New research on Non-motorized treadmills.

Facts:

•Non-motorised treadmill locomotion creates large reductions in tibial acceleration.
•Non-motorised treadmill locomotion increases lower limb muscular activation.
•Non-motorised treadmill locomotion decreases cycle time/increases step frequency.

Keep these things in mind when you are doing a treadmill gait analysis. We have discussed over and over again of the severe and misleading information gleaned from gait analysis, that it shows strategies around problems, often not the problem at hand. But, this is yet one more factor to keep in mind when you are doing such studies, that changing the surface and how and why any given work is being performed on a given surface/device, that the information can be tainted if you do not know exactly what you are dealing with.   

Few studies are perfect, look at all of the parameters they likely should, and understand the complexity of the model they examine in their entirety. None the less, there is information to glean from most studies that help to debate, refute or clarify working concepts presently proven or unproven. This study provides some conclusions as well, that should be take in, digested and then determined where, when and if appropriate for a client.

Gait changes on a treadmill

Something to ponder on those days when getting outside it just impossible because of weather.
Athletes might respond to fatigue differently when running on a treadmill compared with overground conditions, where pace is typically more variable.
“Before halfway, step length increased and cadence decreased, whereas during the latter stages, there were significant decreases in impulse and maximum force. Contact time decreased and flight time increased continually, but otherwise most gait variables did not change. The changes in contact and flight times suggested that athletes altered their gait so that more time was spent airborne to allow the treadmill to pass under them. In general, however, the runners maintained their techniques throughout the run. ”

Hi guys,

I’m hoping you can help.

I have a severely arthritic 2 MTPJ on my left foot.

It seems to trigger extreme hip flexor tightness which has twisted my whole body, right up to my neck and jaw.

I can’t seem to get any definitive answers as to how to turn off this protective hip flexor tightness. I’m concerned if it goes on much longer I’m going to develop bone spurs throughout my body. This would destroy my life.

Is there any surgery you recommend?

Or any type of Rocker soled shoe? I’ve tried MBT’s but I think the forefoot is stiff enough and my Hipflexor hasn’t calmed down properly.

Thank you so much if you decide to answer this

Richard

How does subtalar supination/pronation affect plane deviations farther up the chain, specifically at the pelvis? I was going over some notes and found something saying that increased pronation leads to increased frontal plane motion at the pelvis during gait, and increased sup leads to increased transverse plane motion. However, in this video I was watching, the clinician states that increased sup will lead to increased frontal plane motion. Is this not a contradiction? Can both be true? Thanks

Correction:
a. I was listening to pod 49, great job. I am sending a personal message to point out an error regarding body composition. Under water weighing is considered the 2 compartment “Gold Standard” however caliper testing is used more due to cost and ability to be used in the field. Loved the learning stuff I sent some stuff similar to what you were talking about to the school administration but it went no where.
Thanks guys, Mark

Blog reader:
Not very infrequently the foot tripod has been discussed. Especially the importance of the medial tripod (MT) has been of great benefit to me. Some kind of a peroneus paralysis was probably the cause of weak MT of the right foot. With a weak anterior muscle group or compartment. But what about the lateral tripod, ie the 5th distal end of the fifth metatarsal. Which muscles are most responsible for the foot stability here and what kind of exercises might be of therapeutic value? Thank you.

Dear Gait Guys,                                
I’ve had a problem for a while where my lower left leg whips across the midline of my body at the start of the swing phase. This happens immediately after my left foot leaves the ground and before my right foot makes contact. My left knee seems to be angled outward, and I think this is due to some sort of external rotation of the hip or femur during the the early part of my swing phase. I attached a picture to illustrate this problem in my gait. I recently came across a blog post you guys wrote (http://thegaitguys.tumblr.com/post/14262793786/gait-problem-the-solitary-externally-rotated) and under the possibilities as to why there isn’t enough internal rotation, the second option describes exactly what happens when I run. So my question is, what can be done to correct this improper gait pattern? Thank you very much for taking the time to read this.
Sincerely,
Matthew

1. from Eric on our FB page:

a. Had a 9yr old girl for a shoe fitting recently. She had a forefoot valgus, with a rearfoot that is neutral or slightly varus. Fairly high arch and rigid Midfoot for a child that age as well. usually a child’s foot is super flexible so this makes me wonder if it’s a compensation for a true FF varus. How do I tell if he has an anatomic FF valgus vs a compensated version?

b. I asked Blaise Dubois his opinion on Treadmill vs outdoor running and he mentioned that the literature indicates TM’s aren’t much different than outdoor. He cites (Wank 1998). To me, running feels completely different and I can’t run nearly as efficiently on a TM as outdoor. i know some people are the opposite, which i subscribe to specificity of training.

the question i have is what basis do you use for your opinion on different motor patterns? i agree with you, but the literature seems to disagree. this is a piece from cybex so of course it will be “pro-treadmill”, but they quote several studies that concur with Wank… http://media.cybexintl.com/cybexinstitute/research/Truth_on_Fit_Apr10.pdf

hope i’m not sending too many questions. i figure you can ignore them if you have too many from other listeners.

2. On the Hip Bio Pt 6 you mention ext rot leg to gain leg length.  This one has been racking my brain.  I could see how this could happen if the person supinates the foot at the same time, but is there some other external rotating mechanism occurring in the hip that would cause this lengthening?  Thanks,Ryan

Hi Gait Guys,

I am a chiropractor in South Africa, and find gait, biomechanics and running fascinating…I’m hoping to become a true gait geek one day.Reading your blog has taught me so much, you guys seem to look at gait from every angle and don’t take things at face value.

I would like to find out about your Shoe Fit Certification Program. Can people from outside the USA complete the course? Would I be able to take the exam online? and would it give me any creditation in South Africa

 Hope to hear from you soon.

 Regards, Claire

3. I have been watching your video’s on you tube.  I have a cavus foot in which I have had severe nerve pain, why is the high arch caused by nerve pain?

And would any of your exercises help with my nerve pain

Thanks,Wendy

4. Hi guys,
Found your youtube channel. Very interesting stuff. Have started reading up on the whole gait cycle. Its very interesting.
I have a quick question that I hope that you can help me with:
Are you aware of any correlation of hip impingement (cam/pincer) in terms of having an irregular gait cycle?
I am suffering from both CAM & PINCER impingement in my right hip. Had surgery in January, but they did not shave sufficiently off the bone, so going back to surgery soon.
I am therefore interested in seeing how surgery possible could help me with bettering my walk and strain on my lower back / leg / foot. And also in terms of looking into some theory on how to retrain myself in walking cycles.
The problem is, that this kind of rehab/research is not available here in Denmark. So would appreciate if you are aware of any research on the above, and would be able to point me in the direction of that.
Thank you – and keep those great videos coming. :-)
Best,
Terje (Denmark)

The Truth about treadmills. Our Triathlete magazine article finds its way to the TRi website.

Regarding our treadmill article in Triathlete magazine.
Most things in this world have a place, a function, an advantage and a disadvantage. It is the wise and informed that can extract what they need from a device to serve its purpose. Knives are useful but you can also cut yourself with them if you do not know what you are doing…..that doesnt mean you empty your knife drawer at the side of the road on garbage day !
