Physical and psychosocial work demands associated with pain and disability among skilled male Arab waiters.

BACKGROUND: Physical and psychosocial demands (e.g., serving, cleaning, fulfilling orders) can lead to work-related musculoskeletal pain (WRMSP). OBJECTIVE: To assess the prevalence of WRMSP in the upper quadrant and lower back among skilled male Arab waiters; to evaluate the disability related to WRMSP; to evaluate the association between work demands and WRMSP with related disability. METHODS: 100 skilled male Arab waiters working full-time, aged 18-60, participated in the cross-sectional study. Participants completed basic demographics and working conditions; the NDI; QuickDASH; the OswestryQ; workload, burnout, and job satisfaction at work; the adjusted NordicQ; and the TaskQ, compiled especially for this study. RESULTS: A 12-month pain prevalence, pain frequency, and work avoidance were high: neck- 42%, 60.5%, 89.5%; shoulders -53%, 78.2%, 94.4%; elbows- 46%, 78.6%, 83.3%; lower back- 45%, 44%, 78.7%, respectively. Pain prevalence in at least one site was 83%. The OswestryQ, QuickDASH, and NDI revealed mild-moderate pain and disability (14.85/50, 25.54/75, 13.74/50, respectively). Burnout score was positively associated with OswestryQ, QuickDASH, and NDI. Job satisfaction was negatively associated with 12 months of pain in the lower back, hands, arms, shoulders, and hands (NordicQ). TaskQ was positively associated with OswestryQ. CONCLUSION: Male Arab waiters who work in physically and psychologically challenging conditions report high levels of WRMSP with a high frequency and related work avoidance. Many of them must keep their jobs as they are their families' primary or sole providers. It is possible that they are trying to prevent more severe disabilities in the future by ensuring temporary rest and pain prevention.

Disparities in occupational health services: an international comparative study.

BACKGROUND: Occupational Health Services (OHS) are comprehensive, multidisciplinary services supplied by various trained workers, including occupational physicians (OP), whose specialty is focused on workers' health. AIMS: Our study questions are whether the OP/worker ratio may reflect the scope and availability of OHS. METHODS: This comparative study, conducted on globally different OHS, was based on literature analysis of peer-reviewed articles published in journals covering topics of occupational medicine and public health that addressed parameters on the type and scope of OHS provision. RESULTS: We described the number of OP/worker ratio, and the correlation to economic parameters (Gross domestic product-GDP, health expenditure, Gini Index-GI) by country. We found that among countries with a GDP per capita higher than US$30,000, only three (US, South Korea and Israel) had a very low OP/worker ratio (about 1:50,000 compared to 1:5,000 in other countries). Looking at all the countries together, there was a statistically significant negative correlation between health expenditure percentage of GDP per capita and OP/worker ratio (rs = -0.54, p = 0.01) and a significant positive correlation between GI and OP/worker ratio (rs = 0.47, p = 0.04). CONCLUSIONS: The lesser the percentage of health expenditure of GDP and the subsequent greater general inequality as reflected by the GI, the lower the OP/worker ratio. The data collected in our comparative study show that the OP/worker ratio is a parameter both easy to define and obtain which best represents the status and disparity of OHS in each country.

Optimal bed height for passive manual tasks.

PURPOSE: To determine bed height adjustment for maintaining neutral lumbar position as a function of anthropometric dimensions. MATERIALS AND METHODS: 80 physical therapy students performed passive shoulder flexion and straight leg raising tasks on standard versus the adjustable bed. The lumbar angle was measured at the start and finish of tasks. The rate of perceived exertion was measured immediately after each task. The most comfortable bed height in relation to some anatomical landmarks was measured. RESULTS: Mean bed height for shoulder flexion tasks was significantly higher than for straight leg raising. The mean adjusted bed heights for both tasks were significantly higher and with less exertion felt by the participants, compared to the standard bed height (0.715 m). The third knuckle of the hand and the radial styloid process of the wrist were established as the most valuable anthropometric landmarks for bed height adjustment. CONCLUSIONS: The above landmarks are recommended to maintain a neutral lumbar position while adjusting bed heights for manual tasks. Each manual task requires adjustment of the bed height. Further studies are needed to confirm our results.

Work-related musculoskeletal disorders and injuries among emergency medical technicians and paramedics: A comprehensive narrative review.

The aim of this article was to review the current knowledge relating to work-related musculoskeletal disorders (WRMDs) and non-fatal injuries in emergency medical technicians and paramedics (EMTs-Ps). A literature search was conducted in PubMed, Google Scholar, and Clinical Key. The annual prevalence of back pain ranged from 30% to 66%, and back injuries and contusions from 4% to 43%. Falls, slips, trips, and overexertion while lifting or carrying patients or instruments ranged from 10% to 56%, with overexertion being the most common injury. Risk factors were predominantly lifting, working in awkward postures, loading patients into the ambulance, and cardiopulmonary resuscitation procedures. Lack of job satisfaction and social support was associated with WRMDs and injuries. EMTs-Ps had the highest rate of worker compensation claim rates compared to other healthcare professionals. Positive ergonomic intervention results included electrically powered stretchers, backboard wheeler, descent control system, and the transfer sling.

Osteophytes on the zygapophyseal (facet) joints of the cervical spine (C3-C7): A skeletal study.

Previous studies have reported that osteophytes in the cervical vertebrae may cause immobility, neck stiffness, osteoarthritis, headaches, nerve entrapment syndromes, and compression of the vertebral artery. Our objective was to explore the osteophytes' expression on zygapophyseal joints C3-C7. This is a cross-sectional observational skeletal study. The study sample comprised 273 human skeletons of both sexes, aged 20-93, housed at the Natural History Museum, OH, USA. A grading system assessed the presence and severity of osteophytosis on the zygapophyseal joints. The chi-square test (SPSS 25.0) examined the association between osteophytes and demographic factors. The level of significance (α) was set at .05. The highest prevalence of osteophytes was found on C5 vertebra, the lowest on C7. On vertebrae C3, C4, C6, the rate of moderate and severe osteophytes found on the superior and inferior facets were comparable. Moderate and severe degrees of osteophytes were observed more frequently on the superior facets, whereas, on vertebra C7, osteophytes were found on the inferior facet joints. Osteophytes' prevalence was significantly higher in the elderly compared to the younger population. Osteophytes in the C3-C7 zygapophyseal joints are age-dependent. No significant sex and ethnic differences were observed. Vertebra C5 was most prone to develop osteophytes, most probably due to its location in the cervical lordotic peak, C5 in the superior ZF; C7 in the inferior ZF are significant (p = .05). The zygapophyseal joints of C7 were least frequent overall, yet, the C7 inferior facets had significantly more moderate-severe osteophytes compared to other cervical vertebrae.

Upper Quadrant Pain and Disability Associated with a Cross-Sectional Area of Deep and Superficial Neck Muscles: A Computed Tomography Study.

STUDY DESIGN: An analytical cross-sectional computed tomography (CT) study. OBJECTIVE: To investigate the association of the cross-sectional area (CSA) and density of neck muscles (sternocleidomastoid, upper trapezius, levator scapulae, anterior scalene, longus coli, longus capitis) with upper quadrant pain and disability. SUMMARY OF BACKGROUND DATA: Neck pain, a common condition, causes substantial disability to individuals. The deep cervical flexor muscles are impaired in persons with neck pain. These muscles play a greater role in maintaining stable head postures, whereas, superficial muscles are responsible for peak exertions and reinforcing spinal stability at terminal head postures. METHODS: Two hundred thirty consecutive individuals suffering from neck pain were referred to CT scans; 124/230 complied with the inclusion and exclusion criteria. Subjects were interviewed and the measurements of the CSA and muscle density were extracted from the scans. RESULTS: Muscles associated with quick disability of the arms, shoulders, and hand questionnaire (QDASH) were the lateral posterior group (LPG) CSA C3-C4 on the right side (beta = -0.31, P = 0.029); the sternocleidomastoid (SCM) CSA C3-C4 on the left side (beta = 0.29, P = 0.031); the LPG CSA C3-C4 on the left side (beta = -0.49, P = 0.000); the LCM CSA C5-C6 on the right side (beta = -0.19, P = 0.049); the LPG CSA C5-C6 on the right side (beta = -0.36, P = 0.012); and the LPG CSA C5-C6 on the left side (beta = -0.42, P = 0.002). Further analyses with radiculopathy acting as an augmenting/enhancing variable (moderator), showed an increase in the model strength (r2 = 0.25) with a stronger prediction of pain and disability. Muscle measurements did not predict neck disability index (NDI) scores. CONCLUSION: By using an accurate measuring tool, we found an association of the deep and superficial neck muscles' CSA with upper extremities' pain and disability. When performing manual work, a special load is placed on the shoulders and neck muscles. Future research should focus on examining the effectiveness of exercise-type intervention programs to strengthen the deep neck and upper extremities' muscles in order to prevent muscle fatigue.Level of Evidence: 2.

Developing a grading scale for the evaluation of degenerative changes in uncovertebral (Luschka) joints.

The study aimed to develop a grading scale for evaluating degenerative changes in uncovertebral joints (UVJs) found on computed tomography (CT) scans, and assess the intra- and inter-rater reliability of this scale. The study included 50 subjects (average age 55.12 ± 13.76 years) referred for CT examinations due to cervical complaints. Three researchers developed a reading protocol using a semiquantitative grading scale of UVJ degenerative changes. CTs were read and reread several times to refine the protocol. Subsequently, the reader read and reread 20 CTs (C3-C7 bilateral, altogether 200 UVJs) 2 weeks apart in order to assess the intra-rater reliability. The second reader, after the training, read the same 20 CTs (yet, C4-C6 bilateral, altogether 120 UVJs) in order to assess the inter-rater reliability. The additional 30 CTs were evaluated to analyze the prevalence and associations between the studied parameters. The final grading scale included joint space narrowing, osteophyte, subchondral sclerosis, subchondral cyst, hypertrophy, cortical erosion, and vacuum phenomenon. The intra-rater agreement ranged from very good in joint space narrowing (k = 0.757), osteophyte grade (k = 0.748), subchondral cyst (k = 0.716), hypertrophy (k = 0.728), vacuum phenomenon (k = 0.712) to good (k = 0.544) in subchondral sclerosis, and fair in cortical erosion (k = 0.36). For the overall UVJ degeneration grade, the intra-rater agreement was very good (k = 0.616) and the inter-rater reliability was good (k = 0.468). 77.6% of the evaluated UVJs exhibited some degenerative changes. Our grading scale is the first to evaluate UVJs presenting good-very good intra-rater and inter-rater reliability which can be utilized in further clinical studies and assess degenerative changes in UVJs.

Effect of Guided Imagery on Pain and Health-Related Quality of Life in Musculoskeletal Medicine: a Comprehensive Narrative Review.

PURPOSE OF REVIEW: Guided imagery (GI) is a non-pharmacological method used to reduce pain, stress, and anxiety. No comprehensive review has yet investigated the application of GI in musculoskeletal medicine, its various types, and potential mechanisms. The aim of this comprehensive narrative review was to examine the types of GI used in musculoskeletal medicine and GI effect on pain and health-related quality of life. RECENT FINDINGS: A comprehensive narrative review of the English language scientific literature. PubMed, Google Scholar, ProQuest, and PEDro databases were searched from inception until August 2020 using keywords related to GI, musculoskeletal disorders, pain, and health-related quality of life. The search results generated 133 articles. After a critical analysis, 12 publications were included in this review. GI characteristics and protocols varied significantly between studies. Based on the reviewed studies, we advocate GI as a safe, non-invasive technique that can assist in managing pain, depression, stress, fatigue, anxiety, reducing medication use, improving general well-being, wellness, and quality of life in patients with musculoskeletal disorders. We recommend further investigations of GI mechanisms.

Hebrew adaptation and validation of a clinical-quantitative method of low back pain evaluation (the BADIX).

BACKGROUND: The BackAche Disability Index (BADIX) is a 2-section test: (a) the BackAche Index encompassing 5 active back movements, evaluated on a 4-point Likert-type rating scale; (b) the morning Back Stiffness Score, choosing the most fitting statement out of 6, upon awakening. OBJECTIVE: To perform a cross-cultural adaptation and evaluate the reliability and validity of the Hebrew version of BADIX. METHODS: Translation/retranslation of the English version of the BADIX was conducted, and the cross-cultural adaptation process performed. The Hebrew version BADIX was evaluated at two meetings, two weeks apart, in 51 female nurses (40 reported back pain and 11 reported no back problems). The Rolland Morris Disability Questionnaire (RMQ) and The Modified Oswestry Low Back Pain Disability Questionnaire (MODQ) were also evaluated. RESULTS: The mean age of the subjects was 45.34±11.11 years. Internal consistency calculated by the Cronbach's α coefficient was very high (α>0.9). A high degree of test-retest reliability was found, with an intraclass correlation coefficient (ICC) 95% CI) of 0.933 (0.839 - 0.973), and r=0.908. Concurrent validity of the BADIX domains with the RMQ and MODQ was found statistically significant and high (ρ=0.688, RMQ, and ρ=0.674, MODQ). CONCLUSIONS: The adapted and modified Hebrew version of the BADIX is reliable and measures the pain and mobility outcome of physical impairment and morning backache stiffness. It can be employed, in addition to self-reported outcome measures, by clinicians and researchers in quantitatively evaluating the clinical status and progression of patients with lower back pain in Hebrew-speaking populations.

The correlation between the ACR questionnaire and fitness for work of fibromyalgia patients.

OBJECTIVES: Fibromyalgia (FM) is a central pain syndrome characterised by widespread pain, fatigue, unrefreshing sleep, memory impairment and cognitive changes, predominantly in women, and is a cause for disability and frequent sick leave. So far, no assessment has been made of the use of the American College of Rheumatology (ACR) 2010 questionnaire in the fitness for work (FFW) assessment of FM patients. To assess the correlation between the severity of FM as measured by the ACR questionnaire and other parameters and FFW. METHODS: We conducted a retrospective cross-sectional study involving women with FM who had their FFW assessed at an occupational health clinic between 2014-2018. The ACR questionnaire was completed during the medical assessment. RESULTS: We examined 60 files of women, mean age 48.8 years. Absolute loss of working capacity (ALWC) was calculated in relation to a standard 8-hour workday, while relative loss of working capacity (RLWC) was based on the patient's actual appointment percentage before the examination. The average ALWC determined by the occupational physicians was 59% ± 33%. Age group correlated significantly with ALWC (correlation coefficient = 0.03, p<0.05). The Part 2b symptoms (0-41) also correlated significantly with ALWC (mean ± SD 21.8±5.6, correlation coefficient = 0.23, p<0.05). Medical treatment correlated significantly with RLWC (correlation coefficient = 0.02, p<0.05). The rate of disability was high compared to what was reported in other studies. The correlation between different parts of the ACR questionnaire and disability demonstrated that symptom severity is a predictor of loss of working capacity. CONCLUSIONS: When performing a FFW assessment of FM patients, physicians may use the ACR questionnaire, since FFW correlates with its score. We assume that patients who experience more pain visit their physicians more often and consume more analgesics.

Occupational influences on Spondylolysis and Spondylolisthesis in a cohort of 18-year-old male military conscripts.

BACKGROUND: The reported prevalence of spondylolysis (SL) in the adult population is 6-7%. Data concerning adolescent-onset spondylolisthesis (SLS) and the impact of certain activities on it is scarce. We examined the risk of clinical progression of SL and SLS as a function of primary severity and occupational strain among military recruits. METHODS: Based on the Israel defense Force (IDF) central human resources database, we identified 1521 18-year-old males inducted to the IDF with SL/SLS between the late nineteen nineties and early two-thousands. We followed changes in the SL/SLS status during the 3 years of obligatory military service. Disease severity was classified as Cat2: radiological findings of SL without clinical findings; Cat3: painful SL or asymptomatic grade 1 SLS; Cat4: grade 1 SLS with pain; Cat5: Grade 2 SLS. The soldiers were subdivided into the following occupational categories: administrative, combat, maintenance, and driving. The purpose was to compare the progression rates in different medical categories and job assignments. RESULTS: There were 162 recruits in Cat2, 961 in Cat3, and 398 recruits in Cat4. The overall progression rate to Cat5 (grade 2 SLS) was 1.02%. Significant progression rates were seen amongst administrative soldiers with a relatively higher risk of progression from Cat4 (painful-grade-1 SLS: 2.2%) vs. Cat3 (asymptomatic SLS: 0.5%, relative risk = 4.7, p < 0.02). Other occupational categories did not exhibit significant progression rates. CONCLUSION: Progression of SL/SLS was highest in Cat4, i.e. for recruits already diagnosed with painful SLS (i.e. with a more severe baseline disorder). Progression did not correlate with military occupation. We recommend further follow-up studies that include, aside from progression rates, incidence rates of newly diagnosed grade 2 SL during military service.

Sliding Sheet Use in Nursing Practice: An Intervention Study.

Background: Previous studies have discovered that the utilization of sliding sheets in patient care is a valuable technique for repositioning bedridden patients compared with traditional cotton sheets or carriers. Our aim was to examine the effects of sliding sheet usage on work-related musculoskeletal disorders and disability, perceived workload, burnout, and job satisfaction, among nurses and nursing assistants. Method: This repeated measurement study included 41 female nurses and nursing assistants from three internal medicine departments who provided direct patient care. Participants completed an eight-part questionnaire (demographics, Neck Disability Index, Quick Disability of the Arms, Shoulder and Hand Questionnaire, Modified Oswestry Low Back Pain Disability Questionnaire, BackAche Disability Index workload, burnout, and job satisfaction) 4 times during the study period: 3 months prior to the intervention, on the first day of the intervention, and 3 and 6 months after commencement of the intervention. Findings: After 3 and 6 months of sliding sheet usage, pain and disability decreased in the neck (p < .001); arms, shoulders, hands (p = .041); and lower back (p < .001), with an increase in job satisfaction (p < .001). Discussion/Application to Practice: The findings of our study indicate a clear influence of reducing work-related musculoskeletal pain and disability while increasing job satisfaction when sliding sheets are introduced into nursing practice. Occupational health nurses in health care should consider this type of low-cost intervention as a method for reducing musculoskeletal injury among direct patient care providers.

Osteophytes in the Cervical Vertebral Bodies (C3-C7)-Demographical Perspectives.

Vertebral osteophytes are an age-dependent manifestation of degenerative changes in the spine. We aimed to determine the prevalence and severity of cervical osteophytosis in a large study population. To do so, we developed a grading system for osteophytosis, enabling the assessment of their presence and severity in the cervical spine, and applied it to the analysis of dried cervical vertebral bodies (C3-C7) from 273 individuals. Statistical analyses were carried out per motion segment, while testing for the effect of age, sex, and ethnicity. The highest prevalence of osteophytes was found in motion segment C5/C6 (48.2%), followed by C4/C5 (44.1%), and last C6/C7 and C3/C4 (40.5%). Severe osteophytes are most commonly seen in motion segment C5/C6. In all motion segments, the inferior discal surface of the upper vertebra manifests more osteophytes than the superior discal surface of the lower one. Osteophytes prevalence is sex-dependent only in the upper cervical vertebrae (C3-C4), and age- and ethnicity-dependent for all vertebrae. Anat Rec, 302:226-231, 2019. © 2018 Wiley Periodicals, Inc.

The torg ratio of C3-C7 in African Americans and European Americans: A skeletal study.

The ratio between the sagittal diameter of the spinal canal and the sagittal diameter of the vertebral body, known as the "Torg ratio", is often used to test for spinal canal narrowing. Here, we investigate this ratio in a large population, consisting of two ethnicities, both sexes and three age groups. Measurements were taken on the dry cervical verterbrae (C3-C7) of 277 individuals using a digital apparatus allowing for the recording of 3D coordinates of a set of landmarks on the vertebral body. Vertebral body and vertebral foramen lengths were compared across the different subgroups. Vertebral body and vertebral foramen lengths differ significantly between males and females and between African Americans and European Americans. With age, the vertebral body length increases while the foramen length does not undergo significant changes. These anatomical differences are reflected in differences in the Torg ratio calculated for the different subgroups. In conclusion, our findings suggest that a hard cutoff on the Torg ratio used to define a pathological narrowing of the cervical spine should be adapted to the population the patients come from.

Repositioning a passive patient in bed: Choosing an ergonomically advantageous assistive device.

Repositioning of passive patients in bed creates health risks to the nursing personnel. Therefore, appropriate assistive devices should be used. Our aim was to find the optimal assistive device for reducing musculoskeletal load while moving a passive patient in bed. Torso kinematic inputs evaluated by the Lumbar Motion Monitor (LMM) and perceived load (Borg scale) were measured in female nurses performing 27 patient transfers [represented by a mannequin weighing 55 (12 nurses), 65 (24 nurses) and 75 kg (12 nurses) in bed] using a regular sheet, a sliding sheet and a carrier. The lowest rates of perceived exertion were found when the sliding sheet and/or carrier were used, for all tasks (p ≤ 0.009). According to the predicted risk for Low Back Disorder (LBD) based on the LMM inputs, negligible differences between assistive devices were found. In a 75 kg mannequin, the participants were able to perform all tasks only by using a sliding sheet. Utilizing sliding sheets is an advantageous technique in comparison to traditional cotton sheets and even carriers.

Demographic aspects in cervical vertebral bodies' size and shape (C3-C7): a skeletal study.

BACKGROUND CONTEXT: This cross-sectional study was conducted on the skeletal remains of individuals of known sex, age, and ethnic origin. The vertebral bodies of levels C3-C7 were measured and analyzed. Whereas many studies were performed on the size and shape of the vertebral bodies in the thoracic and lumbar spines, few have focused on the cervical vertebral bodies. Thus, there is insufficient data in the literature on the anatomy of the cervical spine, especially based on large study populations. PURPOSE: To establish a large database on cervical vertebral bodies' size and shape and analyze their association with demographic parameters. STUDY DESIGN: The population studied was composed of 277 individuals, adult males and females of African American (AA) and European American (EA) origin. The skeletal remains are housed at the Hamman-Todd Osteological collection (Cleveland Museum of Natural History, Cleveland, OH). METHODS: A 3-D digitizer was used to measure the size and shape of the C3-C7 vertebral bodies. Descriptive statistics were carried out for all measurements. t Test and one-way analysis of variance were performed to assess differences in vertebral bodies' size and shape between different demographical groups (by age, sex, and ethnicity). RESULTS: The vertebral bodies and foramina are significantly wider, more elongated, and higher in males compared to females. AA females and males manifest significantly greater vertebral bodies (width and length) in the upper and midcervical region (vertebrae C3-C5) than EA females and males. Nevertheless, the heights of the C3 and C4 vertebral bodies are significantly smaller among the AA population, regardless of sex. The vertebral foramina's width does not differ significantly between the two ethnic groups, independent of sex, whereas they tend to be elongated in the EA group (significant for C3, C5, C7). For most vertebrae, no significant differences were found in the superior facets' length between AA and EA males and females. Cervical vertebral bodies become wider and more elongated with age, although the changes in the latter dimension are much more pronounced than in the former. Notably, the body shape of the cervical vertebrae changes gradually from a more round shape (C3 length/width index=0.84) to a more oval one (C7 length/width index =0.65). This is due to the fact that the width dimensions increase by almost 40% from C3 to C7, whereas the length dimensions increase only by approximately 10%. Furthermore, there is a significant reduction in body height with age in C3-C6. In contrast, no significant changes in vertebral foramen size with age were found. CONCLUSIONS: The cervical vertebral bodies' shape and size are sex-dependent phenomena, that is, in all parameters studied, the dimensions were greater in males than in females. For the midcervical level, there is a difference in body shape between individuals of different ethnic origins. The cervical vertebral bodies also exhibit considerable size and shape changes with age, that is, they become more elongated (oval shaped), wider, and shorter. In contrast, vertebral foramen size is age independent.

Work-related musculoskeletal disorders among physical therapists: A comprehensive narrative review.

Healthcare workers, especially those with direct patient contact are amongst professions with the highest rate of workrelated musculoskeletal disorders (WMSDs), physical therapists (PTs) being one of them. Our objective was to review current knowledge relating to the prevalence, risk factors and prevention of WMSDs among PTs. Pubmed, Google Scholar and PEDro databases were searched for terms relating to WMSDs in PTs from inception to 2015. The prevalence of WMSDs among PTs was high, with lifetime prevalence reported as 55-91%, and 12-month prevalence ranges 40-91.3%, and the lower back as the most frequently affected, with estimates of a lifetime prevalence ranging 26-79.6%, and a 12-month prevalence ranging 22-73.1%, followed most often by the neck, upper back and shoulders. The major risk factors for workrelated low back pain (LBP) were: lifting, transferring, repetitive movements, awkward and static postures, physical load, treating a large number of patients in a single day and working while injured. Low back pain seems to be age- and genderrelated with a higher prevalence in females, younger PTs and PTs working in rehabilitation settings. Physical therapists, as a consequence of work-related LBP, may seek treatment, modify their daily living and leisure (lifestyle) activities, use aids and equipment or change their specialty area either within the profession or by leaving it. Skills and knowledge as to correct body mechanics do not prevent work-related injuries. Mechanical aids used for a patient transfer should be adopted by PTs and new strategies should be developed to reduce their WMSDs without compromising the quality of treatment. Int J Occup Med Environ Health 2016;29(5):735-747.

The impact of patient's weight on post-stroke rehabilitation.

Purpose To evaluate the influence of patient's weight on rehabilitation outcomes in first-event stroke patients. Design Retrospective, observational comparative study. 102 first-time stroke male and female patients admitted to the 52-bed neurology rehabilitation department in a rehabilitation hospital were included in the study. Body mass index (BMI), Functional Independence Measure (FIM) on admission and at discharge, as well as the delta-FIM (FIM on admission - FIM at discharge) were evaluated. The Kruskal-Wallis test was used to compare the FIM and the NIHSS scores between BMI groups (normal, overweight, moderate and severe obesity). Results A statistically significant negative correlation (rho = -0.20, p = 0.049) was found between FIM change and BMI, that remained significant after adjustments for age, sex and hospitalisation days. No difference was found between groups in FIM or NIHSS change between BMI groups. Conclusions In sub-acute post-stroke patients undergoing rehabilitation in rehabilitation hospital, BMI was negatively associated with the improvement of functional parameters. Patients' BMI should be taken into consideration when predicting rehabilitation outcome for stroke patients. Further investigations are needed to identify the functional parameters affected by the patients' BMI. Implications for Rehabilitation In sub-acute post-stroke patients undergoing rehabilitation in rehabilitation hospital, BMI was negatively associated with the improvement of functional parameters. Patients' BMI should be taken into consideration when predicting rehabilitation outcome for stroke patients. New rehabilitation strategies should be designed to improve the functional outcomes of rehabilitation of obese patients.

Effect of kinesio tape application on hemiplegic shoulder pain and motor ability: a pilot study.

The aim of our single-group pre-post design pilot study was to evaluate the short-term effect of kinesio taping (KT) application on pain and motor ability of hemiplegic shoulder pain (HSP) patients. Eleven poststroke patients with HSP hospitalized in the Department of Neurology C, Loewenstein Rehabilitation Hospital, Raanana, Israel, received a KT application in addition to their usual rehabilitation protocol. KT, consisting of one to three strips according to a predefined algorithm, was applied to the painful shoulder region. A 10 cm Visual Analog Scale of shoulder pain at rest and at arm movement, active and passive pain-free abduction range of motion, Box & Blocks, and Fugl-Meyer upper extremity motor assessment were performed before treatment and 24 h after wearing the KT. After applying the KT, there was no significant change in any variables. Short-term KT application, used in our study, produced no change in shoulder pain, range of motion, or ability of upper limb in HSP patients. Additional studies should evaluate the effect of long-term application and different types of KT applications on HSP.

Prevention of Nurses' Work-Related Musculoskeletal Disorders Resulting From Repositioning Patients in Bed: Comprehensive Narrative Review.

Repositioning patients in bed to promote comfort and prevent impairments caused by continuously lying in a prone position is a task frequently performed by nurses and nursing assistants. Repositioning is a high-risk activity, frequently causing occupational injuries. These occupational injuries are attributed to excessive physical demands on nurses due to patients' weight and awkward nurse postures. During repositioning, risk of injury can be lowered by reducing friction between the patient and the bed. Hence, certain friction-reducing devices have been developed to reduce the manual force required to move patients. Nevertheless, further research is needed to evaluate the potential effectiveness of these devices. Therefore, the aim of this review was to present current research about the risk factors, prevention strategies, and assistive devices that could reduce work-related musculoskeletal disorders caused by repositioning patients in bed.
