- GCMAS - A comparison of normal kinematics for Vicon Clinical Manager and Plug in Gait Vicon Clinical Manager (VCM) is a commercial gait analysis software package whose underlying model is based on those devised by Kadaba, et al., (1990) and Davis, et al., (1991). VCM calculates lower extremity kinematics and kinetics. Recently, a model named Plug in Gait (PIG) was developed to emulate VCM with some slight differences in filtering. The purpose of this study is to determine whether there is a difference in kinematics when using VCM and PIG.
- GCMAS - Assessment of the Kinematic Variability between Twelve Shriners Motion Analysis Laboratories Over the past several years, the Shriners Hospitals for Children have developed recommendations for standards for clinical examination, kinematic assessment and EMG technique. The goal of this project was to evaluate the change in between site variability following implementation of a standardized training program.

- ISB - Clinical usefulness of four functional knee axis algorithms Four functional algorithms have been proposed to resolve the challenge of identifying the true flexion/extension (F/E) axis of the knee during gait. The functional axis algorithms of Woltring , Halvorsen et al. , Schwartz and Rozumalski  and Baker et al.  were selected for comparison.
- ISB - Influence of thigh marker cluster design The purpose of this study was to evaluate various thigh marker cluster configurations with a view to optimising the estimation of hip axial rotation.

- GCMAS - Dynamic knee axis alignment By providing clinicians with an objective comparison of different functional axis algorithms and by illustrating the constraints associated with each, practitioners will be able to make informed decisions about which method to employ and when it is appropriate to use them. Ultimately, these decisions may lead to improved treatment planning and better evaluation of treatment outcomes.

- Gait classification – A step in the wrong direction This study investigates whether naturally occurring categories of gait pattern exist for children with hemiplegic cerebral palsy (CP) using multi-dimensional scaling. There is no evidence of such categories. Given this a factor analysis is used to determine factors accounting for the variability between individual gait patterns.

- 2st Joint ESMAC-GCMAS Meeting (JEGM) Effects of Aquatic Therapy in Ankylosing Spondylitis: A Case Study
Soft tissue artefacts and anatomical landmarks mislocation represent the main sources of errors in movement analysis. The localization of anatomical landmarks for calibration purpose results critical because of the interposition of soft tissues and because the anatomical entities to be identified are small areas rather than geometrical points. Ultrasound imaging can be integrated with a conventional stereophotogrammetric system, in order to obtain the 3D image of relevant bony prominence and then the identification of anatomical landmarks. Purpose of the present work was to develop a calibration procedure which overcomes the main limitations in terms of time consumption, accuracy and easiness of use of the previously proposed procedures.
