A Perfect Bike Fit Starts With the Correct Crank Arm Length

Having performed thousands of bike fits, I now believe that the bicycle’s crank arm length is the most important factor when performing a bike fit. Every other anatomical dimension and joint angle is based upon the length of the crank arms; therefore, this is the first factor to address when performing a bike fit.

Pregnancy Part 1: Is Walking Adequate Fitness During Pregnancy?

There is no question that walking is generally a good form of exercise. However, it is not always appropriate during all phases of pregnancy, nor does it adequately prepare a woman for delivery or the fourth ‘Tornado’ Trimester. Long gone are the days of no lifting and putting your feet up during pregnancy. Pregnancy is the time to ‘train’ for a postnatal marathon that will last several years in a sleep-deprived state.

Gait and Balance Academy: How Do We Use Gait Analysis to Measure Walking Consistency?

Have you ever asked yourself this simple question: why do we measure and analyze gait? Overall, the answers will revolve around the same ideas: to gauge the functional status of a person; to follow-up the natural history of a disease; to determine immediate or long-term treatment requirement and effects.

Foot Drop: A Primer

Foot drop, a complex condition that can have a significant impact on independent ambulation, can have many causes. Treatment options vary by cause. These authors provide a review of the condition from etiology through treatment. Foot drop (also known as steppage gait) is an inability to lift the forefoot due to the weakness of dorsiflexors of the foot. This, in turn, can lead to an unsafe antalgic gait, potentially resulting in falls.

Expanding Our Understanding of Chronic Ankle Instability

Research is showing that it’s not “just an ankle sprain,” but rather the first step on a perilous journey to physical instability and lower quality of life. The clinical presentation of chronic ankle instability (CAI) has been defined as the perceived or subjective instability with feelings of giving way, pain, and recurrent sprains. Continue reading
