Abstract
Three methods of measuring ranges of motion (ROMs) in persons wearing protective clothing were evaluated. The study group consisted of ten healthy male volunteers, 19 to 31 years old. ROMs of motion for elbow flexion, shoulder flexion, shoulder extension and abduction, hip flexion and abduction, and knee flexion were measured by goniometers, electrogoniometers, and Flexometers with the subjects wearing nine types of protective clothing. The clothing types consisted of undersized, appropriately sized, and oversized light weight, medium weight, and heavy weight coveralls made of 4.25 ounce/square yard (oz/yd2) 65:35 polyester/cotton and 7.25 and 10.0oz/yd2 50:50 polyester/cotton cloth. ROMs for each body movement were also measured with the subjects wearing only athletic shorts, briefs, socks, and shoes (control condition). The electrogoniometer sensors were placed on the right elbow, hip, and knee joint and the shoulder. For all clothing types, the goniometer data were positively correlated with the Flexometer data, although measurements obtained with the goniometer were consistently larger than those obtained with the Flexometer. Correlations between the electrogoniometer and the Flexometer and goniometer were poor. For each instrument type, the ROMs tended to be smallest for the undersized clothing and largest for the oversized clothing. The authors conclude that goniometers probably represent the best choice for measuring ROMs of persons wearing protective clothing.
