Background:In the past due to limitations in healthcare the aim for persons who had suffered a burn was survival. Now as medicine advances, with many options to improve recovery, the focus has moved from survival to maximising functional outcome for the person who experienced a burn. A common outcome of severe burnt individuals is the loss of joint range of movement due to contractures which affects their gait. Three-Dimensional Gait analysis (3DGA) is a useful tool used to investigate various gait abnormalities and has the potential to provide an in-depth understanding of burn’s gait patterns for intervention, planning and monitoring.
Methods:The current study will investigate the gait of 20 burns patients who have suffered from severe burns (>20% total skin surface) using 3DGA. Each burns patient will attend the Queensland Motion Analysis Centre where kinematic and kinetic data will be collected from a 10 camera Vicon MX motion analysis system and floor mounted AMTI force plates. The data collected will be compared to gender and age matched controls and analysed by a gait physiotherapist.
Discussion: It is anticipated that the burn’s population will display difference in gait kinematics and kinetics when compared to the control population specifically in the range of motion in joints which in-turn will affect the joint moments and power generation.
