Thread: Biomechanic Software

Started 1 month ago by tennillef
Hi everyone, Hope that those who are in the warm states are enjoying the lovely weather! I am looking for some suggestions of biomech programs we could look at installing at our new clinic which people believe work well and would recommend. Kindest regards and thanks for your help!

Alright heres what I´m Thinking.. 1st we must think of newton ´to every action there must be an equal and opposite reaction´ When the foot comes incontact with the stiff orthotic there will be more soft tissue compression (intial reaction), as the soft tissue expands ( reaction) the less orthotic changes shape the soft tissue will begin to move bone position within the foot and ...

So Ive just tried a little experiment. Hand slap on a table v´s hand slap on a pt treatment couch. Ive felt much more impact from the table on my hand so therefore I lost less energy when comming to contact with the harder table. So this should represent the two different devices so therefore I was very wrong sorry for being dense.

Just learned something new today from a discussion on Biomech-l. The proper term for the time derivative of acceleration is "jerk". The order of derivation of position is as follows: 1st derivative: velocity 2nd derivative: acceleration 3rd derivative: jerk 4th derivative: snap 5th derivative: crackle 6th derivative: pop Here is the discussion: Quote: Thanks to everyone who responded. Everyone agreed that jerk is the...

Inverted Technique
Published (2009-12-07 06:10:00)
Phil Yes good reply thanks, I had an idea that the forefoot was allowed to plantarflex. So I guess the clinician must evaluate whether or not the foot is suitable for this type of orthosis. I.E> if the midtarsal joints / met cuneiform joints are very stiff then this might not be a good orthosis to use. Years ago I did have a paper describing how to make these devices but it seems to have disappeared into the memory void of one of my...

This method gives you separate control of medial arch shape and...

Postgrad Biomechanics Course
Published (2009-12-11 03:14:00)
Hi Alex, Check out this thread I did a while back - basically a list of the potential courses you may be interested in. Not sure how up to date it is or if the links on it still work but may give you some ideas and contact details. I'm pretty sure UWIC (Cardiff) do a week long residential type delivery - alot of the others are 5-6 weekends over the academic year usually Ian
