Asymmetry of the hand force and its relationship with cognitive and autonomic processes in patients with chronic cerebral ischemia
Using indicators of bilateral asymmetry as markers of the functional state of cognitive and autonomic functions is widespread. However, for the indicator of the bilateral difference in the strength of the hands, the structural and functional organization of this indicator has been little studied. Purpose of the work: assessment of the difference in hand force as an indicator of the current state of cognitive and autonomic processes in patients with CCI. The study involved 154 patients, 105 women, and 49 men, with chronic cerebral ischemia (CCI) stages I - II, aged 47 to 87 years. In patients with CCI, right handers, there is a negative correlation between the wrist strength of the right and left hands with age; the decrease in wrist strength proceeds at a higher rate in the right hand in men than in women. In men, the strength of the right grasp, but not left, hand correlates with the difference between these indicators in the right and left hands; in women, the strength of the right and left hands is significantly correlated with their difference. There is a relationship between the difference in grasp strength of both hands with cognitive and autonomic indicators.
