Spinal Cord Stimulators: Early interventions show high success rate

As a follow up to yesterday's post, I would like to share an example-- how early interventions to treat pain at the source make good sense.

Spinal cord stimulators are medical devices that have been in existence since the late 1960s-early 1970s.
When a patient has chronic back pain, a device like this can be surgically implanted ..the actual device sits in the abdomen, while the electrodes are placed in the epidural space of the spine.  Once activated, the device sends electrical impulses that scramble the pain signal, and in doing so, muffle the pain sensation for that patient.  The device is programmable, so that it the signals it emits can be adjusted  after implantation as needed by the patient's health care team.

A recent study at Regina General Hospital in Saskatchewan regarding these devices yielded some interesting results.  Krishna Kumar, MD and his group studied 443 patients who were using these devices.  Seventy five percent of patients who waited 2 years or less for stimulator implants had a 75 % success rate. Those who received implants 20 years or more after onset of chronic pain showed a mere
15% success rate.  

Keep in mind that not every candidate with chronic back pain is a good candidate for this device. Other issues, such as specific diagnoses, insurance coverage, psychological issues, and other underlying health conditions may prevent patients from being considered for the procedure.  But when a patient is a good candidate for this treatment, and the timing is right, the odds of success are good. And, as the study suggests, sooner is better than later.

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: Sources: prweb;NorthJersey.com;YouTube

Effectiveness Of Ozone Injections Is No Longer Up In The Air

Most of us know someone who has osteoarthritis, if we don't have it ourselves.  Joint replacement surgery is a pretty common remedy when the joint becomes severely damaged and the patient is in a lot of pain.  With risk of complications from such a surgery, perhaps an alternative treatment should be tried first. One such remedy is the injection of a synthetic version of collagen(e.g. Synvisc®) into the affected joint.  This procedure restores the cushioning to a joint that has degenerated over the years. It can diminish the pain substantially and help put off joint replacement surgery for months to years.  The biggest drawback is that these products are expensive.   GoodRX , a web site that can be used to estimate the cost of medications, estimates the cost of these products to be over $1,000 each. Here's another example--and I am not sure how widely accepted this protocol has become since study authors introduced it in November 2015.  Are you r...

Fibromyalgia Week: Day 2

Tender points...click caption for WebMD animation Tender points are a unique feature of fibromaylgia.  There are 18 such points on the human body (9 pairs as shown).  Using special technique by hand or a dolorimeter, a fibromyalgia patient will experience pain in at least 11 points, and there will be at least one painful tender point in each quadrant of the body! One study found that up to 96% of fibromyalgia patients suffer from sleep disorders. It is believed that this is responsible for a deprivation of delta sleep, during which human growth hormone is produced. This hormone is essential to tissue repair. Other common problems in fibromyalgia are fatigue, concentration/memory ("fibro fog"), and depression.  There is no doubt in my mind that just enabling the patient to sleep well on a regular basis would be of great benefit! It is not uncommon for fibromyalgia patients to have coexisting conditions--some of these are lupus, disease, irritable bowel syndrom...
