Brief Summary
Gait disturbances can be observed in all age groups, and may be due to different conditions, such as advanced age, stroke, head trauma, spinal cord injury, cerebral palsy, myelomeningocele, among others. The aforementioned gait disorders are associated with an increased risk of falls (which can cause major fractures or head trauma), decreased mobility, loss of independence, cardiovascular pathology, and decreased quality of life. In order to improve a given abnormal gait pattern, an objective assessment of gait is necessary. There are several methods to carry out gait evaluations, like Instrumented Gait Analysis (High cost, time-consuming, qualified professionals needed) and the ones based on observation (limited reliability and validity). An alternative, is the use of video-based systems. SILEMA (Computer System for Gait Study Laboratories in Argentina) is a video-based low-cost gait analysis system that measures temporo-spatial (speed, step length, cadence, stance and swing times) and joint kinematic (Hip, Knee, Ankle) parameters. Its reliability has not been reported yet; thus the primary aim of this study is to determine both the "intra-evaluator" (same evaluator, different sessions) and "inter-evaluator" (same session, different evaluators) reliability.

Interventions
SILEMA consists of a webcam connected to a laptop, a LED reflector, and a software. To carry out gait analysis with SILEMA, an Evaluator must place six yellow auto-adhesive markers over certain anatomical landmarks in the lower limbs, namely, greater trochanter, external femoral condyle, head of the fibula, lateral malleolus and base and head of the fifth metatarsal. The patient is asked to walk barefoot through an eight meter walkway at a self-selected speed, while a webcam connected to a laptop records a video. Then, an Operator, making use of the software, processes the video, obtaining spatio-temporal and joint kinematic parameters.
