on the Standardised Nordic Questionnaire. Data was presented using proportions (95 % confidence intervals). ResultsThe analysis included 3767 patients. The one-week prevalence was 9.3–30.8 % and 12-month prevalence 13.9–41.8 %, highest for shoulder pain (30.8–41.8 %). The prevalence was similar between type 1 and 2 diabetes for the upper extremity, but higher in type 2 for the lower extremity. Women had a higher pain prevalence for any joint for both diabetes types, while estimates did not vary between age groups (<60 or ≥60 years). More than half of the patients had reduced their activities at work or leisure time, and more than one-third had sought care during the past year because of pain. ConclusionsMusculoskeletal pain in the upper and lower extremities is common in patients with type 1 and 2 diabetes from Denmark, with considerable consequences for work and leisure activities.

Work-related musculoskeletal disorders among Pakistani construction workers: Prevalence, characteristics, and associated risk factors.

Worldwide, approximately 350 million people are currently employed in the construction industry. To determine the prevalence, pain characteristics, and associated risk factors for musculoskeletal disorders (MSDs) among construction workers in Pakistan. This study was a cross-sectional survey conducted from February to August 2019 among 666 construction workers. The data were collected using a questionnaire consisting of 4 sections: demographic information, a numerical pain intensity rating scale, a Nordic questionnaire to report prevalence, and pain characteristics. SPSS was used for data entry and analysis. The mean age of the construction workers was 34.49 years. Participants who reported pain were 397 out of 666 and 269 were those who reported no pain. The 12-month prevalence of pain among construction workers in more than one body area was 89% (n = 591) and the 7-day prevalence was 52% (n = 343); lower back pain was the most common type of pain with a 12-month prevalence of 27% (n = 180) and a 7-day prevalence of 17% (n = 112). Regarding the characteristics of the pain, 26% (173) of the workers suffered pain occasionally, 27% (180) participants had pain for≤2 hours per day, and 32.9% (219) had dull pain. Moreover, a significant relationship was found (p < 0.05) between MSDs and age, lifestyle, work experience, smoking habits, and absence from work. Musculoskeletal pain is highly prevalent, with lower back pain being the most commonly reported type. Absence from work and disability in performing normal daily activities have been reported as consequences of musculoskeletal pain. Moreover, this study underscores the importance of targeted preventive healthcare measures for construction workers.

Whose pain is it anyway? Comparability of pain reports from children and their parents.

BackgroundThere is a high demand for robust research into understanding the scope and consequences of musculoskeletal pain in children. An important part of this involves clarifying issues surrounding its measurement, not least differences in reporting from the children themselves and their parents. Therefore this study will assess the degree of agreement between parents’ report of their child’s pain and the child’s own assessment.MethodsData were collected in 2013 and 2014 as part of a larger cohort study investigating the health of Danish school children. Two study samples included 354 and 334 child–parent pairs who were independently asked whether the child had experienced musculoskeletal pain in the previous week. Children were between the ages of 10 and 14 years old. Parents provided answers via text message and children were questioned in person or via questionnaire at their school.ResultsPercentage agreement between parent and child assessment was around 50 % in Sample 1 and 68 % in Sample 2. The poor agreement was due to children reporting pain when their parent did not, the reverse very rarely occurred. Pain of greater intensity or longer duration resulted in better agreement between the child and parent. Child age and gender did not influence the likelihood of agreement.ConclusionChildren often experience pain that is not reported by their parents resulting in poor concordance between pain reports from the two sources. While it is not possible to say which is more valid we can conclude they are not interchangeable.

Musculoskeletal problems and quality of life of elementary school teachers

Purpose: To investigate prevalence and anatomical distribution of musculoskeletal pain (MSP) and its impact on quality of life (QoL) in elementary school teachers working in Muğla town center. Methods: Physical, sociodemographic and occupational characteristics of 104 teachers were recorded. Onset, prevalence and consequences of MSP (Extended Nordic Musculoskeletal Questionnaire) and QoL (Short Form-36 Health Survey) of teachers with (n = 37) and without (n = 67) MSP during the last 12 months were compared. Results: The prevalence of MSP was 77% for the lifelong period and 36% for the last 12 months. Physical and sociodemographic characteristics, daily employment period and length of standing and sitting were similar between groups (p > 0.05). The most common painful regions were the neck (39%) and the lower back (38%). MSP of these regions was the common reason for seeking healthcare, prevention from activities and taking sick leave. MSP had negative impact, especially on the physical components of QoL (p < 0.05). Conclusions: The results reveal high prevalence of MSP among teachers, as well as its negative impacts on QoL. Especially neck and lower back seem to be the most frequently affected regions of the body. These findings draw attention toward the need for developing strategies to prevent MSP among teachers.

Effect of workplace- versus home-based physical exercise on pain in healthcare workers: study protocol for a single blinded cluster randomized controlled trial

BackgroundThe prevalence and consequences of musculoskeletal pain is considerable among healthcare workers, allegedly due to high physical work demands of healthcare work. Previous investigations have shown promising results of physical exercise for relieving pain among different occupational groups, but the question remains whether such physical exercise should be performed at the workplace or conducted as home-based exercise. Performing physical exercise at the workplace together with colleagues may be more motivating for some employees and thus increase adherence. On the other hand, physical exercise performed during working hours at the workplace may be costly for the employers in terms of time spend. Thus, it seems relevant to compare the efficacy of workplace- versus home-based training on musculoskeletal pain. This study is intended to investigate the effect of workplace-based versus home-based physical exercise on musculoskeletal pain among healthcare workers.Methods/DesignThis study was designed as a cluster randomized controlled trial performed at 3 hospitals in Copenhagen, Denmark. Clusters are hospital departments and hospital units. Cluster randomization was chosen to increase adherence and avoid contamination between interventions. Two hundred healthcare workers from 18 departments located at three different hospitals is allocated to 10 weeks of 1) workplace based physical exercise performed during working hours (using kettlebells, elastic bands and exercise balls) for 5 × 10 minutes per week and up to 5 group-based coaching sessions, or 2) home based physical exercise performed during leisure time (using elastic bands and body weight exercises) for 5 × 10 minutes per week. Both intervention groups will also receive ergonomic instructions on patient handling and use of lifting aides etc. Inclusion criteria are female healthcare workers working at a hospital. Average pain intensity (VAS scale 0-10) of the back, neck and shoulder (primary outcome) and physical exertion during work, social capital and work ability (secondary outcomes) is assessed at baseline and 10-week follow-up. Further, postural balance and mechanical muscle function is assessed during clinical examination at baseline and follow-up.DiscussionThis cluster randomized trial will investigate the change in self-rated average pain intensity in the back, neck and shoulder after either 10 weeks of physical exercise at the workplace or at home.Trial registrationClinicalTrials.gov (NCT01921764).

Development and Test–Retest Reliability of an Extended Version of the Nordic Musculoskeletal Questionnaire (NMQ-E): A Screening Instrument for Musculoskeletal Pain

The Nordic Musculoskeletal Questionnaire (NMQ) quantifies musculoskeletal pain and activity prevention in 9 body regions. The purpose of this study was to develop an extended NMQ (NMQ-E) to collect greater information regarding musculoskeletal pain, examine test-retest reliability and the reproducibility of alternate administration methods. Reliability was examined using observed proportion of agreement for all (P(o)), positive (P(pos)) and negative (P(neg)) responses, kappa (kappa), proportion of maximum kappa achieved (kappa/kappa(max)), intra-class correlation coefficient (ICC) and standard error of measurement (SEM). The NMQ-E was self-administered by 59 Bachelor of Nursing students at a 24-h interval with mean P(o) = 0.88-0.98 and kappa/kappa(max) = 0.71-0.96 for 10 dichotomous questions and mean ICC((2,1)) = 0.97 and SEM = 1.05 years for the age at symptom onset question. The NMQ-E was completed via self and interview administration by 31 student nurses at a 0.97 +/- 1.14 day interval with mean P(o) = 0.92-0.98 and kappa/kappa(max) = 0.76-1.00 for binary questions and mean ICC((2,1)) = 0.90 and SEM = 1.51 years for age at symptom onset data. In both sub-studies, mean P(pos) was lower than mean P(neg) and low prevalence reduced kappa in many instances. The NMQ-E collects reliable information regarding the onset, prevalence, and consequences of musculoskeletal pain and can be administered by self-completion and personal interview. This study presents an NMQ-E that collects reliable information regarding the onset, prevalence, and consequences of musculoskeletal pain in 9 body regions. The NMQ-E can be utilized in descriptive studies or longitudinal studies of disease outcome and can be administered via self-completion and personal interview.

Pain catastrophizing and consequences of musculoskeletal pain: A prospective study in the Dutch community

By elaborating on previous prospective and cross-sectional research, the primary aim of this study was to examine in the general community whether pain catastrophizing predicts the development of chronic pain complaints and other consequences of pain. The following health index values were examined as consequences of pain: specialist consultation, use of pain medication, and absenteeism. It was also examined whether these relationships were moderated by the number of pain problems and by pain intensity. The results demonstrated a generally low level of catastrophizing and a small but significant effect of catastrophizing on the development of chronic pain complaints. With respect to the health index values, no significant effects of catastrophizing were found, nor were the relationships between catastrophizing and chronicity and the health index values moderated by the number of pain problems or by pain intensity. Perspective Because in the general community the level of catastrophizing is low, its role in the development of future pain problems is probably limited in this type of setting. More practically, the Pain Catastrophizing Scale, used to measure pain catastrophizing, is probably of limited use as a screening instrument in the general community. The disappointing results may indicate that, depending on the specific setting (eg, clinical, outpatient, or community) the role of pain catastrophizing is either more or less prominent.
