Wearing Time of Ankle-Foot Orthoses with Modular Shank Supply in Cerebral Palsy: A Descriptive Analysis in a Clinically Prospective Approach

الملخص EN

Objective.

To date there is only limited knowledge about the wearing time of orthoses.

Ankle-foot orthoses (AFOs) have not been studied with this research question.

Additional influences of the orthotic design as well as weekdays and the weekend are also unknown.

Design.

Monocentric, clinically prospective intervention study.

Patients.

Inclusion of 10 patients with bilateral spastic cerebral palsy.

Methods.

Equipment of all subjects with a dynamic ankle-foot orthosis (DAFO) and modular shank supply (MSS, dynamic elastic shank adaptation or ground reaction AFO).

Integration of temperature sensors for recording the wearing time for a period of 3 months.

Results.

The actual wearing time was below the recommendations on actually worn days as well as the average of the entire study period.

In addition, the actual usage in terms of days and hours was well below the recommendations.

The wearing time showed differences between weekdays and weekend.

Differences between DAFO and MSS were not detectable.

Conclusion.

The actual usage behavior of ankle-foot orthoses differs from the recommendations of the prescriber.

This applies to both DAFOs and modular use with shank supplies.

Environmental factors may have a significant impact on wearing times on weekdays and the weekend.
