is the babinski reflex normal in adults?
4054
The Babinski reflex may be normal in children up to 2 years old. It can sometimes end after 12 months. If the Babinski sign is still noticeable beyond that, it likely indicates neurological problems. The Babinski reflex is never a normal finding in adults.

The spinal cord ends at the level of vertebrae L1–L2, while the subarachnoid space —the compartment that contains cerebrospinal fluid— extends down to the lower border of S2. Lumbar punctures in adults are usually performed between L3–L5 (cauda equina level) in order to avoid damage to the spinal cord.

The Babinski reflex, or plantar reflex, is a foot reflex that happens naturally in babies and young children until they're about 6 months to 2 years old. This reflex is usually tested by doctors by stroking the sole of the foot.

Elicited by a blunt stimulus to the sole of the foot, the normal adult Plantar Reflex presents as a downward flexion of the toes toward the source of the stimulus. Babinski's sign is observed when the Hallux (big toe) exhibits dorsal extension in response to the same plantar stimulation.

In a normal test, your knee will extend and lift your foot a little. A decreased or absent reflex may mean that there is compression in the L2, L3, or L4 region.

Although many people feel normal when not in a “problem” position, some do have a sensation of imbalance. BPPV has often been described as “self-limited” because symptoms often subside or disappear within six months of onset. Symptoms tend to wax and wane. The symptoms can last for days or occasionally months.

It's usually somewhere between 60 and 100 beats per minute for the average adult.

Babinski reflex: A reflex used to determine adequacy of the higher (central) nervous system. ... Most newborn babies and young infants are not neurologically mature, and they therefore show a Babinski reflex. A Babinski reflex in an older child or an adult is abnormal and is a sign of a problem in the brain or spinal cord.

Healthy adults should do flexibility exercises (stretches, yoga, or tai chi) for all major muscle-tendon groups-neck, shoulders, chest, trunk, lower back, hips, legs, and ankles-at least two to three times a week. For optimal results, you should spend a total of 60 seconds on each stretching exercise.

Reflexes do slow with age. Physical changes in nerve fibers slow the speed of conduction. ... But the effect of age on reflexes and reaction time varies greatly from person to person. You can actually slow down—even reverse—the effects of aging by staying physically active.

The good news is, in most cases, this reflex is normal and just another part of pregnancy. It's important to note that fetal hiccups are, in general, considered a good sign. After week 32, though, it's less common to experience fetal hiccups every day.

Normal vital sign ranges for the average healthy adult while resting are: Blood pressure: 90/60 mm Hg to 120/80 mm Hg. Breathing: 12 to 18 breaths per minute. Pulse: 60 to 100 beats per minute.

In normal adults a resting heart rate of 60-80 is common. Deconditioning can lead to faster rates while conditioned athletes can have heart rates in the 40-60 range.

While a heart rate is considered normal if the rate is between 60 and 100 beats per minute, most healthy relaxed adults have a resting heart rate below 90 beats per minute.

Multiple sclerosis (MS): While weak reflexes are more common with MS, this condition can lead to severe muscle spasms. During a reflex test, such spasms might occur and lead to a diagnosis of brisk reflexes. With MS, you may have problems with gait and overall movement, too.

When assessing the plantar reflex, observe for plantar flexion where the toes curl toward the sole of the foot. The Babinski response is dorsiflexion of the great toe and fanning of the other toes when eliciting the plantar reflex. ... Fanning of the toes occurs with a positive Babinski.

Results. NCV tests can measure the speed and strength of nerve signals. Nerve conduction velocity between 50 to 60 meters per second is considered normal. A damaged nerve may send a slower and weaker signal than a healthy one.
