Shoulder width stance (SWS) and bilateral feet side-by-side stance (FSS) configure the same dimension of BOS in AP aspect but the dimension of BOS in ML aspect is wider in SWS than in SFS.
When the foot placement changes from shoulder width stance (SWS), side-by-side stance (SSS), and nonaffected limb in the front stance (SFS) to affected limb in the front stance (AFS), the subjects tended to increase their postural sway after surgery and the progressive increment of CoPR.
Our results have highlighted the tendency of increased postural sway as the foot placement changes from bilateral feet shoulder width stance, bilateral feet side-by-side stance to tandem stance, as reported by previous studies investigating upright standing control features in stroke or normal subjects [ 17, 50].
The board should be long enough so that you can have a wide, shoulder-width stance while riding it.
He praised the car's proportions, width and stance.
The following data were calculated for each trial: stride length, step width, percentage stance time, and gait symmetry.
Pixel coordinates of the hindpaw position and frame numbers were converted into geometric and time variables, and the following spatiotemporal characteristics were calculated: stride length, step width, percentage stance time, and gait symmetry.
In brief, gait trials collected on naïve Lewis rats were used to predict the stride length, step width, percentage stance time, and the single-limb support phase for a weight- and velocity-matched Lewis rat.
To account for the effects of animal size and walking velocity, stride length, step width, percentage stance time, and the single-limb support phase were normalized to the predicted gait profile of weight- and velocity-matched naïve Lewis rats.
Stride length, step width, percentage stance time, and the single-limb support phase are known to be strongly correlated to an animal's walking velocity and weight, and failure to account for these sources of variation can reduce the sensitivity of subsequent statistical analyses [ 11].
With this prediction, velocity- and weight-independent residuals of stride length, step width, percentage stance time, and the single-limb support phase can be calculated by subtracting the predicted value for a weight- and velocity-matched Lewis rat from the measured value for a Lewis rat with MCLT sham or MCLT + MMT surgery.
