Exercise therapy (ET) is currently an important component in the treatment of NSCLBP. Previous studies analysed the effects of various modes of exercise therapy, such as motor control therapy, core stability training and aerobic conditioning training. However, therapy outcomes can be low, and guidelines in favour of using a specific program are contradictory. It thus still remains unclear which therapy modality is best suited. Furthermore, no recommendations are available about optimal training intensities during rehabilitation of persons with NSCLBP.
