Damaged Sciatic Nerve Repair

Best Stretches for Sciatica

Hello I'm Heather Moore owner ofTotal Performance Physical Therapy. Today we're going to go over the best exercisesfor sciatica. There's really one main stretch that you can do a bunch of different waysif you're getting numbness and tingling down your leg, if you'r e getting pain throughyour back, in your butt you should do this stretch multiple times throughout the day,when you do it you want to try and hold it for about 30 seconds, you want to try andperform 6 repetitions if you can't do it for that long that's okay hold it for as longas you can, if for any reason these are going to increase your pain you need to stop immediatelyand call your but this should alleviate

a lot of your body pain specially if you aresitting for a long period of time or you get a lot of pain down your leg. The first oneis in the seated position you want to sit up nice and straight, you want to cross yourankle over your knee if you feel a stretch there that's where you need to stop, if youdon't feel a stretch there all you wann do is sit up and lean forward and you shouldfeel a greater stretch through your butt, through your hamstring which is in the backof your leg and through the side of your leg, you may even feel a little bit on your backdepending on where your tight is again this shouldn't hurt and should feel like a goodstretch, you could do this sitting at your

desk all day long, you also want to make surethat you concentrate on both sides not just the side that hurts, piriformis muscle whichis what this is stretching on both sides and will tag evenly on your sacrum or your tailbone so you want to make sure that you do both sides and not just one. The next wayto do this stretch is standing up, you want to find a surface where you can put your leg,your hip at about 90 degrees and you're going to bring your foot up and you're just goingto have it lay on the table and you're going to let your knee drop to the side, if yourknee doesn't fall all the way down that's okay, don't force it down let it just staythere again if you get, if you're in this

position and you don;t feel a stretch youcan now begin to lean forward, you're going to feel the stretch in your back, in yourglut, in your hamstring and all the side of your leg, this should not be painful it shouldfeel like a nice stretch this one also you want to do 30 seconds hold about 6 repetitionsand you want to make sure that you hit both sides. The final way to do this stretch islaying down, so you want to lay on your back and this is a good thing to do when you getup in the morning, go ahead and bend both your knees up and then you're going to crossyour ankle over your knee, now again if this is where you feel a stretch stop right thereand hold it, if you don't feel a stretch in

this position you're going to reach both armsbehind this leg and you're going to pull it up towards your chest, you should feel a stretchagain in the back, in the glut, in the hamstring or maybe even on the side of the leg, it shouldnot hurt it should feel like a nice gentle stretch, you want to hold this about 30 secondsand you want to do about 6 of those you can do this as many times during the day as youwould like there is no set number or times that you can do this, anytime your tight youcan do this and it will not harm you.

3DPrinted Guide helps regrow complex Nerves after injury

A team of researchers from various universitiesin U.S has developed a firstofitskind, 3Dprinted guide that helps regrow both thesensory and motor functions of complex nerves after injury. The groundbreaking researchhas the potential to help more than 200,000 people annually who experience nerve injuriesor disease. Nerve regeneration is a complex process. Becauseof this complexity, regrowth of nerves after injury or disease is very rare Nerve damage is often permanent. Advanced3D printing methods may now be the solution. The researchers used a combination of 3D imagingand 3D printing techniques to create a custom

silicone guide implanted with biochemicalcues to help nerve regeneration. The guide's effectiveness was tested in the lab usingrats. To achieve their results, researchers useda 3D scanner to reverse engineer the structure of a rat's sciatic nerve. They then useda specialized, custombuilt 3D printer to print a guide for regeneration. Incorporatedinto the guide were 3Dprinted chemical cues to promote both motor and sensory nerve regeneration.The guide was then implanted into the rat by surgically grafting it to the cut endsof the nerve. Within about 10 to 12 weeks, the rat's ability to walk again was improved.Scanning and printing takes about an hour,

but the body needs several weeks to regrowthe nerves previous studies have shown regrowth of linearnerves, but this is the first time a study has shown the creation of a custom guide forregrowth of a complex nerve like the Yshaped sciatic nerve that has both sensory and motorbranches. The exciting next step would be to implantthese guides in humans rather than rats In cases where a nerve is unavailable forscanning, the researcher said there could someday be a “library� of scanned nervesfrom other people that s could use to create closely matched 3Dprinted guidesfor patients.

Helping the body regrow nerves Science Nation

♫MUSIC♫ MILES O'BRIEN: Combat, cancer and accidents all can cause devastating nerve injuries. Sometimes, the body heals on its own. CHRISTINE SCHMIDT: Your peripheral nerves are the ones in the arms and the face, have an inherent ability to regenerate but only under ideal circumstances. MILES O'BRIEN: With support from the National Science

Foundation, University of Florida Biomedical Engineer Christine Schmidt is working to restore nerve function when injuries are more complicated. SURGEON: Took that muscle and rotated it, took it over the back of his elbow to cover – MILES O'BRIEN: Surgeons can sometimes move a nerve from one part of a patient's body to another. Schmidt has developed a method that grafts cadaver tissue onto the damaged area to

act as a scaffold for nerves to regrow themselves. CHRISTINE SCHMIDT: Basically what we're doing is removing all the cellular material that would cause rejection but leave behind the native architectures. You're putting this graft into the site of injury. And now, that graft is providing a scaffold for your blood vessels to grow in. And then once you have that recellerization your nerve fibers can then regrow, so then, ultimately regain that muscle function.

MILES O'BRIEN: Navy Veteran Edward Bonfiglio, wounded in Afghanistan, faced the prospect of an amputation. A graft was a welcome option. The company, AxoGen, distributes the grafts, which were developed based on work done in Schmidt's lab. JILL SCHIAPARELLI: And his family pressed the s to say, quot;Are there any alternativeséquot; He was a young, healthy, vibrant guy. And they had a great surgeon at Walter Reed who was willing to work with them to find those options.

CHRISTINE SCHMIDT: This is some of the micronized nerve that you're working with. MILES O'BRIEN: Schmidt and her team are also looking at other approaches to directly stimulate nerve growth using natural sugar molecules found in the body as building blocks, eliminating the need to transplant tissue. CHRISTINE SCHMIDT: So you don't have to actually take it from somebody's body. You can grow it.

MILES O'BRIEN: While the ultimate goal in nerve regeneration is reversing paralysis, Schmidt says intermediate successes, like improving lung or bladder function, can be invaluable to patients and their families. CHRISTINE SCHMIDT: So rather than saying we're going to try to tackle this humongously complex beast and try to get the patient to necessarily be exactly like they were before, why not provide some function that will have merit
