Investigation of Myotonometer Reliability in Evaluation of Plantar Fascia Biomechanical Properties

Investigation of Myotonometer Reliability in Evaluation of Plantar Fascia Biomechanical Properties in Individuals With Diabetes

The study aims to examine the intra-rater, inter-rater, and inter-session reliability of MyotonPRO in measuring plantar fascia mechanical properties in adults with diabetes.

Therefore, changes occur in standing weight-bearing points, loading zones, and gait biomechanics. The thickened plantar fascia increases the risk of developing diabetic foot with increased peak-plantar pressure, and therefore, plantar fasciitis is more common in individuals with diabetes than in healthy individuals. The myotonometer studies showed that chronic diabetes history increases dynamic stiffness, which is one of the mechanical properties of the plantar fascia, and that as the severity of the disease increases, fascial stiffness also increases. The aim of the study is to examine the intra-rater, inter-rater, and inter-session reliability of MyotonPRO in measuring plantar fascia mechanical properties in adults with diabetes.
