Reaction time and strength in pregnant and nonpregnant employed women
1Texas Tech University, School of Nursing, Lubbock 79430.
The purpose of this study was to determine whether or not employed women, during pregnancy or the immediate postpartum period, differ from nonpregnant employed women in reaction time and upper extremity strength. Differences in reaction time, strength, and/or physical work capacity during pregnancy could have implications for maternal and fetal safety, and for job assignment, tool design, and work process design for expectant mothers. Balance is affected by changes in weight, body contour, and center of gravity shift (National Safety News 1979; 119:77-80). Awkwardness, fatigue, and tendency toward loss of balance could become critical, especially when rapid movement or reaction is required for safety or task performance.
