Correlação da amplitude de movimento da articulação talocrural e do desempenho do músculo tríceps sural durante o Teste de Elevação do Calcanhar cadenciado externamente

Abstract

Introduction: The ankle and foot perform essential functions during locomotion, therefore, injuries that affect these structures may limit mobility. Functional clinical tests such as the Heel Rise Test (HRT) further the identification of muscle-tendon dysfunction, however, it is still unclear whether joint amplitude can influence the performance of this joint during its evaluation. Objectives: To correlate ankle range of motion with sural triceps performance during externally cadenced HRT (HRTEC). Methodology: Individuals of both sexes, aged 20 to 59 years, with body mass index between 18.5 and 29.9 kg/m², with absence of peripheral vascular diseases and/or musculoskeletal diseases were recruited for the study. After the collection of personal and anthropometric data, the International Physical Activity Questionnaire (IPAQ), the ankle-brachial index, the active and functional range of motion (ROM) was performed. For the HRTEC we used an external cadence of 1 elevation/second, using a simple metronome for control. All the assessments were performed by a single trained evaluator. Results: A total of 73 individuals were included, 45% men, with median age of 31 years, height of 1.60m and weight of 70.3kg. The total sample presented 52 [40.5-69.5] elevations, with a difference between men and women (59 [48-83.5] vs 47 [40-58.5], p = 0.004 respectively), with lower functional ROM in men (52 [48-58] vs 60 [58-62], p <0.0001 respectively). There was a low correlation between performance versus IPAQ (r = 0.32, p = 0.05), low correlation between performance and functional ROM (r = -0.15, p = 0.19), and no correlation between IPAQ and functional ROM, (r = -0.71, p> 0.05). Conclusion: The range of motion of the talocrural joint does not influence the HRTEC performance in the healthy population without associated diseases.
