What could cause me to have no reflex reactions in the soles of my feet, ankles or calves?

What could cause me to have no reflex reactions in the soles of my feet, ankles or calves?

Many possibilities: Reflexes vary from person to person, but also from exam to exam. Repeated testing during a visit can vary for several reasons (position of the leg, how relaxed you are, where the stimulating "tap" is given, etc.). Later in life reflexes may diminish or disappear. Some nerve disorders reduce or eliminate them. ...Read more

I just had an EMG test done and the doctor that performed it first checked my reflex in my ankle and said it was reduced but my EMG was normal. How?

I just had an EMG test done and the doctor that performed it first checked my reflex in my ankle and said it was reduced but my EMG was normal. How?

Abnormal reflexes: An EMG measures muscles; reflexes measure nerve activity. Hypothyroidisnm can cause slowed reflexes. Nerve damage at age 20, due to a disease of nerves, such as a neuropathy, is unlikely, but can be checked for by your neurologist. That test is a nerve conduction study (NCS). If NSC is abnormal then you will need more studies to (hopefully) determine the cause. ...Read more

Nerve Conduction Study normal but neurologist noted that right ankle reflex was reduced. How can that be if the nerve study was normal?

Nerve Conduction Study normal but neurologist noted that right ankle reflex was reduced. How can that be if the nerve study was normal?

H reflex: You are probably referring to the H reflex, a late response and is often used to assess the S1 nerve root, or sometimes the sacral plexus, which can be involved in radicuolpathies and neuropathies. If you are not having symptoms it is likely mild but I would speak with your neurologist for a full examination and further guidance. ...Read more

Slow reflex in foot?

Slow reflex in foot?

Slow foot reflex: Suggests possible nerve compression in lumbar or sacral spine, which could result from bulging/ruptured disc, bone spur compressing spinal cord or nerve root, or spinal stenosis. Suggest seeing orthopedic or neurosurgeon for evaluation, tests (including mri), options for treatment. If u have foot drop or similar problems, do not delay. Sooner the treatment, less damage. ...Read more

When something or someone unexpectedly touches me eg. My leg, it will involuntarily reflex/pull away. Is this normal? Because I find it quite strange.

When something or someone unexpectedly touches me eg. My leg, it will involuntarily reflex/pull away. Is this normal? Because I find it quite strange.

Fight or Flight: It sounds like when you are caught off guard that you pull away, correct? An unexpected touch can trigger a "fight or flight" response/reflex where you attempt to get away from the "danger". As you quickly become consciously aware that there is no real danger - that response is limited to just pulling your leg away. ...Read more

Babinski reflex in adults one foot and the other foot didn't have any reaction would that be?

Babinski reflex in adults one foot and the other foot didn't have any reaction would that be?

Spine or brain: Babinski reflex suggests an upper motor neuron disorder. Since the spinal column and the brain are organized into "halves, " one-sided babinski suggests a lesion on one side of the spinal cord, brainstem, or brain. It could be as simple as an entrapped nerve or as serious as a stroke. Neurology consult is strongly recommended. ...Read more

What is the normal response of a foot plantar reflex?

What is the normal response of a foot plantar reflex?

Foot reflex: Not sure what you are talking about. If you mean when a doctor rubs a reflex hammer on the bottom of your foot. Then that test is called babinski sign and this tests for brain damage. The upper motor neurons are damaged by the big toe going up and the other toes flair out. Very distinct response. If you have this you may want to be referred to a neurologist. ...Read more

Isit normal when stand on wood plank and striking it with a hammer, that the impact causes a reflex in the foot caused by the vibration of the impact?

Isit normal when stand on wood plank and striking it with a hammer, that the impact causes a reflex in the foot caused by the vibration of the impact?

Yes, maybe and no.: Yes. The impact cause a vibrational energy wave that be picked up by special sensors on the bottom of the foot. The reaction can be either enhanced or reduced depending on physiological factors involving the nerves. ...Read more

Why don't I have a knee reflex in my right leg but I do in my left?

Why don't I have a knee reflex in my right leg but I do in my left?

IDK: Do you have any neuromuscular disorders? Do you walk normal? If so, the reflex should be there. Sometimes can be harder to illicit reflex on one side in doctors office by hitting ligament/tendon just right. If you haven't seen doctor, have him/her check it out. ...Read more

EMG/NCV report says "H-Reflex at left tibial nerve was 40.15. It was significantly prolonged compared to other leg." Can this cause swelling in leg?

EMG/NCV report says "H-Reflex at left tibial nerve was 40.15. It was significantly prolonged compared to other leg." Can this cause swelling in leg?

Nerve slow, swell no: Slowing nerve will not cause local, swelling. You should ask if the condition causing the nerve slowing might do this, and ask your doctor. There are multiple causes of swelling, most are benign, but some very serious, and you need correct evaluation to determine which is your cause. ...Read more

Can u have the babinski reflex in one foot? My right foot is positive, I am having many neuro. Issues on my left side. Wondering if that is related

Yes: Yes, that is definitely a sign of neurological problems. And it is contralateral (if a lesion is on left, symptoms are on right). ...Read more

Can u have the babinski reflex in one foot my right foot is positive, I am having many neuro. Issues on my left side. Wondering if that is related.

Yes: It's fairly common even for normal folks to sometimes have a babinski. It's easier to check on someone else than yourself. It's only one piece in the puzzle that every "neuro" patient is. Glad you're proactive. ...Read more

I'm a medical student. I've had foot pain for 8 years. In class I find out I don't respond to the plantar reflex. Related to my foot pain?

Depends: Depends in part on what the cause of your foot pain is. Most foot pain problems are not associated with reflex changes, but there are a couple examples. A chronic S1nerve root compression will cause a loss on the Achilles reflex and can be associated with pain in the sole of the foot. There are a few other possibilities as well, or they could be unrelated. A good exam will tell likely cause. ...Read more

Can missing several stairs going down the stairs and landing with all of your weight on one foot multiple times cause reflex sympathetic dystrophy?

Can missing several stairs going down the stairs and landing with all of your weight on one foot multiple times cause reflex sympathetic dystrophy?

Absolutely: Could have caused it the first time. Hard to know exactly why crps occurs after some injuries and not all of them or even most. Please get a full eval, by a PMR or orthopoedist to make certain your diagnosis is correct and not a missed fracture or nerve entrapment. And, we are assuming the pain is in the injures limb ...Read more

My doc thinks I have sympathetic reflex dystrophy. Would this explain the horizontal ridges on my big toe and foot becoming cold with elevation?

My doc thinks I have sympathetic reflex dystrophy. Would this explain the horizontal ridges on my big toe and foot becoming cold with elevation?

RSD/ ridges: RSD affects the nerve function. Esp autonomic nerves that control temperature regulation and sweating and swelling. The lines or ridges can be from the swelling increasing or decreasing. See a neurologist or a physical therapist. Aggressive physical therapy to stop the nerve irritation helps. There are also topical and oral meds that can help ...Read more

Do I probably have msa rather than Parkinson's because of poor balance and having a positive babinski's reflex sign in my left foot?

Do I probably have msa rather than Parkinson's because of poor balance and having a positive babinski's reflex sign in my left foot?

Challenging: You describe neuropathy, perhaps ataxia, and parkinson's. Would actually wonder if you possess olivo-ponto-cerebellar degeneration, or some parkinson's plus syndrome. Msa can be considered if you show autonomic dysfntn with urinary incontinence, postural hypotension, (helpful is association with sleep apnea, stridor and anterocollis). This is a job for an experienced movement disorder doc. ...Read more

My daughter 4 yrs old still had muscle weakness, atrophy, hyperreflex, positive babinski reflex affected only left leg.?

Neurologist: Not sure what workup has been done, and what diagnoses have been made, but I would highly suggest getting a neurologist involved to investigate. This constellation of symptoms suggests an issue at the spinal cord level, or a nerve degeneration issue, and requires immediate evaluation. ...Read more

My 7 week old's foot sometimes shakes when sleeping and when the foot is pushed back toward the shin. Is this a reflex? Is it normal?

My 7 week old's foot sometimes shakes when sleeping and when the foot is pushed back toward the shin. Is this a reflex? Is it normal?

Normal: These symptoms are normal for an infant. Due to their immature nervous system they will have some "shakes" and reflexes that would be pathological in an adult. If you touch the baby's foot when it is shaking at it stops the shaking this normal. If the shaking persists then have the infant's doctor exam him. ...Read more

Comments: I am guessing your concern focuses on prognosis, and hopefully, you are in a therapeutic program involving physical therapy and bracing. Even passive exercise will provide value. Your described reactions are to be expected at this point, and expect some further healing over the next 6-7 months. The ultimate degree of recovery cannot clearly be predicted, but keep working. All the best for you. ...Read more
