Influence of ankle dorsiflexion range of motion on heel-rise time during gait.
Min-Hyeok Kang
PMID 29765182WHAT IT FOUND
Weight-bearing ankle dorsiflexion was related to heel-rise time during gait in 30 healthy young adults.
Passive non-weight-bearing dorsiflexion was not related.
Key findings
01Weight-bearing ankle dorsiflexion range of motion was significantly correlated with heel-rise time.
02Passive non-weight-bearing ankle dorsiflexion range of motion was not significantly correlated with heel-rise time.
03Weight-bearing ankle dorsiflexion range of motion was significantly correlated with ankle dorsiflexion at heel-rise, while passive non-weight-bearing range was not.

What it does not show
Only 30 healthy young adults were studied, so the results may not apply to older adults or people with foot, ankle, or neurological conditions. The study tested relationships between ankle dorsiflexion measurements and heel-rise timing, not whether treatment changes either. Only ankle dorsiflexion range of motion was considered, and foot and ankle alignment variables were not included.
Declared interests
The work was supported by International University of Korea's research fund in 2018. The authors declared no conflicts of interest.
The easy way to misread this
Do not conclude that increasing ankle dorsiflexion will change heel-rise timing or prevent injury. The study measured correlation in healthy young adults and did not test an intervention.
