TL;DR: It is concluded that arm swing should be seen as an integral part of human bipedal gait, arising mostly from passive movements, which are stabilized by active muscle control, which mostly originates from locomotor circuits in the central nervous system.

TL;DR: After careful consideration it was decided that the recommendations made in the previous Standardization proposal in 1983 regarding environmental conditions should be maintained.

TL;DR: The result indicated which features in inertial sensors' signals should be preferred for detecting precisely and accurately temporal events against a reference standard and the system is suitable for clinical evaluations and provides temporal analysis of gait beyond the common swing/stance decomposition, through a quantitative estimation of inner-stance phases such as foot-flat.

TL;DR: This study identified testing protocols that improve the reliability of measuring gait variability and recommends using a continuous walking protocol and to collect no fewer than 30 steps.

TL;DR: Higher muscle activity in the gastrocnemius was observed when running with a forefoot strike, which may imply a greater training load on the muscle and a tendency for injury.

TL;DR: Planus, rectus and cavus feet exhibited significantly different measures of foot structure and function, and gait pattern parameters were invariant across foot types.

TL;DR: Assessing the concurrent validity of kinematic data recorded using a marker-based 3D motion analysis (3DMA) system and a low-cost alternative, the Microsoft Kinect™ (Kinect), during a gait retraining session found this system could provide numerous advantages when compared to laboratory-based gait Retraining systems.

TL;DR: Compared with fixed speed treadmill walking, differences between SP feedback modes were predominantly found in the timescales of walking speed variability, while the gait pattern was similar between modes, suggesting that SP allows for more natural stride variability.

TL;DR: A method to measure stride-to-stride foot placement in unconstrained environments is developed, and whether it can accurately quantify gait parameters over long walking distances is tested.

TL;DR: Dual task activities adversely affect gait in cognitively impaired older people, and multiple fallers performed worse in each gait condition but the addition of a functional or cognitive secondary task provided no added benefit in discriminating fallers from non-fallers with cognitive impairment.

TL;DR: In subjects with four modules pre- and post-therapy, locomotor training resulted in improved timing of the ankle plantarflexor module and a more extended paretic leg angle that allowed the subjects to walk faster and with more symmetrical propulsion.

TL;DR: Nonlinear measures such as harmonic ratio (HR), index of harmonicity (IH), multiscale entropy (MSE) and recurrence quantification analysis (RQA) of trunk accelerations were calculated and found to be positively associated with fall history.

TL;DR: F was associated with reduced gait speed and stride length and increased double support phase and step width in normal and dual task conditions; these changes were most pronounced in those who restrict activities as a result of FOF.

TL;DR: SEMLS results in clinically and statistically significant improvements in gait and function, in children with BSCP, which were maintained at 5 years after surgery.

TL;DR: A systematic review of the literature shows that postural deficit may be dependent on experimental conditions in which patients with LBP have been assessed, and that between-group differences did not increase with increased complexity of sensory manipulations.

TL;DR: The results showed that a free-field vibrotactile NFT with Vertiguard(®)-RT device can improve balance in PD patients in everyday life conditions very effectively, which might led in turn to a reduction of falls.

TL;DR: This study shows that Variability, Phases and Tandem have the strongest association with age and are the earliest to demonstrate a poorer gait pattern with higher age.

TL;DR: The results from a standardized 10-meter walk test demonstrated that the IMU-based method has an excellent agreement with the clinically used stopwatch method, and the gait symmetry results were comparable with previous studies.

TL;DR: The potential of an ankle-foot exoskeleton with kinematic control that assists ankle extension during push-off is highlighted, because of the fast adaptation and the significant reductions in metabolic cost.

TL;DR: This is the first study to biomechanically compare these two treatments, and demonstrates that given the potential role of knee loading in osteoarthritis progression, that both treatments reduce this but lateral wedge insoles appear to have a greater effect.

TL;DR: The body of literature provides some evidence of a relationship between pes planus and increased lower limb motion during gait, however this was not conclusive due to heterogeneity between studies and small effect sizes.

TL;DR: The various uses of ultrasound to examine human muscle and tendon function are outlined, and some of the many technical issues associated with this method are described, including novel automated techniques that improve the efficiency of the analysis process.

TL;DR: IVGB training improves balance after 6 weeks of implementation, and the beneficial effects partially remain after training is complete, suggesting this training is superior to traditional physical therapy.

TL;DR: The results of this study indicate that the percentage of time of COP progression on the ICP, FFCP, FFP and FFPOP were approximately 7.0%, 4.8%, 48.8% and 39.4%, respectively, which can offer useful information for clinical rehabilitation in foot functional and structural evaluation.

TL;DR: It is concluded that the disproportionate recruitment of hip muscles with advanced age may have critical implications for maintaining independent mobility in old adults, particularly at steeper uphill grades.

TL;DR: The aforementioned surface effect, which occurs independently of the fatigue state, should be taken into account when interpreting the results of studies that use the treadmill in their experimental protocols, and when prescribing physical exercise on a treadmill.

TL;DR: Results suggest that the described methodology could provide a robust and accurate falls risk assessment and an alternative model using FTSS time alone resulted in significantly reduced classification performance.

TL;DR: Analysis of strategies for collision avoidance between two persons walking along crossing trajectories showed that collision avoidance is performed collaboratively and the crossing order impacts both the contribution and the strategies used: the participant giving way contributes more than the one passing first to avoid the collision.

TL;DR: Gait termination can detect both acute and lingering motor control strategy alterations following concussion, and altered propulsive and braking forces persisted despite all concussion participants achieving their baseline values on standard concussion clinical tests.

TL;DR: Spasticity parameters in both muscles were higher in children with CP than in TD children, showed moderate correlation with the MAS for both muscles and good correlation to the MTS for the MEH, and provides reliable and clinically relevant measures of spasticity.
