Dr. Hutchinson’s Knee Exam
Today I found an interesting Knee Exam series on You tube.
Dr. Mark Hutchinson’s Knee Exam is a combined project of the University of British Columbia (UBC), the University of Illinois, Chicago (UIC) and the Norwegian University of Sport Sciences, Oslo.
27 short films show a great and complete knee examination!

Supination Resistance Testing
One of the most common problems podiatrists need to resolve with orthotic therapy is a pronation momentum that – because of it’s amount; timing or duration – is responsible for injury. Resisting this pronation momentum by creating a rotational equilibrium (in case of hinge type subtalar joint) is one of the important aspects of orthotic therapy. To determine how much force the orthotic device needs to exert to create enough ‘orthotic reaction force’ to establish this rotational equilibrium, one can use the clinical method described by K. Kirby to determine the location of the subtalar joint axis in the transverse plane. When this axis is medially deviated, the area on the plantar surface of the foot where force can be exerted to supinate the foot will be very small and thus a lot of force will be needed. The clinical test to determine the amount of force is the supination resistance test. This test can be a useful clinical tool to assist the podiatrist in the decision making when prescribing foot orthosis.

Finally somebody puts his foot down – or is it both feet!
Yesterday, Craig Payne started a post on the podiatry arena, stating that it is time to stop using both feet of a subject when doing research (when not comparing left with right). This ‘one foot or 2 feet’-discussion is being a unsettled issue for quite some time now.
Some key-articles are:
(1) Menz HB. Two feet, or one person? Problems associated with statistical analysis of paired data in foot and ankle medicine. The Foot. 2004;14:2-5.
(2) SUTTON AJ, MUIR KR, JONES AC. Two knees or one person: data analysis strategies for paired joints or organs. Ann Rheum Dis. 1997;56:401-402.
Menz pointed already to the possibility of “spurious findings” but still the basic reason why researchers want to use both feet, is probably due to a lack of sample size…
When looking at research done in other disciplines (like orthopeadics, opthalmology, biomechanics, …) they use persons.

Rock your anatomical braincells!
On my conquest to make anatomy more digestible (see my frustration), and in my series of clinical anatomy 101, i’d like to introduce a fantastic Anatomical remix (Vol 3): The Foot. It’s based on the Auckland’s DVD atlas of human anatomy part 2: The Lower Extremity (Lippincott Williams & Wilkins)
Also available and interesting for you I’pod’s out there:
Anatomical Remix Vol 1: Hip’n'Pelvis
Anatomical Remix Vol 2: The Knee
Podrunner
For all ya start-to-runner’s out there, some nice nonstop mixes with a fixed-BPM for runners.
DJ Steve Boyett produces three of the world’s most popular music podcasts: Podrunner and Podrunner: Intervals (workout music mixes), and Groovelectric (dance music mixes of what he calls New Old Funk).
Big brother
Proud as can be, our Mattias is being the best big brother anyone can ask for.
Loving, Caring, Holding, Kissing
Cute innit?
Bramboraky
This one is going to make my mum SOOOOO jealous!
After a hard days work, a good old Bramborak or potato pancake is another goody I got to eat. Combined with a cold one it is a perfect closing of the day. here in combination with the classical tomato/onion/vinegar salad.
recipe can be found here
cheers!
Hopdovody and pork chop in paprika sauce
Another Food post! When you look at the picture, you can see the typical HOPDOVODY (translated as ‘jump in water’). They are actually made on the same base as when making a bread, only – instead of baking the dough, you make small balls with a spoon or use a hopdovody-tool and drop the dough balls in boiling water. Together with the pork chops and paprika sauce, a filling great meal! Mother in law tip: the balls sink to the bottom of your cooking pot, when they float on top, they are ready!
chlebicky – (pronounced: chlebeechky)
In our food series this week a few words on the famous czech chlebicky! The opened faced cold sandwiches with an astonisching artistically arranged topping like ham, salami, hard-boiled egg, lettuce, cheese, tomato, mayo, mustard, pickles and many more, spoils your tastebuds!!!! Accompanied by a giant pot of tea with lemon and sugar makes the daily stress go away with every bite/sip you take.
