    A cross sectional study was conducted among tea plantation workers in Cameron Highlands from July to December 2006
    to study the prevalence of low back pain and factors associated with it. One hundred and six tea plantation field workers participated
    in the study. Data was collected using self-administered questionnaire. Time motion studies were also conducted for 3 different job
    categories. The prevalence of back pain experienced throughout their work in the plantation was 81.1% and the prevalence of low
    back pain experienced in the past 12 months was 64.2%. Feeling the need to work as fast as possible was a significant predictor of low
    back pain and increased the risk by 3.5 times, therefore it is suggested that both the management and workers give serious attention
    to this particular aspect to reduce the incidence of low back pain.

    Being a rare clinical entity, discal cyst presents indistinguishably from other causes of lower back pain and radiculopathy. It is an extremely rare pathology with unclear pathogenesis, indeterminate natural history with no consensus on the ideal management of the condition. We report a rare case of discal cyst in a patient who presented to our centre with localised low back pain and subsequently left sided radicular pain. With the aid of MRI and with clear surgical indication we proceeded with endoscopic removal of the cyst and intraoperatively confirmed its origin from the adjacent disc. The patient had immediate relief of his symptoms and no postoperative complications. We recommend that endoscopic surgery can be an effective alternative to conventional open surgery for discal cyst of the lumbar spine.

    To determine the risk factors associated with complain of low back pain. A cross sectional study was done from June 2004 until August 2005. Seven hundred and sixty commercial vehicle drivers from 11 bus companies in central, northern and eastern regions in Malaysia participated in this study. Modified Nordic questionnaire was used to determine the prevalence of low back pain; Maestro human vibration meter was used to measure the personal R.M.S values of lateral, anterior-posterior and vertical axes. Modified Owas was used to assess the awkward posture of the driver torso namely, bending forward movement, leaning, sitting straight and twisting. Profile of Mood States (POMS) was used to evaluate the mood states of bus drivers with complain of low back pain. A high prevalence of low back pain (60.4%) among Malaysian commercial vehicle drivers was found. Logistic regression analysis controlling for age, income, education level and non occupational activities revealed that the following factors were related to low back pain: Tension-anxiety [1.080, 95% CI 1.041-1.121], depression dejection [1.047, 95% CI 1.023-1.072], anger-hostility [1.053, 95% CI 1.027-1.081], fatigue [1.132, 95% CI 1.089-1.177] and confusion [1.114, 95% CI 1.061-1.169] of POMS, length of employment [1.001, 95% CI 1.0-1.003], steering wheel adjustment [1.521, 95% CI 1.101-2.101], perception of exposing to vibration [1.943, 95% CI 1.389-2.719]. In conclusion, combinations of risks lead to high increase of low back pain complain among Malaysian bus drivers.

    The aim of this review was to systematically explore the underlying musculoskeletal biomechanical mechanisms of carrying and to describe its potential relationship with low back pain. This literature review was carried out using AMED, CINAHL, Compendex and MEDLINE electronic databases. Articles published from 2004 to 2012 were selected for consideration. Articles were considered if at least one measurement of kinetics, kinematics or other related musculoskeletal parameters related to biomechanics were included within the study. After combining the main keywords, 677 papers were identified. However, only 10 studies met all the inclusion criteria. Age, body mass index, gender and level of physical activity were identified as the factors that may influence the biomechanics of carrying activity. Carrying a loaded backpack was reported leading to posterior pelvic tilt, reduced lumbar lordosis, but increased cervical lordosis, thoracic kyphosis and trunk forward lean. Furthermore, while carrying bilaterally, lumbo-pelvic coordination was also reported to be more in-phase, as well as reduced coordination variability in transverse plane. Future studies investigating the biomechanics of a standardized carrying activity for clinical test are recommended.

    Work-related Musculoskeletal Disorders (WMSDs) are common occupational injuries among workers in the construction industry. Epidemiological studies indicated that WMSDs include neck pain, lower back pain, knee pain, leg fatigue as well as ankle and feet discomfort. The objectives of this study are to identify the WMSDs experienced by the workers during construction works and discuss the causes of those WMSDs. Subjective approach associated with modified Nordic Musculoskeletal Questionnaire (NMQ) was applied to identify the symptoms of WMSDs. A case study was conducted in several construction sites situated at the southern region of Peninsular Malaysia. During the study, 37 construction workers with different age and scope of works were interviewed to determine the WMSDs that they have experienced. Based on distributed questionnaire, almost all workers experienced pain in the region of lower back, upper back and biceps. These pains were contributed by manipulation of heavy load and high force exertion. Based on discussed causations, control measures via engineering controls method and administrative controls method were proposed to alleviate the risk of WMSDs among construction workers.

    Introduction Non-specific low back pain is one of the most common physical ailments
    affecting millions of people worldwide. This condition constitutes a
    significant public health problem and was listed as a prevalent health
    complaint in most societies. Even though there are many anecdotal claims
    for reflexology in the treatment of various conditions such as a migraine,
    arthritis and multiple sclerosis, but very little clinical evidence exists for
    reflexology on the management of low back pain per se. This study aims to
    evaluate the effects of foot reflexology therapy as an adjunctive treatment to
    the Malaysian low back pain standard care in relieving pain and promoting
    health-related quality of life among people with non-specific low back pain.
    Methods This is a parallel randomized controlled trial with pre and post-treatment
    study design. The study setting for the intervention located at Penawar
    Reflexology Center, Kuala Terengganu, Malaysia. A total of 100
    participants with non-specific low back pain will be allocated to one of two
    groups, using a randomization computer program of Research Randomizer.
    The control group will receive low back pain standard care, while the
    intervention group will receive standard care plus eight sessions of foot
    reflexology therapy. The pain intensity and health-related quality of life
    scores will be measured using Visual Analogue Scale and Euro-quality of
    life scale respectively in both groups. The study was approved by the
    Human Research Ethics Committee of University Sultan Zainal Abidin
    (UHREC/2016/2/011). The study protocol was registered at
    ClinicalTrials.gov, with the ID number of NCT02887430.
    Measurements Outcome measures will be undertaken at pre-intervention (week 1), postintervention
    (week 6) and follow-up (week 10).
    Conclusions This will be the first trial to compare the foot reflexology therapy with
    control group among people who medically diagnosed with non-specific low
    back pain in Malaysia. The result of this study will contribute to better
    management of this population, especially for Malaysia healthcare setting.

    BACKGROUND AND PURPOSE: Musculoskeletal disorders (MSDs) are alarmingly high among migrant workers in Malaysia. MSDs are the most prevalent occupational-related conditions in most parts of the world affecting function, productivity and overall health-related quality of life. Therefore, this study aims to determine the profile of Filipino migrant workers in Malaysia and their various musculoskeletal complaints.

    METHOD: This study utilized a quantitative, nonexperimental, cross-sectional research design. A total of 60 subjects were randomly selected after passing the study's sampling criteria. The Nordic Musculoskeletal Questionnaire (NMQ) was to used to determine common MSDs affecting the various regions in the body. The Demographic Pofile Sheet was provided to gather a subject's demographic characteristics.

    RESULTS: Filipino migrant workers mostly complain of pain in the low back area (60%) and shoulder pain (60%), followed by pain in the upper back (48.3%) and neck pain (45%) in the last 12 months. Household workers accounting for 73.3% of the subjects commonly complain of pain in the hips/thighs (78.9%), while workers in the service industry commonly complain of knee pain (39.1%).

    CONCLUSIONS: Results imply that Filipino migrant workers have a higher prevalence of shoulder and lower back pain in the last 12 months. Household workers are more susceptible to hip/thigh pain. Interventions focusing on ergonomics policy implementation, education on posture and lifting techniques and physical function is recommended. Further studies should consider the psychological and psychosocial aspects of migrant employment, which are known risk factors for MSDs.

    PURPOSE: The goal of this trial was to determine whether low-load blood flow restricted (BFR) exercise of appendicular muscles induces a cross-transfer of effect to the trunk extensor (TE) muscles, such that low-load TE exercise would enhance TE size and function to a greater extent than standard low-load exercise in people with recurrent low back pain (LBP). We also investigated the direct effects of BFR exercise in the appendicular muscles.

    METHODS: 32 adults with recurrent, non-specific LBP were randomized into two groups: Appendicular BFR Exercise (BFR Exercise) or Control Exercise (CON Exercise). All participants trained (2x/week) for 10-weeks, with a 12-week follow-up. Participants performed three sets of leg extension (LE), plantar flexion (PF), and elbow flexion (EF) exercises followed by low-load TE exercise without BFR. Outcome measures included MRI-derived muscle size (quadriceps and TE), strength (LE, PF, EF, and TE), and endurance (LE and TE).

    RESULTS: There was no evidence for a cross-transfer of effect to the trunk extensors. There was also no statistically significant enhancement of limb skeletal muscle size or function of BFR relative to CON Exercise at any time point; though, moderate effect sizes for BFR exercise were observed for enhanced muscle size and strength in the leg extensors.

    CONCLUSIONS: Low-load BFR exercise of the appendicular muscles did not result in a cross-transfer of effect to the TE musculature. There was also no significant benefit of low-load BFR exercise on the appendicular muscle size and function, suggesting no benefit from low-load BFR exercise in adults with recurrent, non-specific LBP.This is an open access article distributed under the Creative Commons Attribution License 4.0 (CCBY), which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited.

    Chronic low back pain is a common, disabling and costly health problem. The treatment of chronic low back is difficult and is often ineffective. For treatment to be effective the cause of the pain has to be established but unfortunately in 80% to 95% of the patients the cause cannot be determined despite the existence of modern imaging techniques. A pathoanatomical diagnosis which fits into a classical disease model where successful treatment can be carried out, can only be made in 5% to 7% of the patients. The back pain in the rest of the patients where no pathoanatomical diagnosis can be made is often labelled, unscientifically, as chronic low back pain. Despite the existence of sophisticated imaging techniques and a plethora of diagnostic test the source of pain in patients with nonspecific back pain cannot be established. There exist no causal relationship between imaging findings of degenerated disc, lumbar facet arthritis, spondylosis, spondylolysis and spondylolisthesis, to the pain in these patients. Surgical treatment of non-specific back pain where no pathoanatomical diagnosis has been established is bound to fail. Therefore the outcome of spinal fusion in these patients can be no better than nonsurgical treatment. Spinal fusion is a major surgery which can be associated with significant morbidity and occasionally with mortality. Yet there is rapid rise in the rates of spinal fusion. There is a growing tension between ethics and conflicts of interest for surgeons. The spine, unfortunately, has been labelled as a profit centre and there are allegations of conflicts of interest in the relationship of doctors with the multi-billion dollar spinal devices industry. The devices industry has a significant influence on not only research publications in peer review journals but also on decisions made by doctors which can have a detrimental effect on the welfare of the patient.

    Ewing's sarcoma is a rare tumor first discovered by James Ewing in 1921. It is more common in bone or skeletal component compared to soft tissue or extraosseous Ewing's sarcoma. Among soft tissue Ewing’s, spinal cord involvement is rarer with only nine cases reported. We report a case of nine-year-old Malay girl who presented with low back pain for two months following a fall with progressive neurological deficits of bilateral lower limb. Magnetic resonance imaging was suggestive of a well-defined margin of intradural extramedullary tumor. With nerve sheath tumor in mind, surgical excision with laminectomy L2-S1 was performed. Intraoperative finding was an extradural mass from L3-L5 with extension to bilateral neuroforamen. Histopathology report defined a round cell tumour of Ewing’s sarcoma from the mass.

    Bertolotti's syndrome must be considered as a differential diagnosis for lower back pain in young people. Treatment, whether conservative or operative, is still debatable. In this paper, we report a case of a 20-year-old girl presenting with lower back pain for 8 years. We administered injection with local anaesthetic and steroid injections within the pseudo-articulation; however, the pain was relieved for 3 weeks. Surgical excision of the pseudo-articulation successfully treated her back pain and the sciatica.

    The prevalence of neuropathic low back pain differs in different ethnic populations. The aims of the study are to determine its frequency and associations in a multi-ethnic cohort of Asian low back pain patients. This was a cross-sectional study of low back patients seen at the University of Malaya Medical Centre, Kuala Lumpur, Malaysia. Neuropathic low back pain patients were identified using the painDETECT questionnaire and compared with non-neuropathic (unclear or nociceptive) low back pain patients, in terms of socio-demographic and clinical factors, pain severity (numerical pain rating scale, NPRS), disability (Roland Morris Disability Questionnaire, RMDQ), as well as anxiety and depression (Hospital Anxiety and Depression Scale, HADS). Of 210 patients, 26 (12.4%) have neuropathic low back pain. Neuropathic pain is associated with non-Chinese ethnicity, higher body mass index and pain radiation below the knee. Patients with neuropathic pain have significantly higher NPRS and RMDQ scores, and there are more subjects with anxiety on HADS. However, there are no differences between the groups in age, gender, pain duration or underlying diagnosis of low back pain. The prevalence of neuropathic low back pain in a multi-ethnic Malaysian cohort is lower than previously reported in other populations with possible differences between ethnic groups. It is associated with greater pain severity, disability and anxiety.

    Objective: A cross-sectional study was conducted to determine and evaluate the effects of schoolbag load on electromyography (EMG) activity of the erector spinae muscle.
    Methods: Eighty-four primary schoolchildren were selected from two national medium primary schools in Seri Kembangan, 42 from Primary Two (P2) and 42 from Primary Five (PS), aged 8 and 11 respectively. Data were collected through interviews, anthropometries measurements, the weight of schoolbag load and surface electromyography (SEMG) of the erector spinae using Muscle Tester ME3000f'®. SurfaceAg-AgCl electrodes were used to measure: unloaded standing and walking, and loaded standing and walking.
    Results: The study revealed that the erector spinae was found to be more efficient in loaded standing probably due to other trunk muscle co-activity compared to unloaded standing (p<0.05). However, the erector spinae was less efficient when loads were carried on the back while walking, compared to unloaded walking. When the schoolbag was carried over both shoulders, forces generated by the erector spinae were reduced and resulted in a more efficient use of the erector spinae compared to other asymmetrical carrying methods (p<0.05).
    Conclusions: Bending slightly forward when carrying schoolbag was found to reduce the forces generated by the erector spinae compared to normal sagittal posture (p<0.05), however no significant difference was found between the different frontal postures. A significant inverse relationship (p<0.01) between the weight of schoolbag load and the average electromyography (AEMG), showed that the signifieance of the erector spinae muscle was reduced when a heavier schoolbag load was carried, owing to other trunk muscles co-activity. The study also revealed that apart from age of schoolchildren, family history of back pain, exposure to environmental tobacco smoke (ETS), weight of the schoolbag and method of carrying schoolbag also play important role as risk factors for back pain.

    Introductions: Call center has been defined as a working environment in which uses telephone and computer for the purpose of marketing and manage communication with prospect clients or existing clients (Rocha, Glina, Morinho and Nakasato, 2005; Sprigg, Smith and Jackson, 2003).
    Methodology: The study was conducted via observation of working condition and face to face interview with call center operators. Measurement of anthropometrics was also conducted.
    Results: Ergonomics issues found at call center were inappropriate work condition and workstation which lead to awkward sitting posture (sitting with forward leaning posture, raised shoulder, feet not supported on floor). Besides that organizational policy which required high job demand and subsequently lead to prolonged sitting and static posture (very minimal posture changes). Combination all these factors lead to musculoskeletal symptoms and the operators reported of having neck, shoulder, upper back and lower back pain compared to other body parts.
    Conclusion: The management should embark on organization wide ergonomics management program and should review the current policy and create safe and healthy working environment by providing suitable workstation for the operators in order to prevent musculoskeletal.

    The low back is usually associated with the lumbar spine which supports the entire weight of the upper body and significantly, is vital to the body mobility. Injury to the surrounding soft tissues can cause mild to debilitating symptoms due to muscle strain and ligament sprain. The causes of injury to the lower back are probably due to sudden twisting movement, poor posture position at work and manual handling of heavy objects or with twisting or bending movements while lifting. An Ergonomic Risk Assessment was carried out on a dental laboratory worker who complained of unresolved low back ache after a year on treatment and follow up at the outpatient department of a health clinic. From the various investigative methods used, it was found that the worker in question was placed in a situation that will over time encourage her to develop musculoskeletal disease. Our recommendations for change include immediate awareness and training in ergonomic principles of work and to report all cases so that appropriate action can be taken, reassess the workstation and environment of work, job enrichment, and creating a conducive environment for work. Once the changes have been implemented, a review will be necessary in three months time.

    Backache is a common health problem associated with non ergonomic working environment. A cross sectional study amongst the rubber tappers was conducted to determine the prevalence of low back pain and ergonomic factors related to it. The respondents were 116 male rubber tappers from Felda scheme in the state of Pahang who were selected by random sampling. The result showed prevalence of low back pain was 60.3% and has significant association with history of backache (p<0.05). Rubber tappers were 6 times more higher to develop low back pain if they had history of backache (Odd Ratio =6.24, 95% CI). There were no significant association between socio-demographic factors and low back pain. Ergonomic factors such as bending during tapping, respondents’ height and duration of the tapping showed no significant association with low back pain. Further study should be done in ergonomic aspect to explore the problem.

    BACKGROUND: Musculoskeletal pain is common among teachers. Work-related psychosocial factors are found to be associated with the development of musculoskeletal pain, however psychological distress may also play an important role.

    OBJECTIVES: To assess the prevalence of self-reported low back pain (LBP), and neck and/or shoulder pain (NSP) among secondary school teachers; and to evaluate the association of LBP and NSP with psychological distress and work-related psychosocial factors.

    METHODS: This was a cross-sectional study conducted among teachers in the state of Penang, Malaysia. The participants were recruited via a two stage sampling method. Information on demographic, psychological distress, work-related psychosocial factors, and musculoskeletal pain (LBP and NSP) in the past 12 months was collected using a self-administered questionnaire. Poisson regression was used to estimate the prevalence ratio (PR) for the associations between psychological distress and work-related psychosocial factors with LBP and NSP.

    RESULTS: The prevalence of self-reported LBP and NSP among 1482 teachers in the past 12 months was 48.0% (95% Confidence Interval (CI) 45.2%, 50.9%) and 60.1% (95% CI 57.4%, 62.9%) respectively. From the multivariate analysis, self-reported LBP was associated with teachers who reported severe to extremely severe depression (PR: 1.71, 95% CI 1.25, 2.32), severe to extremely severe anxiety (1.46, 95% CI 1.22, 1.75), high psychological job demand (1.29, 95% CI 1.06, 1.57), low skill discretion (1.28, 95% CI 1.13, 1.47) and poorer mental health (0.98, 95% CI 0.97, 0.99). Self-reported NSP was associated with mild to moderate anxiety (1.18, 95% CI 1.06, 1.33), severe to extremely severe anxiety (1.25, 95% CI 1.09, 1.43), low supervisory support (1.13, 95% CI 1.03, 1.25) and poorer mental health (0.98, 95% CI 0.97, 0.99).

    CONCLUSIONS: Self-reported LBP and NSP were common among secondary school teachers. Interventions targeting psychological distress and work-related psychosocial characteristics may reduce musculoskeletal pain among school teachers.
