Work-related musculoskeletal disorders in physical therapists: a prospective cohort study with 1-year follow-up

A systematic review of work related musculoskeletal disorders among physical therapists and physiotherapists

Physical therapists and physiotherapists (PPTs) perform and repeat physical tasks that can lead to work-related musculoskeletal disorders (WMSD). The aim was to study the main research concerning this problem, i.e. the risk factors, activities that exacerbate WMSD symptoms, alterations in work habits and the proposed responses, and to estimate mean value (±standard deviation, STD) for the most studied parameters. This review was conducted according to the PRISMA guideline. Five databases (Pubmed, ScienceDirect, Google Scholar, Medeley and Science.gov) were scanned to identify works investigating the different aspects of WMSD among PPTs. Two reviewers independently selected relevant studies using inclusion/exclusion criteria, critically appraised, and extracted data. To homogenize the data, prevalence were reported to the total sample studied when necessary. Among the 9846 articles identified, 19 articles were included. The WMSD prevalence was over 50 %. The areas most affected were the lower back, neck and thumb. An exhaustive list of parameters were constructed for job risk factors (n = 19), activities that exacerbating symptoms (n = 13), altered work habits (n = 15), responses and treatments (n = 26). The mean prevalence (±STD) was calculated for the major parameters. Nine main job risk factors were extracted with an average prevalence of about 30 % and a relatively high variability. Seven activities exacerbating WMSD symptoms and five altered work habits were identified with a homogeneous rate (5-20 %). Three main responses and treatments were found with heterogeneous prevalence. This review provides useful results for the development of future protocols to prevent the occurrence of WMSD among PPTs and meta-analyses.

Prevalence and risk factors of work-related musculoskeletal disorders among physical therapists in Ho Chi Minh City, Vietnam

BACKGROUND

Understanding risk factors linked to work-related musculoskeletal disorders (WMSDs) is crucial for enhancing health promotion and ensuring workplace safety among healthcare professionals particularly physical therapists (PTs). However, in Vietnam, there has been lack of an investigation. Therefore, this study was to determine whether potential risk factors contributed to the occurrence of WMSDs among PTs in Ho Chi Minh City.

METHOD

An online self-reported questionnaire for WMSDs comprising the Nordic Musculoskeletal Questionnaire (NMQ), Job-risk and Environmental factors, the Perceived Stress Scale (PSS-4) and the coping strategies, were distributed to PTs. They were enrolled if they had: age ≥ 22 years, graduated from PT program, a full-time job with ≥1 year of experience. Unadjusted and adjusted odds ratios (ORs) with 95% confidence intervals (CIs) were determined using Logistic regression.

RESULTS

Our study found that within the past 12 months, the prevalence of WMSDs was 76.4% (n = 204/267): neck 58.4% and lower back 57.3%. PTs aged 22-29 years, < 4 years of education, and < 7 years of working experience were more likely to have WMSDs 2-3 times than those who did not. After adjusting for age, education, and work experience, PTs who engaged in manual techniques/exercises, lifting/transferring patients, and maintaining awkward postures were 5-7 times more likely to have WMSDs in the neck and lower back than those who did not. Environmental and psychological factors, such as number of treatment tables, size of electrotherapy rooms, using PTs modalities, and stress were significantly associated with WMSDs. More than 50% of PTs used modified positions and new treatment/techniques that did not aggravate their symptoms, as coping strategies.

CONCLUSIONS

This study indicates potential risk factors associated with WMSDs, affecting the neck and lower back among PTs in Vietnam. These risk factors should be addressed to improve overall PTs health, retain skilled workers, and encourage them to continue working.

Work-related injury or work-related pain? A qualitative investigation of work-related pain and injury management among rehabilitation professionals1

BACKGROUND

Patient mobility tasks place rehabilitation professionals (Physical and Occupational Therapists) working in hospitals at high risk for work-related musculoskeletal disorders (WMSDs). However, when investigating engagement with a Safe Patient Handling and Mobility program (SPHM), administrative records at a level one trauma hospital showed that rehabilitation professionals reported zero work-related injuries over an eight-year period.

OBJECTIVE

As part of a qualitative study conducted to discover their unique work experiences, we explored some of the reasons that rehabilitation professionals might not report work-related injuries to their employers.

METHODS

Using a collective case study design, six focus groups were conducted with 25 members of the rehabilitation team within a level-one trauma hospital. Focus groups were recorded; transcripts were analyzed for emergent themes using first and second cycle coding procedures.

RESULTS

Participants in this study denied experiencing work-related injuries but frequently described working in pain, often attributed to patient mobility tasks. These experiences were not reported to employers. Self-management of their pain through co-worker treatment, over-the-counter medications, or informal alteration in job tasks were reported as common.

CONCLUSION

Administrative injury records may underrepresent injuries among rehabilitation professionals. This may be due to their perception of work-related pain as something different than work-related injuries, or that many of these rehabilitation professionals treat their own work-related pain and symptoms rather than report them. To get a more accurate assessment of injury frequency among rehabilitation professionals, researchers should gather information directly from the participants, and should inquire about work-related pain in addition to injury.

Association of electronic learning devices and online learning properties with work-related musculoskeletal disorders (WMSDs): A cross-sectional study among Thai undergraduate students

Computers and mobile devices are becoming the primary instruments used by students worldwide in all facets of their working and learning activities. This study aimed to investigate the relationship between the use of electronic devices, the characteristics of learning properties, and the potential predictors of work-related musculoskeletal disorders (WMSDs) among Thai undergraduate students. In this cross-sectional study, data were collected using Microsoft Forms with an online self-administered scale. The research instrument comprised four categories: demographic and health history characteristics, online learning properties, psychological health, and perceived WMSDs. Using multistage sampling, 4,618 samples were collected from 18 schools nationwide. A total of 3,705 respondents were eligible for the analysis. Descriptive statistics, chi-square, and binary logistic regression analyses were used for the data analysis. The results showed that the majority of the respondents had online learning only in some semesters/subjects (67.3%), used mobile phones for learning (43.3%), had an appropriate desk workstation (66.1%), used non-office chairs (76.0%), spent prolonged periods sitting (91.6%), had a bent posture while sitting (78.2%), had a private working space/room (92.4%), had proper lighting (85.4%), and experienced normal levels of stress (81.1%). Overall, 42.1% of Thai university students experienced WMSDs in any area of the body in the prior 6 months. Six significant predictors (p = 0.05) of WMSDs were obtained from the multivariate analysis, including stress, use of electronic devices, bent posture, prolonged sitting, year of study, and online learning classes (The adjusted odds ratio ranged from 1.43 to 3.67). High-risk students who mostly used mobile learning devices should be prescribed interventions to reduce stress, develop postural awareness and skills, emphasize positioning solutions, and reduce extended sitting time. The results indicated that preventive measures are warranted and required because the risk predictors were identified as preventable.

Preliminary evaluation of an automated robotic transfer assist device in the home setting

PURPOSE

The purpose of this study was to examine the effects of six weeks of routine use of a novel robotic transfer device, the AgileLife Patient Transfer System, on mobility-related health outcomes, task demand, and satisfaction relative to previous transfer methods.

MATERIALS AND METHODS

Six end users and five caregivers used the system in their homes for six weeks. Participants completed several surveys examining perceived demands related to preparing and performing a transfer and mobility-related health outcomes pre and post intervention. Participants were also asked about their satisfaction with using the technology compared to previous transfer methods.

RESULTS

Both end users and caregivers reported reduction in perceived physical demand (p = 0.007) and work (p ≤ 0.038) when preparing for and performing a transfer. End users indicated that the device intervention had a positive impact, indicating some improvements to health-related quality of life as well as improved competence, adaptability, and self-esteem post-intervention. All participants were highly likely to recommend the technology to others.

CONCLUSION

The AgileLife Patient Transfer System is a promising new form of transfer technology that may improve the mobility and mobility-related health of individuals with disabilities and their caregivers in home settings.Implications for rehabilitationRobotic transfer assistance reduced physical demand and work among end users and caregivers.The robotic device had a positive impact on some quality of life outcomes after 6 weeks of use.Users were highly likely to recommend the robotic transfer device to others.

Effects of different bed heights on the physical burden of physiotherapists during manual therapy: an experimental study

This study aimed to determine the effect of physiotherapists' physical burden caused by different bed heights during manual therapy. Thirty-three male physiotherapists performed tasks simulating lumbar massage and passive hip abduction range-of-motion exercise (ROM) on the beds with low height (LH) and adjusted height (AH), with each task performed three times. The anterior inclination angle of the physiotherapist's trunk was measured, the surface electromyograms of the erector spinae and trapezius muscles were recorded, and perceived stress was assessed. The indexes obtained were statistically compared for different bed heights. Additionally, the lumbar disc compression force and flexion torque were estimated. The lumbar burden caused by the excessive bending and the biomechanical burden and perceived stress were stronger at LH than AH. In ROM tasks using the right hand, the muscle activity was lower at the left lumbar region at LH than at AH. At LH, the anterior inclination angle increased and the lumbar muscle activity declined as the number of tasks increased. The burden on the shoulders was not significantly different by bed heights. Our results showed that, when physiotherapists perform manual therapy, it is necessary to adjust the bed height to reduce physical burden and ensure higher quality of service.

Global prevalence of musculoskeletal disorders among physiotherapists: a systematic review and meta-analysis

BACKGROUND

Musculoskeletal disorders (MSD) are one of the most important problems among physiotherapists worldwide. However, there is no meta-analysis of the MSD prevalence in all body areas among physiotherapists.

OBJECTIVES

The purpose was to investigate and estimate the worldwide prevalence of MSD among physiotherapists using a systematic review-, meta-analysis and meta-regression.

METHODS

The systematic review, meta-analysis and meta-regression were performed in 2022 using the PRISMA guidelines.

DATA SOURCES

The search was performed on PubMed/Medline, ScienceDirect, Google Scholar, Medeley and Science.gov databases.

STUDY APPRAISAL

The quality appraisal of the included articles was assessed using the critical appraisal tool for cross-sectional studies AXIS.

RESULTS

A total of 722 articles were found. After screening and comparison with the inclusion criteria, 26 studies were retained. Based on the random-effects model, the worldwide MSD prevalence in neck, upper back, mid back, lower back, shoulders, elbows, wrists/hands, thumb, hips/thighs, knees/legs, and ankles/feet was 26.4% (CI 95%: 21.0-31.9%), 17.7% (CI 95%: 13.2-22.2%), 14.9% (CI 95%: 7.7-22.1%), 40.1% (CI 95%: 32.2-48.0%), 20.8% (CI 95%: 16.5-25.1), 7.0% (CI 95%: 5.2-8.9), 18.1% (CI 95%: 14.7-21.5%), 35.4% (CI 95%: 23.0-47.8), 7.0% (CI 95%: 5.2-8.8), 13.0% (CI 95%: 10.3-15.8), and 5% (CI 95%: 4.0-6.9) respectively. The neck and shoulder prevalence of four continents were close to the world prevalence. No effect of continent was found on MSD prevalence. The heterogeneity of the results obtained in the meta-analysis and meta-regression was discussed.

CONCLUSIONS

Based on the random effects model, the results of the worldwide meta-analysis showed that lower back pain, thumb, neck and shoulder were the area most at risk for MSD and were therefore those to be monitored as a priority. Recommendations were proposed for future reviews and meta-analyses.

Work-Related, Non-Specific Low Back Pain among Physiotherapists in France: Prevalence and Biomechanical and Psychosocial Risk Factors, as a Function of Practice Pattern

BACKGROUND

Physiotherapists worldwide experience lower back pain (LBP). Up to 80% of physiotherapists report having experienced an episode of LBP at some point in their career, and LBP is the most common musculoskeletal disorder in this profession. In France, the prevalence of LBP among physiotherapists and associated work-related risk factors have not previously been studied.

OBJECTIVE

To determine whether the risk of work-related non-specific LBP among French physiotherapists depends on practice pattern.

METHOD

A link to an online self-questionnaire was sent to French physiotherapists. The various practice patterns were compared with regard to the prevalence of LBP, the total number of days with LBP during the previous 12 months, and the degree of exposure to biomechanical, psychosocial and organisational risk factors.

RESULTS

Among the 604 physiotherapists included in the study, the prevalence of work-related, non-specific LBP in the previous 12 months was 40.4%. The prevalence was significantly greater among physiotherapists working in geriatrics (p = 0.033) and significantly lower in sports medicine (p = 0.010). Differences in exposure to risk factors were also found.

CONCLUSIONS

The risk of non-specific LBP among French physiotherapists appears to depend on the mode of practice. All the various dimensions of risk must be taken into account. The present study could serve as a basis for more targeted research on the most exposed practices.

Neck Disability Index Detects Higher Neck-Related Disability Levels among Physiotherapists and Family Medicine Specialists than among Dentists

BACKGROUND

Healthcare workers who are in physical contact with patients are prone to work-related musculoskeletal disorders (WMSDs). Much is known about the prevalence of neck pain, but the extent of disability associated with neck pain among physical therapists (PTs), dentists, and family medicine specialists (FMs) is unknown.

METHODS

The prevalence of neck pain and Neck Disability Index (NDI) data were collected from 239 PTs, 103 FMs, 113 dentists, and 112 controls from June to August 2022.

RESULTS

The highest prevalence of neck pain was found in FMs (58.3%), followed by dentists (50.4%), PTs (48.5%) and controls (34.8%). The NDI% in PTs and FMs had higher values than controls: 14.6 ± 12.4, p = 0.02 for PTs, 14.9 ± 12.4, p = 0.01 for FMs vs. 10.1 ± 10.1 controls. The dentist group did not differ from controls (11.9 ± 10.2, p = 0.13). Mild, moderate, or severe forms of disability were more common in medical professionals than in controls (44.2%, 9.5%, and 1.5% vs. 37.5%, 7%, and 0%). Dentists were the youngest group with high functionality and the lowest degree of disability, comparable to the control population. Gender or age had no effect on NDI scores in this population. FMs, who represented the oldest group, showed age dependency (eleven years older in higher disability groups). Gender had no effect on NDI. In PTs, females predominated in all disability categories and PTs became five years older with increasing disability level.

CONCLUSION

By using NDI in assessing neck-related WMSDs, we can detect medical professionals prone to more serious disability and potentially plan preventive actions.

Prevalence of Body Area Work-Related Musculoskeletal Disorders among Healthcare Professionals: A Systematic Review

Healthcare professionals perform daily activities that can lead to musculoskeletal disorders (MSDs). The objective of this review was to summarize these MSDs by body areas in relation to healthcare professions. The underlying question is, worldwide, whether there are areas that are more exposed depending on the occupation or whether there are common areas that are highly exposed to MSDs. This issue has been extended to risk factors and responses to reduce MSDs. The review was conducted according to the PRISMA guidelines between February and May 2022. Google scholar and Science Direct databases were scanned to identify relevant studies. Two authors independently reviewed, critically appraised, and extracted data from these studies. Overall and body area prevalence, risk factors, and responses to MSDs were synthetized by occupational activity. Among the 21,766 records identified, 36 covering six healthcare professions were included. The lower back, neck, shoulder and hand/wrist were the most exposed areas for all healthcare professionals. Surgeons and dentists presented the highest prevalence of lower back (>60%), shoulder and upper extremity (35-55%) MSDs. The highest prevalence of MSDs in the lower limbs was found for nurses (>25%). The main causes reported for all healthcare professionals were maintenance and repetition of awkward postures, and the main responses were to modify these postures. Trends by continent seem to emerge regarding the prevalence of MSDs by healthcare profession. Africa and Europe showed prevalence three times higher than Asia and America for lower back MSDs among physiotherapists. African and Asian nurses presented rates three times higher for elbow MSDs than Oceanians. It becomes necessary to objectively evaluate postures and their level of risk using ergonomic tools, as well as to adapt the work environment to reduce exposure to MSDs with regard to the specificities of each profession.

Effects of a Family Caregiver Care Programme in Musculoskeletal Pain and Disability in the Shoulder-Neck Region-A Randomised Clinical Trial

Life expectancy in Spain has increased and older people need more health care to improve their quality of life. The high demands of the population sometimes collapse health services, making them insufficient to cover their needs, which leads to the development of “non-professional caregivers”. These caregivers have suffered musculoskeletal injuries of the cervical spine and shoulders and should be guided and assessed on ergonomics, biomechanics, or kinesiotherapy. However, there are no interventions to help them care for themselves. This study presents the application of a physical exercise programme to prevent these disorders in women caregivers of dependent patients. It consists of a randomised controlled clinical trial with two groups: both received a family caregiver care programme, and the intervention group also received a physical therapeutic exercise programme for 12 weeks. A total of 62 caregivers completed the study, who were mostly daughters or wives of dependents. Of these, 70.97% presented a “moderate” pain intensity and a cervical disability of 13.72 ± 7.64 points in the NDI questionnaire in the initial evaluation. In the intervention group of caregivers, there was a significant decrease in the pain intensity and a significant increase (p < 0.05) in all cervical joint amplitude movements. Caregivers present a high prevalence of musculoskeletal disorders. The physical exercise programme was effective in reducing the intensity of pain, lumbar disability, and cervical disability of the family caregivers.

Prevalence of work-related musculoskeletal disorders among health care professionals: A systematic review

BACKGROUND

Work-related musculoskeletal disorders (WRMSDs) are one of the main causes of morbidity among healthcare professionals. It has various secondary consequences on productivity by diminishing the quantity and quality of work completed by the affected personnel, in addition to having a primary impact on the individual with pain and discomfort.

OBJECTIVE

The study aims to determine the overall prevalence rate of WRMSD among dentists, physiotherapists, and surgeons and also identify the commonly affected regions of the body about specific health care professions among each of the three professions, as recorded by the cross-sectional studies performed in various countries and regions of the world.

METHODS

A systematic search strategy was framed following the PRISMA guidelines based on the present inclusion and exclusion criteria. A critical search of articles was conducted during June 2020 in CINAHL (DOAJ), PubMed, Google Scholar Scopus, PEDro databases and SAGE journals.

RESULTS

Out of the 42 articles that met the eligibility criteria, there were 39 cross-sectional studies, 2 pilot cross-sectional surveys and 1 prospective cohort study with one-year follow-up. All studies included in this review used various survey tools for recording the demographic details and measuring the prevalence of WRMSDs and other outcome factors.

CONCLUSION

We conclude that all three health care professionals (dentists, physiotherapists and surgeons) are highly prone to develop WRMSDs with surgeons and dentists being more vulnerable when compared to physiotherapists. The lower back and neck are identified as the two most commonly affected regions among all three professionals.

Pediatric Occupational Therapists and Occupational Stress: A Scoping Review

The purpose of this scoping review was to provide further insight into the stress and the stressors experienced by pediatric occupational therapists in the work environment. Using the Arksey and O'Malley framework, the search was conducted in eight databases, nine electronic journals, and eight gray literature sources to identify articles related to stress and stressors of pediatric occupational therapists. Review selection and characterization were performed by two independent reviewers. Twelve articles published from 2011 to 2020 were identified and varied in terms of purpose, population, and results although the articles all shared similar methodologies and outcome measures. Only 25% of the articles (3/12) addressed pediatric occupational therapy stress and stressors directly while the remaining addressed occupational stress, but with varying levels of attention to pediatric occupational therapists. Stress and stressors experienced by pediatric occupational therapists have been studied to a limited extent. Occupational stress is associated with increased burnout, decreased health, and decreased job satisfaction and performance. Several knowledge gaps have been identified, as well as priorities for future research into pediatric occupational therapists and occupational stress.

The impact of manual patient handling on work ability: A cross-sectional study in a Brazilian hospital

Aim

To investigate the level of self‐reported work ability and its association with manual patient handling in healthcare workers.

Design

Cross‐sectional study adhering to the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines.

Methods

A total of 320 healthcare workers answered a self‐administered questionnaire regarding manual patient handling, work ability, occupational factors, occurrence of low back pain and sociodemographic and lifestyle factors from November 2016 to March 2017. The association between manual patient handling and low back pain was analysed with Poisson regression models.

Results

The prevalence ratio of inadequate work ability was 43.42%. Manual patient handling (PR 1.375, 95% CI 1.038–1.821), bachelor education (PR 2.150, 95% CI 1.272–3.632), less than bachelor education (PR 2.166, 95% CI 1.218–3.855), seniority (PR 1.049, 95% CI 1.024–1.086), poor sleep quality (PR 1.425, 95% CI 1.13–1.796) and presence of low back pain (PR 2.003, 95% CI 1.314–3.052) were all positively associated with an inadequate work ability.

Prevalence of and prevention for work-related upper limb disorders among physical therapists: a systematic review

Background

Physical therapists (PTs) are at increased risk for development of work-related upper limb disorders (WRULDs) due to the physically intensive, constant hands-on nature of the profession. The objectives of this systematic review were to examine the literature on WRULDs among PTs, specifically the (1) 1-year prevalence, (2) workplace risk factors, (3) consequences, and (4) coping strategies utilized to mitigate WRULDs.

Methods

A comprehensive search of the literature was performed using PubMed, CINHAL, EMBASE, and Google Scholar. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used for conducting this systematic review. Studies that reported the 1-year prevalence of WRULDs among PTs, workplace risk factors for WRULDs, consequences of WRULDs, and coping strategies utilized by PTs were included.

Results

Twelve studies met the inclusion criteria. The 1-year WRULDs prevalence rates varied widely, with thumb disorders having the highest prevalence (7.6-52.5%), followed by wrist and hand disorders (5-66.2%), shoulder disorders (3.2-45.2%), and elbow disorders (4-16%). Reported risk factors included treating a high volume of patients and frequent performance of manual therapy techniques. Consequences included interference with PTs’ personal and professional activities while coping strategies involved alterations to the work environment, techniques used, and workload.

Conclusions

WRULDs remain a persistent threat to the PT workforce, likely due to the hands-on, physically intensive nature of professional activities. An essential strategy to reduce WRULDs is to improve clinicians’ awareness of WRULDs, workplace risk factors, and subsequent consequences of WRULDs. Effective coping strategies are critical to preserve, protect, and prolong PTs’ use of the upper limbs.

Application of the rapid upper limb assessment tool to assess the level of ergonomic risk among health care professionals: A systematic review

BACKGROUND: Work-related musculoskeletal disorders (WMSDs) and ergonomic risk factors are widespread problems in the healthcare sector. OBJECTIVE: The primary objective of this review is to evaluate the application of the Rapid Upper Limb Assessment (RULA) tool in various healthcare professionals and to assess the level of ergonomic risk among them. METHODS: The databases MEDLINE, EMBASE, CINAHL, LILACS, SCIELO, DOAJ, PubMed, and PEDro were searched with terms associated with ergonomics, assessment, health care providers, risk factors, workplace, and RULA. We reviewed the literature from 2000 to 2020, including studies assessing RULA’s effectiveness for evaluating the WMSD’s and ergonomic risk in health care practitioners. We excluded the studies which were not open access and freely available. RESULTS: Overall, 757 records were screened; of these 40 potential studies, 13 different healthcare professionals were identified as eligible for inclusion. In most studies, the RULA tool was established as an effective tool in application and evaluating the level of the ergonomic risk among them. CONCLUSIONS: The RULA tool assessed the high ergonomic risk levels in dental professionals and low ergonomic risk levels in professionals working in the pharmacy department, clearly suggesting potential changes in work postures were necessary to prevent or reduce these risk factors.

Assessing physical workload among people with musculoskeletal disorders: validity and reliability of the physical workload questionnaire

Background

Demands of physical work are related to musculoskeletal disorders, and hence, important to assess. The Physical Workload Questionnaire (PWQ) is based on 26 items related to physical workload. The PWQ has been translated into Norwegian, but its psychometric properties have not yet been tested. The aim of this study was to assess the validity and reliability of the PWQ among patients with musculoskeletal disorders.

Methods

A cross-sectional study with a test-retest design was conducted to assess construct validity (structural validity and hypothesis testing) and reliability (internal consistency and test-retest reliability) among employed patients with musculoskeletal disorders. Exploratory factor analysis was performed to assess the structural validity and number of items to be included in the Norwegian version of the PWQ. Hypothesis testing was assessed by 14 a priori hypotheses (“known” group, convergent and discriminant validity). Internal consistency was evaluated using Cronbach’s alpha and test-retest reliability by Intraclass Correlation Coefficient (ICC_2.1), Standard Error of Measurement (SEM_agreement) and Smallest Detectable Change (SDC_95%ind).

Results

In total, 115 patients with a mean age (SD) of 46 (9) years were included, of which 48 were included in the reliability analyses. Exploratory factor analysis resulted in two subscales: “Heavy physical work” (15 items, range 0–100) and “Long-lasting postures and repetitive movements” (7 items, range 0–100). No floor or ceiling effects were seen in the subscales. Twelve of the 14 (85%) predefined hypotheses were confirmed. The internal consistency with Cronbach’s alpha was 0.94 and 0.85 on subscales 1 and 2, respectively. Test-retest reliability analyses demonstrated an ICC_2.1 of 0.96 (95% CI 0.88, 0.98) and 0.92 (95% CI 0.81, 0.96), SEM of 6.9 and 10.0 and SDC_95%ind of 19.2 and 27.7 of subscales 1 and 2, respectively.

Conclusions

The Norwegian version of the PWQ demonstrated good validity and reliability and can be used to evaluate physical workload in patients with musculoskeletal disorders.

Work-related musculoskeletal disorders among physical therapists in Taiwan

Work-related musculoskeletal disorders (WMSD) refer to musculoskeletal injuries caused by the occupation. Physical therapists (PTs) suffer from a high risk of WMSD despite their extensive knowledge in ergometrics and injury prevention. This study aims to discover the incidence and prevalence of WMSD among PTs using Taiwan's nationwide claims database. The trend of annual patients seeking rehabilitation and the prevalence of WMSD among PTs were presented. The age- and gender-specific incidence of WMSD were also calculated. The prevalence of WMSD in PTs varied from 6.1% to 75.2%, and the incidence ranged from 6.1 to 29.1 per 100 person-years during 1997 and 2012. For those aged ≤30 years, the incidence was higher in females than males (incidence rate ratio  = 1.08, 95% confidence interval [CI]: 1.02-1.14, P = .011), whereas for those aged from 31 to40 years, females had lower incidence of WMSD than males (incidence rate ratio  = 0.88, 95% CI: 0.80-0.96, P = .007). The patients/PTs ratio was higher (270.56-337.74) in 1998 and 2004 to 2007 and became stable (245.93-252.82) in 2008 to 2012, correlating with a rise in the WMSD prevalence in 1999 to 2007 and a steady prevalence after 2008 (63.5%-66.3%) in PTs. In conclusion, the risk of WMSD among PTs was positively correlated to the frequency of patients seeking rehabilitation service. In addition, age and gender were important risk factors for developing WMSD among PTs.

Occupational injuries and patient lift usage among physical rehabilitation therapists

BACKGROUND

Physical therapists (PTs) and physical therapist assistants (PTAs) are at high risk for work-related musculoskeletal pain and discomfort.

OBJECTIVE

Determine the prevalence and exposure risk factors for work-related injuries (WRIs) among rehabilitation PTs and PTAs.

METHODS

A cross-sectional research survey was conducted among 170 PTs and 67 PTAs at 51 free-standing rehabilitation hospitals and rehabilitation units embedded in general hospitals in the Midwestern states of Iowa, Kansas, Missouri and Nebraska. The prevalence of WRIs and significant risk factors for developing WRIs were determined for PTs and PTAs.

RESULTS

The 1-year prevalence of WRIs among PTs and PTAs working in physical rehabilitation was 29.5%. Multifaceted causes were identified including frequently bending/twisting, over-exerting force during patient handling activities, inadequate lifting devices, and lack of ongoing training for mechanical lifting device usage.

CONCLUSIONS

Equipment usage barriers point to a critical need for technology creation, research, and education to advance worker safety while simultaneously enhancing patient outcomes.

Walking improvement in chronic incomplete spinal cord injury with exoskeleton robotic training (WISE): a randomized controlled trial

STUDY DESIGN

Clinical trial.

OBJECTIVE

To demonstrate that a 12-week exoskeleton-based robotic gait training regimen can lead to a clinically meaningful improvement in independent gait speed, in community-dwelling participants with chronic incomplete spinal cord injury (iSCI).

SETTING

Outpatient rehabilitation or research institute.

METHODS

Multi-site (United States), randomized, controlled trial, comparing exoskeleton gait training (12 weeks, 36 sessions) with standard gait training or no gait training (2:2:1 randomization) in chronic iSCI (>1 year post injury, AIS-C, and D), with residual stepping ability. The primary outcome measure was change in robot-independent gait speed (10-meter walk test, 10MWT) post 12-week intervention. Secondary outcomes included: Timed-Up-and-Go (TUG), 6-min walk test (6MWT), Walking Index for Spinal Cord Injury (WISCI-II) (assistance and devices), and treating therapist NASA-Task Load Index.

RESULTS

Twenty-five participants completed the assessments and training as assigned (9 Ekso, 10 Active Control, 6 Passive Control). Mean change in gait speed at the primary endpoint was not statistically significant. The proportion of participants with improvement in clinical ambulation category from home to community speed post-intervention was greatest in the Ekso group (>1/2 Ekso, 1/3 Active Control, 0 Passive Control, p < 0.05). Improvements in secondary outcome measures were not significant.

CONCLUSIONS

Twelve weeks of exoskeleton robotic training in chronic SCI participants with independent stepping ability at baseline can improve clinical ambulatory status. Improvements in raw gait speed were not statistically significant at the group level, which may guide future trials for participant inclusion criteria. While generally safe and tolerable, larger gains in ambulation might be associated with higher risk for non-serious adverse events.

Ergonomic assessment of work-related musculoskeletal disorder and its determinants among commercial mini bus drivers and driver assistants (mini bus conductors) in Nigeria

Introduction

Work-related musculoskeletal disorder (WMSD) is a leading causes of occupational injury and disability among drivers and workers in the transport industry. This study evaluated the ergonomically assessed WMSD and its determinants among Nigerian commercial mini bus drivers (BD) and mini bus conductors (BC)

Method

A total of 379 participants (BD = 200, BC = 179) were purposively sampled for this exploratory cross-sectional study. Participants’ WMSD and work related variables were respectively assessed using the standardized Nordic questionnaire and a content-validated, Driving Work Station Assessment (DWSA) form. Data were analyzed descriptively and inferentially using chi-square and logistic regression. The level of significance was set at α = 0.05.

Results

The participants were aged between 20 and 66 years, with a mean age of 33.26±10.76years (BD = 38.42±10.22years, BC = 27.50±8.13years); most of whom consumed alcohol (84.4%) and experienced severe job stress (73.4%). There was a high prevalence (95.8%; BD = 94.5%, BC = 97.8%) of WMSDs, the lower back (66.8%) and upper back (54.1%) had the highest regional prevalence of WMSD. The BC (BC vs BD) had significantly (p<0.05) higher prevalence of Neck (47.7% vs 21.5%) and upper back (80.4% vs 30.5%) WMSDs. Conversely, the BD (BD vs BC) had significantly (p<0.05) higher prevalence of low-back (85.0% vs 46.4%), knee (25.0% vs 9.5%), elbow (11.5% vs 3.9%), and wrist (10.5% vs 3.4%) WMSD. There was a significant association between WMSD and each of work duration (X² = 11.634, p = 0.009), work frequency (X² = 8.394, p = 0.039), job dissatisfaction (X2 = 10.620, p = 0.001) and job stress (X² = 16.879, p = 0.001). Working beyond 4days/week (OR = 10.019, p = 0.001), job dissatisfaction (OR = 1.990, p = 0.031), constrained working postures (OR = 5.324, p = 0.003) and fatigue (OR = 4.719, p = 0.002) were the predictors of WMSD.

Conclusion

Job stress, work duration and work frequency, posture and fatigue are important determinants of WMSDs among mini bus drivers and their assistants in Nigeria. Ergonomics training intervention for this population is recommended.

Impact of Job Resources and Job Demands on Burnout among Physical Therapy Providers

Job burnout is a threat for physical therapists. Little research has been conducted to identify possible protective factors against burnout in this population. Accordingly, we utilized the job demands-resources (JD-R) model and self-determination theory to guide our examination of basic psychological needs as factors to predict burnout in physical therapists. One hundred and two licensed physical therapists completed surveys. Higher levels of autonomy, competence and relatedness predicted burnout, even after accounting for job demands. Job resources, such as the basic psychological needs outlined by the self-determination theory, along with perceived respect, buffer the negative effects of secondary trauma on burnout. The job resource of perceived respect also buffers the negative effects of the physical demands of the job on burnout. These findings suggest that while job demands can be difficult to change, increasing the fulfillment of job resources can help ameliorate burnout in physical therapists. The present findings highlight the need for workplace interventions which cultivate the satisfaction of the basic psychological needs of autonomy, competence, and relatedness to address burnout among physical therapists.

Prevalence and risk of spinal pain among physiotherapists in Poland

Background

The purpose of this study was to determine the prevalence, symptoms of, and risk factors for spinal pain in physiotherapists, as well as to analyse the correlation between these factors and the nature of the work, anthropometric features of the respondents, and the level of their physical activity.

Methods

The study was conducted among 240 physiotherapists (71 male and 169 female) with a mean age of 38.7 years. They were divided into three groups: physical therapy (37), kinesitherapy (158) and massage (45). Physiotherapists were evaluated with a specially designed questionnaire, the postural discomfort chart, the Neck Disability Index (NDI) questionnaire, and the Oswestry Disability Index (ODI) questionnaire.

Results

The analysis showed a 91.7% incidence of spinal pain in physiotherapists (91.1% for kinesitherapy, 97.3% for physical therapy, and 88.9% for massage). The study revealed that 50.2% of physiotherapists indicated one to five pain episodes in their careers. Most respondents reported pain in the lumbosacral spine (82%) and the cervical spine (67%). Most respondents (58.5%) scored the pain as moderate (VAS scale). Carrying (62.6%) and torso bending (37.4%) were indicated as the causes of pain.

Conclusions

Physiotherapists demonstrate a high prevalence of spinal pain. Physical activity reduces the frequency of pain episodes.

Job strain in German novice physical therapists / Psychische Beanspruchung am Arbeitsplatz von Berufsanfängern in der Physiotherapie

Introduction

International research shows high levels of job demands and psychological resources for physical therapists, and job strain is considered to be moderate. So far, publications are based on therapists with varying length of service. Little is known about job strain during the first year in the profession.

Aim

To investigate the level of job strain of German novice physical therapists and to identify common workplace stressors.

Methods

We conducted a web-based survey among physical therapists who had been working for 12 month or less. Using a self-administrated questionnaire, job strain was measured by its effects on work commitment, general health, job satisfaction, burnout and turnover intention. Subgroup analyses based on age, sex and rating of professional training were performed. Stressors at work were evaluated by priority and frequency of appearance.

Results

Data of 153 physical therapists was analysed. Low levels of job strain were reported. Novice physical therapists showed high levels of workplace commitment and general health, and low levels of turnover. Moderate ratings were recorded for job satisfaction and symptoms of burnout. Inadequate compensation for work, high caseload, time pressure and physical stress were the most common stressors mentioned. Therapists who rated their professional training as positive reported lower levels of job strain. No significant differences between women and men or between therapists of different age were found.

Conclusion

Although many workplace stressors are reported, novice physical therapists show low levels of job strain. Vocational training may be one important protective factor with regard to job strain.

Work-related musculoskeletal disorders among Egyptian physical therapists

Background

Physical therapists (PTs) are frequently exposed to work-related musculoskeletal disorders (WMSDs). There is limited evidence on the prevalence of these injuries and their potential risk factors in Egyptian PTs. This study aimed at estimating the prevalence of WMSDs among Egyptian PTs as well as potential risk factors and therapists’ coping strategies. Further, it investigated the association between WMSDs and socioeconomic factors.

Results

Three hundred eighty-five eligible participants completed a survey. The prevalence of WMSDs was 99.5%. The five top affected anatomic regions were lower back (69.1%), neck (65.7%), shoulder (47.7%), wrist/hand (39.1%), and upper back (37.0%). Therapists rated awkward positions and handling of heavy patients as the most common predisposing factors for sustaining injuries. Regarding coping strategies, seeking informal help from peers to treat injuries-related symptoms and changing the posture of therapists and patients while working were mostly used by PTs. Overall, female therapists had higher injury prevalence than males (Cramer’s V < 0.5, p ≤ 0.05); except for upper back (p > 0.05). Education and working in multiple facilities simultaneously (public and private clinics) correlated significantly to sustaining injuries in the upper back (V = 0.14, p = 0.049 and V = 0.178, p = 0.002, respectively) and neck (V = 0.16, p = .019 and V = 0.142, p = 0.020, respectively). WMSDs were not associated with therapists’ experience or specialty (p > 0.05).

Conclusion

WMSDs injuries in PTs are prevalent in Egypt, especially in females, therapists with lower academic education, and those working in multiple facilities simultaneously.

Workplace musculoskeletal problems in occupational therapy students

Background

Workplace musculoskeletal disorders are the leading cause of morbidity and disability in the Australian workforce. Over one in five occupational therapists report workplace musculoskeletal disorders, with almost half reporting workplace musculoskeletal symptoms. In other health professions, students and novice clinicians (≤5 years practice) experience greater risk but little is known about occupational therapy students.

Methods

In this cross-sectional study, a survey including the self-reported Standardised Nordic Musculoskeletal Questionnaire was administered to occupational therapy students post work-based training. Musculoskeletal problems were defined as aches, pains, numbness or discomfort. Questions explored body sites affected, prevalence, impact on activity, need for medical assistance, demographic and workplace information. Prevalence was reported using descriptive statistics. Factors associated with workplace musculoskeletal problems over the previous 12 months and last 7 days were examined using logistic regression modelling.

Results

Response rate was 53% (n = 211/397). One-third of respondents (33.6%, n = 71/211) reported a workplace musculoskeletal problem over 12 months. Nearly half (47.9%, n = 34/71) of these students reported a problem over the last 7 days. Neck was the most commonly affected area reported for musculoskeletal problems over the past 12 months (24.2%, n = 51/211) and shoulder areas affected over the past 7 days (10.9%, n = 23/211). Musculoskeletal problems preventing daily activities were reported most commonly from lower back problems over 12 months (23.9%, n = 17/71) and for shoulder problems over the last 7 days (21.9%, n = 7/32). Shoulders and knees were the most common body areas requiring medical attention. Previous musculoskeletal problems and female gender were associated with reported problems over 12 months and last 7 days (p < 0.05). Non-standard joint mobility (OR = 3.82, p = 0.002) and working in psychosocially focused caseloads (including mental health or case management) (OR = 3.04, p = 0.044) were also associated with reporting musculoskeletal problems over the last 7 days.

Conclusions

One in three occupational therapy students already experience workplace musculoskeletal problems impacting daily activities and requiring medical assistance prior to graduation. High prevalence of musculoskeletal problems in this study calls for educators and researchers to find sustainable strategies to address these problems, with particular consideration to the impact of previous disorders and working in psychosocially focused caseloads on musculoskeletal health.

Factors Associated with Musculoskeletal Disorders Among Female Readymade Garment Workers in Bangladesh: A Comparative Study Between OSH Compliant and Non-Compliant Factories

Purpose

Musculoskeletal Disorders (MSDs) are one of the most common occupational diseases responsible for work restriction and absenteeism. The purpose of the study was to compare the prevalence of MSDs between ready-made garment (RMG) factories that are compliant versus non-compliant with International Labor Organization (ILO) based Occupational Safety and Health (OSH) standards, and to identify other factors associated with a higher prevalence of MSDs.

Methods

A multicenter cross-sectional study was conducted among 410 randomly selected female workers (age: >18 years; ≥1 year of work experience) from 12 randomly selected RMG factories in the Dhaka district of Bangladesh from February to December 2019. Factories were stratified as OSH compliant or non-compliant. Data were collected using a structured questionnaire consist of socio-demographic, work-related factors, and Nordic Musculoskeletal Questionnaire (NMQ) for MSD assessment. Robust Poisson regression was used to investigate the association of MSDs with OSH compliance, socio-demographic and other work-related factors.

Results

Respondents’ mean age was 26.9 ± 5.9 years. A total of 235 (57%) of the workers reported musculoskeletal pain in at least one body part during the last month. Among the nine reported MSDs, the prevalence of lower back pain was highest (41%) followed by pain in the knees (33%). Multivariable analysis showed lower prevalence of any MSD among workers in OSH compliant factories [aPR = 0.43, 95% CI: 0.31–0.58], and workers with regular working hours (8 hrs/day) [aPR = 0.79, 95% CI: 0.62–1.00]. The risk of developing any MSD was significantly higher for age group 25–30 years [aPR = 1.16, 95% CI: 1.01–1.33] and age group ≥31 years [aPR = 1.21, 95% CI: 1.04–1.1.39].

Conclusion

The study found a high burden of musculoskeletal disorders among female RMG workers, especially those in non-OSH compliant factories that work long hours. Enforcement of minimum ILO-based OSH standards and introduction of low-cost interventions to improve working conditions in non-compliant factories would help sustain the pace of development in this sector in Bangladesh, and ensure the health of the women who work there.

Mechanical properties of a thoracic spine mannequin with variable stiffness control

OBJECTIVE

To test the posterior-to-anterior stiffness (PAS) of a new thoracic spine training simulator under different conditions of "fixation."

METHODS

We constructed a thoracic spine model using plastic bones and ribs mounted in a wooden box, with skin and soft tissue simulated by layers of silicone and foam. The spine segment could be stiffened with tension applied to cords running through the vertebrae and ribs. We tested PAS at 2 tension levels using a custom-built device to apply repetitive loads at the T6 spinous process (SP) and over adjacent soft tissue (TP) while measuring load and displacement. Stiffness was the slope of the force-displacement curve from 55 to 75 N.

RESULTS

Stiffness in the unconstrained (zero tension) condition over the SP averaged 11.98 N/mm and 6.72 N/mm over the TP. With tension applied, SP stiffness increased to 14.56 N/mm, and TP decreased to 6.15 N/mm.

CONCLUSION

Thoracic model compliance was similar to that reported for humans. The tension control system increased stiffness by 21.3% only over the SP. Stiffness over the TP was dominated by the lower stiffness of the thicker foam layer and did not change. The mannequin with these properties may be suitable for use in manual training of adjusting or PAS testing skills.

Association of working hours, job position, and BMI with work-related musculoskeletal disorders among the physiotherapists of Gujarat—an observational study

Background

Physiotherapists are prone to develop work-related musculoskeletal disorders (WMSDs). Region wise distribution and frequency of work disturbance have been studied in physiotherapists but exploration of the probable association of working hours, job position, and body mass index (BMI) with WMSDs is not adequately done in the Gujarat, India. Hence, the present study was undertaken to investigate these aspects among the physiotherapists of Gujarat.

Results

An online cross-sectional survey including 322 physiotherapists was conducted and the data was collected after gaining informed electronic consent. Present study showed no significant co-relation between job position (0.602), weekly working hours (0.930), and BMI (0.589) with WMSDs prevalence. The 1-year work disturbance and 1-week musculoskeletal difficulties were found to be due to low back-related complaints (35.09%, 33.85%).

Conclusion

It is inferred that high prevalence of WMSDs in physiotherapists may be due to one of various factors including job position, working hours, and BMI but they are not significantly correlated with WMSDs.

Frequency of examination and perceived contribution of factors relating to work-related musculoskeletal disorders of physiotherapists

Objective. Literature confirms that many physiotherapists suffer from work-related musculoskeletal disorders (WMSDs), but studies mention different, complementary and contradictory findings regarding risk factors. This scoping review aimed at revealing the most frequently examined and contributory WMSD factors mentioned in recent studies about physiotherapists. Methods. Based on specific inclusion/exclusion and appraisal criteria, 11 studies published between 2012 and 2018 were included in the analysis. The factors recorded per publication were grouped into 18 categories, the frequency of their appearance across the sources was counted and the median ranks of their relative reported contribution were calculated. Results. Excessive workload was found to be the most contributory factor, followed by the application of manual orthopaedic techniques. However, demanding and repetitive manual tasks were the most common factors investigated in the publications reviewed. A medium-strength correlation was found between the frequency of examination and reported contribution of factors but with a noticeable range of the confidence interval possibly due to the diversity of the approaches in the studies reviewed. Conclusions. The findings indicate a relative discordance between the level of contribution of each factor to the development of WMSDs and the types of factors most frequently addressed by studies.

Influence of Risk Perception on Task and Contextual Performance: A Case of Work-Related Musculoskeletal Disorders in Nurses

Assessing the risk perception of workers can be very informative in predicting their behavioral outcomes, including task and contextual performance. Yet, research to assess the effect of risk perception on task performance and contextual performance remains scarce. Thus, this study explored the effect of risk perception of work-related musculoskeletal disorders on task and contextual performance in nurses. This study further examined safety behavior as a mediator of these relationships. Using structural equation modeling, the researchers examined these relationships by employing a cross-sectional survey with a quantitative approach. The data was collected via questionnaires from 382 nurses who work in three major hospitals in Accra Metropolis, Ghana. The results showed that nurses' risk perception positively influenced their task and contextual performance, and that safety behavior partially mediated the effects of risk perception on task and contextual performance. This study offers a theoretical framework and empirical evidence for the concept of risk perception and its association with safety behavior, task, and contextual performance. To the best of our knowledge, this is the first study to assess the relationships that exist among these variables. Thus, future studies are needed to verify the causality of the relationships.

Evaluation of the Cervical Physiotherapeutic Treatment Needs, Work Ergonomics, and Necessity for Physical Activity Among Students of Dentistry at a Medical University. A Pilot Study

INTRODUCTION

A lot of general dental practitioners suffer from job-related health problems. They are more prone to numerous different physical and psycho-emotional triggers that aggravate their working conditions.

THE AIM

The aim of the study was to evaluate cervical physiotherapeutic treatment needs, daily ergonomic habits and the necessity for physical activity among students of dentistry at a medical university.

MATERIALS AND METHODS

112 generally healthy dentistry students (73 women, 39 men) were enrolled for the study. The age range was 20-32, with an average of 22.88 ± 2.7. The study included subjects in their second to fifth year of studies. The survey was conducted with respect to the questionnaires about possible physiotherapeutic treatments, physical activities, imaging tests and diagnoses as well as statements regarding the respondents' knowledge and ergonomics habits. To estimate the association between the risk factor and neck disability as well as chronic pain, the Neck Disability Index, Perceived Stress Scale and the Graded Chronic Pain Scale were additionally applied.

RESULTS

35.71% of dentistry students had undergo physiotherapy in the preceding year. 26.79% of the respondents declared that they underwent rehabilitation on a regular basis. The most common reasons for treatment were complaints of the cervical (7.14%), lumbar (3.57%), and thoracic spine (1.79%) as well as a combination of these symptoms. 6.25% of the subjects had started rehabilitation due to muscle relaxation. 34.82% of the study participants did not do any physical activity. Females exercised more often than males (p = 0.02; 1-β = 0.65). Therapeutic exercises contributed to the improvement of well-being of 56% of students. 64.29% of the respondents chose a sitting position during pre-clinical and clinical classes and 26.79% of the subjects worked in sitting and standing postures.

CONCLUSION

26.79% of dentistry students required periodic therapeutic rehabilitation. 34.82% of the respondents were advised to implement systematic physical activity. Due to professional conditions, dental students are exposed to an early cervical spine disorders. The main factor influencing an early onset of such dysfunctions is increased stress level. An average level of pro-health awareness may be the reason for elevated cost of rehabilitation among this group of patients.

Design and evaluation of a simple and affordable transfer assistive device for wheelchair users in the context of developing country

PURPOSE

The present study aimed at designing a simple, affordable, yet safe transfer assistive device (TAD) for lower limb impaired individuals in the context of a developing country.

METHODS

The preliminary study carried out, comprising a pilot survey with the involvement of stakeholder's views to design and develop the proposed device that had a unique feature. To evaluate the present TAD in terms of user's comfort of use and level of physical strain, subjects including 19 healthy students serving as "patients" have participated in a laboratory-simulated setting. Data was collected based on user's physiologic effort and rate of perceived exertion using Heart rate monitoring device (Polar RS 400 heart taster) and Borg's scale, respectively.

RESULTS

The data were analysed statistically and revealed that the regression equation for predicting the RPE from HR showed 31.3% of the variance in RPE was predictable from the level of HR. The ANOVA significance also indicates the model is statistically significant with (p < 0.013). Similarly, the estimated strain level has computed in terms of %HRR, and the physical strain averaged over the subjects who performed the task (n = 19) was expressed in terms of (mean ± SD) %HRR were (16.21±7.64%) which was a relatively smaller strain level as compared to the previous research report.

CONCLUSION

The present device found a potentially affordable solution for reducing fatigue and strain level that might develop during unassisted transfer. Similarly, the unique feature of the armpit support has contributed to dynamic contact force reduction and as double safety support.Implications for rehabilitationThe use of transfer assistive device is associated with increased patient satisfaction and privacy of usersImproved patient adherence and cooperation with caregivers in rehabilitation center.Encourages the rehabilitation settings to use transfer assistive devices instead of manual handling there by increase the recovery period.

Work-related musculoskeletal disorders in physical therapists attributable to manual therapy

Background: Use of manual therapy (MT) is a risk factor for the development of work-related musculoskeletal disorders (WRMDs) in physical therapists (PTs) although the current evidence is limited on this topic.Objectives: The purpose of this study was to understand the type, association, and prevalence of WRMDs among practitioners of MT, explore relationships between MT and WRMD, and determine impacts of WRMDs on PTs.Design: Cross-sectional survey design.Methods: A web-based survey was distributed through the Academy of Orthopaedic Physical Therapy of the American Physical Therapy Association. The survey gathered information on the respondents' professional profiles, any WRMDs sustained, and how those injuries affected their professional and personal lives.Results: Overall, 38.5% of PT respondents using MT reported having sustained an MT attributable WRMD. Female respondents reported a greater rate of MT attributable injuries. Although exposure risk is cumulative, novice practitioners are also injured.Limitations: Generalizability of these results may be limited because of the sample size and specific population responding.Conclusion: Over one-third of PT survey respondents reported WRMDs attributable to MT. The results indicated WRMDs may begin early in one's career and tend to accumulate over years of practice. MT educational programming at all levels warrants emphasis on practitioner safety.

Musculoskeletal Complaints in Occupational Therapists Compared to the General Population: A Cross-Sectional Study in Germany

Occupational therapists (OTs) are exposed to physical factors at work, which can lead to an increased risk of musculoskeletal disorders. Most studies examining musculoskeletal complaints in OT report that the neck, shoulders, and lower back are most often afflicted. The aim of the present study was to examine the impact of work as an OT (focusing on specific work tasks) on specific musculoskeletal complaints compared to the general working population. A cross-sectional study involving a self-administered standardized questionnaire was conducted from January until October 2015 in Germany. In OT and the comparison group, the highest 12-month prevalence of musculoskeletal disorders were observed for the lower back, the neck, and the shoulders. In contrast, elevated prevalence ratios (PR) were found for OT in the thumbs (PR = 2.7; 95% CI = 1.9-3.8), the wrists (PR = 1.4; 95% CI = 1.1-1.8), and the elbows (PR = 1.5; 95% CI = 1.0-2.2). OTs were particularly exposed to high exertion hand activity and several stressful postures at work. In conclusion, OTs seem to be at risk of developing work-related musculoskeletal complaints in the thumbs, wrists, and elbows. Preventive measures should help to reduce the exposures caused by highly repetitive and forceful hand activities.

Dose-response association between multi-site musculoskeletal pain and work ability in physical therapists: a cross-sectional study

PURPOSE

Multi-site musculoskeletal pain (MP) is common among health care professionals and is considered a threat to work ability and thereby a long and healthy working life. However, literature is scarce regarding these associations among physical therapists (PTs). This study aims to quantify the prevalence of local and multi-site MP among PTs, to investigate the associations between pain intensity and number of pain sites, respectively, with the level of work ability.

METHODS

We conducted a survey among 1006 PTs about pain the previous month in different body areas and work ability. Work ability was measured using the Work Ability Index (WAI) including its seven categories. The odds of having lower level of work ability as a function of pain intensity (0-10) and multi-site pain were determined using binary logistic regression controlled for relevant confounders.

RESULTS

The neck (36.3%) and the low back (32.3%) were the most commonly affected body areas. Furthermore, a dose-response relationship was observed between the number of pain sites and lower work ability (trend test, p < 0.001). With low pain intensity as reference, a moderate to strong association existed for lower levels of work ability in PTs who reported pain intensity of > 5 in one to two body regions (OR 2.14, 95% CI 1.27-3.60). This association was stronger when participants reported pain in three to four sites (OR 4.02, 95% CI 2.36-6.82) and even stronger when pain was experienced in five or more sites (OR 6.13, 95% CI 3.31-11.38).

CONCLUSIONS

Multi-site MP is strongly associated-in a dose-response fashion-with lower levels of work ability among PTs.

Pressure Distribution Across the Handle of an Instrument-Assisted Soft Tissue Mobilization Tool

Instrument-assisted soft tissue mobilization (IASTM) tools are used during rehabilitative care for treatment of injuries to muscles, tendons, and ligaments. Many studies have quantified treatment application forces between tools and the patient. However, the effect of force on the clinician has not been studied even though research shows that clinicians experience discomfort and fatigue during treatment. This work presents a method to accurately measure the pressure profile between the IASTM tool handle and hand of the clinician. Flexible pressure indicating film was used to measure the pressure magnitude and distribution on the hand. These tests were performed at varying treatment application forces between 15 and 60 N, normal to the treatment surface. The tests were repeated, and forces were compared between 3D-printed designs. The pressure profile on the user was explored by changing aspects of the handle design. Results are analyzed and discussed as an effect of changing handle dimensions. As the diameter of the handle increased, the pressure magnitude decreased while the pressure distribution across the hand increased. Changing the contour of the handle further decreased the magnitude and increased the distribution. This procedure is not specific to the chosen tool and can be repeated for other tools.

Assessing the physiological strain of physical therapists according to work experience: A cross-sectional study

OBJECTIVES

This cross-sectional study aimed to assess the physiological response of physical therapists to compare the physiological workload within three groups of varying work experience and their comparative physiological responses during a 15-min recovery period.

METHODS

Thirty therapists participated in the present study. They were divided into three groups with varying levels of work experience based on the number of years they had been in active employment: 1) Early Career (EC) group = 2-6 years); 2) Mid-Career (MC) group = 7-11 years), and 3) Late career (LC) group = over 11 years). Each group included 10 subjects comprised of both males and females. To conduct the measurements, each therapist treated one hemiplegic patient for 20 min using a passive range of motion protocol and then rested for 15 min. The maximum voluntary contraction on trapezius and deltoid muscles were tested using electromyography before and after treatment. During treatment, the muscle workload, muscle fatigue, and cardiovascular load were measured. The perceived workload was assessed using a subjective workload index (SWI) questionnaire following treatment.

RESULTS

The three work experience groups of physical therapists performed a similar workload. The SWI corresponded well with physiological measurement. The muscle capacity after treatment of the EC group was significantly lower than that of the MC group (p < 0.05). Notably, the right deltoid of the LC group was significantly lower than that of the MC group.

CONCLUSIONS

The physical therapists worked with a moderate, objectified workload. A 15-min rest period brought the cardiovascular load below 30% and lowered fatigue in the right deltoids. This result may indicate a musculoskeletal disorder warning signal for the physical therapists.

Comparison of two methods of bed-to/from-wheelchair transfer in patients with hemiparetic stroke

OBJECTIVES

The ability to transfer between surfaces is essential for wheelchair users' independence. We hypothesized that transfer of hemiparetic stroke patients would be improved by using surfaces at the same height with no gap or obstacle between them.

METHODS

A cross-sectional study was conducted to compare the difficulty of two transfer methods as a pilot study. Thirteen hemiparetic stroke patients were transferred from a platform table to a chair (wheelchair or flat chair) and from the chair to the table using the regular and lateral transfer methods. Functional Independence Measure (FIM) transfer score in both transfer methods and Stroke Impairment Assessment Set (SIAS) score were measured.

RESULTS

The FIM transfer score significantly increased in the lateral transfer condition compared with the regular transfer condition, indicating that the former method reduced the transfer difficulty, regardless of the SIAS scores.

CONCLUSIONS

The transfer difficulty of patients with hemiparetic stroke decreases when using the lateral transfer method. The lateral transfer method is easy, potentially helping prevent care-related injuries among caregivers.

Manual therapy for work-related wrist pain in a manual physical therapist

Introduction: The wrist is a common site for work-related musculoskeletal disorders (WMSD) among physical therapists (PTs), often due to manual therapy. There are limited data on management of wrist injury in PTs. The purpose of this case is to describe the management of a PT with wrist pain.Case Description: The patient was a 28-year-old female with a 6-month history of right ulnar-sided wrist pain, aggravated by performing thoracic/lumbar posterior to anterior (PA) glides. The patient reported 7/10 on the Numeric Pain Rating Scale and 6.5/10 on the Patient-Specific Functional Scale (PSFS). Symptoms were reproduced at the lunotriquetral joint.Outcomes: The patient was seen for two visits. Following anterior to posterior non-thrust mobilization at the triquetrum on lunate, the patient improved inability to perform thoracic/lumbar PA glides. The patient was educated on manual therapy modifications, isometrics, and self-mobilization. At 2-month follow-up, the patient reported 0/10 pain, scored 10/10 on the PSFS, and +7 on the Global Rating of Change.Discussion: This case demonstrates the successful use of education, manual therapy, and exercise in the management of a PT with a wrist-related WMSD. Future research should focus on the prevention/treatment of wrist-related WMSDs in PTs who perform manual therapy.

Wrist and hand pain in orthopaedic physical therapists: A mixed-methods study

BACKGROUND

Orthopaedic physical therapists (PTs) who perform manual therapy are at high risk for wrist and hand pain. Studies that examine the magnitude, scope and causes of wrist and hand pain are needed so that prevention programs can be developed.

OBJECTIVES

The objective of this study was to determine the magnitude, scope, and impact of wrist and hand pain in orthopaedic PTs and to identify potential strategies for prevention.

DESIGN

This was a sequential, mixed methods study including quantitative and qualitative components.

METHODS

The quantitative phase consisted of an online survey sent to members of the Academy of Orthopaedic Physical Therapy. The qualitative phase consisted of focus groups with Orthopaedic PTs who had wrist and hand pain.

RESULTS

The survey included 962 PTs and the focus groups included 10 PTs. The one-year prevalence of wrist and hand pain was 75%. Increasing age, decreasing experience, female gender, performing more manual therapy and working more than 40 h per week were associated with an increased risk of moderate to severe wrist and hand pain. Soft-tissue mobilization was the most frequently cited causative factor. The most commonly mentioned strategy for prevention was altering body mechanics and technique. Focus group participants highlighted the importance of managing expectations for manual therapy by patients.

CONCLUSIONS

Formal injury prevention programs for PT students and PTs are urgently needed. These programs should focus on improving body mechanics and technique, attention to workload, careful selection of manual techniques, and managing expectations for manual therapy.

Prevalence, Profile, and Response to Work-Related Musculoskeletal Disorders among Egyptian Physiotherapists

BACKGROUND:

Despite that physiotherapists (PTs) are supposed to have adequate knowledge of musculoskeletal disorders and the different prevention strategies, they are at high risk of developing work-related musculoskeletal disorders (WRMDs).

AIM:

This study aimed to investigate the prevalence, profile, predictors, and response to WRMDs among Egyptian PTs.

METHODS:

A self-administrated questionnaire was distributed either manually or via e-mail to 564 PTs with at least two years of working experience. Questions elicited information about the personal and occupational history of the respondents in addition to the experience of WRMDs in the past two years.

RESULTS:

Four hundred and fourteen respondents (82.6%) reported WRMDs within the last two years, with the lower back as the most common area affected (68.8%). More than half the PTs (54.8%) who sustained a WRMD reported that their injury took place in a private setting. Significant predictors for WRMDs were age (AOR = 0.78; 95% CI = 0.66, 0.91) and number of years of experience in physiotherapy practice (AOR = 1.26; 95% CI = 1.07, 1.49). In response to the injury, about 73.9% of the respondents stated that they did not officially report their injury and 55.8% of them reported losing a half day or more from their work.

CONCLUSION:

The prevalence of WRMDs among Egyptian physiotherapists is high. Despite socioeconomic and cultural differences between Egypt and other countries, our study findings were consistent with the published reports. Further studies are needed to explore the cultural and psychosocial risk factors of WRMDs.

Claim Costs, Musculoskeletal Health, and Work Exposure in Physical Therapists, Occupational Therapists, Physical Therapist Assistants, and Occupational Therapist Assistants: A Comparison Among Long-Term Care Jobs

BACKGROUND

Patient/resident-handling tasks are physically demanding and associated with musculoskeletal disorders (MSDs) among nursing personnel. The routine performance of such tasks by physical therapists and occupational therapists during treatment can cause similar problems.

OBJECTIVE

This study characterized the magnitude of MSDs and the risk factors for MSDs in physical therapists, occupational therapists, physical therapist assistants, and occupational therapist assistants (collectively called "therapy personnel" for this study) and compared them with those of other nursing home workers, especially nursing staff.

DESIGN

This was a cross-sectional study.

METHODS

Workers' compensation claim (WCC) data from 1 year of experience in a long-term care company were used to compute claim rates by body region, nature, and cause of injury, and the costs per case and per full-time-equivalent employee. Data regarding musculoskeletal symptoms, use of patient/resident-lifting equipment, and perceived physical and psychological job demands were obtained from a concurrent cross-sectional survey of workers from 24 long-term care facilities.

RESULTS

About 80% of the WCCs were related to musculoskeletal incidents in nursing aides and therapy personnel. WCC costs paid per case for therapy personnel were more than twice those for nursing staff for both ergonomic and resident-handling incidents. Prevalence of low back pain in therapy personnel was the same as in nursing aides (48%) but involved more chronic, milder pain. About half of therapy personnel reported "never" or "rarely" using patient/resident-lifting equipment. Therapy personnel, nursing aides, and housekeeping/dietary/maintenance personnel reported the highest physical job demands.

LIMITATIONS

Causal inference cannot be determined due to the cross-sectional nature of the survey data. Study findings are relevant only to therapy work in long-term care settings because exposures vary in other health care settings (hospitals, outpatient, and others).

CONCLUSIONS

MSD prevalence and claim costs in therapy personnel are high enough to deserve more attention. The low use of patient/resident-lifting equipment in therapy could increase the risk for MSDs. Future studies with comprehensive ergonomic analysis of therapist tasks and recommendations to reduce injuries are warranted.

Work-Related Upper Limb Symptoms in Hand-Intensive Health Care Occupations: A Cross-Sectional Study With a Health and Safety Perspective

BACKGROUND

Research with physical therapists reveals high rates of work-related musculoskeletal injuries, especially low back pain, with early career onset. Less focus has been given to upper limb disorders (ULDs) in these professionals, who frequently perform repetitive arm/hand and precision finger motions during work.

OBJECTIVE

The objective was to estimate prevalence of body-site-specific upper limb (UL) symptoms and diagnosed ULDs in Irish chartered physical therapists, physiotherapists, and athletic therapists, with adjustment for leisure time injury, and document first onset of specific UL symptoms.

DESIGN

The design was a cross-sectional survey (N = 347) using random sampling (physiotherapists in private practice), proportionate cluster sampling (hospital-based physiotherapists), and all-population sampling (physical therapists and athletic therapists).

METHODS

The methods used were a postal questionnaire with annual, current, and incapacitating UL symptoms (neck, shoulders, elbows, wrists, fingers, thumbs) (Nordic Questionnaire); symptom onset; diagnosed UL disorders; and sociodemographics; prevalence with 95% CIs, and adjusted prevalence (general linear modeling).

RESULTS

Adjusted annual prevalence of UL symptoms in at least 1 body site was 78.1% (95% CI = 71.4-82.2), and of incapacitating symptoms was 21.0% (95% CI = 16.4-27.0). Shoulder (53.2%, 95% CI = 47.9-58.7), neck (49.4%, 95% CI = 44.2-55.0), and thumbs (46.1%, 95% CI = 40.7-51.5) were mostly affected. Hospital-based therapists had a significantly higher prevalence of incapacitating symptoms compared with others (35.7% vs 23.3%). Respondents totaling 28.2% had at least 1 lifetime diagnosis of ULD, most commonly shoulder tendonitis (12.5%, 95% CI = 8.4-15.3) and overuse syndrome (11.8%, 95% CI = 8.4-15.3). First onset was mostly after 5 years working as a therapist; however, this differed by anatomical site.

LIMITATIONS

A cross-sectional study design limited interpretation of symptoms as work-related causes.

CONCLUSIONS

The high prevalence of ULD and symptoms warrants attention from occupational health and safety personnel. Training in injury prevention and risk assessment should be provided during education and as part of continuing education.
