“…In fact, Evans [19] produced a lumbar spine fracture using cadavers with a 277 kg compression loading. The traditional recommendation of adopting a squat posture for lifting a load when it can be brought close to the body is based on a shorter moment arm of the body weight and the load actingiat the L ,IS1 disc.…”

“…In some works on allied structures postmortal changes are mentioned. Evans and Lissner (1959), in a study on biomechanics of the human lumbar spine and pelvis obtained at autopsy, noted that embalming tended to harden and stiffen the specimen and to increase the average maximum load.…”

“…However, both age and degeneration of the discs have been shown to reduce this value. In fact, one study by Evans (1959) produced a lumbar spine fracture with as low as 277 kg of compression loading. By testing maximum pull strengths, Troup (1968) estimated 527 kg as the average maximum compression force at the lumbosacral level for young, physically fit, male adults, assuming a 25 per cent abdominal pressure assistance.…”

Abstract-Gross body actions involved in heavy industry. e.g. lifting and carrying materials. are often the cause of injury to the musculoskeletal system. A computer model is developed which treats the human body as a series of seven links from which reactive forces and torques are computed at each articulation during various simulated materials handling tasks. In addition, an analysis of shearing and compressing forces at the lower lumbar spine is included. The assumptions of the present model are presented, along with a discussion of future models.IT HAS been reported by Troup (1965) that a relatively large portion of industrial injuries (as great as 12 per cent) are back disorders resulting from a lifting task. It is also evident from papers by Tichauer (1965), Raof et al. (1960) and Davis et al. (1965) that the estimation of stresses on various parts of the musculoskeletal system during lifting activities will require a complex methodology which takes account of such factors as (1) instantaneous positions of the extremities and trunk, (2) curvature changes in the spine, (3) strength variations within different muscle groups and people, and (4) abdominal pressure effects.
