Abstract Though biomechanically determined guidelines exist for lifting, existing recommendations for pushing and pulling were developed using a psychophysical approach. The current study aimed to establish objective hand force limits based on the results of a biomechanical assessment of the forces on the lumbar spine during occupational pushing and pulling activities. Sixty-two subjects performed pushing and pulling tasks in a laboratory setting. An electromyography-assisted biomechanical…

Elbow-Height Handle and Staggered Stance Exhibited Greatest Force in Pushing and Pulling: A Study among Malaysian Adults

Introduction: Pushing and pulling activities are common in daily life and industrial workplaces. These activities are potentially contributing to muscle fatigue in the back and shoulder if not…

The Effects of Ramp Gradients and Pushing–Pulling Techniques on Lumbar Spinal Load in Healthy Workers

Effects of handle characteristics of manual hand tools on maximal torque exertions: a literature review

The study provides different points that can be applied to improve the design of hand tools with an emphasis on handle diameter, shape and material and highlights various methodological issues including interactions among variables affecting maximum torque strength, posture, torque exertion using one or two hands.

Extended compilation of autopsy-material measurements on lumbar ultimate compressive strength for deriving reference values in ergonomic work design: The Revised Dortmund Recommendations

This study continues previous collations, the latest is dated on 2001 including 25 usable out of 47 investigations totally and 66 newly discovered seemingly appropriate studies were collected via a systematic literature search, 11 of them were added for subsequent analysis.

Maximum strength levels for pulling and pushing handleless cartons in warehousing tasks

The results of this study indicated that the pushing strength for handleless cartons was almost twice the pulling strength for all exertion heights, and pulling strength can be maximised by wearing gloves to pull a 60-cm-wide carton.

Biomechanics Analysis of the Firefighters’ Thorax Movement on Personal Protective Equipment during Lifting Task Using Inertial Measurement Unit Motion Capture

The biomechanics analysis of thorax angle deviation and angular acceleration has shown that using FFs PPE significantly causes restricted movement and limited mobility for the FFs, and human factors such as age influences the angle deviation while wearing PPE and FFs’ BMI influences the angular acceleration without using PPE during the lifting activity.

Effects of tool grip span, workpiece orientation, moving direction, and working height on two-handed torque strength and subjective measures.

The findings can be used to develop guidelines and recommendations with regard to daily and occupational activities which require the use of both hands for force exertion with manual hand tools.

Low-Back Biomechanics and Static Stability During Isometric Pushing

Results suggest that cocontraction may be recruited to compensate for the fact that equilibrium mechanics provide little intrinsic trunk stiffness and stability during pushing exertions, and it is important to consider muscle cocontractions when evaluating the biomechanics of pushing exertion.

Wheelchair pushing and turning: lumbar spine and shoulder loads and recommended limits

It is concluded that manual wheelchair pushing and turning can pose biomechanical risk to the lumbar spine and shoulders and biomechanically determined wheelchair pushing thresholds are presented and are more protective than the closest psychophysically determined equivalents.

Association between spinal loads and the psychophysical determination of maximum acceptable force during pushing tasks

Pushing tasks have become common in manual materials handling (MMH) and these tasks impose different tissue loads compared to lifting tasks, which may be unrelated to risk of low back injury and psychophysics may be misinterpreting risk.

Pushing and pulling: personal mechanics influence spine loads

The more experienced firefighters produced less spinal compression and shearing forces when compared to the less experienced students under the same conditions, which indicated a more efficient technique.

Mechanical loading of the low back and shoulders during pushing and pulling activities

Initial and sustained exerted forces were not highly correlated with the mechanical load at the low back and shoulders within the studied range of the exerted forces.

Determinants and magnitudes of manual force strengths and joint moments during two-handed standing maximal horizontal pushing and pulling

This study focuses on the sensitivity of shoulder capacity to gender, handle height, exertion type (push or pull) and handle orientation for these tasks, providing guidance to aid design of pushing and pulling tasks in the context of shoulder physical capacity.

Trunk Muscle Use during Pulling Tasks: Effects of a Lifting Belt and Footing Conditions

The absence of a statistical interaction effect between the lifting belt and the footing condition (slipperiness) indicates that the belt did not alter the coactivation pattern and hence was not relied upon by the participants as a protective mechanism.

Force direction and physical load in dynamic pushing and pulling

It was found that across conditions the changes in force exertion were frequently reflected in changes in shoulder torque and low back torque although of a much smaller magnitude.
