Abstract
Introduction
While mild cognitive impairment (MCI) is a risk factor for falls in older adults, the effects of MCI on physical performance associated with MCI have not been adequately characterised. The aim of the study was to profile physical performance patterns associated with MCI.
Methodology
53 older fallers (31 females, 22 males) from the Falls Clinic at Universiti Malaya Medical Centre, aged 60 years and above (76.5±6.6) were screened and categorised into 2 groups – with MCI and non-MCI – using a Visual Cognitive Assessment Test (VCAT) cut-off score of ≥23. Participants’ sociodemographic data were recorded. Participants performed the Senior Fitness Test that consisted of a battery of physical performance tests.
Results
Older fallers with MCI (n=26) had significantly (p<0.05) poorer physical performance compared to the non-MCI (n=27) group in handgrip strength (16.7±4.8 vs 20.7±7.9 kg), Timed Up-and-Go (17.3±9.91 vs 9.54±2.10 s) and 2-minute walk (79.3±29.8 vs MCI 106.3±33.1 m) tests. There were no significant (p>0.05) differences for the 30-second chair stand, chair sit-and-reach and back scratch tests.
Conclusion
Older fallers with MCI had poorer upper body muscle strength, balance and aerobic endurance compared to those with normal cognition. However, flexibility and lower body muscle strength were similar in older fallers with and without MCI. Further studies to evaluate specifically tailored interventions according to the pattern of physical impairment reported with MCI are needed.
