Does this guy have a short leg or what? How good are your eyes?

One again, we had the gait cam, investigating gait on the east coast. What do we see in this gent?

  • heel strike on out side of left foot with increased progression angle

he appears to be stabilizing the left side during stance phase. notice the upper torso shift to the left during left stance phase

  • abbreviated arm swing on right

note that ankle rocker is adequate on the left

  • body lean to right on right stance phase

gluteus medius weakness on right? short leg on right?

Good.

  • Did you also notice the loss of ankle rocker on the right, compared to the left? This results in less hip extension on that side as well.
  • He flexes his right thigh less than his right during pre swing and swing

external obliques should be firing to initiate hip flexion, perpetuated by the psoas, iliacus and rectus femoris. This does not appear to be happening.

All of this is great BUT nothing like being able to actually examine your patients is there? You can see how gait analysis can tell us many things, but they need to be confirmed by a physical exam.

Got Arm Swing?

We have written many times about arm swing. Click here for some of our posts here on Tumblr.

Here we are again at the beach. Look at the beautiful difference in arm swing from side to side in the guy carrying the bag. Makes you want to tell him to use a backpack, eh?

Never mind what it does to his gait

  • decreased arm swing on the carrying side
  • increased step length on the left side
  • increased thigh flexion of the left side
  • increased body lean and head tilt to right side (Take a look at this paper)

think about the increased metabolic cost. Think about what this  type of input (increased amplitude of movement unilaterally) is doing to your cortex!

keep your movements symmetrical, folks!

It’s that time of the year again….beach cam

 

With Dr Ivo’s yearly trip to the beach, we have some interesting footage. Today’s winner was this gentleman. We apologize for the shakiness of the camera, as he free handed it for this shot.

Note the following:

  • the lack of glute action and the  loss of ankle rocker; his hips NEVER extend past zero. In this case, if they did, he would probably fall forward., due to his abdominal weakness
  • To go along with this, we have some premature heel rise, to help him to move forward. As soon as his body mass passes over the foot, the heel comes up.

 

  • Note the forward posture of the head, to attempt to move his center of gravity forward

  • Note how his arm swing is only forward. Normally, we like to se the arms move posterior to the body

 

  • He does appear to use his abs to initiate flexion of the thigh. See how he picks up his leg and extends the knee suddenly? This is given away by the acceleration of the leg as he “kicks” it forward.

As you can see, no one is safe from the gait cam. We are everywhere and the army of gait geeks is growing.  Do yourself a favor. Train yourself and others to have ankle rocker, use their glutes to extend their thigh and initiate hip flexion with their abs, rather than the psoas and rectus femoris.
