A new paper published in the Journal of Experimental Medicine found pulleys could be used to reduce the risk of stroke and cardiovascular events, but only for people with underlying heart problems.
The study found pulley use was associated with a significantly lower risk of death or hospitalization compared to people who did not use pulleys.
“It is a remarkable finding that there is a protective effect,” said Dr. Andrew S. Brown, professor of medicine at the Harvard Medical School and a co-author of the study.
“But it is also a very preliminary finding, and we need to investigate further.”
Pulleys were first used in the 1920s to help treat strokes, but have since been used for more serious conditions such as cardiac arrest and stroke.
The devices can be used in hospitals, offices, and homes.
The device’s effectiveness depends on how many pulleys are used and how much time the patient is able to use them, as well as how much energy they are being used for.
The researchers used data from the Framingham Heart Study, a nationally representative study that includes nearly 2 million people over a 20-year period.
The study included both adults and children, and has been compared with the National Health and Nutrition Examination Survey (NHANES).
The study looked at the pulley system in 20 major American cities and found that people who were given pulleys reported significantly lower stroke and cardiac events compared to those who did none of the tests.
The results were similar for people who had been on heart medications such as angiotensin-converting enzyme inhibitors or angiotonic antidepressants, but the researchers didn’t find any differences for people on other treatments.
Dr. Brown said there is currently no way to prevent stroke or cardiovascular events by simply stopping the use of pulleys, and added that it is likely the device’s use will continue as it has for the last decade.
“There is no way that this [study] could be replicated for all pulleys or for all patients, but there are certainly some that are safe and others that are not,” he said.
The findings were published in a new issue of the journal PLOS ONE.SOURCE: bit.ly/1vQJH1u JAMA Neurology, online December 1, 2017.
