   What problems did the researchers set out to study, and why?
 
Conflicting evidence exists on what strategy is most effective in preventing back injury during lifting. The researchers examined how low back loading is affected by lifting strategy and the size and height of the load being lifted. They hypothesized that placing one foot beside the load to be lifted while assuming a kneeling position with the contralateral limb would reduce spinal loading but would induce asymmetrical spinal loading when lifting wide loads.


   Who participated in the study?
 
Twelve male subjects with no history of low back pain (mean age of 26.1 years, SD = 26.1).


   What new information does this study offer?
 
Large extensor moments about the joints of the lumbar vertebral column are produced by the paravertebral musculature during lifting. These moments . . . [Full Text of this Article]


   How did the researchers go about the study?
 

   How might the results of this study apply to patients who are treated by physical therapists from this point forward?
 

   What are the limitations of the study, and what further research is needed?
