Chiropractic and Strokes

Chiropractic and Strokes

Having a stroke can be devastating! Not just for the person who has the stroke, but also for their family, friends, and caregivers. They are one of the leading causes of death and disability in the world.1

In fact, about 17 million people around the world suffer from a significant stroke every year! And about 5 million of them experience long term disability.2

Over the past 20 years, scientists have been showing that chiropractic care can actually change the way your brain works and how it controls your body, including movement and strength.

A stroke is something that causes a problem with the blood supply to the brain. This could be because of a blockage in an artery in the brain or a bleed in the brain itself. We all know how important our brain is, and without blood, it just doesn’t work, which is why strokes can be fatal or result in significant long-term disability.2

One of the most common disabilities after a stroke is muscle weakness, often on one side of the body. This may mean that after a stroke, a person has trouble using their arm or hand, or they may struggle to stand or walk.3 Living with muscle weakness can be really hard and have a big impact on a person’s ability to look after themselves or work.

There are lots of rehabilitative approaches that may help people who have had a stroke from physiotherapy through to robot-assisted therapies.4-6 But doctors and scientists are constantly looking for new approaches to help stroke survivors.3

Over the past 20 years, scientists have been showing that chiropractic care can actually change the way your brain works and how it controls your body, including movement and strength.7-16 A number of recent studies have shown that a single session of chiropractic care can result in an immediate increase in strength.17-20

In one of these studies, the researchers found a 16% increase in strength of leg muscles in a group of students after a session of chiropractic care.17 Another study reported an 8% increase in strength in elite athletes after they were adjusted by a chiropractor,19 and one more study found an 11% increase in jaw strength in a group of healthy people after chiropractic adjustments.18

Chiropractic May Help

But could chiropractic care help someone who has muscle weakness because they’ve had a stroke? A new study says maybe it can!20 In this study that was published in the reputable journal Scientific Reports, researchers looked at changes in strength in weak leg muscles after chiropractic care in people who had suffered from a stroke.20

The team of scientists that did this study measured the strength of weak leg muscles in chronic stroke patients before and after a single session of chiropractic care or a sham control session. They also used electrical stimulations of nerves in their legs, which could help them to work out whether any changes in strength came from their brain or something that was happening in their spinal cord. 

When they analyzed the data from their study, the scientists found an average improvement in strength of almost 65% in the affected leg of these stroke patients. They were blown away by this finding because 65% is a huge difference! They also found that these strength changes were due to changes in the way their brain was communicating with these weak muscles, as opposed to changes in their spinal cord.

These results are really exciting, but you do need to remember that the scientists only looked at immediate changes after chiropractic care, so they don’t yet know how long the changes last for. That’s why they’re now doing another study to look at how longer-term chiropractic care impacts how stroke survivors can walk and move.

However, these initial ground-breaking findings are really important and may mean that chiropractic care can help people who have had a stroke to improve their strength and ability to walk and move. So, if someone you know has suffered from a stroke, let them know that chiropractic care may really help to improve their brain/body communication and to get them moving again!

Pain Is Created In The Brain

By | Benefits of Chiropractic, chiropractic adjustment, Chiropractic Myths, gonstead chiropractic, gut problems, inflammation, kids chiropractic | No Comments

Did you know that scientists now know the feeling of pain is something your brain decides you should experience if it believes there is some tissue damage in your body? In fact, your brain can decide that you should feel pain even if it only thinks there is a potential threat of damage! 2-5

It may seem strange, but it’s totally up to your brain to decide whether you should feel pain or not. Your brain may decide you should experience pain even if you have no actual tissue damage yet,6 or your brain may not create the feeling of pain for you when tissue damage has actually occurred! 7 8 This is called the “pain paradox”. It means that the pain you feel does not always reflect the severity or even the location of your problem – if there is a problem at all. Science has shown beyond a doubt that pain is created in your brain! 2 4 9 10 

Sometimes pain can be very helpful and informative.1 Our brains create the experience of pain to let us know something is not ok.1 Maybe we are overexerting ourselves, or maybe we have had an injury that we need to be careful with to allow our body to heal. The pain can let us know what not to do while our body heals the problem.1 This pain is helpful and informative.1

If we listen to our body these pain experiences can be a good thing. But for some people, pain can persist even after the initial injury that caused it has healed.9 11 12 And for some people, the pain can spread to other areas that are not injured at all.6 For these people, the pain has become non-informative and non-helpful.9 11 12 The pain itself has become a problem. The brain has learnt to be in pain.9 11 12

The way the brain does this is very similar to the way the brain learns anything. It’s called neural plasticity – or brain adaptations.9 11 12 Brain scientists now know that what you focus on drives the way your brain will change.13-15 This can be a problem if you are focusing on your pain because it may make your pain worse. So, even if you’re in pain, try to focus on the good things in your life instead of your pain. Focus on what is working well. Focus on what makes you happy. This alone can help you!1

Brain scientists who have studied the effects of chiropractic spinal adjustments, have discovered that adjustments may change brain function.16

Chiropractic has a neuroplastic effect on the brain.16 In particular, adjustments change function in a part of your brain called the pre-frontal cortex.17 This part of your brain is actually the part of your brain that’s very involved in pain becoming chronic.8 18-21 This might be why getting chiropractic care early on when you have a problem has better long-term outcomes.22 It might also be that chiropractic care can prevent pain from becoming chronic.22

Neuroscientists believe that chiropractic care most likely helps reduce your feeling of pain by helping your brain ‘turn down’ or ‘switch off ’ the perception of pain in your brain.23 This means chiropractors may or may not adjust your spine exactly where you feel that it hurts. They are looking for parts of your spine and/or body where there is a lack of proper movement and they will adjust you there – so don’t worry if it’s not where you feel the pain.

Chiropractic Care and Breastfeeding

By | Benefits of Chiropractic | No Comments

For many mothers and babies, breastfeeding can be a real challenge! We know that about 80-90% of mothers try to breastfeed at birth, but by 1 week of age as few as half of the mothers are still exclusively breastfeeding. What does the research say about the potential for chiropractic care to help with breastfeeding problems?

It is recommended that babies should be exclusively breastfed until they are about six months of age, but only about 1% of mothers continue to exclusively breastfeed until this age.

There are of course lots of reasons that mothers give up on breastfeeding… from sore nipples to inadequate milk supply, or baby having issues with latching or sucking. All too often these problems lead to too much pain, or even a breast infection and ultimately, and understandably, the mother gives up on breastfeeding because it just gets too hard. This is a real shame because we know that breastfeeding is important for baby’s health.

We know that babies who are breastfed are less likely to suffer from ear infections and tummy bugs, they’re even less likely to develop asthma or other conditions that can be life-threatening. It just goes without saying that nature knows best, and that breastfeeding is the optimal form of nutrition for infants. So, if someone is having issues with breastfeeding what can they do about it? Luckily help is available! One healthcare professional that many new mothers turn to for help is their family chiropractor. But why might a chiropractor help with breastfeeding? Well, the answer is simple. Chiropractors see babies to help improve the way their body and nervous system functions, so they get the best possible start in life.

But why might a baby have problems with the way they move and function? That’s another simple question to answer. Spending nine months growing in mom’s tummy can get really cramped. Before a baby is even born, the pressure they’re under in mom’s uterus can cause changes to the way their bones move and fuse together or the shape of their skull. And then the strains that the baby faces during delivery, either as they pass through the birth canal, or from forceps or other forms of assisted delivery, can cause injuries to the baby’s spine or nervous system or other joints that doctors and parents may not even be aware of.

We know that successful breastfeeding relies on lots of complex movements that involve the spine and jaw. And we know that babies with breastfeeding problems often have imbalances in the way their spine and jaw work. We also know that chiropractic care has a positive impact on the way our spine and jaw work. So, it makes sense that chiropractic care might be able to help with breastfeeding problems.

So, what does the research tell us about whether chiropractic care may help mothers and babies who are struggling with breastfeeding? At this stage, large, costly clinical trials haven’t been done to really study how much chiropractic care can help, so we can’t say for sure how effective it is. But what the research that has been done tells us is that many mothers who take their babies to chiropractors because they’re struggling with breastfeeding, report really good changes after their baby is adjusted.

In one study that was conducted in the UK, the researchers followed 114 mothers and babies who were presented to a chiropractic teaching clinic for care. All the babies were under the age of 12 weeks, and they were all unable to breastfeed exclusively.

The babies were seen by the chiropractic students up to 9 times, and the students used low force chiropractic techniques to release tension and improve muscular imbalances. The researchers were most interested in whether a baby would be able to breastfeed exclusively after they received chiropractic care, but they also looked at the mother’s rating of overall improvement and baby’s weight gain.

What they found was that all the children showed some improvement, with over three-quarters of them being able to exclusively breastfeed after just 2 to 5 chiropractic visits over a 2-week period.

From a study like this, we don’t know how much the placebo effect was involved, and with care provided by chiropractic students, we don’t know if the results would have been even better if an experienced chiropractor provided the chiropractic care. But what we do know, is this study suggests that for some babies with breastfeeding problems, chiropractic care may help mother and baby to breastfeed exclusively, which is a great thing for mother and baby alike.

We also know from other research, that when appropriately applied, chiropractic is known to be safe for kids and babies. So, if you’re having trouble with breastfeeding, it’s a good idea to have your baby checked by a chiropractor to make sure they get the best possible start in life.

How Often Should You Visit Your Chiropractor?

By | Benefits of Chiropractic, chiropractic adjustment, Chiropractic Myths, Ear Infections, gonstead chiropractic, gut problems | No Comments

When you first see your chiropractor, you may be among the many people who ask, ‘how often do I need to come?’ Often the answer people want to hear is ‘once’ but chiropractic care, like most things that are really good for us, rarely makes a long term difference to your health and wellness after just one visit.

One reason a single visit to your chiropractor may not make a long-term change is that it usually takes years for the problem to develop that motivates someone to first see a chiropractor and it can take many visits to the chiropractor to correct that problem.

Seeing your chiropractor can be a little like going to the gym. It takes time, frequency and follow up.

One way of looking at it is that it can be like the thousandth straw that breaks the camel’s back. A problem can build up day after day as you sit hunched over your desk, or bend and twist as you lift, or tense up as you deal with your daily stress and then one day, you bend to tie your shoelaces and all of a sudden something hurts! You can rest assured that tying your shoelaces isn’t what caused the problem, it’s simply the thousandth straw that broke the camel’s back (or was too much for your back) and that’s why you’re in pain.

There will usually be changes to the way the supporting muscles in your spine work that build up over time until your muscles can’t cope anymore, and symptoms appear.1-2 So, seeing your chiropractor can be a little like going to the gym. It takes time, frequency, and follow up. Working with you to correct the problem and help your brain and the muscles in your spine communicate or ‘talk’ with each other again so you can regain the stability you need to function properly and resolve your aches and pains.3

But how long will this take and how often do you need to be checked by your chiropractor? Everybody is different, so your chiropractor will be guided by their clinical experience, and what your goals are when they recommend a care plan for you. 

US Research Study

A new research study was recently published that suggests, in the early stages of chiropractic care, the more often you get adjusted, the better the results you enjoy, and this can also be better for you in the long term as well.4

In this study, that was conducted by scientists in America, they looked at 256 people who had chronic, regular headaches and divided them into groups who either received chiropractic care once a week, or twice a week, or three times a week, for up to six weeks, or they received no chiropractic care at all and instead were given light massages over the same 6-week period. Previous studies have shown that people with this kind of headache often respond well to chiropractic care.

The scientists in this study were most interested in how many visits per week to the chiropractor showed the best results. They looked at how many days a week a patient suffered from headaches at the end of the study and whether any changes in headache frequency between the groups were still there up to one year later. What they found was that the patients who were seen by their chiropractor most regularly, so up to three times a week, had fewer headaches than those who were seen once or twice a week, and they were much better than the patients who received no chiropractic care at all.

In fact, after one year, the patients that had been seen three times a week had over three fewer headaches per month compared to the patients who only received a light massage. So, these effects obviously lasted.

The more you get adjusted, the better the results that you will enjoy.

This study was done in people with chronic headaches, so we can’t be sure if the same differences occur in people with other problems who see a chiropractor. A similar study in patients with chronic low back pain did find that people who were adjusted more often had the best results, but the results weren’t as clear as the study done on patients with headaches.

The studies suggest that seeing a chiropractor more often when you begin care has real, beneficial, long-term effects to the way your spine and nervous system works, but how much you benefit may depend on what’s wrong with your spine when you begin care.

So, when you go and see your chiropractor, know that their recommendations for your plan of care are based on what their clinical experience tells them is best for you, and that the research suggests more frequent adjustments has the biggest positive impact on your health and wellness.

Handbrake In Your Brain

By | ADHD, Allergies, Benefits of Chiropractic, chiropractic adjustment, energy, High Blood Pressure | No Comments

Handbrake in Your Brain

Does it feel like you have a handbrake on your muscles and you don’t have your usual strength?

This idea of having a handbrake on your muscles may actually be more real than you think – maybe not a handbrake on your muscles, but a handbrake in your brain which is what controls your muscles and tells them to contract.

Chiropractic care can make you stronger over the last few years studies have shown that when you get adjusted by a chiropractor it can make you stronger. One study reported in a group of students who received chiropractic care, that they were actually able to produce 16% more force in their leg muscles after a chiropractor had gently checked and adjusted any dysfunctional spinal segments, or what chiropractors call vertebral subluxations.1

What does the research show?

Researchers in New Zealand followed up this study in Tae Kwon Do athletes, and again showed that even in a group of elite, highly trained athletes, a single session of chiropractic care can improve their strength.2 But what does this have to do with handbrakes in the brain you may wonder? Well, in a new study by the same team of researchers, they wanted to see if chiropractic care resulted in an increase in the way the brain could drive the muscle in the subject’s arms.4 To do this, they measured the participant’s bicep’s muscle strength, and then measured something that’s called ‘central inhibition’, before and after a single session of chiropractic care, or just moving their heads around as a control intervention. This ‘central inhibition’ measure is a bit like the brain’s handbrake to the muscle. There are two ways the brain can increase the way your muscle contracts. It can either press the gas pedal or it can release the ‘hand brake’ to that muscle. The scientists wanted to know if a particular type of handbrake changed after these subjects got adjusted. The technical term for the method they used to record this was ‘TMS twitch interpolation technique’ and it allows them to explore the way the participants brains are driving their arm muscles… in other words it measured the degree to which their brain was pulling the handbrake to that particular muscle. What they found was that there was a difference in the degree of central inhibition to the bicep’s muscle only after they were adjusted, compared to when they did the control movement of the neck. There was less inhibition, suggesting the brain had released the handbrake to the muscle after they got adjusted. So, this may be one of the reasons why the previous studies showed that chiropractic care could increase strength, because maybe chiropractic care is reducing the central inhibition to your muscles, or in other words, releasing the handbrake to your muscles making it easier for your brain to move your muscles and produce more strength. So, if you feel like you’ve got a handbrake in your muscles or in your brain, maybe you should go see a chiropractor and see if they can help your brain release the handbrake so that your brain can more efficiently control your muscles and perhaps even help you to get that jam jar open.

Do you suffer from headaches or know someone who does? If you do, you are not alone.

The head is the most common site of pain in the body. Headaches can range from milk pain through to intense pain that leaves you bedridden.

Headaches are a sign that something is wrong. Your brain will create the sensation of pain if it thinks there is something wrong or if it thinks there is a potential problem – e.g. Your brain will give you a headache if you have taken too much medication – letting you know there is some chemical toxicity going on! And some headaches are a warning of life-threatening illness.

Chiropractic Care May Help

We know now, from research studies, that when your spine is not moving properly, this changes the way your brain perceives what is going on in and around your body, the way it integrates other sensory information, and the way it controls your body.1-3 The movement of your spine is very important for your brain to know where you are in space, and since you cannot see your spine with your eyes, your brain relies on the information it receives from the small muscles closest to your spine and skull. If the segments of your spine are not moving properly this may, for some people, manifest as headaches. Others may experience back pain. It’s possible that problems in the spine may even lead to some babies experiencing colic or some kids may not be fully aware of their bladder at night and end up with bedwetting. Research has shown that when a chiropractor then gently adjusts these subluxations, it helps the brain to more accurately ‘see’ what is going on in and around the body.

So, when you get adjusted by your chiropractor, if your spinal dysfunction was manifesting as headaches, these may improve. If your spinal dysfunction was manifesting as back pain, then this may get better.

Researchers have reviewed all of the randomized controlled trials that have looked at the effects of chiropractic care or spinal manipulative therapy on headaches.4-6 The results show that chiropractic care does really help some people with headaches and migraines! We don’t know for sure who will respond well, but for some people, when they get under chiropractic care, their migraines may almost completely resolve within just a couple of months. In another study,8 80 patients with chronic headaches that were due to a problem in their neck, called cervicogenic headaches, received eight weeks of chiropractic care and another similar group of 80 patients received eight weeks of light massage. What they found in this study was that the patients receiving chiropractic care improved significantly compared to the control group that received massage. These studies suggest that chiropractic care may really help some people suffering from different types of headaches. So, if you experience headaches, why don’t you consider chiropractic care and make sure your spine is functioning well so you can operate at your best!

Young As Your Spinal Column

By | Benefits of Chiropractic, chiropractic adjustment, Chiropractic Myths | No Comments

Do you realize the importance of the spinal column? These bones that run up and down your spine protect the most important system in the human body, the central nerve system. The spinal column allows protection while enabling proper flow of information from brain to body and visa versa. Sound important enough yet?

When a subluxation occurs, (misalignment within the spinal column placing undo stress upon the central nerve system) the brain perceives “road construction” as well as what the body needs to do to function correctly. The saying “in alignment” holds some merit when it comes to your health and well-being. Your body craves alignment, when you are properly aligned, your bones, not your muscles,  support your weight, reducing effort and strain on the spinal column.

The spinal column is specifically  designed to allow nerves to flow through and regulate your heart, lungs, thyroid, biceps, lymph. Remember every system falls under control of the central nerve system. Its communication pathway is via spinal nerves that exit out of spinal bones. Stop and think. Clap your hands together, hold your breath for 30 seconds, these maneuvers you perform originate in the brain and then are coordinated via your spinal nerves to the tissue cell of importance.

The good news: with regular spinal check-ups you can ensure optimal function out of your central nerve system. Your body’s ability to heal is greater than anyone has permitted you to believe. Your health and vitality are related to your spinal health and alignment. By receiving correct spinal adjustments the body is able to restore itself to a higher level of health. Have you ever heard of a spinal transplant? Neither have we, so take care of the one you have. 

Strengthen The Inside

By | Benefits of Chiropractic, chiropractic adjustment, Chiropractic Myths | No Comments

“It’s what’s on the inside that really counts.” This saying is used for many things, the main one being relationships. Just because someone looks “good” on the outside doesn’t necessarily equate to anything on the inside. Looks can be deceiving! When it comes to your health and well-being, look to the inside of the body first and foremost.

“While other professions are concerned with changing the environment to suit the weakened body, Chiropractic is concerned with strengthening the body to suit the environment”- B.J. Palmer, D.C. This text really sums up what and how Chiropractic suits your lifestyle. Chiropractors are trained to access your central nerve system (CNS) for subluxations (misalignments within the spinal column placing undo stress upon your CNS). By locating and adjusting subluxations, your body is better able to perceive its surrounding environment, thus keeping you in an ideal state of health.

You see, “bad” health has to start from within the body. You should take care of your body, it’s the only place you have to keep living! Forgo the “theory” that you have to take external “things” (drugs, medicine, lotions, oils, potions) to sustain your health. Start first and foremost by addressing your CNS and the health of the spinal column.

Your ability to perceive and sustain health is directly reflected towards the health of your CNS and spinal column. Think of efficiency. You would never buy a furnace that is only 60% efficient. So, why would you settle for a body that is? Efficacy of health is proportional to the health within the inside. Taking responsibility of health begins with proper spinal alignment, thus allowing your CNS to better able control all systems within the body.

An interesting thought is just because you’re not sick does not mean you’re healthy. Chiropractic does not keep you from getting sick, it enables your body to adequately adapt to the stressors you place upon it. The chiropractic adjustment removes spinal stress to allow optimal function. The adjustment cannot be replaced by physio, lasers, massage or medication.

The Power Of ‘Advice’

By | Benefits of Chiropractic, chiropractic adjustment, Chiropractic Myths, inflammation, kids chiropractic | No Comments

Age old advice can be misunderstood and often times falls upon deaf ears. Too often we must deal with our own obstacles to actually learn from a life event. Advice, while it is easy to give, often requires the one giving it not to have to lift a finger to accomplish it. When it comes to your health and well-being we have a reliable truth that your body is designed to be healthy. The steps you take to accomplish this daily task of regular health often times comes from ‘advice’.

So take a grain of salt and listen to some words of encouragement, backed up with laws of truth. No advice given here!

Your body is innately designed to keep you healthy on a daily basis. Ultimately running the ‘ship’ is the central nerve system (CNS). For without your CNS daily functions would not occur, thus rendering you useless. Regular check-ups to ensure optimal function of your CNS comes throughout visiting a Chiropractor to check your spinal column for subluxations (misalignment within your spine placing undo stress upon your body).

There is no such thing as “One and done”. If you have been given the advice that a Chiropractor check-up is an emergency situation and after an adjustment the body is automatically restored back to its orginal state then this is bad advice.

Whether the subluxation is an acute or chronic problem it will still require time to properly heal correctly. Just because you cannot see a wound healing within the spinal column does not mean it doesn’t exist. Take your skin for example. If you have ever sustained a deep cut, it can take weeks to months for the skin to heal. Most important here is that the part of your skin that you can see will not be the same as the surrounding skin tissue. Something changed and it did not take overnight!

Take the time to understand that age old adages are what they are! If you skip the healing steps you will miss the healing stages that your body is supposed to go through!

The Importance Of Muscle Memory

By | Benefits of Chiropractic, chiropractic adjustment, Chiropractic Myths, inflammation, kids chiropractic | No Comments

Why do Chiropractors specialize in the Central Nerve System (CNS)? EASY! The CNS is the master controller within your entire body. Every tissue cell that you had, have, and will make is processed and controlled via your CNS. It’s no wonder that there is a specific field (Chiropractic) dedicated to managing the overall function of how your CNS operates on a day to day basis.

Did you know that your brain weighs only 3 lbs and has to coordinate all internal and external functions every second that you are alive!? Specifically, it coordinates external responses via your sensory organs, eyes, ears, nose, etc.

Did you know that your muscles are also organs? Not just your muscles that you workout at the gym, but also the tiny intrical muscles that surround your spine. When a subluxation (misalignment within the spinal column) occurs, the information that the muscles are supposed to send to the brain become dysfunctional. Your brain can still function when a subluxation is present due to muscle memory based on past experiences that you have encountered before.

When a subluxation exists for an extended period of time, your brain is not fully aware of its surroundings. Overtime, this leads to a slow breakdown in the communication between brain and body.

In order to correct the communication breakdown, this is where your Chiropractor comes into play. Positive muscle memory is established when your Chiropractor properly locates the subluxation, and adjusts the dysfunctional segment so that your brain can “wake up” and correct the spinal segment. Doing so will restore the spinal column to its proper positioning, and allow the body to properly adapt overtime.

Time is key. Just like correcting a bad habit, you need to stay on top of it, and require patience while you are breaking the cycle that your body has created. If you accelerate the process and do not give the body ample time to heal, you rush the experience and never fully heal. It takes time to make a problem, and it requires time to make the change. Choose wisely!
