• Description:
  Work musculoskeletal disorders (WMSDs) remain among the most prevalent occupational pathologies in industrialized countries, and existing evidence indicates that repetitive motions are an important risk factor. "Internal variation" offers a potential method for reducing or preventing WMSDs and which can be achieved by focusing on motor variability (MV). MV refers to variations in kinetic or kinematic aspects of a movement pattern and muscle activity, and suitable levels may help to reduce the risk and/or symptoms of WMSDs. Our long-term goal is to use MV as a means to develop useful tools for providing occupational guidelines, and ultimately to help decrease injury risks. Previous work indicates that experienced workers use more stable motor control strategies compared with novices. However, little evidence exists that has formally characterized MV differences associated with experience. Understanding variations in the movement of experienced workers may be one useful approach toward the noted guidelines. Thus, the goal of this research was to quantify how MV differs between experienced workers and novices. [Description provided by NIOSH]
