What is normal DTR?

1+ = a slight but definitely present response; may or may not be normal. 2+ = a brisk response; normal. 3+ = a very brisk response; may or may not be normal. 4+ = a tap elicits a repeating reflex (clonus); always abnormal.

What is DTR testing?

The deep tendon reflex (DTR) examination is part of the neurologic exam. There are five primary deep tendon reflexes: bicep, brachioradialis, triceps, patellar, and ankle. Each reflex corresponds to a particular root and muscle and will evaluate the integrity of the root and associated nerve.

What does brisk deep tendon reflexes mean?

What are the symptoms of brisk reflexes? During a reflex test, your muscle shortens (contracts) in response to deep tendon taps from the reflex hammer. Brisk reflexes describe an instance where the muscles contract more strongly or more times than normal.

What is a tendon reflex?

Tendon reflexes are single synapse reflexes. A rapid stretch of the muscle stimulates the muscle spindles and this message is conveyed via the sensory root to the spinal cord at the segmental level of the muscle stimulated.

What is DTR OB?

Abbreviation for deep tendon reflex.

What is DTR in pregnancy?

Adopted: 09/05. Deep Tendon Reflexes (DTR) Deep tendon reflexes, more properly referred to as muscle stretch reflexes, are an integral part of the neurological examination. A stretch reflex is an involuntary reaction of a muscle to being passively stretched by percussion of the tendon.

What nerve root is the patellar reflex?

The patellar reflex is a deep tendon reflex, mediated by the spinal nerves from the levels L2, L3, and L4 in the spinal cord, predominantly in the root L4.

What does DTR stand for in data terminal?

Data Terminal Ready ( DTR) is a control signal in RS-232 serial communications, transmitted from data terminal equipment (DTE), such as a computer, to data communications equipment (DCE), for example a modem, to indicate that the terminal is ready for communications and the modem may initiate a communications channel.

Where is the DTR signal on a DE-9 serial port?

The DTR signal is present on pin 20 of the 22-wire RS-232 interface using a DB-25 connector, and on pin 4 of a newer DE-9 serial port. The signal is asserted (logic “1”) by raising the voltage of the pin from negative to positive.

When do you use DTR for flow control?

Use for flow control. When DTR is used for flow control, it manages the flow of data from the printer to the computer. However, because during printing, the bulk of the data is from the computer to the printer, the importance of flow control in the opposite direction is minimal.

How is DTR used in a serial mouse?

On some hardware the DTR line (along with RTS) may be used to provide power. The most notable example of this is a serial mouse. The DE-9 serial port on the PC does not provide any dedicated power source. The mouse driver holds the DTR and RTS lines high at all times so that the device has a source of power.
