Scientists in France and England have found that deterioration in motor function in people over 65 can signal impending death.
Scientists have found that the earliest signs in subjects appeared ten years before death
Scientists from the University of Paris, together with colleagues from University College London, began this study at the end of the 20th century. For example, from 1985 to 1988, they studied the impact of social, behavioral and biological factors on health in the long term. It was attended by six thousand volunteers aged 35 to 55 years.
Then, between 2007 and 2016, participants were assessed for their motor functions three times. The study took into account factors such as walking speed, the time it takes to get up from a chair, grip strength, and difficulties in daily life, such as problems with dressing, using the toilet, preparing meals and shopping for groceries.
The third stage took place until October 2019. Then the experts recorded the number of deaths among the subjects.
After analyzing all the factors, experts found that those who had difficulty walking had an increased risk of death by 22%, had problems with grip strength by 15%, rising from a chair by 14%, and by as much as 30% in those who noted difficulties in everyday life.
The researchers also found that among the study participants who later died, indicators of time to get up from a chair were worse in the ten years before death, their own assessment of motor function - in seven years, difficulty in everyday life - in four years.
