Abstract:

Objective

To investigate the correlation between body fat percentage (BF) and gait parameters during single task walking (STW) and dual task walking (DTW) in patients with cerebral small vessel disease (CSVD), and to determine whether BF is associated with the risk of falls in CSVD patients.

Methods

A total of 95 hospitalized patients diagnosed with CSVD in Neurology Department of Seventh Medical Center of PLA General Hospital from January 1, 2022, to June 1, 2023,were collected.Data on their fat mass and BF were collected.High BF was defined as exceeding 25.7% in males and 35.9% in females.Based on this criterion, the enrolled patients were categorized into a normal BF group (46 cases)and a high BF group (49 cases).Additionally, gait parameters such as cadence, stride time, speed, and stride length, as well as phase coordination index (PCI), coefficient of variation (CV), and gait asymmetry (GA)were measured during both STW and DTW conditions.The number of falls was also recorded.Generalized estimating equations (GEE) and binary Logistic regression analyses were conducted to explore the relationship among these parameters.

Results

The GEE results indicate significant interaction effects for all gait parameters except for GA, both between and within groups.Therefore, post-hoc analyses were conducted to further investigate these differences: between-group comparison showed that during STW, the high BF group had significant differences in the basal gait parameters (STW, cognitive DTW, motor DTW) and indirect gait parameters (STW, cognitive DTW, motor DTW CV) compared to the normal BF group (all P<0.05);within-group comparison indicated that during DTW, particularly cognitive DTW, all basal and indirect gait parameters in normal BF and high BF groups compared with STW, the differences were significant (all P<0.05).Additionally, regardless of gender, BF was identified as an independent risk factor for falls (male:odds ratio=1.132, 95% confidence interval: 1.009-1.270; female: odds ratio=1.145, 95% confidence interval:1.058-1.239).

Conclusion

There is a significant correlation between BF and gait parameters during STW and DTW in patients with CSVD.Additionally, BF has been identified as an independent risk factor for fall accidents in this patient population.
