Accelerometer-measured physical activity patterns in daily life and their association with factors of sedentary behavior in people with epilepsy

Objectives: Being physically active is important, but people with epilepsy (PWE) tend to have a sedentary lifestyle. There is limited evidence about physical activity patterns in PWE using objective measures. The aims of this study were: (1) to examine the physical activity patterns of PWE, (2) compare activity patterns between PWE in terms of drug-resistant epilepsy and medically controlled epilepsy with age- and sex-matched healthy controls; and (3) explore the association between physical activity patterns and body function and structure, activity and participation, and quality of life of PWE. Methods: Seventy-three PWE and 74 healthy controls were enrolled. Physical activity data were collected prospectively over a 7-day period using a SenseWear Arm Band. Body function and structure in PWE were evaluated using the Fatigue Severity Scale, 30-second Chair Stand (30CST), Biodex-Fall Risk, Generalized Anxiety Disorder, Beck Depression Inventory, Pittsburg Sleep Quality Index, and Montreal Cognitive Assessment (MoCA). Activity and participation in PWE were measured using Activities-specific Balance Confidence, Timed Up and Go Test, Six-Minute Walk Test, and Tinetti-Balance and Tinetti-Gait. The quality of life of PWE was evaluated using the Quality of Life in Epilepsy Inventory-31. Results: PWE took fewer steps per day and were sedentary for more time compared with healthy controls (7826 vs. 10,564 steps, P = 0.01; 534 min/day vs. 463 min/day, P < 0.001), especially PWE with drug-resistant epilepsy. 30CST, MoCA, and Biodex-Fall Risk were associated with sedentary behavior, with Biodex-Fall Risk explaining 7.2 % of the variance. Conclusions: PWE demonstrated lower physical activity levels compared with healthy individuals, especially those with drug-resistant epilepsy. Our study highlights the need to tailor strategies including postural stability exercises for the enhancement of physical activity levels in PWE.
