TI  - The effect of custom-made braces for the ankle and hindfoot on ankle and foot 
      kinematics and ground reaction forces.
PG  - 130-5
AB  - OBJECTIVE: To assess the effects on gait of custom-made polypropylene orthoses: 
      ankle-foot orthosis (AFO), rigid hindfoot orthosis (HFO-R), and articulated 
      hindfoot orthosis (HFO-A). DESIGN: Experimental assessment. SETTING: 
      Institutional practice, motion analysis laboratory. PARTICIPANTS: Twenty 
      asymptomatic normative subjects. INTERVENTIONS: Not applicable. MAIN OUTCOME 
      MEASURES: Three-dimensional kinematics, ground reaction force, and time-related 
      factors in 4 conditions: shoe only, and shod with the AFO, HFO-R, and HFO-A. 
      RESULTS: The AFO and HFO-R limited sagittal and coronal plane ankle-hindfoot 
      motion. The HFO-A limited hindfoot coronal motion while allowing normal sagittal 
      motion. At the midfoot, the AFO and HFO-A limited transverse motion, but the 
      HFO-A also limited sagittal and coronal motion. Use of the HFO-R resulted in 
      exaggerated midfoot sagittal and coronal motion. Braces that limited motion to a 
      greater degree were associated with more atypical kinetic variables, indicative 
      of less dynamic gait. The HFO-A resulted in ground reaction forces most similar 
      to unbraced conditions. CONCLUSIONS: Alteration in gait was affected by orthosis 
      design. Orthoses with a rigid component crossing a joint restricted motion at 
      that joint, but potentially compromised typical gait kinetic factors. For 
      immobilizing the hindfoot, the HFO-A may be more comfortable and still provide 
      more stability than the HFO-R or AFO.
