Diminished muscle strength, low grip power, and a slow walking pace are all associated with an elevated likelihood of stroke in adults, as reported by the Medical Xpress journal on May 7th.
Within the scope of this research, scientists examined data encompassing over 480,000 individuals aged between 37 and 73, none of whom had experienced a stroke prior to the analysis. Participants were monitored for a span of 16 years, running from 2006 through 2022. Over this timeline, 11,814 confirmed cases of stroke occurred; this total comprised 9,449 instances of ischemic stroke and 2,029 of hemorrhagic stroke.
According to 2026 statistics from the American Heart Association, stroke ranks as the fourth leading cause of death in the United States and remains the primary source of long-term disability. The gathered analysis indicated that patients suffering from muscle mass loss (sarcopenia) face substantially higher mortality rates following a stroke: the death rate in confirmed cases is 46% greater compared to those whose musculature maintains its tone.
It was determined that individuals exhibiting reduced muscle strength have a 30% higher risk of experiencing any type of stroke. The probability of an ischemic stroke increases by 31% for such patients, while the chance of a hemorrhagic stroke rises by 41%. Furthermore, weak grip strength correlates with a 7% escalation in the odds of suffering a stroke.
The most pronounced correlation discovered by the researchers pertains to ambulation speed: a slow gait elevates the risk of this vascular catastrophe by 64% when contrasted with a brisk step. Lu-sha Tong, a neurologist from the Second Affiliated Hospital of Zhejiang University School of Medicine and the study’s author, noted that metrics related to physical activity are typically omitted from stroke risk assessments.
“As individuals age, they often experience a decline in both muscle strength and mass. This erosion is tied to an increased vulnerability to stroke, manifesting through deteriorating physical health, persistent inflammation, and metabolic shifts. Muscle weakness could serve as an early warning signal indicating a heightened stroke risk,” Tong elaborated.
She further emphasized that walking speed is a more consistent and accurate indicator of overall health status than grip strength. In the view of the scientists, integrating swift, standardized checks of physical functions into routine medical practice would facilitate the early identification of at-risk populations, allowing for timely preventative interventions.
