Some research indicates that nerve conduction tests will be normal in at least 50% of the cases. Given the unclear role of electrodiagnostics in the diagnosis of tarsal tunnel syndrome, efforts have been made in the medical literature to determine which nerve conduction studies are most sensitive and specific for tibial mononeuropathy at the level of the tarsal tunnel. An evidence-based practice topic put forth by the professional organization, the American Association of Neuromuscular & Electrodiagnostic Medicine has determined that Level C, Class III evidence exists for the use of tibial motor nerve conduction studies, medial and lateral plantar mixed nerve conduction studies, and medial and lateral plantar sensory nerve conduction studies. The role of needle electromyography remains less defined.Tarsal tunnel syndrome (TTS) is most closely related to carpal tunnel syndrome (CTS). However, the commonality to its counterpart is much less or even rare in prevalence Studies have found that patients with rheumatoid arthritis (RA) show signs of distal limb neuropathy. The posterior tibial nerve serves victim to peripheral neuropathy and often show signs of TTS amongst RA patients. Therefore, TTS is a common discovery found in the autoimmune disorder of rheumatoid arthritis

Prevention
The exact cause of tarsal tunnel syndrome (TTS) can vary from patient to patient. However the same result is true for all patients, the compression of the posterior tibial nerve and it branches as it travels around the medial malleolus causes pain and irritation for the patient.
In the workplace TTS is considered a musculoskeletal disorder and accounts for 1.8 million cases a year, which accumulates to about $15–$20 billion a year New studies indicate an occurrence of TTS in sports placing high loads on the ankle joint (3). This can be seen in figure 1. TTS occurs more dominantly in active adults, with a higher pervasiveness among women. Active adults that experience more jumping and landing on the ankle joint are more susceptible (see figure 2). Though athletics and sport are correlations, cases are individualistically assessed because of the oddity. Athletic activities
The athletic population tends to put themselves at greater risk of TTS due to the participation in sports that involve the lower extremities. Strenuous activities involved in athletic activities put extra strain on the ankle and therefore can lead to the compression of the tibial nerve. Activities that especially involve sprinting and jumping have a greater risk of developing TTS. This is due to the ankle being put in eversion, inversion, and plantarflexion at high velocities. Examples of sports that can lead to TTS include basketball, track, soccer, lacrosse, snowboarding, and volleyball. Participation in these sports should be done cautiously due to the high risk of developing TTS. However athletes will tend to continue to participate in these activities therefore proper stretching, especially in lower extremities,  prior to participation can assist in the prevention of developing TTS.
