Design and Reliability of a Novel Heel Rise Test Measuring Device for Plantarflexion Endurance

الملخص EN

Background.

Plantarflexion results from the combined action of the soleus and gastrocnemius muscles in the calf.

The heel rise test is commonly used to test calf muscle endurance, function, and performance by a wide variety of professionals; however, no uniform description of the test is available.

This paper aims to document the construction and reliability of a novel heel rise test device and measurement protocol that is suitable for the needs of most individuals.

Methods.

This device was constructed from compact and lightweight materials and is fully adjustable, enabling the testing of a wide variety of individuals.

It is easy to assemble and disassemble, ensuring that it is portable for use in different settings.

Findings.

We tested reliability on 40 participants, finding excellent interrater reliability (ICC2,1 0.97, 95% CI: 0.94 to 0.98).

Limits of agreement were less than two repetitions in 90% of cases and the Bland-Altman plot showed no bias.

Interpretation.

We have designed a novel, standardized, simple, and reliable device and measurement protocol for the heel rise test which can be used by researchers and clinicians in a variety of settings.
