Abstract EN
Gait variability is associated with falls in clinical populations.
However, gait variability’s link to falls in persons with Multiple Sclerosis (PwMS) is not well established.
This investigation examined the relationship between stride-time variability, fall risk, and physiological fall risk factors in PwMS.
17 PwMS (62.8±7.4 years) and 17 age-matched controls (62.8±5.9 years) performed the 6-minute walk test.
Stride-time was assessed with accelerometers attached to the participants’ shanks.
Stride-time variability was measured by interstride coefficient of variation (CV) of stride-time.
The participant’s fall risk was measured by the short form physiological profile assessment (PPA).
A Spearman correlation analysis was used to determine the relationship between variables.
Increased fall risk was strongly associated with increased stride-time CV in both PwMS (ρ=0.71, p<0.01) and the controls (ρ=0.67, p<0.01).
Fall risk was not correlated with average stride-time (p>0.05).
In PwMS, stride-time CV was related to postural sway (ρ=0.74, p<0.01) while in the control group, it was related to proprioception (ρ=0.61, p<0.01) and postural sway (ρ=0.78, p<0.01).
Current observations suggest that gait variability is maybe more sensitive marker of fall risk than average gait parameters in PwMS.
It was also noted that postural sway may be potentially targeted to modify gait variability in PwMS.
