This invention is an article of clothing or clothing accessory for measuring body motion, posture, and/or configuration comprising sets of multiple flexible electromagnetic, light, and/or sound energy pathways, wherein each set longitudinally spans the same body joint in a selected configuration to increase measurement accuracy. Multiple flexible energy pathways longitudinally spanning the same body joint can transmit the same type or different types of energy (e.g. electromagnetic, light, or sound) and can transmit energy flows with the same flow parameters or different flow parameters.
