Abstract
Introduction: Gait analysis is fundamental for assessing the functional capacity and motor skills of any individual, therefore a reliable and specific analysis method is required to study gait in different populations. However, the reference values of gait parameters currently used in Colombia used gait parameters come from studies conducted on population groups from other countries or regions. Objective: To identify the reference values of gait kinematic parameters in healthy Colombian young adults. Materials and methods: A quantitative, descriptive and cross-sectional study was conducted. The sample consisted of 155 Colombian young adults (aged 18 to 25). Temporal and spatial parameters and kinematics data of each participant were measured through 3D motion capture, which was performed using 8 infrared cameras (Bonita 10) and the VICON NEXUS 1.8.5. software. POLYGON 4.1. software was used for data analysis, and statistical analysis was performed using the STATA 12.1. software package. Results: Average age, height and BMI were 20.3 years, 1.66m and 21.91T kg/m2, respectively. 41.29% of participants were male. The average values obtained for the step rate, stride time, speed and initial swing temporal and spatial parameters were as follows: 103 steps/min, 1.16 seconds, 1.01 m/s, and 59.62% of the gait cycle (both sides), respectively. Conclusion: Normal gait kinematic and temporal and spatial parameters of a group of healthy Colombian young adults were obtained, which will allow establishing the characteristics of abnormal gait in this population, improving intervention strategies, and designing and implementing technical aids aimed at improving locomotion in Colombian individuals.

Normal gait kinematic and temporal-spatial parameters of a group of healthy Colombian young adults were obtained, which will allow establishing the characteristics of normal gait in this population, improving intervention strategies, and designing and implementing technical aids aimed at improving locomotion in Colombian individuals
The following temporal-spatial gait parameters were measured in all participants: cadence, stride period, opposite foot-off, step time, single support, double support, foot-off, stride length, step length, and walking speed
Summary
Gait analysis is fundamental for assessing the functional capacity and motor skills of any individual. Gait is a rhythmic and cyclical activity that engages the entire body, especially the lower limbs, to generate the characteristic bipedal locomotion of humans.[1] Exploring and analyzing gait in the context of the clinical and functional evaluation of human body locomotion constitutes a fundamental tool to uncover possibilities of movement, the capacity to fulfill different daily activities, and the level of social interaction of each individual.[1] For this reason, the aims of computerized gait analysis include establishing a differential diagnosis of related illnesses; assessing the severity, extension and nature of injuries; monitoring changes in the presence and absence of intervention or treatment; and predicting the outcomes of these interventions.[2] In this regard, there are observational methods[1] available in clinical practice that have been used in combination with quantitative parameters to achieve accurate gait analyses. All these aspects allow accurately interpreting the outcomes.[3,4,5]
