TL;DR: Evidence is provided that clinically acceptable errors are possible in gait analysis, andVariability between studies, however, suggests that they are not always achieved.

TL;DR: The study concludes that GDI and GPS are alternative and closely related measures that have prior art and are particularly useful in applications arising out of feature analysis such as cluster analysis or subject matching.

TL;DR: It is concluded that the NFOG-Q is a reliable tool to detect and evaluate the impact and severity of FOG, and adding a video does not add to the sensitivity and specificity of Fogs detection but influences the estimation of Fog severity.

TL;DR: Specific and accurate assessment of gait can be a useful tool to monitor MS evolution and can be used to advise target-oriented rehabilitative management of MS patients.

TL;DR: The 6DOF set showed comparable performance to the conventional set and overcomes a number of theoretical limitations, however further development is needed prior to clinical implementation.

TL;DR: Distortion of the earth magnetic field is depending on construction materials used in the building, and should be taken into account for calibration, alignment to a reference system, and further measurements, and "mapping" of the laboratory is essential to obtain valid data.

TL;DR: Results of this study suggest that between-leg differences in swing and pre-swing time variability, increased step length and stride time variability and decreased width variability are quantifiable markers of impaired walking performance poststroke.

TL;DR: There is a need for further research of more rigorous methodological quality, including greater consensus regarding standards for reporting of electromyographic parameters, to evaluate the literature pertaining to the effect of foot posture, foot orthoses and footwear on lower limb muscle activity during walking and running.

TL;DR: In this study, one subject was evaluated by 24 examiners at 12 motion analysis laboratories and the observed variability of nine kinematic parameters are reported.

TL;DR: The results indicate that shoes with elevated heels or soft soles impair walking stability in older people, especially on wet floors, and that high-collar shoes of medium sole hardness provide optimal stability on level dry, irregular and wet floors.

TL;DR: It is concluded that there is an interaction between age and gait velocity in the amplitude and timing of antagonist muscle coactivation.

TL;DR: Attenuated hip abduction, frontal ROM and sagittal ROM during gait in FAI individuals may be caused by soft tissue restriction, and decreased frontal pelvic ROM could result from limited mobility at the sacro-lumbar joint.

TL;DR: Mean total velocity and phase plane portrait parameters are suggested as good candidates to use for quantification and assessment of balance performance and identifying those with MSDs.

TL;DR: Results support Kramer et al.'s proposal that VP training improves both single-task automatization and the development of task-coordination skills, as well as improving both balance and cognitive performance under dual-task conditions.

TL;DR: There is a clear need for prospective evaluation of kinematic gait characteristics in a PFPS population to distinguish between cause and effect, and future PFPS case-control studies should consider evaluating kinematics of the knee, hip and foot/ankle simultaneously with larger participant numbers.

TL;DR: It is hypothesized that failure to effectively recruit both hip flexor and ankle plantarflexor muscles of the paretic side limits the potential to increase walking speed in lower functioning hemiparetic subjects.

TL;DR: It is concluded that hamstring strains during sprinting most likely occur during terminal swing as a consequence of an eccentric contraction.

TL;DR: In this article, a tri-axial accelerometer, fixed to a belt at the level of the L3 spinous process, was used to measure trunk acceleration and the acceleration signal was sampled at the rate of 200 Hz.

TL;DR: The main finding was that the time-dependent structure of the COP trajectories of dancers exhibited less regularity than that of non-dancers, as evidenced by a higher sample entropy (decreased statistical regularity) and COP irregularity also increased during secondary task performance but decreased during standing with eyes closed.

TL;DR: The AMC is a valid method of measuring scapular movement during arm elevation that could be used in shoulder pathologies and should be carefully considered and elevation of the humerus should not exceed 100 degrees.

TL;DR: Findings demonstrate, for the first time, a direct relationship between fear of falling and the strategies used for human postural control.

TL;DR: The results of this study demonstrate that the DynaPort system, which allows measurements in real life conditions, is a highly valid tool for assessment of spatio-temporal gait parameters for averaged step data across a walkway length of approximately 20m in independent living elderly.

TL;DR: Gait is symmetrical in healthy children and young adults but may change with pathology, and may not be mature by age 13, while footwear significantly affected gait.

TL;DR: The findings suggest that the DGI, although susceptible to ceiling effects, appears to be an appropriate tool for assessing function in healthy older adults.

TL;DR: Results showed that the hardware platform and algorithms used can discriminate various types of falls from ADL with a sensitivity of 97.5% and a specificity of 100%.

TL;DR: Findings on spatiotemporal parameters indicate that a reduction in gait velocity and cadence and an increase in double support time for the 20% lower configuration could be a compensatory mechanism for children to minimize either the induced gait instability or mechanical strain on the musculoskeletal system.

TL;DR: It was concluded that the increased mechanical work for the step-to-step transition from prosthetic to intact limb contributes to the increased metabolic energy cost of amputee walking.

TL;DR: The effects of age and gender on gait parameters were found to be consistent with those reported in studies using other methodologies and support the application of AGA for routine clinical use and in daily life.

TL;DR: Whether body sway measured with a three-axial accelerometer at the trunk can differentiate between three healthy young populations that differ in athletic skill level is determined and quantifying the stochastic-dynamical structure of postural sway using ambulant accelerometry may provide a useful diagnostic tool is implied.

TL;DR: Young and older adults were shown to contact obstacles infrequently when adequate time was available to adapt foot placement in relation to the obstacle, but older adults contacted obstacles more often than younger people.
