Characteristics of how people with neurological or musculoskeletal conditions walk can influence a person's ability to fully participate in their activities of daily life. The movement biomechanics of the lower limb joints involved in successfully navigating the environment affect walking speed, risk of falling, joint and tissue loading, and even the risk for further damage to injured joints.

People who run for fun, fitness, and exercise continue to be at a high risk of experiencing an overuse injury due to their repeated pavement pounding. With the typical runner taking around 1500 steps for every mile of running, small deviations in running biomechanics can increase the risk of injury. Gait laboratory analysis of runners provides a deep dive into the movements and loads at each lower limb joint 200 times a second to aid our understanding of the biomechanics of running injury. Combining these detailed measurements with monitoring during running outside the lab with precision research-grade wearables is bringing further insights.

We must know how accurate and precise our biomechanical measurement tools and devices are to have confidence in the numbers they give us. Tools with a large measurement error or inconsistent readings can lead to incorrect conclusions about the biomechanics of human movement. Determining these psychometric properties for commercially available measurement tools and wearable devices provides needed technical information to help us interpret research findings appropriately.
