The plantar fascia (PF) extends over the calcaneal bone with a thin band corresponding to the calcaneal periosteum, continuing as the paratenon of the Achilles tendon.The triceps surae complex, serving as the main extensor and propulsion system of the foot, involves the Achilles tendon, posterior part of the calcaneus, and Plantar Aponeurosis, all integrated with the fibrous skeleton of the triceps surae. Plantar fasciitis, a prevalent musculoskeletal condition affecting individuals of various ages and activity levels (Hye Chang Rhim), is a primary cause of heel pain in adults. Studies have identified the superior efficacy of stretching protocols targeting the Achilles tendon and/or plantar fascia compared to alternative treatments. However, the limitations of traditional approaches become apparent when considering the intricate biomechanics of the foot and ankle. Conventional calf stretches often prove inadequate for addressing its specific lengthening requirements. While contemporary methods like PF-Specific Stretching integrate plantar fascia and calf stretches, their reliance on individual upper extremity strength introduces potential limitations. Therefore, although the exact effect of stretching on the biomechanical properties of the plantar fascia is not known, it will be aimed to determine whether an instrument aid to be designed will have an effect and which method is more effective. In this way, it is planned to guide clinicians in the rehabilitation of possible pathologies specific to the plantar fascia in clinical practice. Myotonometry is a convenient method to assess the stiffness of the plantar fascia because it is cheap, simple and fast. Previous studies have shown that MyotonPRO can reliably assess the stiffness of the plantar fascia. Although the exact effect of stretching on the biomechanical properties of the plantar fascia is not known, it will be determined whether stretching with an instrument to be designed will have an effect and which method is more effective with or without an instrument.
