      abstract = {While alterations in spinal kinematics have been  frequently reported in patients with chronic low back pain  (CLBP), a better characterization of the kinematics during  functional activities is needed to improve our  understanding and therapeutic solutions for this condition.  Recent studies on healthy subjects showed the value of  analyzing the spine during sit-to-stand transition (STST)  using multi-segment models, suggesting that additional  knowledge could be gained by conducting similar assessments  in CLBP patients. The objectives of this study were to  characterize three dimensional kinematics at the lower  lumbar (LLS), upper lumbar (ULS), lower thoracic (LTS) and  upper thoracic (UTS) joints during STST, and to test the  hypothesis that CLBP patients perform this movement with  smaller angle and angular velocity compared to asymptomatic  controls. Ten CLBP patients (with minimal to moderate  disability) and 11 asymptomatic controls with comparable  demographics (52% male, 37.4±5.6 years old, 22.5±2.8 kg/m2)  were tested using a three-dimensional camera-based system  following previously proposed protocols. Characteristic  patterns of movement were identified at the LLS, ULS and  UTS joints in the sagittal plane only. Significant  differences in the form of smaller sagittal-plane angle and  smaller angular velocity in the patient group compared to  the control group were observed at these three joints. This  indicated a more rigid spine in the patient group and  suggested that CLBP rehabilitation could potentially be  enhanced by targeting movement deficits in functional  activities. The results further recommended the analysis of  STST kinematics using a pelvis-lumbar-thoracic model  including lower and upper lumbar and thoracic segments.},
