Indicators of the kinetics of locomotor stereotypes in healthy children in different speed ranges of movement

Purpose To determine the normative values of the kinetic parameters of gait in healthy children in different speed ranges of movement. Materials and methods Locomotor profile assessment by video gait analysis (CGA) was performed on an outpatient basis in 27 children (54 limbs), aged 10-13 years. The following variables were used and processed: peak negative hip, knee and ankle power (W/kg) (relaxation); peak positive power of the hip, knee and ankle (support push) joints (W/kg) (generation); the total positive and total negative power was calculated(for the hip, knee and ankle joints); total peak power; net peak power values and overall mechanical efficiency. Kinetics indicators were generalized according to the ranges of ranking of the absolute walking speed (km/h), taking into account the weight of patients. Quantitative characteristics are presented in the table as a median, percentile range of distribution of values (25÷75 %) and the number of observations (n) equal to the number of limbs. Results The normative kinetic parameters of gait are presented at a speed of movement in the range from 1.1 to 5.0 km/h in healthy children aged 10-13 years. A strong correlation was found between the values of the power of the reference shock during the formation of the reciprocal inhibition reflex of the shin sprain and the speed parameters of movement (r = -0.925, n = 142 and p function show_eabstract() { $('#eabstract1').hide(); $('#eabstract2').show(); $('#eabstract_expand').hide(); }
