OBJECTIVE: The aim of this study was to assess the effects of work improvement module using a Kiken Yochi participatory approach intervention in reducing MSS among male migrant pineapple farm plantation workers in Pontian, Johor.
METHODOLOGY: In this interventional study, a total of 68 male migrant workers from two plantation farms were invited to become a participant in this study. In total, 45 participants that consisted of 27 workers for the intervention group and 18 workers for the control group were recruited. The background of workers and MSS were assessed using questionnaires. Ergonomic and postural risks were evaluated and the work tasks with the highest risk were used as a basis for the development of the Kiken Yochi training module. MSS education and training intervention that provided information on proper lifting techniques and education on body mechanics and ergonomics to reduce MSS were implemented to both groups of workers. Kiken Yochi Training was given to the intervention group only. MSS were reassessed after 2 months of the follow-up period. Data was entered into statistical software and were analysed according to objectives.
RESULTS: In terms of the postural risk assessment, almost two-third of the participants (68.5%) had working postures categorized as high risk for MSS. Ergonomic risk assessment identified cultivation, manual weeding and harvesting of pineapples as the work tasks contributing the highest health risks to workers. The most commonly reported MSS between both groups of workers were at the knees, lower back and shoulder area. Upon completion of the delivery of intervention module to both groups of workers, the MSS prevalence reported (after 2 months) were significantly lower for the ankles and feet area within the intervention group.
CONCLUSION: This study suggested that development and implementation of programs using effective participatory approach training methods are able to prevent selected musculoskeletal problems for this occupation. To enhance the effects of such trainings, modifications of work tools in this occupation are desirable.
OBJECTIVE: This study aimed to examine the relationship between specific physical and psychosocial factors and/or ergonomic conditions on MSD symptoms among dentists in Malaysia.
METHODS: A group of 85 dentists was asked to complete a questionnaire to determine whether their complaints were related to physical and psychosocial factors and/or ergonomic conditions in their practices.
RESULTS: Among the nine reviewed body areas, the shoulders were most often affected by symptoms of MSDs (92.7%). Moreover, MSDs of the neck and upper back were most likely to prevent these practitioners from engaging in normal activities (32.9%). In general, no significant differences were found in the prevalence of MSD symptoms in relation to gender, age, body mass index, years in practice, number of patients, and frequency of breaks.
CONCLUSIONS: Our results were consistent with those reported in other studies that focused on MSD problems among dentists in other countries. To reduce the prevalence of MSDs, more attention should be paid to instituting ergonomically sensible approaches in the dental practice setting.
OBJECTIVE: To determine the prevalence of self-perceived emotional distress and its relation to work-related musculoskeletal disorders (WRMSDs) in nurses.
METHODS: A self-administered questionnaire survey was carried out on 660 female nurses working in public hospitals in the Klang Valley, Malaysia. The validated Malay version of the standardized Nordic musculoskeletal questionnaire (M-SNMQ) was used to identify the annual prevalence of WRMSDs; perceived emotional distress was assessed using the validated Malay short version, depression, anxiety, and stress (M-DASS) instrument. In addition, socio-demographic and occupational profiles of the participants were considered. Factors associated with WRMSDs were identified using logistic regression analysis.
RESULTS: A total of 376 nurses completed the survey (response rate 83.3%). 73.1% of the nursing staffs experienced WRMSDs in at least one anatomical site 12 months prior to the study. 75% of nurses expressed emotional distress. Of these, over half also reported anxiety and stress. Multiple logistic regression analysis showed that stress and anxiety significantly increased the risk of WRMSDs by approximately twofold.
CONCLUSION: There were significant associations between emotional distress and WRMSDs. Future longitudinal studies are therefore needed to investigate and identify the sources of emotional distress (non-occupational and occupational) to be used to establish preventive strategies to reduce the risk of WRMSDs.
OBJECTIVE: To review the prevalence of illness, stress, and corresponding risk factors among educators in Malaysia.
METHOD: Scopus, ProQuest, PubMed, ScienceDirect, CAB, and other computerized databases were searched according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to identify studies published between January 2013 and April 2019 on the prevalence and associated risk factors of illness and stress among educators (S1 Checklist). The keywords used included educator, teacher, lecturer, academic staff, teaching profession, university staff, academician, faculty, illness, injury, disease, pain, WMSD, dysphonia, hoarseness, stress, mental health, strain, health problem, disorder, and/or Malaysia. Selected studies were evaluated by quality assessment.
RESULTS: Twenty-two articles fulfilled the eligibility criteria. The prevalence of illness and stress was determined for low back pain (33.3-72.9%); upper back pain (33.33-56.4%); neck/shoulder pain (40.4-80.1%); upper arm discomfort (91.3%); forearm pain (89.6%); wrist pain (16.7-93.2%); hip pain (13.2-40.9%); thigh discomfort (91.8%); lower leg discomfort (90.5%); knee pain (23.7-88.0%); ankle/feet pain (19.3-87.7%); elbow pain (3.5-13.0%); voice disorder (10.4-13.0%) and stress (5.5-25.9%). Sex, education level, teaching experience, quality of life, anxiety, depression, coping styles, and others were reported as associated risk factors across the studies.
CONCLUSIONS: There appears to be a cause for concern regarding musculoskeletal disorders, voice disorder, and stress reported among educators in Malaysia. While most risk factors matched those reported in studies elsewhere, others such as school characteristics (school level, government or private school, and location [rural/urban]) have not been investigated.
METHODS: A cohort of 611 male Malaysian Army recruits were recruited and followed up at 3 and 6 months. Pain catastrophising, MSD, sociodemographic and work factors were measured using a self-administered questionnaire, and MSI incidence was retrieved from the medical records. Multivariable fixed effects regression was used to model the cumulative incidence of MSD and MSI.
RESULTS: Approximately 12% of the recruits were diagnosed with incident MSI and 80% reported incident MSD. Higher pain catastrophising at baseline was associated with higher 6 month MSD risk (adjusted OR (aOR) 1.6 per 1 SD increase of Pain Catastrophising Scale (PCS) scores; 95% CI 1.2 to 2.0), and longitudinally associated with MSD incidence (aOR 1.2, 95% CI 1.1 to 1.4). Pain catastrophising was not associated with MSI incidence (aOR 1.0, 95% CI 0.8 to 1.3). The association between pain catastrophising and self-reported MSD was stronger among recruits with self-reported past injury (p for interaction <0.001).
CONCLUSIONS: Pain catastrophising was able to predict symptomatic MSD, and not physician-diagnosed MSI, and these findings are directly related to individual health beliefs. Pain catastrophising has a greater influence on how military recruits perceived their musculoskeletal conditions during training, and efforts to reduce pain catastrophising may be beneficial.
Results: The findings showed piano players have a higher NDI, lower CVA, and RSP when compared with the non-piano players at a statistically significant level of p-value <0.05.
Objective: Playing-related musculoskeletal disorders (PRMSD) are a common problem for the pianist. The poor upper body ergonomics influences the natural positioning of the neck and shoulders, which involves forward head posture (FHP) and rounded shoulder posture (RSP). This misaligned position could produce a sensation of pain over the upper body, which affects the piano player and computer users with similar ergonomic posture. Recently, photogrammetry methods are commonly applied in a clinical setting to assess posture. The goal of this research is to compare the upper body playing-related muscu-loskeletal disorders between the piano and the non-piano players by applying photogrammetry.
Materials and Methods: This causal-comparative study includes 70 participants with 35 piano and 35 non-piano players. The participant's FHP was assessed using a digitized photo to record the Craniovertebral angle (CVA) with the support of Kinovea software. Besides, digital Vernier Calliper used to assess the scapular index on the RSP and Neck disability indices (NDI) used to measure neck pain and functional disability of the participants.
