The diagnosis of tarsal tunnel syndrome is made through a comprehensive evaluation by a specialist physician. This process primarily includes a physical examination. During the physical examination, findings such as tenderness over the nerve when weight-bearing, the presence of flatfoot, painful ankle movements, and pain elicited during a compression test applied to the tarsal tunnel region are evaluated. To support the diagnosis, various imaging methods are utilized. A weight-bearing foot X-ray can assess bone structures, while MRI (magnetic resonance imaging) may be used to visualize soft tissue problems. An electromyography (EMG) test is performed to evaluate nerve functions. This test contributes to the diagnosis by detecting a decrease in nerve activity in the affected area. Furthermore, the patient's history of symptoms is an important contributing factor in the diagnostic process.
