The heel-raise test for ankle plantarflexor strength: a scoping review and meta-analysis of studies providing norms

[Purpose] The heel-raise test (HRT) is sometimes used to quantify ankle plantarflexion strength. However, descriptions of the test vary and normative values are limited. This paper, therefore was generated to summarize procedures and provide normative values for the HRT in a younger and older age group of adults. [Methods] Electronic and hand searches were conducted to identify relevant literature. Meta-analysis was used to provide norms. [Results] Among 439 nonduplicative articles identified, 13 qualifying articles were ultimately included. Procedures for the HRT described in the studies varied considerably. The mean number of HRT repetitions was 28.7 for adults with a mean age less than 40 years and 11.8 for adults with a mean age greater than 60 years. [Conclusion] This study provides information on HRT performance and norms derived with them for younger and older adults.
