The purpose of this MSE Capstone Project is to prevent further damage to the lower back by educating the user about everyday hazards. Thus improving that person's quality of life since occupational health and sports injuries have an expanding impact so a wiser or more informed community is needed. The process was to define the parameters of the intervertebral disc, run the analysis of the force, compare the results and then formulate the mathematical equation that represents the compressive force acted upon the L5/S1 disc. The activities tested were standing, sitting, lifting with and without twisting at various weights and heights. Since body weight is a factor, the BODY Mass Index (BMI) is calcualted and then its respective body strength is computed to determine the offset of the force from the object moved. This allows for a full range of forces evaluated for each unique person. These activities are further defined in the parameters table. It is assumed that the user is a healthy person that has correct posture and the load weight is uniform. This makes the spine and the ground perpendicular to each other. After checking the compressive forces calculated from the individual standing, sitting and lifting with and without twisting, the force formula was within two percent of the results from the proven lifting equations such as NIOSH and the Manual Lifting Task equations. The maximum force was evaluated by the upper limit of 45 degrees for twisting, 60 degrees for bending, 30 kilograms for the object's weight and a BMI of 35. The average height of Americans of 168 centimeters was collected via the census over a 40 year period.   Copy/Holding information Location Collection Call No. Status   Walter Schroeder Library Master's Theses AC805 .P755 2008 Available Add Copy to MyList Format: HTMLPlain textDelimited Subject:   Email to:
