Pressure Patterns S2 | Scoliosis
Assessment of the centre of pressure pattern and moments about S2 in scoliotic subjects during normal walking Authors: Nachiappan Chockalingam, Surendra Bandi, Aziz Rahmatalla, Peter H Dangerfield and El-Nasri Ahmed Background Research employing gait measurements indicate asymmetries in ground reaction forces and suggest relationships between these asymmetries, neurological dysfunction and spinal deformity. Although, studies have documented the use of centre of pressure (CoP) and net joint moments in gait assessment and have assessed centre of mass (CoM)-CoP distance relationships in clinical conditions, there is a paucity of information relating to the moments about CoM. It is commonly considered that CoM is situated around S2 vertebra in normal upright posture and hence this study uses S2 vertebral prominence as reference point relative to CoM. Purpose To assess and establish, the asymmetry in the CoP pattern and moments about S2 vertebral prominence during level walking and its re...
