Which Weight Bearing Activities Build Bone in Adults?

When It Comes to Bone Building Activities for Osteoporosis, there’s Weight Bearing and then there’s Weight Bearing!

Ask just about anyone on the street what one should do for osteoporosis and the typical answer is- weight bearing exercises. And they would be partially right. Weight bearing, or loading activities have been shown to increase bone density.1 But that’s not the whole story.

Regarding weight bearing exercises, the million-dollar question is, “How much weight bearing is enough to stimulate bone growth and how much is too much to compromise bone at risk for a fracture? We know that there are incidents of individuals fracturing from just their own body weight upon standing. Recently patients have been asking about heel drops and stomping, and whether they should do them. One size does not fit all.

An alternative is to focus on “odd impact” loading. A study by Nikander et al 2 targeted female athletes in a variety of sports classified by the type of loading they apparently produce at the hip region; that is, high-impact loading (volleyball, hurdling), odd-impact loading (squash-playing, soccer, speed-skating, step aerobics), high magnitude loading (weightlifting), low-impact loading (orienteering, cross-country skiing), and non-impact loading (swimming, cycling). The results showed high-impact and odd-impact loading sports were associated with the highest bone mineral density.

Morques et al, in Exercise Effects on Bone Mineral Density in Older Adults: A meta-analysis of randomized controlled trials, found that odd impact has potential for preserving bone mass density as does high impact in older women. Activities such as side stepping, figure eights, backward walking, and walking in square patterns help “surprise the bones” due to different angles of muscular pull on the hip. The benefit, according to Nikander, is that we can get the same osteogenic benefits with less force; moderate versus high impact. This type of bone training would offer a feasible basis for targeted exercise-based prevention of hip fragility. I tell my osteoporosis patients that if they walk or run the same route, the same distance, and the same speed that they are not maximizing the osteogenic benefits of weight bearing. Providing variety to the bones creates increased bone mass in the femoral neck and lumbar spine.4

Dancing is another great activity which combines forward, side, backward, and diagonal motions to movement. In addition, it adds music to make the “weight bearing exercises” more fun. Due to balance and fall risk many senior exercise classes offer Chair exercise to music. Unfortunately sitting is the most compressive position for the spine and is particularly problematic with osteoporosis patients. Also the hips do not get any weight bearing benefit. Whenever safely possible, have patients stand; you can position two kitchen chairs on either side, much like parallel bars, to hold on to while they “dance.”

Providing creativity in weight bearing activities using odd impact allows not only for fun and stimulation; it also offers more “bang for the buck!”

With Osteoporosis, any exercise is good. Yes? No!

In 1984, Mersheed Sinaki MD and Beth Mikkelsen, MD published a landmark article based on their research with osteoporotic women. (Yes, it was 1984 but this is one study no one would want to reproduce).1

The study follows 59 women with a diagnosis of postmenopausal spinal osteoporosis and back pain who were divided into 4 groups that included spinal Extension (E), Flexion (F), Combined (E+F), or No Therapeutic Exercises (N). Ages ranged from 49 to 60 years (mean, 56 years). Follow-up ranged from one to six years (mean for the groups, 1.4 to 2 years). All patients had follow-up spine x-rays before treatment and at follow-up, at which time any further wedging and compression fractures were recorded. Additional fractures occurred as follows:
Group E: 16%
Group F: 89%
Group E+F: 53%
Group N: 67%

This study suggests that a significantly higher number of vertebral compression fractures occur in patients with postmenopausal osteoporosis who followed a flexion based exercise program, than those using extension exercises. It also indicated that patients who did no exercises were less likely to sustain a vertebral compression fracture than those doing flexion exercises.

Due to the anatomical nature of the thoracic spine, the vertebral bodies are placed into a normal kyphosis. The anterior portion of the thoracic spine carries an excess load which can predispose an individual to fracture. Combine the propensity of flexion based daily activities such as brushing teeth, driving, texting or typing, with the fact that vertebral bodies are primarily made up of trabecular (spongy) bone and you have a recipe for disaster.

In the US, studies suggest that approximately one in two women and one in four men age 50 and older will break a bone due to osteoporosis.2 Now picture the many individuals who think that the only way to strengthen their core is by doing sit ups or crunches, further compressing the anterior portion of the spine. Often these exercises are being taught or led by fitness instructors who unknowingly put their clients at risk. Only 20-30% of compression fractures are symptomatic.3 This means that individuals may continue performing crunches, sit-ups, or toe touches even after they have fractured. No one realizes it until the person may notice a loss in height (they have trouble reaching a formerly accessible shelf or trouble hanging up clothes,) or the fracture is seen on an x-ray for pneumonia, etc. The Dowager’s Hump (hyper-kyphosis) may begin to appear. Or the person sustains another fragility fracture; possibly a hip.

Note that the E Group (Extension) still sustained fractures but significantly less than the other three groups. This suggests that there is a protective effect in strengthening the back extensors which has led to an emphasis on Site Specific back strengthening exercises as well as correct weight bearing activities.

Telling osteoporosis patients that they should exercise without giving them specific guidelines (such as in the Meeks Method) is doing them a disservice. General exercise provides minimal to no benefit in building stronger bones and the wrong exercises could put them at great risk for fractures. Educating our referral sources for the need to recommend therapists trained in correct osteoporosis management and the difference between “right” and “wrong” exercises may be the first step in reducing fragility fractures.

Osteoporosis and Multiple Sclerosis: Patient Study Part 3

The following is part three in a series documenting Deb Gulbrandson, PT, DPT's journey treating a 72 year old patient who has been living with multiple sclerosis (MS) since age 18. Catch up with Part One and Part Two of the patient case study on the Pelvic Rehab Report. Dr. Gulbrandson is a certified Osteoporosis Exercise Specialist and instructor of the Meeks Method, and she helps teach The Meeks Method for Osteoporosis course.

On Maryanne’s third visit, after reviewing her home exercises I told her that today our focus was on alignment. “In dealing with osteoporosis we want the forces that act upon our bodies to line up as optimally as possible. We have gravity providing a downward force from above and we have ground reaction forces coming up from below. Remember back to your first visit when we did the Foot Press in sitting and talked about Newton’s 3rd Law? For every action there’s an opposite and equal reaction and, how by pressing your feet down it helped you to sit straighter and gave more support to your back?” She nodded in agreement.

“Well, there’s another important component to that- one that we call optimal alignment. When we sit or stand in a flexed posture, those two opposing forces do not line up well and can put undue stress and pressure on our body, particularly the vertebral bodies.” I showed her the spine again with an increased flexion (hyper-kyphosis) in the thoracic area. “It’s normal to have a kyphosis in the thoracic spine. What we don’t want is a hyper-kyphosis. We often see the apex of the increased curve around T-7, 8, 9 levels near the bra line. We also call it the “slouch line” because from the front, that’s where we slouch in sitting. A thoracic hyper-kyphosis can lead to hyper-lordosis in the lumbar spine as the body tries to counteract the flexion forces above with extension or arching in the low back. We know that Wolff’s Law states that bone in a healthy person will adapt to the loads under which it is placed.1 But we want those loads to be optimally transmitted; otherwise the adaptation can be problematic.”

With Maryanne sitting in a Perch Posture position on the side of the low mat table, I placed a 4 foot dowel rod alongside her back, touching her sacrum and apex of her thoracic curve. I instructed her to bring her occiput back toward the dowel without extending her neck. I wanted her to do more of a cervical retraction move. She was a good 3+ inches away. Previously I had measured her using the WOD (Wall to Occiput Distance).2 This helps patients understand when they are forward flexed in the upper thoracic and cervical area and becomes an exercise as well. Since Maryanne was not safe in a standing position, we used an armless chair against the wall. I turned it sideways so the side of the chair was snugged up to the wall and transferred her to the chair, sitting so that her sacrum was flush against the wall. “Bring your upper back against the wall without allowing your low back to arch forward”, I told her as I placed a folded towel behind her head. “Now you’re going to press the back of your head into the towel, just as you do when lying down in the Re-alignment routine. Before you perform the Head Press, inhale to prepare, start your exhale, then do the head press. Hold for 3 -5 seconds as you continue to exhale, then relax as you inhale. Do 3-5 reps.”

The Head Press in standing, (or in Maryanne’s case, sitting) is a convenient way to not only strengthen the back muscles isometrically, but also increase awareness of body in space and relationship of head to trunk positioning. For any individual who has developed a forward head position over a period of years, there is a loss of the proprioceptive feedback necessary to know when we’re not in alignment, even if we have the ROM to achieve it. And often a lack of strength and especially muscle endurance to maintain that optimally aligned position is problematic. Using the wall several times a day can assist in building strength and awareness. In Maryanne’s case we needed a folded towel behind her occiput to give her something to press into and prevented her from going into increased cervical extension.

“I still want you to do the Head Press in supine as part of the Re-alignment routine everyday”, I told her. “But also practice it in sitting against a wall, making sure your sacrum is right up against it. Do this several times a day for several minutes, holding 3-5 seconds each. And be sure to use your breath to maintain neutral alignment of your lumbar spine.”
And with that, our work for the day was done.

Osteoporosis and Multiple Sclerosis: Patient Study Part 2

The following is part two in a series documenting Deb Gulbrandson, PT, DPT's journey treating a 72 year old patient who has been living with multiple sclerosis (MS) since age 18. Catch up with Part one of the patient case study on the Pelvic Rehab Report here. Dr. Gulbrandson is a certified Osteoporosis Exercise Specialist and instructor of the Meeks Method, and she helps teach The Meeks Method for Osteoporosis course.

On Maryanne’s second visit, she reported she had been doing her “homework” and didn’t have any questions. Just to be sure, we reviewed them and I had her demonstrate. In Decompression position, she was lying supine with her hands on her abdomen, a common mistake I see. Usually this is due to tightness in pec minor with protracted scapulae. Patients unknowingly resort to the path of least resistance to take the strain off of the muscles. I explained to her that we want to use gravity to gently lengthen those muscles and “widen” the collarbones to allow for improved alignment. With her shoulders abducted to approximately 30 degrees and palms up, I propped a couple of small towels under her forearms which allowed her shoulders to relax into a more posterior and correct position.Osteoporosis Evaluation

“Today we begin the Re-alignment routine,” I said, “starting with the Shoulder Press.” I showed her how to gently press the back of her shoulders down into the mat without arching her lumbar spine. “As you press your shoulders down, exhale through your mouth as if you’re fogging a mirror. This will help activate your core muscles to keep your back in good alignment. Hold for 2-3 seconds, and then relax. Repeat 3 times.” Maryanne looked at me as if I’d lost my mind. “Did you say do 3 reps?” she asked. “I do 2 sets of 20 reps at the gym,” she said with obvious pride in her voice. “Yes, that’s where we start, and there are a couple of reasons. First, these are very site specific exercises which focus on the exact areas that need strengthening. Exercises done in a gym setting are often more general and usually involve compensation.  We are minimizing any compensation such as allowing your low back to arch. There is probably weakness in those upper back muscles as well as the tightness seen in your anterior chest muscles and we need to go slowly. Also, we are simultaneously stretching while we strengthen. Our society is so forward biased (we work on computers, drive cars, make beds, eat- it’s all forward, forward, forward), that the anterior muscles get tight and the upper back muscles get overstretched and weak. We need to reverse that pattern. Take a look at our younger population and their texting postures. Yikes! We will be layering on more exercises as your technique improves so you’ll be doing more than just 3 reps, I promise.”

After the Shoulder Press we proceeded with the Head Press, Leg Lengthener and Arm Lengthener, spending time to make sure her cervical spine stayed in neutral as she pressed her head down into the mat. Head Press (cervical retraction) performed in supine allow patients to have something to press against and helps inhibit the tendency to move into cervical extension. It can also be done standing against the wall with a small pillow or folded towels between the occiput and the wall.

We ended with Maryanne in standing at the kitchen sink to promote functional activities and weight bearing positions.  I reminded her to do the Foot Press through the floor using the Triangle of Foot Support visual. This helped to elongate her spine. “Imagine a bungie cord running from the top back of your head to the ceiling” I said which further increased her standing height. “Now I want you to imagine a shelf running straight out from your breastbone with a glass of some very expensive fine drink sitting on it. Do not spill your libation! Oh, and one last thing Maryanne. Breathe!!!” At which point she collapsed into laughter and our session was over. “Busted”, she said.

Treating Osteoporosis and Multiple Sclerosis

The following case study comes from faculty member Deb Gulbrandson, PT, DPT, a certified Osteoporosis Exercise Specialist and instructor of the Meeks Method. Join Dr. Gulbrandson in The Meeks Method for Osteoporosis on September 22-23, 2018 in Detroit, MI!

The first sight I had of my new patient was watching her being wheeled across the parking lot by her husband. A petite 72-year-old, I could see her slouched posture in the wheelchair. With the double diagnosis of osteoporosis and Multiple Sclerosis (MS) it didn’t look good. However, “Maryanne“ greeted me with a wide grin and a friendly, “I’m so excited to be here. I’ve heard good things about this program and can’t wait to get started.“

Osteoporosis LocationsThat’s what I find with my osteoporosis patients. They are highly motivated and willing to do the work to decrease their risk of a fracture. Maryanne was unusual in that she was diagnosed with MS at a very young age. She was 18 and had lived with the disease in a positive manner. She exercised 3X a week and had a caring, involved husband. They worked out at a local health club, taking advantage of the Silver Sneakers program. Maryanne was able to stand holding onto the kitchen counter but had stopped walking five years ago due to numerous falls. She performed standing transfers with her husband providing moderate to max assist. Her osteoporosis certainly put her at a high risk for fracture.

Even though she had been exercising on a regular basis, she was unfortunately doing many of the wrong exercises. Her workout consisted of sit-ups and crunches. She used the Pec Deck bringing her into scapular protraction and facilitating forward flexion. She was also stretching her hamstrings by long sitting reaching to touch her toes.

Spinal flexion is contraindicated in patients with osteoporosis. A landmark study done in 19841 divided a group of women with osteoporosis into 4 groups. One group performed extension based exercises, a second group did flexion. A third group used a combination of flexion and extension and the fourth was the control and did no exercises. Below are the results 1-6 years later.

  • Extension Group: 16% incidence of fracture or wedging of vertebral bodies
  • Flexion Group: 89% rate.
  • Combination Extension/Flexion: 53% rate
  • No Exercise Group: 67%

The results were astounding. Granted, it was a small study- 59 participants and it was done a long time ago. But this is a one study that no one wants to repeat, or volunteer for!

Several take home messages followed this study.

  1. Flexion is contra-indicated for individuals with osteoporosis.
  2. It’s better to do no exercise than the wrong exercise. The No Exercise group faired better than the Flexion group although at 67% it’s clear that many of our everyday activities- making beds, placing items on low shelves, and now computing and texting put us at risk.

Sadly, many individuals with osteoporosis are told by their physicians to start exercising.......but without any guidance they do what Maryanne did. Just start exercising. And putting themselves at greater risk.

Maryanne was also doing nothing to strengthen her back extensors and scapular area. After giving an overview of the vertebral bodies, pelvis, and hip joint with my trusty spine, I showed both my patient and her husband how forward flexion puts increased compression on the anterior aspect of the spine, particularly in the thoracic curve at T 7, 8, 9, the most common site of compression fractures. We started with Decompression, which is the beginning position for the Meeks method. Many therapists know this as hooklying. This position allows the spinous processes to press against the hard surface of the floor, opening up the anterior portion of the spine and providing tensile forces throughout the length of the spine. With the help of her husband, Maryanne could get down on the floor but I often advise patients who are unable to safely transfer to the floor to lay across the end of their bed. This is less cushy than lying longways where they sleep. Adding a yoga mat or a quilt on top to give more firmness improves the effect.

Supine is the least compressive of all positions; sitting is the most compressive. While Decompression may not seem like much of an exercise it is vital to reduce the effects of gravity and compression on the spine.

We addressed sitting posture by firming up the base of her wheelchair as well as recommending transferring into other chairs and positions frequently throughout the day. Spending time sitting towards the edge of a firm chair in what we call Perch Posture and practicing Foot Presses into the floor created improved alignment in her spine as well as isometrically activating glutes, abs, quads. Using the Foot Press is an example of Newtons 3rd Law, “For every action there’s an equal and opposite reaction” so by pressing her feet down she actually lengthened her torso and head. We also discussed discontinuing the contraindicated exercises in her workout routine and I assured her that the Meeks method would progressively challenge her core (the reason everyone thinks they should do sit-ups) and target the right muscles to help strengthen her bones. We use site specific exercises to target certain muscles that pull on the bone and increase bone strength.2

With instructions to Decompress several times daily to reduce compression on the spine along with the other adjustments made, I felt Maryanne was on her way to reducing her risk of fracture and increasing the quality of her life. She thanked me profusely for the education and the exercise of that session. We both look forward to the next one.

Fractured Wrists: the Canaries in the Coal Mine

The expression, “the canary in the coal mine” comes from a long ago practice of coalminers bringing canaries with them into the coalmines. These birds were more sensitive than humans to toxic gasses and so, if they became ill or died, the coalminers knew they had to get out quickly. The canaries were a kind of early warning signal before it was too late. Even though the practice has been discontinued, the metaphor lives on as a warning of serious danger to come.

Osteoporosis, which means porous bones, has been called a silent disease because often an individual doesn’t know he or she has it until they break a bone. The three common areas of fracture are the wrist, the hip, or the spine. Osteoporosis fractures are called fragility fractures, meaning they happen from a fall of standing height or less. We should not break a bone just by a fall unless there is an underlying cause which makes our bones fragile.

Wrist fractures typically happen when a person starts to fall and puts his or her arms out to catch themselves. They often are seen in the Emergency Department but seldom followed up with an Osteoporosis workup. According to the International Osteoporosis Foundation’s Capture the Fracture program, 80% of fracture patients are never offered screening and / or treatment for osteoporosis. As professionals working with patients who often have co-morbidities, we can be the ones to screen for osteoporosis and balance problems, particularly if our patients have a history of fractures. These screens include the following:

1. Check for the three most common signs of osteoporosis:
a. History of fractures
b. Hyper-kyphosis of the thoracic spine
c. Loss of height equal or greater than 4 cm.

2. Grip Strength
Low grip strength in women is associated with low bone density1

3. Rib-pelvic distance- less than two fingerbreadths.
With the patient standing with their back to you, arms raised to 90 degrees, check the distance from the lowest rib to the iliac crest. Two fingerbreadths or less may be indicative of a vertebral fracture.

A prior fracture is associated with an 86% increased risk of any fracture based on a 2004 meta-analysis by Kanis, Johnell, and De Laet in Bone 2. Fracture predicts fracture. It is our duty as professionals and as human beings to intervene by screening and referring out even if this is not the primary reason we are treating this patient. Fractures from osteoporosis can be devastating, resulting in increased risk of mortality at worst and a diminished quality of life at best. Look for the canaries in the coal mine. Our patients deserve to live the quality of life they envision.
