Worldwide children’s walking disabilities that are caused mainly by cerebral palsy display multiple conditions of both permanent and non-developing motor dysfunction that in turn upsets posture, mobility, or muscle tone in general. In order to estimate the influence of instrumented gait analysis on the walking ability in cerebral palsied children the Dynaport Minimod, based on a triaxial accelerometer was employed. A Dynaport Minimod was used for collecting the spatial and temporal gait data. An evaluation of the gait data carried out via online services application for 80 children with cerebral palsies from April 1 st , 2018 to October 30 th , 2019. The Dynaport Minimod is capable of capturing most of the spatiotemporal gait parameters which indicate that this technique is quite cooperative and objective in the detection of gait changes and the evaluation of consequences, respectively. The most useful practice for the managing of children with cerebral palsy is a gait analysis system in which its clinical utilization is considered to be a developing technology especially in providing guidance to service planning centres and hospitals.

Three-dimensional (3-D) kinematic analyses are used widely in both sport and clinical examinations. However, this procedure depends on reliable palpation of anatomical landmarks and mal-positioning of markers between sessions may result in improperly defined segment co-ordinate system axes which will produce in-consistent joint rotations. This had led some to question the efficacy of this technique. The aim of the current investigation was to assess the reliability of the anatomical frame definition when quantifying 3-D kinematics of the lower extremities during running. Ten participants completed five successful running trials at 4.0 m·s-1 ± 5%. 3-D angular joint kinematics parameters from the hip, knee and ankle were collected using an eight camera motion analysis system. Two static calibration trials were captured. The first (test) was conducted prior to the running trials following which anatomical landmarks were removed. The second was obtained following completion of the running trials where anatomical landmarks were re-positioned (retest). Paired samples t-tests were used to compare 3-D kinematic parameters quantified using the two static trials, and intraclass correlations were employed to examine the similarities between the sagittal, coronal and transverse plane waveforms. The results indicate that no significant (p>0.05) differences were found between test and retest 3-D kinematic parameters and strong (R2≥0.87) correlations were observed between test and retest waveforms. Based on the results obtained from this investigation, it appears that the anatomical co-ordinate axes of the lower extremities can be defined reliably thus confirming the efficacy of studies using this technique.

The aim of the research was to evaluate the results of NDT-Bobath method in gait re-education of adult patients after ischemic stroke using normalized parameters of gait. The investigation group consisted of 60 patients, all sufferers of an ischemic stroke, and participated in a rehabilitation program: 10 sessions of NDT-Bobath therapy through 2 weeks (ten days of the therapy). Normalized parameters of gait were calculated based on anthropometric measures of patients and their gait parameters (gait velocity, cadence and stride length) measured in every patient on admission (before the therapy) and after the last session of the therapy to assess rehabilitation effects. Results among patients involved in the research were as follows: in normalized gait velocity: recovery in 42 cases (70 %), relapse in 10 cases (16,67 %), no measurable changes in 8 cases (13.33 %)in normalized cadence: recovery in 39 cases (65 %), relapse in 16 cases (26.67 %), no measurable changes in 5 cases (8.33 %)in normalized stride length: recovery in 50 cases (83.33 %), relapse in 4 cases (6.67 %), no measurable changes in 6 cases (10 %). Observed statistically significant and favourable changes in health status of patients, described by normalized gait parameters, confirm effectiveness of the NDT-Bobath method.
