A review of research on techniques for lifting low-lying objects: 2. Evidence for a correct technique

Teaching 'correct' lifting technique is common, with squat lifting generally recommended. However the available evidence is less clear about which technique should be favoured. The purpose of this paper was to present an accessible synthesis of the evidence to assist professionals in their decision about whether to teach a specific technique for lifting objects lying on or near the ground. Squat, stoop and semi-squat techniques are described and the psychophysical, physiological, biomechanical, psychological, performance and clinical evidence for each technique summarised. Evidence for other lifting guidelines is also presented. It is concluded that no one technique has clear evidence and that a work design approach should be the prime focus of intervention. Recommendations for correct lifting technique guidelines are given for where technique training must be provided.
