Reliability of Measurements of Ankle Joint Dorsiflexion Using a Weight-Bearing Lunge Test Obtained in a Clinical Setting


About this study

The aim of this study will be to estimate and compare intra-rater reliability and minimal detectable change (MDC) of maximum ankle dorsiflexion (ADF) in persons with lower extremity injury using a weight-bearing lunge test (WBLT) and three clinical measurement tools: (1) standard goniometer; (2) bubble inclinometer; and (3) digital goniometer. 

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

Inclusion Criteria:

  • Participants will be recruited from the Mayo Clinic Sports Medicine Center. 
  • To be eligible to participate in this study a subject must have sustained an orthopedic injury to the lower extremity and assessment of ankle ADF would be an appropriate component of the patient’s routine physical therapy evaluation. 
  • Eligible participants will present with one or more of the following four clinical diagnoses:
    • Ankle sprain
    • Achilles tendinopathy 
    • Plantar fasciitis 
    • Calf strain

Exclusion Criteria:

  • Persons will be denied admission to the study if weight-bearing is contraindicated.
