Prevalence of upper limb pain and disability and its correlates with demographic and personal factors

Text neck is not associated with neck and upper limb disability in young adults who use smartphones

PURPOSE

The objective of the present study was to correlate neck and upper-limb disabilities with neck flexion in university students who are smartphone users. While handling smartphones, a posture with sustained neck flexion known as "Text Neck" is usually adopted, and some authors related to musculoskeletal symptoms on the neck and the upper limb. However, recent studies state that such an association is questionable.

METHODS

This is an observational study when evaluating 192 university students through questionnaires such as the Neck Disability Index (NDI), Disabilities of Arm, Shoulder, and Hand (DASH), besides the maximal neck flexion, grip and lateral pinch strength of the participants.

RESULTS

The sociodemographic questionnaire demonstrated that most participants had used the device for 5 to 10 years, for five or more hours per day. The DASH questionnaire scores presented an average of 7.2 points, while the data regarding grip and lateral pinch strength showed averages of 29.5 kgf and 8.8 kgf, respectively. The NDI questionnaire scores presented an average of 10.5. The average range of motion of the maximum neck flexion was 27°.

CONCLUSION

There was no association between neck flexion with the DASH and NDI or the grip and lateral pinch strength after the correlation and binary logistic regression analyses. The results show that the scores of DASH, NDI, hand grip and lateral pinch strength, have no association with the maximum neck flexion.

Smartphone addiction, musculoskeletal pain and functionality in university students - a observational study

Smartphone addiction and its excessive use could cause musculoskeletal symptoms such neck and upper limb pain. The purpose of this study was to investigate the association between smartphone use and musculoskeletal pain in the upper limbs and neck, as well as to observe the relationship in between smartphone addiction and musculoskeletal pain and upper limb function in university students. It is a cross-sectional, analytical study. A total of 165 university students participated in the research. Each student had their own smartphone. The students answered a structured questionnaire about pain in the upper limbs and neck; the Smartphone Addiction Inventory (SPAI) and the Disabilities of the Arm, Shoulder, and Hand questionnaire (DASH). Prevalence of neck and upper limb pain was 34.0%. Smartphone addiction and its use to play games and listen to music were risk factors to upper limb pain. Moreover, the smartphone addiction and age proved to be risk factors to neck pain. There was correlation between DASH and SPAI scores, and there was association between DASH score and neck and upper limb pain. Being of the female sex and smartphone addiction predicted the risk of incapacity development. We found association between neck and upper limb pain with smartphone addiction. Functional incapacity was associated to neck and upper limb pain. It was predicted by smartphone addiction and being of the female sex.

Construct validity, test-retest reliability, and responsiveness of the Arabic version of the upper limb functional index

BACKGROUND

The upper limb functional index (ULFI) is a widely used self-report outcome measure questionnaire with robust psychometric properties to assess the upper limb musculoskeletal disorders (UL-MSDs). This study aimed to investigate the psychometric properties of the Arabic version of ULFI (ULFI-Ar).

METHODS

In this observational study, 139 patients (87 male, 52 females with mean age of 38.67 ± 13.04 year) with various UL-MSD's, completed the ULFI-Ar, Disability of Arm, Shoulder, and Hand questionnaire (DASH-Arabic), and numeric pain rating scale (NPRS-Arabic). All participants determined the factor structure, and the construct validity. A subgroup of the participants determined test-retest reliability (n = 46) and responsiveness (n = 27).

RESULTS

The ULFI-Ar construct validity obtained by the expletory factor analysis as one-factor structure, demonstrated an excellent test-retest reliability [intraclass correlation coefficient (ICC2:1) = 0.95], measurement error [standard error of measurement (SEM) = 4.43%; minimal detectable change at 90% confidence interval (MDC90) = 10.34%], medium internal responsiveness [Cohen's d = 0.62 and standard response of mean (SRM) = 0.67], strong external responsiveness DASH-Arabic (r =-0.90; p < 0.001), and negative strong correlation with NPRS-Arabic (r =-0.75, p < 0.001).

CONCLUSIONS

The ULFI-Ar is a valid, reliable, and responsive self-report questionnaire to assess UL-MSDs in Arabic speaking patients.

Telerehabilitation for upper limb disabilities: a scoping review on functions, outcomes, and evaluation methods

Background

Upper limb (UL) disabilities have attracted worldwide attention due to the high economic costs of health care and the negative effects on the quality of life of patients with these disabilities. Telerehabilitation technologies are one of the most important ways to reduce rehabilitation costs and increase the quality of life of patients. Therefore, the aim of this study was to investigate the role of telerehabilitation in improving the health status of patients with upper limb disabilities.

Methods

This scoping review was conducted by searching the Web of Science, PubMed, and Scopus until July 30, 2021. We used a data extraction form with 18 fields to extract data from primary studies. The selection of articles and data extraction was made by four researchers using a data collection form based on inclusion and exclusion criteria. Disagreements were resolved through consultation with the fifth and sixth researchers.Inclusion criteria were studies published in English, studies on upper limb disability, and telerehabilitation based on any technology (synchronous telerehabilitation, asynchronous, or both). Exclusion criteria were articles that did not focus on telerehabilitation and upper limb disabilities. Also, books, book chapters, letters to the editor, and conference abstracts were also removed.

Results

A total of 458 articles were retrieved, and after removing irrelevant and duplicate articles, 29 articles were finally included in this review. Most telerehabilitation was performed for patients with stroke (65%). Among the 15 different services provided with telerehabilitation technologies, "Evaluation of exercises and also a musculoskeletal function of patients by the therapist","Recording of patients' rehabilitation exercises and sending them to the therapist” and "Prescribing new rehabilitation exercises by the therapist" were the most widely used services, respectively. Virtual reality technologies, smart wearables, and robots were used to provide telerehabilitation services. Among the 13 types of evaluation used for telerehabilitation systems, “Evaluation and measurement of upper limb function” was the most used evaluation in the studies. "Improvement in musculoskeletal functions”, "Increasing patients' interest and motivation to perform rehabilitation exercises", and "Increasing adherence to rehabilitation exercises and greater participation in treatment processes" were the most important outcomes, respectively.

Conclusion

Our findings indicate that telerehabilitation provides individuals with equitable access to rehabilitation services, improves musculoskeletal function, and empowers individuals by providing a variety of rehabilitation capabilities.

Musculoskeletal disorders in video gamers - a systematic review

Background

Video gaming is a recreational activity with yearly increasing popularity. It is mostly a sedentary behavior combined with repetitive movements of the upper limbs. If performed excessively, these movements may promote strain injuries and a sedentary lifestyle is one of the contributing factors to musculoskeletal disorders. Therefore, a systematic review was conducted to evaluate if video gaming negatively affects the musculoskeletal system of video gamers.

Methods

PubMed, Web of Science and The Cochrane Library were systematically searched in order to identify relevant peer reviewed original articles in English published between 2000 and 2021. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) method was used for the analysis. Studies were included when they contained investigations of changes of the musculoskeletal system due to video gaming in healthy individuals. Studies with participants older than 60 years or solely psychological, social or cardiovascular outcomes were excluded. An adapted version of the Newcastle–Ottawa Scale was used for the risk of bias analysis.

Results

Sixteen observational studies involving a total of 62,987 participants met the inclusion criteria. A majority (11) of the studies reported statistical negative musculoskeletal changes due to video game playtime. Four studies did not report changes and one study found no effect of video game playtime on the musculoskeletal system. Out of the eleven studies, which demonstrated a negative impact of video game playtime on the musculoskeletal system, the most reported painful body parts were the neck (n = 4), shoulder (n = 4) and back (n = 3). Ten studies reported odds ratios (OR) for the dependence of the appearance of musculoskeletal disorders on video game playtime. In eight studies OR were significantly increased (1.3—5.2).

Conclusion

Eleven out of twelve studies demonstrated a negative impact of video game playtime on the musculoskeletal system. In particular, excessive video game playtimes (> 3 h/day) seemed to be a predictor for the appearance of musculoskeletal disorders. Due to their great popularity across multiple generations, specific and tailored prevention and health promotion programs for video gamers need to be developed to counteract this important public health issue.

Predictors of neck disability among undergraduate students: A cross-sectional study

BACKGROUND: Many cross-sectional studies have examined the predictors of neck pain among adolescents and working-age populations, but there are limited studies included undergraduate students. OBJECTIVE: To investigate the predictors of neck disability among undergraduate students. METHODS: A cross-sectional study using a self-administered online survey. Students completed the survey that included socio-demographic factors, academic-related factors, health and lifestyle factors, and standardized questionnaires including Neck Disability Index (NDI), 12-Item Short-Form Health Survey (SF-12), Depression Anxiety Stress Scales (DASS-21), and Pittsburgh Sleep Quality Index (PSQI). Students who reported an NDI score higher than 15 were considered as having a neck disability. A multivariable logistic regression model was used to identify the significant predictors of neck disability. RESULTS: Of all students (n = 1292), 20.8% reported neck disability. Among all possible predictors, students’ major satisfaction (OR 1.46 [95% CI 1.06–2.01]; p = 0.019), DASS-21 anxiety score (OR 1.06 [95% CI 1.03–1.09]; p < 0.001), SF-12 total score (OR 0.89 [95% CI 0.86–92]; p < 0.001), and PSQI score (OR 1.21 [95% CI 1.15–1.28]; p < 0.001) were the only significant predictors of neck disability. CONCLUSIONS: Increased levels of academic stressors and anxiety, and decreased levels of quality of life and sleep quality are associated with increased neck disability among undergraduate students.

Cross-cultural adaptation of the upper limb functional index in Arabic

BACKGROUND AND AIM

The upper limb functional index (ULFI) is a widely used self-reported outcome measure questionnaire with robust psychometric properties to assess the upper limb musculoskeletal disorders (UL-MSDs). This study aimed to adapt the ULFI cross-culturally in Arabic (ULFI-Ar) and to examine its face validity, content validity, internal consistency, criterion validity, and interpretability.

METHODS

In this observational cross-sectional study, the English version of ULFI was cross-culturally adapted to the Arabic language through double forward and backward translations, following the recommended guidelines. Interviews with participants and reviews by experts were used to assess the face and content validity of the prefinal version of ULFI-Ar. Internal consistency was determined by Cronbach's alpha coefficient (a). Criterion validity was analyzed by correlating the ULFI-Ar with the Arabic version of the Disabilities of the Arm, Shoulder, and Hand (DASH-Arabic) using Pearson's correlation coefficients.

RESULTS

A total of 54 participants reported no major language barriers or difficulties in completing the ULFI-Ar. The participants' interview demonstrated adequate face validity. The review by experts showed that the content validity was excellent (content validity index = 0.81 - 1.00 for each item and 0.96 for the scale). The ULFI-Ar showed high internal consistency (a = 0.88). For criterion validity, there was strong correlation with the DASH-Arabic (r = -0.802, p < 0.0001) and moderate correlation with NPRS-Arabic (r = -0.502, p < 0.0001).

CONCLUSIONS

The ULFI-Ar was easy to complete with no linguistic difficulties. The results demonstrate the suitability of using the ULFI-AR for Arabic-speaking patients with UL-MSD.

Cross-cultural adaptation, validity, and reliability of the Persian version of the Upper Limb Functional Index

Introduction

The Upper Limb Functional Index (ULFI) is a patient-reported outcome measure (PROM) designed to evaluate both the functional status and the level of participation in patients with upper limb musculoskeletal disorders (ULMSDs). The purpose of this study was translation, cross-cultural adaptation, and psychometric evaluation of the original ULFI into Persian (ULFI-Pr).

Methods

The original ULFI was translated into Persian through double forward and backward translations. Consecutive symptomatic upper limb patients (n = 180, male = 60%, age = 38.21 ± 7.13) were recruited and completed the ULFI-Pr and the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaires. Internal consistency and test-retest reliability were determined using Cronbach's Alpha and the Intra-class Correlation Coefficient (ICC2.1). Criterion validity was analyzed by evaluating the Pearson's r correlation coefficient between the ULFI-Pr and DASH questionnaires. Construct validity was examined through exploratory factor analysis (EFA) using Maximum Likelihood Extraction with Promax rotation.

Results

The original ULFI was translated and cross-culturally adapted into Persian with only minor wording changes. The ULFI-Pr demonstrated high levels of internal consistency (α = 0.91) and test-retest reliability (ICC2.1=0.92). The correlation between the ULFI and DASH was high (r = 0.71). The EFA demonstrated a one-factor structure that explained 38.2% of total variance. No floor or ceiling effects were observed.

Conclusion

The ULFI-Pr can be considered as a region-specific, single-factor structure PROM for evaluation of patients with upper limb disorders for clinical and research purposes in Persian language populations.
