“…However, this coordination is task‐dependent, as the arms can be uncoupled from the lower limbs for use in voluntary activities, such as carrying objects. Changing movement of the arms impacts locomotor coordination, with prevention of arm swing resulting in a switch from anti‐phase coordination between the pelvic and scapular girdles to an in‐phase pattern . Reduced arm swing is common in PD and correlates with rigidity and bradykinesia .…”

Successful locomotion depends on postural control to establish and maintain appropriate postural orientation of body segments relative to one another and to the environment, and to ensure dynamic stability of the moving body. This paper provides a framework for considering dynamic postural control, highlighting the importance of coordination, consistency, and challenges to postural control posed by various locomotor tasks such as turning and backward walking. The impacts of aging and various movement disorders on postural control are discussed broadly in an effort to provide a general overview of the field and recommendations for assessment of dynamic postural control across different populations in both clinical and research settings. Suggestions for future research on dynamic postural control during locomotion are also provided and include discussion of opportunities afforded by new and developing technologies, the need for long-term monitoring of locomotor performance in everyday activities, gaps in our knowledge of how targeted intervention approaches modify dynamic postural control, and the relative paucity of literature regarding dynamic postural control in movement disorder populations other than Parkinson disease.

“…As future work, it would be interesting to study the upper limbs and the trunk parameters (pelvic dissociation, deviation of the center of mass, etc.) in the assisted gait with a unilateral forearm crutch to analyze the symmetries regarding these parameters [ 35 ].…”

Influence of the load exerted over a forearm crutch in spatiotemporal step parameters during assisted gait: pilot study

BackgroundAssisted gait with forearm crutches is frequently performed during the recovery of musculoskeletal injuries of the lower limb. The amount of body weight applied to the crutch or crutches depends on the pathology and the treatment phase. The transition from assisted gait with two crutches to a single crutch is usually recommended when the subject is able to load the 50% of the body weight upon the affected member. An altered assisted gait will cause biomechanic alterations and, therefore, longer treatments and relapses. The aim of this study was to analyze the influence of 10, 25 and 50% of body weight applied to a forearm crutch during a unilateral assisted gait in the spatial and temporal step parameters to determine the load that produces alterations in gait biomechanics and the load that does not.MethodsEleven healthy subjects performed normal gait (NG) and assisted gait with a forearm crutch, in which the applied loads were: comfortable (C), 25 and 50% of their body weight. Vicon System was employed for gait recording. GCH System 2.0 and GCH Control Software 1.0 controlled the loads. The variables were: step length, step period, velocity, step width and step angle. Friedman test compared all the gait modalities: NG and the different loads. Wilcoxon signed-rank test analyzed ipsilateral and contralateral step parameters to the crutch globally and for each subject.ResultsFriedman test showed significant differences between NG, C, 25 and 50%, especially for step period and velocity. Wilcoxon test had significant differences only in 4 of the 20 general comparisons between ipsilateral and contralateral steps to the crutch. In the analysis by subjects, step length, step period and velocity showed 79/132, 110/132 and 58/66 significant differences, respectively.ConclusionsThe increase in the load exerted over a forearm crutch produced an increase in the step period, accompanied by a reduction of step length and gait velocity. Step width and step angle were not modified. The unloading of 25 and 50% of body weight on a single crutch is incorrect from the biomechanical point of view. Two crutches should be employed when the body weight to unload exceeds 10%.Electronic supplementary materialThe online version of this article (10.1186/s12938-018-0527-z) contains supplementary material, which is available to authorized users.

“…During lower speeds, the thorax and pelvis tend to rotate in the same direction, which means an in-phase pattern although a particular anti-phase coordination (moving in opposite directions) always appears during the movement (Dedieu & Zanone, 2012;Huang et al, 2010). The shift in pelvis-thorax coordination from in-phase to anti-phase with increasing velocity was found to depend on the pelvis beginning to move in-phase with the femur, while the thorax continued to counter rotate with respect to the femur (Bruijn, Meijer, Van Dieen, Kingma, & Larnoth, 2008;Huang et al, 2010;Lamoth, Beek, & Meijer, 2002).…”

Nordic Walking (NW) is an increasingly popular physical activity with beneficial health effects. Therefore, it is necessary to consider the effect of different factors that may influence its performance. The aim of this study was to compare the range of motion of the trunk and upper extremities during NW with conventional walking (W) at different walking speeds and ground slope. 16 healthy men participated in the survey (age 22.7±1.3 years, weight 75.5±5.3 kg, height 180±5.0 cm), who performed NW and W treadmill trials on inclines of 0% and 8%. The treadmill speed was self-selected for each subject at start for NW and then increased by 10 and 20%. VICON MX system was applied for 3D kinematic analysis. During NW, the range of motion of the pelvis in sagittal plane significantly increased compared to W (p = 0.002). During NW on flat ground at speed increased by 10 and 20% respectively, the range of motion at the shoulder joint in sagittal plane was considerably smaller (p = 0.010 and p = 0.035 resp.) than during W. The range of motion at the elbow joint was significantly higher during NW at self-selected speed and on 8% incline (p = 0.003) when compared to W. The same applies for speed increase by 10% (p = 0.011).
