Association Between Altered Hip Extension and Kinetic Gait Variables.
Elizabeth C Wonsetler, Ellie L Miller, Katherine L Huey and 2 others
PMID 29342022WHAT IT FOUND
In 10 healthy adults, changing cadence while keeping walking speed constant altered hip extension and was linked to changes in propulsion and ankle work.
This is a treadmill method, not evidence for impaired patients.
Key findings
01Changing cadence while holding speed constant altered step length and hip extension in healthy adults.
02Changes in hip extension were significantly correlated with changes in propulsive impulse, peak ankle power, and ankle plantarflexion work.

What it does not show
Ten healthy adults from a convenience sample, so it does not represent patients. The method was not tested in people with neurologic gait impairment. Kinetic calculations rely on anthropometric assumptions, and the unequal sex distribution may affect them. Each trial lasted 30 seconds and the number of gait cycles was not standardized.
Declared interests
The authors declared no conflicts of interest. The paper is listed as supported by NIH extramural and U.S. government non-PHS research support.
The easy way to misread this
Do not read this as evidence that cadence training improves gait in stroke or spinal cord injury. The study used 10 healthy adults and did not test an impaired population.
