Effect of office-based brief high-impact exercise on bone mineral density in healthy premenopausal women
Although there is ample evidence supporting the effectiveness of physical activity in the prevention and treatment of osteoporosis, there are no previous studies to examine the effect of office-based brief high-impact exercise (HIE) on bone mineral density (BMD) in healthy premenopausal women. This study evaluated the effects of office-based HIE on BMD in healthy premenopausal Japanese women. Ninety-one healthy premenopausal women were randomized to receive stretching exercise (SE) or HIE (stretching, along with up to 5 x 10 vertical and versatile jumps) for 12 months.
There was a significant difference in the change in the femoral neck BMD between the groups in favor of the HIE group [0.6% (95% CI: -0.4, 1.7) vs. -1.0% (95% CI: -2.2, 0.2)].
These finding suggested that office-based brief HIE can be recommended for premenopausal women for preventing bone mineral loss.
Dr. Wendy Katzman, PT, DPTSc, OCS and her colleagues at the University of California San Francisco created a 12-week group activity program for women with an average age of 72 who had kyphosis or a stooped posture. The 2009 study was funded by a grant from the National Institutes of Health. The aim was to determine if women could experience improvements in posture, body strength, range of motion, and physical performance through a 12-week group activity program. In all of the women who participated, their kyphosis improved, meaning they stood taller with less of a stooped posture, they improved their strength and range of motion or joint flexibility, along with all of the other variables studied.
Patellofemoral joint force and
stress magnitudes were greater during
the forward lunge short compared to the
forward lunge long at higher knee angles
and were greater with a stride compared
to without a stride at lower knee angles.
Interesting case report about a 55 year old man who experienced the onset of back pain while jogging. He discovered that he had osteoporosis and underwent a vertebroplasty to repair the fracture. He was painfree within one week post surgery.
Atypical Subtrochanteric Fractures with Long-Term use of Bisphosphonates (Fosamax, Actonel, Boniva, Reclast)
Last week, Good Morning America hosted a segment on spontaneous fractures with long-term use of bisphosphonates commonly used to treat osteoporosis. They implicated that these drugs taken for 7-8 years actually make bones more brittle. Here is a link to the story. But please read the following article about the FDA Task force as well. Good Morning America Story…
The FDA and the American Society of Bone and Mineral Research Subtrochanteric Femoral Fracture Task Force (read about the task force here) are convening to investigate this topic. At present these types of fractures are extremely rare and all fractures of this type are under investigation by medical specialists in this field.
When considering drug therapies for bone health, one must consider the risks and benefits. When we know that the risk for someone breaking a bone due to osteoporosis past the age of 50 is 1 out of every 2, sometimes the risks of these rare types of fracture is worth it. I am not advocating the use of drugs, I am just stating that this should be a conversation and a mutual decision by patient and physician.
On a side note, it is currently recommended that patients take a “drug holiday” occasionally when on a bisphosphonate type of drug.
We will keep looking at the research as it comes forward to make informed decisions. So, for now, let’s keep exercising, practicing balance, working on leg strength and spinal extensor strength to aid in fracture prevention and overall health and function!
Just heard an amazing lecture by Dr. Lorimer Moseley at the APTA Combined Sections Meeting in San Diego. “Explain Pain” is a book written by Dr. Moseley and Dr. David Butler (Mobilization of the Nervous System) for chronic pain patients that explains the concept of pain as a perception in our brains. They also call spinal discs “living active force transducers” to help people get away from the concept of a “slipped disc” that doesn’t happen! Very interesting work!
