Lumbar Load

Caregivers experience low back pain because of patient handling such as supporting standing-up. The lumbar load of a caregiver depends on the required force for patient handling motions. If the relationship between the required force and the lumbar load is quantitatively clarified, it may be useful for preventing low back pain in caregivers. In this study, we investigated the quantitative relationships between the required force and lumbar loads such as vertebral stress and muscle activity in supporting standing-up by computational musculoskeletal simulation. First, a musculoskeletal model of a caregiver was prepared, and then the model performed simulated supporting standing-up motions. The vertical load used as the required force was placed on the upper limb of the model. The compressive/shear stress of the vertebral (L4–L5) and muscle activities of spinae erector muscle group were recorded as the lumbar load. The results showed that there are highly significant correlations between the required force (r > 0.9, p < 0.01). In addition, regression equations for predicting each lumbar load by the required force with highly determination coefficients (R2 > 0.9) were obtained from these relationships. Furthermore, we found that when the required force was more than 120 N, the compression stresses of the vertebral exceeded injury threshold (3400 N) by the regression equation. These regression equations contribute to quantitatively consider lumbar loads of caregiver during patient handling based on injury thresholds and the required force.

Most caregivers have low back pain which results from frequent care activities such as assistance motion that supports transfer and standing-up. Various parameters are associated with the caregiver’s lumbar load. In this study, we focus on the foot position of the caregiver as one of the subjective adjustable parameters. This study aimed to analyze the relationship between foot position and stresses of the L4–L5 joint as lumbar load during supporting standing-up via musculoskeletal simulation. The musculoskeletal model was tasked with simulating supported standing-up motions based on a specific pelvic position and angular variation of each joint. The anterior foot (left foot) was fixed, and the posterior foot (right foot) was moved to three backward positions and three rightward positions, thus obtaining nine posterior foot positions. Compressive, anteroposterior shear, and lateral shear stresses of the L4–L5 joint were compared for nine foot positions. The results showed that as the anteroposterior distance and lateral widths between both feet increased, the average value of compressive/shear stress of the L4–L5 joint during motions decreased. From our findings, we hypothesized that the foot position may reduce the lumbar load and prevent low back pain.

Abstract Background Low back pain is a common public health problem throughout the world with the global prevalence from 28–86%. Nurses working in intensive care units are handling people who are critically ill and helpless, which requires more assistance for transferring and handling activities. This possesses a risk for low back pain but little is known about it in Ethiopia. The aim of this study was to assess the magnitude of low back pain and associated factors among nurses who work at an intensive care units in Amhara region public hospitals, North Ethiopia. Methods A multi-centered institution-based cross-sectional study was conducted at Amhara region public hospitals from March 1–30/2020. Simple random sampling technique after proportional allocation was used to select the study participants. Data were collected using a standard modified Nordic musculoskeletal assessment tool. After data were checked for completeness and consistency, it was entered into Epidata version 3.1 and exported to Statistical Package for Social Science software version 26 for analysis. Descriptive statistics were computed. A binary logistic regression model was used to identify factors associated with low back pain. Finally, those variables with a p-value of < 0.05 in multivariable analysis were considered statistically significant. Result -The study was conducted among 412 intensive care unit nurses giving a response rate of 97.6%. The magnitude of low back pain was 313 (76 %) [95% CI: (71.6%-79.9%)]. Being female [AOR = 2.674 (1.404, 5.076)], unavailability of assistive device for patient handling [AOR = 2.139 (1.035, 4.410)], lack of training on intensive care [AOR = 2.017 (1.092 ,3.943)], lack of regular exercise [AOR = 2.164 (1.164 ,4.108)] and job stress [AOR = 3.66 (1.955, 6.498)] were factors significantly associated with low back pain. Conclusions In this study the magnitude of low back pain was high. Being female, unavailability of assistive device for patient handling, lack of training on intensive care, lack of regular exercise and job stress were factors associated with low back pain. Policy makers and concerned bodies should give emphasis on accessability of assistive devices for patient care, provision of training on intensive care and adaptive working environment for intensive care unit nurses.

This study describes the effect of Active Corset on the lumbar spine. Active Corset is assist tools used to prevent low back pain. It tightens the waist optimally according to the lumbar load during work. This study aimed to clarify the mechanical effect of tightening of the pelvis on lumbar joints and determine the mechanism leading to reduction of the lumbar load. Moreover, this study examined the phenomena commonly occurring among the subjects with reduced lumbar load by tightening of the pelvis. First, we will present some examples of currently used assist tools and demine the utility of the Active Corset among the various tools used. Next, the mechanism of the Active Corset will be described. Further, we will present a hypothesis about reducing the lumbar load by tightening the pelvis. After describing the change in the joint bending angle on tightening, we will describe reduction of burden from the antigravity torque around the lumbar joint. Finally, we will compare active tightening using Active Corset with tightening using a constant force and describe the advantage of active tightening.
