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 test is performed using an electric stimulator, which gives usually a square-wave current of short duration and small amplitude (higher stimulations might involve alpha fibers, causing an F-wave, compromising the results), and an EMG set, to record the muscle response.fter about 5 days in zero gravity, for instance in orbit around Earth, the h-reflex diminishes significantly. It is generally assumed that this is due to a marked reduction in the excitability of the spinal cord in zero gravity.
