Biomechanical assessment of work tasks and musculature.

Normal healthy volunteers were used to document the combined use of two methods of functional assessment, involving two dimensional biomechanical evaluation of submaximal lifting technique and maximum isometric lumbar extension strength, to predict maximal lifting capacity. The maximum isometric lumbar extension strength of 15 men and 11 women aged 18 to 39 years were evaluated. The submaximal lifting mechanics were also documented while lifting a light load from the floor to the standing position five consecutive times. This multifaceted functional assessment protocol was able to accurately predict a subject's maximum lifting capacity to within 10% or 11 pounds. The protocol was found to be more accurate when assessing men's lifting capacity than when assessing women's. The authors conclude that this prediction method may be beneficial to the rehabilitation of those with low back pain or it may prevent injuries by assigning appropriate activities or tasks for an individual's strength capabilities and biomechanical techniques.
