Comparative reliability of different instruments used to measure the severity of musculoskeletal disorders in office workers

The Impact of Therapeutic Exercises on the Quality of Life and Shoulder Range of Motion in Women After a Mastectomy, an RCT

Breast cancer ranks highest in incidence and mortality among females and second among both genders. Lebanon has the second highest rate of breast cancer worldwide for those 35-39 years old and the highest for those 40-49. Mastectomy often results in deceased shoulder and arm mobility and decreased quality of life. The objective of this study was to assess the effect of an educational program of therapeutic exercises on the quality of life and functional ability in women after a mastectomy. Sixty women undergoing a mastectomy were randomly assigned to either an intervention or control group. The intervention group received extensive pre-surgery education as well as training on therapeutic exercises. Follow-up phone calls to the intervention group were made to ensure that the exercises were being done. Both groups were visited at home at two and four weeks to obtain the outcome variables. The Breast Cancer Patient Version was used to assess quality of life, and the "Goniometer" was used to assess the range of motion of the affected shoulder. At two and four weeks after surgery, women in the intervention group had significant improvements in their shoulder range of motion: flexion, extension, and abduction were significantly different between the control and intervention group at p = 0.04-0.00. For quality of life, physical, psychological, psychological, social, and spiritual well-being were significantly higher for the intervention group at both two and four weeks after surgery, p < 0.001. In a middle-income country, one-to-one education provided by a nurse, which included demonstrations, back demonstrations, and weekly phone calls had a positive impact on women's shoulder range of motion and quality of life.

Effect Of Mental Imagery And Physical Exercise On Musculoskeletal Pain And Quality Of Life Among Office Workers: A Commentary

Background — Musculoskeletal pain is one of the most common problem among office workers. The main reason is related to the long time spent sitting and the associated lack of physical activity. Musculoskeletal pain can affect not only their work-related performance, but also their personal performance and quality of life. Research has mainly focused on the effects of physical activity in managing musculoskeletal pain in office workers, while research is sparse pertaining to the possible role of mental imagery on reducing musculoskeletal pain in office workers. While mental imagery has only a minor effect on pain modulation in healthy individuals, its effect appears to be more pronounced in those with chronic pain. Aim — This commentary attempts to present beneficial mental imagery techniques that can be used solely or in combination with physical exercise in an office-based setting to improve musculoskeletal pain to enhance work performance and quality of life among office workers.

Association of musculoskeletal pain with poor sleep quality in public school teachers

BACKGROUND

Teachers perform repetitive movements all day, which can cause pain in body regions. This article analyzes the association of pain with sleep quality in this population.

OBJECTIVE

The objective of the study was to analyze the relationship of musculoskeletal pain and sleep quality in teachers from public schools.

METHODS

The sample consisted of 242 teachers, selected in a random process. Musculoskeletal pain and sleep quality were evaluated by using a questionnaire. The association between sleep quality and musculoskeletal pain was evaluated using the chi-square test. The magnitude of the associations was verified by Binary Logistic Regression, adjusted by sex, age, BMI, and socioeconomic status.

RESULTS

Teachers with poor sleep quality presented higher body mass index (BMI) values when compared to teachers with good sleep quality (27.9 vs 26.0, p = 0.012). Teachers with poor sleep quality were approximately twice as likely to report thoracic pain (OR = 2.16[95% CI = 1.12-4.16]), wrist pain (OR = 3.28[95% CI = 1.18-9.07]), low back pain (OR = 3.09[95% CI = 1.29-7.41]), and ankle/foot pain (OR = 2.83[95% CI = 1.32-6.08]).

CONCLUSIONS

Teachers with poor sleep quality were approximately twice as likely to present pain in several body parts. Our findings revealed that poor sleep quality was significantly associated with musculoskeletal pain in Brazilian teachers of public schools, regardless of confounding factors.

Home-based fundamental approach to alleviate low back pain using myofascial release, stretching, and spinal musculature strengthening during the COVID-19 pandemic

BACKGROUND

The COVID-19 pandemic has caused global adoption of stay-at-home mandates in an effort to curb viral spread. This lockdown has had the unintended consequence of decreasing physical activity, and incidence of low back pain (LBP) is likely to rise as sedentary behavior increases.

OBJECTIVE

In this article, we aim to provide a fundamental, novel approach to alleviate LBP including desk worker associated LBP exacerbated during the COVID-19 pandemic.

METHODS

Individuals can alleviate their LBP through a simplistic, self-therapeutic approach: myofascial release and stretching of key musculature involved in LBP following a simple technique and associated time domain, as well as a 360-degree strengthening of the muscles surrounding the lower back. Additional muscular strength will support the lower back and lend resilience to aid in the mitigation of pain caused by poor work-related postural positions.

RESULTS

We demonstrate several exercises and movements aimed at alleviating LBP. Additionally, we provide a summary graphic which facilitates ease of use of the exercise plan and represents a novel methodology for simple distribution of evidence-based pain reduction strategies.

CONCLUSIOS

Through mitigation of sedentary behavior and adoption of the techniques described herein, LBP can be decreased and, in some cases, cured.

Vacuum myofascial therapy device for non-specific neck pain. A single blind randomized clinical trial

OBJECTIVES

This study aimed to investigate the efficacy of a vacuum myofascial therapy device (VT) for improving pressure pain thresholds (PPTs), range of motion (ROM), neck pain-related disability, pain, and quality of life in patients with non-specific neck pain.

METHODS

A randomized controlled trial in which thirty-eight participants with non-specific neck pain (NP) were randomly assigned to either an experimental (VT) or a comparison physical therapy program (PTP) group. The VT group (n = 19) received five sessions of treatment with a vacuum myofascial therapy device while the PTP group (n = 19) received five sessions of massage, ultrasound therapy (US), and transcutaneous electric nerve stimulation (TENS) over two weeks. The outcome measures were the numerical pain rating scale (NPRS), range of motion, quality of life (SF-12), neck disability Index (NDI), and PPTs at the end of treatment and at one-month follow-up.

RESULTS

Although both groups experienced improvements in pain, neck disability, range of motion, and pressure pain, these only were statistically significant in the VT group. At one-month follow-up, the VT group still showed improvements in pain, neck disability, and range of motion.

DISCUSSION

Vacuum myofascial therapy applied with a device offers similar results to other vacuum-based techniques such as cupping therapy. Moreover, in this device the parameters are digitally controlled, which allows for the precise reproduction of treatment.

Postural risk associated with Wooden Steel Chairs and Stackable Arm Chairs in a low-income country

BACKGROUND

Wooden Steel Chairs (WSCs) and Stackable Arm Chairs (SACs) are widely used in tertiary institutions of learning in low income countries. No local studies seem to have investigated the postural risk associated with the concerned chair type.

OBJECTIVE

This study aimed to evaluate the postural risk associated with WSCs and SACs. It also determined the anatomical distribution of musculoskeletal complaints among users of the chair types.

METHODS

Purposive sampling was used to select 100 desktop computer users (23.25±1.6 years) of which 50% consistently used a computer laboratory with WSCs and the other half used one with SACs. The Rapid Upper Limb Assessment (RULA) method was used to evaluate the sitting posture of users of both chair types. Musculoskeletal complaints were investigated using the Nordic musculoskeletal questionnaire.

RESULTS

Analyses showed significantly higher (p < 0.05) mean RULA scores for the right side of the body for users of WSCs (6.08±0.85) compared to users of SACs (5.26±1.23). Statistically significant differences (p < 0.05) were found on the prevalence of lower back pain between users of WSCs and SACs. Among all study participants, 72% reported musculoskeletal pain at one or more body parts in the previous 12 months. Self-reported complaints pertained to the neck (24%), lower back (19%), shoulders (16%), elbow (8%), upper back (8%) and wrist (4%).

CONCLUSION

WSCs seem to pose a higher postural risk for lower back pain than SACs. Ergonomics interventions and exercise training programmes may be useful to address the poor working posture and musculoskeletal complaints.

Prevalence, source and severity of work-related injuries among "foreign" construction workers in a large Malaysian organisation: a cross-sectional study

Malaysian construction sector is regarded as critical in the field of health because of the high rates of accidents and fatalities. This research aimed to determine the prevalence, sources and severity of injuries and its association with commitment to safety among foreign construction workers. A cross-sectional study was conducted among 323 foreign construction workers from six construction projects of a large organization in Malaysia, using a simple random sampling method. Data was collected using a structured questionnaire to assess work-related injuries and safety commitment. The collected data was analysed by SPSS 22.0 using descriptive statistics and χ² test. The prevalence of work-related injuries in a one year period was 22.6%, where most of the injuries were of moderate severity (39.7%) and falls from heights represented the main source (31.5%). The majority of the foreign construction workers had perceived between moderate and high safety commitment, which was significantly associated with work-related injuries. The results also showed a significant association of work-related injuries with the company's interest in Safety and Health, Safety and Health training, and safety equipment. Thus, the implementation of new procedures and providing relevant trainings and safety equipment; will lead to a decrease in injury rates in construction sites.

Development of new hard hat dimensions using user-centered design approach among oil palm harvesters

BACKGROUND

Hard hats are among the personal protective equipment (PPE) used in many industries to reduce the impact of any falling object on the skull and also to prevent head and brain injuries. However, the practice of wearing a safety helmet during working hours is still low. This is due to the physical discomfort perceived by safety helmet users.

OBJECTIVE

Given the unpopularity of the current hard hat, the general perception of workers concerning its use and its measurements are the determining factors in the development of a new hard hat.

METHOD

A cross-sectional study was conducted in which 132 male oil palm harvesters between 19 and 60 years of age were selected from among the employees of the same oil palm harvesting company. A set of questionnaires was developed to collect their socio-demographic information as well as their perceptions of comfort and the prevalence of head injury. In addition, a set of measuring instruments, including Martin's anthropometry set, was used for head measurement and data collection in respect of the current hard hat. In this research, six respondents were randomly selected to attend an interview session for qualitative assessment.RESULTSBased on the questionnaires, the unpopularity in the use of the hard hat was largely influenced by factors related to poor design, in general, and, specifically, poor ventilation (64%), load (67% ), and physical discomfort (42% ). The measurements of the anthropometric parameters and the dimensions of the hard hat also showed a significant mismatch.

CONCLUSION

The unpopularity of the current hard hat among oil palm harvesters stemmed from the discomfort from wearing, which showed that the development of a new hard hat could lead to better usage and the greater likelihood of wearing a hard hat throughout the working day.
