While numerous efforts have attempted to provide quantitative guidelines for the prevention of initial low back disorders during material handling tasks, none have appeared in the literature that address the issue of recurrent low back disorders due to materials handling when returning to the workplace. A study comparing the spine loads of low back pain patients and asymptomatic controls was conducted. Subjects lifted weights varying from 4.5-11.4 kg at four vertical heights, two horizontal distances and five task asymmetries collectively representing common industrial lifting situations. Spine loading was calculated using a validated EMG-assisted biomechanical model. Spine loads observed during lifting tasks were compared to spine tolerance values believed to initiate low back injuries. In addition, the percentage of patients successfully performing the lift was noted and used as an indication of the willingness of the subject to perform the task. These evaluations are summarized in a series of three lifting guidelines indicating safe, medium risk and high risk lifting tasks for low back patients as well as asymptomatic workers. It is believed that adherence to these guidelines can minimize the risk of recurrent low back disorders due to occupational lifting.
Recent discussions over the plight of a woman who had spent a year sleeping in her wheelchair because the local NHS trust refused to allow her to be lifted into bed highlight the dilemma facing nurses when they are required to manually handle patients (Andrews and Robinson 2003). Nurses are acutely aware that the manual handling of patients can result in back injury (McGuire and Dewar 1993). Yet they are also aware that they owe a duty to patients to provide nursing care to meet their needs and that might only be achieved through manual handling. There is evidence that hospitals in particular have still not met the requirements of the Manual Handling Operations Regulations (Trevelyan 2000). The hazards of working in the community environment have generally been better addressed as part of the assessment for and delivery of individual care packages. This article considers the law's approach to balancing the opposing needs of nurses' and patients' health needs.
