Interest of video analysis for the lower back pain patient: a premilinary study

摘要

Exercise therapy programme is a multidisciplinary programme in which physical training is a main component (Poiraudeau et al. 2004). Since 1985, Van Wingerden et al. (2008) have shown, especially for erector spinae (ES) in chronic low back pain (LBP) patients, a loss of rachidian mobility and a muscular performance decrease. Trunk stiffness is one of the most evaluated parameters during the rehabilitation programme. However, these evaluations, based on the finger/floor distance (FFS), do not take individual's particularities into account and do not give any information about muscle activity, muscular imbalance and strategies used during the flexion movement. To our knowledge, only a few movement motion analyses take an interest in the chronic LBP patient. One previous study analysed the forward-bending movement (Remy-Neris et al. 2001) and another one considered both flexion and extension and trunk inclination after vertebra break (Stuelcken et al. 2010).The purpose of this preliminary study is to evaluate the kinematic of the back during trunk flexion/extension movement in LBP patient included in a rehabilitation programme and to compare these results with a control group (CG). This was done to objectively evaluate the trunk subject's mobility. Through EMG, muscular activity was also determined to analyse the possible readjustment during the rehabilitation programme.
