Introduction: Nowadays it is believed that cognitive decline may contribute to the formation of gait disturbance and increased risk of falls. Currently the importance of executive functions to maintain proper control of gait is emphasized. The aim of the study was to assess the relationship between the level of executive function, functional and physical capability in patients over 60 years of age.
Materials and methods: The study included 300 patients (199 women and 101 men) aged 60-88 years. In order to screening for cognitive function Mini-Mental State Examination (MMSE) was used. The following researchers tools were used to conduct functional assessment: a) Short Physical Performance Battery (SPPB), b) Timed “Up and Go” (TUG) and c) Fast Walking Test. To assess executive fucntion Trail Making Test (TMT) was selected.
Results: The relationship between the speed of information processing (part A, TMT), executive functions (Part B, TMT), level of functional and physical capability was observed. The strongest positive correlation was noted between the time of TUG test and TMT part B (r=0.32; p<0.01), and also between Fast Gait Test and TMT part A (r=0.27; p<0.01). It has been proven that the level of executive function is related to the level of functional capability (β=0.18; p=0.001). It was found that 15% of variation in the level of the TUG test was explained by age, TMT- B, GDS and BMI.
Conclusions: There is a relationship between level of executive functions, functional and physical capability in patients over 60 years of age. Cognitive processes play an important role in the control of motor functions therefore it is important to incorporate examination of cognitive functions in the early geriatric diagnosis.
