Walking program for chemo-related joint pain


Walking program eased chemo-related joint pain


SAN DIEGO – A 6-week, low-impact walking program relieved joint pain and stiffness and increased the number of minutes per week walking among elderly breast cancer survivors on aromatase inhibitors.
"A breast cancer diagnosis can be an ‘a-ha’ moment for women," Kirsten A. Nyrop, Ph.D, said during a press briefing at the annual meeting of the American College of Rheumatology. "Some of the women with whom we spoke said: ‘My cardiologist told me to walk and my general practitioner told me to walk, but when my oncologist asked me to walk, I started walking.’ "

Dr. Nyrop, of the Thurston Arthritis Research Center at the University of North Carolina at Chapel Hill, and her associates studied 20 patients who were taking an aromatase inhibitor for stage I-III breast cancer and had self-reported joint pain. The walking program they used was the Arthritis Foundation’s Walk With Ease. The program recommends that participants walk 30 minutes per day at least 5 days per week.
"We wanted to be certain we were reaching these women with a message that would resonate with them and a program that they felt was safe, something that they could comfortably do," Dr. Nyrop said.
The researchers administered visual analog scales (VAS) for joint pain, stiffness, and fatigue, as well as Arthritic Self-Efficacy (ASE) scales for joint and pain symptoms. The mean age of study participants was 71 years, 85% were white, and their mean body mass index was 29 kg/m2.
After 6 weeks in the walking program, researchers noticed improvements from baseline in the VAS pain score (effect size = 0.15) and VAS fatigue score (effect size = 0.22); changes in the VAS stiffness score approached statistical significance (effect size = 0.56). "That’s promising," Dr. Nyrop said. Scores on the ASE scales also improved from baseline for pain and fatigue, but the changes did not reach significance.
Significant increases in walking were observed from baseline in terms of the number of times per week walked (mean increase of 1.9 times; effect size = 0.68), number of minutes per walk (mean increase of 8.3 minutes; effect size = 0.48), and total number of minutes walked per week (mean increase of 62.6 minutes; effect size = 0.53).
One study participant wrote: "I absolutely feel the connection between aromatase inhibitors and exercise. On days I don’t walk, I am stiff, but if I walk, I am not stiff. Keep moving; it really helps."
A larger, follow-up study with a randomized controlled design is underway with funding by the National Cancer Institute.
The study was funded by the University of North Carolina Institute on Aging. Dr. Nyrop said that she had no relevant financial conflicts to disclose.

Living with Chronic pain hits the big screen!

Been to the movies lately?  Jennifer Aniston is on the big screen in a recent release titled "Cake."
Her character, Claire is a victim of chronic pain...she belongs to a support group, where all of the members are coming to terms with the suicide of one of their members.  Of course, she also takes pain medication and addiction is another of her problems...and of course there's more!

I guess I am writing this post just to bring readers' attention to the fact that Hollywood has become aware of the crisis that is chronic pain.  This movie is a testament to that. People that don't have to live with this kind of pain don't fully understand the whole story.  Maybe this movie will shed some light on the issues.

Here is the official trailer for the movie:

Herpes As A Helper?

If you've ever had shingles, or known anyone that has experienced it, you probably know that chronic pain can persist following the initial attack (post herpetic neuralgia).  This is because the herpes virus seems to have an affinity for nerve cells.  And while it's not fun to have shingles or post herpetic neuralgia, the herpes virus may be a key in future development of delivery systems for pain management treatments.

Here's the deal--since Herpes simplex has an affinity for nerve cells, researchers are looking a genetically modified, safer version of the virus to deliver genetic material to damaged nerves.  In simple terms, once the genetic material reaches these nerve cells, it will hopefully encode these nerves to ultimately inhibit pain signals.  Animal studies and clinical trials in cancer patients have been encouraging thus far.

This is one of those developments that makes me believe that there is hope for those in chronic pain. Along with so many other exciting d…

The Knee Bone's Connected To The Leg Bone....

Two recent studies have brought a not-so-novel concept into the limelight-the concept being that people who present with knee pain often develop pain in other parts of their bodies.  These studies, known as the Multicenter Osteoarthritis Study (MOST) and the Osteoarthritis Initiative (OAI), were assessed by a Clinical Epidemiology Team as Boston University School of Medicine in an effort to find preventive strategies to combat this trend.

The authors suggest that knee pain may cause individuals to alter their gait in an effort to compensate for their discomfort. In doing so, the alignment of other body joints is altered, and this may be the cause of secondary joint pain, especially hips and ankles. The authors go on to say that the pain in these secondary sites is not necessarily osteoarthritis--perhaps bursitis or some other injury.

Osteoarthritis is a result of wear and tear in the joints.  We may not be able to completely eliminate osteoarthritis from occurring, but some common se…
