Retul Motion Analysis Case Study – Foot/Ankle
I recently had a client with significant foot/ankle orthopedic history. Needless to say the foot and ankle no longer move much. This of course had implications to the fit of his bike. His first visit I got him close to what I thought was pretty close to good. His task was to ride his bike for 2-3wks to get used to that position. I then had him come in for motion analysis with Retul. Upon closer evaluation, we found that he still had quite a bit of reaching through the bottom of his pedal-stroke which resulted in rocking of the hips. The cues that I used were ankle range of motion, knee lateral travel and lateral hip travel measures. These are all measures that are difficult to do by eye (I have been doing this for almost 20 years) and can’t be fully assessed via static measures. I lowered his saddle ~3mm. The results were pretty cool. Ankle, knee and hip motions made significant improvements and came much closer to values of the normal side. The Retul device is very helpful for me in this type of case. Normalization of “symmetry” on a case such as this will be and should be impossible due to the orthopedic history. HOWEVER,….minimization of irregular motion is possible and will have a positive signicance in this person’s capability of riding his bicycle well! Have a great weekend!
