Fig 4 Nine force parameter peaks (F1–F9) and their chronology (T1–T9) were assessed.28 Archives of Physical Medicine and Rehabilitation 2006 87, 130-135DOI: (10.1016/j.apmr.2005.08.120) Copyright © 2006 American Congress of Rehabilitation Medicine and the American Academy of Physical Medicine and Rehabilitation Terms and Conditions
Fig 5 Hindfoot motion in the sagittal plane. The HFO-A allowed more normal sagittal motion than the AFO and HFO-R. Values are mean ± standard deviation (SD).
