A systematic review made by the Norwegian University of Science and Technology, Karolinska Institue, Roessingh Research and Development, the University of Twente, the University of Southern Denmark and the Nordic Institute of Chiropractic and Clinical Biomechanics, has been published in the European Journal of Pain.
This review reveals that, although having an active lifestyle is usually recommended to reduce and prevent neck or low back pain (NLBP), it is not the amount of physical activity itself the key factor for improvement, since at least among blue-collar workers, physical activity may actually increase the risk. Thus, it is important to take into account the compositional nature of physical behaviour in NLBP patients, and the impact in other health factors.
