BACKGROUND: Conservative treatments such as physical therapies are usually the most indicated for the management of musculoskeletal pain; therefore, a detailed description of interventions enables the reproducibility of interventions in clinical practice and future research. The objective of this study is to evaluate the description of physical interventions for musculoskeletal pain in children and adolescents.
METHODS: We considered randomized controlled trials that included children and adolescents between 4 and 19 years old with acute or chronic/persistent musculoskeletal pain. We included physical therapies related to all types of physical modalities aimed at reducing the intensity of pain or disability in children and adolescents with musculoskeletal pain. The description of interventions was assessed using the Template for Intervention Description and Replication (TIDieR) checklist. We performed electronic searches in the following databases: CENTRAL, MEDLINE, EMBASE, CINAHL, PsyINFO and PEDro up to April 2024. The description of physical interventions was presented using frequencies, percentages and 95% confidence intervals (CIs) of the TIDieR checklist items described in each study. We also calculated the total TIDieR score for each study and presented these data as mean and standard deviation.
RESULTS: We included 17 randomized controlled trials. The description measured through the TIDieR checklist scored an average of 11 (5.2) points out of 24. The item of the TIDieR that was most described was item 1 (brief name) and most absent was item 10 (modifications).
CONCLUSIONS: The descriptions of physical interventions for the treatment of musculoskeletal pain in children and adolescents are partially described, indicating the need for strategies to improve the quality of description to enable true clinical reproducibility.

Objective: To explore the risk factors of neck work-related musculoskeletal disorders (WMSDs) among automobile manufacturing enterprise workers, and construct the risk prediction model. Methods: In May 2022, a cluster convenience sampling method was used to selet all front-line workers from an automobile manufacturing factory in Xiangyang City as the research objects. And a questionnaire survey was conducted using the modified Musculoskeletal Disorders Questionnaire to analyze the occurrence and exposure to risk factors of neck WMSDs. Logistic regression was used to analyze the influencing factors of workers\' neck WMSDs symptoms, and Nomogram column charts was used to construct the risk prediction model. The accuracy of the model was evaluated by the receiver operating characteristic (ROC) curve, the Bootstrap resampling method was used to verify the model, Hosmer-Lemeshow goodness of fit test was used to evaluate the model, and the Calibration curve was drawn. Results: A total of 1783 workers were surveyed, and the incidence of neck WMSDs symptoms was 24.8% (442/1783). Univariate logistic regression showed that age, female, smoking, working in uncomfortable postures, repetitive head movement, feeling constantly stressed at work, and completing conflicting tasks in work could increase the risk of neck WMSDs symptoms in automobile manufacturing enterprise workers (OR=1.37, 95%CI: 1.16-1.62; OR=2.85, 95%CI: 1.56-5.20; OR=1.50, 95%CI: 1.18-1.91; OR=1.18, 95%CI: 1.02-1.37; OR=1.34, 95%CI: 1.04-1.72; OR=1.62, 95%CI: 1.21-2.17; OR=1.48, 95%CI: 1.13-1.92; P<0.05). While adequate rest time could reduce the risk of neck WMSDs symptoms (OR=0.56, 95%CI: 0.52-0.86, P<0.05). The risk prediction model of neck WMSDs of workers in automobile manutacturing factory had good prediction efficiency, and the area under the ROC curve was 0.72 (95%CI: 0.70-0.75, P<0.001) . Conclusion: The occurrence of neck WMSDs symptoms of workers in automobile manufacturing factory is relatively high. The risk prediction model constructed in this study can play a certain auxiliary role in predicting neck WMSDs symptoms of workers in automobile manufacturing enterprise workers.
目的： 探讨汽车制造业工人颈部工作相关肌肉骨骼疾患（WMSDs）的影响因素，并构建风险预测模型。 方法： 于2022年5月，采用方便抽样法，选取襄阳市1家汽车制造厂所有一线工人作为研究对象，采用改良《肌肉骨骼疾患调查问卷》调查其颈部WMSDs症状发生情况及危险因素暴露情况，采用logistic回归分析工人颈部WMSDs症状发生的影响因素，用Nomogram列线图构建风险预测模型。通过受试者工作特征（ROC）曲线评价模型准确性，运用Bootstrap重抽样的方法进行模型验证，Hosmer-Lemeshow拟合优度检验评价模型，绘制校准曲线（Calibration curve）。 结果： 共调查1 783名工人，颈部WMSDs症状发生率为24.8%（442/1 783）。多因素logistic回归分析显示，年龄、女性、吸烟、以不舒服姿势工作、头部重复动作、总是感到工作压力大、完成有矛盾的工作会增加汽车制造业工人颈部WMSDs症状的发生风险（OR=1.37，95%CI：1.16~1.62；OR=2.85，95%CI：1.56~5.20；OR=1.50，95%CI：1.18~1.91；OR=1.18，95%CI：1.02~1.37；OR=1.34，95%CI：1.04~1.72；OR=1.62，95%CI：1.21~2.17；OR=1.48，95%CI：1.13~1.92；P<0.05），而休息时间充足会降低颈部WMSDs症状的发生风险（OR=0.56，95%CI：0.52~0.86，P<0.05）。该汽车制造厂工人颈部WMSDs风险预测模型具有较好的预测效能，ROC曲线下面积（AUC）为0.72（95%CI：0.70~0.75，P<0.001）。 结论： 该汽车制造厂工人颈部WMSDs症状发生率较高，本研究构建的风险预测模型可以对汽车制造业工人颈部WMSDs症状发生起到一定的辅助预测作用。.

OBJECTIVE: To determine the prevalence of spinal segmental sensitization (SSS) syndrome, a regional pain disorder, among patients visiting physical medicine and rehabilitation centers (PM&RCs) for chronic musculoskeletal pain (CMSP).
METHODS: An observational descriptive cross-sectional study conducted from March to July 2023.
METHODS: Seven PM&RCs from five cities, representing three care systems: social security (SS), Ministry of Health (MH), and private practice (PP).
METHODS: All patients, regardless of age, attending a physiatry consultation for CMSP for the first time and who provided informed consent to participate were included. Non-probabilistic sampling was employed.
METHODS: Not applicable.
METHODS: We estimated the overall prevalence of SSS syndrome as a percentage among patients with CMSP, stratified by healthcare institution, sex, age, and occupation type. We also recorded the spinal segments involved and any concomitant painful disorders (CPDs). SSS syndrome was diagnosed using standardized criteria.
RESULTS: Of the eligible participants, 319 with CMSP were enrolled; 73.4% were female, and the median age of participants was 56.9 (range: 13-89) years. The overall prevalence of SSS syndrome was 53.3%. Of these, 69.1%, 42.2%, and 13.8% were in the SS, MH, and PP systems, respectively. The most affected were female participants (56.4%), those aged 50-64 years (60.4%), and those with active jobs (58.8%). Most commonly, the lumbosacral and lumbar segments were affected, followed by the lower and middle cervical levels. Spine pathologies were the most common CPDs.
CONCLUSIONS: The prevalence of SSS syndrome was high among patients who visited PM&RCs for CMSP and varied according to the care system. Further research on SSS syndrome is warranted to relieve the burden it poses on patients with CMSP and ensure proper diagnosis in clinical practice.

Background: Musculoskeletal pain is one of the reasons for a musician\'s inability to play an instrument. An assessment of the localization, intensity, and interference of those complaints is important among musicians because of the risk of occupational disease. Assessment by validated tools is especially important and serves as an indicator to take up proper preventive or treatment actions. The aim of the study was to assess the prevalence of playing-related musculoskeletal disorders (PRMDs) and the relationships with PRMDs\' impact on playing musical instruments among Polish professional orchestra musicians. Methods: The study was conducted on a group of professional orchestra musicians (age 37.19 ± 9.62 years), 99 (55%) women and 83 (45%) men. Work experience in professional orchestra was 18.3 ± 9.83 years and the reported years of playing musical instrument were 31.4 ± 9.50. The study used the online version of a musician-dedicated questionnaire, Musculoskeletal Pain Intensity and Interference Questionnaire for Musicians of the Polish Population (MPIIQM-P). Results: In the study group, 89.9% of women and 83.1% of men had experienced playing-related pain in their lifetime. The most intense pain among the group with current playing-related musculoskeletal complaints (n = 85) was located in the neck area for 19 (22.4%). Conclusions: The results of the study indicate a high prevalence of playing-related musculoskeletal problems among professional musicians.

OBJECTIVE: Prolonged sitting is associated with an increased risk of musculoskeletal pain, especially in nightshift workers. However, research investigating effects of breaking up sitting on musculoskeletal pain during nightshifts is lacking. This study evaluated effects of prolonged sitting or breaking up sitting with short bouts of light-intensity physical activity on pain in healthy adults during simulated nightshifts.
METHODS: An in-laboratory randomised controlled trial was undertaken with 52 healthy adults completing five simulated nightshifts. Participants were randomised to prolonged sitting (Sit9; n = 26) or breaking up prolonged sitting (Break9; n = 26). Break9 group completed 3-min walking every 30 min during nightshifts, while Sit9 group remained seated. Musculoskeletal pain intensity and sensory/affective pain experiences were assessed. Linear mixed models examined pain within nights (pre-to post-shift) and across nights (pre-shift-night-1 to pre-shift-night-5).
RESULTS: Musculoskeletal pain intensity increased within nights for both Sit9 (mean change [95%CI] points: 0.14 [0.05, 0.24]) and Break9 (0.09 [0.001, 0.19], but not across nights (Sit9: -0.13 [-0.33, 0.08]; Break9: 0.07 [-0.14, 0.29]). Sensory-pain experience improved across nights for Sit9 (-3.08 [-4.72, -1.45]), but not within nights (0.77 [-0.004, 1.55]). There was no change in affective-pain experience in either group. Between-group difference was observed favouring Sit9 for improving sensory-pain across nights (β: 3.71 [1.42, 5.99]). No other between-group difference was observed.
CONCLUSIONS: Both prolonged sitting and breaking up sitting were associated with a within-night increase in musculoskeletal pain intensity. Compared to prolonged sitting, breaking up sitting did not induce benefits on pain in healthy adults working simulated nightshifts.

BACKGROUND: The purpose of this study was to ascertain whether there is a difference in musculoskeletal pain between those who are addicted to mobile games and those who are not, to ascertain the association between mobile game addiction and socio-demographic variables, and to ascertain the pain predictor for mobile game addiction on different musculoskeletal regions.
METHODS: There were 840 students in all, both males and females, in this cross-sectional survey from three distinct Bangladeshi institutions. The Nordic Musculoskeletal Discomfort Questionnaire, the Gaming Addiction Scale, and the demographic data form were distributed to the participants. The data were analyzed using the Chi-square test and descriptive statistics. Binary logistic regression was used to find the predicted risk factor for mobile gaming addiction.
RESULTS: Musculoskeletal pain affects 52.1% of participants in some part of the body. Males have a 2.01-fold higher likelihood of developing gaming addiction compared to females. Those who are addicted to mobile games experience a higher occurrence of pain in the neck, upper back, elbows, and wrist and hands with a odds ratio of (OR 2.84, 95% CI: 1.49-5.36; p = 0.016), (OR 3.75, 95% CI 1.97-7.12; p = <0.001), (OR 3.38, 95% CI 1.34-8.50; p = 0.010), and (OR 2.14, 95% CI 1.00-4.57; p = 0.049) respectively.
CONCLUSIONS: These results demonstrate that mobile gaming addiction raises students\' risk of musculoskeletal discomfort. Two-three times higher risk of developing pain in the neck, upper back, elbows, and wrist and hands among mobile game addicts.

BACKGROUND: Grip strength is an important indicator of muscle strength. Nursing job demands physical power, which is related to their muscle strength. However, studies on nurses\' grip strength remains lacking.
OBJECTIVE: This study aims to examine the differences in grip strength between staff nurses and nursing students and to identify factors associated with grip strength in nursing sample.
METHODS: This study was designed as descriptive and analytical. Data collected from nursing students and staff nurses in Turkiye, from May 1 to September 30, 2022. A total of 200 staff nurses and 200 nursing students participated. Data tool included a participant information form, the Perceived Stress Scale-4 (PSS-4), and the Nordic Musculoskeletal Questionnaire (NMQ). Moreover, researchers assessed the anthropometric measurements using the same scale and grip strength using a digital hand dynamometer.
RESULTS: There was no significant difference in grip strength of staff and student nurses. 48.8% of participants met or exceeded Turkish normative values. 79.5% of staff nurses and 66.0% of nursing students reported musculoskeletal issues in the last 12 months. Height, waist-to-hip ratio, and neck circumference was found to be significant predictors of grip strength, explaining 57% of the variance.
CONCLUSIONS: Grip strength was similar between staff nurses and nursing students, despite differences in age, BMI, and musculoskeletal issues. Height, waist-to-hip ratio, and neck circumference are key predictors of grip strength in this Turkish nursing sample. Understanding the factors influencing grip strength can help in designing targeted interventions to maintain and improve muscle strength in nursing professionals.

OBJECTIVE: To evaluate the effect of a workplace injury prevention and wellness program compared to no intervention (control) on musicians\' playing-related musculoskeletal pain intensity. The hypothesis was that musicians who completed the program would have a greater reduction in pain intensity than the control group. DESIGN: Pragmatic parallel randomized controlled trial. METHODS: Sixty-five orchestra musicians were recruited and completed patient-reported outcome measures (primary outcome: pain intensity over 11 months, using the Musculoskeletal Pain Intensity and Interference Questionnaire for Musicians; range: 0-40; lower is better) at baseline, 14 weeks (T1), and 11 months (T2). Following baseline assessment, participants were randomly assigned to the intervention (n = 33) or control (n = 32) groups, stratified by instrument and pain prevalence. The intervention group received a 14-week injury prevention and wellness program including education and exercise; the control group received no intervention. RESULTS: Pain intensity means (standard deviation) were 7.8 (6.2), 8.0 (7.5), and 8.6 (5.7) in the control group, and 9.0 (6.6), 5.0 (4.2), and 6.7 (6.6) in the intervention group at T0, T1, and T2, respectively. Using intention-to-treat analyses (3 dropouts, n = 65 analyzed), between-group differences in pain intensity (95% confidence interval) were T1-T0: -4.2 (-7.5, -0.9); T2-T0: -3.7 (-7.1, -0.3), type III (overall) P = .03, favoring the intervention group. No adverse events were reported. CONCLUSION: A workplace injury prevention and wellness program may have a clinically meaningful effect on reducing orchestra musicians\' pain intensity.

Subjective pain intensity can be measured using instruments like the Faces Pain Scale-Revised (FPS-R), Verbal Rating Scale (VRS), Numerical Pain Rating Scale (NPRS), and Visual Analogue Scale (VAS). However, information on physiotherapists\' and patients\' knowledge and preference for these tools is scarce.
We investigated the knowledge and preference of physiotherapists and participants with musculoskeletal pain (MP) regarding the pain intensity measurement scales.
This cross-sectional study consisted of physiotherapists and participants with MP. Physiotherapists were recruited via social media for an online open survey, gathering sociodemographic, professional data, and their knowledge and preferences for pain intensity scales. Participants over 18 with MP, participated in interviews focusing on their familiarity and preferences for pain intensity scales. Data was analyzed descriptively, and Chi-squared test evaluated scale preferences.
We included 352 physiotherapists (mean experience = 10.5 years) and 94 participants with MP. Of the physiotherapists, 94.3% were familiar with pain scales, but 30.4% struggled to differentiate them. The NPRS was the most used (56.3%) and preferred scale (52.4%). Among participants with MP, unfamiliarity was noted with all scales. After instruction, 46% preferred FPS-R, with preference varying by income and education levels (p < 0.001).
We found a knowledge gap among physiotherapists in identifying pain intensity scales, with a preference for the NPRS among those familiar with the scales. Participants with MP had limited familiarity with these scales. After instructions, these participants preferred the FPS-R, particularly those with lower income and education levels.

OBJECTIVE: To evaluate the patient-reported expectations regarding cannabis for pain following musculoskeletal (MSK) trauma and patients\' perceptions and attitudes regarding its use.
METHODS:
METHODS: A cross-sectional retrospective survey-based study.
METHODS: Three orthopaedic clinics in Ontario (Level-1 trauma center, Level-2 trauma center, rehabilitation clinic).
UNASSIGNED: Adult patients presenting to the clinics from January 24, 2018, to March 7, 2018, with traumatic MSK injuries (fractures/dislocations and muscle/tendon/ligament injury) were administered an anonymous questionnaire on cannabis for MSK pain.
UNASSIGNED: Primary outcome measure was the patients\' perceived effect of cannabis on MSK pain, reported on a continuous pain scale (0%-100%, 0 being no pain, and 100 unbearable pain). Secondary outcomes included preferences, such as administration route, distribution method, timing, and barriers (lack of knowledge, concerns for side effects/addiction, moral/religious opposition, etc.) regarding cannabis use.
RESULTS: In total, 440 patients were included in this study, 217 (49.3%) of whom were female and 222 (50.5%) were male, with a mean age of 45.6 years (range 18-92 years, standard deviations 15.6). Patients estimated that cannabis could treat 56.5% (95% CI 54.0%-59.0%) of their pain and replace 46.2% (95% CI 42.8%-49.6%) of their current analgesics. Nearly one-third (131/430, 30.5%) reported that they had used medical cannabis and more than one-quarter (123/430, 28.6%) used it in the previous year. Most felt that cannabis may be beneficial to treat pain (304/334, 91.0%) and reduce opioid use (293/331, 88.5%). Not considering using cannabis for their injury (132/350, 37.7%) was the most common reason for not discussing cannabis with physicians. Higher reported pain severity (β = 0.2/point, 95% CI 0.1-0.3, P = 0.005) and previous medical cannabis use were associated with higher perceived pain reduction (β = 11.1, 95% CI 5.4-16.8, P < 0.001).
CONCLUSIONS: One in 3 orthopaedic trauma patients used medical cannabis. Patients considered cannabis could potentially be an effective option for managing traumatic MSK pain and believed that cannabis could reduce opioid usage following acute musculoskeletal trauma. These data will help inform clinicians discussing medical cannabis usage with orthopaedic trauma patients moving forward.
