Physiotherapy Shows Benefits Following Knee Replacement Surgery

According to a recent study published on bmj.com, physiotherapy can improve the daily lives of osteoarthritis patients who have undergone knee replacement surgery. Osteoarthritis is the most common type of disability found in oler people, so total knee replacement surgery is a routinely performed procedure. Since some patients continue to experience problems with everyday tasks shortly after surgery, researchers reviewed data to determine if short term physiotherapy is an effective solution.

The study involved over 600 patients who were reviewed for effectiveness of physiotherapy treatments accordng to improved function, quality of life, walking, range of knee joint motion, and muscle strength. The results found a small to moderate effect of functional exercise on joint motion and quality of life at three to four months after surgery. This effect, however, was not sustained at one year.

The authors believe that, despite inconclusive evidence, these results indicate that patients should be referred for a short course of physiotherapy exercise to provide short term benefits. These findings also suggest that further research would be worthwhile to reduce uncertainty. The lack of high quality research on the effectiveness of physiotherapy programs following total knee replacement is strongly highlighted by this study.

A Study on Restless Legs and Blood Pressure

Restless legs syndrome is an odd, yet common disorder that causes people to continually move their legs, especially at night when they’re trying to fall asleep.

As if that wasn’t bad enough, now there’s new research that shows it may increase one’s blood pressure and overall risk for cardiovascular disease.

This is a neurological problem, sort of in the same family as Parkinson’s.

But this latest research does indeed suggest a spill-over effect on the cardiovascular system.

Helen Catlin is a nurse who can tell you first hand what being a patient with restless legs syndrome is like.

Patients with RLS may report an almost irresistible urge to move the legs.

The sensations usually are worse during inactivity.

It would bother me at night, sometimes I would have trouble going to sleep or sometimes it would wake me up at night, it would be a sensation of not pain, but enough discomfort that you would have to move, an ache a real ache that would only be relieved by moving your legs, says Helen. As it progressed I realized I was waking up because my legs were bothering me.

And those frequent awakenings, common for those with RLS, appear to create a cardiovascular risk.

“You actually wake up a little bit when they do sleep studies and during that period of awakening or almost awaking the blood pressure goes up and then it comes down again, and then you have frequent little awakening, frequent little increases in blood pressure,” says Dr. Howard Maker, a neurologist at Beth Israel Medical Center.

The study found blood pressure rates during periodic leg movements rose by an average of 20 points for the systolic reading, which is the top number, and by an average of 11 points for the diastolic reading, which is the bottom or second number.

The authors argue that drastic blood pressure surges at night have been associated with a higher rate of stroke in the elderly.

Dr. Maker though, says the jury is still out with RLS. Restless leg syndrome may or may not have a bad effect on the cardiovascular system it hasn’t been proven that these little increases in blood pressure have been dangerous, we do know that the patients are grateful that the restless legs is diminished and that is what we are treating, we are making the patients feel better, their quality of life improves.

And, by treating the restless legs, the blood pressure issue presumably would go away.

Helen’s blood pressure typically runs in the low range, so she’s not at risk; but the medications have changed her life in the more obvious way. ” I get a good night sleep, on the medication I am relieved of the symptoms totally. I wouldn’t know what I would do without it.”

Dr. Maker points out this was studied in only ten patients, so, a bigger study is required.

That shouldn’t be hard to do, because RLS is very common as we mentioned. Affecting about 10-15% of the general population, with men and women affected equally. It is often unrecognized or misdiagnosed.

Many patients are not diagnosed until 10-20 years after symptom onset.

Alcohol Can Slow the Onset of Dementia

One drink per day may reduce the onset of dementia in elderly people.

Having one drink per day may impede the progress of cognitive impairment for seniors. A study at the University of Bari, Italy, involving 1,445 people between the ages of 65 through 85, suggests that those who routinely drank one alcoholic beverage per day developed dementia and Alzheimer’s disease at a slower rate than those who didn’t. Of those in the drinking group, only 121 had developed mild cognitive impairment which included mild memory or mental problems.

trend while tracking participants in the the Italian Longitudinal Study on Aging who were followed for three and a half years. It is still unclear how small alcohol consumption protects against dementia but researchers believe that it is possible that alcohol is good for circulation and may slow the hardening of arteries that supply the brain.

Despite this discovery, many experts believe that alcohol use alone won’t stop the onset of dementia and that adopting a healthy lifestyle with diet, exercise, and social stimulation is the best way of protecting yourself. Other studies have already shown that wine contains natural compounds that have an antioxidant effect, which is good for circulation. Alzheimer’s organizations continue to investigate the possible benefits of fruit juice, red wine, and oily fish in efforts to determine ways to help offset the expected numbers of people who may develop dementia in the coming years. Moderate alcohol consumption (one or two glasses of wine, or other alchoholic drinks, per day) has shown a long and consistent association with a reduced risk of morbidity and mortality from a number of common chronic diseases. In addition to antioxidants in wine, stress reduction by alcohol, may be the common denominator behind these benefits.
