A geometrical analysis tool for investigating muscle length change in cerebral palsy (CP) patients is presented. A subset of anatomically based geometries from the International Union of Physiological Sciences (IUPS) Physiome Project is used, which is derived from the visible human (VH) data set with muscle attachment information, and customised using volume-preserving free-form deformation (FFD), the 'host-mesh' technique. The model's intended use is to provide pre- and post-surgery assessment for muscle lengthening, a surgery performed to help slacken tight muscles and improve gait. The model is illustrated using healthy patient data from motion capture as a validation followed by three CP case studies to highlight its use. The methodology is presented in three stages, (1) a FFD of the complete lower limb, (2) a focused geometric study on the semimembranosus (SM) and gastrocnemius (GT) muscles, and (3) an improved hybrid mechanics-FFD approach as an improvement for future analysis, with differentiation between muscle and tendon lengthening, and contact detection between sliding muscles. Finally, the issues, limitations, in particular with the marker system, and model improvements are discussed.

“…Hip displacement is a further complication of cerebral palsy and is most prevalent in the group of children who do not walk (Hoffer 1986, Brunner et al 1997, Kuno et al 1998. Hip displacement is measured in the migration of the head of the femur away from the acetabulum and is divided into subluxation (typically >33% migration) and hip dislocation (typically >80% migration) (Scrutton et al 2001, Parrott et al 2002, Pountney et al 2002.…”

Children with severe types of cerebral palsy use adaptive seating systems to encourage function and assist in delaying the development of deformity. These systems are often assessed for and provided by occupational therapists. However, there has been no unifying policy or theoretical basis on which these systems are provided and research evidence is lacking, with studies tending to be small and non-controlled. The International Classification of Functioning, Disability and Health (World Health Organisation 2001a,b) aims to establish a common language for clinical practice as well as research, while bringing together the opposing social and medical models of health care delivery. This paper suggests that the ICF model is an ideal theoretical basis for adaptive seating system assessment and provision, given that these systems often conflict between the medical model of reducing or delaying impairment of body functions and structures and the social model of children and families accessing life and environmental situations through mobility and seating equipment. The paper considers all the domains of the ICF with regard to the current literature. It concludes that using the model in the context of providing adaptive seating gives occupational therapists both a powerful tool for communicating with children and families as well as managers and a basis for evaluating practice.

Video based human gait bilateral symmetry analysis and its validity for functional assessment after an orthopaedic surgery

A color marker based computer vision system was proposed to provide spatio-temporal and kinematic information of human gait. By detecting the markers from video sequences, this system provides quantitative gait pattern information for clinicians to evaluate the rehabilitation progress of the patients who had undertaken total knee replacement (TKR) and/or total hip replacement (THR) surgeries. The leg bilateral symmetry as an efficient feature for this evaluation purpose was proposed. To calculate this parameter, leg angle curve as a gait signature was introduced to describe the gait pattern. The symmetry is denoted by dynamic time warping (DTW) distance of this walking signature. Normal and abnormal gait can be distinguished based on the leg bilateral symmetry.
