Comparison between actual ambulatory independence levels after alternate gait training using a knee-ankle-foot orthosis and independence levels predicted based on Niki’s independence prediction method.

Abstract

Purpose : The purpose of this study was to investigate whether providing alternate gait training using a knee-ankle-foot orthosis with an oil damper ankle hinge （KAFO-OD） results in therapeutic effects surpassing the outcomes predicted using previously reported prognostic method for ambulatory independence.

Methods : Forty-three stroke patients underwent alternate gait training using a KAFO-OD at a convalescent rehabilitation ward. We retrospectively investigated each patient’s predicted ambulatory independence level based on Niki’s independence prediction method, and compared them with the patient’s actual independence level at discharge.

Results : According to Niki's prediction indicators, three patients were predicted to achieve ambulatory independence, 28 were predicted to be dependent, and prediction was not possible for the remaining 12 patients. However, assessment at discharge showed that 27 patients achieved ambulatory independence, while 16 remained dependent.

Conclusion : Providing alternate gait training using a KAFO-OD for stroke patients may improve ambulatory independence levels at discharge.
