Edinburgh Visual Gait Scale (EVGS)
The EVGS was developed specifically for children with Cerebral Palsy and has stronger psychometric properties to enhance reliability. [7] The assessment is carried out in both the sagittal and coronal planes and evaluates the lower limb joint angles in both the stance and swing phases of gait. By incorporating the sagittal and coronal planes it allows for inferences to be made about the transverse plane and provides a more comprehensive representation of the child’s gait pattern than gait classification systems based solely on sagittal plane data. Similar to the other observational gait analysis scales, the EVGS has good intra-observer reliability, but poor inter-observer reliability. [5] [7] The EVGS has also shown good sensitivity to change in children with Cerebral Palsy following orthopaedic surgery and therapeutic interventions. [8] To ensure consistently good levels of reliability and sensitivity are achieved, the assessor must be well trained and experienced in the evaluation and application of the EVGS. [9] [10] It may be possible to use the EVGS to evaluate orthotic intervention, however further work is required to evaluate the sensitivity of the EVGS to gait changes following orthotic intervention.
