‘Dem Bones’
The hip bone’s connected to the back bone,
The back bone’s connected to the neck bone,
The neck bone’s connected to the head bone,
Now shake dem skeleton bones!
I heard this song on the radio a lot when I was just a young boy in the UK. Even if I didn’t get all the words correct, the song – actually a spiritual whose lyrics were taken from a chapter in the Bible (Ezekiel 37) – perfectly describes the function of joints. Whatever and wherever their type or location, joints all do the same thing – they connect and help to move ‘Dem Bones’
Joints are always ‘switched on’, always active and always an essential part of daily living. Perhaps in part because of this nonstop motion, joint (or ‘musculo-skeletal’) pain accounts for up to a third of all physician visits. We don’t leave home without them, and if our joints are not in good shape – we sometimes don’t leave home at all! Generally joint pain is the result of osteoarthritis, can affect anyone and typically starts as our bodies begin to show the effects of aging. Incidentally this effect is all the more noticeable with ‘Usual’ aging (which has and will continue to be discussed in this blog many times!)
The good news is that joint pain is not inevitable with aging and there are a number of things you can do to encourage and maintain joint health
But first – a quick ‘Cliffs Notes’ overview of joints and their major components, because being jointly responsible also involves learning more about something that can impact your health, wellness and physical function.
Joint Moves
Every joint has the same make up – only the way they operate may differ. For example shoulders and hips work more like a ball-and-socket, while knees work more like a hinge. All joints have the same basic function: They connect one bone to another and give us the ability to bend, twist, and wave our hands (or anything else) in the air
In Brief, the main components of joints are
- Connective Tissue – AKA ‘Ligaments and Muscles’. The ligaments provide an extremely strong connection between one bone and the next. The muscles also connect bones but also provide the means for movement. Essentially the ligaments provide joint stability and the muscles provide joint movement.
- Cartilage – AKA ‘The Smooth Cushioner’. Cartilage is a tough, fibrous disc-shaped piece of tissue that acts as a cushion between joints. Because it is also somewhat elastic it acts as a shock absorber to prevent bones from grinding against each other.
Osteoarthritis appears when we start to lose that cushioning, and a number of things can contribute to the loss, often all at the same time.
Here’s a list of the ‘usual suspects’
Aging: Cartilage thins as we age and over time the surface of cartilage can change from smooth to irregular and rough. That’s when you start to notice …. those things that you used to take for granted like getting out of the chair or getting up the stairs etc. It used to be done without much thought … but now …. ?
Previous injuries: Even if you didn’t think much of them at the time, seemingly minor joint injuries when you were younger can sometimes prompt joint pain in later life. They can cause microscopic injuries to muscles and ligaments (known as ‘microtraumas’) which can produce joint pain ‘down the line’.
Inflammation: Small injuries (microtraumas) can upset the biomechanics of your joints. That, in turn, changes the internal make up of the cartilage. These microtraumas can cause low levels of inflammation which then releases chemicals that are damaging to joints over time.
Muscle loss: Muscles help to support joints. The more muscle you have – the more potential muscle strength you have – and the more you will be able to absorb the impacts and ‘poundings’ of daily living. This produces less stress on the joints. Less joint stress = more joint health!
Excess weight: More weight = more work for the joint = more damage (and more microtraumas) in the long run. This is especially true for knees, which have to support your body weight.
Ok so now you know the issues – here are some options for doing something about (most of) them. You will undoubtedly notice some similarities with previous posts on Successful Aging. This is NOT a coincidence!
Healthy Joints for Healthy Living
Stay at a healthy weight. This is probably your best option for joint health. Staying at a healthy weight will help reduce the microtraumas that damage cartilage. Research reports that a weight loss of as little as 11 pounds can reduce arthritis pain by 50 percent for many women. Weight loss (if you are already overweight) may also help slow the progression of osteoarthritis over time.
Stay active. Physical activity helps reduce stiffness in the joints. Low- or no-impact aerobic exercises like swimming, walking, or cycling twice a week or so is ideal. Strength exercises too are particularly effective for reducing symptoms of osteoarthritis (see below). When mixed with stretching and relaxation exercises, these make a highly pro-active approach for keeping joints working at optimal efficiency.
Stay strong. Weight training strengthens the muscles and ligaments that surround joints. Strong supporting muscles protect joints from damage. I will be blogging about the best, safest and most efficient ways of increasing strength in upcoming posts
Stay cool. Some people experience pain, swelling or discomfort after exercise. If this applies to you, icing your joints for 10 minutes or so after the activity can help. When you exercise, a lubricant called synovial fluid is drawn into your joints. However, if the fluid sticks around too long after exercise, it can cause cracks in the cartilage. Ice helps to move the fluid out of the joint and into the lymphatic system, the garbage disposal of the body.
Stay with a good diet. Studies show the omega-3 fatty acids found in fish can help to reduce symptoms of joint pain and also change the levels of inflammation that may be causing some of the pain. Fish oil appears to slow the production of inflammation-signaling cells. The best sources are fish such as salmon and tuna. Research shows that 400 to 800 International Units (IUs) of daily vitamin D may also help protect your joints, via an anti-inflammatory effect. As a comparison, one cup of milk contains 100 IUs, and three ounces of salmon has 300-650 IUs.
Look out for more posts on diet and nutrition in the future.
