Criticality Analysis of Diabetic Gait Within a Primary Care Pediatric Clinic for Obese Children (PAIDOS)

This feasibility study aims to the do the following: 1. To evaluate the use of Criticality Analysis of Gait as means of Diabetes assessment. 2. To design and set up a clinical feasibility study in a hospital (Hospital Infantil de Mexico) with adolescent patients on different clinical stages of type 2 Diabetes mellitus (DM). 3. To analyse the collected data and validate Gait data analysis as mechanism for identifying and monitoring pre-diabetic teenagers. 4. To use the feasibility study conducted in Mexico to develop a robust method using Gait analysis for diabetes prevention and management. Participants will be selected from the Primary Care Pediatric Clinic for Obese Children (PAIDOS) in the Hospital Infantil de México Federico Gómez, Mexico City, Mexico. Sixty participants will be selected and divided into three groups: 40 obese non-diabetic subjects, 10 with Type 2 Diabetes and 10 healthy subjects as controls. Obese participants within the Paidos clinic will undergo standard clinical care that includes dietary prescription of caloric intake according to height, 150 min weekly physical activity, group cognitive-behavioural intervention, 6 session of obesity awareness and educational program. Gait will be recorded in all groups using a sensor on the 4th vertebrae of the lumbar spine, once a week across 6 weeks during the routine PAIDOS clinic. Critical changes in walking control, stride frequency and length will be observed as individuals change speed; effectively stressing their mobility. The study will be repeated after 3-6 months as a follow up. Data analysis will be performed in a semi-blind manner in order to test the efficacy of the criticality analysis Rate control of Chaos (RCC) model. In order to provide an objective measure of analysis, the anonymised data will be presented to the nonlinear RCC models, where results can be extracted and compared afterwards to known states.
