Time based relations in gait analysis

Time based relations in gait analysis

Posted by Gonny Smit on Thu 05 Jul. 2012 - 5 minute read

In my last two blog posts, I wrote about static gait parameters. Specifically, what a single footprint can tell you and what kind of information you can get from the distance relationships between prints. Now it’s time to talk about all four paws, and the time based relationships between them. If you ask me, we’ve been saving the best blog post for last!

Temporal relations

Temporal relations are the parameters that have to do with time, such as timing and duration. This is where automation of gait research shows it true colors.

So why would you want to know about the timing of footfalls? Let’s say you have two rats that walk in exactly the same way, with the same distances between each paw print, and the same pattern of walking. But one gets to the other side faster. In theory, this is because one walks faster. In other words, while the distance between the successive placement of one paw remains the same, the time it took to move this foot, was less. The stride (stance plus swing phase of the foot) was faster, not longer. This might be caused by a shorter stance phase, a shorter swing phase, or both, depending on the disorder that underlies this symptom.

Before modern gait analysis systems were used, these temporal differences stayed obscured. Nowadays, systems like CatWalk XT can calculate over 30 different temporal gait parameters.

Temporal parameters in action

Let me give you some examples of these parameters in action:

Shorter stance

If your leg or foot hurts, you don’t want to put your weight on it. This is exactly what animal models of several disorders show. Animals are found to keep their affected paw on the ground for a shorter amount of time in studies on sciatic nerve injury [1,2,3,11], ischemic stroke [7], and arthritis [10]. Additionally, Hoffman et al. [8] saw this compensated in other paws, in study on arthritis.

When the stance duration decreases, the stand duration relative to the total stand and swing duration often also decreases, as Ferland et al. [5] show in their arthritis model. In a study of Encarnacion et al. [4] on ischemic stroke, all paws show shorter time on the ground, but a shorter duty cycle was only found in one paw.

Longer stance

Contrary, in spinal cord injury research [9] the hind paws stay longer in contact with the ground. This is compliant with the typical ‘dragging of the hind body’ seen in spinal cord injury models. This longer stance phase is also found in the Parkinson’s model used by Westin et al. [12].

Longer swing

In most instances, a shorter time on the ground is compensated by a longer air time of that paw, reflected in a longer swing duration. This is found in models of sciatic nerve injury [1,2,3,11] and arthritis [5]. Certain treatments are proved effective in studies on sciatic nerve injury [11] and spinal cord injury [6].

Decreased swing speed

In some instances, a decreased swing speed is measured, meaning that the longer air time does not result in a different stride length. Examples include models of sciatic nerve injury [1] and arthritis [5]. Galvan et al. [6] measured an increase in swing speed after the treatment of spinal cord injury models. In relation to the longer stance phase of their model, Westin et al. [12] also found a decreased swing speed.

catwalk phase dispersion

Inter-paw coordination

Inter-paw coordination is reflected in several parameters. For example, phase dispersions and couplings describe the relative placement of two paws, the “target” and the “anchor” paw, during one stride. Kloos et al. [9] found deficits that correlate with the amount of recovery in a spinal cord injury model, while Bozkurt et al. [1] found that this parameters was affected in pairs that included the affected paw, reflecting a delayed positioning of the delayed paw. This was also seen by Deumens et al. [3].
