Pengaruh Senam Ergonomi Dalam Mencegah Musculoskeletal Disorders (MSDS) pada Ibu Rumah Tangga RT 11 Kelurahan Bagan Pete

Safety at home is an important aspect that needs to be considered to protect yourself and your family. Although often considered less risky than formal workplaces, homes also have potential hazards that can threaten safety and health. Around 1.71 billion people worldwide experience musculoskeletal disorders (MSDs). One of the non-pharmacological treatments that can be applied for MSDs is ergonomic exercise. However, the low understanding and awareness of housewives about ergonomic hazards due to daily activities is a problem. Many mothers carry out housework without adequate knowledge of ergonomic principles, thus increasing the risk of MSDs. Therefore, it is important to increase public awareness of the benefits of ergonomic exercises, which can help maintain health and minimize the risk of musculoskeletal disorders during activities at home. This study aims to analyze the effect of ergonomic exercises in preventing musculoskeletal disorders (MSDs) in housewives in RT 11 Bagan Pete Village. Results showed an increase in knowledge of ergonomic work hazards, with a probability value of p < 0.001, which indicates significance below 0.05. The mean pre-test score of participants was 10.13 (SD 5.476), while the mean post-test score increased to 18 (SD 1.259). In addition, the change in musculoskeletal complaints after stretching was also significant, with a p-value of 0.002. This shows that stretching has a positive impact in reducing musculoskeletal complaints among housewives. In conclusion, the ergonomic exercise service program not only increases knowledge and skills regarding good posture, but also provides more energy and reduces muscle pain. This activity succeeded in raising awareness of the importance of ergonomics in daily activities, which is expected to reduce the risk of injury due to household chores.

Gym-Related Injuries and its Prevention and Treatment Strategies

In contemporary society, health and fitness have received more and more attention and become an important venue for the public to pursue physical health and good posture. However, in the actual fitness exercise, because most exercisers lack the correct cognition of their own athletic ability, physical condition and movement norms, in the daily exercise process, there will often be unpredictable sports injuries. At the same time, the lack of professional knowledge in the self-treatment of injury leads to the aggravation of injury, which has a negative impact on all aspects of daily life such as my study and work. However, current research on fitness related sports injuries is relatively limited. Through the analysis of the characteristics of sports injuries, understanding the causes of sports injuries in current fitness exercises can provide an important reference basis for how to correctly deal with and prevent common sports injuries, and then improve the fitness consciousness of our people at the social level, and help the construction of a well-off society in an all-round way.

Walking as a Modality for Enhancing Physical Fitness: A Review

Walking plays a key role in maintaining overall physical fitness which is essential for good health. Physical fitness consists of two main aspects health-related and skill-related components. It is commonly measured by assessing cardiovascular endurance muscle strength muscle endurance flexibility and body composition. This review conducted a comprehensive literature search using reputable publications such as Elsevier, PubMed, PubMed Central, and other relevant sources. The search focused on peer-reviewed studies that examine the effects of walking on physical fitness. Many studies highlight walking as a simple and accessible form of exercise that offers significant benefits such as improved cardiovascular endurance muscle strength and flexibility. It is recommended to engage in at least 150 minutes of walking each week for optimal benefits. To maximize walking's impact on fitness it is crucial to maintain good posture and proper breathing techniques. In addition to physical benefits walking also promotes mental and social well-being. It is a versatile activity suitable for all ages including adolescents, adults, children, seniors, and individuals with specific health conditions or diseases. By understanding the connection between walking and fitness people can incorporate it into their daily routines to enhance overall health. Future research could focus on specific fitness aspects related to walking to develop personalized guidelines for different populations.

Ergonomics in Facial Plastic and Reconstructive Surgery: A Clinical Evaluation.

Surgeons experience a risk for physical strain and injury secondary to physical demands in the workplace. To minimize injury and maximize career longevity, physicians should be aware of ergonomics pitfalls and postural correction methods. This study investigates ergonomic trends in Facial Plastic and Reconstructive Surgery (FPRS) clinic by quantifying surgeons' and trainees' cervicothoracic spine posture. Participants completed a 22-item questionnaire to evaluate current ergonomic practices. A lightweight device was calibrated and attached to the mid-scapular region of participants, providing real-time posture feedback. The percentage of time in upright posture was recorded during clinical and operative workdays. Upright posture was defined as neutral spine positioning with acceptable mild to moderate deviations. Two FPRS attending surgeons, 1 FPRS fellow, and 11 otolaryngology residents participated over 12 months. Discomfort was most commonly reported in the neck, shoulders, and upper back during clinic. Symptoms were self-treated by changing body position, wearing specialized footwear, adjusting height of the chair or examination table, or ignoring discomfort. Eighty-two percent were unaware of ergonomic guidelines or appropriate considerations. Time spent in upright posture was significantly higher in clinic (84.9%) than in the OR (53.5%) (p < 0.001). Upright posture declined after reaching 6 work hours (p = 0.029); no such patterns were observed in the OR (p = 0.946). Although time spent in upright posture was objectively poorer in the OR, these data suggest ergonomics are an important consideration in the outpatient setting, with surgeons experiencing discomfort during and after clinic. Further investigation is warranted to identify actionable changes and promote healthy ergonomics. N/A Laryngoscope, 2024.

Real-Time Forward Head Posture Detection and Correction System Utilizing an Inertial Measurement Unit Sensor

Forward head posture (FHP) has become a prevailing health issue in modern society as people spend more time on computers and smartphones. FHP is a posture where the head is forward and the anterior and posterior curvatures of the lower cervical and upper thoracic spines are both, respectively, exaggerated. FHP is often associated with neck pain, bad static balance, and hunched shoulders or back. To prevent this, consciously maintaining good posture is important. Therefore, in this study, we propose a system that gives users real-time, accurate information about their neck posture, and it also encourages them to maintain a good posture. This inexpensive system utilizes a single inertial measurement unit sensor and a Raspberry Pi system to detect the changes in state that can progress to an FHP. It retrieves data from the sensor attached to the user’s cervical spine to indicate their real-time posture. In a real-world office environment experiment with ten male participants, the system accurately detected the transition to the FHP state for more than 10 s, with a delay of less than 0.5 s, and it also provided personalized feedback to encourage them to maintain good posture. All ten participants recognized that their average craniovertebral angle had to be increased after receiving visual alerts regarding their poor postures in real time. The results indicate that the system has potential for widespread applications.

A period of backwards walking affects the craniovertebral angle, proprioception, balance, and foot pressure on forward head posture of female students

PurposeThe presence of spinal arches is crucial for maintaining good body posture, reducing pressure on joints, and preventing deformities caused by misalignment. Engaging in exercises that focus on correcting body alignment, such as walking backward, can enhance posture and various related factors. MethodA group of 46 female students suffering from forward head posture was selected (age: 22.89 ± 2.31 years, height: 1.63 ± 0.05 m, weight: 60.01 ± 5.41 kg, body mass index: 22.38 ± 1.28 kg/m2) and randomly divided into two groups. The intervention group participated in three exercise sessions per week for four weeks, while the control group did not receive any intervention during the study. Changes in the craniovertebral angle, proprioception, resistance, and foot pressure were measured using photogrammetry, head-neck angle examination with a laser pointer, a balance measuring device, and a foot scanner. FindingsThe results of this study showed that the training program had a significant effect on the craniovertebral angle (P = 0.001), neck proprioception (P = 0.001), balance (P = 0.001), and sole pressure (P = 0.001). Likewise, the results of the group comparison revealed significant differences in various variables, such as the craniovertebral angle (P = 0.001), neck proprioception (P = 0.001), balance (P = 0.001), and plantar pressure (P ≥ 0.05). ConclusionThis study demonstrated that walking backward enhanced the craniovertebral angle, proprioception, balance, and alterations in the plantar center of pressure. Therefore, this exercise is recommended as a complementary therapeutic approach for individuals with forward head posture.

Intervertebral disc deformation in the lower lumbar spine during object lifting measured in vivo using indwelling bone pins

Object lifting is often categorized into squat and stoop techniques, with the former believed to protect the back by maintaining a neutral spine, and the latter considered harmful due to spinal flexion. Despite the widespread promotion of these beliefs, there is no evidence to support such dichotomy, as spinal flexion is not conclusively linked to low back pain. This study aimed to investigate intervertebral disc deformation in the lower lumbar spine during squat and stoop lifting using indwelling bone pins. Five healthy males underwent insertion of Kirschner wires into the L3, L4, and L5 spinous processes, followed by biomechanical data collection using magnetic and optical tracking systems during upright standing, isolated flexion/extension, and object lifting with both squat and stoop techniques. Except for one subject, stoop lifting resulted in up to 90 % greater disc wedging compared to squat lifting, with a significant difference at L4/L5 (p = 0.042). The anterior annulus fibrosus experienced 10 % to 40 % more compression during stoop lifting, but no significant differences were found in posterior annulus fibrosus expansion between techniques. Lever arms were about 35 % longer during stoop compared to squat lifting. These results indicate that even though stoop lifting generally led to greater disc deformation, significant deformation was also observed during squat lifting, challenging the notion of maintaining a neutral spine with this technique. Moreover, the considerable variability observed among participants raises concerns about the suitability of current one-size-fits-all lifting guidelines.

Child development is currently experiencing significant progress. However, children often experience posture problems such as scoliosis, lordosis, kyphosis, and shoulder asymmetry. If not treated immediately, this problem can continue into adulthood. To find out what is wrong with a child's posture, it is important to find it early. Posture correction is also important for children with posture problems. This counseling aims to teach how to diagnose scoliosis in oneself, prevent it in teenagers and increase awareness and knowledge about maintaining health and good body posture. Scoliosis education methods for children include health promotion, use of posters, pre-tests and post-tests, as well as education about scoliosis. This activity was attended by 27 participants aged 11 - 12 years at SDN Polowijen 1 Malang City. The consequences of this action show an increase in student information about scoliosis with a normal pre-test average of 62.8% to a post-test of 96.2%.

A LiDAR-Based Recommendation System to Improve Sitting Posture Respecting Privacy.

Poor posture is becoming more widespread due to the rising number of jobs that require workers to sit for extended hours. Maintaining proper leg positioning is essential for good overall posture and long-term health. However, current monitoring methods involve multiple sensors and cameras, leading to discomfort and privacy concerns. This paper presents a privacy-preserving recommendation system using Light Detection and Ranging (LiDAR) to monitor leg positions. The system captures the horizontal leg outline at knee height and extracts domain-specific features, while a stacked autoencoder reproduces the latent representation of the leg outline. The system comprises three modules, including one-class and multi-class support vector machines, to identify 15 leg positions and reject unrecognized ones. Data from 30 healthy volunteers during work activities trained the system. When tested on new participants, the system achieved an accuracy of over 98%. In addition to monitoring leg positions while respecting privacy and ergonomics, our system alerts workers about poor leg positions and generates intuitive dashboards with posture statistics that help safety engineers identify at-risk workers and body parts. This offers a promising solution for improving desk workers' posture and reducing long-term health issues, respecting privacy.

The results of the research before being given the pregnancy exercise intervention were 28 people (54.9%) experiencing moderate back pain and 23 people (45.1%) experiencing severe back pain. After being given the pregnancy exercise intervention, 31 people (60.8%) experienced mild back pain and 20 people (39.2%) experienced moderate back pain. The results of statistical tests using the Wilcoxon test obtained a ρ-value of 0.000 so it can be concluded that there is an influence of pregnancy exercise in overcoming back pain in pregnant women. The advice given by this research is to implement a structured and regularly scheduled pregnancy exercise program. This can help reduce back pain and improve the well-being of pregnant women.

Conceptual Framework of Upper Cross Syndrome: A Delphi Study.

Upper cross syndrome (UCS) is one of the most common postural dysfunctions due to prolonged flexed attitude. Good posture plays an important role in maintaining musculoskeletal balance and protecting it from further injury. Conducting research on the conceptual framework will help clinicians to identify and plan treatment strategies for the correction of this syndrome and prevent secondary complications. Thus, the aim of this study was to develop a conceptual framework for UCS. The Delphi method was used to conduct the study and develop a conceptual framework. A total of 30 multidisciplinary experts participated in the study, and a list of 41 items was finalized after an extensive literature review. A cover letter along with all the items was mailed to the experts to obtain their input. Three rounds of Delphi were conducted until a consensus was reached. The following parameters were used to determine consensus: moderate Kendall's coefficient of concordance (Kendall's W), agreement greater than 51.0%, interquartile range (IQR) below 1.5, and standard deviation (SD) below 1. By the end of the third round, 37 items were finalized. The conceptual framework consisted of four items in postural alignment, eight items in muscular imbalance, 20 items in functional limitation, and five items in the psychosocial domain. We successfully developed a conceptual framework for UCS. Four domains, including postural alignment, muscular imbalance, functional limitation, and psychosocial, were identified. This will lead to a deeper comprehension of UCS, which will facilitate its early detection and treatment. The multidimensional approach of the study will provide a better scope for the clinicians to educate the patient about good posture, which not only will impact physical performance but also improve quality of life. The development of this framework will help to prevent, monitor the progress, and correct UCS.

A Randomized Controlled Trial of Active Stretching of the Hamstrings and Core Control for Low Back Pain and Musculoskeletal Discomfort during Prolonged Sitting among Young People.

Introduction: Stretching exercises are important in both the prevention and treatment of nonspecific low back pain (NLBP). The aim of this trial was to determine whether an 8-week active hamstring stretching protocol combined with core stabilization and education regarding the maintenance of a neutral lumbar spine during activities could reduce NLBP and low back discomfort during prolonged sitting among young people. Methods: Participants (52 students aged 18-25) were randomly assigned to one of two groups: the Experimental group (the hamstring stretching group) and the Control group (only education). The intervention was conducted for 8 weeks. The primary outcome measures were pain intensity (VAS), low back discomfort (LBD), and functional disability (ODI). The secondary outcome measures were satisfaction with the intervention (GPE) and flexibility of the hamstring (SLR). Results: After the 8-week intervention in the E-group, results of VAS, ODI, and LBD were significantly lower comparing to baseline. In the C-group, no significant differences were observed. After the exercises program, there were differences between the E-group and C-group in VAS, LBD, GPE, and SLR tests (p < 0.05, p < 0.05, p < 0.05, and p < 0.0001, respectively). Conclusions: In conclusion, our study provides compelling evidence that an eight-week program of active hamstring stretching and core stabilization exercises can significantly reduce NLBP and musculoskeletal discomfort during prolonged sitting in young adults. These findings highlight the importance of targeted exercise interventions in managing and preventing NLBP, particularly among sedentary populations. Further research is warranted to confirm these findings and explore their applicability to broader populations and over extended periods.

Relationship between Learning Environment Design and Musculoskeletal Disorders in Learners

Introduction: Students spend most of their day at school sitting in their classroom furniture which is not quite the right size for students. This can be uncomfortable and even lead to back pain, leg cramps, and other problems. Method: Students’ body size for good posture while sitting, include popliteal to floor height, elbow to seat height, thigh thickness, sitting height, buttock to popliteal length, buttock to knee length, elbow to elbow breadth, the width of bitrochanter, subscapular height, and sitting shoulder height, and one standing is stature. Similarly, dimensions of chair-with-table, like seat height, the upper edge of the backrest, seat width, seat depth, table length, table width, table height, backrest height, and footrest currently used in the classroom were taken. The study compared students' anthropometry data with the furniture dimension data to obtain a match or mismatch between them with the help of standard mismatch equations. Results: The study reported that the mean body measurements of males are larger than females except for the width of bitrochanter. Seat width, seat depth, backrest height, and the upper edge of the backrest showed high mismatch percentages in students when patronising chairs. Table length reported high mismatch percentages among students. Conclusion: Using the users’ body sizes for furniture design will reduce musculoskeletal disorders and improve users’ sitting position. The recommended dimensions in furniture design will ergonomically fit students’ anthropometric measurements.

Advancing Virtual Interviews: AI-Driven Facial Emotion Recognition for Better Recruitment

Behavior analysis involves the detailed process of identifying, modeling, and comprehending the various nuances and patterns of emotional expressions exhibited by individuals. It poses a significant challenge to accurately detect and predict facial emotions, especially in contexts like remote interviews, which have become increasingly prevalent. Notably, many participants struggle to convey their thoughts to interviewers with a happy expression and good posture, which may unfairly diminish their chances of employment, despite their qualifications. To address this challenge, artificial intelligence techniques such as image classification offer promising solutions. By leveraging AI models, behavior analysis can be applied to perceive and interpret facial reactions, thereby paving the way to anticipate future behaviors based on learned patterns to the participants. Despite existing works on facial emotion recognition (FER) using image classification, there is limited research focused on platforms like remote interviews and online courses. In this paper, our primary focus lies on emotions such as happiness, sadness, anger, surprise, eye contact, neutrality, smile, confusion, and stooped posture. We have curated our dataset, comprising a diverse range of sample interviews captured through participants' video recordings and other images documenting facial expressions and speech during interviews. Additionally, we have integrated existing datasets such as FER 2013 and the Celebrity Emotions dataset. Through our investigation, we explore a variety of AI and deep learning methodologies, including VGG19, ResNet50V2, ResNet152V2, Inception-ResNetV2, Xception, EfficientNet B0, and YOLO V8 to analyze facial patterns and predict emotions. Our results demonstrate an accuracy of 73% using the YOLO v8 model. However, we discovered that the categories of happy and smile, as well as surprised and confused, are not disjoint, leading to potential inaccuracies in classification. Furthermore, we considered stooped posture as a non-essential class since the interviews are conducted via webcam, which does not allow for the observation of posture. By removing these overlapping categories, we achieved a remarkable accuracy increase to around 76.88% using the YOLO v8 model.

Design of Table and Chairs for Packaging Tempe Chips Work Station for Reducing the Risk of Occupational Diseases in Putra Tunggal Home Industry Wonosobo

Home Industry Putra Tunggal Wonosobo is a tempeh chip industry whose production process is manual, so it can have a negative impact on worker ergonomics. Preliminary research was conducted by interviewing pain complaints and assessing work posture using the OWAS method. The tempeh chips packaging workstation was the workstation that had the most pain complaints at 67.86% (19 of 28 body parts) and the highest OWAS score at 4, so this was at high risk of experiencing musculoskeletal disorders. The next study used the NBM questionnaire to analyze the level of pain due to work and RULA for work posture. CATIA software was used to design tables and chairs, as well as assess the posture of the design results using the RULA method. Worker performance will be compared before and after using tables and chairs based on the level of body pain due to work (NBM) and work posture (RULA). The research results showed a decrease in the risk of work-related diseases by 80 and 78 to 40 and 44 (from high to low-risk levels) as well as a decrease in the RULA score from 7 (dangerous posture) to 2 (good posture).

Prevalence of Neck Pain in Physiotherapist

Background: Neck pain is one of the most common musculoskeletal disorders among health professionals, including physiotherapists, who are often involved in activities that include holding a posture for a longer duration and performance of repetitive movements. The increased usage of smartphones and laptops enhances bad postures, particularly bending of the neck in flexion, adding to the problems related to neck pain. Objective: The present study has been taken up to assess the prevalence of neck pain among physiotherapists and their relation with gender and age. Methods: This was a cross-sectional study conducted on 100 physiotherapists, of which 63 were females and 37 were males. Neck pain prevalence was assessed with the Neck Disability Index questionnaire. Data collection was done in person from November 2023 to February 2024. Results were statistically analyzed, with descriptive statistics shown in tabulations, graphs, and figures. Results: The overall prevalence of neck pain among the participants was 64%. In accordance with the NDI scale, the physiotherapists self-reported 39% to have mild disability; 23%, moderate disability; only 2% were severely disabled and none with complete disability. On a gender basis, females revealed a slightly higher prevalence of neck pain, 25%, compared to their male counterparts, 24%. Conclusion: In this study, a high prevalence of neck pain was found among physiotherapists, with a slightly increased occurrence in females. These findings bring out the importance of increasing awareness toward ergonomic practices and health regarding posture to decrease neck pain in physiotherapists. The modifiable risk factors identified will have an emphasis on the promotion of good postures with lifestyle modifications to aid in the prevention of neck pain in physiotherapists. Making these changes and taking up appropriate treatments form an important aspect of the management of work-related musculoskeletal disorders.

Yak meat content in feed and its impact on the growth of rats.

To evaluate the effects of varying proportions of yak meat in feed on the growth of rats and provide a theoretical basis for selecting the optimal feed proportion suitable for rats. This study was designed as a one-variable experiment. Fifty male rats were divided into five groups. The ratios of yak meat to basal feed of rats in four dietary treatment groups were 2:8, 4:6, 6:4, and 8:2, respectively, while those in the control group were only provided a basal diet. In the feeding experiment, the body weights of the rats were recorded on Day 0 and subsequently in the first, second, third, and fourth weeks, along with quantities of feed intake. The body and tail lengths, as well as the waist circumference of the rats, were measured, and blood samples were collected in the fourth week for routine blood and biochemistry investigations. The rats in the 4:6 feed group had the best body condition. They had normal body and tail lengths, smaller waist circumferences, good posture, and were in better overall health than rats in the other groups. The results indicate that the 4:6 diet was optimal for enhancing rats' growth performance compared to the other diets.

Bilateral congenital muscular torticollis in infants, report of two cases

Background Congenital muscular torticollis (CMT) is a well-known diagnosis among physiotherapists specializing in pediatric care, especially when working with infants. However, knowledge of bilateral torticollis is limited. The purpose of this article was to describe how bilateral torticollis may present itself clinically. Case One infant with CMT with sternocleidomastoid tumor (SMT) on the right side, and some limitation in rotation towards the right side and in lateral flexion towards the left side, i.e, the muscle on the right side was shortened. While sitting with support, he tilted the head to the left and was stronger in the lateral flexors on the left side which fit well with a postural left-sided torticollis (PT). The other infant had bilateral muscular torticollis (MT), the sternocleidomastoid muscle thickened bilaterally, and both active and passive rotations were affected. The head was held in flexion, and active rotation was severely limited to both sides. For both cases the therapeutic interventions were to gain a normal range of motion (ROM) and a good posture of the head. Conclusions CMT can appear in different ways and may be bilateral. Both infants gained good ROM and better head position, however case I still needs some training. To gain more knowledge about bilateral CMT, we should follow these cases over a longer period of time. It is important to communicate and discuss our experiences with each other to understand rare cases of CMT.

Current Issues Related to Anthropometry in Engineering

Anthropos and Metrikos both mean "human" in Greek, which is where the term anthropometry comes from. Anthropometry is employed in a variety of fields, including apparel and textile design. For anthropometric evaluations, a current, thorough, and community-specific anthropometric normative-reference standard is necessary. In health care, ergonomic design is utilised to reduce pain and illness. Misalignments between humans and machines result in pain, accidents, biomechanical stress, tiredness, and musculoskeletal injuries. Designing for the anthropometrics of end users improves long-term viability. The human body comes in a wide range of sizes and shapes. Manual measurement and 3D scanning procedures, on the other hand, are inefficient and expensive, making precise body measurements difficult. This is especially true for head-worn medical devices. Manual measurement and 3D scanning are inefficient and expensive, making precise body measurements difficult. Grip strength and force were determined using hand measurements. Anthropometric parameter estimate is more precise when a 3D model is used to boost pinnae features. While numerous anatomical features have been gathered to aid in the ergonomic design of wearable devices, there is still a lot more work to be done. In three dimensions, the segment masses and torso Centre of Mass (COM) may be calculated. Researchers tracking mobility would benefit greatly from the ability to locate the body COM using a weighted sum of segment masses. Design features such as comfort and usefulness are crucial. Ergonomic characteristics like taller seats with front slopes and saddle chairs encourage good posture, movement, and alternation. In the creation of wearable technologies, using outdated anthropometric reference standards may be insufficient. This review discuses common issues related to anthropometry in engineering which includes the human body, anthropometric parameters, anthropometric measurements, the force plate method, ergonomic design, and body dimension. The goal is to give a broad overview of the subject.

REAL-TIME MOTION IMAGE POSE DECOMPOSITION, CLASSIFICATION AND ANALYSIS

Exercise can boost metabolism and make the body healthier. It also increases metabolic rate, helping to consume more calories and burn fat. Regular exercise can stimulate the brain to secrete endorphins, making people feel relaxed and happy, and improves self-confidence, and has been shown to reduce symptoms in people with depression and anxiety. However, incorrect exercise posture may cause harm to the body, such as torn ligaments or muscle strains, so good exercise posture is needed to improve sports performance. This article proposes to use artificial intelligence image analysis method to decompose fitness exercise posture images and establish exercise posture cycle samples to assist in completing fitness exercises.
