Top 30 Doctor insights on: Hyperactive Deep Tendon Reflexes Hyperactive Deep Tendon Reflexes (Overview). Hyperactive deep tendon reflexes are a clinical finding in which the reflexes of the major joints in the body are tested by a physician (such as tapping beneath the knee) and are found to be produce more of a reflex response in speed or amount of movement.et help from a doctor now ›. Deep tendon reflex: Dtr or deep tendon reflex is a test done on physical exam to evaluate specific nerve function. Certain nerves like cervical and lumber spinal nerves control certain reflexes and when absent can indicate a problem with that nerve.

- The calcaneal reflex or Achilles or ankle-jerk reflex is a stretch reflex that assesses the nervous tissue between (and including) the first two sacral segments. It can be elicited by sharply tapping the calcaneal tendon (just above the ankle) with the base of a Taylor hammer.Repeat with the other limb.f the spinal cord is damaged, then reflex tests can help determine the area of injury. For example, motor nerves above an injured area may be unaffected, whereas motor nerves at or below the damaged area may be unable to perform the usual reflex activities.

- 10 most extreme places on Earth. A stretch reflex, also referred to as a deep tendon reflex or myotatic stretch reflex, is a physical response to the extension of a muscle. In essence, it is a process that causes a contraction, thereby stopping a stretch.efore a workout, take time to gently and slowly stretch the muscles in order to help prevent any muscle damage. Runners who don't stretch adequately before a workout run the risk of muscle tears or other damage. Tapping the petellar tendon with a reflex hammer will trigger the knee jerk reflex.

- Hyperreflexia is defined as overactive or overresponsive reflexes. Examples of this can include twitching or spastic tendencies, which are indicative of upper motor neuron disease as well as the lessening or loss of control ordinarily exerted by higher brain centers of lower neural pathways (disinhibition).

Flexor digitorum profundus muscle Flexor digitorum profundus muscle. In human anatomy, the flexor digitorum profundus (FDP, Latin for deep bender of the fingers) is a muscle in the forearm that flexes the fingers (also known as digits). It is considered an extrinsic hand muscle because it acts on the hand while its muscle belly is located in the forearm.

- The knee-jerk reflex involves a sudden kicking movement of your lower leg after the tendon just below your kneecap has been tapped. Doctors often trigger this reflex to test the function of your nervous system. If the reaction is exaggerated or absent, it may indicate a damage to the central nervous system.

Understanding the Stretch Reflex (or Myotatic Reflex) The stretch reflex; which is also often called the myotatic reflex, knee-jerk reflex, or deep tendon reflex, is a pre-programmed response by the body to a stretch stimulus in the muscle.he stretch reflex is very important in posture. It helps maintain proper posturing because a slight lean to either side causes a stretch in the spinal, hip and leg muscles to the other side, which is quickly countered by the stretch reflex. This is a constant process of adjusting and maintaining.

Chapter 8 - Reflex evaluation Classically, destruction of the major portion of the cerebellar hemispheres in humans is associated with pendular deep-tendon reflexes. The reflexes are poorly checked so that when testing the patellar reflex, for example, the leg may swing to-and-fro (like a pendulum).

Reflex Tests Reflex tests are performed as part of a neurological exam, either a mini-exam done to quickly confirm integrity of the spinal cord, or a more complete exam performed to diagnose the presence and location of spinal cord injury or neuromuscular disease. Deep tendon reflexes are responses to muscle stretch.

reflex A positive reaction is a sharp contraction of the muscle of which the tendon is part. The patellar reflex is the best known of these reflexes. Absence indicates a defect in the reflex arc, an exaggerated response suggests an upper motor neuron lesion.Called also myotactic reflex. tonic reflex. see tonic neck response. positive reaction is a sharp contraction of the muscle of which the tendon is part.
