Have misplaced Craig Payne's BootCamp notes.
The trials assessing frontal plane motion of the rearfoot with and without foot orthoses that Craig uses were they measured whilst subjects were shod or unshod?, thanks, mark

 

Re: frontal plane change rearfoot in orthoses shod/unshod

Craig, you there mate? or too busy worrying about how the AB's are going to go this weekend ......

 

Re: frontal plane change rearfoot in orthoses shod/unshod

I can't be on everyone's 'ignore list'. How about,

Is it possible to measure the frontal plane position of the rearfoot whilst the subject is wearing footwear?

 

Re: frontal plane change rearfoot in orthoses shod/unshod

Okay Mark, brilliant question, should get an award!
I would imagine not, therefore how can they, the authors, assume it would be the same?
Now for an equally brilliant reply (mr rothbart don't bother), mark

 

Re: frontal plane change rearfoot in orthoses shod/unshod

G'day Mark,

Felt guilty leaving you talking to yourself so a quick response from me. Can't recall the exact methodology of the studies you originally mention from Craigs bootcamp without reading them again I'm afraid. Obviously goes without saying that capturing kinematic data when wearing orthoses will have to be performed when shod though.

I suspect the point you are getting at is that looking at kinematics when shod may not be a fair representation? (i.e. how the shoe moves may not reflect how the foot is moving?) Previous research suggests you'd be right. Mounted external markers do appear to consistently over-estimate skeletal movement. See attached light reading.

thanks Griff, will have a good read whilst busy at work today, all the best, mark
