    An analysis of trunk kinematics and gait parameters in people with stroke
    (AOSIS, 2018) Titus, Adnil W.; Hillier, Susan; Louw, Quinette A.; Inglis-Jassiem, Gakeemah
    Background: Approximately two out of three people with stroke experience gait problems. Trunk movement control and symmetry is an important prerequisite for functional walking gait. Movement control, measured objectively as kinematics during walking gait, is rarely investigated. Objective: To describe the three-dimensional (3D) kinematics of the trunk during gait in people with stroke, including key spatiotemporal characteristics. Methodology: A total of 17 adults with stroke who met the inclusion criteria were selected to participate in this cross-sectional pilot study. An eight-camera T-10 Vicon system with Nexus 1.8 software (Vicon Motion System Limited, Oxford, UK) was used to analyse the 3D kinematics of the trunk during self-selected walking speed. Trunk kinematics throughout the gait cycle and spatiotemporal parameters were extracted using custom-built scripts in MATLAB used at the Stellenbosch University Movement Analysis Laboratory. Stata Version 12.1 software was used to assess differences in trunk kinematics between the affected and unaffected sides during gait using the Sign test (statistical significance level p < 0.05). Results: Participants achieved functional gait speeds although they presented with asymmetrical trunk kinematics. During the full gait cycle, there were statistically significant differences of trunk motion between the affected and unaffected sides in the coronal plane (p < 0.001). There were statistically significant differences in the trunk kinematics between the affected side and unaffected sides at initial contact (p < 0.001) and foot off (p < 0.049) in the coronal plane as well as at initial contact (p < 0.000) and foot off (p < 0.013) in the transverse plane. Conclusion: This pilot study found significant asymmetry in trunk motion between the affected and unaffected sides that varied across the gait cycle. This suggests the trunk may need to be targeted in clinical gait retraining post-stroke.

    ENGLISH ABSTRACT: Introduction The trunk plays an important role in the symmetry, balance and stability of the lower and upper body during gait. Approximately two out of three people with stroke experience gait restrictions. Objective To describe the three dimensional kinematics of the trunk during gait in people with stroke. Methods Seventeen subjects that met the following inclusion criteria: males and females 18 years and older; a single cardiovascular incident; ability to follow simple instructions and to walk 10 metres without assistive devices; were recruited by means of convenience sampling for this observational pilot study. The eight-camera T-10 Vicon system with Nexus 1.8 software and the Plug-in-Gait (PiG) model (Vicon Motion System Limited, Oxford, UK) were used to capture the participants during walking at a self-selected speed. Thorax kinematics and temperospatial parameters were analysed in MATLAB (The Mathworks, Natrick, MA) using custom built scripts. The differences between the two sides of the trunk (affected and less-affected) were calculated using the Sign test (statistical significance level p<0.05) (Stata software). Results During the full gait cycle there were statistically significant differences of thorax motion between the affected and the less-affected side in the coronal plane (p=0.049) and pelvic motion in the sagittal plane (p=0.049). At initial contact and foot off there were statistically significant differences of thorax motion between the affected and the less-affected side in all three planes, whereas the pelvic motion was only significantly different in the sagittal plane (p=0.000). In terms of temperospatial parameters, the participants showed symmetry in step/stride length and step/stride time. They managed functional gait speeds although they presented with asymmetrical thorax kinematics. Conclusion This pilot study found significant asymmetry in thorax motion between the affected and less-affected sides of people with stroke.
