Question: How is a VEP(Visual Evoked Potential) test done?

Answer: A CPAP machine provides air at a constant pressure delivered to the person through a tube and mask. This keeps the airway open so uninterrupted breathing is maintained during sleep which allows the person to get restful sleep.   Click here for information on CPAP therapy and machines. 

Answer:  While you are laying in a comfortable position on the exam table, several small recording wires will be taped to your hand or foot.  A small electric simulator will be placed on the skin close to the wires, and an electrical impulse will be given.  The signal, after traveling down the nerve, is recorded by the electrode wires and printed on a graph. It may tingle or make your muscles twitch momentarily, but this is not harmful or painful.​

Question: What is a TENS unit and how does it help me with my pain?

Question: What is a Home Sleep Test (HST)  and how do I record my sleep functions using the Alice NightOne appliance?

Question: How is an EMG (Electromyography) test done?

Answer: A Home Sleep Test (HST) is a non-invasive test that records your biological functions while you sleep in the comfort of your own home.  The test uses a mobile appliance that you bring home with you from your doctor's office and put on yourself prior to going to sleep.  You bring the appliance back the following day to your doctor's office so that your healthcare provider trained in Sleep Medicine can identify sleep issues and develop a plan of action.  Click here for an instructional video on the Alice NightOne Home Sleep Test.

Question: Is NCV/EMG testing painful?

Answer:  While you are laying in a comfortable position on the exam table, small sensors called electrodes are attached to your head. Activity of the brain is picked up by the electrodes and is shown as lines or waves on paper or on the computer screen.​  This test is not painful.

Question: How is a NCV (Nerve Conduction Velocity) test done?

Answer:  A TENS (Transcutaneous Electrical Nerve Stimulation) unit is a small electrical appliance that is used to treat nerve related pain by sending tiny electrical pulses along the surface of the skin.  Your healthcare provider may advise you to use this device to treat both acute and chronic pain conditions.  Click here for more information about the TENS unit.

Answer:   Fluoroscopy is a special form of X-ray that produces real-time video images, as opposed to pictures on film, making it possible to see internal organs and joints in motion. A lumbar puncture is a fluoroscopic procedure used to collect and look at the cerebrospinal fluid (CSF) surrounding the brain and spinal cord.  Click here for more on Lumbar Punctures.

Answer:  There may be some discomfort when the needle is inserted like a small pinch or you may feel a brief tingling sensation.  There is no need for a sedative or anesthetics. Being calm with relaxed muscles will help lessen any possible discomfort.  Once the test is underway, most people find it easier than they expected.  You may experience some small areas of muscular soreness, but most people have no difficulty returning to their regular daily activities, including work.

Answer:  A Sleep Study is a non-invasive test that occurs while you are sleeping to help diagnose sleep issues.  You spend the night at a Sleep Facility with electrodes taped to your body so that a technician can record your biological functions such as heart rate, movement and eye motions while you sleep.  The results of this test help a healthcare provider trained in Sleep Medicine to identify sleep issues and develop a plan of action.  Click here for more information about what to expect at the Sleep Center.
