Syphilis is a sexually transmitted infection (STI) caused by bacteria. Syphilis is spread through direct contact with the sores of an infected person. This usually happens through sexual activity, especially unprotected sex. It can also spread through sharing needles or contact with the blood of an infected person. If you are pregnant, you can give syphilis to your baby.
Simultaneous red reflex test [edit]. The simultaneous red reflex test is used to view both reflexes at the same time. This can help determine if the patient has normal ocular alignment. In order to perform this test the patient and physician are normally approximately 2 to 3 feet away from each other.imultaneous red reflex test [edit].

The H-reflex is most commonly tested by electrical stimulation of the tibial nerve, with recordings from the gastrocnemius/soleus muscle complex (i.e., the triceps surae) (Figure 6). Therefore, this response utilizes the same neural pathway as the ankle jerk reflex.ince the H-reflex is mediated primarily over the S1 nerve root (just like the ankle jerk reflex), it is a sensitive test for S1 radiculopathy. However, once the reflex arc has been damaged, it often does not return to normal (making the test less useful in investigating the question of recurrent radiculopathy).
