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

What are some physiological (non-psychological) causes of exaggerated spinal reflexes (i.E. Exaggerated jerking/flinching in response to light touch)?

What are some physiological (non-psychological) causes of exaggerated spinal reflexes (i.E. Exaggerated jerking/flinching in response to light touch)?

Startle vs DTR's: Your description of exaggerated jerking with light touch sounds like someone with very brisk "startle" reflex, as in post traumatic stress disorder. This is a physiological response to hypervigilance, as ptsd encompasses the whole person and his/her body. Hyperactive deep tendon reflexes (dtr's) can result from conditions like cerebral palsy, strokes, inflammatory diseases, and brain injury. ...Read more

Why hyperactive deep tendon reflex occure in hypocalcemia?

Spastic muscles : Muscles get "tetanic" when there isn't enough calcium. They contract more easily because the decreased calcium affects contractility of muscle fibers. ...Read more

Is repeated startle response (i.e "jumping") harmful after I've had a concussion? My job involves sudden, loud sounds that often provoke startling.

Is repeated startle response (i.e "jumping") harmful after I've had a concussion? My job involves sudden, loud sounds that often provoke startling.

May provoke symptoms: Although probably not harmful, loud noises and repetitive brain stimuli such as bright lights, heavy technology use, prolonged reading can all make concussion symptoms worse and prolong recovery. If you have to work, consider ear plugs or headphones if possible to reduce the loud noises and startling.

How does a hyperactive stretch reflex (due to spinal cord injury) result in clonus?

Brakes are released: The quick answer: the brain/spinal cord send electrical fibers to control the muscles. When the fibers are severed, the muscles "do their own thing", unregulated. http://www.livestrong.com/article/197920-causes-of-clonus/. ...Read more

Iq drop from martial arts/fighting, possible?

Yes. Which Style?: Yes. Obviously, any martial art or fighting that involves contact with the head can lead to concussion, traumatic brain injury, etc. There may be some styles which may be safer, such as Tai Chi & Aikido. These arts rarely have percussive impact. It all depends upon how you train. ...Read more

Is it rare to have reflex sympathetic dystrophy in the knee?

Is it rare to have reflex sympathetic dystrophy in the knee?

Yes: Rsd or chronic regional pain syndrome is usually seen in the upper or lower extremities and usually involves a wider area than the knee itself. For instance, we may see it involving the calf, ankle and foot or hand wrist and forearm. I have heard of this diagnosis being made in a single joint like the knee but I have never seen it myself. ...Read more

Left leg flex-or tendon unresponsive, when seated or standing or walking unable to point toes/foot upwards using muscles/tendons partial loss of sensation in left leg from knee down, causing embarrassing limp, 25 year old male

Left leg flex-or tendon unresponsive, when seated or standing or walking unable to point toes/foot upwards using muscles/tendons partial loss of sensation in left leg from knee down, causing embarrassing limp, 25 year old male

This : This sounds like a serious issue that should be evaluated in-person by a qualified physician! if your weakness was sudden, there are numerous possible causes, most importantly associated with your nervous system. It does not sound like you had a trauma, so muscle-or-tendon ruptures are unlikely. The most common reason for this problem is an acute disc herniation in the lumbar spine, that can occur without back pain or even any kind of bending/lifting injury. This causes nerve compression that gives patients typically radiating leg pain, numbness and weakness. The muscles that are associated with each lumbar spine level need to be tested individually during a good physical examination, and the distribution of your numbness should be traced. That can often lead to a pretty good diagnosis, even before imaging studies are done. You will probably need a set of standing lumbar x-rays and then possibly an MRI of your back to determine the real cause of the problem. There could be an inflammatory problem with onevof your nerves in the buttock or leg, although that is not as common as nerve root compression in the lower spine. Very rarely can individual nerve roots be affected with a disease inside of the cauda equina, the lower part of your nervous system inside of the lumbar spine, so that is unlikely. Even more rare would be a spinal cord problem higher up in the spine, or some kind of stroke inside of your brain, so that would not be the first thing your doctor will be looking for. Make sure you tell your physician as clear as you can when the problem started, where you feel weak, and where the numbness is (front, side, back of the lower leg?). Associated fever, chills, recent weight loss and problems with urination are important to convey to your doctor also. Do not wait too long to go see someone. Hopefully you can be treated with a course of anti-inflammatory medicines (similar to ibuprofen) and maybe physical therapy to see if things improve. Even with weakness, there is no good evidence for early surgery, as most patients -even if they were weak for a long time from nerve-root compression- eventually regain their strength just fine. Depending on the evaluation and possible MRI scan, do not let yourself get scared into surgery right away; try non-operative treatments first. If things do not improve, and there is indeed a significant amount of nerve compression in the lumbar spine, surgery might be the answer, and it is often very successful for this. Good luck! ...Read more

Could exuberant knee reflex be a symptom of spinal cord injury?

Could exuberant knee reflex be a symptom of spinal cord injury?

Yes: Nerves originating from the brain suppress reflexes to a degree. With certain spinal cord injuries, this suppressive effect is interrupted, and reflexes can be very brisk as a result. ...Read more
