Ambulatory Function and Perception of Confidence in Persons with Stroke with a Custom-Made Hinged versus a Standard Ankle Foot Orthosis

الملخص EN

Objective.

The aim was to compare walking with an individually designed dynamic hinged ankle foot orthosis (DAFO) and a standard carbon composite ankle foot orthosis (C-AFO).

Methods.

Twelve participants, mean age 56 years (range 26–72), with hemiparesis due to stroke were included in the study.

During the six-minute walk test (6MW), walking velocity, the Physiological Cost Index (PCI), and the degree of experienced exertion were measured with a DAFO and C-AFO, respectively, followed by a Stairs Test velocity and perceived confidence was rated.

Results.

The mean differences in favor for the DAFO were in 6MW 24.3 m (95% confidence interval [CI] 4.90, 43.76), PCI −0.09 beats/m (95% CI −0.27, 0.95), velocity 0.04 m/s (95% CI −0.01, 0.097), and in the Stairs Test −11.8 s (95% CI −19.05, −4.48).

All participants except one perceived the degree of experienced exertion lower and felt more confident when walking with the DAFO.

Conclusions.

Wearing a DAFO resulted in longer walking distance and faster stair climbing compared to walking with a C-AFO.

Eleven of twelve participants felt more confident with the DAFO, which may be more important than speed and distance and the most important reason for prescribing an AFO.
